17 Types of Questions for Teachers in the Classroom

Questions are the foundation of almost any class, but knowing when to ask the right ones may require some pre-planning. Educators can use different types of questions in teaching to check on a student’s understanding, spark discussion, or help others learn from their peers.

Of course, you may have the perfect list of questions to ask, but keeping students engaged and talking can become another hurdle. We’ll go over different strategies for designing effective questions and how to handle various situations, such as incorrect answers or silence. Plus, we’ll show you how tech like Poll Everywhere can help you engage your students with interactive presentations and questions .

How to design effective and engaging questions (and get students to respond)

Keeping students engaged while you ask questions designed to measure their level of understanding is an art. Here are some steps you can take to thoughtfully craft different types of questions for your classroom:

Planning what types of questions to ask

• Choose a goal for asking questions: This helps you decide which types of questions used in teaching are best for your needs.
• Decide what course material to base questions on: It’s better to choose content you feel is important to the overall learning objectives noted in your lesson plan.
• Plan critical questions ahead of time: While it’s okay to formulate questions as the class progresses, it’s important to plan questions you deem essential to gauging students’ learning or prompting critical thinking ahead of time.
• Adapt questions to students’ knowledge levels: Make sure your questions challenge your students' understanding of newly presented topics or assess their foundational knowledge—using a diagnostic assessment before and after the semester can help gauge current knowledge.
• Use a variety of question types: Using a variety of question types—even for the same concept—can help students better grasp the course material by prompting them to think about their answers in different ways. Using Bloom’s Taxonomy to develop multiple levels of questions for the same topic is helpful.
• Anticipate possible answers: This helps you ensure the phrasing of your question isn’t too vague or misleading, as well as whether the questions match your learning objectives.

Asking questions

• Phrase questions clearly: Ensure your questions are unambiguous and are phrased logically so students don’t misunderstand or end up more confused.
• Allow time to process the question: Don’t be afraid of silence—it likely means your students are contemplating the question and thinking through their responses. You should always wait a moment for students to process the question before rephrasing or assuming they don’t understand.
• Avoid including the answer in your questions: If you’re assessing students’ comprehension, including the answer in your question defeats the purpose and likely won’t encourage engagement.
• Vary the types of questions you ask: By varying the questions you use in your teaching, you can prompt students to think about the material in different ways.

Assessing student responses

• Follow student responses with reflection: A reflective statement (e.g., “It sounds like…” or “What did you mean when you said…?”) helps you show you’re listening and double-check your understanding of the response.
• Ask students to elaborate: Similar to making a reflective statement, you can outright request that a student elaborate on their response. This can help you really dig into their level of comprehension and may also help other students who are listening in by giving them insight into their peers’ thinking processes.
• Know how you’ll handle incorrect answers: Have a game plan in place in case students answer incorrectly. This not only reduces the chance of confusion but also helps you confidently guide the discussion so students can come to the correct answer and understand why their original answer was incorrect.
• Encourage other students to chime in: Turn a one-way conversation into a discussion by inviting others to offer their opinions or state if they agree or disagree (and why).
• Use positive reinforcement: Make students feel confident and glad they responded by smiling, using positive statements, nodding, and making eye contact. This positive reinforcement can help students feel safe when responding—or when asking questions.
• Keep track of who’s responded: While some students are eager to offer their two cents, others may be more reluctant. You can create a more inclusive and inviting discussion by allowing a variety of students to share. If you teach a hybrid class, be sure to include both in-person and remote students as well.

3 strategies for addressing incorrect answers or surface-level understanding

If your students don’t respond with a satisfactory answer, you can take advantage of that time to help students understand what they got wrong and what the correct answer is. Three different strategies for guiding students to a better understanding of the topic include probing, redirecting, and refocusing.

• Probing: The probing strategy encourages students to use critical thinking to analyze their answers. This may involve uncovering relationships by comparing and contrasting different concepts, or instructors can ask students to clarify their ideas by providing examples. Additionally, educators can help students pinpoint assumptions used to justify their answers.
• Redirecting: By using redirection carefully, you can invite other students to correct a peer’s incorrect answers. This strategy also encourages more students to participate in the discussion by asking if they agree with the answer or if they can provide an example to support the answer. Just be sure to lay out ground rules before opening up a discussion based on one student’s thoughts to avoid unnecessary conflict.
• Refocusing: Instructors can refocus students if their answer doesn’t quite fit with the content being discussed. For example, let’s say you ask, “What’s one way our modern food system is making people sick?” and a student responds with, “Doesn’t it encourage us to overeat?”—you might refocus the discussion to discuss how not all calories are nutritionally equal by asking, “Yes, but what if we’re talking about not just caloric intake but nutritional intake as well?”

How to use Bloom’s Taxonomy to craft engaging questions

Bloom’s Taxonomy is a framework intended to define different levels of learning and help teachers assess student progress. You can use this concept to develop questions that assess students’ levels of understanding. According to Bloom’s Taxonomy, there are six different levels of understanding: remember, understand, apply, analyze, evaluate, and create.

Remember, understand, and apply questions are typically used to assess learners’ comprehension to see whether anyone needs additional assistance grasping the course content. Analyze, evaluate, and create questions are more often used to encourage deeper critical thinking and problem-solving, or to spark discussions.

If you start with higher-level questions associated with the analyze, evaluate, and create levels and students aren’t sure of the answer, asking a follow-up question related to the lower levels of remember, understand, and apply can help you judge whether your learners understand the course material or not.

Here are some examples to help you craft your own questions based on Bloom’s Taxonomy:

• Can you describe ____?
• When did ____ happen?
• Which is true/false, ____ or ____?
• What does ____ mean?
• How would you show ____?
• How would you compare/contrast ____?
• What’s the main idea of ____?
• What would happen if ____?
• How would you state ____ in your own words?
• Which statements support ____?
• Do you know of another instance where ____?
• What examples can you think of to support ____?
• How would you use ____?
• How would you solve ____ using what you’ve learned?
• What questions would you ask to better understand ____?
• Why do you think ____?
• What conclusions can you draw about ____?
• Why did ____ changes occur?
• What’s the theme of ____?
• How is ____ similar to ____?
• What’s your opinion of ____ and why?
• How would you handle ____?
• Is there a better solution to ____?
• What information would you use to support the view of ____?
• Why was ____ better than ____?
• Can you see a possible solution for ____?
• What alternative can you propose for ____?
• How would you test ____?
• What would you predict is the outcome of ____?
• What new/unique uses can you come up with for ____?

What to do if students don’t respond to questions

Possibly one of the worst nightmares any instructor can have is asking a question and being met with silence. But with a few simple strategies you can turn silence into learning opportunities:

• Rephrase the question: Chances are your students don’t understand the question or aren’t sure what you’re looking for. In this case, rephrasing the question to clarify could help clear up the confusion. For example, let’s say you ask your students, “How would you define a project?” You can reword the question by asking, “In what ways are projects different from processes?”
• Prompt with information: You might be able to jog students’ memories or thinking by providing information or context. For example, if students cannot answer “How do you calculate the circumference of a circle?” you could break the question down by asking “How do you calculate the radius of a circle?”

Why is it important to use engaging questions while teaching?

At a minimum, crafting thoughtful questions can help you judge whether your class comprehends the concepts presented in the course. Additionally, strategically designing questions can improve students’ learning comprehension by helping them think critically and creatively as well as encouraging them to engage with the course content.

Questions, credibility, and feedback are all aspects of communication that can improve student engagement. A 2021 study published in the Frontiers in Psychology journal found a “strong dynamic between the aspects of academic engagement and teacher caring, credibility, feedback, and communication style.” Additionally, one study participant noted that an instructor’s credibility actually improves if they don’t always know the answers to all questions.

17 effective types of questions in teaching

Planning out your questions for each lesson also involves considering what types of questions you’ll ask. There are numerous question types and each one may elicit a different response from students. Here are some more effective types of questions to use in teaching that encourage critical thinking and creativity:

A type of rhetorical question, display questions help educators check on students’ ability to retrieve information.

• How much of the body’s oxygen consumption does the brain account for?
• Who wrote “The Faerie Queene?”

2. Referential

A referential question is used when the person asking the question doesn’t know the answer. These types of questions may be helpful to instructors when gathering student feedback about course materials and activities—or to create personal connections by checking in on how students are doing.

• Overall, do you feel this class was beneficial?
• How was your weekend?

Factual questions, also called explicit questions, call on students to answer using information pulled directly from reading assignments. Educators can use factual questions to understand whether students understand the concepts presented in the readings.

Factual questions are an essential starting point for students to expand on the information they’ve learned with critical thinking.

• Which art movement is Salvador Dali associated with?
• Who designed the Sagrada Familia in Barcelona, Spain?

4. Convergent

These types of questions ask students to pull together ideas and information from different sources and synthesize them to create a logical answer. Convergent questions are ideal for problem-solving activities.

• What was the common theme in last week’s reading?
• How would you describe this current event in one word?

5. Divergent

The opposite of convergent questions, divergent questions don’t have a single answer. These types of questions are best used to inspire creative responses and encourage students to consider different points of view, ideas, and scenarios.

• How do you think Edgar Allen Poe would have ended “The Tell-Tale Heart” if his main character didn’t confess?
• How do you think the US might be different if the assassination of John F. Kennedy never took place?

6. Evaluative

An evaluative question requires students to think of a response based on their opinion. These questions can prompt students to think critically about readings or discussions and draw connections to their own experiences or ideals.

• What do you think about Captain Ahab’s mission to find the white whale?
• Do you agree with what the author said in this paper about animal rights?

Open-ended questions are essential to prompt students to think critically about their answers. Open questions can’t be answered with a simple “Yes” or “No,” making them a powerful tool for inspiring discussion.

• What is the main purpose of the United Nations?
• What’s one major breakthrough we’ve had in science over the last 10 years?

If instructors are trying to get a student to provide more information about their answer, they can use probing questions to prompt students to clarify, justify, or elaborate on their thoughts.

• What information helped you come to that conclusion?
• Who might disagree with your answer?

9. Multiple choice

One of the most common types of questions, multiple-choice questions provide options for students to choose from when answering. Usually, multiple-choice questions have one correct answer, but alternatives include prompting students to choose the option that’s wrong out of a list of correct options or offering an “All of the above” option.

Multiple-choice questions can improve student participation by making it easier for them to respond. Tech like Poll Everywhere further enhances this accessibility by allowing students to answer using their cell phones—or answer anonymously if the instructor chooses to set up the question that way.

• Which project document includes the description, owner, source, priority, and status of product requirements? a) The project charter b) The requirements traceability matrix c) The scope management plan d) The work breakdown structure
• How are tertiary colors created? a) Mixing equal amounts of two secondary colors b) Mixing unequal amounts of two primary colors c) Mixing three primary colors d) All of the above

Focal questions encourage students to pick a side and support their position with logical reasoning. These can be helpful in inspiring students to consider alternative points of view or schools of thought.

• Do you think all US citizens should have to sign up for the draft? Why or why not?
• Do you believe it was within the right of the US Supreme Court to overturn Roe v. Wade? Why or why not?

Physicist Enrico Fermi is the namesake of the Fermi question, which requires students to estimate an answer based on limited information. You may recognize this type of question from articles covering Google’s unconventional approach to interviewing potential new employees, as Fermi questions require creative thinking and the ability to work through a problem.

• Why are manhole covers round?
• How would you explain how the internet works to a seven-year-old?

Thunk questions are intended to encourage students to pause and look at what might normally be a common, benign concept in a different light. (Fun fact: The term “thunk” is based on the irregular form of the verb “think.”)

• If your pet could talk, what would it say about you?
• What’s the difference between knowing and believing?

13. Hypothetical

Hypothetical questions use the good old “What if…” structure to prompt students to consider a scenario and how they would react or feel. Hypothetical questions inspire creativity, problem-solving, and critical thinking.

• What if Europeans never reached North or South America, how would the world be different?
• What do you think life would be like if dinosaurs never went extinct?

14. Ethical

Educators can present students with moral dilemmas using ethical questions. These types of questions don’t have a right or wrong answer but do require students to think critically about why they believe their answer is correct. Ethical questions are excellent discussion starters.

• Do you think countries should be able to claim other planets as their own?
• Should we take care of workers whose jobs are replaced by AI?

15. Application

Instructors can use application questions to encourage students to apply newly gained knowledge related to the course. By using information they’ve learned in class and applying it to real-world situations, students can achieve a higher level of comprehension.

• What are some examples of media bias you’ve seen recently?
• How would you demonstrate Newton’s first law using objects on your desk or in the classroom?
• Using what you know about cognitive bias, how would you design a website landing page that converts leads?

16. Affective

You can encourage students to engage with course content on a more personal level by using affective questions. These types of questions ask students about their feelings toward a topic and how it relates to their values.

Poll Everywhere’s numeric rating scale allows educators to present affective questions in a friendly way. Ask students to rate how they feel about an issue using a scale from one to five, then ask if anyone wants to chime in with the reasoning behind their rating to kick the discussion off.

• How do you feel about the author’s portrayal of Lenny?
• Is the use of imagination in art important to you?

These types of questions are used to gauge your students’ understanding of a topic all at the same time. By using hinge questions, you can decide whether the day’s class should continue going over the topic or if you can move on to the next lesson.

• Which of the following examples represents an allegory?
• Which of the following is an example of soft news?

3 types of ineffective questions to avoid (or use carefully)

Along with the 17 types of effective questions above, there are three more types of questions that can become problematic if not used carefully.

• Binary: Also called a closed question, a binary question is usually answered with “Yes” or No” or variations thereof. These questions typically force students to choose a side and are more effective if there’s no right or wrong answer or if you probe for additional information.
• Leading: Leading questions are problematic because they suggest the correct or desired answer. An example of a leading question is, “How satisfied were you with the class?”
• Loaded: These types of questions include an implicit assumption about the respondent. An example of a loaded question is, “How many times did you cheat on your exams during the semester?”

Poll Everywhere makes gauging student understanding effective and engaging

Getting students to participate in discussions or even ask their own questions is challenging. Designing effective questions based on your desired outcomes or learning objectives keeps you one step ahead of in-class conversations. However, you should also be ready to guide discussions back on topic if students take off on tangents or a respectful debate becomes a heated argument.

Tech like Poll Everywhere can help you present your questions in an engaging format that invites all students to participate. With the ability to ask and share any type of question using Poll Everywhere, including multiple-choice, you can quickly and easily inspire and guide discussions that all students are excited to participate in.
