EDU 652...Blogging as a Learning Tool

When researching for this weeks assignment I came across this Blog from Element K.  Basically it is a blog about e-learning.  From what I gather, they find various e-learning sites and then introduce and comment on them.  It does not appear that postings take place with any regularity; however, the postings that I read were relevant and full of information and links leading to other sites and blogs.  I probably spent more time examining the blog than I should have (I kept clicking the links and reading the other blogs) but it was sort of addicting due to all the information. 
Blogs have the potential to redefine learning as we know it.  Learners could be introduced to a whole new world of open discussions and thoughts.  However, I think it is very important for learners to enter the world of blogging cautiously.  Many blogs tend to be based on personal thoughts and biases.  Many times a blog will not even include a pertinent link, it will pretty much consist of one person's rant without any facts to back up the opinion.  I think links to facts is one of the most important factors in blogging.  Whether or not you agree or disagree with the cited article is probably less important than getting the reader to at least see the article and to begin to form their own ideas and opinions.  As learners it is up to us to be critical, as instructors it is up to us to make sure learners are taught to question opinion.
