Why Students need to blog ??

A students responsibility is to study, but when we blog, it's like playing, because you can write about anything on the blog no one care about what you write, even if you are write about the sports, it is learning something, but you might think that you are having fun with blog, you forget that you are learning. Then you are going to get a lot of knowledge.
For some reasons we can't explain something about profession terms, however if you use a blog you can put media in here and show program, so you can explain much better and a audience will get what you mean easily.
Most students are think that study is really boaring, like paper test, and we need to erase, write ... boaring but if you use a blog you can correct them easily like just delete everything with one keybord, so it's more confidence and a students study with a computer at first time so some students think "wow this is really funny !" so a students can study really hard as possible as they can.
