It would be possible to teach straight modern biology without evolutionism thrown in. I think geology might be problematic, although I can see just teaching about present geological formations without attempting to explain how they developed, sort of the same way you would teach biology, or if you were going for a straight theological approach simply explain the Creation to modern development.
Great, but what do you do when your students start asking "how" and "why"? "God did it" only holds out for so long. What happens when a kid who does his homework asks you some question that contradicts what you've been teaching?
Maybe I should just call one of these college's professors. Anyone have an idea which one I should call?
