The mode of class lecturing The age 14 to 18 is a prime period for children to acquire knowledge and obtain basic ability of life. How to educate high school students has always been a controversial topic. Some argue that teachers should focus on lecturing in order to establish a solid foundation of academics; while others believe that getting students involved in discussions is a more important role that a teacher should play. From my standpoint, discussing and communicating provide students with more profound benefit than solely listening to teachers and taking notes. My reasons can be listed as follows. Getting involved in discussions cultivate the ability to deal with opposite opinions. Views always vary from different individuals, no matter when it comes to study or life. It's of significance for students to learn how to evaluate conflicting ideas. For instance, we always compare various ideas in a conference to finalize an action plan for the society. Every proposal should be considered carefully so as to figure out the most effective and practical one. Practicing communication skills via discussions instructed by teachers will guarantee students an earlier and better ability to achieve optimum out of different opinions. Discussions in class are also beneficial for the cultivation of the critical spirit. The ability of independent thinking, known as the critical spirit, is very important for students. To some extent, discussions are like several debates combined together. The speaker must state his or her views clearly with specific examples; while dissenters bring forward exceptions or logical problems of the statement. Students are inspired by opinions from different perspectives, which help expand their horizons and improve their ways of thinking. Quite a few people hold the view that teachers should put their major energy on lecture and ask students to take notes so that students can have comprehensive understanding of the knowledge. Nevertheless, acquiring knowledge is not the only purpose of study. The ability to weigh different ideas and think independently, which can be obtained through discussions in class is more conducive for their entire life. In conclusion, guiding students to have discussions and exchange their own thoughts makes it possible for students to cultivate the critical spirit and the ability to tackle with different opinions, therefore, is a more advisable mode of class lecturing.
