The ability of a teacher to draw a difference between a lesson plan and a lesson is very important,

A lesson plan is a procedure document for the teacher. In this document the teacher has placed his or her wishes for the lesson but they are just wishes.

A lesson is the presentation that delivers the lesson to the learner. its the actual document the learner will experience in class.

And at this point is where lesson notes become important and lesson presentations like power point become of valuable use in the lesson.

This distinction will make you a teacher of excellency.
