[Blindmath] Tactile Math Graphs and additional comment

I am just the parent of a visually impaired high school student who is
taking Math 2 which is Intermediate Algebra. I agree on the tactile graphs
because of lot of states have very restrictive verbal description policies
which would make it difficult to gather enough information to really be
helpful. My other thought is to ask the professors if there is a nonvisual
way to learn the same concept.
For instance, my son is currently learning about Quadratic equations and a
lot of his work involves converting from standard form to intercept form to
vertex form. If you understand how to do this and understand the different
components of the standard equation - it actually tells you quite a bit
about the graph without having to see the graph. You can determine how many
roots it has, whether they are real or imaginary, whether it has a stretch
or a shrink, whether it opens up or down and also whether it is inverted or
reflected all without actually looking at it.
There are problems that you will be required to look at and that is why you
should get the tactile diagrams. However, if you get your teachers to teach
you a nonvisual way to determine as much of the information as you can - it
will help some. I have found that once a teacher figures that out - they
kind of get into a pattern of teaching you that way when they can.

Sorry, but verbal descriptions of graphs used in algebra are seldom useful.
Get tactile diagrams.

You will need someone to explain the graphs to you.
I'd suggest you ask your professor to do this, explain that you want to
understand this, that you can't access the graphs so you'd like them to
describe them.
Go in with the attitude that you care and want to learn this.

Subject: [Blindmath] Math graphs
Hello,
My name is Catalina. I am taking a math class and use Braille.
I have a difficult time with my class because the 3 chapters of my math
textbook at my college are almost entirely graphic. I told the instructor I
cannot do it since it is very hard to understand the graphs for this
intermediate to advance algebra class. But they tell me they don?t know how
to accommodate me. They use MyMathLab, which is not accessible for me.
Does anyone have any suggestions, please? How does a blind student navigate
a textbook that has a lot of graphs?
Thanks a lot,
Catalina

If tactile diagrams are not available then audible spoken descriptions can
work. I went through college with no tactile graphs. I am 100% blind and
took all the way up to calculus 3. It can be done. Now that doesn't mean
it is a perfect situation but it can be done.

Dear All,
The graphical math in Wikipedia pages appear to be in Latex when traversed
by a screen-reader. Although doable, Latex reading by screen-reader is not
efficient for me. I wonder if there is a plugin for web browser which
converts the latex to something more convenient. I've heard about Math
Player and had it installed on my computer, but I haven't seen any change.
Does math player address my issue? Any other suggestions?

MathPlayer doesn't address this. We did it in a prototype, but Wikipedia is
moving (slowly) to using MathJax for MathML rendering. There is an
experimental version of using MathJax for Wikipedia, and you can give it a
try. Not all math is on the wikipedia pages is done with TeX (and hence can
be converted to MathML), some is "HTML math" (using sup, em, etc).
To use MathJax on Wikipedia, you need an account on wikipedia. Go to some
wikipedia page besides the front page and there is a "create account" link
if you don't already have an account. After creating the account, read the
instructions at this link for what you need to set:
http://www.mediawiki.org/wiki/Extension:Math/MathJax_testing
You will likely need to tell MathJax (via the right button content menu) to
use MathML (which causes MathPlayer to run). It is under Math
Settings:MathML Renderer: MathML
I hope it works for you. Some day, Wikipedia will turn this on by default.
