what is a clicker?

<p>H was reading rate my professor to see what students have said about several profs our D might have next semester. For one of the profs many students commented that this prof used a clicker or clicker system (something like that). Does anyone know what that is? I never heard of anything like that or what that means. Thank you.</p>

<p>its how they take attendance.</p>

<p>It’s not just for attendance. In big lecture classes they use it. The professor may ask if the class is unclear of something, or they might ask like a multiple choice type question just to see if the class is following him/her, and the clicker is used to electronically enter the student responses. It’s kind of like “ask the audience” on “who wants to be a millionaire” . I have no idea how much it is actually used. They did do a demo in one of the parents sections I had gone to during Delaworld.</p>
