The development of an inquiry-based catalase enzyme virtual laboratory for improving students' science process skills

Abstract

The inadequate laboratory facilities, limited time, and the Covid-19 pandemic had become obstacles in carrying out practicum activities. In overcoming this problem, practicum activities became virtual. This research aimed to develop an inquiry-based catalase enzyme virtual laboratory for improving students’ science process skills. This research used the educational research and development design of the ADDIE model (Analyze, Design, Develop, Implement, and Evaluation). The research sample was 80 students at one of the senior high schools in Riau. The research instruments used were validation sheets, virtual laboratory readability questionnaires, and the science process skills test. The results showed that the feasibility level of the virtual laboratory developed was in the very feasible category namely 94.77% (media aspect) and the feasible category namely 84.52% (material aspect). The virtual laboratory readability result showed an average value of 83.25% (the very good category). The N-gain value of students' science process skills was 0.77 (the high category). The virtual laboratory of the catalase enzyme developed was feasible for use and can improve students’ science process skills in senior high school.
