Abstract

Learning about ethnoscience can help students better understand chemistry because it connects to their daily experiences. However, students often struggle with redox and electrochemical concepts due to a lack of appropriate learning materials and difficulty grasping these ideas. This research aims to achieve the following objectives: (1) develop ethnoscience-based student worksheets on redox reactions, Volta cells, and corrosion using Liveworksheets, following the 4D development model modified to 3D; (2) create ethnoscience-based student worksheets on these topics that are valid, effective, and practical. The research employed validation sheets and questionnaires as instruments, with a sample of six students from the 12th grade. Data was analyzed descriptively. The results indicate that (1) the modified 4D development model was suitable for creating the student worksheets due to its systematic stages and adaptability to researchers' needs; (2) both the media and material showed high validity percentages, averaging 88% and 89%, respectively. The worksheets were considered quite effective, with an average percentage of 66%, and practical, with an average percentage of 78%. Overall, the developed product can be effectively used to teach redox reactions, voltaic cells, and corrosion in chemistry using Liveworksheets.Keywords: Corrosion; Ethnoscience; Redox reaction; Students’ worksheets; Voltaic cell

Abstract

Conventional media, like textbooks, lack interaction explaining chemical bonding, hindering dynamic learning. They're static and unable to visualize bonding effectively. Moreover, unengaging teaching methods cause student disinterest, hindering learning, particularly in complex subjects like chemical bonding. To address this issue, developing augmented reality-based chemical bonding modules is a potential solution to help students learn about chemical bonding. This study aims to accomplish the following objectives: (1) Develop a chemical bonding module based on augmented reality using the Assemblr EDU, following the ADDIE development model. (2) Determine the feasibility of the augmented reality-based chemical bonding module. The research methodology employed in this study is Research and Development (R&D), utilizing the ADDIE development model. The study's findings reveal the following: (1) The module was developed using the ADDIE development model with the Assemblr EDU. (2) The augmented reality-based chemical bonding module is highly valid, achieving a material validity score of 89.33% and a media validity score of 93.5%. It is also convenient, earning an average practicality rating of 88.14% with an "excellent" response from users. Additionally, the module is effective, as evidenced by a student evaluation score averaging 70, which falls within the high criteria range. The augmented reality-based module is a valuable tool for enhancing the understanding of chemical bonding during learning.
