The web page above is another blog I found, and I believe that it explains nicely how blods SHOULD be used!

This blog is explaining how you should you blogs in education. I believe that the 4 points made in this blog are good things to go by. I am a student and I just starting using blog this year, so I am new to it. But, I do believe that blogging is a good idea to incorporate into education and the learning environment. As they said, use blogs for what they are good for, when they are necessary, or seem useful. If you are using blogs in education, you are not going to have to use them for every lesson, but I do believe that it will be good to incorporate blogs into a lesson every once in a while.
