The peer rating system used here advances the quantitative literacy goals
outlined in the social sciences. We instituted a mid-semester intervention
to teach rating skills and used an index to track longitudinal changes of
skill mastery over the course of the semester. Seventy-four students in five
advanced research classes followed the procedure of the existing peer rating
system by completing reading assignments, writing reflections online,
engaging in class discussions, rating their peers’ reflections and receiving
feedback on their group effort. Peer ratings were then compared with each
other and also with the instructor ratings to derive individualised indices
of reliability and validity. These technical indicators enabled two rounds
of assessment before and after a class-wide intervention. An omnibus test
across the five classes showed a significant improvement in rating quality
due to the intervention. Our courses not only met a quantitative learning
outcome but also promised vocational competence.
