Already in common use outside the educational arena, wikis are rapidly moving into education as a form of learner communication and expression, and as a means to facilitate collaboration and working in groups. Many uses of wikis in formal education have been outlined by scholars and practitioners mainly focused on the students' perspective. However, further investigations are needed on how teachers are actually using this tool to support the design and development of educational materials, as well as the evaluation of both individual contribution and active participation to collaborative learning projects. This book provides a valuable tool and a source of knowledge for all those involved in enhancement of formal and informal learning both in higher and adult education.
