Using Competencies to Search for Suitable Exercises

With the massive use of the Web, numerous sites proposing exercises have appeared. The great difficulty for teachers and students is to find suitable exercises for the discovery of a new subject, training, revision or evaluation. On the basis of the teachers´ reflections, on how they determine the exercises which they need, we extracted the characteristics which seemed to us the most important and we propose modalities of exercise description. These descriptions are based on a taxonomy supplemented by a graph of competencies and sub-competencies. We conceived tools to create a base of exercises implementing these descriptions. We developed interfaces allowing the teachers to store exercises, to find them by following several ways of searching for exercises and to create interactive worksheets.
