Teaching materials are an important component in the learning process that play a role in improving the abilities and skills of students. The contextual approach is one of the learning strategies that emphasizes the connection between lesson materials and students’ real-life experiences, thereby creating more meaningful learning experiences. However, the instructional materials currently used by chemistry teachers are still dominated by printed textbooks and conventional worksheets that have not yet integrated the contextual approach and digital technology. Therefore, this study aims to develop a contextual-based E-LKPD on reaction rate material to improve students’ science literacy. The method used Research and Development (R&D) with the ADDIE model, which consists of five stages: Analyze, Design, Development, Implementation, and Evaluation. The validation results from experts indicate that the E-LKPD achieved a score of 87.5% for high validity. Practicality tests with teachers and students yielded scores of 82.5% and 88.33%, respectively into the highly practical category. Meanwhile, the effectiveness test through pretest and posttest yielded an N-Gain score of 60.82%, falling into the moderate to high category, and was deemed effective. Thus, the contextual E-LKPD on reaction rate material is suitable for use in learning to support the improvement of students’ science literacy.
