How I Use It
Personally I use it to record and store anecdotal comments. They are immediately shared across all my devices. With the addition of the SKITCH app I can also add and annotate pictures of student work.
Students have been using it save and share links and web images. They can create shared groups for groupwork as well and use it in conjunction with DRIVE.
It worked better on our netbooks, and laptops than our iPads (but that is common to many of the apps I use).
This is a great app that I used outside of school on a very regular basis before thinking of how I could apply it to my class. I started by introducing it as an organisational tool and a personal curration tool. I have a feeling that I have only scratched the surface of what this app could do in the classroom for me. In terms of student use it seems that it is almost too big for them. Some students love it. My students who like specific directions and closed activities have a harder time with it.
