It must also be capable of understanding both the grammatical structure, intent, and tone of a written response.Over the last few years, quite a bit of progress toward that requirement has occurred in the world of AI.That doesn't leave much room for the varied stylistic and creative writing styles students may use and ignores any objective judgment of their merit.
That's because they're still utilizing a system that isn't capable of comprehending written answers but instead seeks to compare it to known samples.
The problem with that approach is that it presupposes that the examples the AI has to use as guidelines are the only correct or incorrect responses.
Ed X, the nonprofit enterprise founded by Harvard and the Massachusetts Institute of Technology to offer courses on the Internet, has just introduced such a system and will make its automated software available free on the Web to any institution that wants to use it.
The software uses artificial intelligence to grade student essays and short written answers, freeing professors for other tasks.
Anant Agarwal, an electrical engineer who is president of Ed X, predicted that the instant-grading software would be a useful pedagogical tool, enabling students to take tests and write essays over and over and improve the quality of their answers.
He said the technology would offer distinct advantages over the traditional classroom system, where students often wait days or weeks for grades.“There is a huge value in learning with instant feedback,” Dr. “Students are telling us they learn much better with instant feedback.”But skeptics say the automated system is no match for live teachers.
Imagine taking a college exam, and, instead of handing in a blue book and getting a grade from a professor a few weeks later, clicking the “send” button when you are done and receiving a grade back instantly, your essay scored by a software program.
And then, instead of being done with that exam, imagine that the system would immediately let you rewrite the test to try to improve your grade.
In all corners of the education world, there's an ever-growing need to streamline and optimize all of the work that goes into teaching students what they need to know.
For decades, technology of all types has played a major role in those efforts.
