ERRR #070. Gwyn Ap Harri on Impactivity, Leadership, and Smoothly Unfolding Sequences

·1 hr 38 min·5 clips

Gwyn Ap Harri reveals why classroom feedback isn't the biggest factor in student success—it's what happens before kids even arrive.

Education Research Reading Room is a podcast for educators hosted by Oli Lovell. This episode was unplanned: Lovell had finished recording a conversation with XP School co-founder Andy Sprakes (Episode 69) and was packing up when Gwyn Ap Harri came into the room. After 15 minutes of informal conversation, Lovell asked if he could record, and they talked for five hours. This episode contains approximately the first hour and a half. XP School is a state school in Doncaster, England, co-founded by Gwyn and Andy Sprakes, which operates on an expeditionary learning model derived partly from EL Education and informed by a radical rejection of conventional school structures. Gwyn is described as a first principles thinker — someone who strips away assumptions and asks why things are done a certain way rather than accepting convention. The conversation enters directly into a discussion of character education and why, in Gwyn's view, the most important things affecting student outcomes are not what John Hattie's extensive quantitative meta-analyses identify as having the greatest effect size. Gwyn does not dismiss Hattie's findings but argues that they measure what happens in classrooms after the more fundamental conditions of culture, character, trust, and leadership have already been set. The episode covers Gwyn's personal upbringing, the founding philosophy behind XP School, leadership culture within the school, and the concept of impactivity — creating the conditions in which meaningful learning can occur rather than just delivering instruction. The conversation is described as ranging over solving a Rubik's Cube and various other tangents as well as the central themes.
