The Role of Tool and Teacher Mediations in the Construction of Meanings for Reflection
Healy, Lulu
International Group for the Psychology of Mathematics Education, 28th, Bergen, Norway, July 14-18, 2004
This article reports on a study aiming to design learning systems in which students' knowledge of reflection is brought closer to institutional knowledge of this isometry and to compare how their activities shape and are shaped by different forms of mediation. It presents descriptions of interactions of groups of students (aged 12-13 years) with two computational microworlds, based on either dynamic geometry or multiple-turtle geometry, during attempts to construct and use a tool for reflections and considers how the tools of the microworlds along with the instructional approach adopted by the researcher were important in mediating the passage between meanings emphasizing reflection as property and those emphasizing reflection as function.
