The interest of using automatic tools by human beings has been increased. We'll continue to see year after year companies putting out PR to claim they've totally got this under control, but until they can put out a working product, it's all just a dream.Assessment is considered to play an essential function inside the Educational System.

In states like Utah and Ohio where it is being used, we can expect to see more bad writing and more time wasted on teaching students how to satisfy a computer algorithm rather than develop their own writing skills and voice to become better communicators with other members of the human race.

In other words, rather than trying to make software recognize good writing, we'll simply redefine good writing as what the software can recognize.Ĭomputer scoring of human writing doesn't work. Says the senior research scientist at ETS, " If someone is smart enough to pay attention to all the things that an automated system pays attention to, and to incorporate them in their writing, that's no longer gaming, that's good writing." That's underlined by a horrifying quote in the NPR piece. And the people selling this baloney can't tell the difference themselves. Students can rapidly learn performative system gaming for an audience of software. The point is that their inability to distinguish between good writing and baloney makes them easy to game. The point is not that robo-graders can't recognize gibberish. The unhappy lesson there is that the robo-graders merely exacerbate the problems created by standardized writing tests. The secret of all studies of this type is simple- make the humans follow the same algorithm used by the computer rather than he kind of scoring that an actual English teacher would use.

The full dismantling is here, but the basic problem, beyond methodology itself, was that the testing industry has its own definition of what the task of writing should be, which more about a performance task than an actual expression of thought and meaning. Perelman tore the study apart pretty thoroughly.
Robo-scoring fans like to reference a 2012 study by Mark Shermis (University of Akron) and Ben Hamner, in which computers and human scorers produced near-identical scores for a batch of essays. More recently, the former MIT professor teamed up with some students to create BABEL, a computer program that can create gibberish essays that other computer programs score as outstanding pieces of writing.
He was going hand-to-hand against the "new" SAT writing portion over a decade ago with a 5/6 essay about how Franklin Delenor Roosevelt fought the communists in 1930. The king of robo-score debunking is Les Perelman. He pulled up a letter of recommendation he had written, replaced the student's name with words from a Criterion writing prompt, and replaced the word "the" with "chimpanzee." Criterion gave the resulting essay a 6 out of 6. Back in 2007, writing instructor Andy Jones (University of California-Davis) decided to test Educational Testing Service's robo-grader Criterion. So much for open-ended questions and divergent thinking.īut the biggest problem with robo-grading continues to be the algorithm's inability to distinguish between quality and drivel. The second is that this narrows the AI's view by saying that a good essay is one that looks a lot like these other essays. The first is that somebody has to pick the 100 exemplars, so hello again, human bias. Is punctuation not important, a little important, or super-important? You'll have to tell the program which judgment to follow, and the moment you do, you've embedded one of your personal biases into the machine.įans of robo-graders like the one in the NPR piece talk about how the AI can "learn" what a good essay looks like by being fed a hundred or so "good" essays. You cannot write the program without first making your own judgment about what constitutes good writing. This is particularly true for programming that scores something as subjective as writing. Only two of these are correct computer software, even Artificial Intelligence, is an encoded version of human biases. Right off the bat, Tovia Smith offers three advantages of robo-grading: cheap, quick and without human bias.
