I have a MacBook Pro that I use at both home and school. I carry it back and forth between work and home each day.
As I arrive in my classroom and set up my computer, I take a few minutes each day to reconfigure this machine to work on my school’s network.
It takes 18 clicks, 18 clicks of the mouse to change the settings on my machine from the open computing environment of home, to the filtered, proxy-servered world of school. I know that on a Mac I can set this up automatically based on location; but I haven’t.
Those 18 clicks of the mouse when I arrive at school, and then again when I return home in the evenings, serve each day to remind me about open vs. closed learning environments.
