This study aims to analyze the development of mobile learning in learning media to improve digital literacy and student learning outcomes in physics subjects. The method used in writing this systematic literature review is to search for the literature using a database on Google Scholar. The results of the study show that the use of mobile learning in student learning can be used as a learning support tool, media and learning resource and can be applied at the student level. The benefits of using mobile learning in learning are that it can facilitate the teaching and learning process both in the classroom and outside the classroom, attract students' attention and can generate enthusiasm and motivation in learning so that the material being delivered can be conveyed properly and can be understood by students, besides another benefit of using mobile learning is that it can support students towards independent learning. The development of mobile learning as a learning medium has been carried out by several researchers, who develop mobile learning. The results of the development carried out indicate that the media developed is more likely to focus on the teaching material only. Mobile learning developed is focused as a means of practicing working on questions that can provide various types of questions that are varied and challenging.

This study aims to: (1) Test the feasibility of student worksheets based on the practice of Problem based learning models in social studies (2) Test the effectiveness of student worksheets based on Problem based learning models for changes in student learning outcomes in social studies. The research on the development of this learning media is based on the ADDIE model. The research subjects were seventh grade students of SMPIT Insan Permata Bojonegoro. The selection of subjects by random or random sampling was class VII A as a treatment class with 30 children and class VII B as a control class with 30 children. The results of this study indicate. First, teaching materials in the form of worksheets for social studies -based practicum students in PBL models according to learning experts fall into the criteria of "feasible". According to the material expert on the contents of the material on the social studies student worksheets Integrated practicum based on the results of validation stated "very feasible". And the validation results from media experts get the category "feasible". In general, student worksheets fall into the "very feasible" category. The effectiveness test shows that there are significant differences between classes using LKPD and classes that do not use. This is indicated by the average posttest values between the experimental class and the control class which also differ significantly.

<p><em>The research objectives are to (1) produce videos that are suitable for use in flipped classrooms and (2) produce videos that are effective in flipped classrooms. This development research uses the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. Data collection techniques through questionnaires, tests and interviews. The results of the study are as follows (1) media expert validation is 100%, material expert validation is 98.33%, learning design experts are 84.72%, individual trials are 98.33%, small group trials are 95.63% and field trials of 95.50%, so video development is very feasible to use in flipped classroom learning (2) comparative test Pre-test Post-test using independent Sample T-Test. In the table of equal variances assumed to be significant (2-tailed), the written data is 0.000, meaning &lt;0.05, so there is a significant difference between the treated class and the control class. From these results it can be concluded that the use of video media is very effective in improving learning outcomes.</em></p>
