Grading Software Fooled By Nonsense Essay Generator 187

An anonymous reader writes "A former MIT instructor and students have come up with software that can write an entire essay in less than one second; just feed it up to three keywords.The essays, though grammatically correct and structurally sound, have no coherent meaning and have proved to be graded highly by automated essay-grading software. From The Chronicle of Higher Education article: 'Critics of automated essay scoring are a small but lively band, and Mr. Perelman is perhaps the most theatrical. He has claimed to be able to guess, from across a room, the scores awarded to SAT essays, judging solely on the basis of length. (It’s a skill he happily demonstrated to a New York Times reporter in 2005.) In presentations, he likes to show how the Gettysburg Address would have scored poorly on the SAT writing test. (That test is graded by human readers, but Mr. Perelman says the rubric is so rigid, and time so short, that they may as well be robots.).'"

    I though most schools don't even care about the essay. Also the elite schools nowadays prefer the ACT and SAT II subject tests to demonstrate real knowledge. The SAT is really a dumb test, especially with all the coaching resources available now.

        It's swung so far the wrong way that in many places, aggressive parents are required to get the minimum education proscribed by law. If you don't have active parents, the school actively punishes the children. The thought is that they are already failures because of their parents, so better to get them used to failure and hope they drop out, so as not to harm the schools statistics.
      • I feel like the pendulum is starting to swing entirely too far the other way.

        What we have here is a superposition of extreme pendulum states.

        (Actually, no: we simply have multiple pendulums at opposite extremes. However, calling it a "superposition" is more fun!)

  • Since the essays are grading subject knowledge, and it takes subject knowledge to provide the keywords, it is fairly irrelevant if the essay happens to be structured in a manner that is nonsensical.

    Demonstration of deeper understanding, if it needs to be tested, can be achieved via other types of questions.

    • The next generation of the software will have a keyword database attached for every subject possible to ensure that every student takes different keywords (chosen randomly from the stock).

      Then your grades are pretty much dependent on whether the random number generator chooses keywords that the grading software likes.

      I fail to see the difference to now, to be honest, it's just way less work on the student's side.

      As someone who graded hundreds of essays while serving as a teaching assistant for a senior-level engineering ethics course, I have to say that I find your lack of integrity rather appalling. Your moral obligation to write the essay yourself is independent of the method they use for grading it. Just because someone else is doing a lousy job does not mean that you suddenly have a license to short-change them for what you're obligated to do.

      I would guess that I graded around 300-400 essays during the three semesters I served as a TA, and that I probably averaged around 20 minutes per essay, since I was a strong believer in providing useful feedback over things the students could improve, even if they weren't necessarily incorrect. That said, other TAs spent as little as a minute or two per essay, and barely provided any feedback at all. Regardless of how much time the TAs did or didn't spend on the essays, however, the students had the same obligations, and rightfully so.

        The English department has some nice courses on compositional writing where I can get real feedback on my progress on those skills. As far as the machine-graded essays for any other Department -- either I understood the topic before writing the essay or I didn't and if I didn't then a no-feedback essay isn't going to fix the problem.

It was not my intent to use my former position in such a manner, though I can certainly see how it comes across that way. The fault lies with me on that one. I should have been more careful.

              If it's possible to write software that can capably analyze how skilled we are at communicating, I'd have trouble coming up with any objections to using it, given that it could successfully serve the same purpose as the human grader. That said,

    I don't see a problem with automated essay graders in principle. It's just that the current essay graders are no good. Once we are able to make computer software that can actually understand essays as well as a human it will be should be perfectly competent to grade an essay.

    I certainly see the motivation to have a computer grade essays. Who wants to read multitudes of mediocre essays. I might rather be put in solitary confinement. I am all for the automated essay graders, but only after they can be proven to be as competent as a human.

    I have no idea how to make a such a competent essay grader, but I do know how to grade an essay grader. You have a bunch of computer graders and human graders grading the same essays. If the computer graders show a more consistent performance than the humans (i.e. are the outlier less frequently), then the computer grader is better.

    If a paper is scored by 4 human judges and a computer, and the humans score the paper 1, 2, 3, 4, and the computer scores the paper as a 9, then it means that according to most of the human graders, the computer was way off. Essays are inherently subjective. Are the humans right or is the computer right? Who cares it doesn't matter.

    If a paper is scored by 4 human judges and a computer, and the humans score the paper 4, 5, 7, 9, and the computer scores the paper as a 6, then it means that according to every human grader, the computer did better than half the humans.

    If a computer can do better than the humans even by human standards, then I think it's fair to say that a computer is good enough.
