Actually, it's quite simple: following the ideology de jour and
Teachers will teach what's mainstream ideology (I'm using "ideology" in
a strictly neutral sense here).
Pascal was popular because teachers felt that structured programming
should be taught to the masses, and you couldn't abuse goto in Pascal to
make a program unstructured.
Later, universities shifted more towards "economic usefulness". Which
made C (and, later, Java) much more interesting ideologically.
Teaching-relevant support means: readily available tools. I.e.
compilers, debuggers, editor support, and all of this with campus
licenses or open sourced.
I don't think that Haskell can compete on the ideological front right
now. That domain is firmly in the area of C/C++/Java. Erlang isn't
really winning here either, but it does have the advantage of being
connected to success stories from Ericsson.
To really compete, Haskell needs what people like to call
"industrial-strength": industrial-strength compilers,
industrial-strength libraries, industrial-strength IDEs. In other words,
seamless Eclipse and Visual Studio integration, heaps and heaps of
libraries, and bullet-proof compilers, all of this working right out of
the box. (I see that this all is being worked on.)
Teaching-relevant support is already in place, I think - there are
several open-source interpreters and compilers available, and Haskell
doesn't place an special requirements on editors, nor does it require a
specialized environment (the bane of Smalltalk and Lisp).
