  1. Hilaire Fernandes, Stéphane Ducasse, and Thibault Caron. Dr Geo II: Adding Interactivity Planes in Interactive Dynamic Geometry. In Proceedings of 5th International Conference on Creating, Connecting and Collaborating through Computing (C5 2007), p. 153—162, IEEE Computer Society, 2007. DOI 

    Interactive geometry environments support the creation and exploitation of interactive geometric sketches. However, such environments are often driven in a rigid manner, following a well specified construction path. This rigidity is not always compatible with: i. the internal cognitive representation of the learner about the geometric domain and ii. the way a geometric sketch is used in a paper-pen environment. This rigidity is therefore a source of internal tension for the learner and it can reduce the pedagogical added value of the interactive geometry environments. We think additional interactive planes to manipulate a geometric sketch differently can help the learner. We have developed DR. GEO II, an interactive geometry framework that is able to receive additional interactive planes such as a free sketching and a command-based one. We have experimented it in a junior high school class and we report here our first results.
