Development of Online Problem-Based Learning Module for Impulsive Force Subtopic of Physics Form Four

In this study, we developed an online problem-based learning (PBL) module for the Impulsive Force subtopic of Physics Form Four and studied its perceived usability among Physics trainee teachers. The research design of this study is developmental research and a quantitative study using a survey approach. The module was developed according to five phases of the ADDIE instructional design model; analysis, design, development, implementation and evaluation. The module had a high agreement percentage among three appointed experts for face validity (98%) and content validity (95%). The sample of this study were selected among Physics trainee teachers of Universiti Pendidikan Sultan Idris using a simple random sampling technique. The perceived usability level of the developed module among trainee teachers were determined using a usability questionnaire. The collected data were analyzed by calculating the frequency, mean (M) and standard deviation (SD) values. The findings indicated that trainee teachers has a high perceived usability level for each aspect; usefulness (M = 3.76; SD = 0.32), ease of use (M = 3.72; SD = 0.35) and satisfaction (M = 3.79; SD = 0.30) for the developed module. Overall, the module also has a high perceived usability level among trainee teachers (M = 3.76; SD = 0.32). Thus, the developed online PBL module is suitable as a learning aid for the Impulsive Force subtopic for Physics Form Four.
