Let your students see what you are saying by visualizing it. Talk with pictures. Have fun with magic illusion and transition to a key teaching point. Startle students occasionally with a provocative statement or question. Teach students, not subjects.
Teaching is like fishing.
Sometimes they bite and sometimes they don't. It depends a lot on the type of lure that you use. Lecture only 8-12 minutes before you involve students in their learning in some way. Create a safe environment in which students feel comfortable to express their ideas. Fill students souls with dreams and help them to make those dreams come true.
