I did a classroom observation on two high school classrooms. They were as different as night and day. My instructor has asked me to review the field notes I collected for the "Classroom Observations". I need to develop a coding system for my observation notes. He instructed us that as I work on my codes, be sure to consider the broad research problem stated in the Classroom Footage Observation Field Note Guide:This is the problem "What is the nature of the interactions in these settings"?

My initial posting should consist of a list of the codes I should develop for my observation notes.

The class room that I observed were high school classrooms and one teacher was very verbal and the other was rather quiet. She basically walked around and looked over the students shoulder as they di their assignments from the black board. She would stop now and then and talk to some students.

I don't have any idea where to start and how to develop a code for a observation. Please help.
