An in-video quiz is a question or short assessment presented inside the video player at a specified timestamp, typically pausing playback until the learner responds and then either advancing to the next segment or branching based on the answer. Question types range from multiple-choice and true/false to drag-and-drop and short free-text; the first two are the most practical because they can be auto-scored without an AI grading layer. Timing is authoritative: the player fires the question overlay when the video clock reaches the programmed cue point, and the answer is stored with both the question identifier and the video timestamp so analytics can show exactly where in the content comprehension broke down. Results are reported via xAPI using the standard "answered" verb and the result object, or via the SCORM suspend_data field if the LMS is SCORM-only; the xAPI Video Profile provides additional context linking the answer to the playback position. In-video quizzes serve the instructional design principle of spaced retrieval practice: inserting a question immediately after new information is presented forces active recall at the moment of peak salience. The main design gotcha is question fatigue: more than one question every three to five minutes typically degrades the viewing experience without proportional learning gain, so spacing and question count should be calibrated to the learning objective. Automatic quiz generation tools can draft questions from a transcript, but human review remains essential before any question is used for graded assessment.
