Development of Chemistry Practical Guide: Integration of PjBL with Augmented Reality Technology in Electrolysis Practical

This study aims to develop a Chemistry Practical Guide integrating Project-Based Learning (PjBL) and Augmented Reality (AR) for the electrolysis topic to enhance students’ conceptual understanding and engagement in chemistry practicum. The research employed a Research and Development (R&D) method using the 4D model (Define, Design, Develop, and Disseminate), conducted up to the Develop stage. The product was validated by three material experts and two media experts, and tested on teachers and students for practicality. The results showed that the guide achieved very high validity scores from material experts (93.8%) and media experts (93.4%). Teacher (90.6%) and student (90.6%) responses also indicated excellent practicality and usability. The integration of PjBL promoted inquiry, collaboration, and critical thinking, while AR technology enhanced visualization of abstract electrochemical processes. The developed guide bridges theoretical understanding and experimental application, serving as an innovative digital-based learning resource for 21st-century chemistry education.
