Computer graded essays full of flaws

Grade Essays 10x Faster (Episode 20)

I've said for decades that you can create a technical presentation that misses a key component preventing people from duplicating your results and nobody will notice. They often include phrases like "We implemented the Navier-Stokes equations This is the fancy-pants textbook version of "The solution is left as an exercise to the reader.

That's because the venue is the incorrect one for imparting sufficient detail to allow others to duplicate what you are doing.

Position Statements

A technical presentation is intended to report your findings or results, not every step necessary to duplicate them. Nobody will notice that they can't duplicate what you've just presented because they didn't come to the talk to find out how to duplicate what you've done. If you want to duplicate someone's results, you talk to him after the presentation and work it out. Even the paper they are presenting is missing key steps. I'm sure that's by design because they're hoping to get paid a lot of money to tell you the recipe for the secret sauce.

And as a Motherboard experiment demonstrated, some of the systems can be fooled by nonsense essays with sophisticated vocabulary. The people who write such essays most likely have promising futures in management consulting, and they definitely should be admitted so that they can work towards their MBAs.

Fooled by gibberish and highly susceptible to human bias, automated essay-scoring systems are being increasingly adopted , a Motherboard investigation has found. From a report: Every year, millions of students sit down for standardized tests that carry weighty consequences.

National tests like the Graduate Record Examinations GRE serve as gatekeepers to higher education, while state assessments can determine everything from whether a student will graduate to federal funding for schools and teacher pay. Traditional paper-and-pencil tests have given way to computerized versions.

And increasingly, the grading process -- even for written essays -- has also been turned over to algorithms. Natural language processing NLP artificial intelligence systems -- often called automated essay scoring engines -- are now either the primary or secondary grader on standardized tests in at least 21 states, according to a survey conducted by Motherboard. Three states didn't respond to the questions.

  • essay on the origin of languages summary;
  • Essay on the flaws of the PARCC tests.

Of those 21 states, three said every essay is also graded by a human. But in the remaining 18 states, only a small percentage of students' essays -- it varies between 5 to 20 percent -- will be randomly selected for a human grader to double check the machine's work.

But research from psychometricians -- professionals who study testing -- and AI experts, as well as documents obtained by Motherboard , show that these tools are susceptible to a flaw that has repeatedly sprung up in the AI world: bias against certain demographic groups. Essay-scoring engines don't actually analyze the quality of writing. They're trained on sets of hundreds of example essays to recognize patterns that correlate with higher or lower human-assigned grades.

They then predict what score a human would assign an essay, based on those patterns. This discussion has been archived. No new comments can be posted. More Login. Re: Score: 1.

But it's on a computer, and it's doing the same thing as at least some human graders. The computer is bettter than human graders Score: 3. That is not to say the computer is any good. But neither are the humans that mark these tests. When doing reviews by experts, the computers do a better job on average than humans. And at least the computer is consistent. AI is useful as an assistant. I'm not sure a lot's been done feeding neural nets into neural nets or using AI to try to work out proofs for humans to sample.

Re: Score: 3. There was already an article posted on this. Once you stop verifying the results the AI produces, once let loose you're operating on faith. Even when every effort is made to in good faith produce results comparable to a human effort things can go awry. Ironically human verification alone has many problems.

The obsession with AI and political correctness is already demonstrating the problem with trainers. Looks wrong? Fix it. Looks right? Ignore it. I've already seen a perfect example of this with PC. Re: Score: 2 , Insightful. There's nothing said about proper English. The AI likely grades based on grammatical structure and vocabulary, but how good is it with the quality of the content and the strength of an argument? A one-size-fits-all algorithm does penalize students who write differently, even if it is by choice.

Writing is about communication, and sometimes, art. Sometimes that means you should use very simple language, and short, terse sentences, and sometimes the contrary.

In a compound subject or object, the pronoun Me must be on the right. In the sentence starting with "should be no problem" This verbal group is missing a subject.

You only got one out of three of those right. It isn't about proper or improper english, it is about word choices. I could recall years ago working with a teacher who could tell what kinds of books people read by the 'feel' of their essays, and I've worked with linguists who can tell which part of the country you were from or which foreign country you learned english in. All correct, all proper, but they pick up a certain flavor depending on what media they consume. The bias tends to come in where people tend to react more positively to submissions.
