Development of Mobile Learning with a Scientific Approach on Thermochemistry Material in Senior High School

Abstract

Thermochemistry provides a foundation for understanding subsequent chemistry concepts such as equlibrium. However, its abstract concepts and complex calculations often lead to student difficulties and misconceptions, highlighting the need for interactive learning media to facilitate better understanding. This study aims to develop mobile learning media with a scientific approach on thermochemistry material. The research method used in this study is the Research and Development (R&D) method from Borg & Gall, involving 50 Grade 11 senior school students. The application was developed using Adobe Animate CC 2022. Data were collected through questionnaires, including analysis questionnaire for students and teacher, expert feasibility assesment questionnaires and student evaluation questionnaires. Data were analyzed using quantitative descriptive analysis using a Likert scale, descriptive quality criteria with a rating scale, and Hyot’s reliability test. The results of the study indicate that the assessment by media experts and subject matter and language experts was 83.7% (r=0.824) and 85.2% (r=0.961), respectively with a very good interpretation; and students evaluations on the small and large scales averaged 85.7% and 90.4%, respectively all interpreted as a very good. This study was limited to evaluating the feasibility. Futher research is recomended to involve a larger samples and integrate’ misconceptions identification strategies.
