Development of Instagram-Based Learning Media to Increase Students Learning Interest in Acid-Base Materials

This study aims to determine the feasibility of Instagram-based chemistry learning media and the results of increasing student interest in learning acid-base material in everyday life with a multi-representation approach. The method used in this study is the ADDIE research and development model (Analysis, Design, Development, Implementation, and Evaluation). The research population is SMAN 3 Sidoarjo students, with the sample used being 89 students who carry out learning using Instagram in acid-base material in everyday life. Quantitative data was obtained from material and media validation results, as well as an analysis of student interest in learning before and after using the media. Qualitative data were obtained by analyzing descriptive questions of student learning interest in chemistry questionnaires. The results of the research on developing Instagram-based chemistry learning media on acid-base materials in everyday life with a multi-representation approach were obtained: 1) the feasibility of learning media developed based on the results of the assessment of materials and media by expert validators was included in the very feasible category; 2) the increase in students' learning motivation is in the medium category with a standard gain value of 0.40.
