Teacher attention getting device for the computer lab
Good morning all,
I am looking for ideas on how to implement some kind of attention getting device for students to use instead of raising their hands...
I run a small school network at an international school in Armenia (around 70 computers with associated peripheral devices) and also teach the technology classes. I find myself constantly running back and forth in my lab, bouncing from one raised hand to the next and have found over the years, and not surprisingly, kids don't sit very patiently with their hands in the air for very long. My idea is to create some kind of device to place on top of their computers (the towers sit on top of the desks, next to the monitors) that they can use to signal that they need assistance, but that does not also prevent them from continuing to work, as keeping your hand in the air tends to do.
Something as simple as a flag they can place on top of the tower, or a small light bulb (maybe LED or USB powered ...) with an on/off switch, would accomplish the job, but I was hoping that somebody would have a more interesting suggestion.
1.) Dirt cheap and/or able to be built by a weekend warrior type of handy-man (me!)
2.) Materials must be very common due to the fact that I have a hard time purchasing goods from the US or UK (remember, I am in an international school) so everything must be available locally.
I look forward to seeing what the collective minds of edugeek can come up with...
The fraility of the human mind...
Sorta like a mid-tech (LED's don't count as high-tech... right) dunce caps?
We could incorporate a NIA game controller into the headband of each one to read the thoughts of the students and light different LED's depending on the thoughts.
All clear = green
problems = red
thinking about plagiarizing = amber
pr0n = white?
Oh the fun we could have! ;)
