The
"overhead projector" has long since been retired in favor of the
document camera/video projector combo.
It is easy to use and even if you
are not sure how to operate it, more than one kid in the classroom should be able to help
sort it out. The most common problem is selecting the DocCam as the source for
the projector.
Three years since they started
arriving in the classroom, even I can usually sort out any connectivity problems
and get it working. It is usually the first thing I do after reviewing the
lesson plan to see if I'm going to need it for the days lesson.
So, here I am in a 2nd
grade classroom on the first Monday after the Thanksgiving week with only
20mins before class and I'm in totally stumped trying to get the stupid thing
to work.
The
projector is on, the doc/cam is on, the cables are connected and nothing is
working. The video projector is "searching", without success, for an active display
source. The old standby reset solution of power off/on did not help. The tech-savvy
teacher next door couldn't get it to work either.
We made
do with the old-fashioned whiteboard and dry-erase markers for math lesson.
It
wasn't until after lunch that the school custodian suggested an answer -- mice!
It
seems that mice have recently developed a taste for plastic cable sheathing and
are gnawing on some of the computer cables in the ceiling and under the classroom
floors.
One
teacher even reported, with some irony, that she came in one morning to find her computer mouse cable chewed on, presumably, by one of its real world
cousins.
