I must apologize for sitting on this challenge for some time. I did have the pleasure of actually doing this with a digital video camera in the classroom. Once the students got past the Hawthorne effect in recording during my lesson, they were actually productive.
On the following day I allow the students to view the video. Next, I had them to write a reflection on their experience seeing themselves in action learning. Unfortunately due to the restrictions of my district (and the lack of time of my behalf) to have students to sign photo release forms, I cannot post the video.
However, I will try this again for it is good for students to see themselves in a form of visual metacognition (wow, did I coin a new term for this activity)!
