Abstract

This research aims to determine the effect of the Reward-based Problem Based Learning learning model on the mathematical learning outcomes of class IV at SD Negeri 060919 Medan Sunggal for the 2024/2025 academic year. The procedures and techniques used in research are called research methodology. The aim of this quantitative research strategy is to identify factors that contribute to the success or failure of various learning approaches in improving academic achievement in mathematics classes with fractions as the main material in class IV. This can be seen from the average student pretest score of 43.33 and the average score of -student posttest average 74.33. Based on the results of the hypothesis test (t-test) with a value of ≥, namely 5,806 2.048 at a significance level of 0.000 0.05. These data can show that Ha is accepted, namely that there is an influence between the Problem Based Learning learning model based on giving rewards (X) on student learning outcomes (Y). At the end of the lesson, the researcher provided treatment using a Problem Based Learning learning model based on giving rewards when teaching, then the researcher tested the students again by giving a posttest of 10 questions to see the value of the treatment given. By using the Problem Based Learning learning model based on giving rewards, students' posttest learning outcomes increased with an average score of 74.33 and there were 29 students who completed and 1 student who did not complete. So the final step that the researcher took was to give a 25-item Problem Based Learning model questionnaire to students.

Abstract

This research aims to determine the effect of the Google Site-based jigsaw type cooperative learning model on the mathematics learning outcomes of fourth grade elementary school students Negeri 16 markets 1 nainggolan 2023/2024 academic year. The research method used is an experimental method with a quantitative research type. To obtain the data required a test instrument of 30 questions. The total research sample was 26 students based on Random Sampling techniques. To determine students' initial abilities, the research conducted a Pre Test with an average score of 57.76 which was included in the poor category. The results of the Posttest have improved from the Pretest results given previously with the students' average score reaching 86.26 in the good category and the average score from the questionnaire being 83.42. It can be said that students' speaking skills have improved as evidenced by the results of the correlation coefficient test calculation, which obtained r_count ≥r_tabel with results of 0.722 ≥ 0.388. Next, hypothesis testing compares the t_count ≥t_table value. Obtained t_count value ≥t_table (5.115 ≥ 2.048) then H_a is accepted and H_o is rejected. Through the t-test, it can be concluded that there is a significant positive influence between the Role Playing method (X) on students' speaking skills (Y).
