Application Of Brain Based Learning (BBL) Models Based On Saintific Approach With 3D Cabries In Geometry Material To Increase The Ability Of Mathematics Communications For Students Of SMAN 1 Karang Baru

Abstract

Abstract— The aim of this study is to know the improvement of learning by using Brain-Based Learning (BBL) model based on scientific approach with Cabri 3D againts student’s mathematical communication ability. This research is an experimental Quasi Experimental with Design Nonequivalent Control Group Design, which is research subjects were not randomly grouped with the provision of preliminary and final tests. The population of this research is all students of class X SMA Negeri 1 Karang Baru, Aceh Tamiang. Two classes were selected as research samples, namely experimental class and control class. The instrument in this research is a test of Mathematical Communication Skill. The research data was analyzed by using T test. The result of this research indicates that learning by using Brain-Based Learning (BBL) model based on scientific approach with 3D Cabri is better than using scientific learning for improving mathematical communication ability for students.
