This would have to be the greatest treasure that Microsoft Office has in its repertoire and yet so few people seem to use it! Using this piece of the Office Suite, you can capture video, sound files, text and copy directly from the web (and it arrives with a citation!) Best of all it can be password protected and you can sync it with other devices. It is available as an app for Apple or Android devices, so it can be accessed anywhere.
Other Office files can be embedded into it and then all can be displayed and accessed through Notebooks. It is the perfect tool for teachers, as students can have their Notebooks syncing into your OneNote so work can be accessed and feedback given at anytime! To find out more have a look here:
