From POSSIBLE WORLDS about page:
Electronic games have an ability to immerse kids in new roles and worlds different from their own. We see this as a learning opportunity to make visible what is distinct about the world we live in through games integrated into school curricula. In particular, we want to help students disentangle misconceptions they bring to the classroom from the concepts and content they learn in the classroom, particularly in the sciences.
This research builds on the groundbreaking work of Jerome Bruner, who argued in his book book, “Actual Minds, Possible Worlds,” that narrative is central to learning. Storytelling help us “climb into” other ways of looking at the world, which allows us to see the particularities of our world more clearly.
