A Flip of the Coin—A Roll of the Die: An Answer to the Free-Rider Problem in Economic Instruction

Abstract

This article reviews some of the literature on collaborative learning and identifies a free-rider problem inherent in assigning grades to students participating in cooperative learning activities. The author's solution: one member or each group is identified randomly to take the exam or to make the presentation, and the grade earned by that student is assigned to all members of the group.
