My approach to teaching rests upon four principles. First, students will excel if we offer a curriculum that challenges them. If we expect a lot from them, they will appreciate our confidence in them and perform well. Second, courses and curricula must be tailored to meet the intellectual, professional, and practical needs of students. Third, students can learn a great deal from each other in a learning environment that is conducive to the exchange of ideas and perspectives; if the classroom is structured as a marketplace of ideas, students will do a lot of shopping. And finally, I believe that teaching, research, and service are mutually beneficial; each should complement the others.
