Food Fermentation as a Virtual Laboratory Learning Media to Empower Student’s Science Process Skills

Abstract

The purposes of this research are to produce a discovery learning-based virtual laboratory learning media, to assay the feasibility of the media, and to test students' science process skills before and after the implementation of developed media.  The research method used is a Research and Development (R&D) with a 4D (Four-D Model) which was modified into 3D (Define, Design, and Develop). The validation stage was carried out by a media expert, content expert, and learning expert. The instruments used include questionnaires for the analysis of student needs, interview questionnaires, validator instruments, student responses, teacher responses, and pretest-posttest. The data collection technique was carried out by distributing student and teacher response questionnaires after learning. Science process skills are measured using a pretest-posttest. The virtual-laboratory learning media can be operated on android and personal computers (PC). The validation results showed that the multimedia was very feasible with a percentage of 92.7%, meanwhile, the material, and evaluation validation were considered feasible, with a percentage of 85.1% and 83.02% respectively. There were differences in students' science process skills before and after the implementation of discovery learning-based virtual laboratory learning media shown by the results of the paired t-test, namely the Sig value (2-tailed) 0.000<0.05
