Development of Android-Based Mobile Learning (M-Learning) on Voltaic Cell Sub Materials to Increase Learning Effectiveness in Pandemic Covid-19 Era

This study was conducted to know the worthiness of learning media mobile (M-Learning) is increasing students' effectiveness. Research and Development (R&D) has adapted method used. The research involving 26 students three validators. validator consists 1 lecturer as a expert lecturer, one material expert, chemistry teacher. Based on results, results obtained validity 93%, effectiveness in terms student scores much 41.9%. So that android-based M-Learning product developed can be said feasible implemented voltaic cell sub materials.
