Too Poor for Clickers?

Try phones.

Another talk from the conference was a report from Pat Pukkila on her experimentation with the web-based service Poll Everywhere to replace (or more accurately, extend) multiple-choice clickers as an in-class student response system.  She got students to text or email in their (full sentence!) responses to questions during class and found it to be valuable and very straightforward to use.  It not only relieves the constraint of the dreaded multiple-choice format, but is cheap and requires no investment in new technology (beyond WiFi).  There are several other similar services whose names escape me this late at night.
