What alternative models of lesson observation do you use in your school?
Teaching is a team sport. No teacher can solve complex classroom problems on their own.
One of my favourite books is published by Dr Matt O'Leary, Classroom Observation (2013 and 2020). It's an important read for anyone responsible for whole school teaching and learning.
O'Leary first references another one of my favourite pieces of research; Professional Capital, written by Andy Hargreaves
