The students in Michael Dubson`s physics class at the University of Colorado fell silent as a multiple choice question flashed on a screen, sending them scrambling for small white devices on their desks.
Within seconds, a monitor on Dubson`s desk told him that 92 percent of the class had correctly answered the question on kinetic energy, a sign that they grasped the concept.
Clickers -- not unlike gadgets used on television game shows -- first appeared in college classrooms over a decade ago and have since spread to just about every college and university in the country thanks to cheaper and better technology.
But as clickers have become commonplace, a divide has emerged over just how sophisticated they should be.
Some professors like Dubson endorse simple, straightforward devices that stick to multiple choice questions. Others embrace fancier models or newer applications for smart phones and laptops that allow students to query the professor by text or e-mail during the lecture or conduct discussion with classmates -- without the cost of purchasing a clicker.
Those preferring simplicity say pared-down remotes reduce distractions in a multitasking world, while others say fighting the march to smart phones and digital tablets is a losing battle.
Clickers first gained popularity in large science lecture halls as a way of gauging whether students understood the material. They have since migrated into smaller classrooms and can be found in nursing and other professional schools. Even middle schools and high schools are using them.
Research at the college level has found that students like using the devices and attendance often goes up. But results are mixed when it comes to learning. Some evidence suggests clicker use has led to only modest gains in retention and test scores, while other studies have detected little or no improvement, according to a November article in the North American...
