Abstract

The aim of this research is to analyzing students' psychomotor abilities in daily life -based practicums on reaction rate material. This research was carried out in the 2022/2023 academic year at Madrasah Aliyah Negeri 1 Kampar with the material Reaction Rate. The method used in this research is quantitative descriptive. The instruments used in this research were performance assessment sheets to determine students' psychomotor abilities and interviews to strengthen the data obtained. The results of data analysis show that the average psychomotor ability of students is 79.19. The highest average score obtained was in the naturalization domain with the very good category and the psychomotor ability with the lowest average score obtained was in the precision domain with the good category. The psychomotor indicator with the highest average score is assembling experimental equipment in the very good category, and the psychomotor indicator with the lowest average score is the indicator for splitting and smoothing solid substances in the good category. The psychomotor abilities of the students are mostly in the good category, which is 52% with the highest rating scale score being scale 4 with a good category, which is 59%. Daily life -based chemistry practical learning can make it easier for students to carry out practical work.

Abstract

This study explores how integrating local cultural practices into chemistry education through ethnochemistry can provide a practical and relevant solution to these challenges. Conducted in Oeseli Village, a seven-day ethnographic study employed observations, interviews, and documentation to identify culturally significant products, such as Rote sugar, sopi (a traditional alcoholic beverage), and fried milk. These products were found to align with key chemistry concepts, including organic chemistry, fermentation, and particle interactions. By embedding these cultural assets into the chemistry curriculum, educators can enhance student engagement, contextualize learning, and overcome barriers imposed by the lack of traditional laboratory resources. The findings highlight the potential for using local traditions to foster a deeper understanding of chemistry while promoting science education that is both accessible and culturally relevant in remote regions like Rote Ndao. This approach encourages the development of a sustainable, localized educational model that can be adapted to other marginalized communities facing similar educational constraints.

Abstract

This study aims to examine the application of lesson study design on chemistry material in improving critical thinking skills of students in class XI-2 SMA Negeri 2 Semarang. The research was conducted for three meetings involving the implementation of Project-Based Learning (PjBL) learning model with STEM (Science, Technology, Engineering, Mathematics) approach. The lesson study stages included planning, implementation, and reflection focusing on reaction rate material, involving students in collaborative activities such as designing and testing simple tools. The results showed that the application of the STEM-based PjBL model significantly improved students' critical thinking skills. This improvement can be seen from students' ability to identify, analyse, and solve problems based on relevant theories. The learning activities implemented, such as group discussions and windows shopping activities, also play an important role in improving interaction and collaboration between students. The implementation of STEM in PjBL not only deepens students‘ understanding of chemical concepts, but also increases students’ interest and active participation in the learning process. This study concludes that the application of STEM-based PjBL learning model, collaborated with lesson study, is able to improve critical thinking skills and the quality of chemistry learning on reaction rate material.

Abstract

The lack of variety in instructional media can be a starting point for the difficulty in creating an effective and enjoyable learning environment, particularly in chemistry subjects. The concepts in chemical bonding are abstract, making them difficult to apply contextually. Based on these issues, the researchers developed CHEMILARD (Chemistry Flashcard) media using augmented reality. This research employed the D&D (Design and Development) model. The subjects of this study were 6 expert validators in media and content, as well as 25 respondents. The data analysis techniques included Aiken’s analysis and percentage models. The study concluded that the validation of CHEMILARD media, developed across all assessment aspects, indicated that the product is feasible for trial implementation with a score of V=0.90 from media experts and V=0.91 from content experts. The respondents' test results showed an ideal media percentage of 90.3% and an overall media quality rating of 76.72, which is categorized as Very Good. This indicates that the augmented reality-based CHEMILARD media can significantly enhance the learning experience by making abstract chemical bonding concepts more tangible and easier to understand for students.

Abstract

In improving the quality of learning, it is necessary to develop a learning design that can facilitate the characteristics of students. The didactical design can facilitate the characteristics of students through sharing and jumping tasks. Sharing task is used to facilitate slow learner while jumping task is used to facilitate fast learner. Jumping task is not only beneficial for students with high academic ability, but also provides benefits for students with low academic ability. The purpose of this study is to develop the didactical design based on sharing and jumping tasks to enhance learning quality on the topic of reaction rate low. The research method used is didactical design research (DDR). Didactical design consisted of three steps i.e. (a) analysis of didactical situation before learning (prospective), (b) analysis of didactical situation during learning (metapedadidactical), and (c) analysis of didactical situation after learning (retrospective). The data was collected by test, observation, interview, documentation and recording (audio and video). The result showed that the didactical design on the topic of reaction was valid

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.

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.
