Tóm tắt	A classroom observation protocol is a standardized instrument for measuring teaching by having trained observers rate lessons against defined dimensions of practice. Unlike informal walkthroughs, validated protocols such as the Classroom Assessment Scoring System (CLASS) and the Danielson Framework specify what to look for, how to score it, and how to train and calibrate raters. As Pianta and Hamre argued, standardized observation turns teaching into something that can be measured systematically, studied for sources of error, validated against student learning, and used to improve instruction.	Generalizability Theory is a psychometric framework that decomposes observed score variance into multiple sources — persons, items, raters, occasions, and their interactions — using analysis of variance. It replaces the single reliability coefficient of classical test theory with a family of coefficients that tell researchers how well scores generalize across different measurement conditions.
