Abstract
In previous MERGA conferences, we have reported on our project to implement Polya-type problem solving in the main curriculum of one high achieving secondary school and the follow-up project to diffuse the innovation to a wider range of secondary schools. We used design experiment as the methodology in both of the projects. In this symposium, we report on various aspects of this design experiment while it is in progress. The three papers show the vital interactions between the researcher-designers and the teacher-implementers to fine-tune a workable design for each individual school.
