Sure. Any subject you have to start off with the simple stuff, otherwise you'd never get anywhere. So in teaching students Physics we start with the simpler bits, such as Newton's laws. Then later we tell them that these need to be modified at high speeds (relativity) or at small scales (quantum mechanics). So, we could say that we teach them material that is ultimately "wrong" (Newtonian mechanics), but on the other hand Newtonian Mechanics is:Kim O'Hara wrote: I would like to add that this is pretty much true for any teacher trying to teach any bunch of willing adultsanything at all, whether it yoga or tennis or calligraphy: you have to start from where the students are at and introduce skills and concepts at the best rate they can absorb them.

Teaching something which iswrongis never a good idea, because you have to un-teach it later. That wastes a lot of the students' (and your) time and costs you credibility. But bypassing some of the stuff they are not ready for, so that they can move ahead with what theyareready for, is good practice. ...

1. A good enough approximation to design bridges, planes, and so on.

2. Without mastering that "wrong" theory, it would be very difficult to learn the better ones.
