Study 8 was designed to gather data using a focus-group interview format among the same teachers who participated in the classroom research. As one of the hoped outcomes of this research project was the enrichment of my colleagues’ and my own practice, I found it important to choose this format instead of one-on-one interviews, as it involves “participants thinking together, inspiring and challenging each other, and reacting to the emerging issues and points” (Dörnyei, 2007, p. 144), which can, as I see it, contribute to professional development. The following section details the participants and setting of the pilot study and the main study and the methods of data collection and analysis in both cases.
