Abstract

This study aims to determine the influence of the Problem Based Learning (PBL) model on students' learning outcomes in the Social Studies (IPS) subject for Grade VIII at SMP Negeri 3 Pematangsiantar. The background of this research is based on the low learning outcomes of students, which are caused by the lack of active student involvement during the learning process. The PBL model was chosen because it emphasizes student involvement in solving real problems, which is expected to improve both understanding and learning outcomes. This research employs a quantitative approach with a quasi-experimental method. The research design used is the Nonequivalent Control Group Design involving two classes, namely class VIII-1 as the experimental group that applied the PBL model, and class VIII-2 as the control group that received conventional learning. Data collection techniques were carried out through pre-test and post-test. Instrument testing included validity, reliability, normality, homogeneity tests, and hypothesis testing using the Independent Samples t-Test with the assistance of SPSS version 26. The results of the study show that there is a significant difference in learning outcomes between students who were taught using the PBL model and those who were taught using conventional methods. The significance value in the t-test was 0.001 < 0.05, with the average N-Gain score of the experimental class being 44.67% and the control class being 31.24%. This indicates that the application of the PBL model has a significant effect on improving student learning outcomes.

Abstract

This study aims to determine the influence of the Jigsaw Type Cooperative Learning Model on student learning outcomes in Social Studies (IPS) for eighth-grade students at UPTD SMP Negeri 12 Pematangsiantar in the 2024/2025 academic year. The research employed a quantitative approach using a quasi-experimental method with a Pretest-Posttest Control Group Design. The sample was selected through purposive sampling: class VIII-4 as the experimental group using the Jigsaw Type Cooperative Learning Model, and class VIII-3 as the control group using the conventional (lecture) method, with 32 students in each class. The research instrument consisted of a multiple-choice test with 25 items, which had been tested for validity, reliability, difficulty level, and discriminating power. The validity test showed that all items were valid (r count > r table = 0.349), with the highest validity coefficient being 0.8019 and the lowest 0.3665. The instrument's reliability was 0.807 > 0.396, indicating that the test was reliable. The normality test indicated that both classes had normally distributed data (X² count < X² table), and the homogeneity test indicated that both groups were homogeneous (F count = 1.025 < F table = 1.804). The results showed that the experimental class had an average score of 80 with a standard deviation of 10.36, while the control class had an average score of 74.25 with a standard deviation of 10.10. The t-test revealed t count = 2.21 > t table = 1.67, indicating a significant difference in learning outcomes between the two classes. Therefore, it can be concluded that the Jigsaw Type Cooperative Learning Model has a significant influence on student learning outcomes in Social Studies and is more effective than the conventional method.

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.
