Lesson

A lesson or class is a structured period of time where learning is intended to occur.

[citation needed] It involves one or more students (also called pupils or learners in some circumstances) being taught by a teacher or instructor.

In a wider sense, a lesson is an insight gained by a learner into previously unfamiliar subject-matter.

A lesson may range from a lecture, to a demonstration, to a discussion or a blend of some of these common presentation methods.

For example: film strips, pre-recorded audio and video tapes, television programs and podcasts are some ways to deliver or add to a lesson.

The expectation is that the teachers can and should depart from the script when appropriate; improvisation is definitely encouraged and the fact of having written it out in advance ensures that an adequate amount of thought has been put into it ahead of time.
