I visited another classroom this week. The basics of the activity involved students commenting on other students blog posts. I watched as the teacher answered questions all hour, moving frenetically around the room. She took 30 seconds to say to tell me that because the comments were being read by other students there were dozens more questions than the same less done on paper last year. We have been told as teachers that making our students have a more authentic audience will lead to better learning. The simple and great start is to make them read each others work. Technology, especially the laptops, make that so easy to do.
