Earlier today on Twitter, Alfie Kohn asked which signs directed at students were bothersome. Tim Stahmer followed up by commenting that he was bothered by signs that told kids to put away their mobile devices as though they had no instructional value. The exchange reminded me of a short blog post I meant to write but forgot about. Here it is now…

I was at a workshop for science teachers and they were doing some problem solving activities that required some basic math that they could have done by hand. However, most of them chose to use a calculator. Want to guess where those calculators were located? On their mobile devices.

Remind me: what’s the definition of irony?
