Barkley (2010) suggests that having members of a group read and individually sign a contract regarding their participation and behavior in the group will improve interpersonal accountability. EDU222 students are required to collaborate and submit a group case study. At the conclusion of the project, they rate each of their group members on a variety of contributing characteristics (see "Member Rating" attachment). Noting that average member ratings averaged in the 80% range, the author adopted Barkley's rubric to meet his needs and implemented the rubric in his Spring 2012 classes (see "Group Contract" attachment). Students in each group round-robin read the contract, and initialed each agreement. After the project, member ratings improved to an average of 88%. Moreover, student feedback about the contract was extremely positive. This contract is now in use in all of the author's classes with collaborative projects.
