Timed Video Quizzes

Pause a video at a chosen moment and ask the learner a question before playback resumes — checkpoints that keep attention on long videos and prove the material was watched, not skipped.

Timed Video Quizzes

A timed video quiz is a checkpoint inside a video. At a moment you choose, playback pauses and the learner answers a question before it resumes. It turns a video from something that can be left playing in another tab into something that has to be watched.

These are part of the video itself, not a separate lesson. There is nothing to add to your curriculum — you configure them on the video content you already have.

Use a timed video quiz to keep attention inside a video, and a quiz or assessment to measure what somebody learned. A checkpoint is not scored toward a course result and does not produce a mark — if the answer needs to count, use an assessment.

Adding a checkpoint

Open the video in your course's curriculum builder and find the timed-quiz section.

For each checkpoint:

  1. Set the timestamp — the point, in seconds, where playback should pause.
  2. Optionally give it a title, shown on the overlay (Checkpoint 1, Before we move on).
  3. Add one or more questions.

For each question:

  • the question text;
  • 2 to 6 answer options, none of them blank;
  • which option is correct;
  • optionally feedback shown after a correct answer, and after an incorrect one.

Put a checkpoint just after the point you want remembered, not on top of it. A question at 2:00 about something explained at 1:58 reads as a test of attention; the same question at 1:58 interrupts the explanation.

Checkpoints are re-ordered by timestamp automatically, so you can add them in any order and the list sorts itself.

What the learner sees

Playback reaches the timestamp and pauses. The question appears over the video, the learner picks an answer, and it is checked immediately — with your feedback text if you wrote one. Then the video resumes.

Learners are also told in advance that a video has checkpoints, so pausing part-way through does not read as a fault in the player.

Answers are never sent to the browser. The correct option and both feedback texts are stripped from the payload the learner's player receives, and each answer is checked on the server as it is given. A learner cannot read the answers out of the page source — which is exactly why checkpoints are worth using on content that matters.

Each answer is recorded against the learner's progress, along with how many attempts they took. That is what lets you see a checkpoint that everybody fails — usually a sign the video is unclear at that point rather than that the cohort is weak.

Editing a video that already has checkpoints

Checkpoints are configuration of the video, so editing them does not disturb the video file, its streaming or its progress records. You can add, reword and re-time them on published content.

Re-cutting the video file does not move the checkpoints. Timestamps are absolute seconds into the video, so trimming 10 seconds from the opening shifts every checkpoint 10 seconds late relative to the content. After replacing a video, re-check the timestamps.
