Development of Virtual Science Laboratory (VSL) on Linear Motion Concept

Abstract

Laboratory activities play a very important role in supporting science learning activity which allows students to gain practical skills through experimentation and provides opportunities to have a deeper understanding of the content or concepts being studied. Especially during the current covid-19 pandemic, laboratory activities are directly limited or even eliminated, therefore there needs to be a solution for implementing substitute laboratory activities so that student competencies, especially practical skills through experimental activities, are still mastered. The most likely opportunity is through virtual laboratory activities. This study aims to develop a Virtual Science Laboratory (VSL) in the form of a computer application designed to improve the learning approach by introducing a safe and interactive lab environment for students. The design of this research is Research and Development (R & D) with the ADDIE (Analysis, Design, Develop, Implementation and Evaluation) method. The Virtual Science Laboratory (VSL) learning media product has produced the concept of linear motion using a Virtual Ticker Timer. The feasibility of the VSL for linear motion concept was analyzed based on the average percentage score of material expert validation 83.0%, media/ technology expert validation 84.0%, teacher validation 87.5% and it can be concluded that the validation reached the very feasible criteria.
