Inside TFA

Teachers have to put lesson plans in these big binders and set them in a noticeable area of their classrooms so that observers and higher-ups can flip through to the lesson plan being given on that day and key in on the teacher's thoughts and methodologies while watching that teacher perform his/her lesson even though teachers (or at least THIS TEACHER) happens to write a lesson plan and revise it ten times before the lesson ever makes it to the front of the classroom.
Despite this fact, the unnamed "they" still want that lesson plan in that binder in that area of the classroom so that "they" have the security of knowing the secret failures and foibles of the teacher as he/she stands in front of the room of wide-eyed students and promptly forgets the lesson plan so neatly tucked in the binder.
Thus, it is a mere statement of the obvious to say that while this process allows observers a great deal of security, it dooms the teacher to continual insecurity because "they" know everything that you are not doing because everything changes as soon as you begin doing it.

The "they" say that it is to assure preparation.

I say that the BINDER is the MAN. I know the MAN. Do you?
