Abstract

This study aims to analyze students' understanding of energy concepts through the PhET simulation in the case of the Skate Park. Energy concepts, including kinetic energy, potential energy, and mechanical energy, often present challenges in physics education, particularly in the context of visual and interactive comprehension. In this study, the PhET "Energy Skate Park" simulation was used to observe energy changes in objects moving along a skate park track at various heights. The study involved high school students conducting experiments using this simulation to understand the basic principles of physics related to energy changes. Data were collected through direct observations and pre-test and post-test quizzes to assess the improvement in students' understanding of energy concepts. The results showed that using the PhET simulation significantly helped students understand the changes between kinetic energy, potential energy, and mechanical energy in a more tangible and visual context. The average post-test score (86.67) demonstrated an increase of 24 points compared to the pre-test score (62.67), with the standard deviation decreasing from 7.91 to 6.05, indicating a more consistent understanding among students. The simulation effectively assisted students in building conceptual schemas through interactive visualization and virtual experiments, aligning with constructivist theory, experiential learning, and multimedia learning theories.The simulation also demonstrated its potential to enhance student engagement and their ability to apply physics concepts to real-life situations.

Abstract

Abstract: This study aims to develop and validate science teachers' perception of the free fall motion practicum device based on Arduino UNO and the Phyphox Application through the Science Subject Teachers' Deliberation (MGMP) forum. This research method applies the research and development (RnD) method with the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. The first step is the analysis of the needs of the problem of misconceptions of free fall motion and the selection of media to be developed; the second step is the design of the development of the device used, namely Arduino UNO and the Phyphox Application in the form of a digital sketch before continuing to the development process. The third step is the development of the Arduino UNO and Phyphox free fall motion kit prototype; the fourth step is the implementation of a data collection trial carried out by a group of volunteer students in the free fall motion practicum and continued with the introduction of the device through the MGMP Science forum. The final evaluation activity is the collection of data from the science teacher perception questionnaire on the developed tool and validating the tool. The results of the testing and development show that Adruino has a slightly lower accuracy level than the phyphox application. These results were obtained from practical activities by a group of students. This may be influenced by development factors and technical settings that can affect the accuracy level of the Adruino practical tool. Each tool has its advantages; Adruino is suitable for training students in coding programming and technology-based learning according to the needs of the 21st century. Meanwhile, Phyphox offers practicality and fast and efficient use. Through practicality testing, both tools provide good and relevant results to improve the quality of learning, especially in the misconception of free fall motion.     Keywords: free fall motion, arduino UNO, phyphox application.

Abstract

Critical thinking and problem-solving skills are essential components of 21st-century education goals. Weak problem-solving and higher-order thinking skills (HOTS) can become problematic for students studying physics, particularly in the context of magnetism. To address this issue, efforts are being made to improve physics problem-solving skills through the application of problem-based learning (PBL) and HOTS. The study aims to determine whether students' physics problem-solving skills are better when using PBL-HOTS compared to PBL alone. Additionally, the study aims to determine the improvement and profile of physics problem-solving skills according to Heller after the application of PBL-HOTS on magnetism material. The study employed a mixed-methods sequential explanatory pre-test post-test control group design. The participants were ninth-grade students from SMP Negeri 1 Kersana during the 2021/2022 academic year. The sample was selected using purposive sampling, with Class IX A as the experimental group and Class IX C as the control group. Data was collected using a physics problem-solving test, including descriptions, interviews, and post-test documentation checks. The t-test results indicate that students who applied PBL-HOTS had better physics problem-solving skills than those who applied PBL. Additionally, the N-Gain test showed a moderate increase in students' physics problem-solving skills after the application of PBL-HOTS, with an average N-Gain score of 0.4785. The results of interviews and examination of posttest documentation support Heller's profile of students' physics problem-solving skills. This includes indicators of focusing on the problem (84.69%), describing physics concepts (70.94%), planning solutions (87.81%), implementing problem-solving plans (95.63%), and evaluating solutions (46.88%).
