Is collaborating on-line more productive than collaborating face-to-face? This case study is an exploration of the effectiveness of face-to-face and computer supported collaboration. More specifically learner attitudes towards the use of on-line and on-site collaborative learning within an undergraduate course on integrating technology into the classroom at Concordia University are explored. Learner reflections kept throughout the semester is analyzed to determine whether certain elements of collaboration, namely (a) efficiency, (b) group management, and (c) task process, are more productive within an on-line or on-site collaborative learning environment. Findings suggest that learners do perceive that some elements of collaboration are best suited to an on-line learning environment while other elements are best suited to an on-site learning environment.
