The document discusses approaches to curriculum management. It describes Deming's model of plan, do, study, act as a preferred approach that requires constant evaluation, implementation, attention and research. This collaborative model uses data-driven decision making at each stage of planning, doing/studying, and acting. In contrast, some schools manage curriculum in isolation without input or research. The document advocates using Deming's model to develop curriculum, gathering data, involving stakeholders, examining implications, and connecting the curriculum to the school's overall philosophy before implementation. Curriculum mapping is also discussed as a grassroots method that promotes consistency, removes top-down control and builds collaboration.
