Abstract

The problem in this study is the low economic learning outcomes of students in the learning process. This study aims to determine the improvement of economic learning outcomes on the subject of monetary economic policy and fiscal economic policy of class Xl SMA Negeri 5 Pematangsiantar Learning Year 2023-2024 by applying a jigsaw type cooperative learning approach.This type of research is Classroom Action with quantitative methods Pretest and Post-test. The population of this study was class XI SMA Negeri 5 Pematangsiantar which amounted to 175 people. Based on purposive sampling technique, the researcher took the research sample is 2 classes, namely class XI IPS 1 (experimental class) and class XI IPS 2 (control class) which amounted to 71 people. Data collection techniques in the study using pretest without applying the jigsaw type cooperative learning model and posttest by applying the jigsaw type cooperative learning model to the experimental class. The results of the average value of the pretest namely class XI IPS 1 66.29 and XI IPS 2 44.72. Then the results of the average value of the post-test is XI IPS 1 79.14 and XI IPS 2 70.27. Based on the results of data analysis and hypotheses tested, that the jigsaw type cooperative learning model affects student learning outcomes.Based on the statistical hypothesis test with paired samples test, the significance value is 0.000 <0.05 in the sense that the calculated statistical results (t output number) < table statistics (t table) it is concluded that H0 is rejected and H1 is accepted. Thus the Jigsaw Type Cooperative learning model affects the learning outcomes of students in class Xl SMA Negeri 5 Pematangsiantar.

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.

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.
