iClicker - Audience Response System

The iClicker audience response system is a polling system that uses a handheld remote (clicker) to collect student responses to questions posed by the instructor. Student data is recorded and then displayed on a results graph via software on the instructor’s computer.

 iClicker is the centrally supported audience response system on the UMass Amherst campus. 

Mobile Audience Response at UMass Amherst

At this time, the best solution for classroom audience response is the iClicker Classic software, the iClicker base station, and the iClicker 2 handheld student remote

Starting in Fall 2017, students who purchase an iClicker model 2 will receive a 5-year subscription to the REEF polling app. Going forward, this should position us to have a tested, reliable mobile polling option in place for students and instructors after we complete our pilot of iClicker Cloud/REEF, and we continue to make improvements to our classroom WiFi infrastructure. (Note: students who purchase an iClicker 2 with 5-year REEF access starting Fall 2017 should create and register their REEF accounts right away.)

We are asking instructors not to use REEF and other mobile polling apps (e.g.,TopHat) for most on-campus courses. Currently, there are only a few buildings and classrooms that have the wireless network capacity to support the performance that instructors and students need for high-stakes mobile polling.

If you are a student, your instructor will let you know if your classroom can support mobile polling, and your course is using REEF. For instructions on how to create a REEF account and how to redeem the subscription access code bundled with your iClicker 2 remote, go to Create Your iClicker REEF Account and Redeem Your Access Code.

iClicker for Instructors

IT will also be installing receivers in the classrooms where clickers are often used. Please let us know what classroom you will be teaching in each semester.

If you want to use iClicker in your course, please follow these steps: Before You Begin Using iClicker.

For steps to take prior to using iClicker in your classroom (even if you have used iClicker previously), please see Prepare to Use iClicker.

Students will register their clickers in a dedicated iClicker block that you will need to add to your Moodle course. For instructions on how to add the iClicker block to a Moodle course, please see Add an iClicker Block in Moodle.

Be sure to purchase the correct clicker. The UMass Amherst campus is only supporting the iClicker model 2, which has an LCD panel (see image on the right), and is available through the eCampus online store (instructors will provide the link to the store in SPIRE).
