Abstract

The purpose of this research is to produce development products of virtual laboratory media with a STEM approach and equipped with appropriate feedback to be applied in learning and the opportunity to improve critical thinking skills on acid-base concepts. This research consisted of (1) analysis (needs analysis and front-end analysis), (2) design, and (3) development. The research instrument used consisted of interview questionnaires, media feasibility validation sheets, material feasibility, concept validity, and readability test questionnaires. Media and subject matter experts who are involved are a teacher, a lecturer, and 33 students as respondents to test readability. While The results showed that the product virtual labs application, user guide, and a feedback book has a percentage of 89 % for feasibility media, 85% for the feasibility of the material, and 100% for the truth of a concept that can be in the category is very feasible. The media readability test by students obtained a percentage result of 81 % with a very good category. Therefore, this virtual laboratory is very feasible to be applied in learning activities and has the opportunity to improve students’ critical thinking skills on the acid-base concept. Recommended future research can apply this product in classroom learning.
