In our professorship 'Learning Strategies' of the Fontys Secondary Teacher Training College Tilburg, we stress the importance of practitioner research for the professional development of teachers. To investigate our own beliefs, we started a project in which teachers learned to do practitioner research in their own schools. There were two questions we were interested in:
1) Which elements of the program are suitable to help teachers to learn do their own practitioner research?
2) What knowledge do teachers create in doing practitioner research?

Several authors mention the benefits of practitioner research performed by teachers (Loughran et al, 2004; Zeichner & Noffke, 2001; Cochran-Smith & Lytle, 1999; Cochran-Smith, 2005; Huberman, 2002; Anderson & Herr , 1999; Robson, 1993, 2002; Onstenk, Kallenberg & Koster, 2007). Doing their own research would increase their professionalism as teacher. Although the relevance of practitioner research is stressed by many authors, not many teachers in the Netherlands are already actively doing practitioner research. Among other causes, the lack of experience in how to do practitioner research might be a barrier.

We developed a program for teacher practitioner research, consisting of seven group sessions. In each session, attention was paid to theoretical backgrounds (formulation of a research question, choosing methods, obtaining and analyzing data, reporting on the findings) and to practical implications (participating teachers were advised by each other and by the supervisor). Most teachers worked together in a couple on their research project.
The supervisor kept notes about difficulties and experiences of the teachers during the process and interviewed the teachers after they finished their research project.
The answers to our research questions are:
1) The theoretical parts of the program were necessary for teachers to obtain knowledge about the (systematic) approach of research. The practical help of the supervisor was crucial during the process as the teachers were insecure about applying their newly obtained research knowledge in practice and needed help to do so.
2) Teachers obtained knowledge about performing practitioner research as well as knowledge about the problem they investigated in their school practice. Furthermore, they mention personal benefits such as 'another look at my profession', 'renewed motivation' and 'new insights'.
