This extensively illustrated Pocketbook takes a practical approach to classroom observation for professional development purposes. It begins by establishing the reasons for lesson observations, outlining the benefits, and defining protocols. There is a chapter, with clear do's and dont's, on how to become an effective observer. This is followed by a look at different models of observation, starting with the observer as learner, also known as 'the worker bee model'. Then, via paired, peer and trio observations, there is a section on being observed as professional development. Here the observer takes the role of coach. The final model is the performance management/Ofsted model, with the observer as assessor or judge. A section on how to give supportive verbal and written feedback leads to a closing chapter on personalising classroom observation for individual departments or schools, touching briefly on pupil observation. Roy Watson-Davis, author of this title and of the "Creative Teaching" and "Form Tutor's Pocketbooks", is an Advanced Skills Teacher with hundreds of observations and feedback sessions to his name. He trains teachers on effective observation and is experienced in developing whole school protocols and policy.
