The sample of research was the four most used books in West Sumatera High School, three of which are recommended by the government. The research instrument used was very valid. The research instrument used 10 SPS components, which are translated into 31 SPS indicators. Each indicator is explained by one to three instruments. Data collection technique used is the study of documents. Data analysis technique used content study. The results were obtained that the book used as a reference for learning physics in Class XI High School Semester 1 has facilitated observational skills indicators, but has not facilitated the skill indicators of asking questions.
