Someone else remarked on having "many wonderful teachers". I had very few. They were mostly mediocre (but nice people who meant well) or else mediocre (and jerks). The one I'd call, "most effective" or "best" was a young math teacher who stood in front the class, explained things very clearly and in all-business way, barely ever cracked a smile (but wasn't loud, intimidating, show-offy, of mean either), and didn't waste my time with foolish stuff that wasn't related to the subject at hand. He wasn't everybody's buddy, and he didn't do a song-and-dance act. He didn't waste a minute of class time. In fact, unlike a lot of other teachers, he did't take up the last ten minutes of class talking about the next homework assignment. It took him about 30 seconds to assign homework each day. At the other end of class-time, it took him about two minutes to shuffle whatever had to be shuffled on his desk, before he left his desk and began teaching the next thing.
I don't know how "wonderful" this individual was, but he was an excellent teacher.
I think what kids expect from teachers can depend on what they need from "outside adults", as compared to what they don't. I had two really good parents and came from a family where aunts and whatever grandparents (grandfathers in my case) were left offered plenty of support to the kids in the family. All I ever wanted from, expected of, teachers was that they do a good job teaching their subject and move things along enough that the class wasn't torture-by-boredom or else chaos. This guy did that.
