Climate change and weather are now problems that affect the whole world and are bad for the environment and for people's lives. Sadly, a lot of high school students still don't understand the basics of climate change because the material is too abstract and hard to understand. For example, they think that daily weather is a form of long-term climate change. To solve this, a Problem-Based Learning (PBL) physics module was made for high school students to teach them the basics of climate change and weather. The module was created to follow the Merdeka Curriculum's Deep Learning principles of being mindful, meaningful, and fun. This study employed an R&D methodology utilizing the ADDIE model. Three experts (in material, curriculum, and pedagogy) were involved in the validation process. 23 students were used in individual and small group trials to test practicality. The average validity score was 86.78% and the average practicality score was 82.82%. Both of these scores are in the Very Valid and Very Practical ranges. These results show that the module is a good choice for use as a contextual teaching tool that helps with understanding concepts, engaging the mind, and being aware of the environment.

This work investigates the application of Physics-Informed Neural Networks (PINNs) for numerical solutions to the time-independent Schrödinger equation of the quantum harmonic oscillator in one, two, and three spatial dimensions. Fully connected neural architectures are constructed to approximate wavefunctions over finite symmetric domains, while the corresponding energy eigenvalues are treated as trainable parameters. The training strategy utilizes randomly sampled interior points to enforce the Schrödinger operator residual and boundary points to impose vanishing wavefunction constraints. For the 1D quantum harmonic oscillator, the learned ground-state wavefunction yields an energy of E = 1.2939 after 12,000 iterations. In the 2D configuration, convergence is achieved at E = 2.1352 within 14,000 iterations, whereas the 3D model attains E = 2.6377 after 12,000 iterations. These values agree with the expected trend of increasing ground-state energy with dimensionality, although deviations from exact analytical values indicate that PINNs may experience optimization challenges and sensitivity to sampling density and boundary enforcement. Despite these limitations, the trained models successfully capture the characteristic spatial symmetries and Gaussian-like envelope of harmonic oscillator eigenstates across all dimensions. These findings demonstrate that PINNs offer a flexible, mesh-free alternative for solving stationary quantum systems, particularly when analytical or conventional numerical approaches become impractical. The method shows strong potential for higher-dimensional quantum applications, even though further refinement such as improved sampling, loss balancing, and network depth remains necessary to suppress residual error and enhance eigenvalue accuracy.

Purpose of the study: The low level of science literacy among Indonesian students requires innovative and contextual learning approaches. This study aims to develop and test the validity of an Ethnoscience-Based Teaching Module on the subject of Vibrations and Waves. The uniqueness of the module lies in its deep integration of the local wisdom of East OKU Regency as a learning context to bridge abstract scientific concepts with the cultural reality of students. Methodology: This study used the Research and Development (R&D) method with a 4-D model, limited to the Develop stage. Validation was carried out by four experts (material, media, language, and culture) using adapted assessment instruments. Quantitative data were analyzed using Aiken's V coefficient. Main Findings: The developed ethnoscience-based teaching module was declared "Highly Valid" with an average Aiken’s V score of 0.90. All validation aspects scored highly: subject matter (0.90), media design (0.88), language (0.85), and cultural integration (0.95). The module is therefore feasible for further testing. Novelty/Originality of this study: The developed module has met the eligibility criteria in terms of content, design, language, and authentic cultural integration. The implication of this research is the availability of valid and contextual teaching materials, which are ready to be further tested for their effectiveness in learning to improve science literacy while building students' cultural awareness.

Purpose of the study: The study evaluates the effectiveness of Problem-Based Learning (PBL) in improving students’ critical thinking mastery of pressure concepts by analyzing the proportional distribution of mastery rather than relying solely on mean score comparisons. Methodology: A quasi-experimental pretest-posttest nonequivalent control group design was employed with 60 eighth-grade students selected through purposive sampling from intact classes. Students were assigned to a PBL group (n=30) or a conventional instruction group (n=30). Critical thinking was measured using a validated 10-item multiple-choice test adapted from Ennis’s indicators. Baseline equivalence was tested with the Mann–Whitney U test, within-group mastery shifts with McNemar’s test, and between-group distributional differences with the Chi-square test of independence. Reliability was confirmed (Cronbach’s α = 0.86). Main Findings: The PBL group achieved a significantly higher mastery rate (83%) compared to the conventional group (60%), χ²(1) = 4.02, p = 0.045, with a moderate effect size (Cramer’s V = 0.26). McNemar’s test confirmed a statistically significant mastery transition within the PBL class (p < 0.05). The strongest gains occurred in analytical explanation and inferential reasoning dimensions. Novelty/Originality of this study: Analyzing mastery distribution reveals equitable learning outcomes that mean comparisons obscure. The findings demonstrate that PBL systematically shifts categorical achievement toward competency thresholds, particularly in higher-order cognitive dimensions. In practice, this supports the adoption of distributional analysis in classroom assessment. The study’s novelty lies in its methodological shift from continuous mean scoring to categorical mastery distribution, offering a more pedagogically relevant framework for evaluating instructional equity.

Socioscientific Inquiry-Based Learning (SSIBL) requires instructional continuity across contextual exploration, scientific inquiry, evidence construction, argumentation, and assessment. However, existing digital learning environments often support these activities in isolation, resulting in fragmented pedagogical processes. This study proposes a pedagogically driven framework for designing a Socioscientific Inquiry-Based Learning (SSIBL) digital platform through the systematic identification of instructional needs, synthesis of cross-phase instructional functions, derivation of system-level design requirements, and development of an architectural framework. A design-oriented requirement elicitation approach was employed involving 45 senior high school students and six physics teachers. Data were collected using structured questionnaires covering six phases of the SSIBL workflow and analyzed through descriptive analysis, cross-phase pattern identification, instructional function synthesis, requirement translation, and architectural framework development. The findings revealed consistently high instructional needs across all SSIBL phases and identified four cross-phase instructional functions: Epistemic Structuring, Evidence Construction, Deliberative Anchoring, and Orchestration Visibility. These functions informed the derivation of system-level design requirements and the development of an architectural framework that preserves instructional continuity throughout SSIBL. The study contributes a transparent pedagogically driven framework that bridges instructional theory and educational technology design, providing a conceptual foundation for future platform development and design-based research.

This study examines the integration of Ethno-STEM with differentiated learning through bibliometric analysis (15 Scopus documents, 2015–2024) and systematic literature review (15 articles, 2015–2024). Bibliometric results reveal a focused research landscape dominated by United States institutions, with steady publication growth post-2020. SLR synthesis identifies key pedagogical themes, including culturally responsive pedagogy, personalized learning, and the necessity of culturally adaptive teaching. The integration of these approaches fosters inclusive, student-centered environments that value local wisdom. However, challenges persist in teachers' culturally responsive STEM literacy and the design of diverse learning products. This research contributes to the development of the Differentiated Ethno-STEM Knowledge (DESK) framework, providing a systematic roadmap for teacher professional development. Conclusively, these findings offer actionable insights for sustainable education policy, directly advancing Sustainable Development Goal 4 (Quality Education) through contextually relevant and inclusive 21st-century learning strategies.

Understanding high-dimensional spaces, particularly the fourth dimension, remains a major conceptual challenge in quantum physics education due to their abstract mathematical nature and the limitations of conventional visualization approaches. Although four-dimensional quantum systems have been extensively explored in theoretical and experimental physics, their pedagogical visualization remains limited and rarely integrated with computational modeling for instructional purposes. This study aims to develop and systematically evaluate a computational visualization framework for a four-dimensional particle in a box quantum system by: (1) constructing a numerical model using Python-based simulation, (2) implementing explicit dimension-reduction techniques to project 4D probability distributions into 3D and 2D representations, and (3) analyzing the structural and probabilistic features preserved in these projections. The results show that the projected visualizations preserve key signatures of the fourth dimension, demonstrated by a ground-state energy relative error of 0.14% and normalization accuracy of 99.98%, indicating high computational reliability. The resulting heatmaps and tesseract-based geometric representations provide interpretable visual structures that support spatial reasoning in quantum learning contexts. The novelty of this study lies in the explicit integration of high-dimensional quantum modeling, systematic dimension-reduction, and data-driven visualization within a single pedagogical framework, which transforms abstract four-dimensional quantum formalisms into accessible instructional representations. This study contributes a computationally grounded instructional model that supports the development of quantum literacy and conceptual understanding in modern physics education.
