A Seventh Grader's PLE
A personal learning environment is a pretty new term, but it is essentially an aggregator for all the sites you might use to perform your necessary functions. For example, you might have your Facebook page there, websites you frequent, Google Docs and more all in one place. I use igoogle.com for mine. Above is another aggregator called Symbaloo.com which a 7th grader uses to demonstrate how she does her classwork. It is very much worth a minute to watch it.
