Development of android-based gymnastics learning media to improve the ability to roll ahead straddle students in gymnastic learning

Abstract
This research aims to develop a valid, practical, and effective gymnastics learning medium to improve the ability to roll ahead to students on gymnastics learning. The development process of this model refers to the Plomp development model. The subject of the study is a student of the Department of Sports Education, Faculty of Sports Sciences. Data collection techniques use tests, interviews, questionnaires, and observations. The collected data is then analyzed quantitatively using the t-test. The results showed that the validity of android-based gymnastic learning media is actualized from the results of the validity of materials, media, language, and assessment instruments The ability to roll forward straddle is on very high validity criteria. The practicality of android-based gymnastics learning media is on very practical criteria. The effectiveness of android-based gymnastics learning media is on the criteria very effective. The average levels of Ability to roll forward straddle on all three sections are 83.65, 84.65, and 73.45, respectively. The average increase scores on each section were 0.61, 0.65, and 0.64.
