Blogging can definitely have a positive place in the classroom. By blogging, students may feel less intimidated by writing or sharing their opinions. Many teachers have their students keep a daily journal or diary to turn in-- classroom blogging is a modern update of this. However, classroom blogging must be used with caution. It is important to first teach the students about internet safety. It would also be a good idea to check with the principal for permission. If I had a classroom blog, I would use it as a place to share quality links and information with my students. I would also begin discussions with them about various composers or pieces we are playing in class, so that they could talk about it in a safe place. Some students have trouble speaking up in class, but online, they may not feel so shy.
