Hi Bryon:
I think a prepared teacher has taken time, thought, effort, and planning, and organized a thorough lesson with all needed resources, media, and teaching aids. The class runs smoothly, transitionaing from topic to topic, with students confident in the teachers abilites and comfortable asking questions.
This doesn't happen automatically, but is preceded with care and preparation by the teacher. I do agree that students are likely to be more respectful (because we are respecting their time and effort by good preparation).
Regards, Barry
