Chemistry learning, particularly in the context of reaction rates, is often considered complex and abstract, necessitating innovative learning media that can effectively link concepts to real-world contexts. One solution is the development of electronic-based teaching materials in the form of E-Student Worksheet (Electronic Student Worksheets) that utilize environmental issues as a contextual approach. This study aims to develop an Environmentally Based Chemistry Practicum E-Student Worksheet on reaction rates that is valid, practical, and suitable for use as a learning medium. The research method employs the ADDIE (Analyze, Design, Develop, Implement, and Evaluate) development model. The research respondents included two media experts, two material experts from Chemistry Education lecturers, and 24 high school teachers who assessed the product quality. The results showed that the assessment by the media experts and material experts obtained an average score of 82%, which is categorized as very good. In addition, a limited trial with high school teachers yielded an average score of 87%, indicating that the E-Student Worksheet received a positive response and was well-received as a learning medium. Based on these findings, it can be concluded that the Environmentally Based Chemistry Practical E-Student Worksheet utilizes the Flipbook Builder application in a manner that meets the needs of students, is suitable for learning, and has the potential to enhance the understanding of chemical concepts through an environmentally based contextual approach.
