I know many people talk about how great Whole Brain teaching is. I have seen many of the videos and they seem to work. But does it work really? I can just see my 1st graders being silly with it. I know that I took a class on classroom management and they talked about creating a calm environment and the teacher speaks in a calm low tone. When I watch these videos the teachers seem to be very vocal and that in return makes the kids feed off of that. I have never done WB teaching or seen anyone in real life use it. I only learned about it from this site. Are there any cons? Or is this really a great management system?
