Answer 1

Answer:

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. The Khan Academy has been successful in teaching mathematics using notes written using Yahoo!'s doodle pad with a voiceover by Salman Khan (educator).
