This suggestion really makes a lot of sense -- and it's an important point that we need to keep ed tech in perspective. It's tempting to go as big and grand as tech will allow -- who doesn't want to fulfill the promise of technology as much as possible? -- but sometimes the best immediate uses are 'smaller' and more practical.
I quite like this idea from one of my students. Do comment if you have a few minutes to spare ;)
