[blindkid] Math technology

You forget the raised-line drawing kit. And school districts in my 
experience don't often have the real geeks of which you speak below. It's 
plug-and-play all the way!

The key is to get the adaptive person who probably knows the computer
technology of the embosser and the calculator, together with the math
teacher who knows how graphs and the mathematical component works, as
neither will be able to help your child on their own.  But geekese is pretty
similar in dialect between math geeks and computer geeks, so they should be
able to figure it out.  And, yes, graphs and some type of graphing
calculator will be extremely neccessary, not "if it is absolutely
neccessary".  Tracing tools are alright, but there must be graph paper
behind the tracing, as a general shape of the graph will not be helpful, if
the child needs to assertain which exact point the vertix of the perabola
passes through, or whether or not the sine curve is passing through the
origin or not.  I hope this helps.  Oh, and as to affording it.  If the
school fights it, remind them that A. she needs it, really and truly needs
it, B. they can store it carefully and use it for other blind and VI kids
coming up in the grades below her and in other schools in the district and
C. they are by law required to provide her equal opertunities in education
in the least restrictive environment, which includes adapting the graphs and
graphing technology for any level of math course that she is cognatively and
accademically ready for and that is offered by the school.

I'd try to ascertain (a) who her algebra teacher will be next year and then
talk to him/her about the problem, emphasizing that you will assist with
drawing of raised-line graphs and perhaps showing him a Sewell raised-line
drawing kit to show how impromptu graphs can be made and (b) get a copy of
the book to see how much it relies on whizbang technology as opposed to
good, old-fashioned reasoning skills. Bear in mind that I am a strong
advocate of writing out math problems on a brailewriter.

If a graphing calculator proves absolutely necessary, I'd go with one that
can produce graphs on a Tiger embosser although for the life of me, how any
parent can afford one or, for that matter, how a school district can
successfully use one when it probably hasn't got anyone with the requisite
skills is beyond me.

But one should always approach the problem from the standpoint that it's
solvable, because it is. I hope that Steve Jacobson chimes in on this one
also.

so, Michael what suggestions do you have for her daughter as she works to
maintain her grade average and commitment to academic enrichment?

Pat:

I'm sure many will disagree with me here but I could never fathom how audio
could accurately convey graphics to the blind. In my book, graphs are only
crutches to illustrate abstract concepts and math teachers are only as good
as they can deal with the abstractions without needing to "picture"
everything.

My daughter will be taking Algebra II next year in 9th grade. She uses
Braille/Nemeth texts with tactile graphics. She's gotten by just fine with
relatively low-tech math tools.

We are wondering if it would be useful for her to start using an accessible
graphing calculator. Does anyone have any practical advice on using one of
these programs? I am looking into the Audio Graphing Calculator from
ViewPlus and Math Trax from NASA. They both produce an audio signal
representing the shape of the function, while the AGC has the advantage of
being able to produce tactile graphs on a Tiger embosser. Maybe there are
other products available? Our school district has no experience with any of
them. Does anyone¹s teenager think this software is worth learning?

We are a little nervous about this, because our experience has been that,
math is great because you can pretty much always count on a Brailler, paper,
and sticky dots from the hardware store to NOT fail and to NOT require
specialized training that gets in the way of actually learning the
material...

Thanks in advance for any help.
Pat
