Abstract

This research was motivated by the low learning outcomes of students in social studies, where students tended to be passive and the learning process lacked variation. The objective of this study was to determine the effect of the Discovery Learning teaching model on students' learning outcomes. This study is a quantitative research with a quasi-experimental method. The research sample consisted of two classes: class VIII-B as the experimental group, which was taught using the Discovery Learning model, and class VIII-C as the control group, which was taught using conventional methods. Data were collected through test instruments in the form of pre-test and post-test questions for both classes. The results showed a significant difference in student learning outcomes between the experimental and control groups. Based on the hypothesis test (t-test), the t-count value of 5.12 was greater than the t-table value of 1.67 (at a 0.05 significance level). Thus, the null hypothesis (H0) was rejected and the alternative hypothesis (Ha) was accepted. This proves that there is a significant effect of implementing the Discovery Learning teaching model on students' learning outcomes.

Abstract

This study aims to determine the Effect of the Numbered Heads Together Cooperative Learning Model on Student Learning Scores in the Economics Subject of Class XI of Tamansiswa Private High School Pematangsiantar in the 2025/2026 Academic Year. The type of research used in this study is quantitative with a quasi-experimental design through a Nonequivalent Control Group Design. The study population consisted of all students of class XI Merdeka of Tamansiswa Private High School Pematangsiantar with a total of 102 students. The sample used in this study consisted of 2 classes, namely class XI Merdeka 7 as the control class and class XI Merdeka 8 as the experimental class with a total of 69 students. Based on the results of the study, it shows that the learning scores of students who do not use conventional methods obtain an average score of 79.892. While the learning scores of students who use the Numbered Heads Together cooperative model obtain an average score of 93.125. The t-test results also support this research, where the t-count value is 6.682 and the t-table value is 1.996, where the t-count > t-table with a significance level of 0.05. Thus, Ho is rejected and Ha is accepted. This proves that there is a significant influence of the Numbered Heads Together cooperative learning model on student learning scores in the Economics subject of class XI at Tamansiswa Private High School, Pematangsiantar.
