Word From the Web

This is the first of a regular column that will share ideas from the Web about new trends, research, connections, etc. A paper on peer feedback, along with other good stuff on CL, can be found on Richard Felder's website: www2.ncsu/edu/unity/lockers/users/f/felder/public/RMF.html

The reference is: Kaufman, D. B, Felder, R. M., & Fuller, H. (1999, June). Peer ratings in cooperative teams. Paper presented at the annual meeting of the American Society for Engineering Education, Charlotte, North Carolina.

A peer rating system developed at the Royal Melbourne Institute of Technology was modified and used in two sophomore-level chemical engineering courses. The students completed their homework in instructor-formed teams in each course, and an average homework grade was computed for each team. At the end of each course the students confidentially rated how well they and each of their teammates fulfilled their team responsibilities, taking the ratings from a prescribed list of nine terms ranging from "excellent" to "no show." The instructor assigned numerical values to each rating and computed a weighting factor for each student as the student's individual average rating divided by the team average. The student's final homework grade was the product of the weighting factor and the team project grade. Correlations were computed between peer ratings and test grades, peer ratings and self-ratings, ratings given to teammates of the same sex and of the opposite sex, and ratings given to teammates of the same ethnic background and of different ethnic backgrounds.

Peer ratings correlated significantly with test grades, indicating that the more responsible students tended to be those who did best academically and/or that the academically stronger students were perceived as contributing most to the team effort. Self-ratings were remarkably consistent with peer ratings. Students rarely rated themselves higher than the rest of their teammates rated them; in fact, more (although still relatively few) gave themselves ratings lower than any they received from teammates. The incidence of identical ratings for all members of a team was also relatively low, on the order of 5-10% of all teams.

No evidence of gender bias appeared in the data. Non-minority students gave lower ratings to minority students than to other non-minority students; racial prejudice could account in part for this result, but other explanations are equally likely or more so. Roughly 7% of the students were revealed as possible hitchhikers (as evidenced by their receiving less than satisfactory peer ratings from their teammates), but complaints about the system were almost non-existent. Most of the concerns frequently raised about peer ratings in cooperative learning were thus not borne out by the results of this study. Much additional research will be needed before the concerns can be definitively set aside.

One appealing contribution to this listserve is Ted Panitz' cooperative learning E-book. The table of contents includes some intriguing items, such as "Student testimonials" and "Why more teachers do not use CL."
