IMO, the simple approach is dangerous. Saying here is the theory have at it is fine if you want to teach someone how to design transistors, but the point is not that QM is correct it's just the best approximation yet and in no way the 'holy word' on how the universe operates. The single most important thing to teach science students is to discard existing theory's when reality does not support them and to require any new theory to also be supported by the body of existing experimental evidence.
Definitely. However, it also happens to be the approach used since kindergarten up to high school, and in most universities. Whatever the field, as far as I know, students learn real science only when they start their PhD. Sometimes even later.
I would love to see a real science course, where students come up with theories and discard them, again and again, until they come up with something probably correct (or not). That would teach them to accept being wrong (I hope). Today, it's hard to do for anything but open questions, which tend to be pretty difficult.
