A new device, The Clicker, is being implemented throughout colleges nationwide so that professors can instantly see if students understand lecture material. The Clicker is meant for college professors who teach in giant lecture halls or auditoriums. At any point during the lecture, the professor can send a digital, multiple-choice question through The Clicker and ask if students understand the lecture material. Students are not thrilled about The Clicker because they have to pay $25 for the device. Clark thinks The Clicker is addressing the wrong problems in colleges. He can’t get over the massive class sizes, and he believes the large auditoriums are the real issue
