RESUMO
Teaching improvement workshops are most effective when they engage teachers actively in practice teaching, particularly when the teaching situation is similar to the actual one to which the teachers will return. Teachers, however, often find such involvement threatening. In this paper we describe a 3 h workshop which succeeds in overcoming teachers' reluctance to participate in situations that are relevant to their real teaching problems, students, and subject matter. The most exciting outcome, in our view, was teachers' increased sensitivity to the limitations of their teaching approach and their increased awareness of the role of their concept of teaching in shaping their teaching strategies. Weaknesses of the workshop include its dependence on the skills of a group director, the tendency of the group to seek a single right answer instead of exploring alternatives and the usual danger of role rigidity which troubles all role enactment procedures.
