Turtle Graphics (no longer just LOGO) got a lot
of buzz a few years ago. math for the rest of us.
i visited the Lamplighter School in Dallas,
Texas. the program,supplied with many PCs by
Texas Instruments, had been set up by Seymour
Papert and enthusiasticly covered by Steward
Brand in his book The Media Lab.
when i was graciously given a tour, the Turtle
Graphics users comprised one kid designing an
arcade style video game and another noodling
around without writing code. all the energy had
moved over to Multimedia. the same thing was
happening in the teaching lab at Cal Poly SLO,
from what i have seen, it takes a teacher who
loves math, loves graphic design, loves
programming and loves teaching.
when mac came out with LOGO for Mac, i was
expecting clickable objects and programs that
would let students learn even without that
special teacher. what i saw was mainly line
driven. not really much different than non-object
to get Turtle Graphics back on the map will
require standalone teacher-proof teaching
sequences that capable teachers can extend in
their own way. i still think TG is the most
intuitive way to learn geometry and programming
and look forward to the new release.
