Abstract

During the COVID-19 pandemic, learning methods have changed significantly. Practicum with conventional methods that are not possible can be done virtually using a virtual laboratory. STEM (Science, Technology, Engineering, Mathematics) is one of the bases that can be used in experiments in the laboratory. STEM meets the criteria for 21st-century learning which emphasizes contextual problem-solving-based learning to understand learners to abstract theories. Stem-based developed virtual labs. This paper focuses on two stages, namely the development and validation of a virtual laboratory. The method used in this development is the DBR (Design-Based Research) method. Two DBR cycles measure the readability, comprehensibility, and feasibility of a Virtual STEM laboratory.

Keywords: Laboratory STEM Virtual, Development, Validation, Design-based Research.
