How I Use It
I've used storybird as a "story starter" with students. Having students look at a picture and begin orally telling the story of what the picture represents has been a powerful way to work with reluctant writers. We then transfer the oral version to the written page to create an original story. This process has been fantastic in helping young writers begin to work through the writing process in a nonthreatening way.
My overall opinion of storybird is that it works great for a limited purpose - helping stimulate ideas for writing. I'd like to see the option of creating original artwork to add to stories. I also think it would be helpful to have the ability to collaborate on a written work to allow students to co-create stories with each other, especially across geographic boundaries.
