We will present three similar studies that examine online peer evaluation of student-generated explanations for missed exam problems in introductory physics. In the first study, students created video solutions using YouTube and in the second two studies, they created written solutions using Google documents. All peer evaluations were performed using a tournament module as part of the interactive online coaching system called E2Coach[4] at the University of Michigan. With the theme of LAK 2014 being "intersection of learning analytics research, theory and practice", we think this poster will provide an accessible example that combines a classroom experiment with rigorous analysis to understand outcomes. |
