I've used this in conjuntion with a tense clip/piece of writing. Students have to think about HOW tension is built and add ideas to the wall. Matt Posner: a quick handout about authors create tension in a story. ...Glad to know that's how I do it. I just kind of internalized the process... A minor, usable resource if teaching a suspenseful story, such as (I suggest) Jacobs' The Monkey's Paw.
