Two wrongs don't make a right. I'd say it's more important to stop teaching pseudoscience in science classes than to use it as a justification for teaching pseudophilosophy in philosophy classes. And in general, novels should be taught in literature classes, not philosophy classes - although the example of L'Etranger suggests that there is room for crossover.
(Anyway, the majority of Rand's work takes the form of non-fictional essays. Her novels made her name, but it's clear she saw them only as means to an end.)
Actually, there is a good reason TO teach pseudo-science in science classes: to expose the student to literature which is not science. One of the most critical features that defines a person as a "scientist" is his healthy skepticism. This is very often NOT taught in science classes.
Since most pseudo-scientists have a genuine concern over some problem, and they have obviously acquired what little scientific exposure they did from their schooling, then I claim that if more science classes covered pseudo-science, explaining why it is not true science, then I predict a distinct drop in pseudo-science will result.
