Support Groups

Watching the video on how effective support groups are, and is there a better way was interesting to me. I did not think that putting people in a classroom setting and educating them on it would have more of an affect than people talking. I understand it educates them on what is going on and what is going to happen, so they can see their growth and where they are. Would this work for AA? I know it is a support group, but the use of the drug alcohol and its effects are widely known, would the classroom setting help the members in AA out? I am wondering if the results are just on subjects that people do not know much about. I believe that is the case. I think people are uncomfortable because they do not know what is going to happen. In the class room setting they can find out and really understand what is happening to their body.
