Group project work is a common study format in tertiary education. It aims to induce collaborative learning by enabling group members to explore a specific topic. Internet tools such as e-mail, chat groups, and discussion forums assist group members in coordinating project work. In recent years, Blackboard’s groups facility has become widely used to support group work because it enables file exchange, e-mail, and discussion forums for study groups. However, the potential role of these tools in collaborative writing is limited because they do not promote the use of a single shared document. A collaborative technology, wikis, offers an alternative, by providing a shared document that any participant can access and edit. The promise of wikis is better collaboration, leading to higher productivity or better quality of the work product. This paper reports findings from an exploratory study comparing student groups using a wiki application in collaborative work with groups using Blackboard groups in a graduate course on systems integration. Our study suggests that the use of wikis improves group interaction and reduces the individual work effort to create a joint work product, without lowering the performance of group members. However, our study also finds that students will often stay with a less user-friendly technology if they are more familiar with it.
