I actually want to incorporate blogs in my classroom due to the fact that it will encourage reading and reviewing of peer work. I find in my school, students often write things without rereading to make sure it makes sense. I wonder if having it posted to the internet would encourage the students to make sure their words are understood.
As a math teacher, I would love to incorporate blogs as a ticket out, or as a reflective homework assignment. We are always encouraging students to write out their thoughts even in such a number-based subject area. I think this will help students' connect the skills we learn to our school's themes each semester. Currently our school is focusing on "Global Awareness." What better way to understand this concept than to have them on the "world wide web" experiencing people around them and diverse and divergent thinking.
