iClicker Information


Participation in the PHYS 211 lectures requires the use of iClickers.

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 must:


Please register your iClicker in the student gradebook.


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 75% of the questions (not necessarily correctly, though) asked in that lecture.

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

Q: How can I register my iClicker for this class?
A: You can register it in your course gradebook.

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.
