This isn't anything new, but it does have many examples from Stephen King's novella, "The Body"
This assignment invites students to pretend that the characters have phones and are tweeting throughout the story. It makes sure that students understand a characters emotions and perspective as well as the main event or theme of the chapter / story.
I use this as one of the chapter assignments, but you could use it to be done before the book is read, or after.
There are several different examples done by students you can view.
This was originally designed as an assignment for upper level EFL students in high school, but it could be used with any students using The Body (or with any literary story).
