So are your pupils are already familiar with using Microsoft Word? Then why not consider using Microsoft Word Online available to all Glow users in Scottish schools as part of Microsoft Office 365. Word Online is available anytime, anywhere with online access so can be accessed at home or at school.
Word Online can be used to create document from the beginning (or you can upload an existing Word document from your computer to make it available to edit online thereafter). You can keep it private to you in your own OneDrive (the online cloud storage with massive capacity available to every Glow user in Scottish schools). Or you can, at any time, choose to make a Word Online document visible to other users of your choice – and you can choose whether to allow them to just be able to read it without being able to make changes, or you can give other users the access rights to be able to jointly edit the document with you.
Have a look at the Sway presentation here for a step-by-step guide for learners to create a Word document in Word Online in their OneDrive in Microsoft office 365 via Glow and to share this with other Glow users to be able to jointly edit the same document.
You can use this same principle of sharing a document in Word Online to have on-screen post-it notes as described and illustrated by Lynette Barker here
