Abstract

The purpose of this study was to determine the effect of the use of the Situation Based Learning (SBL) learning model on the mathematical problem-solving ability of eighth grade students at SMP Negeri 2 Bandar Trade. The design of this study used a pretest-posttest Nonequivalent control group design. The population in this study were all class VIII students of SMP Negeri 2 Bandar Trade T.A 2022/2023, and the samples in this study were all students of class VIII-1 and class VIII-5 students of SMP Negeri 2 Bandar Trade T.A 2022/2023 totaling 60 students. The instruments used in this study are validity, reliability, level of difficulty of test items and distinguishing power of test items. The data obtained were then analyzed using data analysis techniques, the average value of the Situation Based Learning (SBL) learning model was 82.13 and the average mathematical problem-solving ability was 56.03. The results of hypothesis testing after obtained tcount = 4.97 and ttable = 1.671. It means that tcount is greater than ttable which indicates  is rejected. Based on the description, it is concluded that the use of Situation Based Learning (SBL) learning model has an influence on students' mathematical problem-solving abilities in SPLDV learning in class VIII of SMP Negeri 2 Bandar Trade

Abstract

The purpose of this study was to determine the effect of the Problem-Solving learning model on the Mathematical Problem-Solving Ability of Class XI Students of Private High School Nommensen Pematangsiantar Campus. The design of this study used a pretest-posttest control group design. The population and sample in this study were all students of class XI Private High School Nommensen Pematangsiantar T.A 2022/2023 Campus, totaling 62 students. The instruments used in this study are validity, reliability, level of difficulty of test items and distinguishing power of test items. The data obtained were then analyzed using data analysis techniques, the average value of the results of the Problem-Solving learning model on students' mathematical problem abilities was 63.39. The results of hypothesis testing after obtained zcount = 2.530 and ztable = 1.960 This means that tcount is greater than ttable which indicates the hypothesis H0 is rejected. Based on the description, it is concluded that the use of the Problem-Solving learning model has an influence on students' mathematical problem-solving abilities in learning the Composition Functions of the Private High School, Pematangsiantar Campus
