A Study in Self‐assessment: tutor and students’ perceptions of performance criteria

ABSTRACT This paper reports a study which implemented and evaluated a method of student self‐assessment. The theme of the importance of marking criteria (Orsmond et al., 1996) is developed. Pairs of first‐year undergraduate biology students were asked to complete a poster assignment on a specific aspect of nerve physiology. The study was designed to allow the evaluation of (1) student self and tutor marking for individual marking criteria; and (2) student vs student marking of their poster work for individual marking criteria. A comparison between the tutor and the student self‐assessed mark reveals how important it is to consider the individual marking criteria rather than the overall mark. These results support our findings on peer assessment reported earlier (Orsmond et al., 1996). The results also illustrate the potential pitfalls that exist when making assumptions about the degree of student/student interaction and students’ marking ability. This study supports previous work which showed that self‐assessment is extremely useful in helping students reach their learning goals, i.e. it is a strong formative educational tool and can be used in order to bring about behavioural changes in students with regard to their own learning processes.
