1. I have not used this option, but someone shared this so you could set the max to the amount of students in your classroom.
/setmaxplayers is also an option.
2. We use all of the above tips, but I have also created a world where all players begin in a holding room of deny blocks surrounded by border blocks, then I have the world operator (owner) teleport authorized players to the build location for especially problematic schools. The world is currently syncing to my one drive, and I will share it after if you are interested.
Here is the world - all the world "owner" has to do is use /tp to move authorized students into any location not from 5, 4, 4 to -5, 4, -5 - I usually use 10, 4, 10 as my point to send them to. https://mailcherokeek12ga-my.sharepoint.com/:u:/g/personal/9927902_cherokeek12_net/ERtaLs8XljZMtcU1jLCogZkBckPo5tIRvX2sCD9bQcUzZQ?e=QhiYZs

3. It is important that ALL teachers teach Digital Citizenship and have consequences for students that are doing this. We tell our students that they will have an alternate assignment and we inform parents. Even if they are in another class, we inform that teacher and the child is removed from the device and given an alternative assignment.
4. I turn off LAN and tell students which IP Address to enter rather than leaving it so anyone can join. We’ve had...interesting experiences to say the least.
