A free way to use a "student response system"

Teachers,

There are many types of "student response systems" available for use. Most of them are "clickers" that allow the software to show responses on a screen from a projection device. There is a simple and free way to take these types of "polls" with your students. Using the website http://pollanywhere.com you can create a poll with real time results for free with up to 30 responses. Responses can come from the Internet from a website or can be answered by cell phone. This might be a way you can get feedback on a homework assignment if the students are using their home computers or in a computer lab. Try it, take my poll:
