Teaching Approaches using Graphing Calculator in the Classroom for Hearing-Impaired Student

Abstract

In the classroom for hearing- impaired students it is difficult enough to use spoken language as a means of communication owing to hearing impairment. The consequence of it leads to poor chance for them to negotiate with their teacher and the other students about mathematical meaning. Thus it is difficult for them to make sense of mathematics as many researches also show.

In order to solve this state graphing calculator enables us to take teaching approaches. We focus on two approaches; step by step approach and visualization approach. It is thought that these approaches stimulate for hearing-impaired students to make sense of mathematics.
