Task：School teachers used to be the source of information; however, some people argue that teachers are not as important as before because of the increasing variety of information sources. What is your opinion.
When it comes to the necessity of teachers in the current era, some people argue that they are less important because students have other sources of information, but I cannot agree with this opinion.
To begin with, knowledge of teachers is more authoritative. It is true that students could obtain knowledge from other sources, such as Internet. However, since everyone can post on websites and forums, it may be difficult for students to tell the difference between right and wrong when they encounter contradictory opinions. Thus, teachers are still necessary as a source of information since they have gained professional knowledge in advance.
In addition, teachers know how to teach students in a suitable way. Many students find it difficult when they begin to learn a new subject since they may never hear of it before. However, teachers, more often than not, will have an integrated plan of a subject and begin their teaching from some basic points to lower its difficulty for beginners. Therefore, following teachers who are potent to guide students to learn in a systematic way is more effective and efficient than other sources of information.
Furthermore, students can improve their practical skills with the help of teachers. For some subjects, such as chemistry and physics, students need to do some experiments in order to deepen the understanding of some phenomena. Without experienced teachers, students may face danger since they just know the process of experiments theoretically but do not have practical experience. For example, chemical explosions may happen if students wrongly put some materials together.
To sum up, teachers still function as a crucial source of information, considering their authoritative knowledge, systematic ways of teaching, and practical skills.
