Manager in my part time job
Every time she needs to set up the interactive whiteboard* when I'm doing exam preparation with kids in a classroom that has no old type whiteboard she faffs around for 10 minutes to get it working.
A couple of weeks back it lost connection for some reason. So I looked at the laminated sheet on the desk next to the teacher PC. Followed the instructions- took 30 seconds to get it connected again. Unusually these instructions are clear, simple and precise
*We occasional staff aren't given a log-in. Which is far enough to be honest- that's the only room we need it.
