Interesting interview in today's issue of Inside Higher Education about clickers in the classroom. It announces that there is a new book out called Teaching with Classroom Response Systems: Creating Active Learning Environments by Derek Bruff at Vanderbilt, and contains a short interview with Mr. Bruff. He describes some of the benefits of using clickers, such as working with a large class. He notes that students don't really appreciate the use of clickers just to administer a quiz, but notes that there are many other, more substantive uses of clickers in the classroom. I have found this to be true as well, and describe my own experience using clickers when teaching administrative law in the LS2 book (on pp. 94-97).
After the article, scroll down for a comment posted by Bill Goffe, a Professor at SUNY who has some experience with clickers. He has some good links to additional resources about clickers in the classroom.
