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.

Abstract

This study aimed to develop and validate a Higher-Order Thinking Skills (HOTS) assessment instrument that leverages Wordwall activities embedded in Google Sites for teaching Newton’s Laws. A quantitative-descriptive design with an evaluative approach was employed. Nineteen Grade XI science students from Gajah Mada Private Senior High School were selected through purposive sampling. Item analysis examined validity, reliability, difficulty level, and discrimination power. Of the ten multiple-choice items constructed, five (50 %) met validity criteria, and the instrument achieved a reliability coefficient of 0.492, indicating adequate internal consistency. Difficulty indices classified three items as difficult and seven as moderate, while discrimination indices categorized two items as very good, three as good, one as fair, and four as poor. Students’ mean achievement score of 37.89 % suggests limited familiarity with HOTS-oriented questions. Pedagogically, embedding Wordwall in Google Sites enhanced learner engagement, reduced test anxiety, increased comfort, and simplified teachers’ post-test analysis through automated scoring. Consequently, the HOTS-based instrument is not only statistically sound but also practically effective for supporting digital physics instruction.

Abstract

This study aims to examine the physics concepts embedded in the traditional Indonesian games Tarik Tambang (Tug of War) and Balap Karung (Sack Race) through the application of Newton’s Laws. Conducted within the framework of ethnophysics, the research seeks to bridge scientific principles with local wisdom to foster contextual and engaging physics learning for students. A qualitative approach utilizing literature review was employed, analyzing various scholarly sources related to traditional games and their underlying physical principles. The findings reveal that Tarik Tambang illustrates Newton’s Second Law of Motion and the role of static friction. The game demonstrates how the acceleration of the opposing team is determined by the net pulling force and total system mass, while static friction is essential for maintaining player balance and traction. Additionally, strategies such as placing heavier players at the back enhance force generation and overall team performance. In Balap Karung, Newton’s Third Law and momentum significantly influence participants’ movements. The forward propulsion results from the backward action force exerted by the feet, which is met with an equal and opposite ground reaction force. Momentum affects the stability and speed of the jump, and friction between the sack and ground determines the efficiency of motion. This research highlights the pedagogical potential of traditional games in physics education. By contextualizing Newtonian mechanics through culturally familiar activities, students can develop a more concrete understanding of physical laws. The study recommends incorporating such games into instructional strategies to promote meaningful and culturally responsive science learning.
