Have a specific goal or set of objectives for each class. Come with well organized introductory material, questions to ask, examples and analogies already prepared, and with your answers to possible student questions already thought through. The Center for Teaching and Learning can arrange for someone to observe your practice and give feedback. Even better, the session can be videotaped and you can evaluate the presentation yourself. The fastest way to become successful at teaching is to get feedback on your approach right from the beginning.
Teaching is more than just giving information.
It's motivating people, getting them interested, giving them new concepts and approaches, helping them to learn better. Read and think about models of how people learn. Observe yourself and others as learners. Become acquainted with these offices which may enrich your teaching or help support your students at critical times.
