Course content, always written on the white board prior to the student arrival should put an instructor into a certain mindset re:delivery.
I can identify with one of the other comments that the total coverage of the subject matter is essential, and add that yes, the manner in which an instructor does this is just as important. Conveyance via a lifeless monotone, listless nature won't capture the student's attention.BE VIBRANT! Additionally, the longer an instructor has taught the subject, the better the delivery. He/she can make adjustments to course reference the style; what works? what didn't work?
