[nabs-l] graphing and graphing calculators

[Ashley Bramlett]

Arielle,
I'm also curious to know what
tactile drawing kits other students taking this type of class used.
I know there are several out there, but what would be good for math?
Here's the thing. You know graphs are not just lines; they curve and some 
are at odd angles.
In my experience, tactile kits such as the draftsman kit
are best for representing raised lines not circles or half circles.

I mainly see this friend at beep ball which will end soon.
But I'm hopeful to stay in touch to see how her class ends up going.

Look forward to hearing some ideas and knowing what excel can do, if I need 
it for a class or personal use.

Thanks.
Ashley

Hi Ashley,
If she did fine in honors Algebra I then she should have the chance to
at least try Honors Algebra II. I would need to know more about the
curriculum to offer specific solutions, but I personally believe that
graphs are overrated. Like you, I always solved equations
algebraically and wrote down text descriptions of the graphical
solutions instead of actually graphing them. I had tactile graphs in
my Braille math books and worksheets, which helped me to visualize the
basic kinds of equations. But once I had seen the Braille versions I
could visualize graphs in my head when I was solving equations. Keep
in mind, I took honors Algebra I and II, advanced precalculus and
advanced-placement calculus without a graphing calculator. Every once
in a while I skipped an equation that could not be solved by hand but
that was rare. I have also taken four statistics courses in college
without ever using a graphing calculator or drawing graphs So I think
this student should at least be able to discuss the option of solving
problems mathematically rather than graphically, because after all,
the skill that needs to be learned in Algebra II is how to solve
equations, not how to draw lines. I also have a hard time believing
that a reader wouldn't be an acceptable accommodation for state tests.
What accommodations are acceptable, then, if a reader is not? If
technology is not allowed, do sighted students still get to use
graphing calculators on these tests? What is the blind student
expected to do, just skip those sections of the state test?
That said, though I personally think graphs are overrated, some blind
mathematicians do find them useful. There is an audible graphing
calculator and there are a number of tactile drawing kits. I'll post
your question to the BlindMath list and forward any responses I get to
this list (as other high school students here might have similar
questions).
As for an accessible scientific calculator, can this student use Excel
on the computer, or do they have a Braille notetaker? Either option
should be sufficient.
