How about a teacher you have to constantly look at, except when you're solving a notebook? I imagine there to be an open map, like you can explore the whole thing before you even collect the first notebook, and once this teacher is after you, you have to walk the whole thing backwards. Also, it would be cool if after you solved a notebook, the teacher is very close to you, staring at you, but he/she is giving you some time to escape and if you stand there for too long, it's game over.

Maybe in final chase teacher doesn‘t give a damn f*** anymore, if you look at him or not and we come back to the good old running away as fast as you possibly can part. As for the doors, maybe later it‘s possible to open them, even if you‘re not directly looking at them. Or maybe on a map with a teacher like that, there will be no doors at all.
Edit: And when you solved a notebook, you have about 5 to 10 seconds time, before teacher attacks you. For that time, he/she could be disabled, so he/she doesn’t attack you even if you‘re not looking at them.
