Classroom observation is a formative process used to gather data on a teacher's performance to provide feedback and inform future development. It has two main purposes - evaluation for administrative decisions, and professional development through continuous quality improvement. The observation process involves a pre-observation conference, the observation itself where an observer quietly takes notes, and a post-observation feedback session. For observations to be effective, the observer must have strong content and feedback skills as well as interpersonal skills and experience with pedagogy.
