Although we can easily acquire knowledge from modern media like television and internet,I think it is not enough to prove that the teachers will lose their position in the future. Indeed,people can absorb a lot of knowledges from television and example ,some students now can watch many teaching videos on television and internet and they do not need to get these knowledge from modern software can even help students to make a suitable study is obvious that students do not need to listen to the fixed content in the classroom. However,are all students have the chance to get the knowledge that they want from television and internet?Many poor students cannot afford the cost of television or internet and some elders do not know how to use these various of knowledge from teacher is the best way for learning needs time to make the student cannot learn the new course if the courseware has not completed by the teacher. Even if television and internet can meet some needs of students but they cannot completely perform the effects of the fact, children also need to learn the method of communication and how to become a good this aspect,teachers play an important role during the learning computer cannot completely achieve the teaching goal. To sum up, modern technologies can replace some of teachers' job. but considering other important parts in education, I do not believe this development can make teachers useless in the future.
