Oral interaction in cooperative learning groups: speaking, listening, and the nature of statements made by high-, medium-, and low-achieving students.

Oral interaction within cooperative learning groups was observed for high-, medium-, and low-achieving students. Initially, cooperative and individualistic learning situations were compared on achievement and attitudes. Forty-eight 4th-grade American students were assigned to learning situations on a stratified random basis controlling for ability and sex. They participated in the study for 55 min a day for 15 instructional days. Two observation schemes were used. The results for the cooperative situation were factor analyzed to determine the basic dimensions of oral interaction within cooperative learning groups. Five orthogonal factors were identified: Exchanging Task-Related Information, Elaborating on the Information, Encouraging Each Other to Learn, Disagreeing With Each Other's Conclusions, and Making Nontask Comments and Sharing Personal Feelings. The oral participation of students from different achievement levels was differentially related to achievement. Vocalizing was found to be more strongly related to achievement than was listening to other group members vocalize. Medium and low achievers especially benefited from cooperative learning experiences.
