Abstract

This study aims to determine the profile of students^ conceptual understanding in the material of Newton^s laws. Understanding the concept is a very important component in learning physics. The research design used was a post-test only one group design. The research subjects consisted of 36 students in class X SMA, 19 female and 17 male, students with an average age of 16-17 years. The research instrument consisted of 15 multiple choice questions about material of Newton^s laws. The results showed that most of the students still had a concept understanding that was lower than 0.0 logit. There are differences in conceptual understanding between female and male students at certain cognitive levels. The results of this study can contribute information and descriptions to the teacher about the condition of students^ conceptual understanding abilities. Teachers can make various kinds of efforts and innovations in improving students^ conceptual understanding.
