Becoming Critical [PDF ebook] 
Education Knowledge and Action Research

First published in 1986. There is now a growing movement to extend the professionalism of teachers by providing them with greater opportunities to engage in curriculum theorizing and educational research. The purpose of this book is to offer a rationale by outlining a philosophical justification for the view that teachers have a special role as researchers and that the most plausible way to construe educational research is as a form of critical social science.
