33、heet 2 Essay-granding Software Officers Professors a Break A Imagine taking a college exam,and instead of handing in a blue book and getting a grade from a professoer a few weeks later,clicking the“send”button when you are done and receiving a grade back instantly,your essay scored by a software pro

34、gram.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 Edx,the nonprofit enterprise founded by Harvard and the Massachusetts Institute of Thnology(MIT)to offer courses on the Internet,has just introduced suc

35、h 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 artificial intelligence to grade student essays and short written answers,freeing professors for other tasks.C The new service will bring the educational consorti

36、um(联盟)into a growing conflict over the role of the automation education.Altough 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 provided widespread acceptance by educations and has

37、many critics.D Anant Agarwal,an electrical engineer who is president of Edx,predicted that the instant 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

38、advantages over the traditional classroom system,where students often wait days or weeks for grades.“Thers 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 matte

39、r for live teachers.One longtime critic,Les Perelman，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 claiming that the software compares well to human grades.

40、F He is among a group of educators who last month began circulating a petition(呼吁)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 famous peo

41、ple like Noam Chomsky.G“Lets face the realities of automatic essay scoring,”the groups 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)position,convincing argument,meani

42、ngful organization,and clarity,among others.”H But EdX experts its software to be 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,Geogetown and the University of Texas.In all,12 u

43、niversities 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.I The EdX assessment tool requires human teachers,or graders 100 essay or essay questions.The system then uses a variety of

44、 machine-learning techniques to train itself to be able to grade 8 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 u

45、se the automated assessment technology,which dates to early computers in the 1960s.there is now a range 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 fift

46、h,Indiana,has experimented with it.In some cases the software is used as a“second reader”,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 Ed

47、X 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

48、of instant feedback.“it allows students to get immediate feedback on their work,so that learning turns into a game,with students naturally gravitating(吸引)to ward resubmitting the work until they get it right,”said Daphne Koller,a computer scientist and a founder of Coursera.M Last year the Hewlett F

49、oundation,a grant-making organization set up by one of the Hewlett-Packard founders and his wife,sponsored two$100,000 Prizes aimed at improving software that grades essay and short answers.More than 150 teams entered each category.A winner of one of the Hewlett contents,Vik Paruchurt was hired by E

50、dX to help design its assessment software.N“One of our focus is to help kids learn how to think critically,”said Vuchic,a program officer at the Hewlett Foundation.“It s probably impossible to do that with multiple-choice tests”.The challenge is that this requires human graders,and so they cost a lo
