A Usability and Motivation Analysis of Laboratory Manuals for Empowering Non-Science Students in Chemistry

Well-designed laboratory manuals enhance usability, motivate learning and improve experimental skills. This study explores the relationship between usability and motivation in chemistry education for pre-university non-science students, specifically through the effectiveness of a laboratory manual. An online survey was conducted using a quantitative approach with 76 students from four branches of University Technology MARA in Malaysia. Statistical analysis indicated a significant positive correlation between usability and motivation, emphasizing the role of well-crafted laboratory manuals in developing practical skills and generating interest in chemistry. Key design elements such as clarity, ease of understanding, and relevance were assessed with the ADDIE model, while motivation factors were measured through Keller’s ARCS model. The findings highlight the value of customized instructional materials in supporting education for sustainable development (ESD), especially for non-science students. This study offers valuable insights for improving STEM education, promoting sustainability, and advancing interdisciplinary learning in challenging fields like chemistry.
