With the question still open, this paper examines the use of this technology in fostering critical thinking and other higher-order learning and team-building skills, in the context of two entry-level psychology courses. The results obtained indicate that from the perspectives of both the student and the instructor, the integration of this technology was positively perceived to enhance the learning process and the acquisition of these skills. It would seem these concepts are, after all, not antithetical.展开更多
