A very nice article! It really makes me think, though, if it's so hard
to get students in general to follow STEM subjects in college and
beyond, how much harder must it be to get blind students to do so.
There is so much against blind students in the STEM subjects, students
will quickly get frustrated.

One simple example: I'm going into an intermediate algebra class. They
are changing the way they teach the class, using 'modules' on-line.
These modules are not accessible and they know it. Disability Support
Services has promised the math department that they will not register
any blind or visually impaired students in the module classes because
of the accessibility issues. So, instead of geting to try out the new
system, which has been said to be better (though I have no clue how),
I'm stuck in one of the few algebra classes that aren't following the
module system next semester. Math is already difficult for me, because
I have dyscalculia and because I don't know Nemeth very well, but
layer on top of that I'm going to be in a class that is not
up-to-date? It frustrates me, and I just thank goodness I'm not trying
to be a math or science major, because accessibility would continue to
be an issue in the higher classes. I'm having a hard enough time
without the accessibility issues.

My two cents,
Jewel
