The Effect of Problem-Based Learning Model on Mathematics Problem-Solving Ability in Class XI SMAS PPM Rahmatul Asri

Abstract

This study aims to determine whether there is an effect of the Problem Based Learning Model on students' problem-solving abilities. This type of research is a quasi-experimental involving two groups that are given different treatments. The population of this study was students of class XI SMAS PPM Rahmatul Asri, and two classes were selected by cluster random sampling as the research sample, namely class XI Science 1 and XI Science 2. Class XI Science 1 is an experimental class taught using the Problem Based Learning Model, while XI Science 2 is a control class taught using conventional learning. The research instrument was used in the form of a problem-solving ability test in the form of a test in the form of a description. The data collected using the instrument was analyzed using descriptive and inferential statistical techniques. The results of the descriptive analysis showed that: (1) the problem-solving ability of students after being taught using the Problem Based Learning Model was in the very good category, namely84.56 from the ideal score of 100, (2) the problem-solving ability of students after being taught using conventional learning is in a good category, namely 75.39from the ideal score of 100. The results of inferential statistical analysis show that: (1) with the Wilcoxon test, it can be said that there is a significant difference between the problem-solving ability score parameters of students in class XI science who are taught using the Problem Based Learning Model and the parameter scores of problem-solving abilities of students in class XI science who are taught using conventional learning. From the results of this study, it can be concluded that the problem-Based Learning Model influences students' problem-solving abilities.
