Human Beings Not As Impressive As You Think

A recent study suggests that computers can score student essays about as well as human beings. Les Perelman, a director of writing at MIT, isn't impressed: While his research is limited, because E.T.S. is the only organization that has permitted him to test its product, he says the automated reader can be easily gamed, is vulnerable to test prep, sets a very limited and rigid standard for what good writing is, and will pressure teachers to dumb down writing instruction. The e-Rater's biggest problem, he says, is that it can't identify truth. He tells students not to waste time worrying about whether their facts are accurate, since pretty much any fact will do as long as it is incorporated into a well-structured sentence. "E-Rater doesn't care if you say the War of 1812 started in 1945," he said.
