Retrieval practice with live quizzes: a practical lesson plan

Write down what a learner should be able to do after the session. “Understand ratios” is broad; “scale an ingredient quantity when the number of portions changes” gives you a question to design. Keep the target narrow enough that you can discuss the reasoning behind an answer. A short round with a clear purpose is easier to act on than a long collection of unrelated facts.

The Institute of Education Sciences practice guide recommends spacing learning, using quizzes to revisit key content, and asking explanatory questions. It also recommends using quizzes to identify material that needs further study. These are teaching principles, not evidence that a particular app or a particular five-question round guarantees a learning improvement.^[1]

For a first round, try one recall question, two questions that use the idea in a situation, and one question about a likely misconception. That mix is a suggested starting point, not a prescribed research-tested formula. Use material you have taught or clearly explain when a question is an introduction to something new.

• Recall: identify the meaning of a ratio before doing a calculation.
• Application: scale the quantities in a recipe with the same proportions.
• Misconception: distinguish multiplying every quantity by the same factor from adding the same amount.

A multiple-choice response shows which option a learner selected. It does not automatically show how they produced the answer. Carnegie Mellon’s assessment guidance distinguishes recognizing an argument from articulating one. Add a spoken, written, or paired explanation when reasoning is your actual learning target.^[2]

Before the round, write a brief explanation for each incorrect option. Keeping the original quantity ignores the change in portions. Two cups scales to eight portions. Twelve cups confuses a portion count with a water quantity. These interpretations are hypotheses to discuss; a selected option alone cannot tell you what a particular learner was thinking.

• Ask: “What changed between the two recipes, and what stayed the same?”
• Invite someone to show the scale factor without naming a learner who answered incorrectly.
• Follow with a different portion count so learners use the relationship again.

Explain the purpose before players join: this is a chance to practise and find questions, not a judgment about who is clever. Include a simple practice item so people can try the joining and answer flow. Choose a timer that allows reading, thinking, and operating a device. OpenQuiz supports 5–300 seconds per question, but an available setting is not evidence that it meets every access need.

1. Give the group a clear instruction about whether to work individually or discuss before answering.
2. Let learners attempt the question before you explain the correct answer.
3. Use End Question to show results without moving immediately to another question.
4. Discuss the key idea while the results are visible, then use Next Question when ready.
5. If the format excludes someone, arrange an appropriate alternative rather than treating the timer as a learning objective.

Use a later round to revisit the same concept with new surface details. Repeating only an identical question can let someone remember a position or a phrase instead of the relationship you want them to use. The IES guide supports reviewing key content after a delay; it does not give one universal interval that will suit every learner, subject, or course.^[1]

Keep your schedule realistic. Revisit the material within a sequence of teaching rather than creating a separate quiz administration burden. If learners have not had an opportunity to learn or practise the idea, use the result to plan instruction instead of interpreting it as a failure to remember.

After a round, note which idea needs attention and one change you will make. For example: “Several answers kept the original water quantity, so I will model the scale factor with a drawing.” A correct answer may reflect knowledge, a useful strategy, a guess, or recognition of a clue. Likewise, a missed answer may reflect wording, timing, access, or content understanding. Ask a follow-up before deciding which explanation fits.

• If a misconception appears common, explain the contrast between the correct and tempting incorrect answers.
• If a question is ambiguous, acknowledge it and revise it before using it again.
• If the group answers correctly, ask learners to explain or apply the idea in a new situation.

OpenQuiz includes timed scoring, so speed can affect the leaderboard. Use the discussion and follow-up task alongside the selected answers when making teaching decisions. This kind of low-stakes quiz is one piece of evidence; it is not, by itself, a complete assessment of understanding.
