How to make a quiz from a lecture video

Most lecture recordings never get revisited after the week they are posted, so a video quiz for students works best when it is built from the same material. DeckOwl does not accept video files directly; paste the transcript, or upload the slides and notes the lecture was based on, and it writes multiple-choice, true/false or short-answer questions with explanations.

Paste a transcript or upload slides, notes, PDF or DOCX files from the lecture
Choose multiple-choice, true/false or short-answer questions
Read the explanation for each answer, including the ones you got right
Retake the same quiz after a few days to check what stuck

Example introductory biology quiz questions

Which organelle produces most of a cell's ATP?Mitochondria. They carry out oxidative phosphorylation, which generates most of the cell's ATP.

True or false: DNA replication is semiconservative.True. Each new double helix keeps one original strand and one newly made strand, as shown in the Meselson and Stahl experiment.

What is the role of mRNA in protein synthesis?It carries the genetic code copied from DNA out of the nucleus to ribosomes, which use it to assemble amino acids in order.

Why do enzymes lower activation energy?They bind substrate at the active site and stabilize the transition state, so the reaction proceeds faster without being used up.

In osmosis, which way does water move across a membrane?From the side with lower solute concentration toward the side with higher solute concentration, because water follows its own concentration gradient.

Answer, check and repeat

Take the quiz, read the explanations for anything you missed, then retake it after a few days.

Quizzing yourself right after watching is one of the most reliable ways to remember what you heard. Short quizzes you retake over several days tend to work better than one long test at the end of the term, because the recall happens again after some forgetting.

Frequently asked questions

How do I study from a lecture video?

Pause at key points and write down the main claims in your own words. Then quiz yourself on those claims before rewatching the parts you missed.

How often should I quiz myself on lecture content?

Take a short quiz soon after the lecture, then repeat it a few days later and again the following week. Spacing the repeats out usually helps more than cramming a single long session.

Can DeckOwl make a quiz directly from a video file?

Not directly. Paste the transcript or upload the slides, notes or PDF from that lecture, and DeckOwl will write the questions from that text.

Which exports are included with each plan?

The free plan lets you study in the browser without exports. Plus adds PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML export.
