Response Card Clicker?

[alexthelion]

Hi, I am taking my first college physics class, and it says I need a response card clicker. Does somebody know what this is? What's its purpose? What does it do? How does it help me learn?

Just wondering, any answers would be appreciated.

It really serves no purpose for you. It's just a tool that lets teachers essentially take attendance by giving you little mini quizzes. Aside from that, another way for the university to get more of your money.
