Taking positions

In my experience, teenagers don’t like to take a position, especially on controversial subjects, because they are afraid the rest of the group will not agree with their opinions or sometimes simply because it is easier not to.

This is why it is a good idea to ask them to physically move to one or the other side of the classroom, depending on what they thing about a subject matter. The opportunity to move will give them a moment of time to make the final decision and at the same time offer a bit of stretching. Even if at first they seem reluctant, they later like the idea as it also gives a more visual representation of standpoints.
