Digital textbooks open a new chapter
South Korea, one of the world's highest-rated education systems, aims to consolidate its position by digitising its entire curriculum.
By 2015, it wants to be able to deliver all its curriculum materials in a digital form through computers. The information that would once have been in paper textbooks will be delivered on screen.
South Korea's Minister of Education, Science and Technology, Ju-Ho Lee, said that his department was preparing a promotion strategy for "Smart Education", focusing on customised learning and teaching.
The project, launched during the summer, will involve wireless networks in all schools to allow students to learn "whenever and wherever", as well as an education information system that can run in a variety of devices including PCs, laptops, tablets and internet-connected TVs.
He said the government would support an open content market containing a variety of learning materials, aimed at keeping up quality while keeping down costs.
"Smart Education will change how we perceive textbooks," said Mr Lee.
"The transfer from the traditional paper textbooks to digital textbooks will allow students to leave behind their heavy backpacks and explore the world beyond the classroom."
The intended benefits include extending the choice of subjects for students in rural areas who previously have lacked specialist teachers and to make it easier for pupils to study from home.
South Korea's teenagers should be particularly receptive to such educational technology.
An Organisation for Economic Co-ordination and Development (OECD) international assessment found that 15-year-olds in South Korea were the most competent users of digital technologies in a survey of 16 developed countries.
They were best at evaluating information on the internet, assessing its credibility and navigating web pages.
South Korea's pre-eminence has not come about by chance.
Unesco has documented the way that South Korea has carefully controlled the use of information and communication technology (ICT) in education.
The government has understood the importance of having formal standards, so that systems can work with each other and quality can be assured.
The United States, alarmed by its relative international educational decline, is now also increasing the resources it devotes to digital learning.
But its move appears to be an acknowledgement of a lack of joined-up thinking in the past.
President Barack Obama's "Digital Promise", announced last month, involves a new national centre to advance technologies that can supposedly transform teaching and learning.
The remit is "to determine quickly what is working and what is not, and transform today's fragmented learning technology market, paving the way for the widespread use of learning technologies that deliver the best results for students, parents, and teachers".
"With more than 14,000 school districts, and an outdated procurement system, it's difficult for entrepreneurs to break into the market, and it's also tough to prove that their products can deliver meaningful results," the White House said.
Given the way education in the US is so highly devolved there are bound to be continuing questions over how much the initiative can achieve.
Another question is whether technology in the classroom is what really makes a difference.
A study by the Department of Educational Research at Lancaster University found that digital technology in the classroom might help to engage pupils in their learning and could save schools money.
But the Achilles' heel - commonplace with educational technology - was the teachers. They felt they needed far greater training in how to integrate the resources into their lesson plans.
"The sad truth is that students can learn just as badly with a class full of computers, interactive whiteboards and mobile technology as they can with wooden desks and a chalkboard," said science and ICT teacher David Weston, founder of the consultancy Informed Education.
There might be enormous potential for software or gadgets to engage and challenge students in new and imaginative ways.
"But unless there is a focus on developing the teaching expertise to support this then you run the risk of wasting time, money and opportunity," he said.
And it may be that technology is seen as a way to achieve cost savings by - to put it crudely - replacing teachers with robots.
Setting out its Digital Promise ambitions, the White House said: "For years, researchers have been working on developing educational software that is as effective as a personal tutor."
Preliminary results from a US military "digital tutor" project suggested the time needed to become an expert in information technology could be reduced from years to months, said the White House.
"Achieving similar results in subjects such as math would transform K-12 [primary] education." It certainly would.
And although children tend to be quicker on the uptake than their teachers where anything with a screen is involved, this cannot be taken for granted.
The OECD's study of the technology-friendliness of 15-year-olds highlighted crucial differences between printed and digital texts, with their non-linear navigation.
"Individuals who develop the skills needed to use these texts efficiently and effectively will be at an increasing advantage in accessing higher education, finding and succeeding in a well-paid job, and participating fully in society."
So policy makers must guard against creating a new "digital divide" between those who could and who could not use these new technologies, it warned.
But is there a bigger, darker concern about such a centralised digital curriculum? If you put all your educational eggs in one digital basket you might hatch a monster.
An unscrupulous government could relish the fact that everything a child learns is controllable through one, easily manipulated, digital portal.
Such fears have been examined in the novel, The Book, by M Clifford. The US author presents a dystopian civilization in which all information is accessed through an e-reader. The people discover that the digital content has been subtly altered by a corrupt government.
"There is something about paper that commands trust," Mr Clifford said. "And reading is very personal. A bonfire of books used to make us cringe because it represented the destruction of that trustworthy bond."
In an increasingly paperless society, we can trust the technology, but questions need to be raised when governments are involved, he says.
"The scare for me was always the subtlety. The delicate manipulation, one word at a time, to alter someone's perception of the truth.
"Not only is there a fear of changing historical record, but of tailoring someone's perspective on the world. If you think that what you are reading is authentic, then your guard is lowered and you accept it as reality."
He debunks his own dark scenario - but has doubts. "As we've seen, the world is becoming more interconnected on an individual level and so it is unlikely that factual information could be so widely altered. We are probably safe.
"But the fact that it could happen without anyone knowing is the real nail-biter."
