The document discusses the influence of contextual variables on academic performance. It outlines four predictive models used to explain academic performance: the psychological, sociological, psychosocial, and eclectic interaction models. Contextual variables that potentially impact school performance are analyzed at the macro- and micro-sociological levels. Examples of contextual variables identified include social class, cultural resources, economic income, parents' educational levels, type of school, and classroom dimensions. The relationships between these contextual variables and performance measures are then analyzed.
