Abstract

Learning resources that are often used in learning only use limited print media and do not attract students' motivation, scientific attitude, and learning independence. For this reason, the right learning media is needed to improve it through electronic student worksheet media. This study aims to produce electronic student worksheet based on Problem-based Learning (PBL) on electrochemical material that is suitable for use in learning chemistry, determine characteristics, analyze practicality based on the assessment of high school chemistry teachers, and analyze responses and readability based on the assessment of high school students. This research used the Research and Development (R&D) research method with the 4D development model. The electronic student worksheet contains 4 learning activities and is equipped with pictures, audio, video, and declared feasible by chemistry learning experts. The results of the practicality test assessment by chemistry teachers obtained an average score of 94.4 out of a maximum score of 105 and an ideal percentage of 89.90% which is included in the ‘Very Good’ category. The results of the response test assessment and readability by students obtained an average score of 52.2 from a maximum score of 60, an ideal percentage of 87.50% which is included in the ‘Very Good’ category

Abstract

This study investigates the effect of an ethnochemistry-based flipped problem-based learning (FPBL) model on students’ chemical literacy in buffer solution material. The research employed a quasi-experimental design with pre-test and post-test control groups. Data were collected through chemical literacy tests and analyzed using MANOVA at a 5% significance level. The results revealed a significant difference in chemical literacy between students who learned through the ethnochemistry-based FPBL model and those instructed using a conventional scientific approach. The model contributed 23.5% to the improvement in students’ chemical literacy, indicating a substantial effect. Furthermore, students exposed to the ethnochemistry-based FPBL model demonstrated enhanced ability to integrate chemical concepts with problem-solving and apply knowledge in practical scenarios. These findings highlight the effectiveness of incorporating ethnochemistry elements into flipped problem-based learning, providing a structured and culturally relevant approach that promotes deeper understanding of chemistry concepts. This study offers evidence that the ethnochemistry-based FPBL model can serve as an effective pedagogical strategy to enhance chemical literacy, suggesting its potential for broader application in chemistry education.
