With iClicker and other student response systems, the instructor is able to ask objective and subjective questions of each student. The questions come from a computer, and are displayed for each student to view. Each student can answer their test questions at their own pace and respond with a remote control device ("clicker"). A radio or infrared transmitter picks up the student's response and sends it to the computer, which stores the responses and can provide detailed reports. This system allows instructors to obtain immediate feedback from each student. The system keeps a log of every class session, so student records are always available.
