Classroom Polling

allows instructors to quickly ask a question and instantly receive responses from each student during class.  Polling is used in class while presenting course material. Power Point or KeyNote are popular choices, but any method of presenting course content can be used – MS Word documents, PDF documents, web pages, etc.

Polling may be either:

  • conventional with student using purchased clickers remotes and the instructor using software to collect and display the responses
  • mobile/web, which uses online software or mobile app with your students’ web-enabled device (e.g. a cell phone, smart phone, iPad, tablet or laptop).

Want to get started using i>clicker for your classroom polling?

Sign up before the spring 2017 term for a session to see how it works and to get your own instructor kit and the software.  Sessions are hands-on for you to set up the i>clicker program for your course and connect your Blackboard class roster (if applicable).  For details, go to the Registration Page and look for i>clicker: Classroom Polling to sign up for one of 4 sessions.

Learn more about this service and listen to instructors share their experiences with using classroom polling.   A Classroom Polling Webinar Event was held on February 24, 2016.  The 41-minute recording of this session is below:

Conventional polling at Cornell is provided using the i>clicker brand of in-class polling software.  A receiver base is connected to the instructor computer during lecture and the i>clicker software runs on the instructor’s computer.  As each student chooses their answer to the question presented in class, a wireless signal (radio frequency) is sent immediately from each responding clicker to the receiver base.   The receiver base collects votes sent by the students’ clickers.  Light and portable, the receiver base is powered through the computer’s USB port.  The receiver base, through i>clicker’s easy-to-use software, stores the data of each individual student. The instructor can then display voting results in a graph to the class, including the correct answer, if desired. The results are also available for later analysis, grading, and exporting to any grade book software or course management system, such as Blackboard.

Mobile and web polling: Students may also use their smart phones/laptop computers/iPads/tablet computers in class instead of an i>clicker remote using the REEF Polling subscription app.  This is only allowed if the instructor chooses to allow it in class.  The student responses are displayed just like clicker responses, with the same results and analysis capabilities as with clicker responses.  The instructor’s i>clicker program collects and records both methods of students responses at the same time.

There is no fee for Cornell instructors and staff to use i>clicker for their instruction. Each student is required to purchase an i>clicker remote or a subscription to REEF Polling. The Cornell Book Store sells used or new i>clicker remotes for between $30.00 – $43.00, just like a text book for a course. But unlike a text book, one student remote can be used by that student in multiple courses in a given semester and the same remote can be used in multiple semesters throughout a student’s time at Cornell. For details on how to use i>clicker, see the i>clicker Basics page.  Full details about mobile/web polling can be found at the Mobile/Web Polling page.

Other mobile and web polling options are also available that are different from i>clicker/REEF Polling.  These other products use a web site to present questions and collect student responses.  Students use their smart phones/laptop computers/iPads/tablet computers in class using apps and web pages to respond to the questions through either  a subscription to a specific product or the instructor’s department pays for the student use of the product.  Products that are being used at Cornell are Poll Everywhere and Learning Catalytics.  These products are also supported by the Academic Technologies support staff.  For more information about these options, please contact us at
