In the process of problem solving, students must be able to focus on problems, describe problems in concepts, plan the solutions, implement the plans and evaluate the solutions. This article discusses the effectiveness of the inquiry model integrated with advance organizers in enhancing students’ problem solving ability in concepts of work and energy. This research was conducted with one group pretest-posttest design at two different senior high schools. The research instrument used was five questions of the essay test. The enhancement of problem solving ability was analyzed by N-gain score. The results showed that the problem solving ability of two groups increased in medium category for each submaterial, while based on the problem solving stage, stage of focus the problem, plan the solutions and implement the plan increased with the high category in one group, while the other stages were in the medium category. The results of this study have proven that the inquiry model integrated with advance organizers is effective in increasing students’ ability to solve problems in the concept of work and energy.
