Abstract

The study was a qualitative research, employing ontological and epistemological approaches to explore the philosophy of global warming. Questionnaires and interviews were conducted with students and teachers, which examined whether the current implementation of global warming education aligns with ontological and epistemological perspective and propose recommendations to improve global warming education in science lesson. The ontological perspective begins with literature review that examines the unique of greenhouse gasses characterized as heat traps, focusing on microscopic view of vibrational modes of molecules and their impact on global warming. Furthermore, the epistemological perspective explored how researchers validate the scientific understanding of global warming and its impact on the environment. In addition, the questionnaire result showed that various teaching method, such as experiment, video, PhET simulation, teacher explanation, and internet exploration, were used. But most of students never see the microscopic view of vibrational greenhouse gas molecules that trap the heat. Students also did not evaluate and validate the influence of greenhouse gas concentration on increasing system temperature as epistemological approach. Therefore, the lesson of global warming especially the concept of greenhouse effect, needs an approach that integrates ontological and epistemological perspective, such integrating modeling or simulation in microscopic scale into experimental activities (bifocal modeling).

Abstract

This research aims to explore the ethnoscience of the Terbang Gembrung percussion instrument of the indigenous community in Kampung Naga, Tasikmalaya, West Java, and its potential as a local context in physics education. The Terbang Gembrung percussion instrument of Kampung Naga employs an acoustic membrane of goat leather with an air column of albasia or manglid wood. The research methodology encompasses qualitative descriptive methods, including literature study and interviews, as well as observation methods involving the measurement of sound frequency generated using the Decibel X smartphone application under conditions where the instrument produces typical sound. The Terbang Gembrung tradition holds religious value and is commonly performed during significant celebrations such as Eid al-Fitr, Eid al-Adha, and other religious festivities. Based on the observation results, it was found that four types of percussion instruments produce sound frequencies at four harmonic levels according to the membrane size. The first harmonic has a frequency of approximately 199.0 Hz, the second harmonic around 211.5 Hz, the third harmonic approximately 231.5 Hz, and the fourth harmonic around 261.0 Hz. The design of the percussion instrument is in the form of a half-spherical cone, with the cross-sectional area decreasing from the membrane to the end of the air column. The potential application of science principles to the Terbang Gembrung percussion instrument makes it a cultural artifact that can serve as a local context in physics education at the high school level, focusing on the topics of sound waves, especially sound intensity and sound frequency.

Abstract

The science teacher development program on STEM Learning using Arduino was conducted to enhance science teacher competencies in designing and implementing a 21st-century skills-based teaching approach. This study implemented research evaluation with Context, Input, Process, and Product (CIPP) to determine the drivers that supported and enhanced the program's effectiveness and address the barriers that obstruct teachers' competencies. The methodology employed in this study is both qualitative and quantitative methods. Qualitative methods gather data through observations, interviews, and document analysis. In addition, quantitative methods involve calculating the percentage of participants who complete the training program. Interviews and document studies in context evaluation help determine if program objectives are relevant to teachers' needs and aligned with the curriculum. Observation, interview, and document study were employed to evaluate input, process, and product and complement with quantitative data. The result shows that the science teacher development program is highly relevant today in enhancing teachers' competencies to design 21st-century skills-based teaching. However, some improvements are still needed to support the drivers and eliminate the barriers to make the program more effective. Some drivers, such as participants' motivation, well-organized content, competent facilitators, and sufficient resources, are assets to continue the program. However, the revision of the indicator objectives program, the selection process of participants, the time to conduct the workshop session, guidance, and content representation are essential to note.

Abstract

In this study, a Technology Enhanced Worksheet Inquiry (TEWI) learning resource was developed as an innovative tool to support inquiry-based science learning. The first version, TEWI v1.0, was produced in two formats: a digital book in .epub format and a paper-based version equipped with QR codes to integrate digital content into printed worksheets. The implementation of TEWI v1.0 in classroom learning resulted in a normalized gain score of 59.02%, indicating that this version falls into the average effectiveness category in improving student learning outcomes. Further analysis of the worksheets shows that TEWI v1.0 provides a promising alternative to facilitate meaningful learning experiences, particularly in strengthening students’ scientific practices, inquiry processes, and intellectual skills. The integration of technology within the worksheet design also supports greater interactivity and accessibility to multimedia learning resources. However, several aspects still require improvement, especially in simplifying the explanation of concepts and refining the sense-making process to ensure better clarity for students. These findings suggest that TEWI v1.0 serves as a valuable foundational prototype, but continued development and revision are needed to optimize its pedagogical effectiveness.
