I love this....who came up with it? I am going to share this with my colleagues. It is so powerful. Some instructors arestill doing it the old fashioned way of encouraging through embarrassment. In the the generation of student swe are working with, young or old this strategy does not work. The older individuals are so self-conscious that the strategy can be debilitating to them. And to the young, they simply do not recognize this mode of communication nor do they care for it. Both entities will simply quit and look for a school that treats them with dignity!
