Why a quiz beats rewatching the video

A lecture video is easy to watch and hard to recall later, so a video to quiz step turns it into practice you can do the same day. Paste the transcript or your notes and DeckOwl writes questions from what the material actually covers.

  • Works from transcripts, slides, PDFs, DOCX files and photos of pages
  • Multiple choice, true/false and short answer questions
  • Every question includes an explanation of the correct answer
  • Free plan includes 3 generations per month and browser study
Example ecosystems and food webs quiz questions
In a food web, what do the arrows point toward?The direction energy moves, from the food source to the organism that eats it, because arrows show energy flow.
True or false: energy is recycled through each trophic level.False. Energy is lost as heat at each level, so only a fraction passes on, while nutrients like carbon cycle through the ecosystem.
Why are there usually fewer top predators than primary producers?Energy is lost at each trophic level, so less energy is available to support each higher level.
What is a keystone species?A species with a disproportionately large effect on its ecosystem, because removing it can change the whole food web that others depend on.
Which organisms are the primary producers in most terrestrial food webs?Plants and other photosynthetic organisms, because they convert sunlight into chemical energy that the rest of the web depends on.

Answer in the browser and read the explanation for every question.

Short answer questions make you explain an idea in your own words, while true/false questions catch common misconceptions. Each question comes with an explanation, so a wrong answer teaches you something.

Quizzes work best when you retake them after a gap. Generate a fresh set from the same source later in the week to test what stuck.

Frequently asked questions

How many questions should a quiz on one video have?

Ten to fifteen questions usually cover a single 10 to 20 minute lecture well enough to reveal gaps. Mixing true/false with multiple choice practices both recognition and recall.

What should I test on a lesson about food webs?

Focus on who eats whom, the direction energy flows, and what happens to populations when one species is removed. Short answer questions work well for explaining why energy shrinks at each trophic level.

Can I export the quiz?

Export is a paid feature. Plus includes PDF, DOCX, Anki and CSV, and Pro adds QTI 2.1 and Moodle XML.

Do I need a credit card to start?

No. You can start on the free plan with 3 generations per month and study in the browser. Students get 40 percent off with a school email.
