"The topic is absolutely central to the current debate of teacher professionalism and reform. The authors dig beneath the surface and provide insights and clarity about current reform attempts." — Michael Fullan, University of Toronto"The authors provide both a conceptual analysis of what is entailed by a professional and a bureaucratic view of teaching, and have case material which illustrates what actually happens when these differing approaches to teachers' work (or some mixture of these approaches) are tried out in school districts. We need more of this kind of conceptual work." — Alan R. Tom, University of Arizona
