Development of an Interactive Virtual Laboratory for Modern Physics Courses Based on Lectora Inspire

Abstract

This study aimed to develop a modern physics virtual laboratory based on Lectora Inspire and to determine the feasibility of the developed media as well as students’ responses to its implementation in modern physics learning. The developed product consists of four experimental modules, namely the Millikan oil drop experiment, blackbody radiation, hydrogen atomic energy levels, and the photoelectric effect. This research employed a Research and Development (R&D) approach using the ADDIE development model, which comprises the stages of Analysis, Design, Development, Implementation, and Evaluation. The research instruments included expert validation questionnaires and user response questionnaires. Expert validation was conducted to assess the aspects of functionality and usefulness, visual and audio quality, typography, and language. Meanwhile, user responses were collected to evaluate the ease of use, media attractiveness, and learning activities facilitated by the virtual laboratory. The results indicated that the developed virtual laboratory was categorized as feasible based on expert validation assessments. The aspects of functionality and usefulness, typography, and language received high ratings, indicating that the media is suitable for use as a learning resource in modern physics courses. Furthermore, student responses revealed positive perceptions of the virtual laboratory, with the majority of evaluations falling within the “Good” and “Very Good” categories across all assessment aspects. Students reported that the virtual laboratory was easy to use, engaging, and effective in facilitating their understanding of abstract modern physics concepts through interactive simulations. Therefore, the Lectora Inspire-based modern physics virtual laboratory can serve as an alternative learning medium to support modern physics practical activities in higher education institutions.
