I always recommend that teachers rearrange their classroom so that all of the students are facing one direction which makes it easier for the teacher to walk around and monitor students progress. By arranging your class stategically, you can scan the room easily and you will be able to see who is on task, who needs assistance and who is completely lost.
Also remember to try and assign the students the same laptop from the same laptop cart as much as possible. This will help with the time needed to sync the computers.
Finally, please remind students to keep their desktop clean and uncluttered and try to get them into the habit of keeping folders of their work in their document folder. Things take longer to sync if they are scattered all over the desktop!
