PENGARUH PEMBELAJARAN VISUAL THINKING DISERTAI AKTIVITAS QUICK ON THE DRAW TERHADAP KEMAMPUAN PEMECAHAN MASALAH DAN KOMUNIKASI MATEMATIS

Abstract

This study is based on low ability in problem solving and students’ mathematical communication. In order to overcome the problem, the study is done using Visual Thinking approach in learning activity with a Quick on the Draw activity. This is a quasi-experimental design with nonequivalent control group design and uses purposive sampling technique. Population in this study was VIII grade students of SMP in city of Pekanbaru, Riau year 2012/2013. Furthermore, the sample of this study was VIII grade students in a SMP of city of Pekanbaru, Riau. Instrument in this study was a test of problem solving ability and mathematical communication, attitude scale, observation sheet of teacher’ and students’ activities. Quantitative analysis was performed sing the average difference test. The result of the study showed that: (1) The increase in students’ ability of mathematical problem solving whereas the students received Visual Thinking approach in learning activity with the Quick on the Draw activity is better in comparison with conventional learning approach which reviews whole students and students’ mathematical prior knowledge (high, medium, and low); (2) the increase in students’ ability of mathematical communication whereas the students received Visual Thinking approach in learning activity with the Quick on the Draw activity is better in comparison with conventional learning approach which reviews whole students and students’ mathematical prior knowledge (high, medium, and low).
