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

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.
