SkieCan a teacher lock every student tablet in the class during a lecture?
Yes. A teacher with access to a class can lock all tablets in that group from the group view, and release them when the lecture ends. They only reach their own group. For a longer routine, a timetable window can do the same thing automatically at set periods.
The common classroom problem is simple. The teacher is explaining something and half the tablets are open to something else. In Skie the teacher opens the class group on the dashboard, which can be used on a phone or laptop, and locks the devices in that group. The tablets lock, and they come back when the teacher releases them.
Because roles are scoped, a teacher only sees and acts on their own group. They cannot lock another class or change the school's baseline policy. A branch head or school admin can do the same at a wider level when needed, for example for an assembly.
A manual lock suits unplanned moments. For routines, use schedules instead. A window has days, a start time, an end time and a list of allowed apps, and the first matching window wins. You could set the lecture periods to allow only the reading app and a calculator, and leave break time open to a wider list. The tablets switch on their own and no teacher has to remember.
If the tablet is offline when the lock is sent, it applies the next time the device syncs, and rules already stored on the tablet keep working without a connection.
A practical tip: agree a small set of expected behaviours with teachers first. Tell students that the lock is normal, and that it ends at the end of the period. A lock used fairly and predictably causes far fewer arguments than one that appears without warning.
