Share a Story - Change the World
I have collected representative results of studies of the effects of storytelling in education on my blog at -- https://mazgeenlegendary.wordpress.com/storytelling-in-education
It's a bit repetitive, but that only shows that all studies have found a positive correlation between storytelling and improvement in all subjects.
Richard has reactivated this discussion and I realized there's an excellent resource that has gone through a few websites, but is hosted among the National Storytelling Network's resources about Storytelling in Schools. It's by 2 members here at Professional Storytelling, Kate Dudding and Jackie Baldwin. There are quantitative studies, innovative projects, and much more.
