Abstract

This study aims to find out that the Problem Based Learning (PBL) learning model can improve the mathematics learning outcomes of class XI students of SMA Negeri 1 Tigabinanga on linear programming material. The subjects in this study were 34 students of class XI IPA 5 at SMA Negeri 1 Tigabinanga and the object of this study was to increase students' mathematics learning outcomes through the Problem Based Learning model. The research instruments used were tests and reflective journals. This research is a classroom action research (PTK) which lasts for two cycles. The results of data analysis were obtained from the results of students' mathematics learning which increased from cycle I to cycle II after applying the Problem Based Learning learning model. In the pre-test cycle I, the average class value was 60.35 and the classical completeness was 20.59%. The results of the post-test cycle I obtained an average value of 74.12 with a classical completeness of 47.06%. Where there is an increase of 13.77 with an N-Gain value of 0.23 which is included in the low category. And the second cycle for the pre-test obtained an average value of 66.44 with a classical completeness of 32.35%. Meanwhile, the post-test results obtained an average value of 85.26 with classical completeness of 88.24%. In cycle II, the average increase was 18.71 and the N-Gain value obtained was 0.50, which is included in the medium category and has reached an indicator of cycle success. So, based on the results of this study, the learning outcomes of class XI IPA 5 SMA Negeri 1 Tigabinanga can be increased by using the Problem Based Learning learning model.

Abstract

This study aims (1) to find out how the efforts are being made to improve the mathematical problem solving abilities of class VIII-3 students of SMP Negeri 5 Pematang Siantar through the jigsaw type cooperative learning model, (2) to find out how to increase the mathematical problem solving abilities of students in class VIII- 3 SMP Negeri 5 Pematang Siantar after the implementation of the jigsaw cooperative learning model. The subjects in this study were 30 students in class VIII-3 at SMP Negeri 5 Pematang Siantar. The object of this research is the application of the jigsaw cooperative model to improve the mathematical problem solving skills of class VIII-3 students of SMP Negeri 5 Pematang Siantar for the 2022/2023 academic year. This type of research is class action research (classroom action research). This research consists of two cycles. Before giving action, an initial ability test is first given to determine students' initial abilities. From the results obtained it can be concluded that the class has met the indicators of research success. The results of this study indicate that the jigsaw type cooperative learning model can improve the mathematical problem solving skills of students in class VIII-3 SMP Negeri 5 Pematang Siantar in the 2022/2023 academic year.
