Classroom polls are a tool that can be integrated into courses of various sizes and structures. Through the use of polls, both instructors and students can gain real-time feedback on student understanding of course material. Below is a non-exhaustive list of polling question types that can be used by instructors across disciplines to achieve their desired learning goals. We have also created a curated list of disciplinary question banks, journal articles, and blog posts about using polls
Recall questions are a straightforward test of student memory of material discussed in the lecture, a reading assignment, or homework problem. These questions are designed to assess if a student remembers the information. They are not structured to assess a student’s ability to apply or understand the concepts. These questions are useful at the beginning of a class when asking students to recall a previous lecture topic. In this way, this kind of question allows students a few minutes to get back into the mindset of your course material and be ready to engage with that day’s material. Retrieval practice also promotes learning, as highlighted in a study conducted by Karpicke 2008.
Example 1: “Thinking back to the lecture, which principle do you need to know to solve the following problem?”
Example 2: “Which theme that we addressed last week does this text engage with as well?”
Conceptual questions can take many forms, but are fundamentally questions that assess a student’s ability to understand the concept presented. These questions move beyond the recall stage and into a higher order of Bloom’s Taxonomy. Furthermore, these questions can lead to productive and effective class discussions (either instructor- or peer-led) because they require a deeper engagement with the material. Three ways to ask conceptual questions (correcting common misconceptions, classification, and student explanation) are described below.
Correcting Common Misconceptions
This style of conceptual questions provides the correct answer as an option as well as multiple incorrect answers that rely on common student misconceptions about a topic. Incorporating such questions is a useful way to highlight and clear up such misconceptions for students. Furthermore, questions written with multiple answers that students may debate can lead to a productive classroom discussion. It is always important to build in time to provide closure for students, but it is especially necessary in this case to ensure students understand why the common misconception is incorrect.
In a classification polling question, the instructor asks students to consider information and determine how to situate it within categories of knowledge. These questions can be a useful way to engage students in a class discussion about a reading or homework assignment and have students draw connections between varied course content. These questions are particularly well designed to foster robust discussion because students often have differing ideas about how to classify information. More specifically, by asking students to classify information and then explain their rationale the instructor is promoting a much deeper engagement with the content. Using classification questions also allows the instructor to gain an understanding of how students are processing the course material and to clarify any confusion.
This style of question asks students to initially respond to the question by writing down their own answers before being shown the instructor generated answer choices. Then, students are tasked with determining which of the options provided by the instructor best matches their written explanation(s). This type of question forces students to consider their or their small group’s, ideas first, and come up with a response rather than relying on the answers provided.
Instructors can also allow students, or groups of students, to volunteer their solutions/answers and ask the class to vote on the accuracy of this proposed solution.
Polls can be a useful tool for identifying in real time if students are struggling with a particular concept or keeping pace with the material presented in a lecture. The muddiest point activity usually involves students writing down the most confusing topic covered in class and turning it in on their way out of class. Obviously, collecting paper from each student is cumbersome for instructors teaching in a large lecture format. Polls allow an instructor to ask muddiest point questions and get feedback from hundreds of students instantly. The results of a muddiest point question can be used to conduct a brief 5-minute review of the most confusing point at the beginning of the next lecture, and may generally inform how instructors present information in the future. Examples of how this polling activity was conducted successfully in a large chemistry class can be found in King (2011).
Example 1: “Of the concepts covered in lecture today, which remains the most confusing?”
Example 2: “What is the topic that we’ve covered during the exam period that you are least comfortable with right now? We will start the review session with the most chosen topic.”
Personal Beliefs or Perspective Questions
In many fields, instructors want to encourage students to provide and defend their beliefs or perspectives on topics in order to engage with the course material and foster discussion. These questions are useful when teaching a sensitive or controversial topic in which commonly students bring their own outside beliefs and perspectives into the conversation. However, providing such personal information or beliefs can prove intimidating for some students who do not feel comfortable speaking in large groups and it can be difficult to ensure that a varied group of students responds to requests for opinions. Polls allow for students to respond in an anonymous format that can be used to engage in a large group discussion. The responses to these questions are also useful to the instructor to ensure that they are being inclusive of students’ personal beliefs when leading a discussion and not making assumptions about the opinions of the students they are teaching. These questions can be used on their own or in combination with another active learning strategy such as Think, Pair, Share.
Example 1: “Which of the following statements most closely matches your beliefs on evolution?”
Experiment or Predictive Questions
In experiment driven pooling questions, the instructor seeks to replicate an experimental result in the classroom or to ask students to predict the result of an experiment or likely outcome of a text. In a social science course, this line of questioning can be used as a way to engage students in conversations about research and illustrate an experimental result. In a physical science class, these questions can test students’ understandings of physical properties or highlight a common misunderstanding that is corrected through the experimental demonstration.
Example 1: The instructor asks “Compared to the average student in this class, my driving skills are . . . 1. Above average, 2. Average, 3. Below average.” Few students will select 3, and this can lead into a discussion and explanation of the better-than-average effect.
Example 2: Before conducting a demonstration, the instructor asks “Of the following outcomes, which is the most likely to occur?”
Example 3: “How will acid effect an intaglio plate in printmaking?”
Example 4: “Based on what we know about these characters so far, what is a likely outcome that we are headed for?”
