Hi Rich: It's true. Prepared teachers who have taken the time and effort to prepare seem to have many more classes that run smoothy, seamlessly, even with interruptions or student questions. When we are prepared, we are better able to deliver our lessons with a minimum amount of interference (such as shuffling for papers, looking for handouts, leaving to get something like copies or equipment, etc.). And students notice. We can be the most knowledgeable person about a topic, but appearing in class unprepared can quickly destroy that impression of competency simply by not being fully prepared or organized.
