[Blindmath] Understanding math versus passing standardized tests of math

Sun Nov 24 22:00:39 UTC 2013

In the better designed tests which have been put into braille, the transcriber has the 3 d cube drawn but below the diagram of that is the cube in six sections...that made so much sense to my students...that is how they are given in NYS exams anyway..

Even on the standardized test, it's not fair for a blind person to have to interpret 2-D representation of a 3-D object when that entire representation is based on a lifelong visual perception. I don't like those tests much, but their makers care about whether they're biased toward all manner of minority group, but apparently don't care if they're fair for blind people.

However, the quality of this "creativity" varies wildly amongst educators. You get even more variation when you get to university where professors can have all sorts of competing priorities and demands on their time.
