How do you teach Poetry?

I love poetry, but I don’t think I’ve ever had a class with a good poetry teacher. An infrmal survey around the store found this to be common, meaning that the only person who had not had a bad poetry teacher had never had a class about poetry.

Have any of you had good poetry teachers? How did they do it?
Do any of you teach poetry? How?

I literally would not care to correct your English.

Dr. BearHey, all my Grammar Maven friends!
Under what circumstances is it acceptable to correct someone’s language?

By this, I mean grammar, syntax, misunderstood or misused vocabulary, mispronunciations, pronouncing silent letters, words inappropriate to polite society, etc.

If it is a proper occasion, how ought one do so?
