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.
Paper 3: Problem solving task design is not only the design of a non-routine
problem to be solved by the students. Our task design also requires a supporting document, the practical worksheet, which would act as a cognitive scaffold for the students in the initial stages of the problem solving process before they can internalize the metacognitive strategies and automate the use of these strategies when faced with a new problem. A further enhancement of the scaffolding that can be provided by the teacher as she facilitates forty or more students working on the practical worksheet is a set of scaffolding cards. In this paper, we describe the cards and the preliminary use of these cards to facilitate problem solving for teachers in a professional development workshop.
