Wilbert J. McKeachie quotes:

The best answer to the question, 'What is the most effective method of teaching?' is that it depends on the goal, the student, the content, and the teacher. But the next best answer is, 'Students teaching other students.'

Professors known as outstanding lecturers do two things; they use a simple plan and many examples.

What could be more interesting to students than their own behavior and that of others?
