Abstract

The research aims to determine the effect of the ethnoscience approach through the problem-based learning model on the chemical literacy skills of Grade XI students in the reaction rate material at SMA Negeri 7 Gorontalo. The research employs a quasi experimental method with a nonequivalent control group design. The sample consisted of Grade XI IPA ( Natural Science) students from SMA Negeri 7 Gorontalo. The instrument used in this research was an essay test. Data processing and analysis were conducted using Microsoft Office Excel and SPSS version 16. The hypothesis test results on students’ post-test data using the Mann-Whitney test at a significance level of α = 0.05 showed that the Asymp. Sig. (2-tailed) value was less than 0.05 (0,002 < 0,05). Therefore, H1 was confirmed, and H0 was rejected. The N- Gain test results also indicated that the ethnoscience approach through the problem-based learning model was moderately effective in improving students’ chemical literacy skills in reaction rate material, with the experimental class achieving an N-Gain score percentage of 57.13% (moderately effective category), while the control class achieved a percentage of 31.42% (ineffective category). In conclusion, the ethnoscience approach through the problem-based learning model significantly affects students’ chemical literacy skills in reaction rate material.

Abstract

This research aimed to examine the effect of the CERDAS learning model on student learning outcomes. The research employed a quasi-experimental method with a non-equivalent prest-posttest control group design. The sample consisted of students from class X Merdeka 3, serving as the experimental group, and class X Merdeka 1 as the control group. Both from SMA Negeri 7 Prasetya Gorontalo. These classes were selected using purposive sampling. The research instrument was an objective test. The results revealed a significant difference in the average scores between the experimental and control classes. Specifically, the average student learning outcome in the experimental group was 79,77, while in the control group, it was 67,27. Hypothesis testing using the t-tes yielded tcount value > ttable, indicated the tcount (2,99) was greater than the ttable value (2,01), which led to the rejection of H0 and confirmation of H1, Confirming that the CERDAS learning model had a significant effect on student learning outcomes. Additionally, the N-Gain test showed a moderate effect (0,68), indicating that the CERDAS learning model is fairly effective in improving student learning outcomes.

Abstract

Mastery of the ChemDraw application is an important skill for chemistry students in supporting academic activities, especially in drawing chemical structures and reactions. However, not all students have the opportunity to learn this application formally. This service activity aims to provide training in the use of ChemDraw online to chemistry students by utilizing digital media. The implementation method includes an interactive workshop approach through Zoom, Google Meet, and social media as a means of disseminating information and documentation. The results showed that the training was effective in improving participants' understanding and skills in using ChemDraw. Digital media proved to be an efficient and flexible tool for training computer-based applications. This activity supports the improvement of students' digital literacy and 21st century skills.

Abstract

Understanding chemical equilibrium concepts poses significant challenges for high school students due to the topic’s abstract and complex nature. This literature review identifies key factors contributing to these difficulties, including widespread misconceptions, cognitive and pedagogical barriers, and environmental influences such as family support and learning resources. The review highlights the importance of constructivist and cognitive learning theories in designing effective instructional strategies that actively engage students and facilitate deeper conceptual understanding. Furthermore, the integration of educational technologies—such as interactive simulations and virtual laboratories—provides enriched learning experiences that help overcome conceptual misunderstandings. An integrated approach combining innovative teaching methods and technology use is recommended to enhance students’ comprehension of chemical equilibrium. Future research should focus on practical applications of these models and evaluate their effectiveness across diverse educational settings.

Abstract

This study is a literature review aimed at examining the effectiveness of the guided inquiry model based on STEM in enhancing students’ critical thinking skills. The guided inquiry model provides a structured framework for students to explore problems under teacher guidance, while the STEM (Science, Technology, Engineering, and Mathematics) approach promotes interdisciplinary, contextual, and practical learning. Through an analysis of various relevant articles and scholarly journals, the findings indicate that the implementation of the guided inquiry model integrated with STEM consistently improves students' critical thinking abilities, particularly in areas such as analysis, evaluation, and reasoning. The study also highlights the crucial role of teachers as active facilitators in the learning process and the need for adequate resources to effectively apply this approach. The results of this review are expected to serve as a reference for educators and researchers in developing innovative and 21st-century-oriented learning strategies.

Abstract

This study aims to review various methods and applications of the ethnochemistry approach in chemistry education through a literature review. Ethnochemistry connects chemical concepts with local wisdom and culture, providing deeper contextualization for students. The literature review was conducted by collecting data from various articles relevant to this topic, published between 2018 and 2024. The review results indicate that integrating ethnochemistry into chemistry learning can enhance students' understanding of chemical concepts, scientific skills, creativity, and engagement. This approach also helps preserve traditional chemical knowledge that may otherwise be lost. This study concludes that ethnochemistry is a significant innovation that can improve the quality of chemistry education in a more meaningful and relevant way for students, while also strengthening their cultural identity.
