[Edu-sig] Re: Long Integer Fractions

[Matthias Felleisen]

  Please note that I'm not pushing anything re AP computer science.  
  I'm simply prototyping how to teach a regular, garden variety 
  mathematics curriculum with some computer language as part of 
  the mix.  This is the next step after the current "graphing 
  calculator" craze is over.

Of course, *I* know and understand what you're doing. The problem is that
others won't. We wrote a proposal to NSF in 1996 to re-do the mathematics
curriculum with Scheme. We also threw in physical sciences and the dismal
science. As soon as you mention "computer" you're no longer considered a
"math" person. They need to bring in a "computer specialists" even if they
agree that what you do looks like math. Of course, the CS person won't have
a clue about this funny stuff you're doing. But then again, this fraction 
stuff looks like exact real arithmetic and, oh yes, btw, that was done in
the AP CS case study from 1994.7 to 2000.5, so you're behind. 

See how it works? Been there. Done that. Next? -- Matthias
