Providing a Foundation for Deductive Reasoning: Students' Interpretations When Using Dynamic Geometry Software and Their Evolving Mathematical Explanations.
Peer reviewed Peer reviewed
Jones, Keith – Educational Studies in Mathematics, 2000
Reports data from a longitudinal study of 12-year-old students' interpretations of geometrical objects and relationships when using dynamic geometry software. Focuses on the progressive mathematization of the students' sense of the software, examining their interpretations, and using the explanations that students give to the geometrical…

Dynamic Geometry Environments as a Source of Rich Learning Contexts for the Complex Activity of Proving.
Peer reviewed Peer reviewed
Laborde, Colette – Educational Studies in Mathematics, 2000
Attempts to develop a global discussion about the roles of dynamic geometry systems (DGS) by addressing four points: (1) the variety of possible contexts for proof in a DGS; (2) the dual nature of proof (cognitive and social) as reflected in the "milieu" constructed around the use of a DGS; (3) from observing to proving; and (4) overcoming the…
