>> I had a theater class in school that regularly included improv exercises like described. In 11 years of it (K-10 or so), I don't think it ever went well.
My anecdote: theater/drama classes in middle and early high school don't count. You're mixed in with a bunch of teenagers who are only taking the class because either a) it's a mandatory class for all students; or b) more than half the class elected to take the class because it's "easy credit". When many/most of the students in a class aren't there because they actually want to explore the art, it ruins the entire dynamic. The same loudmouth bullies who cause trouble elsewhere in the school have an open season on the shy students; every step a socially awkward student tries to take to "open up" simply provides the bullies with more information they need to target the vulnerable.
Every participant must be present because they have a genuine interest to work with their teammates. Acceptance and cooperation are necessary in order to peel back social fear, and that means finding a group of like-minded people who show up to explore themselves and others around them.
