Developing a Framework for Characterizing Student-Created Diagrams in Dynamic Geometry Environments

• In Event: Deepening Students' Mathematics Reasoning and Engagement

Abstract

Dynamic geometry environment (DGE) offers a wide range of tools for its users to create and interact with geometry diagrams. In this paper, I propose a framework to characterize the geometry diagrams learners create in DGEs. This framework considers a learner’s approach to creating a geometry diagram (i.e., perceptual-based, measurement-based, construction-based, and transformation-based), the driving force that guides the learner’s specific actions in a DGE (i.e., tool-driven, and property-driven), and constraints in the resulting diagram (i.e., drawing, underconstrained, overconstrained, and appropriately constrained).
