Abstract

This study presents an investigation of the use of STEM Project-Based Learning (PjBL-STEM) as a treatment in the experimental class compared to conventional learning in the control class in improving students' critical thinking skills and learning motivation. The focus of the study was Pascal's Law lessons with a special project in the form of developing a simple hydraulic jack. So far, science learning carried out in schools has made students complain, as it is still rote, teacher-centered, unrelated to real-life developments, and rarely integrates technology. This study, therefore, used a quantitative method with a quasi-experimental design involving 60 ninth-grade students in Pasaman Regency who were evenly divided into control and experimental classes using purposive random sampling techniques. Data was collected through a questionnaire on critical thinking skills and learning motivation, after the implementation of PjBL-STEM. The results demonstrated a significant difference between the two groups, with an independent T-test yielding a value of 0.24 for critical thinking skills and 0.33 for learning motivation. The PjBL-STEM model has been proven to improve student's critical thinking skills with an N-Gain of 0.46 (moderate category) and students' learning motivation with an N-Gain of 0.49 (moderate category).      Keywords: critical thinking skills, learning motivation, Pascal's Law, PjBL-STEM. DOI: http://dx.doi.org/10.23960/jpmipa/v25i4.pp1976-1999

Abstract

This research aims to provide a bibliometric literature review regarding the trends of entrepreneurial thinking (ET) research in science education in 2014-2023. In this research, five main stages were carried out in bibliometric literature: determining topics and keywords, searching databases according to keywords, refining the database, compiling statistical data, and analyzing data. Search results from the scopus.com document database using the keywords "entrepreneurial thinking" and "science education" obtained 89 articles, which were then analyzed for completeness and statistical data. Data that have gone through the refinement stages are stored in the form of Research System Information (RIS) and analyzed using VOSviewer software to obtain visualization of the data. The results of the bibliometric review show that the entrepreneurial thinking research trend linked to science education continues to experience development with a focus on research studies on the integration of entrepreneurship in science and engineering, as well as the development of skills related to entrepreneurship through science, including entrepreneurial character, entrepreneurial intention, and entrepreneurial thinking. In more specific science education, entrepreneurial thinking has begun to be developed through STEM and design thinking since 2018. Another bibliometric review shows that research on ET still needs to be studied, especially in science teaching, which is linked to strategies, approaches, media, and teaching models. The results of the bibliometric review show that ET in science education has many opportunities for research development that can be studied further.

Abstract

One of the important principles in the success of learning activities is that educators need to pay attention to students' preconceptions before designing learning designs, because this will provide direction in compiling learning materials and strategies to achieve learning goals. This study aims to identify the preconceptions of preservice chemistry teachers as a basis for developing a didactic design on the topic of plant pigments separation which is one of the materials discussed in analytical chemistry II lectures. This research uses descriptive methods with participants were 36 pre-service chemistry teachers at one of the state universities in Pekanbaru City. This descriptive study used a diagnostic test in the form of an essay which totaled 19 questions. Based on the results of preconception analysis, it was identified that most of the students experienced learning barriers mostly in the following sub-discussions: (1) types of green solvents; (2) benefits of eutectic solvents; (3) the relationship of eutectic solvent with principles of green chemistry; (4) the process of making eutectic solvents; (5) experimental stages of plant pigment extraction; (6) processes that occur during extraction; and (7) extraction techniques. So it can be concluded that students do not yet have sufficient basic knowledge because students are not yet able to answer questions in most contexts on the topic of separating plant pigments

Abstract

Heavy metal pollution in aquatic systems increases the need for sustainable and efficient natural adsorbent materials, and carrageenan extracted from Eucheuma cottonii, which contains O–H, S=O, C–O–S, and 3,6-anhydrogalactose functional groups, offers strong potential for binding metal ions. However, the adsorption efficiency of natural carrageenan for Copper (Cu2+) and Cadmium (Cd2+) ions remains limited, which frames the central problem of this study. In addressing this issue, the method employed involves synthesizing carrageenan hydrogel through alkaline extraction of Eucheuma cottonii and evaluating its adsorption capacity under controlled experimental conditions. The hydrogel was characterized and tested at pH 6–7, with a contact time of 90 minutes, an initial concentration of 200 mg/L, and an adsorbent mass of 6 g, followed by kinetic and isotherm modeling to analyze adsorption behavior. Based on the Findings, ionic exchange interactions between sulfate ester groups of K-carrageenan and metal cations significantly enhance adsorption performance, with the adsorption process following a pseudo-second-order kinetic model and the Freundlich isotherm providing the best fit R2 > 0.90, indicating heterogeneous multilayer adsorption. In the Conclusion, the chemically modified carrageenan hydrogel demonstrates effective adsorption of copper and cadmium ions and presents strong potential as an eco-friendly and efficient biomaterial for heavy metal remediation.
