As the Faculty Development Advocate at our higher education institution, I have seen time again the downfall of new instructors because they entered their class with minimal preparation and were sorely unprepared. Preparation helps promote confidence for instructors and is often half the battle to a successful class. Is there anything worse than entering a class without all the necessary materials, lesson mapped out, topic to be covered? I would imagine student would rapidly lose respect for teachers who enter the classroom this way. I will often map out my hours in class in 30 minute increments so my time is wisely spent and the students get what they paid for.
