I have at least 3 or 4 former instructors who made a huge impact on my own teaching style. One, whom I remember very clearly, I remember for the wrong reasons. Although it was clear he enjoyed the subject matter, he never moved from behind the podium. Now, whenever I walk into a classroom, the first thing I do is take the lectern and move it to the side of the room. If I have passion, the students should see it.
Another I remember because he made us recite lines of plays at the beginning of class, as a group and as individuals. I hated those moments. It scared me to death. But, I still remember the lines! And I try to incorporate that challenging aspect of recitation, only without the fear. How? Well, I always go first!
