With Chromebooks becoming popular in our classrooms, teachers now want to have students do exams (mainly essay writing) on them, super simple with Google Docs and Classroom. However they want to block Internet access, I managed to find a real clunky way of doing this so it's not the method I want to continue using.
My solution was in GAFE control panel: Create an OU and change user settings for that OU to blacklist all HTTP/s websites and make exceptions for google classroom and docs
Then for testing periods, I'd move the students in to that OU.
This did the trick except for the Docs "research" feature. It allowed students to login, go to Google Classroom, get the assignment, and type their essay. When done, I'd need to move student out of that OU.
I was hoping for a way to make the blacklist settings devices, rather than student, but that's not possible.
I tired public session kiosk modes and single app modes but Google Docs does not work in that setup.
I tried setting firewall settings for specific wi-fi SSIDs, and have an OU of chromebooks forced to connect to that SSID but that didn't seem to work either.
What are all of you doing?
