Southwestern Should Use The Tuition Increase On These

From NY Times:

For these and other professors across the nation, the newest aid in the classroom is a small wireless keypad, linked to a computer. Students answer questions not by raising their hands but by punching buttons, with the results appearing on a screen in the front of the room.

Although some skeptics dismiss the devices as novelties more suited to a TV game show than a lecture hall, educators who use them say their classrooms come alive as never before. Shy students have no choice but to participate, the instructors say, and the know-it-alls lose their monopoly on the classroom dialogue.
