'Clickers' let professors quiz big classes instantly

Handheld devices that resemble TV remotes are catching on in large University of Wisconsin-Madison lecture halls, a professor says.

But that doesn't mean students are kicking back and watching Comedy Central – the 'clickers,' which usually have about a dozen buttons, let them respond instantly to multiple-choice questions posed by their professor. The anonymity is an encouragement to some students who might feel embarrassed to raise their hands and be caught in a wrong answer.

The university also uses software that makes up charts of their responses automatically and inserts them into class presentations.

Clickers cost students about $25.
