The difference being that in Oceana, INGSOC forced every member of the Party to have a Telescreen in their room. If you so much as tried to turn it off, you were disappeared...
These morons are accepting their Telescreens voluntarily.
Actually in this case, the students were required to use the school provided notebooks, take them home, and in at least one case a student got in trouble for putting a sticky note over top of the camera bit.
