Comparison of The Implementation of Direct Instruction, Problem-Based Instruction, and Cooperative Learning using Cabri 3D on Geometry

Abstract

This study aims to compare the implementation of 3 teaching strategies; Direct Instruction, Cooperative Learning, and Problem Based Instruction in the geometry classroom. Cabri 3D was used as media to teach geometry in a classroom where 38 students participated as the subject in this study. The instructions were implemented for 8 meetings to evaluate the practicality of Cabri 3D in Direct Instruction, Cooperative Learning, and Problem Based Instruction. The result indicates that each instruction has their own advantages but generally, Problem Based Instruction is the best teaching strategies to conduct geometry class. The practicality based on the average score of implementation in Direct Instruction is 2.47 (good), Cooperative Learning is 2.54 (very good), and Problem Based Instruction is 2.49 (good). Teacher activities in all of the three learning instructions are in a good category, Direct Instruction is 3.67 (good), Cooperative Learning is 3.82 (good), and Problem-Based is 3.99 (good). This finding supports the theories in using Cabri 3D as teaching media in mathematics classroom.
