The purpose of this study was to determine whether the application of the example non example learning model can significantly improve the mathematics learning outcomes of third grade students of Kertosari State Elementary School. This type of research uses experimental methods, with a one-group pretest-posttest design. The place and time of the research was conducted at SD Negeri Kertosari, Musi Rawas Regency with the research time in the even semester. The population of this study amounted to 13 third grade students of SD Negeri S Kertosari, the research sample used saturated sampling technique. Data collection techniques Pre-Test and Post-Test with multiple choice questions as many as 15 items. From the results of data analysis using the Z-test with a significant level of ɑ = 0.05, it was found that Zcount ˃ Ztabel (4.71 ˃ 1.64), so it can be concluded that there are learning outcomes in mathematics of third grade students of Kertosari State Elementary School by applying the example non example learning model.

This research is classroom action research (PTK) carried out at SMAS GUPPI Samata, Gowa Regency which aims to improve mathematics learning outcomes by using the Example Non Example type cooperative learning model. The subjects of this research were class XII students with a total of 26 students. Data collection was carried out using learning outcomes tests. The collected data was analyzed using quantitative and qualitative analysis. The research results showed that the average score of student learning outcomes in cycle I reached an average of 82.38 and in cycle II reached an average of 86.15. The standard deviation in cycle I was 5.721 and in cycle II was 4.315. Based on the category of completeness of learning outcomes used, the score obtained for students' mathematics learning outcomes which were categorized as complete in cycle I was 73.07% and in cycle II it increased to 100%. From these results it can be concluded that there has been an increase in mathematics learning outcomes by using the Example Non Example type cooperative learning model.
