Ross McGill really needs no introduction. Through his alter ego Teacher Toolkit, Ross is something of a publishing powerhouse, with a quarter of a million followers on Twitter - by far the biggest following of anyone in education. A teacher and school leader with decades of experience, Ross now works as a consultant and has worked in over 200 schools, colleges and universities across the UK and around the world. Ross also has one the most influential education blogs on the planet, with around 12 million hits. He has also published five books, the most recent being Mark Plan Teach 2.0. This is a fascinating, wide-ranging conversation in which we discuss the perils of EduTwitter; the way in which teaching is becoming a much more sure-footed, evidence-informed profession; and the trouble with Ofsted, an organisation Ross refers to as the Grim Reaper. Here's a link to the verbal feedback report and toolkit Ross developed alongside Mark Quinn at UCL Institute of Education: https://www.ucl.ac.uk/widening-participation/teachers-and-education-professionals/teacher-research-projects/verbal-feedback-project. And here's a blog by Mark Quinn outlining the key findings: https://blogs.ucl.ac.uk/ioe/tag/verbal-feedback-in-schools/. The Rethinking Education podcast is hosted and produced by Dr James Mannion.
