The purpose of this study is to know the improvement of problem-solving ability in physics material (light reflection on concave and convex mirrors) before and after being taught by using Android-based learning media. The subjects of this study were the students of class XI MIPA 2 at MAN 2 Yogyakarta which consisted of 27 students. The design of this study is one group pretest-posttest and includes a Pre-Experiment study. Data collection techniques using problem-solving tests and technical data analysis using inferential and descriptive analysis. The inferential analysis shows that pretest and posttest come from homogeneous and normally distributed populations. The results of the study obtained that the improvement of students' problem-solving abilities is in the category of low and medium N-gain. © 2020 Published under licence by IOP Publishing Ltd.
