Video lesson

{{Short description|Video presenting educational material}}

A video lesson or lecture is a video which presents educational material for a topic which is to be learned.

The format may vary. It might be a video of a teacher speaking to the camera, photographs and text about the topic or some mixture of these. Animated video lessons, in particular, use engaging visuals and simplified explanations to help break down complex topics, making them especially effective in subjects like Science or Math.{{Cite web |date=2024-09-26 |title=Struggling to Keep Students Engaged?

These were then loaded onto YouTube where they have been popular and influential. Such lectures are a key part of flip teaching in which the initial work of communicating the essentials of the topic is done by the video lesson.{{citation | url=http://www.economist.com/node/21529062 | newspaper=The Economist | title=Flipping the classroom | date=17 Sep 2011}}{{citation | url=https://reviewshost.com/video-in-the-class-keeps-savvy-students-engaged/ |title=Video in the class keeps savvy students engaged |author=Diana Mehta |journal=The Canadian Press | date=8 Sep 2011}}{{citation | url=https://reviewshost.com/flip-thinking-the-new-buzz-word-sweeping-the-us | journal=The Daily Telegraph | date=12 Sep 2010 | author=Daniel Pink | title=Flip-thinking - the new buzz word sweeping the US}}

A study shows that there is hardly any difference in correctly answered questions when students were divided into two groups that used either live lecture or video lecture.{{cite journal |last1=Brockfeld |first1=Thomas |last2=Müller |first2=Bringfried |last3=de Laffolie |first3=Jan |title=Video versus live lecture courses: a comparative evaluation of lecture types and results |journal=Medical Education Online |date=17 December 2018 |volume=23 |issue=1 |doi=10.1080/10872981.2018.1555434 |pmid=30560721 |pmc=6300084 }} But there were some differences in subjective evaluation: 48% of students preferred live lessons, 27% preferred video lessons and 25% stated ‘neutral’.

Another meta-study {{cite web | website=psyarxiv.com | date=2019-01-01 | url=http://psyarxiv.com/kynez | access-date=2023-04-10|title=Video improves learning in higher education: A systematic review}} investigated more than 100 studies and find out that about 75% of the time, students learned better from the video. On average, the effects are small (about +2 marks) but consistently favour videos. Effects are much larger when videos replace books (+7 marks), or when videos are used to teach skills (+6 marks) instead of knowledge.
