CS 136: Elementary Algorithm Design and Data Abstraction, Winter 2019


We will be making use of iClickers in lectures and tutorials to engage students and provide instant feedback. New iClickers can be purchased at the UW bookstore in South Campus Hall for around $50. You can also buy a used iClicker which is cheaper. CS 136 does not support iClicker Go or clickers for mobile devices. When using your iClicker in the classroom, make sure you've set the frequency correctly. The frequency must be set at the beginning of every class. The frequency code for the classroom is a two letter combination that is usually posted on the wall near the front of the room. After you cast your vote, the Vote Status light on the clicker should flash green.

You must attend the lecture section you are registered in to receive participation marks. If you do not attend your registered lecture section, you will not get any participation marks.
Clicker marks are posted on the View Marks page about one week after the lecture. If you have problems with your clicker marks, refer to the Common Clicker Questions and Issues section below. If you are still having any issues, please submit a request tagged "iClicker" to the CS 136 Course Staff.

Due to university policies on academic integrity, you may not bring a friend's clicker to class and enter answers for him or her. You may not share clickers with other students.

iClicker Registration

Click here to register your iClicker.

You must register your iClicker using the link above so that we can assign marks appropriately. If you want, you can register your iClicker on other websites but you must register your iClicker using the above link to earn any marks for CS 136.

If you decide that the 5% participation mark is not worth buying an iClicker, you can forfeit the 5% participation mark. However, you still have to register here to complete Assignment 0. In this case, use your eight digit student ID number as the iClicker ID.

Common Clicker Questions and Issues

  • How do I check my clicker participation marks so far?
    See "Why aren't my clicker marks up-to-date on the course website?" before using the View Marks link (in the table of contents on the left).
  • Do I have to bring my clicker to lectures/tutorials?
    Clicker responses in lectures count toward your 5% participation mark in the course. For each tutorial you attend, we’ll increase your 5% participation grade 0.1% (up to 1.2% overall, you cannot exceed 5%). Refer to the course notes Introduction module for more details on grading.
  • What if I have to miss lecture because I am ill/have Co-op interviews/slept in, etc.?
    If you can't attend your lecture, you are welcome to attend another, if there are enough seats after those who are registered in that section, but clicker marks won't be counted (though the learning and understanding will help on assignments and exams). Please note that giving your clicker to a friend to use in your absence is an Academic Violation for you and your friend; the same penalties as cheating apply.
  • What happens to my participation mark if I forget to bring my clicker to class or it isn't working?
    If it isn't working, try to figure out the problem as soon as possible (see other questions and answers). Information about your participation mark can be found in the course notes in the Introduction module.
  • What do I do if I switch lecture sections or get a new clicker?
    If you switched lecture sections, this change will be reflected on our system one business day from when the change was made official on Quest. All your clicker responses from the old section will still be recorded from when before the change was made. Your clicker reponses from the new section will start being recorded after the change is made on our system. If you get a new clicker, you have to re register with the new Clicker ID number here. Your responses from your old clicker which were made before registering the new clicker will still be recorded. Once the new clicker is registered, any new responses from the old clicker will stop being recorded.
  • What do I do if I have been using an unregistered iClicker?
    Register it here. You will still be given credit for any responses you made before you registered the clicker.
  • How do I know if my clicker is working?
    After answering an active question, a light on your clicker will blink green to indicate the answer was properly received. If you are using an iClicker2 refer to the feedback on the built-in screen.
  • Why aren't my clicker marks up-to-date on the course website?
    Clicker marks are not always immediately updated after lectures (but they should usually be updated by the end of Friday). If it has been more than a week since your marks have been updated, check if your clicker is registered and working.
  • I accidentally pressed the wrong answer button
    We only record the last answer that you submit. If you resubmit the correct answer before the question ends, you will still receive full marks.
  • The light is turning red whenever I submit an answer
    A red light means your answer is not recorded/recognized. Make sure your clicker is set to the correct frequency for your current room. You can do this by holding the power button for a few seconds (until the power button starts flashing), and then enter the two letter frequency code for your lecture room, posted at the front of the room.
  • My participation marks say I did not answer x out of y questions but I know I did
    See "How do I know if my clicker is working?" and "The light is turning red whenever I submit an answer" above. Are you attending your registered LEC section? Did you register your clicker ID with us (see "What do I do if I have been using an unregistered iClicker?" above) or possibly register with the wrong clicker ID (contact course staff to check)? If none of these problems apply to you, please submit a request tagged "iClicker" to the course staff.
  • What versions of the iClicker work?
    The original iClicker, iClicker+, and iClicker2 will all work. We do not support the iClicker app and other web-based clickers (e.g. iClicker Go).
  • How do I turn it on/off?
    Briefly press the power button. Holding the power button will instead change the clicker frequency.
  • My clicker keeps turning off
    Your iClicker will automatically turn off after a few minutes to conserve the battery. You may also want to ensure that your batteries aren't very weak or have died.
