Annie-Murphy Paul wrote an interesting piece on robo-graders for assigning grades and test scores.Yep, it means computers checking papers and tests. While many people are against it, she describes an unexpected benefit what could be called the “disinhibition effect” :

“Instructors at the New Jersey Institute of Technology have been using a program called E-Rater in this fashion since 2009, and they’ve observed a striking change in student behavior as a result. Andrew Klobucar, associate professor of humanities at NJIT, notes that students almost universally resist going back over material they’ve written. But, Klobucar told Inside Higher Ed reporter Scott Jaschik, his students are willing to revise their essays, even multiple times, when their work is being reviewed by a computer and not by a human teacher. They end up writing nearly three times as many words in the course of revising as students who are not offered the services of E-Rater, and the quality of their writing improves as a result. Crucially, says Klobucar, students who feel that handing in successive drafts to an instructor wielding a red pen is “corrective, even punitive” do not seem to feel rebuked by similar feedback from a computer.”

She concludes that working with a computer could help loose anxiety about learning.
