Tablets vs. Textbooks - ProCon.org http://bit.ly/NPdUTQ
Tablets-Textbooks ProCon.org is a nonpartisan, nonprofit website that presents facts, studies, and pro and con statements on whether or not tablets should replace textbooks in K-12 schools
Publishing for the K-12 school market is an $8 billion industry, with three companies - McGraw-Hill, Pearson, and Houghton Mifflin Harcourt - capturing about 85% of this market.  Tablets are a $72 billion industry with 42% of US adults owning a tablet.  As tablets have become more prevalent, a new debate has formed over whether K-12 school districts should switch from print textbooks to digital textbooks on tablets and e-readers.
Proponents of tablets say that they are supported by most teachers and students, are much lighter than print textbooks, and improve standardized test scores. They say that tablets can hold hundreds of textbooks, save the environment by lowering the amount of printing, increase student interactivity and creativity, and that digital textbooks are cheaper than print textbooks.

Opponents of tablets say that they are expensive, too distracting for students, easy to break, and costly/time-consuming to fix. They say that tablets contribute to eyestrain, headaches, and blurred vision, increase the excuses available for students not doing their homework, require costly Wi-Fi networks, and become quickly outdated as new technologies are released.
2012 marked the first time that more people accessed the Internet via smartphones and tablets than desktop or laptop computers.  By Jan. 2014, 42% of US adults owned a tablet computer, 32% owned an e-book reader, and 50% owned one or the other (up from 29% in Aug. 2012), according to a survey by the Pew Research Internet Project.  Approximately 227 million tablets were shipped in 2013, and that number is projected to increase to 386 million by 2017.  A joint report by McKinsey and the GSMA predicts the mobile education market could be worth $70 billion globally by 2020, and predicts demand for mobile education devices, like smartphones and tablets, may be worth another $32 billion by the same time frame. 
43% of Americans read online books, magazines, or newspapers.  Amazon announced in July 2010 that e-books were outselling paper books, and a July 2012 report by the Association of American Publishers showed that e-book revenue exceeded that of hardcover books for the first time ever.  From 2008 to 2012, e-book sales rose from $68 million per year to $3 billion.  While e-books sales rose 117% from 2010 to 2011, the print book business declined 2.5% in 2011 to $27.2 billion from $27.9 billion in 2010.  However, over 90% of educational textbooks are still read on paper, and only 30% of textbook titles are available electronically. 
In Nov. 2010, the US Department of Education released its National Education Technology Plan, a detailed blueprint on how schools can improve learning with technology. Among its recommendations is to leverage mobile devices ("the technology students already have") in the classroom. In his Jan. 2011 State of the Union address, President Obama said, "I want all students to be able to learn from digital textbooks." On Feb. 1, 2012, the US Department of Education and the Federal Communications Commission (FCC), in collaboration with several tech organizations, released a downloadable "Digital Textbook Playbook" to "encourage collaboration, accelerate the development of digital textbooks and improve the quality and penetration of digital learning in K-12 public education."

99,000 K-12 schools spend $17 billion annually on instructional materials and technology. Many districts, schools, and states have begun transitioning their instructional materials from paper textbooks to digital learning environments, according to the "Digital Textbook Playbook." Florida has mandated that all K-12 instructional materials are required to be provided in electronic format by 2015-2016. California launched a free digital textbooks initiative in 2009, and West Virginia replaced social studies print textbook purchases with digital textbooks. Georgia state law requires that electronic copies of K-12 textbooks be made available for use by students, and the San Diego Unified School district has distributed 78,000 digital textbooks to teachers and students since 2011 and purchased 26,000 iPads for district use in June 2012.  In June 2013, the Los Angeles Unified School District (the second-largest school district in the country) approved a $1 billion plan to purchase 655,000 iPads for all the K-12 students in the district. 
The percentage of K-12 classrooms with internet access has increased from 51% in 1998 to 98% in 2012, and 40% of elementary school teachers use computers during in-class instruction. Several meta-studies on the use of computer technology in the classroom show a small but statistically significant increase in learning outcomes.  Nineteen percent of children ages 2-5 in the United States, Canada, Japan, Australia, New Zealand, Czech Republic, France, Spain, Italy, Germany, and the UK can use a smartphone application. By comparison, 9% can tie their own shoelaces. More children ages 2-5 can open a web browser (25%) than swim unaided (20%). 20% of children ages 6-9 use email, and 14% are on Facebook.  A study by Nielsen Mobile Insights found that 53% of blacks and 57% of Latinos are smartphone users, well above the 45% rate of non-Hispanic whites.  Blacks and Hispanics are more than twice as likely to use Twitter and rely on mobile phones as a primary connection to the Internet than whites. 
The American Association of Publishers says that the average net unit price of a K-12 print textbook was $65 in 2010.  A 2005 report by Congress' Government Accountability Office found that print textbook prices nearly tripled from 1986 to 2004, rising at twice the rate of inflation.  A report from the Student Public Interest Research Group found that textbook wholesale prices have risen nearly four and a half times the rate of inflation from 1990-2009.  Digital textbooks on average cost 50-60% less than new print textbooks. Tablets in the United States cost on average $489 in 2011, $386 in 2012, $343 in 2013, and are projected to cost $263 in 2015.  However, implementation costs for e-textbooks on iPad tablets are 552% higher than new print textbooks in an average high school, and the annual cost per student per class with tablets is $71.55 vs. $14.26 for print textbooks.  This difference is due to additional costs associated with building wi-fi infrastructure, training teachers and administrators how to use the technology, and annual publisher fees to continue using e-textbooks.

According to an Apr. 2012 peer-reviewed study in Archives of Disease in Childhood, the average weight of a student's backpack is 15.4 pounds (an average of 3-4 books), and the average weight of a tablet is between 0.75 to two pounds.  Pediatricians and chiropractors recommend that students not carry more than 15% of their body weight in a backpack, but an Apr. 14, 2004 study by the State of California found that the combined average weight of textbooks in just the four core subjects of History-Social Science, Mathematics, Reading/Language Arts, and Science exceeded this percentage at nearly all grade levels from 1-12.  According to data from the United States Consumer Product Safety Commission, over the period from 1994-2000 more than 23,000 youths ages 6 to 18 were treated in emergency rooms for backpack-related injuries, such as contusions, sprains and strains to the back and shoulders, and fractures. California and Georgia are the only states with legislation related to textbook size and weight, according to the Association of American Publishers.  In California, the maximum weight for a textbook is three pounds for grades K-4, four pounds for 5-8, and five pounds for 9-12.

- A 4GB tablet filled with 3,500 e-books weighs a billionth of a billionth of a gram more than if it were empty of data - a difference that is approximately the same weight as a molecule of DNA. The same number of physical books would weigh about two tons. 
- In San Francisco, New York, and Los Angeles, robberies related to internet-enabled handheld devices (including tablets) have accounted for 50, 40, and 25 percent respectively of all robberies in 2012. 
- Manufacturing one tablet requires the extraction of 33 pounds of minerals, 79 gallons of water, and 100 kilowatt hours of fossil fuels resulting in 66 pounds of carbon dioxide. 
- Students who used an interactive, digital version of an Algebra 1 textbook for Apple's iPad in California's Riverside Unified School District in 2012 scored 20 percent higher on standardized tests vs. students who learned with print textbooks. 
- During the 2011-12 school year more than 13,700 US children, aged 5 to 18, were treated in hospitals and doctors' offices for backpack-related injuries (5,000 in emergency rooms) such as contusions, sprains, fractures, and strains to the back and shoulders.
