Many students have difficulty understanding what "provoking" is and identifying when they do it. I encourage you to take time discussing what "provoke" means, maybe even using a word web, before using this activity.
This is an outline for a student to create 2 skits: one where he is being provoked and one where he is provoking others. The student needs to include himself in both scenes and create lifelike situations. Then have the students act it out in front of the group. I've also found that they enjoy drawing a "set" on the whiteboard, which helps them clearly picture this happening in a relevant environment.
This helps students understand that everybody provokes and is provoked, identify what they do that might provoke others, and realize that they can reduce social problems by not provoking others.
