Feedback can promote teacher-student relations and student academic involvement, performance and self-regulation. However, some research indicates that teachers do not always employ feedback effectively. There is a need to promote teachers' appropriate use of feedback in the classroom. We describe a long-term workshop designed to enhance teachers' knowledge and skills in the use of feedback strategies, and appreciation of the importance of feedback. Twelve teachers participated in the workshop. Observations as well as teacher reports indicate that participation in the sessions and the follow-up classroom application enhanced teacher involvement, knowledge, competencies and positive feelings in the use of feedback strategies. A workshop for teachers that has specific objectives on feedback strategies, is presented along a school year, and involves reflective sessions intertwined with classroom application work, can effectively promote participants' involvement, knowledge and competencies in the use of feedback, as well as their outlook toward the importance of these strategies.
