What is peer instruction?

Peer instruction is when you have students learn by discussing questions in class, generally involving polling and guidance from the instructor.

Scroll down to read about the benefits and range of approaches for peer instruction.

iClicker logoAre you trying to set up iClicker? Here’s some quick info 

Many instructors in the Life and Physical Sciences use iClicker as a polling tool to support student engagement during lecture. Scroll down to learn more about why and how to use a range of polling options for peer instruction.

iClicker Cloud requires instructors to run the iClicker software from their laptops or classroom computer. If you are not using the blue instructor remote and no student is using a physical clicker than the white base is not required. Students can participate using the mobile app on their phones or signing in through the web on their laptops. If you still want to allow a physical clicker then the white base must be plugged in before launching the iClicker Cloud software. iClicker integrates with Bruin Learn to enable grading for participation. For 1:1 support in setting up iClicker instructors can reach out to Melissa O’Brien via her training link or email her directly, melissa.obrien@macmillan.comto meet over Zoom to walk through the setup.

Need an instructor kit? You can pick up an instructor base and remotes from the CEILS office, 222 Hershey Hall during regular business hours. Email to arrange a time for pick-up. 

Student remote registration: Once you have set up your iClicker account you can add iClicker remote registration to your course in Bruin Learn. From your course menu select settings, then navigation. Scroll down to see hidden items and move “iclicker registration” up to be visible in your course menu. 

Note that students pay for iClicker (only one subscription or remote regardless of number of classes requiring it). Additional polling options are provided at the bottom of this page. 

Benefits of Peer Instruction

In this video, Harvard Physics Professor Eric Mazur shares the story of the moment he realized his outstanding teaching reviews were not actually resulting in the student learning outcomes he believed he was achieving – a harsh wake-up call that led him to discover the teaching strategy he named “peer instruction”.

What is peer instruction? Peer instruction refers to the practice of students learning through discussion with peers.

Why use peer instruction? It is one of the most research-validated forms of active learning; the “Research” tab at this AAPT link includes a long list of studies supporting the practice.

Tech-Free Voting Cards for Student Polling


We recommend using iClicker software if possible in order to not only view student responses, but also to be able to analyze the results of your polling by individual student or the class as a whole and award participation points.

However, if you would prefer a non-technology option or want to provide non-technology options to your TAs for their discussion sections, you can use these voting cards. Either print them for students or ask students to print (in color!) and bring one to all classes.

These cards can be folded and held up during class as you ask multiple choice questions.

Advantages and Disadvantages of using Tech vs. Tech-free Polling

This article summarizes the advantages and disadvantages of using a clicker-like polling technology over flashcards or hands. None of these are magically achieved by the clicker itself. They are achieved – or not achieved – entirely by what you do in implementation.

Thought Questions- A New Approach to Using Clickers Teresa Foley & Pei-San Tsai

Niemeyer & Zewail-Foote (2018, Journal of Chemical Education) found that compared to men, women had significantly higher perceptions of the benefits of clickers and their ability to increase student engagement.
