A blog about blogging
One of the things that I could use a blog for is to keep up with other teachers and get feedback on various lesson plans etc. This could also be done to stay connected to teachers in my grade level at my school, providing that all of us are computer saavy and that there is technology in the school.
Another way I can use blogs is to let the parents of my class what the class has been up to. What happened during the day, the vocabulary words of the week (I want to teach kindergarten, so homework will be of the minimum) could be put up. I could also use this to provide feedback to those parents who have access to a computer throughout the day. The only problem with this, is that I don't want to make parents feel like they have to have a computer in order to communicate with me.
Finally, I could use blogs to let the children in my class communicate with other students around the world. I could use it as a way for them to use the vocabulary for the week, as well as become more computer literate at a young age.
