Abstract

Mathematical problem-solving ability is a core competency in mathematics learning, yet many students still struggle to solve problems that differ from the examples given by the teacher because instruction remains dominated by conventional methods. This study is motivated by the low mathematical problem-solving ability of Grade VIII.3 students at SMP Negeri 12 Padang. The REACT learning model is considered a suitable alternative because its five stages connect mathematical concepts to real-life contexts and support each problem-solving indicator. The study aims to determine whether the mathematical problem-solving ability of Grade VIII.3 students at SMP Negeri 12 Padang after applying the REACT learning model is better than before its application, and whether there is an increase in students' mathematical problem-solving ability through the implementation of the REACT learning model. This is a pre-experimental research using a one-group pretest-posttest design. The sampling technique used was purposive sampling, with Grade VIII.3 students as the research subjects. The instrument used consisted of essay-format pre-test and post-test questions. The data analysis techniques employed were the t-test and N-Gain to measure the improvement. The results showed that the average pre-test score was 30.92, while the average post-test score was 57.52. The hypothesis test results at a significance level of a=0.05 obtained tcount=6.496 and ttable=2.040. Because tcount > ttable, the proposed hypothesis is accepted. Thus, the students' mathematical problem-solving ability after implementing the REACT learning model is significantly better than before its implementation. The gain score results showed an average increase of 26.61, categorized as moderate, while the N-Gain results showed an average score of 0.40, also falling into the moderate category. Therefore, there is a moderate improvement in students' mathematical problem-solving ability through the application of the REACT learning model.

Abstract

Understanding mathematical concepts is a fundamental component of learning mathematics, yet many students only memorize formulas without grasping the underlying concepts. Learning models that engage students actively and help them construct knowledge independently, such as CORE, are therefore needed. This study was motivated by the still-low level of mathematical conceptual understanding among 11th-grade students in Class F2, Phase F, at Sijunjung State High School No. 8. The purpose of this study was to determine whether students’ mathematical conceptual understanding improved after the implementation of the Connecting, Organizing, Reflecting, Extending (CORE) learning model compared to before its implementation. The research design used was a pre-experimental study with a one-group pretest-posttest design. The population for this study consisted of all 11th-grade students in Phase F at Sijunjung State High School 8. The sampling technique used was purposive sampling, with the research subjects being the students in Class XI F2. The instruments used were pretest and posttest questions in the form of essay-type tests. The data analysis technique used was the t-test. Based on the data analysis, it was found that the research subjects’ data followed a normal distribution. The mean pre-test score was 13.22, and the mean post-test score was 62.33. The results of the hypothesis test yielded a calculated t-value of 20.30 and a critical t-value of 2.050. Since the calculated t-value was greater than the critical t-value, the proposed hypothesis was accepted. Thus, it can be concluded that the students’ ability to understand mathematical concepts after the implementation of the CORE learning model was better than before its implementation in Class XI F2, Phase F, at Sijunjung State High School 8.
