I feel that our personal learning networks are one of our greatest advantages. It gives us the opportunity to communicate with others in our field and access tools that will help us make our lessons more effective. I have accounts that I check on a regular basis such as Twitter, Gmail, and Blogger. I have created accounts for Symbaloo and Delicious. I also use Dropbox. There are a number of useful and helpful sites available for teachers to enhance their personal learning networks.
