Interpretation of diagrams in dynamic geometry environments
Interpretation of diagrams in dynamic geometry environments
This study addressed the use of dynamic geometry environments in students’ mathematical activity related to proofs and refutations. Using a framework of student interpretation of diagrams, we analysed a task-based interview where a triad of Japanese secondary school students (16–17 years old) tackled tasks related to conjecturing, proving, and refuting using dynamic geometry. Our study suggests that the distinction between perception and relation-oriented interpretations, as well between ‘drawing’ and ‘figure’, can help in deepening understanding of student behaviour when they are using dynamic geometry environments.

Abstract
This study addressed the use of dynamic geometry environments in students’ mathematical activity related to proofs and refutations. Using a framework of student interpretation of diagrams, we analysed a task-based interview where a triad of Japanese secondary school students (16–17 years old) tackled tasks related to conjecturing, proving, and refuting using dynamic geometry. Our study suggests that the distinction between perception and relation-oriented interpretations, as well between ‘drawing’ and ‘figure’, can help in deepening understanding of student behaviour when they are using dynamic geometry environments.
