Here's a report  concerning a small study of 13-year-old schoolchildren suggesting they learned significantly more when they were banned from raising their hands in class.  Instead, every child had to write the answer to the teacher's question on a whiteboard and raise it at the same time.  Interestingly, this method helped not only the shy students but the bold ones who would otherwise dominate the classroom discussion.   What applications might this study have for the law school classroom?  Does it validate a random call system?  Does it validate use of the TWEN instapoll?
