Abstract

Chemistry learning, particularly on chemical bonding material, is often confronted with abstract and mathematical concepts that lead to low conceptual understanding and learning interest among vocational high school (SMK) students. Conventional one-way teaching methods tend to fail in connecting the macroscopic, submicroscopic, and symbolic levels of representation, causing fragmented understanding. This study aims to develop and evaluate the feasibility of the 3DChem Android application as a visualization medium for abstract concepts in chemical bonding material based on a Multiple Representation approach. The research employed Research and Development (R&D) methodology with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation) and a qualitative-descriptive approach involving validation sheets and student response questionnaires. The subjects were one media expert, one material expert, and 20 students of SMK Madani Manado. The results showed that the 3DChem application received a feasibility percentage of 96.74% from the media expert (highly feasible), 93.33% from the material expert (highly feasible), and 88.44% positive student responses (highly positive). It is concluded that the 3DChem application is highly feasible as a visualization medium for abstract concepts of chemical bonding for SMK students
