CS 115: Introduction to Computer Science 1


Clickers are used in CS 115 to provide instant feedback to students and instructors concerning core concepts, as well as encourage large scale interactive learning. Answering clicker questions will help in monitoring personal progress and is also a very useful study tool.

iClicker Registration

Use this link for iClicker registration. Do not use the link on the box provided with the clicker, as that will not register the clicker for CS 115. Register iClickers as soon as possible, to follow progress online. Clicker grades will be updated regularly to the CS 115 webpage.

Class Participation

Class participation counts for 5% of the final grade in CS 115. This grade is based off the in-class use of iClickers. iClickers can be purchased at the campus bookstore. During weekly lectures, the instructor will ask several multiple-choice questions to be answered using clickers. Each question during lectures is worth 2 marks: one mark for participation (answering the question), and one mark for correctness (getting the right answer). Your final participation grade is taken from the best 75% of your clicker answers over the whole term.

Academic Integrity with iClickers

Students must only answer clicker questions using their own iClicker registered to the course. Using a clicker registered to someone else in the course is an academic offence and will result in disciplinary action. Check it out here in the black additional facts section.


Frequently asked questions about clickers can be found at Clicker FAQ for Students. If a question is not there, please email the CS 115 ISAs at cs115@uwaterloo.ca.
