Peer assessment
It's a powerful way for your students to act as the 'assessor' and to gain an opportunity to better understand assessment criteria It can also transfer some ownership of the assessment process to them, thereby potentially increasing their motivation and engagement. In doing so, your students might be encouraged to learn more deeply, building up their understanding, rather than just their knowledge of the facts, as well as gaining an insight into their own approach to an assessment task in comparison to their peers. Peer assessment is particularly useful in aiding your students to develop judgment skills, critiquing abilities and self-awareness.
