As a sociology graduate, I have a great deal of respect for Frank Furedi, but I think he's a bit confused about the practical applications of evidence in schools ("Teaching is not some kind of clinical cure", Comment, 4 October). He is right that randomised controlled trials are too clinical for a field in which variables are complex and unpredictable. But he is wrong to conclude that there is no place for evidence-based practice. The experience of leaders, teachers and students in schools such as mine - which are part of collaborative networks such as Whole Education or work with bodies such as the CfBT Education Trust - is that there is much to be learned from "what works" in other contexts, and that experiments based on those observations are highly effective and economical.
