Abstract

This study aims to determine the profile of skills and improvement of critical thinking of students before and after implementing differentiated learning through the Problem Based Learning model on the material of heat and its transfer. The method used is a Pre-Experimental Design with a One Group Pretest-Posttest Design. The research sample consists of one class with 31 students. The research data were obtained by providing a critical thinking skills test in the form of pretest and posttest questions consisting of 5 essay questions. The results show that the average score for the pretest is 47.90% (medium category) and the posttest is 69.03% (high category). Based on calculations using paired sample tests, a sig (2-tailed) value of 0.00 < 0.05 indicates a significant improvement in posttest scores after treatment with differentiated learning through the Problem Based Learning model. Therefore, it can be concluded that differentiated learning with the Problem Based Learning model can enhance students' critical thinking skills on the topic of heat and its transfer.

Abstract

This study aims to test the effect of the application of the Problem Based Learning (PBL) learning model based on differentiated learning on the improvement of students' critical thinking skills in work and energy materials at SMP Negeri 2 Selakau Timur. This study uses a quantitative method with a pre-experimental experiment design, namely by using one pretest-posttest group. The results of the study show that the application of the PBL model based on differentiated learning is able to significantly improve students' critical thinking skills. The average score of the pretest students was 17.25, while after the implementation of PBL learning, the posttest score increased to 84.83. This increase is evident with an N-gain value of 0.81, which indicates a high category of improvement. In addition, the implementation of differentiated learning with the PBL model reached an average of 90-92%, indicating that the learning went well and as expected. Based on the results of this study, it can be concluded that differentiated learning with the PBL model is effective in improving students' critical thinking skills, especially in work and energy materials.
