Rapid development of technology provides convenience and freshness for many aspects of people’s life, including education. Nowadays, students become more reliable on computers for research and are often asked to hand in a perfect paper by schools. Others even have decided to give up the original way of learning and to obtain knowledge through online institutions. These changes in learning and teaching methords have aroused a special concern regarding the fading of teacher s’ giving lectures in classrooms.
Some people observe that compared with that of an original classroom, the role of teachers is beginning to drop because computers can help students study faster. For example, in the classroom, most of students’ intellectual capacities can not be activated, and thus some would be confined to a slow advance in their studies because of others' lower capacity of understanding. However, thanks to the new study mode, pupils could progress in their acquisition of knowledge at their own pace.
The presence of teachers, however, is essential for students because human interaction plays positive and significant roles which can hardly be replaced by the cold machines. Firstly, from teachers, students can gain more than mere knowledge in the textbooks. They can cultivate their interest in certain subjects and establish emotions with students and teachers. They can learn the importance of communication through working in a group and how to respect other students. Furthermore, it is necessary to have teachers in the learning process to learn students' deficiencies and help them solve their problems by repeating explanations, giving extra instructions or even suggesting a tutor. Hence, students can have a bigger chance of passing exams.
To conclude, although computers and the Internet do brings convenience and speed, the role of teachers in the learning process is still very important and it will continue to be in the future because machines cannot replace human interaction.
