Abstract

Analytical study of homogeneous charged volumetric hemisphere electric field along its symmetry axes is presented in this article. Solution was obtained by two different ways; on one hand, superposition of finite thickness disks with increasing radius, and, on the other hand, straightforward integration of finite volume elements in cylindrical coordinates. The same result is obtained in both cases. Additionally, a numerical solution based on the electric field created by a random distribution of discrete charges inside the hemisphere was calculated to check the analytical solution. Concordance between the analytical and numerical solutions was found. The interest of this theoretical result at electronics investigation field resides on its utility to determine the capacity of two opposite hemispheres capacitor system.

Abstract

Students' low concept mastery of Momentum and Impulse leads to difficulties applying these concepts in everyday life. Solutions are needed to address these challenges and enhance students' concept masteryof Momentum and Impulse. Integrating phenomena into active learning is crucial for improving students' concept mastery. This research aims to enhance students' understanding of Momentum and Impulse through an integrative active learning model. An experimental study with a one-group pretest-posttest design was conducted on 30 grade 11 students. The results showed that technology-based active-integrative learning effectively increased students' concept mastery of Momentum and Impulse concepts, particularly within the medium category. Students' understanding at higher levels (levels 2 and 3) also saw significant improvement. Therefore, adopting technology-based active-integrative learning is a vital step in this direction.

Abstract

This study aims to evaluate the effectiveness of Islamic literacy-based STEM (Science, Technology, Engineering, and Mathematics) multimedia in enhancing students' computational thinking skills in a basic physics practicum course. The research employed a quasi-experimental design with a mixed-methods approach, involving two groups: an experimental group that received instruction through Islamic literacy-based STEM multimedia and a control group that used conventional methods. The instruments used included a computational thinking skills test, designed to measure four primary indicators: abstraction, algorithm, decomposition, and pattern generalization, as well as in-depth interviews to explore students' learning experiences. Quantitative data were analyzed using a t-test to determine significant differences between the two groups, while qualitative data were analyzed thematically. The findings indicated a significant improvement across all computational thinking indicators in the experimental group. Qualitative analysis further revealed that integrating Islamic literacy deepened students' understanding of physics concepts, offering a spiritual context that enriched their learning experiences. These findings suggest that Islamic literacy-based STEM multimedia is not only effective in enhancing computational thinking skills but is also well-suited for educational contexts that integrate technology and spirituality. The implications of this study support the development of a holistic curriculum in STEM education aligned with spiritual values.

Abstract

The aim of this study is to evaluate the level of students' scientific reasoning skills in the subject of static fluids. This research was conducted through a descriptive quantitative survey. The study involved 110 high school students from Grade 12 in Malang, Indonesia, during the 2023/2024 academic year. Six scientific reasoning skill test instruments were used to collect data. The data collection was carried out using six test instruments, covering Control of Variables, Conservation Reasoning, Probabilistic Reasoning, Correlational Reasoning, Hypothetical-Deductive Reasoning, and Proportional Reasoning, with a Cronbach's alpha of 0.744, indicating high reliability. The data were analyzed using descriptive statistical tests, followed by classification of skill levels based on static fluid subtopics and scientific reasoning indicators. According to the survey results, 33% of students demonstrated low-level scientific reasoning skills. Based on the static fluid subtopics, the highest to lowest scores were found in Archimedes' Principle (35%), hydrostatic pressure (34%), and Pascal's Law (31%), all within the low category. In terms of scientific reasoning sub-indicators, the highest to lowest scores were observed in Hypothetical-Deductive Reasoning (42%) and Probabilistic Reasoning (41%), categorized as moderate, while lower scores were found in Correlational Reasoning (39%), Conservation Reasoning (29%), Control of Variables (26%), and Proportional Reasoning (24%), all within the low category. The results suggest that students struggle with analyzing factors affecting sinking, floating, and buoyancy; identifying variables influencing hydrostatic pressure; and performing mathematical calculations related to force and cross-sectional area comparisons. These findings indicate that instruction needs to be strengthened to help students improve their scientific reasoning, particularly in the indicators of Conservation Reasoning, Control of Variables, and Proportional Reasoning, which remain low. To maximize the effectiveness of this research, educators should employ active learning models such as the 7E Learning Cycle Model integrated with the STEAM approach, which can directly engage students.

Abstract

This research examines the application of the fast forward method to single spin with Rabi frequency. In this study, the electron spin dynamics are examined by accelerating adiabatic quantum dynamics. Through the concept of adiabatic will be obtained unchanged state of the system, at the beginning and end of the evolution of the system. This study aims to obtain an additional Hamiltonian on the concept of accelerated adiabatic quantum dynamics on single spin. The method used is the fast forward method developed by Masuda and Nakamura. The result of this research is to obtain the additional Hamiltonian “equation 54” and the driving magnetic field through the fast forward method “equation 56”. The fast forward method is applied by first obtaining the eigenvalues of the Hamiltonian system. Furthermore, by reviewing the lowest energy state (ground state). It is concluded that this study obtained an additional Hamiltonian term with a driving magnetic field that ensures that a single spin can move from the initial state to the final state in a short time, while maintaining the characteristics of each energy level in the system.

Abstract

Global warming remains a critical global challenge that affects multiple dimensions of life and demands immediate, coordinated action. Peatlands, which have a dual capacity to either mitigate or exacerbate global warming, are increasingly subject to degradation. Addressing this issue requires a transformative approach to science education, emphasizing sustainability. This transformation can be achieved through the development of e-worksheets that integrate the PISA 2025 Science Framework and Education for Sustainable Development (ESD). This study aims to design e-worksheets for science education that incorporate these frameworks, with a focus on elucidating the role of peatlands in the global warming phenomenon. The research adopts a development research methodology based on the Rowntree model, involving 12 tenth-grade students from a state high school in South Sumatra during the 2023/2024 academic year as participants in the product evaluation phase. The evaluation method is driven by Tessmer's formative evaluation paradigm, which includes self-evaluation, expert review, one-to-one evaluation, and small group evaluation. Interviews, walkthroughs, and questionnaires are among the data collection methods used. The analysis results show that the expert review phase produced an average validation score of 94.2%, which is classified as extremely valid. Furthermore, the one-to-one and small group evaluation stages yielded average practicality values of 86.25% and 97.5%, respectively, classifying them as extremely practical. These findings suggest that the produced e-worksheets, which are geared toward the PISA 2025 Science Framework and ESD, are both valid and practicable for classroom use, particularly in terms of improving students' understanding of the essential role of peatlands in the global warming catastrophe.
