This study aimed to develop and determine the usability of Geometrical Optics Learning Module (GOLeM) towards Physics Matriculation students. The GOLeM was developed using ADDIE (Analyze, Design, Develop, Implement, Evaluate) model and this module had been validated by seven experts. This research used a questionnaire to evaluate the usability of the developed module. The research sample consisted of 186 students that was selected through cluster random sampling from an accessible population of 359 Physics Module II students in Perak Matriculation College. The research instrument was usability questionnaire that was used to measure the students’ perceptions towards the usability of the module. The questionnaire was adapted based on the Technology Acceptance Model (TAM). The data were analysed using descriptive and inferential statistics including frequency, mean, standard deviation and independent t-test.
