Over the last two decades, technology has become part of almost every facet of our lives. The expansion of broadband, smartphones and portable technology has changed how we communicate, access information, work and learn.
While many of these changes are positive, there is growing evidence that this isn’t always the case. In recent years, there has been a gradual shift away from paper-based learning materials in schools toward digital and online tools. This shift accelerated rapidly during the pandemic when almost all schools moved lessons online. Research has shown that this increasing reliance on digital methods and resources may be negatively affecting the ability of students to learn and remember information. There is also growing concern about the impact of digital technology on mental and physical health.
Digital Vs. Paper-Based Materials: Learning
A 2018 meta analysis examined 54 studies involving more than 171,000 readers that compared reading from digital text with reading from printed text. The analysis found that comprehension was better overall when people read printed as opposed to digital texts.
Similarly, a study involving millions of high school students in the 36 countries of the Organization for Economic Cooperation and Development (OECD) found that those who use computers heavily at school “do a lot worse in most learning outcomes, even after accounting for social background and student demographics.” Another analysis revealed that fourth-grade students (approximately 9 to 10 years old) “who used tablets in all or almost all their classes had, on average, reading scores 14 points lower than those who never used them—a differential equivalent to an entire grade level.”
Patricia Alexander, a psychologist at the University of Maryland who studies how we learn, discovered that although students think they learn more reading online, tests show that they actually learn less than when reading print. Part of the problem can be attributed to the speed with which we typically read text on a screen, much of which is easy-to-understand text messages or social-media posts. When it comes to reading more complex information on screen, which requires more attention and thought, people still tend to scan it rather than read it properly.
As well as encouraging us to read quickly, reading online usually involves scrolling, which can make it hard for the brain to create mental maps that help us to remember. When reading a printed book, for example, it’s easy to know roughly which page you’re on, but that’s far more difficult when scrolling through text on a screen. A 2019 study revealed that it’s not just when scrolling that the brain struggles to make mental maps. When a group of 50 participants was asked to read a 28-page story, half of them read a printed version and the other half read the story on an e-reader. Those reading the printed version understood the chronology of the plot better than those reading the digital version. The researchers suggest that “the haptic and tactile feedback of an e-reader does not provide the same support for mental reconstruction of a story as a print book does.”
The benefits of paper-based learning materials aren’t restricted to reading; writing on paper rather than typing on a keyboard can also produce better results. A 2014 study compared the outcome of students taking lecture notes by hand with those who took notes on a laptop. When it came to testing the students on their knowledge of the information, they were allowed to review their notes for 10 minutes before the test. Those who took longhand notes performed better on both factual and conceptual questions.
The authors of the study concluded that “laptop use can negatively affect performance on educational assessments, even — or perhaps especially — when the computer is used for its intended function of easier note taking. For that reason, laptop use in classrooms should be viewed with a healthy dose of caution; despite their growing popularity, laptops may be doing more harm in classrooms than good.”
Perhaps one of the most noticeable differences between reading printed matter compared to reading on a screen is distraction. When reading from a screen, we’re more often than not connected to other services, which bring with them pop-ups and pings from social media, emails and text messages, all of which divert our attention and break concentration. Even in schools, depending on the school’s policy, this can be an issue, particularly when tech-savvy students know how to bypass firewalls and other restrictions.
Digital Vs. Paper-Based Materials: Mental and Physical Health
There is growing concern about the impact of digital devices on mental health, including increased rates of anxiety and depression. With devices now being used by students in school as well as outside the classroom, there is little respite from the constant stimulation they deliver. Paper-based learning materials, in addition to providing cognitive benefits, also provide a much-needed break from the digital world.
A study conducted by researchers at the University of Washington found that students who used paper-based planners were less likely to experience symptoms of anxiety and depression than those who used digital planners. Published in 2017, the study involved 264 undergraduate students who were randomly assigned to use either a paper-based planner or a digital planner. The researchers found that the students who used the paper-based planner reported lower levels of anxiety and depression than those who used the digital planner.
The negative effect of digital devices isn’t limited to their use during the day. The blue light these devices emit also affects how well we sleep. A study conducted by researchers at Harvard Medical School found that those who read from a tablet took longer to fall asleep, had less REM sleep, and felt less rested in the morning than those who read from a paper book.
Poor sleep quality can bring with it a range of negative health consequences. In addition to the effect poor sleep has on mental well-being, it also increases the risk of obesity, diabetes, and cardiovascular disease.
Compared to centuries of paper use, digital and online educational tools are very much in their infancy, with much research still to be done on their impacts. A growing body of research suggests that a switch to electronic learning materials from paper-based materials may be detrimental to students’ ability to learn and remember information, as well as to their overall health and well-being. With healthy, well-educated students as the ultimate goal, perhaps we should slow or even pause the shift to digital materials in schools until we more fully understand their effects on learning and literacy.
The study, commissioned by paper producer Stora Enso, showed 65% of respondents prefer physical books, versus 21% who prefer e-books and 14% audiobooks. The French showed the strongest preference for physical books of any nation. And most said they preferred to read or listen to fiction books for leisure and to get quality time alone.
“These results confirmed our expectations that the market for physical books is set to stay strong, which is good news for our printer and publishing customers,” said Stora Enso’s Jonathan Bakewell, Vice President, Head of Segment Office and Book Papers. But there were some surprise results from the youngest group (16-to-24 year olds) polled, where 70% said they preferred physical books over e-books.
This enthusiasm for books among Gen Zers, who are more likely to be the digital disrupters, seems partially fueled by the manga-book craze, driven by Netflix anime series, as well as a recent explosion in top-selling teen romance books. For older age groups, physical books have been outselling e-books in areas like human potential and mindfulness, particularly during the pandemic as people took pause to look inward.
People have begun rediscovering reading, partly prompted by the pandemic, where many were tethered to their screens all day for work or school, then didn’t want to take them to the sofa when it was time to relax. A majority of respondents (63%) said they read more during Covid, including nearly 70% in the U.K. and U.S. In the youth segment, 64% said they read more and, notably, 76% of young people in the U.S .and 73% in the U.K. During the isolation, the physicality of a book felt more comfortable for some than a digital reader. Some even cited the smell of a physical book that could evoke pleasant memories.
Share of eyes and ears
But even as physical books commanded a larger share of hearts and minds, the study showed there is a time and place for all three book formats, with few respondents saying they stuck to just one. E-books and audio books are more convenient and lighter to carry and can be consumed from multiple devices. And while the book and the e-book are competing for a share of eyes, the audio book is complementary in that it is competing for ears – podcasts, radio, music and other audio media.
Books as carbon storage
Books and the paper they are printed on are circular, and renewable. 42% of readers said they like to keep books when they finish reading them, while 26% loan or donate them. A further 26% sell their books and the remaining 5% recycle or discard them. And while books do emit carbon during production and distribution, they are their own carbon storage units once they’re on our shelves. And it’s important to remember that e-books require energy to manufacture and run their reader devices and to maintain the massive server farms than supply their content.
Carbon neutrality was high on the agenda for most, with 61% of all respondents and 70% of youth saying they would pay more (on average 5.7% of the retail price) for carbon neutral books. A majority would also buy from an outlet that provided carbon neutral or carbon offset books.
Read any good books lately? If so, you’re not alone. In fact, 75% of U.S. adults say they’ve read a book in the past 12 months, a percentage that’s largely unchanged over the past decade. And flipping through the pages of a printed book is still the preferred way to read, according to a recent survey by the Pew Research Center.
Even though there has been a slight uptick in the number of Americans reading e-books, from 25% to 30%, print books remain the most popular format, with 65% of adults saying that they have read a print book in the past year.
Americans read an average (mean) of roughly 14 books during the previous 12 months and the typical (median) American read five books in that period, according to the survey. These figures are identical to 2011, when the Pew Center first began conducting surveys of Americans’ book reading habits.
Despite growth in certain digital formats, only 9% of Americans say they read only digital books (which include audiobooks and e-books) to the exclusion of print and that they have not read any print books in the past 12 months. Some 32% of Americans say they read only print books, while 33% read in digital formats and also read print books.
The Book Manufacturers Institute (BMI) recently commissioned well-known pollster Frank Luntz to find out how parents view the effectiveness of various learning materials, including books, textbooks and workbooks. The most definitive conclusion was that virtually every parent wants physical materials as part of student learning. 85% of parents want physical books in some form, and 88% think they are important and essential learning tools.
In summarizing the study results, Luntz said, “With parents keenly aware of the shortcomings of online learning thanks to the pandemic, this finding is only surprising in its intensity and uniformity. Every demographic and geographic subgroup agrees: printed materials are essential to student learning.”
In the survey of 1,000 parents of K-12 school children across America, the results could not be more conclusive. Parents are deeply focused on what their children learn and, just as important, how they learn it: by a 69% to 31% margin, parents chose physical over online materials when given the option.
In every possible measurement, parents believe physical books will outperform online. From testing results to successful learning, from knowledge retention to focusing on the subject, parents simply believe the physical book is the superior teaching tool.
The survey showed that frustrations with online learning during COVID are real. More than 80% of parents from all backgrounds (including 74% of those who typically favor online materials) believe printed materials would have made their jobs helping their students learn from home easier.
“Parents are more engaged with their children’s education, and they want the help only physical books, textbooks and workbooks can provide,” Luntz said.
Parents cited distractions that students encounter with online materials, such as the ease of surfing the internet during instruction, as the No. 1 concern in moving away from physical printed materials. It’s why parents believe their kids will comprehend better using physical books and why over 70% of parents would prefer their kids hold a book rather than a tablet.
In addition to commissioning the national poll, BMI asked Dr. Naomi Baron, Professor Emerita of Linguistics at American University, to write a whitepaper that summarizes the scientific research around reading print versus digital and how each impacts learning. Dr. Baron explains, “An abundance of research now substantiates that yes, medium matters for learning. While both print and digital have roles to play, the evidence demonstrates the continuing importance of print for sustained, mindful reading, which is critical to the educational process.”
