This looks interesting Students who use ‘clickers’ score better on physics tests. I’d like to do some in-class polling of students (probably for the large General Education paper I’m teaching next year) – to be able to elicit a poll on a subject in order to spark discussion or emphasise a point, and also to check whether key concepts have been picked up in a lecture.
Now one way to do it would be with ‘clicker’ technology, though that isn’t very widespread at all in NZ (but I stand to be corrected). The other way would be to take an ‘Idol’ approach – TXT/SMS messaging that’s collated automatically and the results put up on an internal web page or such. Different costs, I guess. The one-off cost of the clicker against the ‘micro’ costs of txt-ing. Given the ubiquitous nature of mobile phones in the NZ context, perhaps working towards the TXT approach would work.
In a class of 300-odd doing the non-anonymous survey of hands doesn’t really cut it.
