An Instructor must "be prepared" to teach the class at all times. Use the required text book, following the order of the syllabus, and know the objective of the required topic is important also. The Instructor should also have enough time after being prepared to plan around how they are going to opperate in the class, as what you have plan to give an open forumat the beginning of each class and adding industry current specific events. I totally agree with what you write. Aron it is also good to analize the students action in the class that the Instructor have taught before,and the short fall. This will help the Instructor to be more prepared.
