The Development of Textbook Based on Constructivism in the Basic Mathematical Concept Course

Abstract

The purpose of this study was to know the validity of textbook in Basic Concepts of Mathematics course using constructivism approach. Subjects of this study were the Students Education Study Program of Primary School Teacher Education Pattimura University in the Academic Year 2019/2020. Type of the research was the develop using 4D development research design which includes four phases such as defining, design development, disseminate. The result show that the validity of textbook in basic concept of mathematics course on constructivism was very valid. By using the textbook, students become actively participate, independently learners, and active to develop their own knowledge.
