Contextual teaching books connect theories, phenomena and problems encountered so students can implement theories, concepts and principles that have been learned with everyday life. The purpose of this study was to find out whether the presentation of physics textbooks for Class XI High School 1 Semester 1 had facilitated the implementation of a contextual approach in high school. The type of research used is descriptive research and the approach used is a qualitative approach. The sampling technique uses purposive sampling. The research instrument used in this study was a statement sheet in the form of statements according. The data analysis technique used is the content analysis technique and processed with percentages. Based on the research conducted, it was found that the results of this study were presented in the fourth analysis of physics books in class XI in the first semester which facilitated the implementation of the contextual approach. The book that has been very facilitating and suitable for use by the school is Yrama Widya's book. The Yrama Widya book has the highest and stable value in each component of the CTL assessment with an average value of 82.3%.
