The Education Game

Evoke

Paul Allison, an English teacher at East-West School of International Studies in New York, has been playing  EVOKE right alongside his students. He's one of several teachers from the New York Writing Project who decided to experiment with the game as a springboard for digital literacy.

Here's how it works: Each week, a new chapter from a graphic novel introduces players to a different challenge from the not-so-distant future. These "missions" range from food scarcity to human trafficking. Players respond -- and earn points -- by posting blogs, videos, or photos that convey their proposed solutions or reactions. They also comment on other players' postings, sparking dialogue, collaboration, and critical thinking.
