Abstract

This development research aimed to create physics learning tools based on problem based learning model using PhET simulation that are feasible, practical and effective to improve students' conceptual understanding. This research is a Research and Development (R&D) using 4D model developed by Thiagarajan (1974) which is consisted of define, design, develop, and disseminate. The learning tools being developed were syllabus, lesson plan, material, students' worksheet, and instrument of concept comprehension. The results of product validity developed as a whole from expert validators and practitioners have a very valid and reliable category with an average percentage above 75%, so it can be said to be feasible. The results of the practicality of the product developed of a teacher and student response questionnaire have a very practical category. The results of the N-Gain test for understanding the physics concepts of students obtained a moderate improvement category and were included in the quite effective category. So it can be conluded that the resulting development product is feasible, very practical and effective enough to improve students’ understanding of physics concepts.

Abstract

This study aims to determine whether there is an effect of the problem-based learning model on the problem-solving and critical thinking skills of class XI students of SMAN 1 Praya Tengah. experimental and control classes, where class XI IPA 2 is the experimental class and class XI is IPA 3 is the control class. The experimental class was given treatment in the form of applying a problem-based learning model and the control class was given treatment in the form of applying a direct instruction learning model. Data on problem-solving abilities and critical thinking were measured using a comparison of the initial test with the final test in the form of 8 essay questions to measure problem solving abilities and 4 essay questions. to measure students' critical thinking skills. The research hypotheses were tested with the manova test with a significant level of 5%. Based on the results of the analysis that has been carried out, the results of the hypothesis that Ho is rejected and H is accepted. So it can be concluded that there is an effect of problem-based learning model in improving problem solving and critical thinking
