Abstract

This study aims to visualize the temperature distribution on metal plates by solving elliptic differential equations using the help of the Microsoft Excel program. Many physics problems have limited analytic solutions so a numerical solution is needed. One of them is about the temperature distribution on a homogeneous metal plate in a steady-state conditionThe equation of heat flow in steady-state conditions is an elliptic partial differential equation (PDE). By solving this equation, we will have a numerical model of the plate that can be a mesh with a certain temperature point. Each point has been known to calculate the temperature value. The temperature value influenced. The Temperature value influenced borders on the plate and the presence of heat generation. The edge of the plate can be a constant temperature, a convection zone with the outside air, or an isolated edge. This model is then processed using Microsoft Excel with the iteration calculation until the temperature distribution value is obtained. The results obtained a graphical visualization of temperature distribution on the plate.

Abstract

Learning physics on the topic of thermodynamic processes requires media and learning tools that match the characteristics of the material in order to support the learning process. Therefore, Curipod-based media and learning tools that are developed need to be validated to ensure their feasibility before being implemented in learning. This study aimed to determine the validity of interactive learning media based on the Curipod platform and learning devices on thermodynamic processes material. Curipod was developed as an alternative interactive learning medium to support physics learning. The selection of this material was based on the abstract nature of physics concepts, which require dynamic visualization to facilitate understanding. This study employed a Research and Development (R&D) approach using the comprehensive ADDIE model, with the research limited to the Development stage. Data were collected through validation sheets assessed directly by experts from the Department of Physics, Faculty of Mathematics and Natural Sciences, Universitas Negeri Gorontalo.

Abstract

This study aimed to analyze Biology education students’ conceptual difficulties in work and energy using the Rasch Model. A descriptive quantitative approach with a diagnostic survey design was employed. The participants were 21 Biology education students who had learned the topic of work and energy. The instrument consisted of 15 diagnostic multiple-choice items scored dichotomously, with 1 indicating a correct answer and 0 indicating an incorrect answer. The data were analyzed using the Rasch Model to examine instrument quality, item fit, item difficulty, Wright Map, score-category monotonicity, and students’ conceptual difficulty patterns. The results showed that students’ average ability was higher than the average item difficulty, with a mean person measure of 1.61 logits. However, the person reliability of 0.08 and person separation index of 0.30 indicated that the instrument had limited ability to distinguish students across different ability levels. The most difficult items were Q14, Q3, Q11, Q13, and Q15, which were related to the application of work, potential energy, and mechanical energy conservation. In contrast, Q2, Q4, Q5, and Q9 were the easiest items because they mainly assessed basic conceptual recognition. These findings indicate that students’ main difficulties were not in recognizing basic terms but in applying and integrating work and energy concepts in physics contexts.

Abstract

Problem-solving skills are important skills in physics learning. However, learning practices in schools are still dominated by conventional methods that are less able to accommodate differences in learning styles and student readiness levels. Therefore, the application of the Problem Based Learning (PBL) model with a differentiated approach is seen as effective in improving students' critical, creative, and analytical thinking skills, especially in sound wave materials. This study uses a quantitative method with a quasi-experiment design. The subject of the study was grade XI students of SMA Negeri 1 Kabila which consisted of one experimental class and two replication classes. The research instrument is in the form of pretest and posttest essay questions to measure problem-solving skills. Data analysis was carried out through Liliefors normality test, Alpha Cronbach reliability, paired sample t-test, and N-Gain calculation. The results of the study showed a significant increase in the average pretest and posttest scores in all classes. The normality test states that the data is normally distributed, while the reliability test confirms that the instrument is classified as reliable. The hypothesis test proved that H? was rejected, with an average N-Gain of more than 0.7 which meant a very high increase. Thus, the application of the differentiated PBL model has been proven to have a positive effect on problem-solving skills and encourage students to be more active, involved, motivated, and able to solve contextual problems according to learning styles.
