Abstract

This study aimed to analyze the implementation of project-based worksheets utilizing red dragon fruit peel waste (Hylocereus polyrhizus) to develop students’ science process skills (SPS). The research employed a pre-experimental method with a one-shot case study design, conducted at a vocational high school in Cimahi City, involving 31 senior high school students from Class XI Industrial Chemistry-C. The research instruments consisted of student activity observation sheets, project-based worksheets, and SPS performance sheets. The results showed an average student activity score of 95%, a cognitive SPS score of 90%, and a psychomotor SPS score of 96%, all categorized as “excellent.” Hence, the project-based worksheet on producing edible straws from red dragon fruit peel waste was proven to be highly feasible and effective in developing students’ SPS.

Abstract

The present study by investigating an alternative approach integrating natural materials to create more contextual and meaningful learning experiences. A quasi-experimental design was employed, with the experimental group engaging in hands-on laboratory projects using natural indicators such as purple cabbage extract, eggshell waste, and vinegar, while the control group received conventional instruction. Independent t-test analysis revealed a significant difference between the groups, with the experimental group outperforming the control group in post-test assessments of scientific literacy and critical thinking. These findings indicate that incorporating environmentally friendly, context-based materials into chemistry education could effectively enhance essential skills. Moreover, the project-based approach encouraged students to apply scientific concepts, think critically, and relate their learning directly to everyday life.

Abstract

The purpose of this study was to describe the mental model of students on the acid-base material class XI phase F. The type of research used is descriptive research with a quantitative approach. The research population consisted of students in class XI Phase F, and the research sample comprised 31 students from XI F9 at SMAN 2 Payakumbuh, using a purposive sampling technique. The data collection technique was conducted in two stages: the test stage and the interview stage. This test stage utilises a four-tier diagnostic test instrument, employing three levels of chemical representation. Then, the interview stage is conducted to gather data and confirm the results of the diagnostic tests that have been performed. The findings of this study detected that students have varied mental models. There are 41.1% have a mental model of synthesis-partial understanding B; 19.6% synthesis-partial understanding A; 15% initial model; 12.5% scientific model, and 11.8% synthesis-misconception. This is supported by the presentation agreement of the interview result with the diagnostic test.

Abstract

This research aims to develop an engaging and effective learning tool that motivates students to learn more effectively and understand scientific concepts more deeply. This article introduces FUN_COLLOID, an interactive multimedia learning platform designed to enhance students' understanding of colloids, a crucial topic in chemistry. The methods used in this study include the development of interactive multimedia content, such as educational videos, virtual laboratories, and quizzes, as well as the evaluation of their impact on students' interest and understanding. The results showed that the use of FUN_COLLOID significantly improved students' understanding of colloid concepts, as well as increased their involvement in the learning process. The conclusion of this study emphasizes the importance of innovation in learning media to improve the quality of education in Indonesia, and provides recommendations for the further development of this platform so that it can be used in various other learning contexts.

Abstract

This research aimed to describe the validity or feasibility value of developing a game-based augmented reality learning application to introduce chemical laboratory equipment. The application developed was AR-LAB (Augmented Reality Laboratory), combining augmented reality technology with quizzes. This research employed development research using Richey and Klein's theory, which contains three steps: planning, production, and evaluation. The results show that the product's validity by material and media experts was 91.67% and 91.67%, respectively, in the very good category. The teacher assessment provided an average score of 112.4 from the ideal maximum score of 120, with an ideal level reaching 93.60% in the very good category. Meanwhile, testing by ten students obtained the maximum score in the very good category. The successfully developed media has the advantage of introducing laboratory equipment in three dimensions that are affordable and easy for students to learn about chemical laboratory equipment.

Abstract

Low levels of critical thinking skills among students on the topic of chemical equilibrium pose a significant challenge in chemistry education. This topic demands strong analytical, evaluative, and problem-solving abilities. This study aimed to investigate the effectiveness of the Think-Pair-Square (TPSq) learning model in enhancing students’ critical thinking skills. A pre-experimental one-group pretest–posttest design was employed, involving 59 students from two classes selected through cluster random sampling. Data were collected using a critical thinking skills test administered before and after the intervention, and analyzed using N-Gain and effect size. The results indicated a significant improvement in students’ critical thinking skills, with an average N-Gain of 0.48 (moderate category) and an effect size of 2.75 (very high category). These findings suggest that TPSq is an effective collaborative learning strategy for developing critical thinking skills in chemical equilibrium and can serve as an alternative instructional method that promotes student interaction and discussion.
