Pengembangan Bahan Ajar Materi Perbandingan Bercirikan Realistic Mathematics Education

Abstract: The aim of this research is to delevop a proportion textbook characterized Realistic Mathematics Education (RME) which the criteria are valid, practical, and effective. The textbook is developed by plomp model which has three stages; preliminary research, prototyping, assessment. Validation result shows the textbook satisfying valid criteria (81,25). Based on result of development study in MTs Almaarif 01 Singosari, the texbook satisfies practical criteria. All of activites both teacher and student succeed (100), even though there are some weaknesses and student’ questionnaire show students response indicating are very positive (98,33) toward the textbook.
