Tech in class?
Well, Tech is a good way to connect but can distract people from doing the required activities.
Class Tech
Make an android launcher that only has the necessary apps, (eg. Notes (Memo), Video Call).
Make sure to make a secret button that lifts the launcher, followed by a prompt asking for a pin.
Make sure to disable features like the App Switcher, Power Off and Drag-Down Menu.
Kid Browser
Make a web browser where you can't put a URL into the browser and can only visit the sites set by the teacher.
Make sure it works and is up-to-date.
What do I use?
Any good android device, doesn't have to be expensive.
There are no good android devices but ok
