Validity of integrated natural science teacher's book with immersed type that contain character on subject of bio-electrical energy by using science process skills approach

The learning of integrated science in SMP/MTs is supported by the resources of the student's book and teacher's book. The teacher's book is guide for the teacher in learning preparation, implemention, and assessment. The aim of this research is to know the validity of Integrated Natural Science (IPA) Teacher's Book with Immersed Type that Contain Character on Subject of Bio-Electrical Energy by using Science Process Skills Approach. The kind of this research is Research and Development with using research Plomp model. The instrument of the research is the observation sheet in the form of teacher validation questionnaire. The data analysis is descriptive using Likert scale technique. The result of the research shows that the Teacher's Book with Immersed Type that Contain Character on Subject of Bio-Electrical Energy by using Science Process Skills Approach which is valid category (0.78) by expert and by practitioner.
