Pretty much the demo that wowed them in Anaheim and Atlanta:

Taking a break now, will be scanning later for typos.

If you can think of anyone who would be interested, please pass it
along. We're talking Lisp jobs here!

Cool program, from my own little experience teaching algebra mostly to
my brother
the only effective thing to make student understand is not to tell
the solution,
nor point their mistake,but solve the problem with different numbers
so the student will get the pattern and understand where they make
mistake
for themselves.

Yep. One big advantage of the new software is what I mislabel "cloning", since clones are identical (or so I understand). Anyway...

The old program forced the student to go to a problem generation dialogue and then specify type, subtype, and difficulty to generate a clone. But if they are stuck they do not know what to look for? Never mind that that is so much work they will not do it.

The new program automatically generates a clone with one click, of the whole problem or of the last correct step, as seen here:

The astute yobbo will notice a flaw in the clone: unlike the original, the clone does not require the fraction be reduced. Well, it is not really a flaw, I just have not finished that bit yet. :)
