Abstract

Students' low mathematical communication skills are the main problem that needs to be addressed by an educator. Learning should be designed through problems that allow students to communicate mathematically better. This study aims to produce mobile learning-based learning media with a Contextual Teaching and Learning approach that is valid, practical, and effective for improving students' mathematical communication skills. The subjects of this study were tenth-grade students of SMA Negeri 8 Batang Hari in the even semester of 2024/2025. This type of research is Research and Development with the ADDIE model. The results of this study indicate that the quality of the developed mobile learning learning media has valid, practical, and effective categories. Validity can be seen from the results of expert validation in the fields of media and learning materials, which show that mobile learning is good and feasible to use. Practicality can be seen from the perceptions of students and teachers who gave positive responses to the developed mobile learning, and effectiveness can be seen from the increase in students' mathematical communication skills with a comparison of pre-test and post-test results using the N-Gain test with a score of 0.71 in the high category. Thus, to improve students' mathematical communication skills, mobile learning with the contextual teaching learning approach that has been developed can be used.

Abstract

This research aims to describe the implementation of the use of the problem based learning (PBL) model in data presentation material assisted by diagram board media in class V elementary school to improve student learning outcomes. This type of research is Classroom Action Research (PTK). Research instruments include documentation, observation sheets, tests and interviews. The research subjects were class V students at SDN 80/I Muara Bulian, totaling 19 students, 11 students and 8 female students. The results obtained include the pre-action stage, the average score obtained by students was 43.33, then in the post test carried out in cycle 1 there was an increase in the average score of students, namely 66.31, and in the post test carried out in cycle 2, there was another increase in the average score, namely 80. Based on the results of the research, it can be concluded that the application of the PBL model assisted by diagram board media in improving student learning outcomes in class V elementary school has gone well and has increased
