Grading Software Offers Professors a Break By John Markoff, New York Times
ESL Voices Lesson Plan for this post with Answer Key.
Robotic grading is not really new. There are already automated grading systems for multiple-choice and true-false tests used in schools everywhere in the U.S. Teachers spending hours correcting written essays is also nothing new. What is different is having essays corrected by an automated software program. The idea of using artificial intelligence in place of teachers to grade essays has not been accepted by everyone, especially those in the teaching profession. Will this type of program benefit teachers and students? The following article offers the pros and cons of robotic essay grading.
Excerpt:
“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.
EdX, 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. The new service will bring the educational consortium into a growing conflict over the role of automation in education.
Although automated grading systems for multiple-choice and true-false tests are now widespread, the use of artificial intelligence technology to grade essay answers has not yet received widespread endorsement by educators and has many critics.
Anant Agarwal, an electrical engineer who is president of EdX, 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…
But skeptics say the automated system is no match for live teachers. One longtime critic, Les Perelman…a retired director of writing and a current researcher at M.I.T. has drawn national attention several times for putting together nonsense essays that have fooled software grading programs into giving high marks. He has also been highly critical of studies that purport to show that the software compares well to human graders.
He is among a group of educators who last month began circulating a petition opposing automated assessment software. The group, which calls itself Professionals Against Machine Scoring of Student Essays in High-Stakes Assessment, has collected nearly 2,000 signatures, including some from luminaries like Noam Chomsky…
The group’s statement reads in part: “Computers cannot ‘read. Let’s face the realities of automatic essay scoring… They cannot measure the essentials of effective written communication: accuracy, reasoning, adequacy of evidence, good sense, ethical stance, convincing argument, meaningful organization, clarity, and veracity, among others.
But EdX expects its software to be adopted widely by schools and universities. EdX offers free online classes from Harvard, M.I.T. and the University of California, Berkeley; this fall, it will add classes from Wellesley, Georgetown and the University of Texas. In all, 12 universities participate in EdX, which offers certificates for course completion and has said that it plans to continue to expand next year, including adding international schools.
Mark D. Shermis, a professor at the University of Akron in Ohio, supervised the Hewlett Foundation’s contest on automated essay scoring and wrote a paper about the experiment. In his view, the technology — though imperfect — has a place in educational settings. With increasingly large classes, it is impossible for most teachers to give students meaningful feedback on writing assignments.” Read more…
