Implementation of Think Talk Write (TTW) Strategy to Improve Understanding of Concept and Communication of Mathematics

摘要

This study discusses about the students lack of understanding in recognizing procedures in formulating a settlement strategy and difficulty in stating events or problems in the language or symbol of Mathematics. One of the efforts to overcome this problem is to use a Think Talk Write strategy in learning. The purpose of this study is to describe the improvement of students understanding toward mathematical concepts and students' mathematical communication skills by using Think Talk Write (TTW) learning strategies. This research was a class action research (CAR) which is carried out in two cycles. Subjects in this study were fourth grade students totaling 32 people at SDN 145 Pekanbaru. The research data was obtained from observing student activities and understanding concepts and students' mathematical communication skills. The results showed that TTW strategies can improve students' understanding about concepts and mathematical communication skills.
