Blogs - Feelings, Emotions and Thoughts

Hi All,
Blogs....what are they? Why are they useful? How could they be used in a classroom learning environment?
The word Blog comes from the term web blog. They are used as a website or part of a website. Anyone can create a blog about anything they want. The issue with blogs is that they are open to interpretation and also are not academically resourced because they are written by anyone about anything.
Blogs could be used in the classroom learning environment for a variety of reasons. The learners could use blogs to reflect on their learning experiences and also to network with others to clarify issues and discuss feelings. The issue that was brought to my attention is that you can post information up at a wrong time when you have fresh emotions and opinions that could be displayed, and inturn have a detrimental effect looking back on thoughts, feelings and emotions at the time they were posted.
I am sure that I will have more to say once I have blogged a little more and networked with other bloggers.
Until next time,
Amy
