What do effective teachers do and what are the benefits of pupils attending grammar schools?

These are just two of the questions posed in our 49th podcast interview with Dr Sam Sims who is a quantitive education researcher working at the Institute of Education which is part of UCL University.

In this 22-minute podcast, listen to Sam and Teacher Toolkit founder, Ross McGill explore why Sam spends his working days crunching data and hear him offer research-based top tips to policymakers, including why Sam doesn't want more grammar schools in the UK.

We also discuss the topics covered in Sam and Professor Becky Allen's book, 'The Teacher Gap' unpicking what effective teachers do and what their research suggests, reflecting on the vast differences in working conditions across schools.
