The Development of Learning Materials base on Geogebra for Prospective Teacher

Abstract

The purpose of this study is to produce a textbook to improve the ability of prospective teachers in geometry. Textbooks prepared using research and development methods. Textbooks are evaluated based on the feasibility aspect of the material, appearance and language. Research shows ratings material is 85% (very good), the illustration is 84% (excellent) and conformity assessment according Indonesian language Grammar and Structure is 85% (excellent) and the mathematical notation is 86% (very good). Thus the textbook developed have completeness of the materials, the material accuracy and presented with illustrations can develop an understanding and ability of prospective teachers in geometry.
