Exploratory activities with dynamic geometry environment in axiomatic geometry
Page: 1540
In this study, I designed and implemented an instructional sequence of exploratory activities using a Dynamic Geometry Environment (DGE) in an axiomatic geometry course. The tasks in the sequence aimed at providing students with opportunities to encounter cognitive conflicts between their prior knowledge on Euclidean geometry and new observations on non-Euclidean geometry. However, some did not appear, some did appear and students recognized them, but could not resolve or just passed by. The conflict between what I intended in designing tasks and what I found in student responses seems to result from several aspects of design and implementation of the tasks.
