Teaching with “clickers”
What is a “clicker”?
Clickers or Student Response Systems are tools that encourages students to participate in class by allowing them to submit responses to interactive questions. Student can submit answers with a connected device (smartphone, laptop…).
EPFL uses the TurningPoint Student Response System.
An example of use
Student Response Systems can be used in a wide range of contexts and with a lot of different methods.
In the video below (in French), Cécile Hébert, Professor of Physics, explains how she uses this system to maintain the attention and encourage the participation of her students in Materials Science and Engineering and Electrical Engineering.
Teaching with Student Response Systems
Why use Student Response Systems?
Student Response Systems can:
- Increase interactivity and participation in class, and therefore improve students’ attendance;
- Make students more active during lectures;
- Allow students to get feedback on their learning;
- And allow you to get feedback on your teaching.
These benefits are maximised for lectures with a large audience.
Other strategies can also be used as a complement to (or instead of) electronic devices to make students active in the classroom.
How to get started?
This website provides you with both technical information and pedagogical advice to help you prepare yourself to use Student Response Systems in your teaching.
When to get started?
If you are interested in using this system in your lectures, we recommend to start preparing yourself at least one month before the beginning of your course.
What do I need?
EPFL uses the TurningPoint Student Response System.
To create polls and to receive students votes on your computer, you need:
- Access to the EPFL licence to receive votes.
- A TurningPoint account and the TurningPoint software installed on your computer.
What do my students need?
Students will need a connected device to respond to poll questions.
Students will connect to your class on responseware.eu (using a code that you will provide). They can then respond to poll questions as you make them available.
How do I get started?
Turning Technologies has extensive guidance for getting started.
Setting up your account
For data protection reasons, it is important to note that students should not be asked to ‘Sign in’ to the responseware.eu website. Rather they should use the website in ‘guest mode’ without providing identifying information.
You must set your account settings, via TurningPoint account then session settings (see gear icon top right), in order for your students to respond to your polls.
Disable the first 2 options “Enforce Roaster” and “Require Participant Sign In”, select the “Hidden” option for the 4 fields : Last Name, First Name, Email and User ID, and save.
Your sessions will then be configured by default not to request any information from your students. They will then be able to easily connect in Guest mode.
If it is the first time you are using a Student Response System, we suggest you to ask for personalized support or to register for our “hands on” workshop on “clickers”. More information here.
Student Response Systems are not particularly useful or revolutionnary in themselves. They are just a tool, and what really matters is how you use it.
Below are some key factors of success when designing a Student Response System based course.
1. Prepare your questions
- Focus your questions on concepts that are important and challenging for students to learn (you will spend lecture time on those questions, time that you will not be able to spend on something else)
- Use simple question types like MCQ so that students focus on understanding the content of your question, not its form
- Choose carefully the formulation of questions and of the response options
For each question, we suggest checking the following points:
|Why ask this question?||
|What do you ask?||
|How do you ask?||
|When do you ask?||
2. Re-think the structure of your course
- More interactivity = less lecturing! A typical one-hour lecture can include 3 to 4 questions. But you can also structure an entire lecture around clicker questions…
- Choose the key moments at which you will ask a question depending on your goal
(e.g. assess prior knowledge, assess understanding, detect misconception, apply knowledge, relate to other concepts…)
3. Prepare to interact with students around questions
- Prepare yourself to react to students’ responses – first because you can get unexpected results, but even when all students have the right answer, it is important to debrief it with them (even very shortly) because they may have chosen the right answer for the wrong reasons…
- Use the results of the vote in your lecture, e.g. to introduce your next lecture part, to start a debate, to adapt the plan of your lesson, etc.
- Use an interaction strategy to maximise students’ participation (see “Teach effectively with Student Response Systems – interaction strategies” below).
For data protection reasons, you need to provide students with information about how responses are processed. You can find the legal information required here [legal information]. A slide you can use in class is provided [slide]. (VPN connection is required if you are not on the campus !)
Students will access your poling questions on responseware.eu. You will need to provide them with the ‘session ID’.
In particular it is important to note that students should not be asked to ‘Sign in’ to the responseware.eu website. Rather they should use the website in ‘guest mode’ without providing identifying information.
A typical lecture with Student Response System follows this general pattern:
- First present a short part of the content of your lecture (10-15 min.).
- Then ask a question.
There is more information below on how to ask a question effectively.
- Make students vote.
- Use the results of the vote : debrief with students, start a whole-group discussion around the “why” and the “why not”, adapt the plan of your lesson…
You can then ask another question, or start to present the next part of your lecture.
A one-hour lecture can typically include 3 to 4 questions.
How to ask a question effectively?
Asking a question is at the same time simple and delicate.
Be sure to follow these 5 steps:
- Display the question. You can read it out loud for students and give explanations if necessary but keep it short.
- Start the polling and give short voting instructions, including an indicative timing information e.g. “I give you 2 minutes to think about your answer and to vote”.
Step back, don’t say anything. Just monitor the evolution of the number of votes or the level of noise in the room. When noise decreases or when you have a sufficient number of votes, jump to next step (but note that there no point in waiting for a 100% response rate…).
- Announce the imminent closing of the poll and wait 30 seconds for last minutes votes.
Count down, then close the poll.
- Display the results and debrief with the students.
How to encourage participation?
Student Response Systems are not magical, the participation rate is never guaranteed. That is why we suggest you to:
- Explain to your students why you are using Student Response Systems and how it can help them learn.
- Start smoothly e.g. with a simple question (like a demographic), an ice breaker or a “testing the system” question. Help them feel safe interacting with you – it may take time to install a participative climate in a student group.
- Use clear and short instructions.
- Give students time to think.
Use silence and wait for votes without doing anything – silence is tough, but if you keep talking they will listen to you instead of thinking and answering your question.
- Ask the students to discuss their answer with their peers before voting.
Verbalizing and sharing their reasoning with others will reassure them and they will be more willing to participate. During discussion phases, walk around in the classroom to get feedback on what is happening.
- Adapt to what is happening in the classroom.
Be flexible on the participation rate and on the timing – give more time if students discuss a lot the question, stop the polling if students are starting to talk about last night’s party.
- Always encourage students to share their reasoning and explain their answer.
When a student gives a wrong answer in front of the others, don’t express any judgement on it. Instead, ask students who have voted differently to share their answer. Only after that, confirm which is the correct answer and why, and ensure that it is clear for everyone in the classroom.
Below are examples of strategies that you can use to generate interaction in your class using Student Response Systems. These strategies build upon two key principles:
- Give students time to think about their answer to the question in order to generate their own opinion.
- Allow students to discuss their answer with others, having a chance to explain the reasoning behind their answer and confronting it to the reasoning of others.
This strategy is the Student Response System-based version of the Think-Pair-Share activity (Lyman, 1981). The peer discussion part of this strategy gives students the opportunity to check their answer before sharing with the whole class, therefore decreasing barriers to participation. This strategy is therefore very useful for difficult questions where several answers are possible, or when your participation rate drops.
How to proceed?
You may also include a voting step between phases Think and Pair so that students commit to their individual answer before discussing with others. In that case, we suggest you not to show the resulting graph to students so that it doesn’t influence too much their opinion. With this additional step, this strategy is then very similar to the Peer Instruction strategy described below.
Developed by Harvard physicist Eric Mazur, Peer Instruction (Mazur, 1997) is a research-based, interactive teaching method which uses peer discussion as a way for students to deepen their understanding of a concept by learning from each other.
The figure below illustrate the principles of this method. In class, you start by giving a short lecture on a core idea or concept (you may also have asked to students to study more detailed material at home). Then you ask a “clicker” question designed to expose common difficulties in understanding the material. If the results of the poll show that students are divided on the choice of the correct answer, you ask students to discuss the question by pairs or in groups. During this process, students verbalize their reasoning, debate and assess their understanding of the concepts, which is the goal of the method.
How to proceed?
After the peer discussion phase, the results of the second poll should show an increase in the proportion of correct answers.
However, it may happen sometimes that answers stay spread or even that the proportion of wrong answers increases. This is usually the symptom of a misunderstanding – either the concept has not been understood or the question or its distractors are not clear enough.
In such a case, it is recommended to start a whole group discussion to identify the reasons of the misunderstanding. You can ask students to advocate for the choices they made, e.g. “Can someone who answered B tell us why they made that choice?” or “Would someone like to explain why they picked the answer they did?”. It is very important to welcome their answer without commenting on it right away until several opinions have been heard. At that point, you can moderate a debate among students or clarify as needed so that the correct answer is clearly identified.
