Clickers



Students


What are "clickers"?

The term "clicker" refers to a handheld device, similar to a remote control. Students use clickers in class to submit responses to an instructor's questions or polls.

How do clickers work?  

Clickers are infrared or radio frequency devices that send signals to receivers mounted in various locations throughout a classroom. The infrared signal sent by a clicker is unique to that clicker and the software interprets the signal (response) as belonging to that clicker, specifically. Thus, the response from a clicker is recorded, stored and used by the instructor in various ways to enhance interactivity in the classroom. 

Where do I get a clicker? 

Clickers are available for purchase from the Campus Store. The cost of a clicker will vary, depending on whether it is used or a new. There are usually a limited number of used clickers available (first-come first-served). Save your receipt as you can return well maintained and functioning clickers to the Campus bookstore and receive approximately half the initial cost. It is also possible to obtain clickers from a previous user (see below).

What is the difference between the two types of clickers available? 

There are two types of clickers in circulation, radio frequency clickers and infrared clickers. Infrared models are a little older than radio frequency clickers and require that you point your clicker more directly at the receivers mounted in the classroom. Radio frequency receivers are not mounted, but rather inside the classroom computer podium, and you do not need to point as directly in order for your response to be received. You will always need to have to locate your number on the projected acquisition grid in order to verify that you response was recorded. If you think your clicker may not be working correctly, let your instructor know in case there's a problem with the receivers in the classroom. Otherwise, see the "Contacts" section of this site for how to seek help.

How do I register my clicker for use in the classroom? 

If required by the instructor, clickers need to be registered each quarter at this site (clickers.ucr.edu) by logging in with your email user name and password. This registration process needs to occur every quarter as the registration database is cleaned at the end of a quarter to allow circulating clickers to be registered to a possible new user. This registration process is required even if you are still the original user. 

What do I do if my clicker does not seem to work? 

Check your clicker by making sure you obtain a red LED light when you click any button. IF you do not get a response, replace the battery or batteries with a fresh battery. See the "Contacts" section of this site for how to seek help If you think your clicker may not be working correctly. If you still have your receipt which indicates that the purchase is within a 90 day period you can return the unit to the Campus Store for a replacement. This replacement policy only applies to new models and is subject to change by the Campus Store. It is always important to save your receipt.

Can a single clicker be shared between two students? 

At the present time this is not possible. The registration process for a particular quarter limits the use of a clicker to a single student. REMEMBER: each clicker is unique and identifies the student owner. 

Tips for Students

Clicker "lockout" feature

UCR Clickers have a feature that prevents students from overloading the receivers with too many responses at once. This feature disables the Clickers for two seconds after each button press. When a button is pressed, and not accepted (for whatever reason), you must wait two seconds before you press any button. If you do not wait for two seconds, all presses are ignored. If your first attempt to respond is not accepted, remember to wait two full seconds before trying to respond again.

Receiving credit

To verify that your clicker response has been received, the clicker should indicate via the red LED turning green, that your response has been received. However, you should not rely on the LED light but rather always locate your number on the projected acquisition grid.
