A European project for professional development of teachers through a research based methodology: the question arisen at the international level, the Italian contribution, the knot of the teacher-researcher identity

The European project PDTR, which this paper deals with, is aimed at the development of research based methodologies for teacher training to promote new classroom approaches in the sense of PISA competences. After a short description of the Project, we present in some details the cultural choices, the work methodology and the outcomes of the Italian teams. Some reflections are made about the main problems involved, in particular on the intense attempts to clarify the meaning of the figure of the teacher-researcher, the true core of the Project. In a few final remarks we discuss the validity and the potentialities of the Project.
