David Didau is Senior Lead Practitioner for English at Ormiston Academies Trust and a freelance writer, blogger, speaker, trainer and author. He started his award-winning blog, The Learning Spy, in 2011 to express the constraints and irritations of ordinary teachers, detail the successes and failures within his own classroom, and synthesise his years of teaching experience through the lens of educational research and cognitive psychology. Since then he has spoken at various national conferences, has directly influenced Ofsted and has worked with the Department for Education to consider ways in which teachers' workload could be reduced.
