In jigsaw groups, students are interdependent. Social acceptance of others increase because students need to help each other and learn from each other. Students' academic achievement is raised when all students work together towards a common goal. High achieving students learn tolerance and understanding of individual differences. Lower achieving students develop a greater understanding of subject matter.
Students are highly motivated to work within a group.
Also, teamwork helps students learn interpersonal skills, which is especially beneficial to second language learners. Jigsaw groups can foster appreciation of diversity.
