Abstract

This qualitative descriptive research aims to describe students' mathematical problem solving abilities based on Polya indicators in solving social arithmetic problems in terms of self-efficacy. The research subjects were 4 students in class VII of SMP Negeri 4 Gunung Sari for the 2022/2023 academic year, consisting of 2 students in the high category and 2 students in the low category. Data collection techniques using questionnaires, tests and interviews. Data analysis techniques include data reduction, data presentation, and drawing conclusions. The results of this research were obtained from (i) students with level self-efficacy high have high mathematical problem solving abilities can go through all stages of problem solving abilities, namely understanding the problem, preparing a plan, implementing the plan, and checking again. (ii) students by level self-efficacy Low students have low mathematical problem solving abilities which can also be seen from the results of students' work through only two stages, namely the stage of understanding the problem and implementing the plan. With suggestions for students who are at each category level self-efficacy and the level of mathematical problem solving abilities, it is hoped that they can further maximize their abilities

Abstract

This research aimed to determine the effect of the Realistic Mathematics Education (RME) learning model on students critical thinking ability for systems of linear equations with two variabels material in class VIII at SMP Negeri 3 Jerowaru for the academic year 2023/2024. Research with a quantitative approach that uses a quasi-experimental design, the experimental class learning using the RME learning model while the control class using direct learning. The population in this study was 3 class VIII students. The samples were taken using a simple random sampling technique, resulting in class VIII A as the experimental class and VIII B as the control class. Data collection was carried out using critical thinking ability test questions (posttest). From the research results, it was found that there were differences between the experimental class and the control class. Judging from the average score of the experimental class 69.08 and the control class 58.40, this shows that the critical thinking ability of the class whose learning uses RME is better than the class whose learning uses direct learning. The effect size test results obtained were 0.69, which is in the medium category. So it can be concluded that there is an effect of the RME learning model on students' critical thinking skills in SPLDV material in class VIII of SMP Negeri 3 Jerowaru in the medium category. Keywords: Realistic Mathematics Education (RME) Learning Model, Critical Thingking Ability, Systems of Linear Equations with Two Varabels
