Effects of the Jigsaw and Teams Game Tournament (TGT) Cooperative Learning on the Learning Motivation and Mathematical Skills of Junior High School Students

This study aims to: 1) describe the effectiveness of the jigsaw and TGT cooperative learning in the learning motivation and mathematical skills of junior high school (JHS) students, and 2) investigate the significant difference in the learning motivation and mathematical skills between the JHS students learning through the jigsaw cooperative learning and those learning through the TGT cooperative learning. This study was a quasi-experimental study using the non-equivalent pretest and posttest group design. This study involved two experimental classes. The research population comprised Year VII students of SMP Pembangunan Piyungan and the research sample consisted of two classes selected from all Year VII groups, with Year VII.A receiving a treatment of the jigsaw cooperative learning and Year VII.B receiving a treatment of the TGT cooperative learning. The instruments consisted of a test, i.e. a mathematical skill test, and a non-test, i.e. a questionnaire of mathematics learning motivation. To investigate the effectiveness of the jigsaw and TGT cooperative learning in the learning motivation and mathematical skills of JHS students, the data were analyzed using the one sample test. To investigate the significant difference in the learning motivation and mathematical skills between the students learning through the jigsaw cooperative learning and those learning through the TGT cooperative learning, the data were analyzed using the T2 Hotelling. To compare the effectiveness of the jigsaw and TGT cooperative learning in the learning motivation and mathematical skills of the students, the data were analyzed using the t-test. The normality was tested using the univariate approach, namely the Kolmogorov Smirnov, the homogeneity using the Box' M test, and the equivalence of the variance-covariance matrix using the Levene's test. The results of the study show that: 1) the jigsaw cooperative learning is effective for the JHS students’ mathematical skills and mathematics learning motivation; 2) the TGT cooperative learning is effective for the JHS students’ mathematical skills and mathematics learning motivation; 3) there is a difference in the effectiveness of the jigsaw and TGT cooperative learning in the JHS students’ mathematical skills and mathematics learning motivation; 4) the jigsaw cooperative learning method is more effective than the TGT cooperative learning method for the JHS students’ mathematics learning motivation; and 5) the jigsaw cooperative learning method is more effective than the TGT cooperative learning method for the JHS students’ mathematical skills.
