5. What is your experience with clickers? What is a clicker? I’ve heard about clickers but haven’t seen them used. I’ve seen a demo, but not used them. I’ve been a student in a class that used clickers. I’ve used clickers a small amount in my teaching. I’ve used clickers extensively in my teaching.
6. Which best describes your attitude towards teaching with clickers? I’m interested in using them regularly. I’m interested in experimenting with them a little. I’ll need to hear more about them before deciding to try them. I don’t think I’ll be using clickers anytime soon.

29. Creating “Times for Telling” Through accounting procedures, it is known that about 10% of the employees in a store are stealing. The managers would like to fire the thieves, but their only tool in distinguishing them from the honest employees is a lie detector test that is only 90% accurate. That is, if an employee is a thief, he or she will fail the test with probability 0.9, and if an employee is not a thief, he or she will pass the test with probability 0.9. If an employee fails the test, what is the probability that he or she is a thief? 90% 75% 66 2/3% 50%

40. Responding to Results? Consider whether or not to display initial voting results to students. If students are mostly correct, hear from a couple of students to confirm. If students are split, have them reengage with the question and then revote. If students are mostly wrong, they will likely need some assistance before they can reengage with the question.

Now’s a good time to talk about distribution options. At some schools, students purchase clickers at the bookstore like textbooks and use them for multiple courses. In these cases, students typically register their clicker through a course management system like Blackboard or WebCT. Instructors can then download that registration info so they can link clicker responses with students for grading purposes.At other schools, departments or schools purchase sets of clickers that instructors borrow on a per-class or per-semester basis. Students pick up clickers on the way into class and return them at the end of class. In these cases, students can be instructed to pick up the same clicker each time, allowing instructors to link clicker responses with students for grading purposes.
