And then, instead of being done with the exam, imagine that the system would immediately let you rewrite the test to try to improve your grade.B E

35、dx,the nonprofit enterprise founded by Harvard and the Massachusetts Institute of Thnology(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 institutioons that wants to use it. The software uses artifici

36、al 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 the automation education. Altough automated grading systems for multiple-choice and true-false tes

37、ts are now widespread, the use of artificial intelligence technology to grade essay answers has not yet provided widespread acceptance by educations and has many critics.D Anant Agarwal, an electrical engineer who is president of Edx, predicted that the instant grading software would be a useful tea

38、ching 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.“Thers is a huge value in learning wit

40、hat have fooled software grading programs into giving high marks. He has also been highly critical of studies claiming that the software compares well to human grades.F He is among a group of educators who last month began circulating a petition(呼吁) opposing automated assessment software. The group,

41、 which calls itself Professionals Against Machine Scoring of Student Essays in High-Stakes Assessment, has collected nearly 2,000 signatures, including some from famous people like Noam Chomsky.G “Lets face the realities of automatic essay scoring,” the groups statement reads in part. “Computers can

42、not read. They cannot measure the essentials of effective written communication: accuracy, reasoning, adequacy of evidence, good sense, ethical (伦理)position, convincing argument, meaningful organization, and clarity, among others.”H But EdX experts its software to be widely by schools and universiti

In all, 12 universities participate in EdX, which offers certificates for course completion and has said that it plans

44、to continue to expand next year, including adding international schools.I The EdX assessment tool requires human teachers, or graders 100 essay or essay questions. The system then uses a variety of machine-learning techniques to train itself to be able to grade any number of essays or answers automa

46、ange of companies offering commercial programs to grade written test answers, and four states Louisiana, North Dakota, Utah and West Virginia are using some form of the technology in second schools. A fifth, Indiana, has experimented with it. In some cases the software is used as a “second reader”,

47、to check the reliability of the human graders.K But the growing influence of the Edx consortium to set standards is likely to give the technology a boost. On Tuesday, Stanford announced that it would work with EdX to develop a joint educational system that will make use of the automated assessment technology.L Two start-ups, Coursera and Udacity, recently founded by Stanford faculty members to create “massive open online courses,” or MOOCs, are also committed to automated assessment systems because of the value of instant feedback. “it
