Mathematical Problem Solving Ability: Comparison between Application of Discovery Learning Model and Problem Based Learning in Class VIII Students of SMPN 2 Majene

Abstract

The research aims to determine whether there is a difference in mathematical problem-solving ability between the application of the discovery learning model and problem-based learning models in grade 8 at SMPN 2 Majene. This type of research is quasi-experimental with a nonequivalent control group design. The population studied were all class VIII students at SMPN 2 Majene, Majene Regency, which was divided into 6 classes, and then the sample was selected using simple random sampling. In analyzing the data, descriptive and inferential statistical analyses were used. The results showed that the average mathematical problem-solving ability with the application of the discovery learning model was 63.97, with a standard deviation of 12.783. On the other side, the average mathematical problem-solving scores of students taught using the problem-based learning model is 72.31, with a standard deviation of 16.175. The results of the inferential analysis show that there are differences in mathematical problem-solving abilities between those who apply discovery learning and problem-based learning with the results of the calculation of the sig value. 0.014 < 0.05 which means H0 is rejected. Thus, it can be seen that the mathematical problem-solving ability of students taught using applying the problem-based learning model is higher than the application of the discovery learning model.
