Hi, Just tried to have a look but the link isn't working for me?

Thanks for sharing.
I think this fits with the RAT framework too. While it can be a Replacement of pencil and paper with the technology,

There is Amplification through sustainability- less paper being used, efficiency- in both the production as students are able to take photos and upload directly to the app, and in marking as the teacher is able to monitor student's progress, provide feedback at any time- students could be working on their book at home with the teacher providing feedback.

This app allows for Transformation through the numerous possibilities available to allow students to be creative, students who don't feel they are overly creative or artistic (like myself) don't have to rely purely on their drawing ability to create a story, they can also personalise stories with pictures of their own family or home environment. Student's can share the story with family and friends while the teacher still has access to mark and retain a copy. there is also the great advantage of student's not losing a work in progress! no breakfast or drink spilled all over a final copy ready to hand in.

Thanks again for sharing, I am blown away by what is available out there to use within the classroom!! up until the beginning of this semester I would have thought I was doing well to be using word or powerpoint in the early primary classroom!!
