I am old enough to remember the large suitcases full of little devices that were handed out to students who could then use them to vote in class in response to questions posed by the lecturer taking the class. The cumulative class responses could be magically displayed at the front on the big screen.
These days there are handy web based systems like Polleverywhere that can be used in place of the clickers. relying on the student’s own smart devices, polls authored in polleverywhere can be downloaded as aPowerpoint slide for use in class. Alternatively the poll can be delivered fully online hosted by Polleverywhere. A third more recently developed way to use Polleverywhere is to wrap it up with the use of Twitter. The poll can be tweeted to a twitter stream and respondents can answer by tweeting.
And, to top it all, Polleverywhere is free to use for class sizes up to 30.
In class voting can be an integral component of a SMART teaching strategy. Find out more at polleverywhere.com
