But there's a lot of pseudoscience being taught today. Maybe Rand shouldn't be taught, but why isn't it? Because of the form of her output (novels)?
(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.)
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.
