| Resum≠ | An opportunity-to-learn (OTL) index quantifies how much exposure students have had to the content and instructional resources they need to succeed on an assessment. Rooted in Carroll's model of school learning and developed through the IEA international studies, OTL measurement asks whether students were actually taught the material before being tested on it. Constructed from teacher reports, curriculum analysis, or instructional logs, OTL indices are used both as a fairness criterion for interpreting test scores and as a policy instrument for monitoring equitable access to the intended curriculum. | 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. |
