Abstract
This study aims to obtain a profile of the level of understanding of concepts and mental models of students in grades 10, 11, and 12 regarding the graphical concept of straight motion kinematics in high school. This research is descriptive research. The research subjects were 25 students for each class 10, 11, and 12 who were taken by purposive sampling. The research data collection instrument used a test of understanding the concept of straight motion kinematics graphs in the form of open descriptions. The data analysis was carried out in two stages, the first stage was the analysis of the level of understanding of the concept and the second stage was the analysis of students^ mental models. Analysis of concept understanding data obtained by students^ mental models at the scientific level for students in total got a proportion of 20%. In the mental model, students at the Syntetic level obtained a proportion of 16.7%. Meanwhile, the mental level model dominates by reaching a proportion of 63.3%. From these different proportions of mental models, it can be used as a consideration for educators in choosing learning strategies in the classroom.
