26、dly for the unexpected rather than search for answers.A I have always been a poor test-taker.So it may seem rather strange that I have returned to college to finish the degree I left undone some four decades ago.I am making my way through Columbia University,surrounded by students who quickly supply

28、terms and finals,and now I have a professor who issues take-home ones.I was excited when I learned this,figuring I had a full week to do the research,read the texts,and write it all up.In fact,I was still rewriting my midterm the morning it was due.To say I had lost the thread is putting it mildly.C

29、 As I was suffering through my week of anxiety,overthinking the material and guessing my grasp of it,I did some of my own polling among students and professors.David Eisenbach,who teaches a popular class on U.S.presidents at Columbia,prefers the in-class variety.He believes students ultimately learn

30、 more and encourages them to form study groups.“That way they socialize over history outside the class,which wouldnt happen without the pressure of an in-class exam,”he explained,“Furthermore,in-class exams force students to learn how to perform under pressure,and essential work skill.”欢迎您阅读并下载本文档，本

32、 have what they call an“honor code,”though if you are smart enough to get into these schools,you are either smart enough to get around any codes or hopefully,too ethical to consider doing so.As I sat blocked and clueless for two solid days,I momentarily wondered if I couldnt just call an expert on t

33、he subject matter which I was tackling,or someone who took the class previously,to get me going.E Following the Harvard scandal,Mary Miller,the former dean of students at Yale,made an impassioned appeal to her schools professors to refrain from take-hone exams.“Students risk health and well being,as

34、 well as performance in other end-of-term work,when faculty offers take-home exams without clear,time-limited boundaries,”she told me.“Research now shows that regular quizzes,short essays,and other assignments over the course of a term better enhance learning and retention.”欢迎您阅读并下载本文档，本文档来源于互联网，如有侵

35、权请联系删除！我们将竭诚为您提供优质的文档！整理为 word 格式 F Most college professors agree the kind of exam they choose largely depends on the subject.A quantitative-based one,for example,is unlikely to be sent home,where one could ask their older brothers and sisters to help.Vocational-type classes,such as computer science

36、 or journalism,on the other hand,are often more research-oriented and lend themselves to take-home testing.Chris Koch,who teaches“History of Broadcast Journalism”at Montgomery Community College in Rockville,Maryland,points out that reporting is about investigation rather than the memorization of min

38、m preferences vary,too,often depending on the subject and course difficulty.“I prefer take-home essays because it is then really about the writing,so you have time to edit and do more research,”says Elizabeth Dresser,a junior at Barnard.Then there is the stress factor.Francesca Haass,a senior at Mid

41、,they should be a breeze.”H How students ultimately handle stress may depend on their personal test-taking abilities.There are people who always wait until the last minute,and make it much harder than it needs to be.And then there those who,not knowing what questions are coming at them,and having no

42、 resources to refer to,can freeze.And then there are we rare folks who fit both those descriptions.I Yes,my advanced age must factor into the equation(等式),in part because of my inability to access the information as quickly.As another returning student at Columbia,Kate Marber,told欢迎您阅读并下载本文档，本文档来源于互

44、 to share,When I asked his opinion on this matter,he responded,“I like in-class exams because the time is already reserved,as opposed to using my free time at home to work on a test,”he responded.It seems to me that a compromise would be receiving the exam questions a day or two in advance,and then
