I am teaching an online class, so i must compile the materials by myself. But i can not make up my mind whether i should use "unit" or "lesson" to introduce my teaching content . Can you tell me the difference between them?
Thanks in advance!
A unit, depending on its length and topic, could take one lesson (i.e., one class lecture) to finish, or several lessons, or more. A unit is like a chapter of a book. It houses a specific topic.
Does that help?
