【正确答案】Recently, there is a heated debate over the pros and cons of lectures and discussions as two classroom teaching approaches. Some people hold that lectures enable students to learn more quickly and effectively. While others prefer discussions thinking they can help students learn more devotedly and creatively. Those who favor the former claim that lectures are more efficient for teachers to impart their knowledge to students over years of study and research. However others argue that in lectures, the teachers usually dominate the class and the students are confined to give full play to their imaginations and creative thoughts. But through the interactive activities involved in discussions, students will have more opportunities to air their views and foster their abilities to analyze problems independently. In my opinion, just as a coin has two sides, each method has both its advantages and disadvantages. Generally, lectures are preferable to discussions in science subjects, and just the opposite in humanity classes. So, different teaching approaches should be adopted to serve different subjects and different goals.
