50 Essential Thought Leaders on STEM in Schools

Introduction

The question is not whether schools should teach science, technology, engineering, and mathematics. The question is why so many students arrive at the end of their schooling convinced they are not a maths person or that science is someone else's territory. The answer, more often than not, lies not in the subjects themselves but in the way they have been taught. The 50 voices in this list have devoted their careers to changing that, and the schools brave enough to listen to them are producing students who solve problems with genuine curiosity rather than reluctant compliance.

STEM education sits at the intersection of some of the most urgent pressures facing schools globally in 2026. The global STEM teacher shortage has become critical: a 2025 study found that the number of new STEM teachers graduating from higher education institutions dropped by 37 per cent in the United States between 2011 and 2022, falling from nearly 32,000 to 20,000 annually. At the same time, the World Economic Forum's Future of Jobs Report 2025 estimates that 59 per cent of the global workforce will need retraining by 2030, with STEM competencies sitting at the heart of that transition. And persistent gaps in who gets to succeed in STEM, shaped by gender, race, income, and geography, mean that countries are leaving enormous reserves of untapped talent sitting idle in underfunded classrooms.

The voices on this list are not content to describe the problem. They are building curricula, leading research programs, founding organisations, teaching daily in classrooms, and advocating with policymakers to close the gap between what STEM education is and what it could be. Several of them have produced work that directly challenges the dominant model of STEM instruction, arguing that procedural drilling without context, without curiosity, and without genuine problem-solving is not STEM education at all. Their discomfort with the status quo is precisely what makes them worth following.

Jonno White works with school leadership teams around the world to build the cultures, communication, and team dynamics that determine whether good ideas take hold or quietly die in the staffroom. As a Certified Working Genius Facilitator and bestselling author of Step Up or Step Out with more than 10,000 copies sold globally, Jonno delivers workshops and facilitation sessions that help school leaders translate the ideas these thinkers champion into practical decisions on Monday morning.

Why STEM in Schools Matters

The stakes of getting STEM education right extend well beyond test scores and university entrance rates. Countries that invest in high-quality, equitable STEM education at the school level are investing in the quality of their economic decision-making, their civic capacity for evidence-based reasoning, and their ability to respond to challenges they have not yet encountered. The global race to produce STEM-capable graduates is real, but it has produced a damaging side effect: schools chasing metrics rather than cultivating genuine scientific thinking in every student, not just the ones already headed for engineering degrees.

The voices on this list understand this distinction. They are not STEM maximalists who believe every child should become a software engineer. They are educators who believe every child deserves access to the habits of mind that science, mathematics, and engineering develop: curiosity, systematic thinking, tolerance for failure, the ability to frame a question precisely, and the confidence to revise a conclusion when the evidence demands it. These habits belong to every human being, in every career, in every community.

If you are a school principal, curriculum director, or education leader who wants to turn the ideas these thinkers champion into practical culture change inside your school or leadership team, Jonno White facilitates school leadership workshops and executive team offsites that help education teams think more clearly, communicate more honestly, and make better decisions together.

How This List Was Compiled

This list was built through a rigorous cross-referencing process drawing on academic publication records, conference speaker histories, practitioner award recipients, curriculum framework contributions, and the geographic and disciplinary diversity of the STEM education field globally. The 50 people selected share three things: genuine, documentable contributions to how STEM is taught and experienced in schools; active public engagement with the profession rather than purely academic publishing; and a disciplinary breadth that spans mathematics education, science communication, technology pedagogy, equity advocacy, curriculum design, and school policy.

A deliberate effort was made to surface voices from outside the well-trodden circuit of North American conference speakers, including practitioners from Australia, New Zealand, Sierra Leone, Canada, and Europe. The list was also built with an editorial commitment to including the researchers and practitioners who are disrupting conventional assumptions about who belongs in STEM, not just those reinforcing the status quo. The people included are the voices a school principal, curriculum coordinator, or education system leader would benefit from following in 2026.

Category 1: Reimagining Mathematics Education

The most heated debates in STEM education often centre on mathematics, because maths is where the most students lose confidence, and where the gap between how the subject is taught and how it could be taught is widest. The six voices in this category have each, in their own way, made the case that mathematics is not a collection of procedures to memorise but a creative, deeply human discipline that most schools have barely scratched the surface of. They are the researchers, teachers, and curriculum innovators who are changing what mathematics feels like for students who previously thought it was not for them.

1. Jo Boaler | Stanford University

Few researchers have had a more direct impact on how mathematics teachers think about their classrooms than Jo Boaler, the Nomellini and Olivier Professor of Education at Stanford University's Graduate School of Education. Her work on mathematical mindsets, growth mindset in mathematics, and the damaging effects of ability grouping and timed testing has reached millions of teachers through her youcubed platform, her online courses, and her 19 books. The concept of mathematical mindset, which holds that all students can achieve in mathematics when given rich, creative, and collaborative learning experiences, has become a genuine pedagogical movement in school systems across the English-speaking world.

Boaler's most recent book, Math-ish: Finding Creativity, Diversity and Meaning in Mathematics, published by HarperCollins in 2024, makes the case that mathematics is not just about precision and correctness but about approximation, estimation, and creative judgment. The book has been widely read by educators who want to move beyond the procedural paradigm that still dominates most school mathematics classrooms. Her co-founded youcubed platform provides free resources, tasks, and professional development for teachers at every level of the K-12 system.

2. Eddie Woo | University of Sydney

The Professor of Practice in the School of Education at the University of Sydney and the teacher known globally as Mister WooTube, Eddie Woo has done more to demonstrate that mathematics can be genuinely exciting than almost any other educator in the past decade. His YouTube channel has accumulated more than 1.7 million subscribers and 150 million views through nothing more than honest, joyful, deeply knowledgeable explanation of mathematical ideas from basic arithmetic through to complex analysis. His message, delivered consistently across books, keynotes, television, and the classroom, is that mathematics is not a filter that eliminates the untalented but a tool that enriches every life.

In 2024, Woo published Eddie Woo's Wonderful World of STEM, co-authored with Alissa Dinallo, bringing his signature enthusiasm for cross-disciplinary STEM thinking to a younger audience. He continues to teach in Sydney schools part-time alongside his professorial work, grounding his thought leadership in daily classroom practice rather than purely theoretical advocacy. His 2026 second season of Ultimate Classroom further extended his public reach in Australian STEM education.

3. Dan Meyer | Amplify

Dan Meyer spent years as a high school maths teacher in California before becoming one of the most cited voices in mathematics education through his Three-Act Math framework and his doctoral work on how students make mathematical sense of visual and narrative problems. Now serving as Vice President of User Growth at Amplify, where he focuses on teacher efficacy and student learning across Amplify's suite of curriculum and technology products, Meyer has been at the centre of building digital mathematics tools that prioritise genuine mathematical thinking over procedural compliance. His blog has been read by hundreds of thousands of teachers globally, and his TED Talk on maths class needing a makeover has been watched millions of times.

Meyer's central argument, that school maths has stripped away the very qualities that make mathematics worth doing, is supported by research and demonstrated through tasks he has designed and shared freely for more than a decade. His work on Amplify Desmos Math, launched in 2024, continues this mission of building learning experiences that require students to notice, wonder, and reason rather than execute algorithms by rote.

4. Vanessa Vakharia | The Math Guru

The founder of The Math Guru, a Toronto-based maths tutoring studio that has become something of a counterculture institution in Canadian STEM education, Vanessa Vakharia is one of the most distinctive voices in the mathematics education conversation. Her book Math Therapy, published by Corwin in 2024, addresses the emotional and psychological dimensions of mathematics anxiety and failure with a directness and warmth that most academic texts avoid entirely. Her argument is that the trauma many students carry from their school mathematics experiences is real, is preventable, and is directly connected to how teachers communicate about what it means to be good at maths.

Vakharia's work extends beyond individual tutoring. She has become a speaker and advocate for rethinking the culture of maths classrooms, including the deeply damaging message that mathematical ability is innate rather than developed. Her active LinkedIn presence and regular content creation make her one of the most accessible and shareable voices in this category for educators who want practical, human-centred perspectives on maths learning.

5. Conrad Wolfram | Wolfram Research

The Strategic Director and European co-founder of Wolfram Research and founder of the Computer-Based Math initiative, Conrad Wolfram has made one of the most provocative and consistently argued cases in STEM education: that the way mathematics is taught in schools, overwhelmingly focused on hand calculation, bears almost no relationship to how mathematics is actually used by anyone outside a classroom. His book The Math(s) Fix: An Education Blueprint for the AI Age, published in 2020, argues that schools should be teaching students to define problems, translate them into mathematical formulations, and interpret computational results, with the computation itself done by computers.

This is not a fringe argument. Wolfram's framework has influenced curriculum thinking in several countries and has generated genuine debate about what mathematics education is actually for in an age where routine calculation is something computers do better than humans. His keynote work and his ongoing leadership of the Computer-Based Math initiative keep this challenge alive in a conversation that otherwise tends toward incremental reform.

6. Matthew Larson | Lincoln Public Schools

The Past President of the National Council of Teachers of Mathematics (2016-2018) and now Director of Elementary Education for Lincoln Public Schools in Nebraska, Matthew Larson has spent his career building the institutional frameworks that translate research on effective mathematics instruction into the policies and practices that govern what happens in actual classrooms. His work during his NCTM presidency focused explicitly on equity in mathematics education, making the case that excellent mathematics teaching is not a privilege for advantaged students but a universal entitlement. In 2025, he received the NCTM Lifetime Achievement Award.

Larson's book Balancing the Equation: A Guide to School Mathematics for Educators and Parents, co-authored with Timothy Kanold, helped school leaders navigate the politically charged terrain between traditional and reform mathematics instruction with practical guidance grounded in research. His LinkedIn presence continues to be active in professional mathematics education discourse, and his institutional influence on curriculum standards remains significant across US school systems.

Category 2: Science Education and Communication in Schools

Science education in schools faces a different challenge to mathematics. The curriculum exists and is broadly accepted. The problem is that science in most classrooms still looks like a lecture followed by a lab that confirms what the lecture already said, a pedagogy that teaches students to verify rather than investigate. The seven voices in this category have each challenged this model, building programmes, tools, and pedagogies that make genuine scientific inquiry possible in real school classrooms with real resource constraints.

7. Christine Cunningham | Museum of Science, Boston

The Senior Vice President of STEM Learning at the Museum of Science in Boston and founder of Engineering is Elementary and its successor Youth Engineering Solutions, Christine Cunningham has done more to make engineering accessible to primary school students than almost anyone else in the field. Her Engineering is Elementary curriculum, which she founded in 2003, has been used by schools across the United States and internationally; in the 2023-24 academic year alone, more than one million students accessed EiE and YES materials. In 2024, she was elected to the National Academy of Education.

Cunningham's research on how young children approach engineering design problems has been foundational to the field of primary STEM education. Her 2018 book Engineering in Elementary STEM Education: Curriculum Design, Instruction, Learning, and Assessment, published by Teachers College Press, brought this work into the academic literature in a way that bridged practitioner and researcher audiences. Her role at the Museum of Science continues to expand the reach of hands-on STEM learning to students who might not otherwise encounter it.

8. Steve Spangler | Steve Spangler Science

A bestselling author, Emmy Award-winning television personality, and one of the most in-demand STEM educators in the United States, Steve Spangler has spent three decades demonstrating that the best entry point for science learning is not a textbook but a genuine moment of wonder. His Science of Engagement approach, developed through more than 2,100 television appearances and years of school-facing professional development work, holds that curiosity is the precondition for all meaningful STEM learning and that teachers who can create that moment of genuine surprise are the most powerful STEM educators in any school.

Spangler's professional development work with educators has reached hundreds of thousands of teachers who have gone on to create science learning experiences in their classrooms that their students still talk about years later. His recognition by TIME Magazine as one of the most influential people of the year acknowledged not just his reach but the quality of the transformation his approach produces in classrooms that adopt it. His active social media presence and ongoing conference work keep him directly connected to the practitioner community.

9. Sian Proctor | Maricopa Community Colleges

A Geoscience Professor at South Mountain Community College within the Maricopa Community Colleges, founder of the Proctor Foundation for Art and Science, and 2024-25 U.S. Department of State Science Envoy for Space, Sian Proctor brings an entirely unique intersection of lived experience and professional expertise to the STEM education conversation. As the first African American woman to pilot a commercial spacecraft, serving as mission pilot on SpaceX's Inspiration4 in 2021, the first all-civilian orbital spaceflight, Proctor has become a global symbol of what STEM pathways can lead to for people who were historically excluded from them.

Proctor's academic background in geoscience and her two decades of classroom teaching before and since her spaceflight give her STEM education advocacy an authenticity that pure celebrity endorsement lacks. Her LinkedIn posts combine personal narrative, science content, and educational advocacy in a way that resonates strongly with both students and the educators who teach them. Her J.E.D.I. Space principles, standing for Justice, Equity, Diversity, and Inclusion, and her Space2Inspire philosophy have become frameworks for a growing community of educators connecting STEM to identity and belonging.

10. Emily Calandrelli | The Space Gal

A mechanical engineer from MIT and the host of Netflix's Emily's Wonder Lab, Emily Calandrelli, known as The Space Gal, has built one of the most accessible science communication platforms for children that exists in English-language media. Her content, spanning Instagram, her Netflix series, and her series of children's books, introduces engineering and space science to children who are still in primary school and would not otherwise encounter these ideas in a format designed for them. Her focus on making engineering accessible specifically to girls and children from underrepresented backgrounds makes her work significant beyond its considerable reach.

Calandrelli's children's book Ada Lace Sees Red extended her reach into classrooms as a literary STEM resource. Her advocacy for broadening who sees themselves as belonging in engineering is grounded in personal experience of the barriers that still exist within STEM culture. School librarians and primary educators who follow her work consistently report that her materials shift children's self-perception about who is allowed to be an engineer or scientist.

11. Okhee Lee | New York University

Professor Okhee Lee of New York University's Steinhardt School is one of the most important researchers in the field of science education equity in the United States and internationally. Her work focuses specifically on how science instruction can be made meaningful and accessible for students who are English language learners, students from non-dominant cultural backgrounds, and students from communities historically excluded from scientific participation. Her contributions to the Next Generation Science Standards placed equity at the centre of the national science education framework in a way that had not previously been codified in curriculum policy.

Lee's 2020 book Teaching Science in Five Steps, co-authored with Scott Greenwald, provided a practical framework for implementing phenomenon-based science instruction that centres student experience and community relevance. Her research has been published in the field's leading journals and has directly influenced how state-level science education leaders think about curriculum design and assessment for diverse learner populations. Her consistent LinkedIn engagement with educators and researchers reflects the breadth of her practitioner-facing as well as academic influence.

12. Andrew B. Raupp | STEM.org

The Executive Director and founder of STEM.org Educational Research, Andrew Raupp has spent more than 20 years building the quality assurance infrastructure for STEM education that the field previously lacked. Since founding STEM.org in 2001, his organisation has worked with more than 142,500 students and 14,000 educators globally, developing the first blockchain-validated STEM credentialing framework for schools, teachers, and educational products. This work addresses a specific and persistent problem in STEM education: the absence of standards by which schools and parents can assess whether a programme claiming to teach STEM is actually delivering genuine learning.

Raupp's LinkedIn presence is among the most substantive in the STEM education field, with regular original writing on the intersection of STEM policy, technology, and educational quality. His 2025 writing on how local community values and essential trades will shape the next decade of STEM education reflects a perspective that is both global in its data and grounded in the realities of specific communities. His work at the intersection of STEM credentialing and blockchain technology places him at a genuinely unusual edge of the field.

Category 3: Maker Education, Technology and the Future of Learning

The maker movement and the integration of technology into STEM education have generated some of the most creative pedagogical thinking in education over the past two decades. The seven voices in this category have each contributed to the argument that students learn STEM best when they are making, building, coding, and solving real problems, not when they are watching someone else explain how things work. Their work spans fabrication labs, robotics, coding, AI literacy, and the flipped classroom model that restructured the relationship between direct instruction and active learning.

13. Mitchel Resnick | MIT Media Lab

The LEGO Papert Professor of Learning Research and Director of the Lifelong Kindergarten group at the MIT Media Lab, Mitchel Resnick has spent decades arguing that the best model for learning at every age is the kindergarten model: creative, playful, exploratory, and project-based. His work on Scratch, the programming language and online community he co-created that has now been used by more than 150 million young people globally, is the most widely deployed argument in history for the proposition that children learn computational thinking best when they are making things they care about.

Resnick's 2017 book Lifelong Kindergarten: Cultivating Creativity through Projects, Passion, Peers, and Play, published by MIT Press, articulates the pedagogical framework that underlies Scratch and his broader approach to learning. In 2025, he received the SIGCSE Award for Outstanding Contribution to Computer Science Education. His consistent conference presence and active academic publishing keep his ideas at the centre of STEM education reform discussions.

14. Paulo Blikstein | Columbia University

An Associate Professor at Teachers College, Columbia University, and the founder of the global FabLearn program, Paulo Blikstein pioneered bringing fabrication labs and maker education into K-12 schools at a time when the concept barely existed. His FabLearn Labs, now operating in schools on four continents, give students access to 3D printers, laser cutters, robotics equipment, and digital fabrication tools, creating hands-on learning environments where STEM disciplines are integrated through the act of building real things. His 2025 research on multimodal learning analytics in makerspaces is producing the evidence base that school systems need to justify this kind of investment.

Blikstein's concern for equity is central to his work. His research specifically targets under-resourced schools and the students who have been most consistently denied access to the kind of hands-on learning that motivates STEM engagement. His LinkedIn posts from the Constructionism 2025 conference reflect his continued active engagement with the global community of educators who are building constructionist learning environments in real schools.

15. Yasmin Kafai | University of Pennsylvania

A professor at the University of Pennsylvania's Graduate School of Education and one of the founding figures in the field of computational participation in education, Yasmin Kafai has spent her career building the research base for coding and making in schools through a lens that is consistently focused on who gets to participate and who does not. Her work on e-textiles, physical computing, and the intersection of craft and coding has opened pathways into computational thinking for students, particularly girls and young women, who might not see themselves as belonging in traditional computer science classrooms.

Kafai's 2016 book Connected Code: Why Children Need to Learn Programming, co-authored with Quinn Burke, is a key text for understanding the educational and civic case for teaching coding in schools. Her most recent work connects computational making with equity frameworks, arguing that broadening participation in computing requires not just lowering barriers of entry but actively redesigning what counts as computational practice to include the full range of ways people make and create with technology.

16. Gever Tulley | Brightworks School

The founder of the Tinkering School and the Brightworks School in San Francisco, Gever Tulley has built the most fully realised argument in education that children learn best when they are trusted to work on hard, real problems with real tools and real materials. His book 50 Dangerous Things You Should Let Your Children Do, published in 2011, became a manifesto for a generation of educators and parents who believed that schools had become too risk-averse to support genuine learning. His Brightworks School, which he founded in 2011, operates without traditional grades, textbooks, or subject divisions, organising all learning around hands-on collaborative projects that integrate STEM and the arts.

Tulley's work is explicitly about recovering the educational value of struggle, failure, and iteration. His TED Talk on tinkering, which has been viewed millions of times, articulated this case to a global audience of educators. His continued work at Brightworks and his speaking engagements keep him connected to the schools and educators who want to build more project-based, maker-oriented approaches to STEM without giving up on rigour or depth.

17. Jon Bergmann | Flipped Learning Global Initiative

One of the co-creators of the flipped classroom model and the Executive Director of the Flipped Learning Global Initiative, Jon Bergmann has had an influence on how STEM teachers use their classroom time that extends to hundreds of thousands of classrooms globally. The core insight of flipped learning, that direct instruction delivered as video homework frees classroom time for the active problem-solving and discussion that students actually need help with, has been particularly powerful in STEM subjects where procedural demonstrations can be pre-recorded and active experimentation and inquiry can fill the class period.

Bergmann's 2012 book Flip Your Classroom: Reach Every Student in Every Class Every Day, co-authored with Aaron Sams, has been translated into 13 languages and used to guide flipped learning implementations in more than 30 countries. His subsequent books extend the model beyond the original concept to address how flipped approaches can support differentiated instruction, project-based learning, and the integration of AI tools into STEM classrooms. He received the 2002 Presidential Award for Excellence in Math and Science Teaching.

18. Amanda Bickerstaff | AI for Education

The CEO and co-founder of AI for Education, Amanda Bickerstaff is working at the most urgent frontier in STEM education in 2026: helping school leaders and teachers develop the professional capacity to use AI tools effectively, ethically, and in ways that genuinely serve students. Her organisation operates across the United States and Australia, providing professional development, resources, and frameworks that help schools move beyond reactive policies about AI to proactive strategies for building AI literacy across the student and staff community.

Bickerstaff's LinkedIn content is particularly valuable for school leaders who are managing the rapid integration of AI tools into their classrooms. She posts regularly on AI literacy frameworks, practical implementation guides, and the equity dimensions of AI in education, including the risk that AI tools designed without diverse communities in mind will replicate rather than reduce educational disadvantage. Her 2025 contributions to the AI in schools policy conversation have been cited in professional development contexts across both the United States and Australia.

Category 4: STEM Equity, Diversity and Access

The most important unfinished conversation in STEM education is about who the field is actually for. The eight voices in this category have dedicated their work to making the answer "everyone," confronting the barriers of race, gender, income, and geography that continue to determine which students emerge from school believing they belong in STEM and which students arrive at university or the workforce already convinced that it is not for them. Their work is not just morally important. It is economically and scientifically important, because the research consistently shows that more diverse STEM communities produce better science.

19. Nichole Pinkard | Northwestern University

An Associate Professor at Northwestern University's School of Education and Social Policy and the founder of the Digital Youth Network and the YOUmedia network of digital learning spaces, Nichole Pinkard has spent her career building the infrastructure for young people from historically underrepresented communities to engage with computational thinking, digital media production, and STEM practices in environments that affirm rather than diminish their identity. Her YOUmedia program, launched in partnership with the Chicago Public Library, has been replicated in libraries, community centres, and schools in cities across the United States.

Pinkard's research on how race and access to technology shape students' STEM identities is foundational to the field of connected learning. Her work demonstrates that the problem of underrepresentation in computing and STEM is not a pipeline problem that begins in university, but an identity problem that begins in primary school when students first get the message that certain kinds of knowledge belong to certain kinds of people. Her consistent advocacy for design justice in educational technology development makes her an essential voice for any school working to close its STEM participation gap.

20. Kimberly Bryant | Black Innovation Lab by Ascend Ventures

The founder of Black Girls CODE, which she established in 2011 and grew into a global movement introducing more than 100,000 girls of colour to technology and entrepreneurship, Kimberly Bryant is now Founder and CEO of the Black Innovation Lab by Ascend Ventures, a venture ecosystem investing in founders building for societal impact and generational wealth. Her decade at the helm of Black Girls CODE demonstrated at scale what intentional community, cultural affirmation, and quality instruction can achieve when STEM education is designed for students who have been told the field is not for them.

Bryant's personal experience as a Black woman who studied electrical engineering at Vanderbilt University in the 1980s and rarely saw herself reflected in her courses or classmates is the motivating force behind everything she has built. Her recognition by the Smithsonian with the Ingenuity Award for Social Progress reflects the depth of her impact on the STEM equity conversation. Her current work with Ascend Ventures focuses on building the economic infrastructure that sustains the innovation ecosystem she has spent her career creating.

21. Reshma Saujani | Girls Who Code

The founder of Girls Who Code and the author of Brave, Not Perfect, Reshma Saujani built the organisation that has now reached more than 500,000 girls and young women globally with computer science education programs that explicitly address the cultural barriers preventing female students from engaging with technology. Her argument, that girls are socialised to avoid failure in ways that make the trial-and-error process of learning to code unnecessarily frightening, has reached a broad mainstream audience through her TED Talk, her books, and her media appearances.

Saujani's 2021 book Pay Up: The Future of Women and Work makes the case that the professional and economic participation of women in technology requires not just education interventions but structural changes in how work, childcare, and professional development are organised. Her ongoing advocacy for girls in computing remains grounded in the specific, practical experiences of students in her programs.

22. Aisha Bowe | STEM Board

A former NASA rocket scientist and the founder and CEO of STEM Board, Aisha Bowe is one of the most compelling personal and professional arguments for what happens when barriers to STEM education are removed for people who were not supposed to be there. Her story, from a difficult academic start in community college to a career at NASA to founding her own STEM education company, has made her one of the most in-demand speakers in the United States on the topic of access, resilience, and the human cost of STEM pipelines that leak talent before it reaches its potential.

STEM Board works with government and educational institutions to build STEM education programs that are genuinely accessible to underrepresented communities, drawing directly on Bowe's experience as both a practitioner and an outsider who had to fight her way into the field. Her recognition as the 2024 STEM for Her Woman of the Year reflects the breadth of her impact across both the education and advocacy dimensions of the STEM equity conversation.

23. Nadia Lopez | Mott Hall Bridges Academy

The principal of Mott Hall Bridges Academy in the Brownsville neighbourhood of Brooklyn, one of the most under-resourced areas in New York City, Nadia Lopez has demonstrated at the level of a single school what is possible when a school leader refuses to accept that socioeconomic disadvantage determines academic outcome. Her school, which she founded in 2010 with an explicit commitment to preparing students from poverty for college and STEM careers, gained global attention in 2015 when a photograph of her with her student Brandon Stanton brought donations that funded full college scholarships for the school's entire class.

Lopez's 2016 book The Bridge to Brilliance: How One Principal in a Tough Community Is Inspiring the World makes explicit what her daily practice already demonstrated: that the expectations a school sets for its students, and the quality of the relationships it builds with its community, are more powerful than any curriculum or technology investment. Her ongoing work at Mott Hall Bridges Academy makes her an active practitioner whose thought leadership is inseparable from daily reality.

24. Felicia Moore Mensah | Columbia University Teachers College

A Professor of Science Education at Columbia University's Teachers College and a past president of the National Association for Research in Science Teaching, Felicia Moore Mensah has devoted her career to understanding and addressing the ways that race, identity, and cultural context shape who succeeds in science education and who feels excluded from it. Her research on science teacher identity, culturally relevant science pedagogy, and the experiences of Black students and teachers in science classrooms has produced some of the most important empirical work in the field on how systemic racism operates within STEM education specifically.

Mensah's edited volume Teaching Science in Culturally Affirming Ways, published with Teachers College Press, brought together a range of perspectives on how science teachers can build classrooms that affirm the cultural identities of their students rather than asking students to set those identities aside when they enter the science lab. Her work in training the next generation of science education researchers at Teachers College ensures her influence extends well beyond her own publications.

25. Edna Tan | UNC Greensboro

A Professor of Science Education at the University of North Carolina Greensboro, Edna Tan is one of the leading researchers in the United States on how marginalised youth, including students of colour, students from low-income backgrounds, and English language learners, can build strong science identities that carry them through secondary schooling and into STEM study and careers. Her theoretical framework of Identity-in-the-discipline provides science teachers with a way of thinking about their students that goes beyond academic performance to ask whether each student sees themselves as someone who does science rather than someone who is judged by science.

Tan's collaboration with Angela Calabrese Barton at the University of Michigan has produced some of the most influential work on out-of-school science learning and its relationship to in-school science identity. Their collaboration has produced foundational practitioner texts for science teachers who want to build more inclusive classrooms without sacrificing depth or rigour.

26. Tiffany Anderson | Hanover County Public Schools

As the Superintendent of Hanover County Public Schools in Virginia, Tiffany Anderson has built a reputation for using system-level leadership to close achievement and opportunity gaps in STEM and across the curriculum, with a particular focus on the districts with the highest concentrations of poverty and racial disadvantage. Her previous leadership work in Jennings School District in Missouri, where she led dramatic improvements in student outcomes through intensive community partnerships, is one of the most cited case studies in educational leadership literature on the relationship between equity and academic achievement.

Anderson's TED Talk on how to close the achievement gap has been viewed millions of times. Her current work in Hanover County demonstrates that the strategies she pioneered in high-poverty urban districts are transferable to mixed-demographic suburban systems, broadening the evidence base for equity-oriented school leadership across the full range of educational contexts.

Category 5: Curriculum Innovation and Pedagogy in STEM

The people in this category are working on the mechanisms by which STEM education changes: the design of curricula, the architecture of learning environments, the theory of how students acquire complex understanding, and the professional development of the teachers who deliver it all. These are the researchers and practitioners who are building the evidence base that school systems need to move from well-intentioned STEM reform toward systematic improvement.

27. Cindy Hmelo-Silver | Indiana University

A Professor of Education at Indiana University and one of the leading researchers in the United States on problem-based learning in STEM contexts, Cindy Hmelo-Silver has spent more than two decades building the theoretical and empirical foundations for collaborative, problem-centred approaches to science and technology education. Her research on how students learn complex systems thinking through collaborative inquiry has been particularly influential in the design of STEM curricula for secondary schools that want to move beyond textbook learning without abandoning rigour.

Hmelo-Silver's 2004 landmark paper on problem-based learning, published in Educational Psychologist, remains one of the most cited articles in the field. Her subsequent work on how teachers learn to facilitate PBL, and what distinguishes effective from ineffective facilitation in STEM classrooms, has practical implications for every school that wants to adopt project-based or inquiry-based approaches without the common pitfall of student confusion replacing student understanding.

28. Manu Kapur | ETH Zurich

A Professor of Learning Sciences and Higher Education at ETH Zurich, Manu Kapur is the originator of productive failure, a learning design principle with profound implications for STEM education at every level. The concept, developed through rigorous experimental research across multiple countries and age groups, holds that students who are allowed to struggle with a problem before being given the solution develop deeper conceptual understanding than students who receive instruction first. This challenges one of the most fundamental assumptions of how STEM subjects are taught: that students need to know the method before they can solve the problem.

Kapur's research has been replicated in studies across the US, India, Germany, and Singapore, demonstrating that productive failure is not a culturally specific phenomenon but a robust learning principle. His 2016 paper on the genesis of productive failure in the journal Instructional Science is one of the most-cited works in learning sciences. His ongoing work at ETH Zurich continues to refine the conditions under which struggle enhances learning and those under which it simply produces frustration.

29. Kathy Hirsh-Pasek | Temple University

A Professor of Psychology at Temple University and a Fellow at the Brookings Institution, Kathy Hirsh-Pasek is one of the world's leading researchers on the science of learning in young children, with particular expertise in play-based STEM learning in the early years. Her work makes the case, backed by substantial empirical evidence, that the most effective STEM learning for young children looks like rich, guided play rather than formal instruction, and that early childhood STEM programs that prioritise playful exploration produce better long-term outcomes in scientific reasoning and mathematical thinking than programs that emphasise early academic drilling.

Hirsh-Pasek's 2003 book Einstein Never Used Flashcards, co-authored with Roberta Michnick Golinkoff, brought her research to a mainstream audience with lasting effect. Her subsequent books, including Becoming Brilliant, co-authored with Golinkoff, extend this argument to the full range of skills that schools and societies need from the next generation. Her Brookings work continues to bridge research and policy on how schools and families can support the development of children's natural scientific curiosity rather than inadvertently suppressing it.

30. Chris Dede | Harvard Graduate School of Education

A Professor at the Harvard Graduate School of Education and one of the field's most sustained voices on the relationship between emerging technologies and the transformation of STEM learning, Chris Dede has been thinking and writing about how digital environments can extend STEM education beyond what brick-and-mortar schools can deliver since the early 1990s. His research on multi-user virtual environments, augmented reality for STEM learning, and the use of games and simulations in science classrooms has influenced how technology companies, curriculum developers, and school systems think about what technology is actually for in education.

Dede's 2009 book Scaling Up Success: Lessons Learned from Technology-Based Educational Improvement, co-edited with John Richards, is a key text for education leaders thinking about how to move from pilot programs to system-wide change in STEM education. His more recent work on immersive learning environments and their specific applications in STEM contexts has positioned him as one of the field's most credible guides to the genuine potential and real limitations of emerging technology in school learning.

31. Jal Mehta | Harvard Graduate School of Education

A Professor at the Harvard Graduate School of Education and the author of one of the most searching critiques of school reform in the United States, Jal Mehta is not primarily a STEM education specialist but a systems thinker whose analysis of why educational reform so rarely produces the changes it promises has profound implications for anyone attempting to reform STEM education at school or district level. His 2013 book The Allure of Order: High Hopes, Dashed Expectations, and the Troubled Quest to Remake American Schooling is required reading for anyone who wants to understand why the most thoughtful STEM curriculum innovations so often fail to scale.

Mehta's more recent work on deeper learning, including the book In Search of Deeper Learning, co-authored with Sarah Fine, identifies the pockets of genuinely transformative education that exist within conventional school systems and asks what they have in common. For STEM educators specifically, this work is valuable because it distinguishes between surface-level STEM activities and the kinds of deep engagement with scientific thinking that actually change how students relate to knowledge.

32. Sarah Bush | University of Florida

An Associate Professor of Mathematics Education at the University of Florida and co-creator of the Innov8 Framework for STEM education, Sarah Bush is one of the most active practitioner-facing voices in the United States on how classroom teachers can build genuinely integrated STEM experiences rather than treating science, technology, engineering, and mathematics as four separate subjects that occasionally share a label. Her work on the Innov8 Framework, developed with Kristin Cook, provides teachers with a flexible, structured approach to curriculum design that puts imagination and curiosity at the centre of STEM learning rather than treating them as extras.

Bush's 2025 book Sparking Innovation in Children Through STEM Exploration, co-authored with Kristin Cook, was described by reviewers as one of the most practically useful STEM education texts for classroom teachers in years. Her active conference presence and LinkedIn content keep her connected to the practitioner community in ways that many academic researchers are not, making her work genuinely influential at the classroom level rather than only in the research literature.

33. Hosun Kang | UC Irvine

An Associate Professor of Education at the University of California Irvine, Hosun Kang is one of the leading researchers in the United States on how science teachers develop the professional knowledge and practice needed to teach in genuinely equitable and intellectually rigorous ways. Her work sits at the intersection of teacher professional learning, science education reform, and equity, asking not just what good science teaching looks like but how teachers actually develop the complex expertise it requires and what school systems can do to support that development rather than undermining it.

Kang's research on ambitious science teaching, particularly in contexts with high proportions of English language learners and students from non-dominant cultural backgrounds, has contributed to some of the most practically useful professional development frameworks currently operating in US school systems. Her 2023 publications on teacher learning communities in STEM contexts provide school leaders with evidence-based guidance on how to design professional development that actually changes classroom practice.

Category 6: Global and Policy Voices in STEM Education

STEM education is shaped as much by policy as by pedagogy. The people in this category are working at the intersection of research, policy, and systems change, asking not just what happens in individual classrooms but what happens in the systems that surround those classrooms: funding decisions, curriculum frameworks, teacher preparation, assessment regimes, and international benchmarking. Their work matters because even the best classroom STEM teaching is limited by the system in which it operates.

34. Pasi Sahlberg | University of Melbourne

A Professor of Educational Leadership at the University of Melbourne and one of the most widely read education policy commentators in the world, Pasi Sahlberg brought global attention to the Finnish education system through his 2011 book Finnish Lessons, which has sold hundreds of thousands of copies and been translated into more than 30 languages. His work makes the case that the countries producing the best student outcomes in STEM and across the curriculum are the ones that invest in teacher quality, trust teacher professionalism, and resist the standardised testing, competition, and marketisation that flatten rather than develop the professional capacity of teachers.

Sahlberg's recent Australian work, including his membership of the federal government's Expert Panel on school funding and his 2025 co-authored writing on fully funded public schools, demonstrates that his influence extends from descriptive analysis of successful systems to active policy advocacy in the Australian context. His LinkedIn posts from his Melbourne base combine international data with specific Australian policy analysis, making him one of the most substantive voices in the Australasian STEM and education policy conversation.

35. Vikas Pota | T4 Education

The CEO of T4 Education and founder of the World's Best School Prize, Vikas Pota has built the global infrastructure for recognising and amplifying school-level innovation in STEM education and across the curriculum, connecting schools from more than 100 countries through a prize framework that gives visibility to the kind of transformative practice that usually stays invisible because it happens in a school in a rural community in a country with no education media presence. The World's Best School Prize, run in partnership with organisations including the Massachusetts Institute of Technology, has created a genuinely global conversation about what school excellence looks like beyond the PISA-dominated discourse.

Pota's LinkedIn presence is consistently substantive, combining global data on school innovation with specific stories from schools in emerging markets that are doing remarkable things with very limited resources. His advocacy for surfacing the voices of educators from the Global South in the global education conversation has helped shift the STEM education discourse away from its historically North American and European centre of gravity.

36. David Sengeh | Government of Sierra Leone

The Chief Minister and Chief Innovation Officer of the Government of Sierra Leone, David Sengeh previously served as Minister of Basic and Senior Secondary Education from 2019 to 2023, where he led some of the most ambitious education reforms on the African continent, including the introduction of free secondary education for all children and the Radical Inclusion Policy that reversed a ban on pregnant girls attending school. His background as an MIT-trained biomedical engineer who developed prosthetic limbs for amputees in Sierra Leone before entering government gives his education advocacy a technical credibility and a human grounding that most policy voices lack.

Sengeh's TED Talk on inclusive education, which has been viewed millions of times, makes the case that the purpose of education is not to select the most academically capable children but to find and develop the capability in every child. His ongoing policy leadership at the most senior levels of Sierra Leone's government, and his global advocacy for the idea that developing country contexts can innovate faster and more radically than entrenched systems, makes him an essential voice for any global conversation about what STEM education for all actually requires.

37. Linda Darling-Hammond | Learning Policy Institute

The Chief Knowledge Officer of the Learning Policy Institute, having served as its founding President and CEO from 2015 to 2025, Linda Darling-Hammond has produced the most comprehensive evidence base in existence on the relationship between teacher quality, teacher preparation, and student outcomes in STEM and across the curriculum. Her work has shaped teacher preparation policy in multiple US states and internationally, and her contributions to the design of equitable assessment systems have influenced how schools in dozens of countries think about what they are measuring and why.

Darling-Hammond's 1997 book The Right to Learn: A Blueprint for Creating Schools That Work remains one of the most cited texts in American education policy. Her ongoing work through the Learning Policy Institute, where she has led or co-authored hundreds of policy briefs, reports, and research syntheses on teacher quality and school improvement, continues to provide the evidence base for system-level decisions about STEM education in ways that reach far beyond any single classroom.

38. Stephen Pruitt | Southern Regional Education Board

The former President of the Southern Regional Education Board and the former Kentucky Commissioner of Education, Stephen Pruitt is one of the most influential figures in the development of the Next Generation Science Standards and in the translation of those standards into state-level policy and curriculum frameworks across the United States. His leadership in the NGSS development process gave him a unique vantage point on the political and technical challenges of aligning a national science education framework with the diverse needs and contexts of 50 state education systems.

Pruitt's work at SREB, which covers 16 southern US states with some of the country's highest concentrations of educational disadvantage, focuses specifically on how STEM education investment can support the economic transformation of communities where the skills mismatch between available jobs and available workers is acute. His consistent advocacy for treating STEM education as an economic development tool, not just an academic exercise, gives his policy work a pragmatic credibility that resonates with legislators and business leaders as well as educators.

39. Heidi Schweingruber | National Academies

The Director of the Board on Science Education at the National Academies of Sciences, Engineering, and Medicine, Heidi Schweingruber has overseen the production of some of the most important consensus documents in the history of STEM education policy in the United States. These include the 2012 Framework for K-12 Science Education, which provided the scientific and educational foundation for the Next Generation Science Standards, and the 2025 Equity in K-12 STEM Education: Framing Decisions for the Future report, which provides the most comprehensive current framework for how decision-makers at every level of the education system should approach equity in STEM.

Schweingruber's role is fundamentally infrastructural: she builds the research syntheses and consensus frameworks that give policymakers, curriculum developers, and school leaders a shared evidentiary foundation for the decisions they make about STEM education. The scale of her influence is therefore largely invisible but extremely broad, operating through the frameworks that shape what teachers are asked to teach and how student learning in STEM is assessed.

40. Christine Reich | TERC

The President of TERC, a non-profit educational research and development organisation based in Cambridge, Massachusetts, Christine Reich brings the perspective of informal STEM learning to the broader conversation about how children develop scientific curiosity and competence. Her background as a social science researcher and former museum executive gives her an unusually broad view of the full ecosystem of STEM learning that surrounds and supports what happens in school classrooms.

Reich joined TERC as president in 2025, bringing with her a deep commitment to advancing STEM education opportunities for all learners through research, curriculum development, and professional learning for educators. TERC's work on accessible STEM for students with disabilities, on culturally responsive science curriculum, and on the integration of community-based learning into formal STEM instruction represents some of the most practically grounded research available to schools seeking to build more inclusive STEM programs.

Category 7: Emerging and Mid-Tier Voices Reshaping the Field

The final eight voices on this list represent a deliberate editorial choice to surface the practitioners, researchers, and advocates who are doing genuinely important work in STEM education without yet having the global platform of the voices in earlier categories. Several of these people are operating at the classroom or district level, or building new organisations, or doing research that has not yet made it from academic journals into mainstream education discourse. They are the voices most worth following early in 2026 because the trajectory of their work is upward and the quality of their contribution is high.

41. Laura Ascenzi-Moreno | Brooklyn College

An Associate Professor of Childhood and Early Childhood Education at Brooklyn College of the City University of New York, Laura Ascenzi-Moreno is one of the field's leading voices on the intersection of bilingualism, translanguaging, and STEM education. Her research makes the case that bilingual students are not disadvantaged in STEM learning but actually bring cognitive and cultural resources that schools systematically fail to recognise and build on. Her framework for translanguaging in science classrooms gives teachers a practical approach for valuing students' full linguistic repertoire rather than treating their home language as a barrier to science learning.

Ascenzi-Moreno's 2020 book Rooted in Strength: Using Translanguaging to Grow Multilingual Readers and Writers, co-authored with other colleagues, brought her approach to a broader practitioner audience. Her ongoing work on how bilingual students experience and navigate STEM classrooms in New York City provides some of the most granular evidence available on what equity in urban STEM education actually requires at the classroom level.

42. Jennifer Ruef | University of Oregon

An Assistant Professor of Mathematics Education at the University of Oregon, Jennifer Ruef is building an evidence base for an idea that sounds simple but is surprisingly rare in practice: that mathematics classrooms where students feel genuinely safe to take risks, make mistakes, and reason aloud produce better mathematical learning outcomes, particularly for students who have previously been marginalised within the mathematics classroom. Her research on classroom norms, mathematical agency, and what she calls justly just mathematics classrooms provides teachers with both a theoretical framework and practical tools for building the kind of culture that makes genuine mathematical thinking possible for all students.

Ruef's 2021 paper on mathematical agency in the Journal of Mathematical Behavior is one of the field's most practically useful recent contributions to understanding what it looks and feels like when students experience themselves as genuine mathematical thinkers rather than consumers of others' mathematical reasoning. Her active LinkedIn engagement with practitioner audiences makes her research more accessible than most academic work in the field.

43. Benjamin Glover | STEM Detective

The founder of STEM Detective and a 2026 Fellow of the Texas Education Policy Institute, Benjamin Glover is working at the intersection of STEM education, community science, and educational access in the Houston schools with the highest concentrations of disadvantage in the city. His work with Carrillo Elementary, which achieved Exemplary ratings in 2026 STAAR testing, demonstrates what is possible when STEM curriculum is delivered with genuine rigour and genuine care for the students it serves. His LinkedIn content is among the most substantively practical in the STEM education space, combining policy engagement with direct classroom-level evidence.

Glover's presence at SXSW EDU 2026 and his engagement with national conversations about AI in education from a practitioner perspective give his work a credibility and immediacy that purely academic voices cannot replicate. His specific focus on the schools that need high-quality STEM education most and tend to receive it least makes him a significant emerging voice in the equity dimension of the STEM education conversation.

44. Rachael Bonoan | Brown University

A researcher and lecturer at Brown University working on science education equity and access, Rachael Bonoan is building an evidence base for how science museums, informal learning programs, and formal schools can work together to provide all children, regardless of income or neighbourhood, with meaningful access to genuine scientific inquiry. Her particular focus on the role of curiosity, and on how early childhood science experiences shape the scientific identity that children carry into their school years, connects the informal and formal STEM learning ecosystems in ways that school leaders can act on.

Bonoan's research on who benefits most from science museum programs, and how those programs can be designed to serve students from low-income backgrounds as effectively as those from affluent families, has direct practical implications for schools seeking to extend their STEM programs beyond the classroom into community partnerships. Her active engagement with science education researchers and practitioners on LinkedIn makes her work accessible to the practitioner audience as well as the research community.

45. Katrina Schwartz | KQED MindShift

The Managing Editor of KQED's MindShift blog and one of the most important education journalists covering the STEM learning space, Katrina Schwartz occupies a unique position at the interface between research and practice in STEM education. Her work at MindShift translates peer-reviewed research on learning science, STEM pedagogy, equity, and technology into accessible, practical articles that hundreds of thousands of teachers, school leaders, and parents read regularly. This translation work is genuinely undervalued in the education ecosystem but is essential for ensuring that research findings actually reach the classrooms where they could make a difference.

Schwartz's coverage of STEM education specifically has included deep dives into project-based learning, the science of mathematical mindsets, coding in schools, and the equity dimensions of who gets access to high-quality STEM instruction. Her willingness to cover the genuinely difficult conversations in STEM education, including the research on what does and does not work in STEM reform, makes MindShift a more trustworthy resource than most education media platforms.

46. Gavin McLean | EDconnect New Zealand

A STEM and Digital Curriculum Consultant at EDconnect in New Zealand and a Global Innovation Practitioner at Business Wave, Gavin McLean is one of the most active mid-tier voices in the Australasian STEM education conversation. His work bridges the gap between curriculum design theory and practical classroom implementation across New Zealand schools, helping teachers and school leaders navigate the specific challenges of building genuine STEM integration in a system with fewer specialist resources than larger national education systems. His LinkedIn content is regularly engaged with by educators across New Zealand, Australia, and Southeast Asia.

McLean's role with STEM.org covering Oceania gives his work an international framework that connects New Zealand classroom practice to global STEM education standards and research. His perspective as a practitioner-facing consultant rather than a purely academic voice makes him particularly valuable for school leaders who are looking for guidance on implementation rather than theory.

47. Sarah Chapman | Royal Australian Chemical Institute

A former secondary science teacher of 19 years and Lead Coach for the International Chemistry Quiz at the Royal Australian Chemical Institute, Sarah Chapman is one of the most active and practically grounded voices in Australian STEM education advocacy. Her 2016 Barbara Cail STEM International Fellowship, which took her to schools, universities, and government departments around the world to research what was working to increase STEM participation among young people, particularly girls, produced insights she has been sharing with Australian and international educators ever since. Her work leading the ICQ Global Chemistry Educators Program in Beijing in January 2025 demonstrated the international reach of her school-facing STEM education work.

Chapman's LinkedIn content is distinguished by its direct relevance to classroom science teachers and school STEM coordinators, combining international research with practical strategies that can be applied in Australian school contexts. Her advocacy for hands-on, inquiry-based science learning as the primary lever for increasing student engagement with STEM, particularly among girls, is backed by her own classroom experience as well as her international research.

48. Kristina Ishmael | ISTE

A Senior Policy Analyst at the International Society for Technology in Education and a former classroom teacher, Kristina Ishmael sits at the intersection of educational technology policy and practice in ways that directly affect how schools implement STEM programs. Her work at ISTE focuses on ensuring that technology integration policies in schools are designed with equity as a central concern, particularly around access to the devices, connectivity, and professional development that make technology-enabled STEM learning possible for all students rather than just those in well-resourced schools.

Ishmael's active LinkedIn presence connects her policy work to a practitioner audience that benefits from understanding the policy landscape surrounding the technology decisions that affect their classrooms. Her specific expertise in digital equity, including the persistent gaps in broadband access and device availability that continue to limit what is possible in STEM classrooms in rural and low-income communities, makes her an important voice for school leaders navigating the relationship between technology investment and equitable outcomes.

49. Tonya Rooney | Australian Catholic University

An Associate Professor in Early Childhood Education at Australian Catholic University's Canberra campus, Tonya Rooney is one of the leading researchers in Australia on STEM learning in early childhood and primary school settings, with a particular focus on how young children's natural wonder, curiosity, and sense of agency can be preserved and extended rather than prematurely replaced by formal instructional approaches. Her research on how STEM is introduced in early learning settings, and on what counts as STEM thinking for children in the birth to eight years age range, challenges the assumption that STEM education only becomes meaningful once children are in secondary school.

Rooney's work with the Australian Government's STEM education agenda and her publications in journals including the International Journal of Early Years Education provide a research base for early childhood educators and primary school teachers who want to build genuine scientific and mathematical thinking from the very beginning of a child's formal education, rather than waiting until students are old enough to work through a textbook.

50. Jonno White | Consult Clarity

The people on this list are the thinkers. Jonno White is the person school leaders bring in when they are ready to act on what the thinkers say. The best STEM education reform in the world fails if the leadership team responsible for implementing it cannot communicate clearly, resolve conflict honestly, or build the team trust that sustains change over time. Jonno White, a Certified Working Genius Facilitator, bestselling author of Step Up or Step Out with more than 10,000 copies sold globally, and host of The Leadership Conversations Podcast with more than 230 episodes reaching listeners in 150 countries, works with school leadership teams around the world to build exactly that capacity.

His facilitation work, delivered in schools and school networks across Australia, the UK, USA, Singapore, New Zealand, India, and beyond, gives leadership teams the tools to have the difficult conversations that STEM reform requires and to make the aligned decisions that any sustained change needs. International travel is often far more affordable than school leaders expect. To bring Jonno into your school for a leadership session, workshop, or offsite, email jonno@consultclarity.org.

Notable Voices We Almost Included

Several people were seriously considered for this list and came very close to making the final 50. Mark Rober, the former NASA engineer and YouTube creator with more than 71 million subscribers, is one of the most influential STEM communicators alive today. His approach to making science curiosity contagious has reached an entire generation, but his primary platform is YouTube rather than LinkedIn, and his school-facing professional development work is limited compared to others on this list. Grant Sanderson, the creator of 3Blue1Brown, has done more to make advanced mathematics visual and intuitive than almost any other person in the world, but his work is aimed more at older students and adults than at K-12 classrooms. Hank Green, who co-created CrashCourse and is among the most important science communicators of his generation, has an enormous reach and genuine impact but operates primarily outside the school-leadership audience this list is designed to serve.

Brene Brown, Adam Grant, and Simon Sinek would appear on many lists adjacent to this one, and their contributions to leadership and organisational culture are genuinely foundational. We deliberately moved past these well-known names to surface voices whose work is specifically grounded in the STEM education context and who are building their public profile in ways where being featured on a list like this offers genuine professional value.

Common Mistakes When Engaging with STEM Education Thought Leadership

Following STEM education thought leaders is easy. Translating their ideas into school practice is where most schools stumble. The most common mistakes are not about lack of enthusiasm but about how ideas are applied when they leave the conference room and enter the classroom.

The most frequent mistake is treating STEM as an add-on rather than an integration. Schools adopt a thought leader's framework and create a dedicated STEM period on the timetable, missing the entire point that the most powerful STEM pedagogy is cross-disciplinary by design. The thinking of people like Cindy Hmelo-Silver and Paulo Blikstein is built around the irreplaceable value of genuine integration. A STEM lab that operates in isolation from the rest of the curriculum is better than nothing, but it is not the transformation these thinkers are describing.

The second mistake is applying equity frameworks cosmetically. A school that adds a coding program for girls without examining the gender dynamics in its own mathematics and science classrooms has read the thought leadership without understanding it. The work of Kimberly Bryant and Nichole Pinkard is not about programming events. It is about a systematic rethinking of whose curiosity is nurtured and whose is inadvertently suppressed from the very first year of school.

A third common error is chasing the technology rather than the pedagogy. Schools that invest in makerspaces, robotics equipment, or AI tools without the professional development to help teachers use them purposefully consistently find that the equipment collects dust. The research from Paulo Blikstein and Chris Dede is explicit: the technology is not the lever for change. The pedagogy is the lever, and the technology supports it.

Fourth, many schools engage with the reform mathematics movement of Jo Boaler or the inquiry science movement of the NGSS without adequately preparing teachers for the pedagogical shift those approaches require. Teachers who were themselves trained in procedural mathematics cannot be expected to facilitate open mathematical investigation without substantial, sustained professional development. The research from Hosun Kang and Linda Darling-Hammond on teacher learning makes this point emphatically.

Finally, schools frequently fail to connect their STEM education reform to their leadership and culture work. The most sophisticated STEM curriculum in the world will not survive a staffroom culture of fear, a senior leadership team that cannot resolve conflict, or a professional development program that is box-ticking rather than transformative. The quality of the relationships and trust within a school's leadership team is the invisible infrastructure on which everything else depends.

Implementation Guide: Taking Action on STEM Education Thought Leadership

Building a serious practice of learning from the voices on this list begins with making it institutional rather than individual. One teacher who reads Jo Boaler or follows Pasi Sahlberg can bring valuable ideas into their classroom. A whole school leadership team that collectively engages with the STEM education thought leadership conversation can make the structural decisions that create conditions for genuine change.

Start by identifying the specific challenge your school is most urgently facing in STEM education. Is it student disengagement, particularly in secondary mathematics? Is it underrepresentation of girls or students from low-income backgrounds in STEM pathways? Is it a pedagogy gap between what research says about inquiry learning and what is actually happening in your science classrooms? The thought leaders most relevant to each of these challenges are different, and beginning with the most relevant voice is more useful than attempting to absorb all 50 simultaneously.

Once you have identified your priority challenge and the two or three voices most relevant to it, build a structured professional learning community around their work. The most effective format is a small group of teachers and leaders who read, discuss, implement, and reflect on a piece of work over a single semester, rather than a whole-school PD day that presents a framework without the follow-through. The research on teacher professional learning, summarised comprehensively in Linda Darling-Hammond's work, is unambiguous: short, disconnected professional development produces short, disconnected changes in practice.

Connect your STEM reform work to your leadership culture work. The schools that make the most sustained progress on STEM education are invariably the ones where the leadership team is functioning well: communicating honestly, managing disagreement constructively, and making decisions with alignment rather than compliance. Jonno White facilitates executive team offsites and leadership workshops specifically designed for school leadership teams. International travel is often far more affordable than schools expect. Email jonno@consultclarity.org to discuss what is possible for your context.

Use the voices on this list as professional development partners. Follow them on LinkedIn, engage with their content, and share what you are finding with your colleagues. Many of these people, particularly those in the mid-tier category of the list, actively respond to substantive engagement from educators. The professional development value of a genuine online dialogue with a researcher who is working on exactly the problem you are trying to solve cannot be replicated in any conference session.

Frequently Asked Questions

Who are the most influential thought leaders in STEM education globally?

The most influential voices in STEM education span mathematics education reform, science pedagogy, equity advocacy, curriculum innovation, and policy. Among the most consistently cited are Jo Boaler for mathematical mindsets, Mitchel Resnick for computational and maker learning, Christine Cunningham for primary engineering education, Pasi Sahlberg for international education policy, and David Sengeh for equity-centred education reform in the Global South. The 50 voices on this list represent a broader and more geographically diverse cross-section of genuine influence in the field than most existing compilations.

What is STEM education and why does it matter in schools?

STEM education refers to interdisciplinary learning experiences built around science, technology, engineering, and mathematics, with a particular emphasis on inquiry, problem-solving, and the application of knowledge to real-world challenges. It matters in schools because the habits of mind it develops, including systematic thinking, hypothesis testing, the ability to frame a precise question, and the tolerance for ambiguous problems, are valuable far beyond any specific career pathway. It also matters because the ability to reason quantitatively and scientifically is becoming a baseline requirement for economic participation and civic engagement in a world increasingly shaped by data, technology, and complex environmental challenges.

How can schools improve STEM education outcomes?

The research consistently points to three levers: teacher quality and professional development, curriculum quality and coherence, and the school culture that either supports or undermines risk-taking and genuine inquiry. Schools that improve STEM outcomes invest first in helping teachers develop the pedagogical expertise to facilitate open inquiry rather than delivering demonstrations. They adopt curricula grounded in genuine disciplinary practices rather than rebranded content delivery. And they build leadership cultures where experimentation and honest reflection are genuinely valued rather than officially endorsed but practically punished.

Why is there a STEM teacher shortage globally?

The STEM teacher shortage has multiple causes. The most significant is competition: people qualified to teach STEM subjects have attractive career alternatives in industry, and the professional conditions in teaching, including workload, autonomy, and salary, have not kept pace with those alternatives in most countries. A 2025 study found that new STEM teacher graduation in the US dropped 37 per cent between 2011 and 2022. At the same time, student demand for STEM learning is growing, particularly as AI and automation reshape career pathways. Addressing the shortage requires both improving professional conditions in teaching and building more creative pathways into STEM classroom roles.

How was this list compiled?

This list was built through cross-referencing academic publication records, conference speaker histories, practitioner award databases, curriculum framework contribution records, and active professional engagement across multiple platforms. The selection criteria prioritised geographic and disciplinary diversity, genuine contribution to how STEM is taught and experienced in schools, and active public engagement with the professional community. A deliberate effort was made to surface voices from outside the dominant North American and European circuits, and to include both established leaders and emerging voices whose work is not yet widely known outside their immediate professional communities.

Can I hire someone to help my school team implement STEM leadership and culture change?

Jonno White works with school leadership teams to build the communication, conflict management, and decision-making cultures that determine whether STEM education reform actually takes hold. As a Certified Working Genius Facilitator, bestselling author of Step Up or Step Out, and experienced school leadership facilitator with a 93.75 per cent satisfaction rating at the ASBA 2025 National Conference, Jonno delivers workshops, executive offsites, and facilitation sessions for school leaders across Australia and internationally. International travel is often far more affordable than schools expect. Email jonno@consultclarity.org to start a conversation.

What are the biggest challenges in K-12 STEM education globally?

The five most significant challenges are: persistent inequity in who accesses high-quality STEM learning, shaped by gender, race, income, and geography; the STEM teacher shortage in nearly every country; a gap between what research says about effective STEM pedagogy and what actually happens in most classrooms; the integration challenge of teaching STEM as an interconnected discipline rather than four separate subjects; and the technology gap, which is both an equity issue about who has access to devices and connectivity, and a pedagogical issue about whether schools are using technology to deepen learning or simply to automate existing poor practice.

Final Thoughts

The 50 voices on this list share something that goes beyond their specific disciplines, methodologies, or geographies. They are united by a conviction that every child deserves access to a genuine STEM education, not a watered-down version designed to keep the bottom of the class occupied while the top accelerates, but a rigorous, curious, creative engagement with science, mathematics, and technology that develops the habits of mind that every human being needs in a complex world.

The gap between that conviction and the reality of most school STEM classrooms is still enormous. The good news is that it is getting smaller, partly because of the work these 50 people have done and are doing, and partly because of the school leaders who are brave enough to take what the researchers are finding and actually implement it, imperfectly and persistently, in the specific communities they serve.

If you lead a school or a school system and you want to build the team culture that makes that kind of persistent, honest, ambitious work possible, Jonno White works with school leadership teams around the world to develop exactly that capacity. As a Certified Working Genius Facilitator, author of Step Up or Step Out, and host of The Leadership Conversations Podcast with more than 230 episodes reaching listeners in more than 150 countries, Jonno brings the same rigour to leadership team development that the thought leaders on this list bring to STEM pedagogy. Organisations consistently find that international travel is far more affordable than expected. Email jonno@consultclarity.org.
