Book excerpt: Combining classic articles that have been key markers in recent debates with some new material, this book addresses the problems involved in educational research and the issues surrounding its contribution to policymaking and practice. The authors examine the diverse approaches within qualitative research and address some of the key areas which have attracted criticism. They consider what role research should play and examine the case for randomised controlled trials and for action research. The book is suitable for any undergraduate or postgraduate student concerned with educational research methodology, as well as those focusing on educational policy and practice, and students doing PhDs and EdDs.
