This study aims to analyze the effect of the concept attainment model with the demonstration method on the mastery of student physical concepts. This type of research is a quasi-experimental with pre-test and post-test control group design. The population in this study were all students of class XI MIPA in one of the state high schools in West Lombok. The sampling technique in this study used a purposive sampling technique, so that the sample used in the study was class XI MIPA 3 as an experimental class and class XI MIPA 6 as a control class.
