Nahit Menteşe Vocational and Technical High School implemented cooperative learning techniques in English, math, history, and literature lessons with 100 students in focused groups that had high absentee rates. Questionnaires given to students and teachers found that cooperative learning increased academic performance, self-esteem, motivation, and social skills. While time-intensive for teachers, it engaged inactive students and developed critical thinking. The school plans to continue training teachers in cooperative learning and applying self-efficacy surveys to identify at-risk students.
