Mathematical, Interactive Exercise Generation from Static Documents

We present an exercise description language suitable for the representation of interactive exercises which involve mathematical entities, and have complex structures. One of the goals of the language is to provide primitives for support of interactive environments where adaptive presentation of steps and feedback is required. Using this scheme, exercises can be generated from static documents, in what can be seen as a layered scheme: the interactivity layer is applied over the static layer, yielding an interactive version of the content. This significantly speeds up the authoring process, makes the document management process easier, and helps in reusing the document. We believe that the information model presented in this paper, as well as the proposed way of deployment, may provide grounds for new extensions of today’s standards helping to overcome some of the limitations that they currently have.
