The document discusses formative and summative assessment. Formative assessment is used to provide feedback during instruction to improve student learning and teaching, such as oral questions, drafts, and peer reviews. Summative assessment evaluates learning at the end of an instructional period through tests and projects. The key purposes of assessment are to promote student learning, measure achievement, and inform instructional improvements. Assessment should involve setting goals, rich feedback conversations, and active student involvement in the learning process.
