Abstract Computer Supported Cooperative Work (CSCW) combines the benefits of collaborative learning with computer supported technologies. However, it is important to fit the methods, how CSCW systems are exploited in education, to the educational goals. It can not be taken for granted that students will interact simply because the system in use makes it possible. PeerWise is a CSCW system that allows students to create and answer multiple-choice questions collaboratively. The purpose of this work was to find out how students find the usage of PeerWise and study the behavior of students using PeerWise. Also, the possibility for recognizing faulty questions automatically was studied. PeerWise was used in four courses during 2009 at the Helsinki University of Technology. Students were clustered based on their behavior in PeerWise and feedback of using PeerWise was collected after the courses. The reliability of quality ratings given to questions was tested by having a group of experts rate the same questions than students. In order to recognize faulty questions, a set of questions was classified with Naive Bayes classifier. This way, the results of classifying questions purely with methods available
