Even if a blind student has readily available transportation and is able to possess all the necessary materials for a class, understanding concepts, ideas, and thoughts expressed by the sighted can be a formidable task for the young and relatively inexperienced blind student. It s not very easy for older students, either. This challenge to the blind is not often or well understood, and less frequently fully appreciated, by many sighted educators. A sighted student uses his ears, eyes, and hands both to touch and write when learning school lessons. Today even the poorest schools use audio-visual methods for teaching lessons.
Teachers simultaneously use pictures to illustrate and words to explain some issues of a lesson.
For instance, a teacher who wants to show his students the nations of Asia may use a map of different colors and shapes, as well as the names of the nations printed on map. The teacher may show the students flags of each nation with outlines of their various designs and than have the students color in the national colors and print the name of each country below the flag. Another teacher who wants to help his students learn about the natural resources of the nation, or even his own province, can draw on a black or white board using colors and shapes. Such a lesson could sound like this to a blind student. The area colored in brown that I m pointing to is a forested area has a good potential for harvesting wood.
