Abstract

This research is based on the preliminary study conducted at SMPN 16 Padang which found that students' learning outcomes in science teaching are still considered suboptimal. This is indicated by several students' scores that have not yet met the Learning Outcome Completion Criteria of 80. This research aims to determine the effect of Problem-Based Learning (PBL) model assisted by PhET simulations on the learning outcomes of eighth-grade students at SMPN 16 Padang. The type of research is a quasi-experiment with a non-equivalent control group design. The population in this study is all the eighth-grade students of SMPN 16 Padang. Sample collection was conducted using purposive sampling techniques. Thus, the research samples were obtained from students in class VIII 2 and VIII 4. The research samples consisted of experimental class applying the Problem-Based Learning model assisted by PhET simulations and control class using the conventional learning model. Data collection was conducted through tests administered before (pretest) and after the treatment (posttest) on the experimental and control classes in the form of multiple-choice questions. The obtained data were analyzed using inferential statistical analysis, and the results of the two-sample t-test for the pre-test and N-gain were 0.002 for the pre-test significance and 0.000 for the N-Gain significance, which means  was rejected or there was a significant difference between the two groups because the significance value (p) was less than 0.05. Thus, it can be concluded that there is a significant influence of the application of the PBL learning model assisted by PhET simulations on the learning outcomes of eighth-grade students in the subject of light and optical instruments.

Abstract

Problem Based Learning (PBL) is a form of problem-based learning that is given to students to apply knowledge to issues or problems as a form of problem solving. Its integration with the STEM (Science, Technology, Engineering, and Mathematics) approach can train students to apply their knowledge in making designs as a form of problem solving related to the environment using technology. The purpose of writing this article is to find out the improvement, response and impact of students' curiosity by using the STEM-PBL learning model in science class. The method used is content analysis, with the principles of Preferred Reporting Items For Systematic Reviews and Meta Analysis (PRISMA). Based on the results of this study, it shows that students' curiosity towards STEM PBL in science classes shows significant results overall because the application of hands-on activities as a learning strategy is able to form various skills and provide positive results and even increase.
