Development and Validation of a Computer Simulation-Based Laboratory Manual for Gas Laws

This study developed and validated a laboratory manual for teaching gas laws using computer-aided simulations to address challenges in chemistry education. Utilizing a descriptive educational and research model alongside the ADDIE framework, the manual was evaluated by expert validators and tested with Grade 11 STEM students and teachers. The validation results by the experts were evident in all criteria, including pedagogical approach, content relevance, technology integration, assessment strategies, and teacher support and professional development. The manual effectively promotes student-centered learning, aligns with curriculum standards, and enhances engagement and comprehension through technology integration, providing a valuable resource for teachers and improving student outcomes.
