Wed, 11 Dec 2024 00:00:00 +0700

Purpose of the study: This research aims to develop learning media using computer-based collision material in the context of the traditional game of marbles.

Methodology: This research is a Research and Development study using the ADDIE research design. The research was conducted at MA Al-Fatah Palembang using instruments in the form of interviews and questionnaires for data collection. Interviews were conducted with physics subject teachers at MA Al-Fatah Palembang. The questionnaire was given to media expert validators, material expert validators, teachers and students to see the validity and practicality of media use.

Main Findings: The result of this research is a learning media product using computer-based collision material in the context of the traditional game of marbles which meets the valid and practical criteria. The results of media expert validation that have been carried out show percentages of 91,7% with very valid categories. The material expert validation results show a percentage of 92.8% with a very valid category. The results of the limited trial showed that the percentage of assessments from physics subject teachers was 89,2% in the very practical category and students' responses to the use of learning media showed a percentage of 87.3% in the very practical category.

Novelty/Originality of this study: The main novelty of this study lies in utilizing a traditional game as a contextual and engaging framework to teach abstract physics concepts, such as collisions, in a more comprehensible way.

Purpose of the study: This study aims to analyze senior high school students' critical thinking skills in thermodynamics and explore gender-based differences in these skills.

Methodology: A quantitative approach was employed with purposive sampling involving 132 students (34.1% male, 65.9% female) who had studied thermodynamics with the same teacher. Data were gathered using five essay questions designed to assess critical thinking components, including analysis, evaluation, inference, deduction, and induction. The collected data were analyzed to determine the level of critical thinking skills and potential differences between genders.

Main Findings: The results showed that students’ critical thinking skills were generally low across all components: analysis (36.2%), evaluation (30.0%), inference (19.8%), deduction (28.3%), and induction (32.0%). While differences in critical thinking skills between male and female students were observed, they were not statistically significant.

Novelty/Originality of this study: This study provides a detailed analysis of students' critical thinking skills in thermodynamics, highlighting specific weaknesses in key components. It offers a new perspective by examining gender-based differences in critical thinking, which are rarely explored in the context of physics education. The findings serve as a foundation for designing targeted educational strategies to address these deficiencies and improve critical thinking skills in science learning.

Analyzing Ohm's Law: Comparison of Current and Resistance in Series and Parallel Circuits

Tue, 17 Dec 2024 11:05:39 +0700

Purpose of the study: The purpose of this study is to analyze and compare the relationship between current and resistance in series and parallel circuits, and to verify the accuracy of Ohm's Law through experimental measurements and theoretical calculations.

Methodology: This study uses a Pre-Experimental Design (One-Group Post-Test Only Design), involving 10 series and 10 parallel circuits with resistors of varying values. Measurements of current and resistance were taken using a digital multimeter and ohmmeter. Data collection occurred at three time points (start, 5 minutes, 10 minutes). The data was compared with theoretical values based on Ohm's Law.

Main Findings: The experiment showed that in a series circuit, the current increased proportionally with the applied voltage, consistent with Ohm's Law. In parallel circuits, the current also increased with voltage, but at a higher rate compared to series circuits. The resistance measured in both circuit types was consistent with theoretical calculations, with minor percentage errors observed in both configurations.

Novelty/Originality of this study: This study offers a fresh perspective by analyzing the application of Ohm’s Law in both series and parallel circuits, comparing real experimental data with theoretical calculations. It advances existing knowledge by providing a practical verification of theoretical concepts, enhancing understanding of current distribution and resistance effects in different circuit configurations, which can benefit students and professionals in electronics.
