Application Of Think Talk Write (TTW) Model Assisted By Geogebra To Improve Student’s Ability of Mathematical Concept Understanding In Class X of MAS PAB 2 Helvetia

Abstract

The purpose of this study was to improve students' ability to understand mathematical concepts by applying Think Talk Write (TTW) using GeoGebra in class X MAS PAB 2 Helvetia in the 2022/2023 school year. The subjects were 36 students of class X MIA 1 MAS PAB 2 Helvetia. Data collection techniques used are teacher observation sheets, mathematical Concept Understanding ability tests, and documentation. Researcher used type of classroom action research (CAR). Preliminary tests result obtained 5 students (13.89%) completed with an average of 53,99% (lower). In the tests cycle I, 4 students (44,4%) completed with an average of 64,40% (low). In the test cycle II, 33 students (91,67%) were completed with an average of 88,02% (high). It can be concluded that the application of Think Talk Write (TTW) using GeoGebra can improve the ability to understand mathematical concepts of class X MAS PAB 2 Helvetia students
