This study aims to determine the increase in problem solving skills of students in MAN 3 Yogyakarta through audio visual media in Problem Based Learning (PBL) model. The method used in this research is a quasiexperimental design with an experimental design, namely one group pre-test-post-test design. The sampling use purposive sampling technique with participants were 31 student from year 11 class in MAN 3 Yogyakarta. The result is showed that there was an increase in the problem solving skill of students of MAN 3 Yogyakarta which was indicated by the results of the Wilcoxon test, it was known that the significance was 0.000 < 0.05. It can be concluded that problem solving skills improve by applying audio visual media in a problem-based learning model in MAN 3 Yogyakarta.

This study aims to develop audio-visual media for distance learning in high school physics material with the optical instrument sub-chapter. Distance learning uses a website-assisted problem-based learning (PBL) model. The learning website from the ministry of religion is used in this distance learning. The development method used in this research is the four-d (4-D) model. Expert validators and class XI students of MAN 3 Sleman as subjects in this study. Validation sheets are used to obtain expert validation results and response sheets to obtain student responses. Expert validators stated that the learning media developed were valid and included in the "very good" category. Student responses were also in the "very good" category. So that the audio-visual learning media with a problem-based learning model for distance learning is declared feasible and can be used in learning activities.
