Homework is important for several reasons: it allows students to review and practice what they learned in class, prepare for the next day's lessons, explore subjects more fully, and extend their learning by applying existing skills to new situations. When assigning homework, teachers should establish clear guidelines about purpose, amount, and expectations. They should also provide feedback to students to enhance learning and achievement. Research shows that mastering skills requires focused practice over time with opportunities for students to deepen their understanding of concepts and receive feedback on their progress.
