Model effect Jigsaw cooperative learning on mathematics learning outcomes materials for building space in elementary school

This study aims to analyze the effect of the Jigsaw model on the mathematics learning outcomes of class VI students in the material of geometry in the Wijayakusuma Cluster, Karangtengah District. The research design used experimental research. The research population was all sixth-grade elementary school students in the Wijayakusuma Cluster. Sampling technique using random sampling. The research instruments used were tests, observations, interviews, and documentation. The data were collected through observation, interviews, and documentation, with data descriptions, normality and homogeneity tests, hypothesis testing. Learning outcomes using the Jigsaw model in Mathematics learning at the posttest were able to achieve a class average of 82.59 and learning completeness 92.59%, while the average learning outcomes of the control class were 75.00 and learning completeness was 77%. The value of t sat or t count = 2.3966 while the value of one-tail 0.190 or t table is 1.6772. So the conclusion that Ho affects the treatment in the experimental class is accepted because t count > t table is 2.3966 > 1.6772. It can be seen that there is an effect of the Jigsaw model on the learning outcomes of Class VI students of SDN Dukun 1, Karangtengah Subdistrict, Demak Regency.
