Abstract


This study aims to assess the validity and practicality of computational chemistry practicum modules for high school students, focusing on molecular geometry and independent learning. The research used a Research and Development (R&D) approach with the 4D model (define, design, develop, and disseminate). A limited trial was conducted with 23 students selected through cluster random sampling. The module development research results show that the validity assessed using Aiken's V index by two validators yielded a value of 0.64, indicating its validity and suitability for high school students. Furthermore, the practicality of the module was evaluated using a student response questionnaire, which yielded an average score of 84%, indicating its high practicality. Consequently, the module is considered valid and highly practical as a practicum learning resource for high school students.
