The Impact of the Creative Problem-Solving (CPS) Learning Model on the Mathematical Reasoning Skills of 8th-grade Junior High School Students Studying Systems of Linear Equations with Two Variables

Abstract

The goal of this research is to examine the effect of the Creative Problem Solving (CPS) Learning Model on Students’ Mathematical Reasoning Abilities in the Topic of Systems of Linear equations with Two Variables for 8th-grade students in a Public Junior High School I Jabung of Malang. This study used an Experimental Design. The research subjects consist of 60 students from two groups. The sampling technique used is Random Cluster Sampling. The research instrument used is a test. The data analysis techniques include descriptive statistics, inferential statistics, and SPSS. The results of this study indicate a significant effect of the creative problem-solving Learning model on students’ mathematical reasoning abilities. This is evident from the average score in the experimental group, which is 72.600, and the average score in the control group, which is 2.200. Based on the results of the inferential statistical analysis, the post-test value obtained is t-value = 0.694, which is greater than the t-table value of 0.58. Therefore, the null hypothesis (H0) is injected, and the alternative hypothesis (H1) is accepted. This means that the Creative Problem-Solving learning model significantly affects students’ mathematical reasoning.
