iClicker Information


Participation in the PHYS 101 Lectures requires the use of iClickers or the iClicker cloud app.

Using an audience response system, such as iClickers, improves lecturer-student interactions.

The more you interact with your lecturer the better you will learn the material.

You may choose whether you will use a physical iClicker or the iClicker Cloud app

To use the physical iClicker you must:

To use the iClicker Cloud Student app you must:

Registering and Adding yourself to the Physics 101 course

  1. Create an iclicker Student account at or in the mobile student app using your email address, or log in if you already have an account. If you use a different email address your grades will not import correctly.
  2. If you will be using a physical remote, register your Remote ID when prompted. If you will be using the app to answer poll questions skip this step.
  3. Add yourself to the Physics 101 course using this join link or by searching:
    • Institution: University of Illinois at Urbana Champaign
    • Course: Physics 101 (Both lectures)
  4. If you will be using the app to answer poll questions, you will need to pay for a subscription after the trial period expires. These subscriptions work for multiple courses, so if your other classes use iclicker cloud you only need one subscription.

For additional help with registration, try this illinois answers page on registering with iClicker Cloud.


You will receive one point of credit (out of 1000 total for the course) for every lecture in which you participate using the iClicker. Participate means answering at least 50% of the questions (not necessarily correctly) asked in that lecture.

You will receive one bonus point of credit when you answer at least 50% of the iclicker questions correctly during at least one of the lectures in a week. You can only earn one lecture bonus point each week.

NOTE: Although we encourage you to attend the lecture to which you are assigned (to keep the sizes balanced), you can get clicker credit at any of the lectures on a given day. However, each student can get credit for only one lecture per day. (This means that you should NOT share your clicker with another student registered for the same course -- only ONE student will get the credit.)

The awarded points will show up in the gradebook approximately at the end of each week.

How do I know if the system registered my answer?

There are two different versions of the iClicker:


The batteries should easily last the entire semester. In any event, if they are starting to go, the clicker will flash, letting you know; you should still have enough power for another few lectures after that, i.e., there's no good excuse for not getting new batteries.


Q: I have purchased a subscription for iClicker Cloud for another class. Can I use it in this class also?
A: Yes. We are set up to use physical iClickers and iClicker Cloud this semester.

Q: I have purchased and registered an iClicker for Psych 100. Can I use it in this class also?
A: You can use any kind of i>clicker in this class, old or new.

Q: How can I register my iClicker for this class?
A: You can register it at iclicker cloud by following these remote registration instructions.

Find your iClicker registration number

Q: My clicker always says "NO BASE" when I try to send a vote. What can I do?
A: Make sure your frequency is set to the frequency announced by your lecturer at the beginning of class.

Q: Do I have to change the frequency of the iClicker?
A: Your lecturer will announce the frequency used in the lecture hall.  Make sure your iClicker is set to the frequency announced by your lecturer.

Q: How can I tell if my iClicker is working?
A: If a green light flashes on the models without the LCD screen, or if you see a check-mark on the LCD screen, then you can be sure that your vote was counted. If you don't see this you may be on the wrong frequency, or you may just need to vote again.
