Actually, I was using graduate as a verb.. the objective is to get students 
out the door at the other end. Pass the exit exam, get them accepted to 
college, what have you.

And that is a noble goal.  Hopefully, all this discussion has prompted some 
ideas on how to get there?

No, the article was more along the lines that schools spend precious class 
hours doing what is essentially user training for a single application, 
rather than generic skills.  The thrust was (this IS Phi Beta Kappa, after 
all) that society would be better served by spending tax dollars to give 
students a good liberal arts education, and let the employers pay for 
training people to use a particular software package.  I'll try and find 
the exact reference (oddly<grin>, the JPL library doesn't have it, and I 
probably threw the issue away a few years ago)

Indeed.. and I'd say that most schools benefit by interested parents.  All 
to the better if they are math/science oriented, and if a sustaining 
program can be created.  It does happen.  It would be interesting to look 
at other successful programs and see what their origins were.  Athletic 
boosters have been around a long time, so that's not a good model, but 
perhaps a theater arts or music program that came into being?  Or even 
Science Fairs (which are out of fashion, these days).
