Nowadays, we can learn from computers and we can also learn from Human teachers. What do you think are the advantages and disadvantages of these two kinds of “teachers”?
Computers PK Human teachers
With the development of computer science, we make use of computers almost in every aspect of life, especially in education. We download materials, listen to lectures and even take exams on the computer. Some people predict that one day computers will take the place of human teachers. Is that true? It is true that computers bring us a lot of conveniences. For example, we can listen to a lecture without leaving home and can stop at any time we want. We can also take free courses on the Internet. But we have to admit that if we have some questions while we are listening to the on-line lecture, no one can help us clear up our doubts right away. Perhaps we can only send an e-mail and then wait for the reply for days or even for weeks. However, we don’t have to face such problems if we learn from human teachers in that they can answer our questions at once. They can adjust their teaching process according to how well we can follow them, that is, they can adapt their teaching methods to suit their students’ levels. However, to learn from human teachers, we will have to go to school everyday, and in doing so, we will have to spend a lot of time traveling to and fro schools, thus suffering from traffic jams and all the other kinds of inconveniences.
As a whole, both computer teachers and human teachers have their advantages and disadvantages in their own special and unique way. Therefore, I’m sure they will exist side by side in the future.
