Video lesson is a format of distance learning that involves delivering educational material through video recordings at any convenient time for learners. This recording can be a simple lecture, a demonstration of practical skills, a presentation with the author's commentary, or a screen recording of a specialist teaching how to work with software.
Advantages of video lessons as educational material:
The video format allows delivering the maximum amount of information in minimal time. This makes it convenient and understandable for learners. They can simultaneously watch what the lecturer is doing, listen to him, and read additional notes. If they get distracted or do not understand something, they can simply rewind and rewatch the unclear part.
When learning through video lessons, the learner does not need to read much or constantly focus on the audio lecture. They can watch lessons on their way to work or from a break room without reducing learning quality.
Video can show things that are too difficult to explain verbally. For example, training to work with complex software is better conducted through screencast lessons — recordings of the teacher’s screen with commentary. Some practical skills develop better when the student sees an example. Additionally, during video editing, important points can always be visually highlighted or emphasized, and good design keeps the learner's attention on the lesson.
