It is the responsibility of the teacher to actively involve his or her students in the learning process. The most important thing he or she should do is to avoid giving clear, concise, organized lectures. If the presentation of a lesson is too easy to follow, most of the class will not need to learn the new material on their own. They will have a certain degree of confidence in their new knowledge, and this will tend to stifle their intellectual pursuits. If, on the other hand, the lecture is vague, rambling and disorganized, the students will leave with their heads full of questions. In fact, they will be so filled with curiosity that they will try to expand their knowledge on their own. There are many ways to present a thought provoking lecture. One of the easiest techniques to use is a foreign accent. If the accent is thick enough, even a well organized lecture will produce expressions of intellectual wonder among the students. Effective accents can be acquired in Alabama, China, India, Latin America, New York City, Germany, or any foreign country.
