The idea of group evaluation is often as terrifying as a public speech, but both are beneficial. An idea for using this mehtod is to teach a technique or a part of a form or something of that nature. At the end of the class, have you and the class go to the front of the room. Have a student (volunteer or otherwise) go the center of the classroom and run through their form. Allow the other students to criticize the form (nicely, please) and then you can add corrections or clarify or correct what the other students have said.

The purpose is to get the students to look for problems and look for good things. At the same time, the performer will have to go through a public demonstration where the eyes are all focused on him / her. By having the students look for errors and good points they will be making mental notes themselves on things they should not do or things they should do. As as the performer, they can fix their mistake right away or make a mental note for future reference. For the less advanced students, the quick fix is best.

What this also teaches is an eye for motion. The students get practice by doing their technique / form and get a greater knowledge of their art and get sharper eyes by watching their peers. At the same time, advanced students will pick up more motion principles and get an understanding of how the body moves due to how their peers are moving. Evaluation is just as important a part in the learning process.
