Advocates of distance education give their arguments as follows. On the one hand, distance education makes it possible for people in remote areas to study subjects they are interested in. On the other hand, through distance education, people have a wider choice of teachers and courses, because they can hear the best courses of the best teachers in the country and even the world.
Just like "there are advantages and disadvantages", opponents believe that not all people have the opportunity to receive distance education because many people are poor. Besides, students can't get in touch with teachers, but interpersonal relationship is very important for their study.
As far as I'm concerned, we should develop distance education faster to benefit more students. At the same time, we can design some programs to help teachers and students contact each other.
