How to Access iClicker/Reef


Instructor Kit

Faculty interested in using iClicker can order an instructor kit by submitting the "request an instructor kit" form. The kit includes a base receiver, USB cable, student remote, and an instructor remote.

Note: Some UAB classrooms have iClicker receivers (base unit) already installed. View the Classroom Technology page on the UAB Information Technology website and choose desired classroom. The room will say “Clicker Ready = Yes” if the base is already installed.

For all other classrooms, you will need to use the individual receiver that is included in the instructor kit.

Download Software

Once you have your instructor Kit, download the iClicker software that is required to run the polls.

Provide Canvas Link to Students

The iClicker Registration link can be enabled in desired Canvas courses so that students can register their remotes to their UAB email address.


Purchase iClicker Remote

Students can purchase iClicker remotes or Reef access via the UAB Bookstore.

Register Remote/App

Students can register their iClicker remotes via the iClicker link in their Canvas course left navigation. You can also use the Reef Mobile app if allowed by your instructor.

iClicker/Reef FAQ

Do my students need to register with iClicker before I start running polling sessions?

No, students do not need to register their iClicker remotes before iClicker Classic can collect and record votes. Student registration must occur at some point in the term, and the steps for doing so vary depending on how you will be adding grades from iClicker cloud to your LMS.

When students participate in polls before registering their device, responses will be associated with their respective remote IDs. Therefore, you can use iClicker to run polling sessions starting on the first day of class, eventually connecting all students to their remote IDs through either roll call registration or registration at the iClicker website.

To participate using the iClicker Reef mobile app, you need to enable Reef in your course settings. Then, students need to create an iClicker Reef account or log into their existing account, add your course, and click "Join" when you start a session.

What presentation softwares does iClicker Classic work with?

iClicker works with any presentation software, including PowerPoint, Prezi, Google Slides, Keynote, and more. Simply incorporate your questions into your presentation; preloading questions or answers into the iClicker system is not required.

The iClicker toolbar floats in front of whatever material is on your screen, enabling you to ask polling questions at any point during your class. You can also jump out of your presentation and ask questions spontaneously. Each time you start a polling question by clicking the play button, iClicker takes a screen shot for you to review later, so you always have a record of the questions you asked in class. No additional work on the instructor’s part is required.

If I have enabled iClicker Reef in my iClicker Classic course, how will remote or distance learning students participating with iClicker Reef know the questions I am asking?

iClicker Reef can display screenshots of your questions to students in real time. You can manage this setting at any time in the Mobile tab of your Course Settings.

Can the iClicker instructor software receive votes from iClicker remotes and Reef at the same time?

Yes. As long as a base is plugged in, Reef is enabled, and Reef students have access to WiFi, the iClicker software will receive votes from iClicker, iClicker+, iClicker 2 remotes, and iClicker Reef.
