This is an invasion of my privacy
This thing sucks and the teacher just makes it worse
NON-PRIV DELETE THIS SCHOOL THING
It is spying, why can we not do our own stuff, I can't uninstall it and it is just stupid.
is it a stupid idea
Censorship is unconstitutional.
Why can't a teacher control his or her classroom, they should be fired. NO LANSCHOOL
Its awful
spyware
Okay, there's a million reviews, but here's what I'll say. Initially, this seems like a good idea. The teachers can monitor you and make sure you are on task. But, that's the issue. They can monitor you. Technically that's actually invading privacy. Sure, it's a school machine, and you're not likely to look up the same stuff as you would at home, but there are certain things you need to look up, but can't because they block websites through this app. And, consider that they can READ YOUR KEY STROKES! My password has not been secure in a long time. I know that not every teacher is going to steal passwords, but there's still that one teacher who might. This is a very insecure app as well. While you can control the screens of students, hackers can too. So they can hack into the teachers computer and control the screens. Who knows what they'll put up. Another thing is that not all of the teachers use it. At my school, ONE teacher uses this. NO ONE ELSE USES THIS! Sure, this could be useful, but consider the points I mentioned and make your own judgement.
