The FT2T approach to lesson planning is a good example of producing a plan close to the point of use.
In FT2T lesson planning takes place using the Presentation eg PowerPoint which will be used in the lesson. Instead of writing on a piece of paper, or on a form something like...
Starter
Seating Plan
Lesson Objectives
Register
Teacher Explanation
Activity
Etc
... a teacher should type them directly into the PowerPoint presentation that they will use in the lesson (hiding any aspects which do not need to be seen by students)
