Sorry about the missing reference. I was thinking of (a) classroom clickers, (b) poll everywhere, which as you point out is limited to polls, and (c) UW CP&#x27;s student feature, which allows more interactivity but requires students to install the UW CP client on a laptop or tablet.<p>Big picture, I&#x27;m sure you are right that there is a lot of unexplored&#x2F;unexploited classroom tech that could leverage smartphones and sms for better collaborative and interactive work.<p>Incidentally, if you are looking for powerpoint export, the best way I found was to basically to export each slide as an image, including every animation step. Pathetic, slow, but mostly reliable.
