Some advocates of cooperative learning suggest that the most effective cooperative groups are those that include a wide range of student ability levels. How can we best summarize research findings regarding the effectiveness of different kinds of groups?
a. These advocates are correct; heterogeneous grouping maximizes student achievement.
b. Low-ability students do better when placed with high-ability students, but middle-ability students work best with students very similar to themselves in ability.
c. High-ability students rarely, if ever, benefit from working with low-ability students.
d. Research results are inconclusive with regard to the optimal range of ability levels within a particular group.
