Teachers' interactions and their collaborative reflection processes during peer meetings.

Teachers' reflections are often narrowly focused on technical questions ('how to') and less on the underlying moral, political and emotional aspects of their functioning. However, for a better understanding of teaching practice it is important to uncover beliefs and values that usually remain implicit. Meeting with others is considered crucial for enhancing the quality of teachers' reflections.

Portfolio as a tool to stimulate teachers' reflections.

Portfolios are increasingly being used to stimulate teachers' reflections. Frameworks for reflection on teaching often emphasize competencies and behaviours. However, other aspects of teacher functioning are also important, such as the teaching environment and individual teachers' beliefs, professional identity and mission.

Participants' opinions on the usefulness of a teaching portfolio.

Background: Whether teaching portfolios achieve their aim of stimulating teachers' professional development is favourably affected by the incorporation of a balanced structure and effective social interactions, such as coaching. We explored teachers' experiences with a teaching portfolio that was structured by teaching roles, portfolio assignments and conversation protocols. The related social interactions consisted of meetings with peers and personal coaches.
