Understanding the Nature of Science (NoS) is now widely recognized as an important component in cultivating students’ scientific literacy. NoS can be manifested through textbooks used to facilitate learning of physics in the classroom. The purpose of this study is to describe the proportion of NoS represented in five popular physics textbooks used in Indonesian high schools and the strategy for presenting NoS in those textbooks. The data were obtained through analyzing the NoS aspects in five similar chapters of each textbook using the framework and scoring rubric. The results of this study revealed that none of the five books analyzed contains complete aspects of NoS. The aspect of dimension of science shows the highest proportion in the five textbooks. However, the aspect of inferential, tentative, and creative aspects are poorly represented or even not addressed at all. Besides, these aspects are mostly delivered implicitly. The results of this study are expected to be a positive input for the revision of the textbooks in the future.
