Peer assessment plays a vital role in student learning as it encourages critical evaluation of classmates' work, enhancing understanding of subject matter. By reviewing peers' assignments, students can gain different perspectives and insights that deepen their own learning. This collaborative approach also fosters essential skills such as communication, feedback delivery, and constructive criticism. Furthermore, engaging in peer assessment promotes a sense of responsibility and accountability, making students more aware of the standards expected in their own work, thereby improving overall academic performance.
