Learn how not to read your lectures. At its best, lecturing resembles a natural, spontaneous conversation between instructor and student, with each student feeling as though the instructor is speaking to an audience of one. If you read your lectures, however, there will be no dialogue and the lecture will seem formal, stilted, and distant. Reading from notes also reduces your opportunities to engage your class in conversation and prevents you from maintaining eye contact. Prepare yourself emotionally for class.
Some faculty play rousing music before lecturing.
Others set aside fifteen or thirty minutes of solitude to review their notes. Still others walk through an empty classroom gathering their thoughts. Try to identify for yourself an activity that gives you the energy and focus you need to speak enthusiastically and confidently. Or walk in the door with students and engage them in conversation. Using your voice informally before you begin to lecture helps keep your tone conversational.
