With the rapid development of science and technology in modem times, an increasing number of people prefer studying online to attending school. What will happen if e-learning prevails and even replaces classroom learning?
For one thing, more people can access high-quality courses globally, such as Harvard free online courses. Therefore, even rural people will also get access to abundant and updated knowledge. For another, people can decide when and where they take the online courses much more freely. Thus they will no longer be bothered by problems like transportation and accommodation. As a result, learning cost will be so largely decreased that people can afford to apply for more courses they are interested in.
      However, for people who have bad self-discipline and learning habits, it is difficult to commit themselves to study. They will fall behind and actually learn little since nobody supervises them. What's worse, e-learning can't offer human interaction in real life. It is due to the lack of face-to-face interaction with teachers and classmates that people will feel isolated and gradually lose basic social skills.
     To sum up, that more people turn to e-learning will have both advantages and disadvantages. In my opinion, e-learning should be seen as a complement but not a replacement of traditional classes.
