Homework has four basic purposes: Practice (e.g., after the teacher has directly taught a math algorithm in class, the homework is to complete several problems requiring use of that algorithm). Preparation (e.g., pre-reading or looking over a new unit of study in a text for the next class meeting). Study (e.g., reviewing content to prepare for a test). Extend or elaborate (e.g., completing a project or paper on a topic such as investigating the causes of the Vietnam War).
