Manipulative algebra programs for higher mathematics are useful, but for
learning stepwise processes, I'd seriously doubt the value.  In fact such a
program might be, as you suggest yourself, a deterrent to active thought.  So
far as being useful for the teacher, the teacher is supposedly already learned
in his/her profession, and really should not need such a device.  There are
already some VERY powerful symbolic algebra programs available, and they usually
need the effort of a team of expert mathematician/programmers.  It's a huge
undertaking, and if sucessful, of benefit usually to those who are already
fairly accomplished in the field.  That includes senior students.

It's one of those "good idea at the time" sort of things.  One possible use I
could think of, but barely, would be for a student to use it *after* having made
a reasonable perosnal attempt, and as a check to his work.  However, knowing the
general attitude of the majority, I'd suspect that you would be more correct in
your assumption that such a tool would be one for the lazy, who would then lose,
not having gained their rightful education through their own personal

I've already seen one such finished program, and had to discount it as being of
little additional value.  Sorry, I can't recall the name since it was some time
