This study aims to evaluate the usability and effectiveness of the Healthy Lifestyle Module (MoGHS) as a teaching aid in co-curricular courses of the matriculation program in Malaysia. This study uses a one-shot study evaluation method involving 18 lecturers and 127 students as respondents, where the usability of the module is assessed based on three main constructs: usefulness, satisfaction, and ease of use. The usability questionnaire adapted from the USE model was tested for content validity and reliability through excellent Cronbach's Alpha values (α > 0.9). The results of the study showed that lecturers gave high scores on the usability of MoGHS, with an overall mean score of usefulness of 4.90 (SD = 0.266), satisfaction of 4.94 (SD = 0.207), and ease of use of 4.92 (SD = 0.243). Further analysis of the three learning domains – cognitive, affective, and psychomotor – found positive improvements in the cognitive and affective domains, while the psychomotor domain required further improvement. MoGHS can serve as a tool to show educators that the idea of a healthy lifestyle can be made clear, and it serves to meet educators' needs to conduct quality and efficient teaching. MoGHS is a practical educational tool that can be used as a contribution to the holistic education of Malaysian National Education Philosophy. The psychomotor component requires improvement so that the effectiveness of the next generation of this module can be strengthened.
