The student books needed are very important in an effort to achieve the objectives of learning Physics carried out by students. This type of research is research and development. This study aims to see the effectiveness of student books with the Problem Based Learning (PBL) model to improve 21st century skills on temperature and heat materials for students of SMAN 3 Lengayang class XI.MIPA1. Effectiveness data obtained from students in the form of essay test questions. The research subjects were students of class XI.MIPA1 with a total of 35 people. The research instrument includes essay test questions. Effectiveness data analysis technique using descriptive percentage. The average N-Gain value obtained is 66% in the medium category.
