We often knowingly teach false science. Such a practice conflicts with a prima facie pedagogical value placed on teaching only what is true. I argue that only a partial dissolution of the conflict is possible: the proper aim of instruction in science is not to provide an armory of facts about what things the world contains, how they interact, and so on, but rather to contribute to an understanding of how science as a human endeavor works and what "sorts" of facts about the world science aims to provide. Such an aim legislates for an increased prominence of history and philosophy in even secondary science education. (Contains 8 footnotes.)
