Abstract

Low student mathematics learning outcomes remain a problem at MTsN 3 Mataram. End-of-Semester Summative Data shows that most eighth-grade students have not yet achieved the Minimum Achievement Criteria. In addition, the learning process is still dominated by lecture methods so that students tend to be passive and less motivated in participating in learning. This study aims to determine the effect of the Teams Games Tournament (TGT) cooperative learning model based on Clash of Champions on the mathematics learning outcomes of eighth-grade students at MTsN 3 Mataram in the 2025/2026 academic year. This study uses a quantitative approach with a quasi-experimental method and a posttest-only control group design. The research sample consisted of students of grades VIII-3 as the experimental class and VIII-2 as the control class selected using a purposive sampling technique. Learning outcome data were obtained through a posttest and analyzed using normality tests, homogeneity tests, t-tests, and effect size. The results showed that the average posttest score of the experimental class was 80.83, higher than the control class at 66.50. The t-test results show that is greater than 1,99, so there is a significant difference between the two classes. The effect size value of 0.93 indicates a high influence category. Thus, the cooperative learning model of the Teams Games Tournament (TGT) type based on Clash of Champions has a positive effect on students' mathematics learning outcomes.

Abstract

This study aims to determine the effect of Canva-based interactive learning media on students’ mathematics learning outcomes in Grade VIII at MTs Negeri 3 Mataram during the 2026/2027 academic year. This research employed a quantitative approach using a Posttest-Only Nonequivalent Control Group Design. The research sample consisted of 71 students, including 35 students in the experimental class who received instruction using Canva-based interactive learning media and 36 students in the control class who were taught using conventional textbook-based learning media. Data were collected through a mathematics learning outcomes test on the topic of exponents. The collected data were analyzed using normality tests, homogeneity tests, an Independent Samples t-test, and an effect size analysis. The results showed that the mean posttest score of students’ mathematics learning outcomes in the experimental class was 78.43, while the control class obtained a mean score of 60.75. The homogeneity test indicated that the data had homogeneous variances, with a significance value of 0.188 > 0.05. Furthermore, the hypothesis testing using the Independent Samples t-test revealed that the calculated t-value of 4.460 was higher than the t-table value of 1.995 at a significance level of 0.05, indicating that the null hypothesis () was rejected and the alternative hypothesis () was accepted. In addition, the calculation of the effect size using Cohen’s d resulted in a value of 1.059, which was categorized as a high effect. Based on these findings, it can be concluded that Canva-based interactive learning media has a positive and significant effect on students’ mathematics learning outcomes in Grade VIII at MTs Negeri 3 Mataram during the 2026/2027 academic year.
