The document summarizes the conceptual landscape of educational leadership through different epochs of modernism. Modernism still dominates educational leadership discourse and is characterized by rationality, science, and objectivity. Key epochs discussed include the pseudo-scientific era of Taylor's scientific management focused on efficiency; the early scientific era emphasizing administration functions; behaviorism viewing actions as stimuli responses; structuralism studying organizational structures; feminist/critical theory challenging traditional roles; and later developments like critical race theory, queer theory, and postmodernism questioning modernist assumptions.
