Abstract

Colloid learning is often difficult for students to relate to real-world phenomena, leading to a lack of conceptual understanding and critical thinking skills. One relevant local context for concretizing the concept of colloids is tofu waste treatment, which involves colloidal systems and environmental issues in the community. Integrating this ethnoscience context through Challenge-Based Learning has the potential to provide more contextual, meaningful, and authentic learning oriented toward problem-solving. This study aims to develop and demonstrate the impact of a Challenge-Based Ethnoscience e-book about colloids in the context of tofu waste treatment on improving students' conceptual understanding and critical thinking skills. This research method used Design and Development Research, consisting of three phases: design (needs analysis and product design), development (based on the 4STMD model), and evaluation (Students' critical thinking and conceptual understanding). Implementation was conducted with 30 eleventh-grade students. Critical thinking skills were measured using the Ennis framework, while conceptual understanding was assessed through context-based essay questions. Data were analyzed using the Wilcoxon test, Spearman correlation, and rank-biserial effect size. Results showed significant improvements in conceptual understanding and critical thinking skills, indicating consistent positive score changes across all participants. A very strong correlation was found between conceptual understanding and critical thinking skills, indicating a high degree of shared variance between the two. It can be concluded that the CBL e-book on ethnoscience related to colloid materials, developed according to the 4STMD, is a feasible and effective learning material for chemistry. This learning material aligns with the learning curriculum, is scientific, and organizes materials systematically through local wisdom, specifically in the context of tofu wastewater treatment, to enhance students' understanding of concepts and critical thinking skills.

Abstract

Technology and engineering literacy (TEL) is an essential competency for pre-service science teachers in meeting the demands of the modern workforce. However, existing TEL assessment instruments are often insufficiently aligned with developing country contexts. This study aimed to develop and validate a contextual Technology and Engineering Literacy Instrument (TELI) for pre-service science teachers. The instrument was developed based on the National Assessment of Educational Progress (NAEP) TEL framework and incorporated scenario-based assessments reflecting real-world problems. A psychometric instrument development and validation design was employed. Content validity was evaluated by five experts, and field testing involved 132 pre-service science teachers in Riau Province, Indonesia. Rasch model analysis was used to examine construct validity, item fit, and reliability. The results demonstrated high content validity and acceptable construct validity, item fit, and reliability. These findings indicate that TELI is a valid, reliable, and contextually relevant instrument for assessing TEL competencies. The study concludes that TELI can support authentic assessment in science teacher education and provide a practical tool for evaluating and improving technology and engineering literacy in developing country contexts.

Abstract

This research investigates the relevance of chemistry content and context for vocational high school students majoring in Metal Casting Technology to bridge the gap between the general science curriculum and practical industrial applications. Employing an evaluative approach, data were gathered through documentation studies, in-depth interviews, and expert reviews at SMK Negeri 4 Kota Sukabumi, and subsequently analyzed using Mayring’s Qualitative Content Analysis (QCA). The findings reveal 16 essential chemistry topics that are highly required by the industry but currently unaccommodated in the curriculum, such as precise material composition control, interfacial chemistry in mold coating, and the influence of alloy composition on metal microstructure. Based on these insights, a contextual teaching material outline was formulated to integrate chemical theory with the practical metal casting industry. The development of adaptive learning modules is crucial for enhancing curriculum alignment and boosting graduate workforce readiness.

Abstract

The process of generalisation and the formation of knowledge is often debated about the scientific methods of deduction and induction. There is a dualism between the two. A philosopher of falsification theory, Karl Raymond Popper, criticised induction theory and supported deductive theory, while philosopher John Stuart Mill emphasised the importance of induction in scientific reasoning, especially the use of enumerative induction. In this article, the author tries to briefly explain the urgency of John Stuart Mill's thought in science. Using the library research method, using relevant books and journal articles. Through this research shows the relationship between enumerative induction, coherence and generalisation by John Stuart Mill's can be assembled that enumerative induction shows the consistency pattern of individual cases obtained from repeated observations, where these individual cases in addition to being consistent also have coherence with each other so that a coherent belief system pattern is formed and then forms a generalisation or new science. Although this kind of induction assumption has a level of strength of proof that is difficult to refute. There are still limitations to inductive generalisation, namely the possibility that future discoveries will show that our belief in our current conclusions is incorrect.
