Drama in classrooms

"A third general function stems from the fact that dramatic work unfolds in time: it is about living through experience" (52). I don't know how many times I've had it pounded into my head that a person's culture is the sum of their experiences. I think using kinestheic learning for students could be an opprotunity to use drama for interpretation and reflection. I know somethings I've learned throughout life, I've had to learn by doing (simply impossible to learn by reading or watching, for example: welding). But with drama, I think a teacher will always run into the problem of students not wanting to act in front of one another.  Or, futher, you know that classmate who hates public speaking or presenting to the class? To them, this would be like running naked through the quad. I understand the value in using drama in classrooms for multiple purposes but as educators, we'll have to be sensitive to some students' fears- what is pushing them, and what is pushing them too far?
