Quality issue in the design and use of resources by mathematics teachers

摘要

The profusion of resources, mostly on the Internet, makes the issue of their quality more and more pressing. Teachers often find themselves unable to choose from among them those that would be the most relevant to their educational goal and to the context of their classes. In our previous work, we claimed that acquiring resource analysis skills is one of the keys to the teachers’ professional development supporting the integration of dynamic geometry systems. Based on this assumption, we have designed a quality questionnaire for the i2geo repository aiming at framing the analysis of available resources by the platform users. The research reported in this paper, which is a continuation of this work, explores the way the quality criteria are taken into account in the design and use of resources by members of the community that has emerged around the repository and sheds light on possible evolutions of teachers’ and teacher educators’ professional practices due to their involvement in the resource quality evaluation.
