Essay-Grading Software Offers Professors a BreakA) Imagine taking a college exam, and, instead of handing in a blue

34、 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.

35、to try to improve your grade.B) EdX, the nonprofit enterprise founded by Harvard and the Massachusetts Institute of Technology (MIT) to offer courses on the Internet, has just introduced such a system and will make its automated (自动的) software available free on the Web to any institution that wants

36、to use it. The software uses artificial intelligence to grade student essays and short written answers, freeing professors for other tasks.C) The new service will bring the educational consortium (联盟) into a growing conflict over the role of automation in education. Although automated grading system

37、s 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 acceptance by educators and has many critics.D) Anant Agarwal, an electrical engineer who is president of EdX, predicted that the instan

38、t-grading software would be a useful teaching 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 overthe traditional classroom system, where students often wait days or weeks for grades

39、. There is a huge value in learning with instant feedback, Dr. Agarwal said. Students are telling us they learn much better with instant feedback.E) But skeptics (怀疑者) say the automated system is no match for live teachers.

42、ups statement reads in part. “Computers cannot read.? They cannot measure the essentials of effective written communication: accuracy, reasoning, adequacy of evidence, good sense, ethical (伦理的) position, convincing argument, meaningful organization, and clarity, among others.”H) But EdX expects its

43、software to be adopted widely by schools and universities. It offers free online classes from Harvard, MIT 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 certif

44、icates for course completion and has said that it plans to continue to expand next year, including adding international schools.I) The EdX assessment tool requires human teachers, or graders, to first grade 100 essays or essay questions. The system then uses a variety of machine-learning techniques

45、to train itself to be able to grade any number of essays or answers automatically and almost instantly. The software will assign a grade depending on the scoring system created by the teacher, whether it is a letter grade or numerical (数字的) rank.J) EdX is not the first to use the automated assessmen

46、t technology, which dates to early computers in the 1960s.
