Two Studies of the Rating Process

Location: Seminar Room D, Department of Education
Due to the subjective nature of human decision in the context of the marking of constructed response assessment items, those who administer marking projects are interested in identifying best practices with the goal of making the training and marking processes quicker without reducing marking accuracy.
In this presentation, I summarize two studies designed to inform those decisions. In the first study, I conducted an experimental study in which markers were assigned to one of three groups who received different amounts of marking practice during marker training, and I measured the impact of these varying levels of practice on marking accuracy and speed. In the second study, I conducted secondary data analysis in which I regressed textual features of essays (e.g., development, organization) onto measures of the difficulty markers had assigning accurate scores (i.e., a measure of the average distance of marks from an expert consensus score).
