The document discusses the CIPP model for curriculum evaluation developed by Daniel Stufflebeam. The CIPP model guides evaluators and stakeholders in systematically assessing a curriculum at four stages: context, input, process, and product. Context evaluation involves analyzing needs and goals. Input evaluation considers resources and design. Process evaluation monitors implementation. Product evaluation judges outcomes against anticipated results to determine if the curriculum should continue, be modified, or discontinued. The model helps answer four questions: what should we do, how should we do it, are we doing it as planned, and did the program work.
