CanDigital Textbook Truly Replace the Print Kind?

The shortcomings oftraditional print edition textbooks are obvious: For starters they’re heavy,with the average physics textbook weighing 3.6 pounds. They’re also expensive,especially when you factor in the average college student’s limited budget,typically costing hundreds of dollars every semester.

But the worst part isthat print version of textbooks are constantly undergoing revisions. Manyprofessors require that their students use only the latest versions in theclassroom, essentially rendering older texts unusable. For students, it meansthey’re basically stuck with a four pound paper-weight that they can’t sellback.

Which is why digitaltextbooks, if they live up to their promise, could help ease many of theseshortcomings. But till now, they’ve been something like a mirage(幻影)in the distance, more like a hazy(模糊的)dream than an actualreality. Imagine the promise: Carrying all your textbooks in a 1.3 pound iPad?It sounds almost too good to be true.

But there are a fewpilot schools already making the transition(过渡)overto digital books. Universities like Cornell and Brown have jumped onboard. Andone medical program at the University of California, Irvine, gave their entireclass iPads with which to download textbooks just last year.

But not all were eagerto jump aboard.

“People were tired ofusing the iPad textbook besides using it for reading,” says Kalpit Shah, whowill be going into his second year at Irvine’s medical program this fall. “Theyweren’t using it as a source of communication because they couldn’t read orwrite in it. So a third of the people in my program were using the iPad inclass to take notes, the other third were using laptops and the last third wereusing paper and pencil.”

The reason it hasn’tcaught on yet, he tells me, is that the functionality of e-edition textbooks isincredibly limited, and some students just aren’t motivated to learn new studybehavior.

But a new applicationcalled Inkling might change all that. The company just released an updatedversion last week, and it’ll be utilized in over 50 undergraduate and graduateclassrooms this coming school year.

“Digital textbooks arenot going to catch on,” says Inkling CEO Matt Maclnnis as he’s giving me a demo(演示)over coffee. “What Imean by that is the current perspective of the digital textbook is it’s anexact copy of the print book. There’s Course Smart, etc., these guys who takeany image of the page and put it on a screen. If that’s how we’re definingdigital textbooks, there’s no hope of that becoming a mainstream product.”

He calls Inkling aplatform for publishers to build rich multimedia content from the ground up,with a heavy emphasis on real-world functionality. The traditional textbookmerely serves as a skeleton.

At first glance Inklingis an impressive experience. After swiping(敲击)intothe iPad app (应用软件), which you can get for free here, he opens up a few different types oftextbooks.

Up first is a chemistrybook. The boot time is pretty fast, and he navigatesthrough (浏览 ) a few chapters before swiping into a fully rendered3D molecule that can be spun around to view its various building blocks.“Publishers give us all of the source media, artwork, videos,” he says, “Wehelp them think through how to actually build something for this platform.”

Next he pulls up a musiccomposition textbook, complete with playable demos. It’s a learning experiencethat attacks you from multiple sensory directions. It’s clear why this would besomething a music major would love.

But the most excitingpart about Inkling, to me, is itsnotation(批注)system. Here’s how it works!

When you purchase a usedprint book, it comes with its previous owner’s highlights and notes in themargins. It uses the experience of someone who already went through the classto help improve your reading (how much you trust each notation is obviously upto you).

But with lnkling, youcan highlight a piece of content and make notes. Here’s where things getinteresting, though: If a particularly important passage is highlighted bymultiple lnkling users, that information is stored on the cloud and isavailable for anyone reading the same textbook to come across. That means usershave access to notes from not only their classmates and Facebook friends, butanyone who purchased the book across the country. The best comments are thensorted democratically by a voting system, meaning that your social learningexperience is shared with the best and brightest thinkers.

As a bonus, professorscan even chime in (插话) on discussions. They’ll be able to answer the questions of students who arein their class directly via the interactive book.

Of course, Inklingaddresses several of the other shortcomings in traditional print as well.Textbook versions are constanly updated, motivating publishers by minimizingproduction costs (the big ones like McGraw-Hill are already onboard).Furthermore, students will be able to purchase sections of the text instead ofbuying the whole thing, with individual chapters costing as little as $2.99.

There are, however,challenges.

“It takes efforts tobuild each book,” Maclnnis tells me. And it’s clear why.

Each interactivetextbook is a media-heavy experience built from the ground up, and you can tellthat it takes a respectable amount of manpower to put together each one.

For now the app is alsoiPad-exclusive, and though a few of these educational institutions are givingthe hardware away for free, for other students who don’t have such a luxuryit’s an added layer of cost — and an expensive one at that.

But this much is clear.The traditional textbook model is and has been broken for quite some time.Whether digitally interactive ones like Inkling actually take off or notremains to be seen, and we probably won’t have a definite answer for the nextfew years.

However the solution toany problem begins with a step in a direction. And at least for now, that hazymirage in the distance? A little moretangible (可触摸的 ), a little less of a dream.

Passage One

Questions 57 to 61 are based on thefollowing passage.

Junk food is everywhere.We’re eating way too much of it. Most of us know what we’re doing and yet we doit anyway.

So here’s a suggestion offeredby two researchers at the Rand Corporation: Why not take a lesson from alcoholcontrol policies and apply them to where food is sold and how it’s displayed?

“Many policy measures tocontrol obesity(肥胖症)assumethat people consciously and rationally choose what and how much they eat andtherefore focus on providing information and more access to healthier foods,”note the two researchers.

“In contrast,” theresearchers continue, “many regulations that don’t assume people make rationalchoices have been successfully applied to control alcohol, a substance — likefood — of which immoderate consumption leads to serious health problems.”

The research referencesstudies of people’s behavior with food and alcohol and results of alcoholrestrictions, and then lists five regulations that the researchers think mightbe promising if applied to junk foods. Among them:

Density restrictions:licenses to sell alcohol aren’t handed out unplanned to all comers but are allotted(分配)based on the number ofplaces in an area that already sell alcohol. These make alcohol less easy toget and reduce the number of psychological cues to drink.

Similarly, theresearchers say, being presented with junk food stimulates our desire to eatit. So why not limit the density of food outlets, particularly ones that sellfood rich in empty calories? And why not limit sale of food in places thataren’t primarily food stores?

Display and salesrestrictions: California has a rule prohibiting alcohol displays near the cashregisters in gas stations, and in most places you can’t buy alcohol atdrive-through facilities. At supermarkets, food companies pay to have theirwares in places where they’re easily seen. One could remove junk food to theback of the store and ban them from the shelves at checkout lines. The othermeasures include restricting portion sizes, taxing and prohibiting specialprice deals for junk foods, and placing warning labels on the products.

57.What does the author say about junk food?

A) People should beeducated not to eat too much.

B) It is widely consumeddespite its ill reputation.

C) Its temptation is toostrong for people to resist.

D) It causes more harmthan is generally realized.

58.What do the Rand researchers think of many of the policy measures to controlobesity?

A) They should beimplemented effectively.

B) They providemisleading information.

C) They are based onwrong assumptions.

D) They help people makerational choices.

59.Why do policymakers of alcohol control place density restrictions?

A) Few people are ableto resist alcohol’s temptations.

B) There are already toomany stores selling alcohol.

C) Drinking strongalcohol can cause social problems.

D) Easy access leads tocustomers’ over-consumption.

60.What is the purpose of California’s rule about alcohol display in gas stations?

A) To effectively limitthe density of alcohol outlets.

B) To help drivers togive up the habit of drinking.

C) To prevent possible trafficjams in nearby areas.

D) To get alcohol out ofdrivers’ immediate sight.

61.What is the general guideline the Rand researchers suggest about junk foodcontrol?

A) Guiding people tomake rational choices about food.

B) Enhancing people’sawareness of their own health.

C) Borrowing ideas fromalcohol control measures.

D) Resorting toeconomic, legal and psychological means.

Passage Two

Questions 62 to 66 are based on thefollowing passage.

Kodak’s decision to filefor bankruptcy(破产)protectionis a sad, though not unexpected, turning point for a leading Americancorporation that pioneered consumer photography and dominated the film marketfor decades, but ultimately failed to adapt to the digital revolution.

Although many attributeKodak’s downfall to “complacency(自满),” that explanation doesn’t acknow-ledge the lengths to which the company wentto reinvent itself. Decades ago, Kodak anticipated that digital photographywould overtake film — and in fact, Kodak invented the first digital camera in1975 — but in a fateful decision, the company chose to shelf its new discoveryto focus on its traditional film business.

It wasn’t that Kodak wasblind to the future, said Rebecca Henderson, a professor at Harvard BusinessSchool, but rather that it failed to execute on a strategy to confront it. Bythe time the company realized its mistake, it was too late.

Kodak is an example of afirm that was very much aware that they had to adapt, and spent a lot of moneytrying to do so, but ultimately failed. Large companies have a difficult timeswitching into new markets because there is a temptation to put existing assetsinto the new businesses.

Although Kodakanticipated the inevitable rise of digital photography, its corporate(企业的) culture was too rootedin the successes of the past for it to make the clean break necessary to fullyembrace the future. They were a company stuck in time. Their history was soimportant to them. Now their history has become a liability.

Kodak’s downfall overthe last several decades was dramatic. In 1976, the company commanded 90% ofthe market for photographic film and 85% of the market for cameras. But the1980s brought new competition from Japanese film company Fuji Photo, which underminedKodak by offering lower prices for film and photo supplies. Kodak’s decisionnot to pursue the role of official film for the 1984 Los Angeles Olympics was amajor miscalculation. The bid went instead to Fuji, which exploited itssponsorship to win a permanent foothold in the marketplace.

62.What do we learn about Kodak?

A) It went bankrupt allof a sudden.

B) It is approaching itsdownfall.

C) It initiated thedigital revolution in the film industry.

D) It is playing adominant role in the film market.

63.Why does the author mention Kodak’s invention of the first digital camera?

A) To show its earlyattempt to reinvent itself.

B) To show its effort toovercome complacency.

C) To show its quick adaptationto the digital revolution.

D) To show its will tocompete with Japan’s Fuji photo.

64.Why do large companies have difficulty switching to new markets?

A) They find it costlyto give up their existing assets.

B) They tend to be slowin confronting new challenges.

C) They are unwilling toinvest in new technology.

D) They are deeply stuckin their glorious past.

65.What does the author say Kodak’s history has become?

A) A burden.

B) A mirror.

C) A joke.

D) A challenge.

66.What was Kodak’s fatal mistake?

A) Its blind faith intraditional photography.

B) Its failure to seeFuji photo’s emergence.

C) Its refusal tosponsor the 1984 Olympics.

D) Its overconfidence inits corporate culture.
