Abstract

Abstract - This research aimed to produce valid, practice, and effective learning materials using realistic mathematics education. Moreover, the learning materials designed is intended to help students improve their mathematical disposition and mathematical connection ability. This is a developmental research using the 4-D model. Instrumentation consists of observation sheet, lesson plan, teacherís and studentís book, mathematical connection test, and questionnaire on mathematical disposition. The first trial took place in class VII-C and the second trials in class VII-B SMP Swasta Siti Hajar Medan. The result of the study indicated that learning tools (materials) developed valid both in terms of content and construct, practice, and effective. The students mathematical connection ability increased within medium category, whereas their mathematical disposition increased from the first to the second trial.
