I remember filling a thick folio with lesson plans. Heavy to carry. WE were told to be devotees of the LP by the University. At the end of the course, I asked my supervisor if he wanted to see them. His answer? WE don't need to see your lesson plans. That was for your purposes. If I could have smashed him over the head with the LP folder and got away with it at that time!!
Having worked as a teacher, you only need a small handbook for a LP and, in time, it can all be done in your head. It becomes automatic. Like driving a car or riding a cycle.
The structure of a LP is cyclical, e.g. LP1
1. learning aims/goals/objectives
2. teaching techniques and methods to deliver [1]
3. Resources required to deliver [1]
4. Assessment/evaluation/marking : have the learning objectives been achieved?
Yes? to LP2
No? return to and recapitulate LP1. etc, etc
