The very nature of wiki-based collaborative writing around a topic-related content is the interaction of wiki functionality, content, and collaborative learning, and how the functionality is used to create the content collaboratively. This way of looking at wikis provides a theoretical model that helps researchers and educators to identify a number of category actions that can be carried out on wikis when students perform collaborative writing activities. This work aims at using the proposed model to evaluate the impacts of MediaWiki on collaborative writing among students in teacher education. Pedagogical implications are drawn from the results and future research actions are envisaged to enhance the quality of wiki-based collaborative writing in teacher education.
