Writing Decisions

I am working on writing now and running into some difficulty. I am trying to combine anecdotes from my time spent at Wright Elementary with research I have done. So far I am intertwining the two as I write. I can't decide if it would be more beneficial to begin the paper with an overall description of all my observations, or describe as they apply to my research. I am also considering breaking the paper into sections, with a relevant description from Wright at the begining of each. Any thoughts on structure would be helpful.
