Development of Online Learning Tools Based on Computer Assisted Instruction Material for Newton’s Law of Gravity

Abstract This study aims to develop an online learning tool based on Computer Assisted Instruction. The research method used is Research and Development using the ADDIE model which consists of five stages, namely: Analysis, Design, Development. Implementation, Evaluation. was developed e-learning media, namely webbased student’s worksheet. Instruction has been tested a limited basis for tenth grade students public high school. data collected by distributing questionnaires grid made google form, starting from stage analyzing teacher-student needs, validating 3 experts, testing teachers documentation. validation results were obtained 82.875% media 80% material experts 82.42% experts. Based analysis that collected, it can be concluded tools Newton’s Law Gravity are very good feasible develop.
