What are the good parts or side effects of online learning?

Think about it. How is having a teacher better than a website? What is the disadvantage of a teacher?

One side effect of online learning is that people get lazy and just copy work and don't learn anything. However if people research information properly and are keen to learn then the wealth of information on the internet becomes very valuable. A teacher may be better to ask questions and get immediate responses and explain parts you don't understand, however maybe you are afraid to ask the teacher questions or you are in a big class and the teacher doesn't have enough time, on the internet you can be anonymous and ask any question you like without being embarrassed...
