Daisy Christodoulou: I'm saying knowledge is good

In this episode, we speak again to John Jerrim. He is Professor of Education and Social Statistics and Director of the Quantitative Social Science Research Centre at UCL Institute of Education. Last year, John was Chalk & Change's first interviewee, discussing his special subject: international tests and what we can and can't learn from them. By request, he returned to discuss the results of the 2025 PISA tests which were released in early September. We discussed what had surprised him, what trends are emerging, and how robust these results are.

In this episode, we’re talking to Lucy Crehan. Over a decade ago, she waved goodbye to science teaching in London, and set out to visit the highest-performing education systems in the world. Her book, Cleverlands, describes what schools are really like, in countries as diverse as Finland, Canada, Singapore and Japan. Today she’s one of the world’s foremost experts in comparative education, and has supported national reforms in countries including Brunei, Guyana, Myanmar and the Czech Republic. Most recently she’s been working on curriculum reform in Northern Ireland, and leading the work of the Centre for Education Systems. We discussed: What inspired her round-the world tour of high-performing education systems Why Finnish schools as the best option (for students and parents) The problems posed by the academy system What classrooms across high-performing education systems have in common Why it’s hard to make good policy (outside Singapore) Leading the Northern Ireland curriculum review Lucy’s ability to combine thoughtful analysis with first-hand experience of a diverse range of education systems made this a particularly fascinating conversation.

"You can have a lovely building but if the teaching's no good, the thing's not going to work." In this episode, we speak to Sir Dan Moynihan, CEO of the Harris Federation. Beginning as an economics teacher in Tower Hamlets in the 1980s, he became a head teacher in 1999, and the principal of what was then the Harris City Technology College in 2005. The Harris Federation was founded the following year, and now runs 55 schools. He has spent twenty years overseeing its growth. We discussed: London schools in the '80s: " Nobody could imagine that it was as bad as it was back then." The difference the Education Reform Act made to leading schools How he turned around his first school: "Sounds obvious now." Why he moved to Harris City Technology College and how he began building a trust How Harris balances prescription and autonomy in school improvement The role of the the headteacher: "You can have a hero head - the problem is that's not sustainable." How he keeps improving, and what he's working towards now Dan's career encapsulates the dramatic improvements in English schools, and the underlying changes which have made them possible. The authority with which he can speak about turning around one school - and leading fifty - made this a particularly interesting interview.

"I hate the idea of settling for mediocrity." In this episode, we talk to Baron Gove of Torry. Entering Parliament in 2005, as MP for Surrey Heath, Michael Gove was Shadow Education Secretary from 2007, and Secretary of State for Education from 2010 to 2014. His subsequent government roles included being Minister for Justice, and Secretary of State for the Environment, Food, and Rural Affairs. Standing down as an MP in 2024, he now edits The Spectator. His tenure proved controversial among teachers, and consequential for the education system. As Daisy Christodoulou put it, he "set the contours for the next half century." In this interview, I wanted to understand the contours he aimed for, how he sought to pursue them, and what he had learned from the experience. We discussed: His diagnosis of the challenges facing English schools in 2010 How he sought to make the Department for Education deliver his agenda The curriculum review, and why he became closely involved in it The balance between autonomy and prescription The goals of the academy programme What he took with him to the Ministry of Justice and DEFRA His reflections on the process, and his approach Unbowed in his belief that "knowledge should not be restricted to an elite, and that the best that has been thought and written belongs to everyone," he reflected also about how picking his battles, and "a greater degree of imaginative sympathy for people on the other side" might have helped.

"You can learn a great deal from Finland, but you have to get into a time machine." In this episode, we speak to Tim Oates, CBE. Tim was an education researcher and evaluator of youth training schemes, then worked at the Qualifications and Curriculum Authority, before joining Cambridge Assessment in 2006, where he was the Group Director of Assessment, Research and Development for almost 20 years. He’s currently a fellow of Churchill College, working with governments around the world on curriculum assessment. Most recently that’s included the curriculum review for Northern Ireland and work in Flanders. His areas of expertise include: Assessment and international comparison, The role of textbooks, The successes of the Finnish education system and otherwise; and, What makes an effective curriculum. Between 2010 and 2013, he chaired the expert panel reviewing the national curriculum in England. We discussed: How confident we can be that students in England are learning more Why geography responded well to the National Curriculum Review, and how primary English became overloaded How he came to chair the expert panel for the National Curriculum Review Why reform of the geography curriculum worked so well The difference between borrowing policies and learning from other countries What's working - and not - in Estonia, Finland, Singapore and Sweden The "very un-British idea" that we might be doing something right in England Tim brought to bear an astonishing depth of experience and wisdom.
