Teacher supported peer evaluation through openanswer: A study of some factors
In the OpenAnswer system it is possible to compute grades for/to the answers to open-ended questions given to a class of students, based on the students’ peer-evaluation and on the teacher’s grading work, performed on a subset of the answers. Here we analyze the systems’ performances, expressed as the capability to infer correct grades based on a limited amount of grading work by the teacher.
