Barry Garelick told me to go find Ralph Raimi's web site and read his articles.
This is an excerpt from the one I started with:
If I were asked what seriously could be done to teach something
useful in the name of math to this kid, I would advise starting with the
arithmetic of fractions, i.e. what she failed to learn in the 5th and 6th
grades and since, and their applications and meaning of course. I believe
this could be made interesting to her once she knew she didn't have to
learn all those symbol manipulations she has been plagued with these last
five years. But there is nobody to do this for her, and there is no clear
incentive, since all she thinks she needs is to pass the next few exams.
Even with time and a knowledgeable teacher as private tutor,
fractions might not make it past the starting gate, since she has been
persuaded that her calculator has rendered them unnecessary.
Read the whole thing.
