Social Skills & Video Modeling

I spent the day at an autism conference in Crystal Lake. The speaker, Scott Bellini, who is the assistant director at the Indiana Resource Center for Autism at Indiana University presented on Building Social Relationships. Towards the end of the talk, he demonstrated the use of video modeling where you film, then edit the video so you have a new video of the child only engaging in the behaviors that are positive. I have used video modeling with surprising success in providing social skills training for a group of kids on the spectrum. What was surprising was not that it was successful, but how successful it was. What I saw, was supported with Research presented by Scott Bellini. The outcomes reported based on valid research methods were amazing. The fact that we know this works as well as it does only has me echoing Scott's same question; Why isn't everybody doing this?
