This study investigates the design of a role structure to engage undergraduate students in collaborative knowledge construction. A total of 72 students of an Instructional Design course were divided into 12 small groups, among which six roles of Starter, Supporter, Arguer, Questioner, Challenger, and Timer were assigned respectively. Group discussions of eight learning themes were recorded, which included approximately 1500 lines of messages. Taking group discussion as the unit of analysis, a two-dimensional coding scheme was developed to discover the extent to which the designed role structure facilitated the modeling of the group cognitive processes. The findings suggest that the role structure design supports the students in collaborative problem solving by modelling the joint collaborative activities and group cognitive processes. Therefore, mapping the designed roles of related cognitive components in a group discussion may develop group cognition in a collective problem-solving process.
