Can computers really grade essay tests? The National Council of Teachers of English say “no,” even if there is new software that says “yes,” the Washington Post reports. New software described in this New York Times story allows teachers to leave essay grading to the computer. It was developed by EdX, the nonprofit organization that was founded jointly by Harvard University and the Massachusetts Institute of Technology and that will give the software to other schools for free. The story says that the software “uses artificial intelligence to grade student essays and short written answers.”
