  #230 HoD Space ep2: Notes in exercise books, Ofsted, and A-level class sizes 09.09.2026 42min

What actually goes in the exercise bookPrompted by a HoD Space member's survey request, Craig puts four options to the community — I do, we do and independent work; I do and independent work; independent work only; or no exercise books at all — and reports where members landed. He sets out why he thinks copying down worked examples is a pace killer and an illusion of understanding, Jo explains why she models on the board but never asks students to copy it, and the two of them disagree about whether key words and definitions have earned their place in the book.2. What the new Ofsted framework means for heads of mathsJo asked HoD Space members for recent first-hand experience of inspection under the new framework, and reports back on what came out of it: deep dives have gone, middle leaders may not be asked to talk about their own department, and questions about the maths curriculum are landing with line managers instead. She and Craig work through what that means in practice — the workload around annotated seating plans, the pressure schools are putting on exercise books, the focus on gaps in Year 7 prior knowledge — and land on the same advice from two directions: make sure the person who line-manages you can articulate what happens in maths lessons and why.3. A-level class sizesA thread from a member who had seen their A-level groups grow turned into the episode's biggest surprise. Jo describes teaching 28 in further maths and hearing from a school with 32 in a room that seats 32, before setting out why this bites from three angles — the head of maths trying to recruit and carrying an ever-larger key stage five, the classroom teacher who physically cannot get round the room, and the student who was told A-level classes would be smaller than GCSE ones. Craig brings in the Campaign for Mathematical Sciences research on the scale of the problem, and Dylan Wiliam's warning that cutting class sizes only improves outcomes if teachers do something different with the time — and if the extra teachers you hire are as good as the ones you have.

Access the show notes here: ⁠https://podcast.mrbartonmaths.com/228-hod-space-ep1-praise-tick-sheets-year-7-sets-first-departmental-meeting/⁠In this episode of the podcast, Jo Morgan and Craig Barton discuss:1. Praise, and the problem of the "invisible pupils"Prompted by a question from HOD Space member Megan, Jo and Craig dig into Pritesh Raichura's seating plan tick sheet — where a teacher aims for 30 to 50 individual praises a lesson — and ask whether that's realistic in a maths lesson built around long stretches of independent practice, before turning to how a head of department supports a teacher who wants to try something like this, and what it would take to roll it out across a team.2. Setting Year 7Jo explains why her school groups new Year 7s using SATs results rather than a baseline test, how two early end-of-unit tests are used to sense-check those groupings, and why keeping the whole business of setting deliberately low-key matters as much as getting the groups right.3. Planning your September INSET meetingJo makes the case that the first department meeting of the year is the most important one you'll run all year, and talks through what goes into hers — from lesson expectations and homework routines to the admin nudges teachers need and the single department focus that will shape the year ahead.

  #222 AI in Education with Becky Allen 13.05.2026 1h 36min

  In this long-awaited sequel (eight years after her last appearance), Craig welcomes back Becky Allen — education researcher, co-founder of Teacher Tap, co-author of The Teacher Gap, and now a consultant to the US-based Alpha School chain — for a deep dive into AI in education, with a particular focus on AI as a personal tutor. Becky is a self-confessed AI optimist who uses LLMs for almost everything (with a fervent endorsement of WhisperFlow voice transcription as a game-changer for giving models richer context). She walks through what she's been seeing inside Alpha School, where students do roughly two hours a day on AI-powered learning apps and spend the rest of their time on project-based learning, sports, and life skills. Her clearest examples of where AI tutoring genuinely shines are in generative prerequisite-knowledge conversations and in forcing students to engage step-by-step with worked examples — pulling them out of the passive eye-darting that kills most textbook learning. From there, Craig walks her through a battery of common sceptical pushbacks (screen time, scalability, Alpha's wealthy demographic, motivation without an audience, the Khanmigo flop, applicability to the Global South, and the future of subject-specialist teachers) and Becky pushes back on each with characteristic nuance. Her core thesis: AI won't transform mainstream schools much — they're too operationally complex to bend — but it will enable a parallel world of micro-schools, alternative provision, and remote subject specialists, particularly for the growing population of persistently absent and home-educated children. The conversation closes with reflections on whether AI will take her own job (and what to advise her children) and a prediction that the most concrete thing AI will fix in mainstream schools is marking.

  #221 Building an AI tutor with Google DeepMind with Bibi Groot (Eedi’s Chief Impact Officer) 06.05.2026 1h 47min

  In this episode of the Mr Barton Maths podcast, Craig sits down with Bibi Groot, behavioural scientist at Eedi, to unpack the rigorous research behind their ed-tech work. Bibi traces her journey from the UK's Behavioural Insights Team — where she applied frameworks like EAST (Easy, Attractive, Social, Timely) to public policy — to becoming Eedi's first behavioural scientist after a stint completing a PhD at UCL and having twins. The conversation builds methodically from the fundamentals of randomised control trials (and why they're so notoriously difficult to run well in schools) through the headline results of Eedi's two-year, 20-school RCT showing that students using the platform gained the equivalent of two to four extra months of progress, before diving into the much-publicised Google DeepMind collaboration. That study, run with LearnLM and a human-in-the-loop safety net, found that an AI tutor matched a human tutor on immediate question success and actually outperformed humans on short-term transfer questions — likely because the AI was relentlessly Socratic where time-pressured human tutors tended to short-circuit students' metacognition. Bibi closes by previewing Eedi's much larger four-arm follow-up trial (running until July 2026) testing whether deep student context beats strong pedagogy alone, plus exciting new pilots bringing DQR and WhatsApp-delivered AI tutoring to learners in Guyana, India, and Sub-Saharan Africa.

  #220 AI in Education with Dan Meyer 29.04.2026 1h 26min

  A decade after his first appearance on the podcast, Dan Meyer returns to discuss the intersection of AI and mathematics education. Now leading AI feature development at Amplify (which acquired Desmos), Dan brings a uniquely balanced perspective—simultaneously a critic of AI's most maximalist claims and an active builder of AI tools for the classroom. Craig and Dan dig into three core areas: AI as a personal tutor, AI for teacher professional development, and AI for assessment. Along the way, they explore why AI tutors keep falling short of their hype, what Amplify's "discussion moments" feature reveals about thoughtful AI integration, the realities of the Alpha School model, and the social dimensions of learning that no chatbot can replicate. Dan argues that genuine educational improvement may depend less on technology and more on political solutions like teacher pay, class sizes, and addressing inequality—a sobering counterpoint to the dominant AI-as-saviour narrative. the show notes here: podcast.mrbartonmaths.com/220-ai-in-education-with-dan-meyer/

  #216 AI in Education with Barbara Oakley 18.03.2026 1h 6min

  A long-awaited conversation with Barbara Oakley, distinguished professor of engineering, bestselling author, and creator of the world's most popular online course "Learning How to Learn." Barbara shares her remarkable journey from hating maths in school to becoming a champion of cognitive science-based teaching, and brings her expertise in memory and learning to bear on the rapidly evolving world of AI in education. Across four key areas—personalised tutoring, assessment, lesson planning, and teacher professional development—Barbara offers a refreshingly optimistic yet pragmatic take on how generative AI can support learning, while issuing strong warnings about the dangers of constructivist approaches in an AI-enabled world. She makes a passionate case for testing more (not less), for cognitive realist teaching over student-centred approaches, and for bringing the scientific method into education the way it transformed medicine. The conversation ranges from how AI helps her generate metaphors and surprises in her own teaching, to a fascinating insight into how large language models "grok" patterns in ways that mirror human learning.
