Analysis of the Validity of E-assessment and Self-Assessment in Formal Assessment in Electrical and Electronics Engineering Studies through a Case Study

摘要

A case study about the validity of e-assessment and self-assessment in Electrical and Electronics Engineering studies is presented. The results show that the students are able to assess and grade their own work in a quite similar way than instructors do: high correlation coefficients, low differences between their marks and the instructors' marks comparable to those found among different instructors, no statistically different means and standard deviations, and comparable effect sizes with respect to those found among instructors. However, a relatively large number of students took advantage of the process and over marked their work. This group of students obtained surprisingly high scores in a series of e-assessed tests delivered by a learning management system. So an additional control is necessary to avoid this unfair behavior.
