The announcement was met with a sense of anti-climax, though, as many of us rushed to our local library’s website to borrow a Kindle book, only to find that the roll-out is incomplete at this time. No mention of a Kindle title at my public library, for instance, until very late in the week.

Now that the system has propogated, though, folks like me are delighted to see the number of available titles. At my library, for instance, there are over 700 Kindle books with copies available. Wow! How far we have come in the world of e-books in such a short time! And with the Kindle books, the system is set up to allow patrons to have the books they borrow sent directly to their Kindles via wifi (but not 3G–see below). Oh, happy day! Unlike borrowing an ePub book and installing it manually on my Nook, these Kindle books will just appear once I check them out. Ahhh.

For Kindle owners, you will find that checking a Kindle book out from your public library will kick you over to the Amazon site, where you can pick the device you want the book sent to. I just downloaded the limit of four books, and the process works seamlessly. Another example of Amazon winning by offering the most user-friendly interface around.

It is funny to me, though, how developments surrounding the Kindle grab attention to a subject. I mean, before the Kindle itself came out, there had been e-books and e-readers for years, and a devoted crew of intrepid e-bookers who could read stuff on just about anything. But, to the general public, e-books were mostly a nonentity, until Kindle, which, er, kindled interest in e-reading like nothing else. Now that Kindle has turned up at the public library, everyone wants to know what it means, how borrowing works, and how it affects their library or Amazon accounts. Here are the three key facts that you need to know to use the new service:

1. Your library still has to buy books to make them available to library patrons. I read somewhere a reader questioning how many Kindle books would be available for borrowing through the public library. That number is ultimately determined by the number of books that your library purchases through Overdrive and Amazon to make available through the service. Despite all the chatter about new models for publishing and accessing books in the e-book era, the basics of how libraries operate haven’t changed. The library purchases books using its budget and then lends them out to patrons, whether in print or electronic formats. The kerfluffle that arose when Harper Collins told libraries through its distributor Overdrive that their e-books would be limited to 26 circulations was a conflict over terms, not a change in the basic economics of running a library. So, although Amazon makes hundreds of thousand of books available through its store, you will only be borrowing those that your library purchases.

2. The borrowing process is handled through your Amazon account, not through Overdrive or your library. This means, of course, that any patron with a Kindle and without and Amazon account cannot ultimately borrow books from the library. Not a bad deal for Amazon, which makes buying opportunities available during the borrowing process. Given the seamless and slick way that Amazon handles book transmission, this may be a small price to pay. Sometimes the best systems are inherently commercial. Think Apple. It is just a shift from the hardy, noncommercial independence of most public libraries.

3. The books you borrow can only be sent to your Kindle via wifi. It seems like a reasonable limitation, unless you have a Kindle that predates the inclusion of wifi on the device. Those early Kindles will have to be manually loaded–books will have to be downloaded to your computer first and dragged into the documents folder of a Kindle that has been attached via USB to the computer. Hmmm, not ideal. But it reflects Amazon’s growing reliance on wifi over 3G or Whispersync–the new Fire tablet doesn’t even have a 3G option–strictly wifi. So, for older Kindle owners (or should I say, owners of older Kindles), you have now officially caught up with with Sony and all the other devices that have supported this kind of borrowing for years.

But for all the schools that have been investing in Kindles for years, this is a wonderful development. Now the resources of the local public library can be used to augment the school’s collection when it comes to the very activity that seems to boost reading achievement more than anything else. And that secret activity is–drum roll please!–wait for it–reading. Kids who have greater access and greater choice in their reading get better at reading, sometimes really quickly. So, youth of America, obtaining a library card just took on new meaning. Go get one and borrow a book that you want to read on your Kindle today!

Amazon recognizes the problem, according to the article from Reuters: “Undifferentiated or barely differentiated versions of the same book don’t improve the customer experience,” Amazon spokeswoman Sarah Gelman wrote in a June 14 email to Reuters. “We have processes to detect and remove undifferentiated versions of books with the goal of eliminating such content from our store.”

Amazon is to be credited with policing the store to reduce this glut of public domain titles that were easy to list and sell in the past, creating really muddy results for users. Now, the problem is a glut of seemingly useful titles, not redo’s of public domain works, that seem to operate like, well, spam in their attempt to get you to read them, indeed buy them, before you discover that they are essentially advertisements or worse.

From the Reuters article:

Some of these books appear to be outright copies of other work. Earlier this year, Shayne Parkinson, a New Zealander who writes historical novels, discovered her debut “Sentence of Marriage” was on sale on Amazon under another author’s name.

The issue was initially spotted and then resolved by customers through Amazon’s British online forum.

“How did I feel? Shocked and somewhat incredulous, but at the same time, because of the way I found out, very grateful that someone had taken the trouble to let me know,” Parkinson said.

Kindle spam has been growing fast in the last six months because several online courses and, ironically, ebooks have been released that teach people how to create a Kindle book per day, according to Paul Wolfe, an Internet marketing specialist.

One tactic involves copying an ebook that has started selling well and republishing it with new titles and covers to appeal to a slightly different demographic, Wolfe explained.

This is a problem with many tentacles. The very virtues of digital text praised in these posts for over two years become vices when there is no natural way of regulating the proliferation of words. “This is why email spam has become such a problem — it costs nothing” says one expert cited in the article. “If people can put out 12 versions of a single book under different titles and authors, and at different prices, even if they sell just one or two books, they can make money.” For educators, the problems that have arisen regarding the digital distribution of term papers come from the same source. Someone once called the internet “a giant copy machine,” and here is where we see that principle at work.

So what can you do to avoid purchasing a spam book? What characteristics of spam books can you teach your students to look out for in their searches?

Piotr Kowalczyk, self-published author and blogger at eBookFriendly.com, has complied a guide to spam book identification. Here is our summary of his findings and recommendations.

First, take a close look at the title. Is  the title wordy and extensive? If the title of the book seems to be cramming as many keywords in as possible, often displaying the key search terms in all caps, you may have some spam on your hands.

Next, take a look at the author. Does the author seem to write in a variety of topics- from Italian cookbooks to auto mechanics? Authors who seem to be very thinly spread over a variety of topics may also be an indication that the book you are looking at isn’t the one you desire. One should also steer clear of e-books that have no author listed, but instead an editor.

What about the cover? A poorly designed cover that features generic font choices and pixilated images also can serve as a red flag. If the image remains poor quality once enlarged, this often indicates that this image was taken from the web.

The price of the book may also confirm your suspicions. Spam books are often priced at $ 0.99 to entice a reader to purchase the book without downloading a free sample (beware of the free sample: malicious links are often placed in the opening pages of an e-book to ensure their viewing). The price may exceed $ 0.99, but this is a common characteristic of e-book spam that one should take notice of.

Although this next tip may seem obvious, one should still make note of it: the book will often have no Reviews and Ratings, or terrible reviews. Heed these reviews!

However, do not base your decision on the seeming popularity of the text as gauged by the Amazon Bestseller Rank, since people buy these spam book unintentionally and consequently improve the spam’s popularity. When looking on Amazon’s best seller list, however, you may want to notice what categories the book is listed under (unrelated, irrelevant?), and if the text is listed under both books and Kindle Store.

Notice the product description which in cases of spam is often short, poorly written, or a random book excerpt. Look to see if there are any other versions of the e-book available (print, audio). If the e-book is spam, the e-book edition will be your only option. Check the e-book’s file size; spam books have a small file size indicating a short book.

Thanks to Piotr for this helpful analysis. Sadly, even for books, if it’s digital it can be spammed. Knowing the signs of spam-books is just another one of those 21^st-century skills you need to help your students acquire.

1.  Sharing (books among devices on one account)

2.  Lending and Borrowing (books among all users)

3.  Library Lending (books to patrons of the library)

Sharing E-books among Devices on One Account

When Amazon came out with the Kindle, the company realized that book-buyers would want to be able to load their purchases onto more than one reading device. So the company made it possible for customers to load their purchases onto as many as six devices, in most case, if the devices were registered to the same account. As schools began to implement ereader programs, educators saw the benefit of this policy: if a school purchases six or more Kindle, every book they buy can be distributed to six devices, effectively cutting the cost of an already lower-priced e-book by a factor of six. It is like buying six copies for the price of one. And with a little extra management, this “sharing” of books among devices registered to the same account has worked well. Here is how it works for the three major booksellers:

• Amazon Kindle: You can download up to six copies of each book to different platforms.
• Nook/Nook Color: You can download each book within devices on an account, limit six.
• iBooks: You can share among i-devices registered to the same iTunes account. (More info here…)

But…once you have shared the maximum number of times, the sharing stops (at least for Kindle and Nook). This means that once you have assigned the book to the allowed number of devices, those devices “own” those books and they cannot be pulled back into the archive and assigned to other devices. If they could, each book could be downloaded to different devices infinitely, which is clearly not what the publishers want.

Lending E-Books to Someone Not on the Same Account

When the Nook came out, the LendMe feature, which allows anyone to “lend” a book they own to another Nook owner, was unique, but now Amazon has finally matched the feature for Kindle.  Lending an e-book means allowing another reader with the same type of ereader to read a book in your library for two weeks.

But there are rather strict limits to this feature:

1. You can only lend a book once, period.
2. You can only lend for a two week period, period.
3. The book is unavailable to you for the two week lending period, period.
4. Not every e-book is lendable—publishers decide. Period.

Still, this means that an e-book you purchase behaves just a little bit more like a print copy of a book. Heck, half of the books we lend our friends never come back at all!  But consult the purchase details about each book you buy to see if it qualifies for lending. Surveys show that only about half of the e-books you can purchase qualify for lending/borrowing.

So how can I find a book to borrow?

A small cottage industry has sprung up in matching lenders with borrowers. Services to link the two over the Internet began when Barnes and Noble introduced the feature over a year ago, and has gained momentum now that Amazon has joined the party. Here are just a few:

• Kindle Lending Club
• LendInk
• eBookFling

You can read a brief description of each of these services (and more) by clicking here.

Library Lending of E-Books

Finally, there is regular old-fashioned library lending of e-books. Most e-book library lending is based on devices that support Adobe Digital Editions software, which manages the digital licenses that allow books to be distributed to different users for a specified lending period.

Any computer can install the free Adobe Digital Editions software and borrow books from a lending organization, like your local public library. Often, a service like Overdrive is used to manage the whole process, which supports placing a hold on books that are currently checked out. (E-book lending, like physical book lending, restricts the use of the book to one reader at a time.)

For schools, finding a reader that supports library lending and borrowing could vastly expand the number of books available to your students. Right now, among the popular readers, the following do support this feature:

• Nook and Nook Color
• Sony, all models
• iPad (if you install the Bluefire Reader)
• Others, including Android, may be included soon…

So, those are your choices. As I survey the landscape, it seems to me that these strategies offer differing value to educators, so I have ranked them here for your consideration:

• Lending and Borrowing (books among all users) – value to educators? 4 out of 10
• Sharing (books among devices on one account)– value to educators? 8 out of 10
• Library Lending (books to patrons of the library) – value to educators? 9 out of 10

The Kindle is a superb reading platform. But print books also double as serviceable writing platform (score one for the era spawned by Mr. Gutenberg and his press!). And that difference lies at the heart of one difficulty that the Kindle encounters when it enters the classroom. Students want to mark up their books, put sticky notes on important passages, scribble reminders to themselves in the margins. In fact, as a graduate student I actually transferred the marginalia from one copy of Paradise Lost to another for one of my professors. (That exercise provided a terrific window into an expert’s close reading of the text, by the way.) It is hard to circle things, draw arrows, and annotate all over the place on any ereader, Kindle included. So the lack of a robust writing dimension to the Kindle has hobbled it from the get-go for eager, thoughtful students who want to keep what they write right alongside what they’ve read.

Enter Notepad for Kindle. I tried to think of a way that a reader could capture a thought, a reference, or connection and have an easy way to get to it later. The Notepad became a way to do that without exiting the Kindle environment and without burying the idea deep in a book where it might be difficult to find. Now this is no substitute for scribbles, circles, and arrows, but it does bring a measure of organization to the writing process when you have a Kindle in your hand.

Devices with touch technology, like my iPhone or Android phone, have notepad utilities built in or easily downloadable as apps. When I want to harvest a thought, I simply launch the notepad and type it in. Notepad for Kindle is meant to give a similar capacity to those of us who love to read on our Kindles.

BTW, the Notepad is free from the downloads page of this site. Or you can grab a copy yourself by clicking right here.

These calculators became a fixture in our schools, at least for the higher level math and science courses, because they made the process of performing certain calculations much quicker and easier, so that less class time had to be spent on graphing complicated equations manually and more could be spent on teaching and learning about the math behind the graphs. In short, graphing calculators became indispensable because they empowered each student to operate on a more equal footing and they allowed the teacher to spend more time teaching. Nowadays, they are just an expected part of the educational landscape, a $139 appliance that pretty much every serious math student owns and even rushes out to replace if lost or damaged. You just gotta have one.

Since the beginning (and that would be 2007), I have felt that the Kindle or some ereader would achieve a combination of features and price that would make them the graphing calculator of the 21st century. I just didn’t think it would happen so soon.

With its announcement of a next-generation Kindle that connects via wifi and offers improved screen resolution and a bunch of features I still need to read up on, that moment is upon us. You can get a Kindle for the same price as a graphing calculator. Is $139 the ultimate magic number? I don’t know. But I do know that it is a number that has worked for a generation of math students; why won’t it work for this generation of readers? In fact, there is more reason to adopt an ereader like the Kindle because it serves a wider swath of the student population. The graphing calculator supports the curriculum at one, fairly specialized level in K-12 education; the Kindle supports multiple subjects from the least to the most advanced levels. I just don’t think folks have connected the dots on this one yet. And $139 is within shouting distance of the $99 price point that market pundits and the general public agree will ignite mass adoption of the devices.

Bezos and company seem intent on making the Kindle the device at the center of that mass adoption and, with the head-spinning rapidity with which they are lowering the price and adding options, I think that they might just be on to something.

Where do you get the serial number? Well, it is printed in extremely small print on the back of each device (have your magnifying glass handy if you look there), so Kathy takes the serial number off the box each Kindle came in. This is why it’s important to keep the Kindles numbered from the beginning, and also to jot the number on the box itself when you put the sticky on the Kindle. (Kathy keeps the box associated with each Kindle around in case the Kindle has to go back–apparently Amazon likes it that way.)  Ugh.

OK, anyway, now it is time to put that serial number from the box into the Manage My Kindle page at the mother ship, which will enable Kathy to track her content downloads to specific devices, even if it is a broken Kindle that a student has brought back to her. Registered properly, “Kathy’s 53rd Kindle” will mean the same thing to Amazon as it does to Kathy, and as it does to the student who has it in her bookbag. It is time for Kindle to Phone Home.

If this is beginning to sound like an assembly line operation, well, that’s because it is. Sitting at her desk, Kathy calls out for one of the helpers to bring her a stack of charged and stickered Kindles. Not just any stack, but the one with the next Kindle number in her system. Why? Because when Kathy registers the next Kindle, Amazon will assign it the next number in its sequence, meaning that if Amazon knows that Kathy has 52 Kindles, the next one she registers will become “Kathy’s 53rd Kindle” by default. No time for confusion this. The conversation goes as follows:

Kathy: I’m ready for more Kindles!

Helper: What number are you on?

Kathy: 54.

Helper: You have Kindle 54 or you need Kindle 54?

Kathy: I need Kindle 54.

Helper: Ok, who has Kindle 54?

Helper 2: I think its on the table by the door.

Helper: No, this says Kindle 78.

Helper 2: Maybe it’s in the server room.

Helper: I’ll look.

You get the picture. Registering the Kindle that has the number 55 on its back in the 54th position, a misstep with grave consequences if not noticed immediately, is to be avoided at all costs. So an orderly exchange of Kindles is essential at the moment of registration.

On the Manage My Kindle page, Kathy scrolls down to the “Register a new Kindle” link at the bottom of her list of Kindles and clicks it, opening a text box into which she can type the serial number from the box. Sixteen digits in, a push of the button, and that Kindle is officially connected to home base. Kindle Phoned Home. On to the next. Eighty times. Ugh.

But, you know, it was kind of fun. Kathy is so enthusiastic about the benefit to her kids that the time flies with smiles all around. In May, Kathy put out a tweet about how much the Kindles meant to the kids at her school this year:

8th grader 2 mention being first “Kindle 8th Graders” in her commencement speech tonight. Jeff Bezos you impacted ed.

Whether you meant to or not, Jeff Bezos, you impacted ed.

Well, Amazon’s consumer bias also makes setting up multiple devices a chore for folks like Kathy. The system is designed to work with a single device, or a few that a family might have on a single Amazon account. So, setting up 80 Kindles at a time involves repeating a process that a consumer might do once eighty times in a row. And that’s before you even start downloading books to the devices, another serial process that must be repeated 80 times for each book you want to put on all the Kindles.

But all of this didn’t seem to disturb good-natured Kathy, pictured above with the author, near the table where a dozen of the new Kindles were receiving their first charge. Kathy immediately starts the charging process once she gets the Kindle boxes open so that she can tell right away if there is a defective Kindle among the bunch. So far, on this shipment, she has only found one, which Amazon will quickly replace.

As she sets the Kindles up for charging, Kathy also numbers the Kindles with a sticky note. This step accomplishes a few things. First, it creates the first identifier that Kathy will use to record the Kindle in her district inventory. Second, it tells Kathy where each Kindle stands in the queue to be registered in her Kindle account at Amazon. Linking the physical number of the Kindle to the name that the Kindle will ultimately hold in the Amazon system (e.g. “Kathy’s 52nd Kindle,” visible at the top of each device’s Home screen) is key to managing content on the individual Kindles once they are in the hands of students.

But I have gotten a step ahead of myself. You can’t get to this stage until you have opened up each Kindle’s packaging by pulling the little tab across the end of the tight little box the Kindles come in. (Anyone remember the big, white book-like enclosures for the first generation of Kindles?) Kathy’s assistant in the process, husband Steve (himself principal of a nearby school that is using Kindles), showed me what a chore that is, since the tabs don’t really sit up where you can pull on them. For this batch of Kindles, at least, a fingernail couldn’t quite do the job (and I tried it myself!). Steve discovered that some kind of implement is required–a letter opener or pocket knife–to lift the tab so the sealing strip can be pulled off and the Kindle liberated for use. This seems like a small thing but, repeated eighty or a hundred times, it adds a significant step to the batch processing of Kindles for student use.

Once the Kindles are opened, labeled, and charged, they are ready to be registered with Amazon. The details of that procedure will follow in Part 2 of this post.

The findings are clear. Researchers report:

• the students improved between 41% and 70% on their SRA Reading scores after one year of large print remediation, gains that continued during summer breaks, unlike the typical loss from regular print books

• because there are fewer words and those words are easier to decode, struggling readers make substantial progress with comprehension, tracking, and fluency, all while making fewer decoding mistakes. Additionally, research shows that fewer words on the page lower anxiety levels in struggling readers

• at least one aspect of format — font size or style — was an important factor for 70% of the children when making book selections. Statements by the children regarding font revealed that they based their book selections on the legibility of the text

• students were able to read books on a higher reading level when the books were Large Print, as opposed to only being able to read on- or below-grade level books in regular print.

These are pretty compelling findings, especially given that original research was undertaken to specifically test the value of large print books for comprehension, fluency, and vocab development. The paper offers considerable ammunition for schools seeking grants to offer larger fonts to students in all phases of their academic and pleasure reading.

Should I get a bunch of Kindles for my school? It’s a question the answer to which is up in the air. A bunch of iPads? Still in doubt. Here’s the real question: should I be taking advantage of the properties of digital text in my teaching? The answer to that one is unequivocal, and the answer is yes.

OK, you say, digital text has been around for a long time. What’s the big deal right now? The answer to that one is easy, too: the emergence of dedicated mobile reading platforms, like the Kindle and the iPad (and the iPhone, and the Sony Reader, and the Nook). Digital text has been available for a long time in one form, primarily, and that is formatted as HTML and viewed on a computer monitor. (In fact, it is indicative of this history that 50% of ebooks today are read on a computer, even with the proliferation of choices in mobile readers.)

So what’s different now? For the first time we have devices and software that are dedicated to taking advantage of the virtues of digital text. My quick list of those virtues includes:

• variable text size
• variable type face
• distribution of text electronically
• availability of free text
• storage requirements for digital text
• amount of the world’s knowledge already captured in digital text
• user control of digital text
• the sustainability of digital text
• fresh formats for prose enabled by digital text

In this and the next few posts, I am going to discuss  these virtues and link them to what we know about how students learn. First up, variable text size.

Digital Text: The Advantage of Variable Font Size for Reading

Something that has been widely reported is the pleasure that a lot of people take in reading text on the Kindle at a larger font size than is typical for them. That is certainly true for me; I am a declared lover of Kindle Font Size #4 which, as it turns out, is roughly equivalent to a 14 point font. In an unscientific survey I conducted on this blog a while back, 70% of the participants indicated a preference for Kindle Font Size #3 or higher. While this was a very small sample, the preference for larger font sizes was clear.

In the meantime, students have put their thoughts on the record about font size, and bigger is certainly preferred by the middle school students polled by Kathy Parker at Seneca (IL) Middle School, where Kathy has run a Kindle pilot program this past school year. They like the largest font size, period. They say it helps them read better.

Recently, a blogger in the UK noted that reading text on his iPhone was easier than in books or other settings. Why? A bit of investigation told him that larger fonts reduce the amount of print on the page; words are less jammed together. The blogger, it turns out, is dyslexic, and receives this diagnosis of the situation validated by a prominent neuroscientist, who comments that “Many dyslexics have problems with ‘crowding’, where they’re distracted by the words surrounding the word they’re trying to read.”

I did a little research myself on the “crowding” phenomenon, which has been carefully studied by researchers here and abroad, especially as it affects the reading rate of “normal” and “dyslexic” readers. The findings across many studies are clear:

• all readers benefit from increasing text size up to a maximum, after which increased reading rate associated with the larger text flattens out
• the optimal font size for “normal” readers is larger than average, but not as large as it is for dyslexic readers
• much of the reading rate difference between normal and dyslexic readers can be mitigated through increased font size

In a Research Brief I wrote recently on the subject, I provide an overview of “crowding”: “In the research, crowding specifically refers to “the difficulty in identifying a letter embedded in other letters” (Chung, 2007). Studies have shown that the crowding effect impacts reading rates in both the horizontal and vertical proximity of text, so that larger font size creates more space between adjacent letters in the text, and may increase line spacing as well, reducing crowding.”

I have also summarized the findings of a number of studies. For example, a 2009 study conducted at the University of Rome, Italy, tells us that for both the control and experimental groups, “…the reading rate increased with print size up to a maximum. In dyslexics, the fastest rate was obtained at a significantly larger character size than in controls” (Martelli, DiFilippo, Spinelli, and Zoccolotti, 2009).

You can read or download a copy of the study in PDF format right here.

And if the research doesn’t persuade you, maybe the words of the middle schoolers who have reported on their Kindle-enabled reading will:  “The font that everyone prefers to use with the Kindle 2 is the largest font size.”

Let me explain. Amazon makes it possible for you to read a book that you have purchased on whatever reading device that you happen to have with you at any time, as long as two requirements are fulfilled:

Requirement 1: Amazon software must be installed on all reading devices.
Requirement 2: An internet connection must be present.

When these two requirements are met, Amazon allows you to access your whole library of books that you have purchased through the Kindle store no matter where you am or what device you happen to have with you at the time.

Very cool.

For me, it means being able to fire up Drive or How We Decide or Iconoclast while waiting for a haircut or for a movie. My Michael Connelly novel is with me during rain delays and long lines at the supermarket. Synchronization means that I have achieved a state of multiple-platform nirvana wherein all my books are with me all the time.

Even better, I don’t have to remember what page I was on in any of them. The mother ship at Amazon always offers to “synch to furthest page read” when I open a book on a different device than the one I was reading on last time. This way, I never lose my place and the reading experience becomes, as Jeff Bezos would say, “frictionless.”

Except when my wife is reading the same book on her Kindle. Then, the “furthest page read” may not be MY furthest page read; rather, it may be HER furthest page read. The synchronization feature also means that her highlights appear in “my” copy of the book. In this case, the ability to share books among multiple Kindles/devices registered to the same account creates a conflict with the ability to synchronize one’s reading among those various devices.

This conflict raises a special problem for teachers who may be leveraging the ability to load books on multiple devices and make more texts available to more students for the same price. What to do?

I only recently learned that you can “de-synchronize” the Kindles and other devices registered to a single account, and if the downside of synchronization is just too great–Josh keeps underlining all the text in everybody’s copy of Old Yeller–then it is easy to take care of the problem.

Just go to the page at Amazon called “Manage My Kindle” and scroll to the bottom, where you will see a link named “Manage synchronization between devices.” This is where you will find the following guidance from the Amazon team (see below, #1):

“You should turn synchronization off only if:
* You and someone else are reading the same book, AND
* The Kindles are registered to a single account”

The recommendation seems sound, if a little bossy. So many advantages of the Amazon Kindle system flow from the synchronization feature that it only makes sense to keep it on (which is the default setting) unless it is creating a problem for you.

If you decide to “de-synchronize” because you want each device in the classroom (or at the house) to operate independently of the others, then look for the button on the right that allows you to “Turn Synchronization Off” (see illustration, #2).

Click for larger image

Remember, teachers, that turning off synchronization does not in any way interfere with your ability to load books onto Kindle, or with the students’ ability to highlight passages or make notes. Those highlights and notes will simply be stored “locally,” saved only on the specific Kindle on which they were made. They can still be accessed by your or the students by tethering the Kindle to a computer with the USB cord and accessing the text file where those notes and highlights are stored.

Now, sometimes it might be cool to have multiple students commenting and highlighting a book across multiple devices. That might even become a best practice for Kindle/ereader use in the classroom. A literature circle or book club of kids take on a read together, share their notes and highlights, and then each create a summary piece of writing explaining a passage or two that received particular attention from the group. Or make the marked up text a group project, finding six passages that seem significant and each making a comment that the teacher could read and respond to or even grade.

Hint: one special power of the synchronization feature is that the highlights and comments that are made in the text by an individual or a group are available for viewing online here after login. Sign in and look at the column to the right; there you will find a icons for “Highlights” and “Notes.” Students could be required to put their name at the end of each note they create, and the teacher could browse these notes easily without have the Kindles handy or any file transfer reqquired.

So, in the end, whether you keep your devices synchronized or not just “depends” on the kind of reading experience multiple readers on a single Amazon Kindle account want to have.
