خلاصه	Opportunity to learn (OTL) analysis measures the degree to which students are actually taught the content on which they are assessed, and relates that exposure to their achievement. Rooted in Carroll's 1963 model of school learning and developed as both a research concept and a policy instrument by McDonnell (1995) and the international IEA assessments, it treats content coverage, instructional time, and the alignment between the enacted curriculum and the tested curriculum as measurable conditions of learning rather than properties of the learner.	Educational growth curve modeling is a longitudinal multilevel technique for describing and explaining how individual students change over time on an outcome such as reading or mathematics achievement. Building on the hierarchical linear models framework formalized by Bryk and Raudenbush (1987) and the applied longitudinal treatment of Singer and Willett (2003), it fits each student a personal trajectory — an intercept and one or more slopes — and then models how those personal growth parameters vary across students and relate to learner characteristics, classrooms, and schools.
