Indiana First With Computerized Grading 524

Mz6 writes "Computerized grading has been talked about previously, however, the New York Times reports that Indiana has become the first state to grade high school English essays by computer. The computerized grading process, called 'e-rater', uses a 6-point rating scale and uses artificial intelligence to 'mimic the grading process of human readers'. The system was tested over a 2-year pilot program and produced results virtually identical to those of trained readers. The big question is, will other states begin to emulate Indiana by tossing human grading?"

    ... and produced results virtually identical to those of trained readers.

    Funny, because the way I read that is, "Produced lawsuits where the cost is virtually identical to about 20 times the short-term savings."

    I see this coming from both sides. The obvious, the grading was wrong, and I lost a scholarship. To other people suing after dropping out of collage level english classes (the test said I was better than I was).

            Why is that? If you had two students, one that you knew was brilliant and one that you knew wasn't the sharpest knife in the drawer, would you give them the same grade for the same paper? If the smarter person put 20 minutes of effort into the paper while the dumber person worked their ass off for a week on it, why shouldn't the grades be different?

            Why punish those with ability, why reward those who are not talented. Surely they won't be punished or rewarded in the same manner in real life. If the talented one was cruising and not expending any effort, thats his perogative. If he can be a productive member of society without effort thats fine, even if he has the potential to eb the next great mind, it's still his choice. The rewarding of those who work hard is important but if they work hard to only measure up to the minimium standard then they belong to that minimium standard regaurdless of how much effort they put in.
            • Darn straight. I'm all for making dumb people feel not so bad about things they can't control - like being dumb - but not at the expense of making the non-dumb feel dumb. There's a lot to be said for working smarter, not harder, and a lot to be said for those who have figured that out on their own. English provides several correct ways to do something and some incorrect ways of communicating. An "A" paper is an "A paper, regardless of the source and effort put in by said source.

              If grading is intended as a motivator to encourage each student to perform his/her best, then more effort should yield a higher grade. Likewise, if grading is intended to reflect the student's ability to perform in a real-world situation, effort should probably yield a higher grade: folks who work hard tend to do better than folks who are marginally smarter but don't work hard, in real-life situations. But if grading is intended to reflect only the quality of the work that was submitted, then sure -- effort shouldn't count at all.


              This issue cuts deep into the heart of what grading is for -- it's possible for smart people to reasonably disagree, depending on what they think the intent of the grade is. Since grades are put to many uses, there are many answers to the question.


              As a college instructor, I tend to use a strict grading protocol -- and then "bump up" a few of the students. If someone comes in to my office every week and really struggles to understand the concepts, but the computer tells me that they earned a "C+" -- they're likely to find a "B-" on their transcript. But if someone who's smart enough to get an "A" blows an exam from being hung over, that person gets little or no sympathy.

                > If grading is intended as a motivator

                A grade is used to show how well you know a subject. If I knew a subject completely before starting the class & wrote the same level of paper as someone who studied his ass off, we deserve the same grade. He should not be given a better grade than me just because he waited for this particular class to learn a subject. Why am I judged differently because I took the initiative to learn the information earlier than I absolutely had to?

                No, schools are not there to make you feel good about yourself (that's obvious), they are there to make sure you know the minimum information to pass a class. That'a a D. Then, if you know more, you get a better grade. The amount of work you put into it is irrelevant. In fact, if you put more work into it than you should have, it means you are not doing well, and once you get into the "real world," where you have strict deadlines, you don't have the option of getting paid more just because you worked harder for the same result. The exact OPPOSITE is true, in fact.

                School should help people prepare for life. If someone is given a grade they did not deserve, they are being improperly trained how to work.

                A problem, however, is with the PARENTS. Many students are C students, that's all there is to it. But they get all high & mighty towards the school if they see their child work very hard for a low grade. They figure their child isn't good enough if they don't have all As, but that they deserve them just for hard work.

                If life had a payrate based on how hard you worked, vs. your productivity, I would start working as an astrophysicist. I wouldn't get anything done, since I know nothing about the work, but I would sure as hell work my ass off. Do you think anyone wants an employee like that?

            The real answer is to adjust your teaching methods per student based on subjective analysis. A low objective mark on a paper or test would indicate that, ideally, the teacher needs to pay closer attention to the needs of that student, and teach him in a way he can learn. (VERY few teachers have the time and skill required for this, unfortunately).

            You can't grade subjectively because those grades will be compared objectively down the line. You can't say "this is pretty good for kevin, I'll give him an A", but then say "josh's paper is way better than kevin's paper, but josh is a bright kid, so I'm giving him a C". Kevin will think he's mastered the english language while Josh will go insane trying to achieve perfection.

            Grading, when used for anything other than helping the teacher learn about each students, just plains sucks, and is only used for competition.

      I disagree. I see lawsuits as no more likely. Furthermore, any process where you're subjectively evaluting something there has to be quality controls and an appeals process. My wife once held a part time job grading essay questions on a high school exit exam. Every few hours of grading exams, she would have to take and pass a "calibration battery" of 10 exams. Quality control is fundamental to the process.

      What I see as being problematic is kids learning to beat the system. Typically these systems are predicated on gramatical analysis (use of punctuation and sentence compeleteness) and evidence of citing the text the question is based off. I'd bet its a real easy system to beat.
    • I don't think that bad grading is what's hurting your ability to get a writing-based scholarship, bud. Your comment is barely comprehensible, has almost no examples of correct English grammar, and has some spelling issues and capitalization deficiencies, as well.
    • If it doesn't already, I would expect a service like this will eventually include plagiarism detection, due to marketing pressure if nothing else. This is something that human graders do, at least over the space of papers they grade and works they remember.

      But if plagiarism detection is added, then the grading service would have to make and retain some encoding of each graded paper, a derivative work, in its database.

      Once that happens, the grading service also becomes subject to all of the issues already

        Actually, anything that would encourage students to re-write their papers and improve their writing would be pretty amazing.

This is basically exactly what we had to do. Write the most horrible peice of trash you could think of, but make it adhere to a few preset guidelines and BAM instant grade. My first time taking it I wrote a rather good peice of work if I do say so myself. Problem was, it didn't ahhere to their simply 5 paragraph, introduction, 3 body, and conclusion. I did horrible.

      The whole idea of an automated grading system for essays is insane to begin with. The single most important aspect of an essay is its content, not its form. Form and grammar are important in conveying a message, but the message is what is actually important. The things an automated grading system can grade should not make up much of an essay's total grade.

      Besides, anyone who has read much literature knows that many great authors play with grammar, spelling, and form in non-standard ways in order convey a message. An automated system would grade them poorly, because only those who conform exactally to the rules get a good grade. Is our goal to turn all of our students into mindless automatons whose only goal is to churn out exactally the same drivell as the next guy?

      They are not graded fairly, and they determine 10% of the final grade.

      10% of the grade on the essay? Or in a particular class? 10% on the essay may actually be tolerable, because that means that at least a human actually read it to give the other 90% of the grade.

      Right. The software can grade things like spelling, vocabulary, grammar, and syntax, but it won't grade the quality of the ideas expressed or the depth of understanding displayed.

    than it does about the software, methinks. I imagine it gives helpful hints like the ones I always turn off in Microsoft Turd. Any construction that deviates from the norm in a boring business document apparently triggers the "grammotron" or whatever they call it. A human reader has some appreciation for style and may actually accept something a little different for the sake of variety and sparkle.

    Not that there's anything in this post that serves as an example. I guess that's because I was graded by humans. Seriously, I don't recall getting any encouragement in writing back in the '70s in high school, and not much in college. I guess it wouldn't have been any worse if the Grade-O-Vac was inspecting my papers instead of my mostly-marginally-literate teachers. There were several exceptions, but they focused much more on reading than on writing. I suspect they had a lot greater effect that way--I know they had a great effect on me.

  • I cannot believe they are doing this. It is undoubtedly a deep AI problem to properly grade an essay. You have to be able to understand if statements connect logically to form an argument, you have to understand analogy, you have to understand sarcasm, etc... this is so far beyond our current capability.

    As implemented, I'm sure there are easy ways to scam this system by writing gibberish. Who sold them this idea? I want to know the person responsible for this abuse of computing.

    The system was tested over a 2-year pilot program and produced results virtually identical to those of trained readers.

    So it gives its favorite students 'A's without reading, least favorite students 'F's, and the rest arbitrary grades somewhere in between to mimic a bell curve?

    How do they judge the content? What if you submit an excellent paper on middle ages history but the assignment was on socialism?

    Human feedback is required in order to learn how to write well, you can't just expect a machine to tell you how to improve your writing. Grammar perhaps, but not ideas and how to let them flow coherently.

    In order for these students to get that feedback someone has to read it, and since they're reading it anyway, why not just grade it then?

    By creating a vernacular consisting of elongated words and sophisticated verbiage, obviously indifferent to definition but simultaneously observing grammar regulations while eschewing colloquialisms, perhaps students may increase individual chances of achieving substantial academic acclaim.

    My writing style is somewhat peculiar, though I can't exactly say how (or even approximately how). Partially as a result of this, my marks in English class over the years of high school ranged from C to A, depending not on me, but on who the teacher was. If the teacher happened to like my style, I got a good mark.

    This is annoying, but at least each year there was a different teacher, who may like my style. If the marking is computerised, it will not change; if your writing doesn't fit what the computer likes, you're screwed; likewise, if it does like it, you might never learn to express yourself more creatively (ie you'll be punished for trying to write in a manner different from what you usually do).

    There are possibilities in this technology, but I suspect that it will be a long while before the eccentric aren't labeled as poor writers.

    A computer can check spelling and even grammar to a certain extent. However, it cannot evaluate factual accuracy, strength of argument. Even with spelling, the computer is not likely to catch improper use of homonyms. I can guarantee you that it will be possible to create a piece of writing that is utter crap that would get an A+ using this or any other possible computerized grading system. Unfortunately, there are probably many teachers out there who make poorer graders than this system does. The answer to the problem of poor-quality teaching is not replacing teachers with computers; the answer is a combination of better teacher pay and putting higher standards in place for our teachers via competency testing.

    I believe that (English) essay grading is harder than grading science exams based on problem solving (no bubbles please), at least if essays are about content and not just grammatical correct sentences.

    I say this because there is an objective criteria for grading the solution to a physics or math problem: correctness. For essays I do not beleive that we (and the current state of AI) can come up with an exact criteria like that. You might determine whether an essay is too different from essays which were written by experts, but cannot a very different essay to be just as good?

    To my knowledge the AI programs can solve physics problems which are limited to some well defined domain (for example: http://www.cs.utexas.edu/users/novak/cgi/isaacdemo .cgi though that is from 1977...) I am not aware of programs grading physics problem solutions.

    I will accept an essay grading program after they grade solutions to math and physics problems.

    I conjecture that some writers would feel offended if their essay did well according to the program: they might think it means they are too conformist and conservative and not novel in their approach...

    Writing is not mathematics. Good writing should not go along some artificial standard. Just because my paper is grammatically correct, has a topic sentence, 3 supporting paragraphs, and a conclusion doesn't mean it is good. Good writing needs a flow of ideas from one paragraph to another. It needs finesse, style, grace. This is like an IQ test for english writing. It would do very well in identifying poor writers - but could never identify a great one. I'm sorry ee cummings, your use of punctuation is poor 1/6. There are examples like this in books on taking the various standardized tests - any truly excellent writer is likely going to do badly. Why? The rules of the english language are guidlines, which may be broken when appropriate. This is just the mechanization of another facet of society, and should be tossed out with the rest of the garbage.

    I don't think that automatized, high-school-level grading is an all-bad thing. We can call it unfair if we like, but as someone who grades a lot of stuff I can tell you that I'm nothing like fair. I don't always even know how to distinguish a B- from a C+, and I just go with my gut, which, as far as I can tell, is much like flipping an internal coin. If we looked at human grade assigners as an algorithm, we would find a whole lot of stuff wrong, even among those of us who try hard to be fair (cover author names, compare close grades for consistency, keep a constant mood, that sort of stuff).

    But I think that if a computer grading program which is no worse than humans could be devised, it would be a great learning tool. A lot of people make it to college as borderline illiterates. I'm not kidding. I read a lot of their crap. That's because their HS teachers were too overworked to grade their writing, so they didn't assign much. If a computer program could auto-grade and give detailed comments on how to improve the writing, high school students could be assigned an essay per week, and really get the hang of writing well. Teachers could focus on teaching instead of tedium.

    Sure, the first grading applications are going to make a few serious errors. This is the first stage of every application when a computer is asked to interpret rich data. Early voice recognition sucked. Now it sucks much less, and it will just keep getting better. Same with OCR, chess software, machine translation, etc. So the right debate to have is about when this will be good enough for school use, and not whether. I'm prepared to admit that the answer to the right question is "not yet" (I'm sure how deep the current problems go), but I fully support working on this system until it works right.

      Unfortunately, the system described here doesn't return any such useful feedback. The Indiana system returns a grade from a six point scale. No comments, no criticism, no hint that the evaluation is meaningful.

      Incidentally, what's this about "teaching instead of tedium"? Grading essays by evaluating construction, insight, and creativity should be part of the teaching process. Perhaps this is something that should be addressed earlier in the education of these students - if they're reaching college as "borderline illiterates" there is a problem - but grading in general is a part of teaching. If I were a student, I'd want to know that a human being - at some point - had bothered to look at the work that I did.

    I live in Indiana (no, NOT India) and took this test. Being a techie, I figured I'd try to fake out the system. This test works out to be 10% of the final grade and since I had a 98 going into the test, I figured I could afford to gamble a little, figuring if it back-fired I could blame it on a computer error since every one would figure the kid with a 98 MUST be telling the truth.

    I almost wimped out. I wrote about 80 percent of the essay (about influence of pop-culture on society - and silly me I always thought society influences pop-culture but anyway). I had 5 paragraphs - 1 intro, 3 body - 1 half-assed conclusion. I reoreded the paragraphs, copied the one I felt was the best written and pasted it into the body 3 times.

    Guess what I got.....6/6 (six point grading scale which is pretty messed up because a 5/6 is an 83%). Hopefully they won't audit mine....

    A computer can not replicate certain aspects of the grading process. Sure they can grade spelling and grammar and probably certain aspects of your writing style but there is plenty of important aspects of writing that they can not grade you on.

    For instance, does your essay really grab the reader? Anyone here who reads technical documents knows what I'm talking about. There are some writers that, no matter how dull the subject, can make their work interesting and fun to read. A computer can not possibly grade one on that. I have a good friend who's a high school English teacher and occasionally I'll read some of the things written by his students. I've come across plenty of papers that are grammatically correct, have perfect spelling and are fairly well written from a syntactic and stylistic point of view, but are just plain boring to read. Then I'll move on to another paper, about the same subject, which is interesting and actually fun to read.

    That's just one example of something a computer can not possible take into account when grading an essay. The bottom line is that a computer will never be able to grade you on certain subjective things, which although they are subjective and therefore open to a certain amount of interpretation depending on the person doing the grading, are nevertheless still very important aspects of good writing.

    With spelling and grammar check, almost any average student can churn out a paper that is going to be mostly correct; however it still takes a good writer to produce something interesting. In my opinion, an interesting paper with a few minor spelling, grammar or syntactic errors is just as good as a boring paper with no spelling, grammar or syntactic errors.

    A good essay always consists of an introductory paragraph, three body paragraphs, and a closing paragraph.

    It is essential that every paragraph begin with a topic sentence. The first paragraph should state the thesis, or point of the essay. Since computers cannot actually understand the entire essay, you can assume that it will only be judging the local coherence of writing which is free to run like a river, past Eve and Adam's, from swerve of shore to bend of bay, taking us by a commodius vicus of recirculation back to Howth Castle and environs.

    The second paragraph should make a point that present a countervailing view, the antithesis. Once again, spelling should be correct, the essay should be capable of passing a Microsoft Word grammar check, but after that we pass through grass behind the bush where a gull calls, coming far, ending here. Finn again? Take, but softly memory till thousands are given the keys to a way a lone a last a loved a long the river runs.

    The third paragraph should synthesize the material covered in the first two paragraphs. It is, however, important that any material obtained from external sources be modified so that it cannot be detected as an exact match for anything on the Web. So, she went into the garden to cut a lettuce leaf to make an mince pie; and at the same time a great wolverine, coming up the street, goes into the store. "What! No laundry detergent?" So he died, and she very imprudently married the barber, and they all fell to playing the game of catch as catch can till the gunpowder ran out at the heels of their boots.

    In conclusion, the final paragraph should recapitulate and summarize what has gone before: since you can be sure that a computer is capable of counting paragraphs, a good essay always consists of five paragraphs. If it has the right number of paragraphs and every word is spelled correctly, you are almost certain to get at least a passing grade.
