This document provides guidance on how to write effective field notes for ethnographic research. It discusses that field notes should be written as soon as possible after leaving the field site to capture important details while memories are still fresh. Field notes should include specifics like dates, times, locations, sensory impressions, conversations, and questions for further investigation. There are four main components of field notes: jottings taken in the field, descriptive observations, analysis linking observations to research questions, and personal reflections. The document provides examples of annotated field notes to illustrate how these different components can be separated and organized.
