Problem-based group activities for sensation and perception

I have incorporated 14 group activities into my Sensation & Perception course with the intent to provide a problem-based learning approach to the course. For each activity, students decide for themselves what information is applicable to a problem and formulate their own solutions.

Each activity requires approximately 30-50 min, making it suitable for most class periods. I have found that this works well for a class size of about 30 students. For larger classes, an increased number of groups would require either elimination of the group reports to the class or increased time to hear from each group. The only materials required are an instruction sheet for each activity and the self-assessment evaluation sheet, both of which are included in this document.
