[nabs-l] graphing and graphing calculators

Thu Aug 23 05:01:30 UTC 2012

Hello,
If she didn't take Algebra 1, she is going to die in Algebra 2. You need 1 
before you go onto 2, I thought I'd just through that out there.
Thanks,

Arielle,
Thanks. I told her to try it too.
She can always switch to regular algebra if things become difficult.

I might get more details as to what is required of students in algebra 2.
She will have braille math books so I assume this will aid her in
understanding the graphs and what they look like.
I'm sure she uses a braille notetaker but I'll ask. I think excel and the
scientific calculator on the notetaker would provide access to many
of the functions she needs. She could do the problems by hand, but it seems
to me it would be more efficient to use a calculator like everyone else.
I wonder if she would be behind as well when they have calculators and she's
doing it by hand.

What does excel help you do? Does it graph parabolas or matrices problems?

I'm not sure how blind students would graph usually; I used vision for that
part.
I know APH has the tactile graph paper, but it does not have many squares
and does not seem big enough to put multiple lines on it; you know sometimes
you have to graph two or three lines to see where they intersect.

So how would you represent a dotted line for unequal to? Sighted people
shade in parts of a graph to represent something.
We also had to graph inequalities on number lines. The visual way is to
darken part of the number line and draw an arrow to the side you need. Like
an arrow to the right of 1.
Also how could you graph a line graph that curves? I thought of wiki sticks,
but those probably wouldn't be long enough.

I remember graphing some, but as I said, I solved a problem algebraically if
that was an option.

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.
Arielle
