Abstract

This study examines the impact of Ethno-Physics Learning on enhancing students’ critical thinking skills by integrating indigenous cultural knowledge into the physics curriculum. Traditional physics instruction, which often relies on rote memorization and passive learning, has been found insufficient in developing the analytical and problem-solving abilities necessary for both academic achievement and real-world applications. In contrast, Ethno-Physics Learning contextualizes abstract scientific concepts within culturally relevant frameworks, thereby fostering active inquiry and deeper cognitive engagement. Utilizing a quasi-experimental design with non-equivalent control groups, the research involved Grade 10 students from two classes. The experimental group received instruction on the topic of Work and Energy through Ethno-Physics Learning methods, while the control group experienced conventional lecture-based teaching. Both groups underwent pretesting and posttesting to assess their critical thinking skills across various dimensions, including analysis, inference, evaluation, explanation, and decision-making. Statistical analyses, incorporating tests for normality and homogeneity followed by paired samples t-tests, revealed that although improvements were noted in both groups, the experimental group exhibited significantly greater gains in critical thinking abilities. These findings suggest that integrating local ethnoscience into physics education not only makes scientific theories more accessible and meaningful but also cultivates the higher-order cognitive skills essential for effective problem-solving. The study highlights the transformative potential of Ethno-Physics Learning and recommends its incorporation into science curricula to enhance student engagement and learning outcomes in diverse educational settings.

Abstract

This study aims to determine the average improvement in high school students' critical thinking skills in physics learning by using Android-based interactive learning media. This research is quantitative in nature and employs a quasi-experimental pretest-posttest control group design. The research population consisted of all grade XI students at one school in the Garut District during the even semester of the 2024/2025 academic year. The study involved two classes: XI-J (the experimental group, n = 34 students) using Android-based learning media, and XI-I (the control group, n = 34 students) using Google Sites. The research instruments included student response questionnaires and pretest-posttest questions based on the critical thinking aspects defined by Ennis. Data were analyzed using tests for homogeneity, normality, a t-test, and the N-gain test, with the aid of SPSS. The questionnaire results showed an 81.24% acceptance level for the Android-based media, categorized as very good, while observations indicated that the implementation of the learning process reached an average of 90%. Pretest-posttest analysis revealed a significant improvement in students' critical thinking skills. The experimental group’s average score increased to 77.74 (categorized as good), while the control group achieved 65.59 (categorized as sufficient). The t-test yielded a significance value of 0.01 < 0.05; hence, H₀ was rejected and Hₐ was accepted, confirming a significant difference between the two groups. Based on these results, it can be concluded that the use of Android-based interactive media is proven to be more effective in improving students' critical thinking skills in the topic of static fluids compared to the use of Google Sites.

Abstract

The declining academic participation and study persistence among Indigenous Papuan students at Universitas Musamus highlight a critical issue that demands thorough investigation. While various external factors have been previously examined, this study specifically focuses on internal learning barriers, which remain underexplored in the context of higher education in Papua. The aim of this research is to explore key internal constraints affecting students' academic engagement, including motivation, comprehension of course materials, learning strategies, and personal or social disruptions. Employing a qualitative case study approach and Miles and Huberman’s interactive data analysis model, data were collected through open-ended questionnaires and semi-structured interviews with Indigenous Papuan students. The findings reveal a complex interplay of internal challenges such as low motivation, self-doubt, ineffective learning approaches, and physical or psychological discomforts that hinder students’ learning processes. These internal barriers not only reduce classroom engagement but also negatively impact students’ perseverance in completing their studies. The study underscores the urgent need for contextually responsive and sustained institutional support, such as academic and psychosocial mentoring programs, to foster holistic success among Indigenous Papuan university students.

Abstract

This study aims to develop and validate an ethnoscience-based practicum worksheet supported by virtual simulation tools to enhance culturally contextualized science learning. The integration of ethnoscience into science education responds to the need for pedagogical models that connect scientific concepts with students' local cultural knowledge, particularly in educational institution facing limited access to laboratory resources. Utilizing a research and development approach, the study was conducted through three main phases: preliminary investigation, design and construction, and evaluation and revision. The worksheet was structured to include scientific inquiry stages such as observation, hypothesis formulation, virtual experimentation, data analysis, and reflection. Expert validation was conducted using the Delphi method involving six experts in science education, ethnoscience, and educational technology. A Likert scale (1–5) instrument was used to assess content and construct validity, yielding average scores of 4.738 and 4.792 respectively, with a 95.83% agreement rate, indicating high validity and reliability. Suggestions from validators led to improvements in instructional clarity and contextual integration. The results confirm that the developed worksheet is pedagogically sound, technically feasible, and culturally relevant, aligning with 21st-century learning objectives that emphasize critical thinking, inclusivity, and digital literacy. This research offers a practical model for integrating ethnoscientific content with educational technology and contributes to the ongoing development of innovative, inclusive, and adaptive science education practices in Indonesia. Future applications may extend to diverse local contexts, supporting a more holistic and culturally grounded approach to science instruction.

Abstract

Drought has emerged as a critical issue in Tangerang Regency, Banten Province, primarily driven by the prolonged dry season, declining rainfall, and rising temperatures above average, all of which are exacerbated by the El Niño phenomenon. These conditions pose serious threats, including water shortages, reduced agricultural productivity, and the potential for widespread drought if left unaddressed. This study aims to map drought threat levels at the sub-district scale based on rainfall and temperature parameters. The integration of these two variables is essential, as drought is influenced not only by insufficient rainfall but also by elevated temperatures. Thus, a multivariable approach offers a more comprehensive and accurate spatial assessment. The analysis applied in this study involves scoring and overlay techniques for each contributing parameter. The results identify areas with varying degrees of drought threat—low, light, moderate, high, and extreme. Notably, 27.63% of the regency is classified under extreme drought risk, predominantly in the central to southern regions, due to the combination of very low rainfall and very high temperatures. The resulting drought threat map serves as a crucial reference for local governments, farmers, and the Regional Disaster Management Agency (BPBD) in planning effective mitigation strategies, early warning systems, and sustainable water resource management.

Abstract

Persistent misconceptions about temperature and heat often undermine students’ progress in thermodynamics.  This study therefore analysed Grade-11 learners’ conceptual understanding of these topics using a Four-Tier Multiple-Choice Diagnostic Test, an instrument that registers answer correctness, explanatory reasoning, and confidence on both selections.  A descriptive quantitative design was adopted.  Thirty students from class XI-34 of SMAN 3 Medan completed a five-item test that had been validated by experts and piloted for clarity; psychometric checks on the study sample confirmed good reliability (Cronbach’s α = 0.88) and adequate item validity (four of five items met the r-table criterion).  Responses were coded into four epistemic categories—Understands Concept (UC), Lacks Knowledge (LK), Misconception (MC), and Error (E)—and analysed. Findings show that overall achievement averaged 30 %, with individual scores ranging from 0 % to 80 %.  Across the entire data set, only 27.3 % of responses were classified as UC, while 19.8 % fell into LK, 45.3 % into MC, and 8.0 % into E.  Item-level analysis revealed that the highest misconception rate (73.3 %) occurred on the question concerning the effect of temperature on objects, whereas the phase-change item yielded the strongest understanding (46.7 % UC, 20 % MC).  These results confirm that misconceptions—especially the conflation of heat with temperature—constitute the principal barrier to coherent learning in this cohort. The study underscores the diagnostic power of four-tier instruments and recommends their wider use across other physics domains, enabling teachers to design confidence-sensitive interventions that directly target high-certainty errors and reinforce fragile correct ideas.
