An evaluation published by the Education Endowment Foundation (EEF) has found that introducing more frequent and structured lesson observations – where teachers observe their colleagues and give them feedback – made no difference to pupils’ GCSE maths and English results.
A randomised controlled trial of the whole-school intervention Teacher Observation was conducted in 82 secondary schools in England, which had high proportions of pupils who had ever been eligible for free school meals. In total, the study involved 14,163 pupils – 7,507 pupils (41 schools) in the intervention, and 6,656 pupils (41 schools) in the control.
Maths and English teachers in the intervention schools were asked to take part in at least six structured 20-minute peer observations over a two-year period (with a suggested number of between 12 and 24). Teachers rated each other on specific elements of a lesson, such as how well they managed behaviour, engaged pupils in learning, or used discussion techniques.
The evaluation, which was conducted by a team from the National Foundation for Educational Research (NFER), found that Teacher Observation had no impact on pupils’ GCSE English and maths scores compared to those of pupils in control schools (effect size = -0.01).
