Using a linguistic scorecard for peer-assessment through an on-line system - Multiple criteria multiple peer-assessment with linguistic inputs

摘要

Peer-assessment is a way to include evaluation as a part of the learning process and simultaneously to cut teacher load in grading of assignments. E-Learning systems can be used to automate peer-assessment to a large extent. Peer-assessment benefits from multiple-peer-assessment as it is likely to even-out outliers. Linguistic scorecards can be used to simplify assessment. The linguistic scales can be mapped to fuzzy scales and the results weighted and aggregated to derive an overall assessment. Sometimes ranking of the outcomes is needed. This paper presents the foundations of a system that uses linguistic scorecards in peer-assessment that uses self-evaluation in weighting results, and that ranks the assessments. A numerical example is used to illustrate the system.
