Three Ring is a new free service offering free Android and iPhone apps for digitizing and organizing student work. Using the app teachers can take a picture of a student's work and upload it to a free Three Ring account. Three Ring offers teachers a lot of organizational flexibility. You could organize artifacts by student name, class, date, or just about any other tagging system that works for you.
A short video overview of Three Ring is embedded below.
Applications for Education
Three Ring could be a great way to collect hand-written work without actually collecting pieces of paper. Just go around the room snapping images of your students' work. You can add notes to each image before and after the upload so it is possible to grade work using the notes field next to each image.
