I have had the privelege to teach in many areas-twenty years to this date- from kindergarten to the adults I teach now. A teacher must be prepared to deliver the content. If this isn't being done, then how is the student expected to gain the knowledge the instructor has to offer. To me teaching is a privelege, because the students have put their trust in me doing my job. they will listen to every word a teacher has to say and believe it for the most part. Thus an instructro must always be prepared to deliver.
