Evidence suggests that cooperative learning fosters students' ability to work with others and may lead to better cognitive outcomes and higher achievement. In this article, we describe a wiki-based teaching approach which promotes, within Portuguese speaking countries, student collaborative production of learning materials related to Medical Informatics. To this end, a MediaWiki platform (http://aprendis.gim.med.up.pt) was made available. The type of activities developed are described and a set of statistics from wiki activity is presented. The potential of this platform for student’s engagement is discussed revealing that this approach fosters collaborative learning and allows for continuous improvement of teaching materials.
