The effect of marking criteria and exemplars on students' learning during peer- and self-assessment of scientific posters

This case study is the combination of four studies investigating student and tutor perceptions of poster marking criteria at Level 1 undergraduate modules within the general field of Biology. Peer and self-assessment exercises of the students' completed posters together with organised but informal formative feedback sessions were used to provide data concerning students' and tutors' perceptions of marking criteria.
