I am very fortunate to be part of a school that utilizes its instructors to assist with the creation, development and ongoing "upgrades" to its day to day lesson plans and course information. Our school understands that WE are the people using it everyday. We even involve the students in an indirect fashion.
We, as instructors still plan our daily lessons and meet to go over the days results to determine what worked, what didn,t and what can we do better. Our main goal is consistency of the lesson no matter who teaches it
