This document discusses observation as a research method. It defines observation as having three purposes: to learn, to describe, and to evaluate. There are two types of observation perspectives: descriptive observation, which describes tangible actions, and evaluative observation, which assesses against criteria. Researchers can be participant observers who participate fully or non-participant observers with minimal involvement. Data can be captured in real-time through field notes or with audio/video recording or screen capturing software. Tips are provided for writing detailed, descriptive field notes and developing an observation protocol to focus the observation.
