Teaching the controversy is a catch phrase that people should be aware of.  Firstly, it usually prefaces a false equivalence between two topics, for instance, evolution versus creationism.  Evolution is a explanatory theory supported by a large body of factual evidence.  Creationism, on the other hand, is a mythology made up by ignorant people and handed down through the centuries to keep the feckless from asking too many questions.  The positions are most certainly not equivalent in any sense of the word an thus, are not comparable, lest you wish in Physics class to postulate that invisible elves are responsible for making pool balls move a the precise angles they do when struck.
