Authors and publishers of academic textbooks need to take a serious look at an emerging behavioural characteristic of students – their obsession with the smartphone. Smartphones, particularly Social Media, has become a major distraction for students while studying, even in the classrooms.
Another major behavioural change is the way students absorb knowledge. With continuous access to rich media such as videos, interactive graphics, and music, reading only static text and diagrams has become dull for students.
Keeping these behavioural changes in mind, authors and textbook publishers need to figure out a way to make their content more interesting and dynamic in nature. A cost-effective way to do this is to use QR Codes inline with content.
What are QR Codes?
QR Codes are 2D barcodes that link smartphones to online content. Users can scan QR Codes using their smartphones and view dynamic online content such as websites, Youtube videos, audio, animations, and photo galleries.
QR Codes are widely common and regularly appear in newspaper/magazine ads, products, flyers, and business cards.
QR Codes can be generated using an online QR Code Management tool and scanned using freely-available QR Code scanning applications. A lot of teachers and publishers are already using them to engage students.
How can authors use QR Codes in books?
Here are 5 ways of using QR Codes in books:
1. Show an explainer video instead of static images
You can support your text by adding QR Codes to show explainer videos, wherever applicable.
For example, Al Trujillo, a Distinguished Teaching Professor of Earth Sciences at Palomar College in San Marcos, California uses QR Codes for this use case:
“There is a QR code in the text that links to a video showing how oceanographic equipment that got stuck on the sea floor in an active lava flow was later retrieved. So now, instead of students just reading the story and seeing a static picture, they get to view a video and hear me describe the recovery of the equipment” – Al Trujillo

2. Save pages by linking QR Code to online photo galleries
Publishers can reduce printing costs by removing images of low importance and a QR Code that links to a photo gallery of these images. This way authors can ensure that the most important images are printed and if the students want more information, they can scan a QR Code to see the supplementary images.
Images can be uploaded on free image hosting sites and the image URL can be added to the QR Code.
3. Conceal solutions in QR Codes
For end-of-chapter problems, the author can conceal the answers in a QR Code. They can either link a full-length answer with solution or simply add the final answer in a Text QR Code (A simple text QR Code encodes the information in the code itself and does link to any URL online).
4. Run polls, comments, or surveys on content
Authors can make learning fun by introducing an element of collaboration. For a thought piece in the textbook, the author can invite comments or votes by the readers. Readers will simply need to scan the QR Code, add a text comment, and also read what readers have to say.
5. Provide audio translations for language books
This use case is specifically for language studies authors. In addition to providing text pronunciation, authors can also provide audio pronunciation by adding a QR Code that links to an online audio file.
How can authors/publishers set this up?
There are two ways to do add and use QR Codes to textbooks:
1. Standalone-QR Codes that direct readers to online content
Authors can use a QR Code management tool to generate dynamic QR Codes that will direct users to online content. The advantage of using dynamic QR Codes is that the authors have a choice of updating the destination URL in case they wish to change content without the need to change the QR Code in the text book.
The QR Codes will have to be created one by one and will have to be managed by either the publisher or the author. The advantage is that authors can get started right away in a very cost-effective way. Readers can use any standard QR Code scanning mobile application.
In 2013, Vodafone launched a digital library, Biblioteca digitală, in Romania as part of a marketing campaign. The library allowed users to add books to their virtual bookshelf and order it as a wallpaper.
When posted on the wall, the wallpaper would become the reader’s personal library.
Each book on the wallpaper shelf came with a QR Code printed on it. Scanning the QR Code would allow readers to read the book on their smartphones or tablets.
2. Develop a custom mobile application to read static QR Codes
If you are a publisher and planning to use QR Codes in many of your books, then this is a much cost-effective way in the long run. You can design a custom application which readers will need to download. Each QR Code in the text book will contain a unique alphanumeric code which can be read by the custom app.
The advantage of a custom app is that readers can save files and links for offline reading.
Popular textbook publisher in India, S. Chand Publishing, uses a custom app ACTION for this purpose.
