Development of android-based mobile learning media to increase learning results in vocational high schools

The purpose of this research is to produce android-based mobile learning media and to determine its effectiveness on student learning outcomes. This research is a type of research and development method conducted through the ADDIE model, so this research is a type of research and development. The media was validated by experts in three fields, namely material, media, and language. The test subjects were 32 vocational students majoring in Automotive Engineering. Data analysis conducted to evaluate the effectiveness of the media involves the use of n-gain score and paired sample test statistics. The results of the study prove that, (1) the mobile learning media developed is very feasible to be used in learning activities for equipment and supplies in the workplace based on the results of validation by material experts of 87.8%, language experts of 95%, media experts of 90.5%, and student responses of 93.3%. (2) mobile learning media is very effective to use and has a significant effect on improving student learning outcomes, based on the results of the average score of the field trial after using mobile learning of 86.94 with a gain value of 0.72 with high criteria and t-test results of 0.00 <0.05. (3) the application of mobile learning as learning media makes it possible for students to learn independently.
