Audio Description: Part ten; production of tactile graphics; example one.
Teacher: This is a test that was for a Geometry class and when we did it we started out not knowing exactly what to expect from the class.
So, at the beginning the class was unmodified except for the Braille and with one of the examples here,... it's two parallel lines with two intersecting lines, and we brailled it as if, just like it is in print and... expected John to get all of the information off of the graph.
What we found is that it was a lot of information that he had to scan for and a lot of it was getting lost. So, for example, he had to find angle 1, which is all the way up here, and angle 14, which is down at the bottom.
And meanwhile, we visually can locate the information fast, whereas he would be scanning the whole page and it would take him a couple minutes to find the information. Besides the fact that he had to find the information, the questions then were on a separate sheet.
So we would Braille the questions in order, so question 5 would be here and then he would have to flip to the back of the test to find the graph... which we then labeled that the graph was for the diagram for questions 5 through 11. But there was a lot of flipping back and forth which caused some problems.
To make these graphs we used the Braille writer, we used a glue gun and then we used, to do the lines, the intersecting lines, the Braille writer to do the parallel lines and then just Brailleon to put on the points.
