Mind the Gap: Making Education Work Across the Globe

On this episode of Mind the Gap, Tom Sherrington and Emma Turner are joined by Craig Barton - maths teacher, podcaster, and co-founder of Eedi - to discuss his ambitious new project: a series of 16 short books, each exploring a single, highly specific element of classroom practice. Drawing on three to four years spent visiting schools and observing hundreds of lessons, Craig explains the thinking behind the project and the principle that every idea included had to be seen working successfully in multiple classrooms. The conversation dives deep into practical teaching techniques, from mini whiteboards and checking for understanding to do-nows and the importance of gathering reliable data about what pupils actually know. Along the way, Craig shares the small but crucial routines that make these strategies effective in practice and reflects on why seemingly simple classroom tools often require careful thought, structure, and purpose to work well. Towards the end of the episode, Craig also delves into the research project his company Eedi did with Google and AI, and its implications for that technology in teaching and learning.
Craig Barton has been teaching maths since 2004, and in 2009, he became the Secondary Mathematics adviser for the Times Educational Supplement (TES). He is the creator of the popular mrbartonmaths.com website and blog, which provides free resources to teachers and students all around the world. Craig also hosts the Mr Barton Maths Podcast. He is the co-creator of Diagnostic Questions, a formative assessment website hosting the world's largest collection of high-quality maths diagnostic multiple choice questions, which aims to help students and teachers from all around the world to identify, understand and resolve key misconceptions. More recently he has created the websites variationtheory.com, ssddproblems.com, and mathsvenns.com, with millions of teachers from across the globe sharing high-quality resources based on ideas from Craig's books. Those books include the recently released Tips for Teachers guides, which you can find at https://tipsforteachers.co.uk/books/

On this episode of Mind the Gap, Tom Sherrington and Emma Turner are joined by Alex Fairlamb and Rachel Ball, co-authors of The Scaffolding Effect, to explore what scaffolding really is (and isn’t) and why it has become such a pivotal idea in the move from “differentiation” to adaptive teaching. They discuss the research roots of the term, the practical reality of “knowing–doing,” and the central challenge that scaffolds must be temporary - designed to be removed through gradual release and guided by sharp checks for understanding. The conversation digs into common pitfalls (from “impermeable skins” of apparent progress to students becoming dependent on writing frames), debates the role of formulaic writing structures, and shows how scaffolding looks different across subjects and phases, including strategies involving reading, writing, retrieval practice, explanations, practical subjects, even homework. Packed with concrete examples and implementation-minded advice, this is a highly usable episode for teachers and leaders who want to support pupils towards real independence.

On this episode of Mind the Gap, Tom Sherrington and Emma Turner are joined by Sam Crome, teacher, leader and author of The Power of Teams, to explore what it really takes to build teams that thrive in schools. Sam reflects on why so much leadership development is still overly individualistic, and shares the practical principles behind strong teams - belonging, alignment, purposeful operations, healthy dynamics, and deliberate development - alongside the habits that make meetings genuinely productive rather than performative. The conversation also draws on Sam’s recent move from secondary leadership into an interim primary headship, teasing out what changes (and what doesn’t) when a “team” becomes a small, agile staff group who can try, refine, and embed improvements at pace. Along the way they discuss cross-phase transition and why primary pupils’ appetite for responsibility and leadership is often underused in Key Stage 3, the “tyranny of the first response” in group discussions, and how simple structures (like paired talk) can surface quieter expertise and build trust for honest, high-challenge conversations.

Sam Crome is currently Interim Headteacher at a primary school in Surrey. He also serves as Director of Education, Mission and People for Xavier Catholic Education Trust, providing both strategic vision and planning, alongside day-to-day school support, so that all children and staff can flourish. Sam is convinced that teams are the way to improve our workload, productivity, professional learning, performance, and the joy we can experience at work. His interest in teams led him to write the book The Power of Teams. Find Sam at https://samcrome.com/

On this episode of Mind the Gap, Tom Sherrington and Emma Turner welcome back Dr Carl Hendrick - writer, researcher and relentless “research distiller” - for a wide-ranging conversation about what the educational research can (and can’t) tell us, and how ideas mutate as they travel through schools. Starting with Carl’s monthly research round-ups and emerging areas like pre-questions (“pre-trieval”), they dig into a lively debate about the replication of the original scaffolding study and what that means for teachers: why learning science is probabilistic, why single studies shouldn’t become dogma, and how “evidence-based” can be misapplied in crude tick-box ways. From there, Carl makes the case for thinking less about “teaching” as an all-purpose term and more about instructional design - the alignment of curriculum, instruction and assessment - and introduces Herbert Simon’s idea of instructional invariants: the conditions that must hold for learning to happen (working memory limits, attention, cumulative knowledge and prerequisites). Along the way they tackle the “lethal mutations” of retrieval practice, the expertise required to design coherent curricula (and why most teachers shouldn’t be expected to do it all), and the implications of AI for homework, assessment and the future of curriculum design.

Carl Hendrick is an internationally recognised expert in the science of learning and instructional design. He is a professor at Academica University of Applied Sciences in Amsterdam and leads research projects that bridge cognitive science, educational psychology, and classroom practice. Carl’s work focuses on helping teachers and school leaders apply robust, evidence-based strategies - such as retrieval practice, spacing, and explicit instruction - to improve student learning. He has co-authored several influential books, including How Learning Happens and Instructional Illusions, and regularly advises schools and organisations on implementing research-informed approaches.

On this episode of Mind the Gap, Tom Sherrington is joined by Dr Simon Breakspear - educational researcher, author, and system leader based in Australia - for a wide-ranging conversation about how improvement actually happens at scale. Together they explore Simon’s distinctive role working across classrooms, schools, networks, and entire systems, and why sustainable change depends less on policy mandates and more on relationships, trust, and practical tools that respect teachers’ limited bandwidth. The discussion digs into two of Simon’s best-known ideas: pruning - a disciplined approach to strategic subtraction that tackles overload and “additivitis” - and Teaching Sprints, a short-cycle, evidence-informed model for collective professional learning that prioritises deliberate practice over sprawling initiatives. Moving fluidly between the macro view of systems and the micro detail of meetings, habits, and classroom routines, this episode offers a clear-eyed account of how leaders can reduce noise, focus effort, and create the conditions for meaningful, long-term improvement.

Dr Simon Breakspear is a researcher, advisor and speaker on educational leadership, policy and change. Simon develops frameworks and tools that make evidence-based ideas actionable and easy to understand. Over the last decade his capability building work has given him the opportunity to work with over 100,000 educators across more than 10 countries. Simon is an Adjunct Senior Lecturer in the School of Education at UNSW. He serves as an advisor to the NSW Department of Education and sits on an expert steering committee for the Australia Institute for Teaching and School Leadership (AITSL). Simon received his BPsych (Hons) from UNSW, his MSc in Comparative and International Education from the University of Oxford and his PhD in Education from the University of Cambridge. Simon began his work in education as a high school teacher.
