battery check-out (by bar code) in library. Must be returned by the end of each day. (huh!)
3 power adapters in heavy use classrooms
supplemental batteries to rotate in classes where there is unusually heavy use i.e. special projects.
It seems to me that any tool that is over or mis-used will lose its' value.

Subject: Re: Battery "best practices" in an 1:1 environment
Thanks for the very helpful input.
I find it fascinating that an apparent "technical" issue like charging a
battery is perhaps more complex and linked to "teachable moments". But I
suppose all school situations should be considered opportunities to teach
and learn.
Alex,
Getting back to a practical matter, are you saying that it's basically a
"free for all" with regard to battery charging at Whitfield or do you have
a policy that is monitored?
Thanks,
Dave
