Improving High School Student Learning Outcomes in Online Lessons of Elasticity Physics Using Problem Based Learning Model. This study aims to improve physics learning outcomes on the concept of elasticity through a problem-based learning model. The subjects of this study were 22 students of class XI-MS at SMA LAZUARDI GIS Depok. This research is a qualitative research using classroom action research (CAR) which refers to the model of Kemmis and Mc Taggart which was conducted in two cycles. Each cycle consists of four stages, namely: 1) Planning Action, 2) Execution of Action, 3) Observation of Action, and 4) Reflection.The results of this study indicate that the application of the problem-based learning model can improve students' physics learning outcomes in the optical geometry concept of students. The mean learning outcomes of students in cycle I and cycle II were 74.7 and 85, respectively. The number of students who had reached a score above the KKM also increased to 100% in cycle II compared to 60% in cycle I. This clearly shows that the results of learning physics on the concept of elasticity of students have increased significantly compared to cycle I. In addition, the problem based learning model is quite effective in being applied to the concept of elasticity.
