To help my students delve into Ch. 15 and really analyze Kenny's behavior, I had them do a brief research assignment on Posttraumatic Stress Disorder. I gave them two trustworthy websites and they had to first define PTSD and then prove that either Kenny was or was not suffering from PTSD in Ch. 15. The students had a great time with it, and it really helped them analyze character behavior. Please note that I taught this lesson with ninth grade students and that it may not work with lower grade levels.
