Homework is used in education for numerous reasons, but a primary one for K-12 students is to involve parents in a child's learning. Homework also gives students a chance to practice and apply concepts learned at school or to prepare for optimal learning in upcoming classes.
Studies show that kids perform much better academically when their parents actively engage in their learning experience, according to Scholastic. When teachers send homework home with kids, parents get a chance to see what students are working on and to show emotional and instrumental support to the learning process.
Teachers have different strategies with homework. Some want students to apply concepts learned in class actively to create higher-level learning. Others use homework as a review or learning tool to enable students to prepare for additional activities and projects in class, where teachers can supervise. In the big picture, the intent of homework is to optimize a student's learning and knowledge acquisition.
An intangible benefit of homework is that students learn self-discipline, time management and other important life skills. Students are accountable for getting homework assignments completed and turned in on time. The resulting grade and feedback reinforces responsible decision-making, and constructive feedback helps students learn to develop more beneficial habits.
