[Blindmath] Explaining Rotations to a Scribe?

Wed Sep 28 01:08:51 UTC 2016

You can ask for a math professor to be the scribe. I would also suggest that you use manipulatives and have someone videotape you as you explain it and manipulate the materials. Then send the professor the video. That takes out the need for a scribe

I also don't think it is a limitation of blindness. Blind people would be doing their own math more and communicating with sighted people mathematically in an understandable way if more attention or give into it.

Hello,

I understood your description perfectly well. The problem is not one of communication, but one of who you are communicating with.

I feel that while you need to ask this question you put yourself at risk of having your ability measured against your ability to convey a message to a person who is less than suitably qualified to understand it. The rest of the class need only explain themselves to a higher authority (the marker, not quite a god) while a blind person often needs to explain themselves to a third party. This is actually not a fair expectation of a student and the person administering the education or assessment ought to know what they are loading on their students.

I was fortunate to work with enlightened staff who realised that if they wanted to know what I was capable of, they needed to make sure it was my work and understanding they were seeing. That meant using postgrad students in mathematics or the appropriate discipline to act as scribes (we call them reader/writers here) in almost every test or exam. I was also lucky to get the right access to willing postgrad students and under-employed staff to help tutor me as and when required.

As a consequence, my lecturers, many of which are now colleagues, know what I was able to do for myself and what was a limitation of my blindness.

Good luck finding the right person.
Jonathan

Subject: [Blindmath] Explaining Rotations to a Scribe?

Hi,

What is the best way to explain rotations for solids of revolution about an axis or line? As an example, how do I explain rotating the function y = e^2x and the line y = e^2 about the x axis? I have a feeling that we talked about this in Precalc, but if so, I have unfortunately since forgotten.

Thanks for your input,

Hunter
