The document discusses top-down and bottom-up approaches to curriculum development and maturing. Traditionally, standards are developed top-down but courses can evolve standards bottom-up by incorporating new knowledge and competencies. Curricula can mature through bottom-up contributions from courses that help standards evolve. Semantic mapping of curricula, standards, competencies, activities and assessments allows for academic analytics and formative evaluation to support ongoing curriculum improvement through bottom-up and top-down processes.
