Resources and inquiry-based teaching - the role of in-service math teacher schemes

This research analyses the interaction of 62 in-service maths teachers with a resource called Study and Research Path (SRP). The SRP are resources developed to carry out inquiry-based teaching in the frame-work of Chevallard's anthropological theory of didactics. The aim of the work is to describe the teacher's schemes in two situations: study and analyse the SRP and then organise a teaching plan. The schemes generated in each situation are described from the theory of conceptual fields and the instrumental ap-proach, analysing the individual written responses of teachers to both situations. The work shows the diversity and richness of the instruments generated by teachers and allows us to understand their difficul-ties in developing inquiry-based teaching.
