Abstract

Many scientific fields use diagrams to teach or to illustrate new ideas. Unfortunately, students are not able to efficiently follow the construction of this diagram and to draw them on their notes. This has a huge drawback: when, later, they must read those notes they often lack the true order of their construction which can lead to a misinterpretation.

In searching for a way to overcome this difficulty, we have found the JSXGRAPH Javascript library which not only help to draw those diagram but also to animate them. Unfortunately, the difficulty of the langage, due to the necessity to capture the different events which should be listen before to initiate a movement, forbade the most part of the scientist to construct the diagram of their dreams.

To try to overcome at least a little this difficulty, we have tried to construct JDE (Jsxgraph Dynamic Editor) a new editor which could facilitate not only the static conception of a diagram but which can cope also with some of its dynamical caracteristics.
