Overview
Oftentimes, the most efficient way to learn more about advanced writing (and researching) in a discipline is to look at good models. These models can be from publications (i.e., reading what's already out there). However, it's sometimes even more useful to read the writing of other graduate-level students.
Annotated Sample Student Paper
Follow the link below to read a sample paper from another graduate student in your field. This annotated MA project paper in the area of Teacher Education is a superb example of action research/autoethnography. (Note that it is 60+ pages in length, which is significantly longer than the typical MA project paper in the Teacher Education Department; however, it does an excellent job of being illustrative of the genre.)
