1) A lot of my students have never visited outside of buffalo and have little to no knowledge about places outside the city. I could have the kids look up different cities, states or even countries and blog with people to learn more about these "far away" places. I believe this might spark some interest into looking outside their particular block or street that they live on. Sometimes all it takes is a little information about the seemingly impossible to suddenly make it possible.

2) Blogging could be used as a tool to teach positive interaction skills. My students all lack a degree of positive interaction skills and blogs could begin to teach them this. My students would be able to practice social communication without the added stress of actual person to person contact. My students would be allowed to blog about anything appropriate, from sports to music.
3) I would also use blogging for my own reflective purposes. It is important to reflect on each day as an educator and blogging could be a good way to seek constructive critisicm online about my teaching. Hearing other people's angles on situations and lesson planning always helps me reflect and I am sure blogging would be a very good tool for me to use.
