Two years ago when the TLtC first wrote about audience response
systems (also known as clickers or student response systems), only the most
technologically adventurous of instructors were using them. Since then the use
of these devices has blossomed, especially in large-enrollment science courses
in which engaging students can be a challenge. Most instructors use the systems
to survey students about their knowledge of concepts and to increase classroom
participation, although some faculty in the political science and psychology
fields are using the technology to demonstrate polling techniques and to provide
insight into human behavior (see a UC Davis paper about real-time
polling ).
Today, the Davis and Los Angeles campuses are piloting audience
response systems campuswide and instructors throughout the system continue to
experiment with them on their own (publishers often give them away to encourage
purchase of their textbooks). Riverside has taken the biggest plunge by
installing audience response systems in all of its 66 general assignment
classrooms. According to Leo Schouest, Manager of Faculty & Student Technical
Support at UCR, 19 faculty are using the systems this quarter in psychology,
chemistry, physics, and other disciplines. Schouest says the use of these
systems is leading to dramatically increased attendance, more engaging lecture
sessions, and greater class participation among all students (even the "shy"
ones).
Schouest and his colleagues in the Computing and Communications
department have tried to simplify the use of these systems in multiple ways so
that faculty can focus on their teaching -- not on the technology. The campus
has standardized on one system, the infrared H-ITT system (radio frequency is
the other type of system; see a comparison ).
Standardizing also saves the students money because they only have to purchase
one clicker for their entire academic career. The computing department has
created a companion web site
to teach faculty how to use the system and to share best practices as well as to
enable students to register their clickers (so that their responses during class
are attributed to them).

Systems

Columbia Center for Education Research and Evaluation, which provides an overview
of "clicker" technology . The Center also offers specific
tips on effective educational uses of these systems. Also, the EDUCAUSE
Learning Initiative's " 7 Things You Should
Know About Clickers " offers pros, cons, and general information, all in a
concise format. Finally, the University of Victoria is planning a study on the academic
benefits of clickers.
