The present investigation examined the effectiveness of cooperative learning techniques, as compared to regular classroom learning, in increasing positive interethnic attitudes and increasing academic performance. Eighty-eight students from six Introductory Psychology labs at California State University, Fresno served as subjects. The six labs were assigned to one of three learning conditions: Jigsaw, Discussion, and Control. Subjects were administered a pretest which included the Modern Racism Scale and the Social Attitudes Scale. Experimental conditions were implemented over the course of 9 weeks with subjects blind as to their participation in the investigation. Weekly quizzes which measured subjects' knowledge of lesson material learned within the experimental conditions were administered. At the conclusion of 9 weeks, subjects received a posttest consisting of the Modern Racism Scale and Social Attitudes Scale. The major finding of this study was that the jigsaw did not significantly reduce prejudicial attitudes or increase academic achievement of college-age students.
