Development of Android-Based Mobile learning media on Atomic Structure and Periodic Table

This study aims to develop an Android-Based Mobile Learning Media on Atomic Structure and Periodic Table. The development of mobile learning media adapted the research and development stages by Borg & Gall which was reduced to three stages: needs assessment, media development, and media testing. Mobile learning media that has been developed is an Android-based application (.apk) named ATOMOB, with size less than 45 MB compatible on Android devices with variety of screen resolution sizes. It was reviewed by expert of chemistry, expert of multimedia, chemistry teachers, and students. The quality of this media was determined based on the aspect of subject matter, language, operating process, audio and visual display. The assessment data are collected from 10 experts, 5 chemistry teachers and 100 senior high school students by using Likert questionnaire. Overall interpretation of assessments by experts, students, and teachers resulted in very good criteria on each assessment indicator. This mobile learning media can motivate students to learn more about chemistry because students said this media is interesting, attractive, and make learning more meaningful. Therefore, mobile learning media that has been developed is feasible to be used as learning media and suitable with students' needs.
