This document discusses formative and summative evaluation in curriculum development. Formative evaluation is used during curriculum development to identify areas for improvement, while summative evaluation is used at the end to judge the overall effectiveness of the curriculum. Formative assessment is used to check student understanding along the way and provide feedback, while summative assessment serves as an end survey to collect data and analyze learning outcomes. Both formative and summative assessments are widely used in education to monitor progress and make decisions about curriculum.
