Transfer is required in nearly every activity of problem solving. It spans from transferring procedures within a finite set of similar "end of the chapter problems" to applying problem solving strategies in completely unfamiliar problems. Students' self-perceptions, in the context of problem solving and learning, influence the success of instruction promoting transfer. Hence, teachers have to attend to such self-perceptions. We conducted a cooperative inquiry workshop to support teachers who modify their instruction in problem solving to better achieve transfer goals. As part of the workshop, the teachers raised the need to develop a questionnaire examining students' self-perceptions in the context of problem solving and learning in physics. The development of the questionnaire was supported by educational research, in a manner reflecting the teachers' motivation and time limits. In this paper, we describe the process of developing the questionnaire, present findings from a validation analysis of the questionnaire, and discuss its role in the teachers' professional development.
