Problem solving is viewed as an essential part of physics education for teacher candidates in higher education. Thus, it was necessary to produce a fundamental of physics lesson book which focus on problem solving skills. The objective of this study was to produce a valid physics lesson book. This research was implemented in three phases, namely define, design, and development using the 4-D model of Thiagarajan. Data were collected through validation sheet and had been measured by the experts. Data then analyzed by using descriptive analysis techniques. The result show that the physics lesson book had been declared as a valid instructional device for improving problem solving of physics teacher candidates. http://pubs.sciepub.com/education/6/12/3/education-6-12-3.pdf physics lesson book metacognitive strategies problem solving
