We've talked in the past about the ability of artificial intelligence to evaluate student performance. "It is believed that artificial intelligence technology can almost completely replace the teacher as the system has a built-in assessment function," write the authors. But should it? This paper (15 page PDF) raises a new question: what is the influence of automated assessment, as compared to the more human version? The study, though small, looked at students in I.M. Sechenov First Moscow State Medical University in Russia and Wuxi Institute of Technology in China. One group took formative tests assessed by a computer system, the other took the same type of tests on paper and assessed by a teacher. Formative evaluations were higher using automated systems, and correspondingly, those using automated assessments did better on summative evaluations as well. The authors suggest the effect is caused by the immediacy of feedback from automated assessment. That said, the differences are small, and not always consistent, and dwarfed by the effect of individualized instruction.
