Not just students... I've worked in a college before but it tends to be any shared equipment in any shared environment, simple reason is because it's not theirs,they don't care.
People tend to look after equipment if they think it's theirs and are responsible for it.
I'm was lucky and in the position where I wasn't responsible for the day to day running of desktops but I was at a site sorting out a server where they was getting ofsted monitored and one of the lectures was moaning that her adaptor was'nt working, so I popped in to take a look. Well it turned out that her adaptor wasn't working because she never brought it with her, so I simply told her to get it... bearing in mine she knew she was getting monitored, she basically tried demanding that I should get a spare one for her. Long story short, she went and got her own adaptor. Lol
I was asked to go to the room again because another lecturer couldn't get the smart board and PC working and again they was being monitored. I was like, it was working 30 min ago as I saw it in working whilst I was in the room.. Popped up to find that the previous lecturer had plugged all the cables to get her laptop working with the smart board and cba to fit them all back in as she found it. Bearing in mind that my colleagues went in over the weekend to make sure every PC was working, updated and tided up... But the same applies for every shared environment with chairs hanging out, rubbish everywhere etc.. People really don't give a ****.
