The aim of this research is to find out how the jigsaw type cooperative learning model influences the mathematics learning outcomes of class VIII students at SMP Negeri 1 Jorlang Hataran. The type of research used is Pre-Experimental Design research. Research subjects in class VIII-3 with a total of 30 students. In this research the author used a quantitative approach. The design used in this research is One-shot case study. Based on the results of data analysis and discussion, it can be concluded that there is a significant influence of the use of the jigsaw type cooperative learning model on the learning outcomes of class VIII students at SMP Negeri 1 Jorlang Hataran for the 2023/2024 academic year. This positive influence is shown through the regression equation Y= 16.816 + 0.089X where the b value is 0.089. This influence is through the t-test, namely tcount > ttable (3.608 > 2.048) or (sig.) < 0.05 (0.000 < 0.05), then H0 is rejected and H1 is accepted, which means there is a positive and significant influence from the cooperative learning model. jigsaw type on student learning outcomes in relation and function material. The contribution of variance of variable X (jigsaw type cooperative learning model) to variable Y (student learning outcomes) is 32%.
