Current in-service education and training programmes (INSET) are often found to be unsatisfactory due to the fact that they do not provide the teachers with opportunities to be actively involved in their development and to reflect on their teaching experiences. This study presents an INSET programme in which Turkish EFL teachers were provided with relevant theoretical knowledge along with guidance for research, reflection, and collaboration. Results of the study showed that although teachers faced difficulties in conducting and reporting their research, the programme had a positive impact on their professional development. Thus, a research-oriented programme of this kind may help to resolve the problems and difficulties associated with INSET programmes in general.
