| Sintesi≠ | 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. | Value-added teacher evaluation uses longitudinal student test scores to estimate how much individual teachers contribute to their students' achievement growth, net of what students brought into the classroom. Statistically it applies value-added and mixed-model machinery — controlling for prior achievement and student characteristics, then treating each teacher's residual contribution as an effect to be estimated. Pioneered in Tennessee's TVAAS and scrutinized in a large methodological and policy literature, it became central, and controversial, in teacher accountability. |
