I am hearing nothing of what should be taught. Please tell me, what model of the atom should be taught at JHS? At High School?
Perhaps you have forgotten that I prefer to limit what is taught before college.
Since it is not my field, I will bow to others on the thread if they have suggestions.
Either none or the most current model believed accurate. They don't necessarily have to get into orbit mechanics and how they all get shaped, it's enough to give a general overview that the orbits are complex and involve every part of the atom. No lying to students, we know atoms don't follow some goofy celular structure with a nucleus and simple rings of electrons around it, there's no reason to "teach" what we know isn't the truth. Simplify by omission, not substitution.
