Abstract

This study aims to determine the effect of the snowball throwing cooperative learning model on student learning outcomes in social studies class VII at Teladan Private Middle School Pematang Siantar T.A 2022/2023. The study used a quasi-experimental method (quasi-experimental) with the Nonequivalent Control Group Design. This design consists of two stages, namely pretest and posttest. The sample in the study in class VII was 22 students and VII-2 was 22 students. The research instrument used was the learning achievement test. From the results of the analysis carried out in the experimental class with an average pretest score of 49.95 and a posttest of 70.68. While in the control class with an average pretest score of 50.23 and a posttest average score of 52.73. The results of testing the hypothesis using an independent sample t-test obtained tcount 4.941 > ttable 1.684 and a significance of 0.000 <0.005 so that it can be concluded that student learning outcomes are taught using the snowball throwing cooperative learning model which is influential and well used in learning.

Abstract

This study aims to obtain knowledge about the influence of parental income and social style on financial behavior of students of the economic education study program, HKBP Nommensen Pematang Siantar University This type of research is a quantitative research with a quantitative descriptive data analysis approach with the testing medium used is SPSS 22. The total population in this study was 267 people, and the sample used was 160 people The sample collection technique used was simple random sampling. The data collection technique used is a questionnaire (questionnaire). The hypothesis data collection technique uses multiple regression analysis and determination coefficient (R2). obtained a = 17.510, b1 = 0.494, b2 = 0.272 and e = 3.371. Contribution can be determined by squaring the simple influence "R" which can be formulated as follows: 100. r2 % Contribution between parents' income to students' financial behaviour Data r = 0.593, then r2 = 0.3516. Thus, the influence of parents' income on students' financial behavior is expressed in the form of percentages as follows: 100. r2 % = 35.16%. The contribution between social styles to students' financial behavior was obtained with data r = 0.509, then r2 = 0.2591. Thus, the influence of social style on students' financial behavior is expressed in the form of percentages as follows: 100. r2 % = 25.91%. The contribution between parents' income and social style to students' financial behavior was obtained data r = 0.593, then r2 = 0.3516. Thus, the influence of parents' income and social style on students' financial behavior is expressed in the form of percentages as follows: 100. r2 % = 35.16%.

Abstract

This study aims to determine the effect of the Cooperative Integrated Reading and Composition (CIRC) learning model on student learning outcomes in Social Sciences (IPS) subjects in class VIII of Tamansiswa Private Junior High School Pematangsiantar in the 2025/2026 Academic Year. This type of research is a quantitative experiment with a Nonequivalent Control Group Design. The research sample consisted of two classes, namely the experimental class using the CIRC learning model and the control class using the lecture method. The data collection technique used learning outcome tests in the form of pretests and posttests. Data analysis was carried out through normality tests, homogeneity tests, and t-tests using the SPSS 26 application. The results showed that there was a significant increase in student learning outcomes after the implementation of the CIRC learning model. The average pretest score of the experimental class was 48.41, increasing to 72.76 in the posttest, while the control class increased from 44.55 to 68.00. Based on the results of the t-test, a significance value of 0.000 <0.05 was obtained, which means that Ha was accepted and H0 was rejected. Thus, it can be concluded that the application of the Cooperative Integrated Reading and Composition (CIRC) learning model has a significant effect on student learning outcomes in social studies subjects.
