THE WAR ON UNIONS:

Why Students Prefer to Learn From a Machine : Robo-readers aren't as good as human readers--they're better (Annie Murphy Paul, 8/14/14, Slate)


[T]here's another use for robo-graders--a role for them to play in which, evidence suggests, they may not only be as good as humans, but better. In this role, the computer functions not as a grader but as a proofreader and basic writing tutor, providing feedback on drafts, which students then use to revise their papers before handing them in to a human.

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.
