PicLits aims to provide inspiration for writing short stories. PicLits tries to reach this goal by providing users with images upon which they can build their writing. To get writers started, PicLits provides a list of words which can be dragged and dropped into sentence form. If you don't want to use or don't need a word list, you can select the "freestyle" option to begin free-form writing.
Applications for Education
The idea of PicLits is not to write a full story within the images, but rather to use the images as the inspiration for longer pieces. In that regard PicLits could be a good source of inspiration for the reluctant writers in your classroom.
