Scientists who believe in a deity are not necessarily bumping into contradictions to their faith. Plenty consider theistic evolution to be a possibility. A deity actually makes a lot of the problems with our current theories much easier. It is actually possible to analyze all that can be observed and still be left with questions, and reserve the possibility that a deity is involved. You don't have to believe that, and I'm actually all for science education based on questioning and reasoning rather than forcing dogma down students' throats, but you shouldn't just assume that all creationists reason in the same ways and blatantly claim none of them advance scientific knowledge.
