Abstract

The low creative thinking ability of students in understanding physics concepts, especially in static fluid material, is one of the problems that needs attention in the learning process. Therefore, this study aims to determine how the Project Based Learning (PjBL) learning model that uses a scientific approach affects students' ability to think creatively about static fluid material. The research method used is a quasi-experimental design with a Nonequivalent Control Group Design. The research subjects consisted of two eleventh grade high school students, namely the experimental class using the scientific PjBL model and the control class using the Inquiry Learning model, each consisting of 30 students. The research instrument was a descriptive test consisting of eight questions developed based on Torrance's creative thinking indicators, including fluency, flexibility, originality, and elaboration. The data obtained were analyzed through normality tests, homogeneity, and N-gain calculations. The results showed that the average N-gain of the experimental class's creative thinking ability was 0.41 (medium category), higher than the control class which only reached 0.29 (low category). Specifically, significant improvements were seen in the fluency and flexibility indicators, while the originality and elaboration indicators also increased although relatively lower. Thus, it can be concluded that the application of the scientific PjBL model is more effective in improving students' creative thinking abilities compared to the Inquiry Learning model in static fluid learning. These findings are expected to contribute to the development of physics learning strategies oriented towards strengthening creativity, independence, and active involvement of students in the knowledge construction process.

Abstract

Physics learning is often considered difficult because students are unable to relate concepts to real-world problems they encounter. This condition results in low problem-solving skills among students, especially on contextual topics such as global warming. This study aims to determine the effect of the Problem Based Learning (PBL) model with the Teaching at the Right Level (TaRL) approach on students' problem-solving skills in global warming material. The research method used was quantitative with a quasi-experimental design of the pretest- posttest control group type. The research subjects consisted of 64 tenth-grade students at SMA Negeri 87 Jakarta, divided into an experimental class using the PBL-TaRL model and a control class using scientific learning. The research instrument was an essay test of problem-solving skills based on Polya's stages. The results showed that the average posttest score of the experimental class was higher than that of the control class. Based on the Ngain results, the N- gain was 0.58 (medium category) for the experimental group compared to 0.29 (low category) for the control group. Thus, the Problem Based Learning (PBL) model with the Teaching at the Right Level (TaRL) approach had a significant effect on students' problem-solving skills in global warming material.
