摘要:AbstractThe study was aimed at designing and developing a web-based teaching courseware, Webquest, for secondary school Physics module by employing the Isman Instructional Design Model and to test the effectiveness of the module. The paper draws attention to the design principles of the Isman Instructional Design Model. The prototype module was tested among a teacher and 4 students. The findings from interviews with the teacher and students show a positive response in attracting the students’ interests toward the topic. The module was then implemented with 30 participants. In the evaluation phase, students’ achievement score instrument was used to collect data for this study. The pre-posttest design conducted suggested that the module is effective.The findings from this study suggest that the Isman Instructional Design Model which pays attention to instruction from the learner's perspective than from content perspective is suitable in designing and developing Webquest for Physics module in the secondary educational setting in Malaysia. The findings of this study are expected to provide insights into promoting teaching and learning of Physics based on Webquest.
