The purpose of this writing is to describe efforts to improve the quality of physics learning, especially the high school level by applying the Problem Based Instruction learning model. This writing is motivated by less optimal mastery of students on physics material and lack of interest in students to study physics. For this reason, there is a need for efforts to increase student learning motivation in studying physics, in order to be able to improve the quality of its learning outcomes by applying the Problem Based Instruction learning model. In the Problem Based Instruction learning model was developed to help students improve the ability to think, the problem of problems, and intellectual skills, and learn through learning experience in real life. The method used in this writing is with the literature study by reviewing several literature and analysis The results of writing show that the application of the Problem Based Instruction model can be a solution to the problems encountered in the teaching and learning process in the classroom. The problem based instruction model is applied to students in high school with several steps, among others: (1) Learning begins with the submission of material by teacher lectures and questions and answers, (2) The teacher suggests the issue of the material being discussed in everyday life, and students are given individual assignments to solve the problem and design their follow-up, (3) the teacher forms a group, (4) the answer to the assignment was asked to be discussed first with his group friend.
