Evaluation of Educational Graph Creation Tool based on Natural Mathematical Description

Abstract

The procedure used to input an equation and define a graph using existing tools remains unnatural and troublesome for novice students. To address this shortcoming, we propose a graph creation tool based on a natural mathematical description. In this study, we improved the predictive conversion speed of the mathematical input interface used in the previous graph creation tool. The results of a performance comparing test showed that the mean task time when using the proposed tool was approximately 1.2--1.7 times faster than that using GeoGebra.
