17、9) and disabled; refrain from using (30) or threatening language; and be courteous and polite to fellow passengers and staff.Those who refuse, or are caught behaving in a rude manner, will have their free travel passes (31) The plan-a key part of Mr. Johnsons re-election bid-will initially affect th

22、fe of a given group of human beings. In this (36) , every group has a culture, however savage, undeveloped, or uncivilized it may seem to us.To the professional anthropologist (人类学家), there is no intrinsic (37) of one culture over another, just as to the professional linguist there is no intrinsic h

23、ierarchy (等级制度) among languages.People once thought of the languages of backward groups as (38) and undeveloped forms of speech, consisting largely of grunts and groans. While it is possible that language in general began as a series of grunts and groans, it is a fact established by the study of “ba

24、ckward“ languages that no spoken tongue answers that description today. Most languages of uncivilized groups are, by our most severe standards, extremely complex, delicate, and ingenious pieces of machinery for the (39) of ideas. They fall behind our Western languages not in their sound patterns or

Even in this department, however, two things are to be noted: 1. All languages seem to (42) the machinery for vocabulary expansion,

26、 either by putting together words already in existence or by borrowing them from other languages and adapting them to their own system. 2. The objects and activities requiring names and distinctions in “backward“ languages, while different from ours, are often surprisingly (43) and complicated.This

29、the student, and helps her learn what she needs to know. “You guys sound like youre from the future,“ Jose Ferreira, the CEO of the education technology startup Knewton, says. “Thats the most common reaction we get from others in the industry.“BSeveral million data points generated daily by each of

30、1 million students from elementary school through college, using Knewtons “adaptive learning“ technology to study math, reading, and other fundamentals. Adaptive learning is an increasingly popular catchphrase denoting educational software that customizes its presentation of material from moment to

31、moment based on the users input. Its being hailed as a “revolution“ by both venture capitalists and big, established education companies.“CFerreira started Knewton in 2008 with more or less the same vision he believes in today: to enable digital technology to transform learning for everyone and to b

32、uild the company that dominates that transformation. “Look at what other industries the Internet has transformed,“ he once said. “It laid waste to media and is rebuilding it. But for whatever reason, people dont see it with education. It is blindingly obvious to me that it will happen with education

33、. All the content behind education is going to move online in the next 10 years. Its a great shift. And that is what Knewton is going to power.“DThe recommendation engine is a core technology of the Internet, and probably one you encounter every day. Google uses recommendations: other people who ent

34、ered these search terms clicked on this page, so well show it to you first. Amazon uses them: other people who bought this book also bought that book. The more you use one of these websites, the more it knows about you-not just about your current behavior, but about all the other searches and clicks

35、 youve done. In theory, as you spend more time with a site its recommendations will become more personalized even as they also draw on everyone elses interactions within the platform.EKnewton, at base, is a recommendation engine but for learning. Rather than the set of all Web pages or all movies, t

36、he learning data set is, more or less, the universe of all facts. For example, a single piece of data in the engine might be the math fact that a Pythagorean triangle has sides in the ratio 3-4-5, and you can multiply those numbers by any whole number to get a new set of side lengths for this type o

37、f triangle. Another might be the function of “adversatives“ such as “but,“ “however,“ or “on the other hand“ in changing the meaning of an English sentence.FFerreira calls these facts “atomic concepts,“ meaning that theyre indivisible into smaller concepts-he clearly likes the physics reference.When

38、 a textbook publisher like Pearson loads its curriculum into Knewtons platform, each piece of content-it could be a video, a test question, or a paragraph of text-is tagged with the appropriate concept or concepts.GLets say your school bought the Knewton-powered MyMathLab online system, using the sp

39、ecific curriculum, say, Lials Basic College Mathematics 8e. When a student logs on to the system, she first takes a simple placement test or pretest from the book, which has been tagged with the relevant “atomic concepts.“ As a student reads the text or watches the video and answers the questions, K

40、newtons system is “reading“ the student as well-timing every second on task, tabulating (把列成表格) every keystroke, and constructing a profile of learning style: hesitant or confident? Guessing blindly or taking her time?HBased on the students answers, and what she did before getting the answer, “we ca

41、n tell you to the percentile, for each concept: how fast they learned it, how well they know it, how long theyll retain it, and how likely they are to learn other similar concepts that well,“ says Ferreira. By watching as a student interacts with it, the platform deduces.IThe platform forms a person

42、alized study plan based on that information and decides what the student should work on next, feeding the student the appropriate new pieces of content and continuously checking the progress. A dashboard shows the student how many “mastery points“ have been achieved and what to do next. Teachers, li

43、kewise, can see exactly which concepts the student is struggling with, and not only whether the homework problems have been done but also how many times each problem was attempted, how many hints were needed, and whether the student looked at the page or opened up the video with the relevant explana

44、tion. The more people use the system, the better it gets; and the more you use it, the better it gets for you.JIn a traditional class, a teacher moves a group of students through a predetermined sequence of material at a single pace. Reactions are delayed-you dont get homework or pop quizzes back fo

45、r a day or two. Some students are bored; some are confused. You can miss a key idea, fall behind, and never catch up. Software-enabled adaptive learning flips all of this on its head. Students can move at their own speed. They can get hints and instant feedback. Teachers, meanwhile, can spend class

46、time targeting their help to individuals or small groups based on need.KFerreira is able to work with competitors like Pearson and Wiley because his software can power anybodys educational content, the same way Amazon Web Services provides the servers for any website to be hosted in the cloud. But b

47、efore it had any content partners, as a proof of concept, Knewton built its own remedial college math course using its software platform. Math Readiness was adopted starting in the summer of 2011 at Arizona State University; the University of Nevada, Las Vegas; and the University of Alabama.LAt ASU, students worked through the computer material in Knewtons Math Readiness program on their own or in small groups, with instructors spending face-to-face time working on problem solving, critical thinking, and troubleshooting specific concepts. After two semesters of use, course withdra
