This document outlines principles and best practices for classroom observation by supervisors. It discusses that the goal of observation is to help improve teaching and learning, not to evaluate teachers. Supervisors should enter and exit classrooms quietly without disruption, focus on key aspects of the lesson, and provide constructive feedback to help teachers. They should consider child development, effective teaching methods, and democratic practices during observations. The feedback session with the teacher should be a cooperative discussion to further support quality education.
