Warning for Food Colorings to Be Considered by F.D.A. Panel - NYTimes.com - 0 views

  • The hearings signal that the growing list of studies suggesting a link between artificial colorings and behavioral changes in children has at least gotten regulators’ attention — and, for consumer advocates, that in itself is a victory. In a concluding report, staff scientists from the F.D.A. wrote that while typical children might be unaffected by the dyes, those with behavioral disorders might have their conditions “exacerbated by exposure to a number of substances in food, including, but not limited to, synthetic color additives.”

Yglesias » Half Of Adults In Detroit Are Functionally Illiterate - 15 views

  • the fact that huge numbers of kids are passing through school systems and not learning basic literacy drives home the fact that districts also need to take checking to see if the kids are learning anything more seriously. That means tests, and since it’s good to be able to compare different schools to one another that means standardized tests. It’s a limited tool, it shouldn’t be the sole criterion on which the effectiveness of anything is measured, but it’s also an important one.

Get the Most out of Online Quizzes « classroom2point0 - 156 views

  • Unfortunately, life is not multiple choice; it’s a story problem. If we want to prepare our students for the demands of college and the real world, we cannot afford to whittle away their knowledge to a, b, c, d, or e: all of the above. At the same time, our time as teachers is at a premium and very few of us can afford to spend hours grading essay tests.

Many US schools adding iPads, trimming textbooks - Yahoo! Finance - 4 views

  • The trend has not been limited to wealthy suburban districts. New York City, Chicago and many other urban districts also are buying large numbers of iPads.The iPads generally cost districts between $500 and $600, depending on what accessories and service plans are purchased.By comparison, Brookfield High in Connecticut estimates it spends at least that much yearly on every student's textbooks, not including graphing calculators, dictionaries and other accessories they can get on the iPads.
  • They include interactive programs to demonstrate problem-solving in math, scratchpad features for note-taking and bookmarking, the ability to immediately send quizzes and homework to teachers, and the chance to view videos or tutorials on everything from important historical events to learning foreign languages.They're especially popular in special education services, for children with autism spectrum disorders and learning disabilities, and for those who learn best when something is explained with visual images, not just through talking.Some advocates also say the interactive nature of learning on an iPad comes naturally to many of today's students, who've grown up with electronic devices as part of their everyday world.

Teachers - Will We Ever Learn? - NYTimes.com - 182 views

  •  
    I get very tired of having people point to Singapore as a good model for education. Singaporeans score well on tests because their life depends on it. Doing poorly on the PSLE taken at the end of sixth grade virtually guarantees you will never attend university and will limit your income for the rest of your life. Parents in Singapore spend thousands every year on private tuition, the sole goal of which is to produce high test scores. Singapore also recognizes that they are not producing creative students. In fact they wish they were more like the US.

Bing in the Classroom will eliminate adverts at no cost to school districts | eSchool N... - 23 views

  • Schools are safe havens where children should be able to learn and grow in a supportive atmosphere. At home, parents have the ability to monitor their children’s intake of consumer products by limiting television and internet usage, and helping them engage critically with the content they see. But if we allow advertising in any form in our schools, we run directly counter to the message educational institutions are trying to promote: that these are places of learning, not selling.

Occupy Your Brain - 111 views

  • One of the most profound changes that occurs when modern schooling is introduced into traditional societies around the world is a radical shift in the locus of power and control over learning from children, families, and communities to ever more centralized systems of authority.
  • Once learning is institutionalized under a central authority, both freedom for the individual and respect for the local are radically curtailed.  The child in a classroom generally finds herself in a situation where she may not move, speak, laugh, sing, eat, drink, read, think her own thoughts, or even  use the toilet without explicit permission from an authority figure.
  • In what should be considered a chilling development, there are murmurings of the idea of creating global standards for education – in other words, the creation of a single centralized authority dictating what every child on the planet must learn.
  • ...26 more annotations...
  • In “developed” societies, we are so accustomed to centralized control over learning that it has become functionally invisible to us, and most people accept it as natural, inevitable, and consistent with the principles of freedom and democracy.   We assume that this central authority, because it is associated with something that seems like an unequivocal good – “education” – must itself be fundamentally good, a sort of benevolent dictatorship of the intellect. 
  • We endorse strict legal codes which render this process compulsory, and in a truly Orwellian twist, many of us now view it as a fundamental human right to be legally compelled to learn what a higher authority tells us to learn.
  • And yet the idea of centrally-controlled education is as problematic as the idea of centrally-controlled media – and for exactly the same reasons.
  • The First Amendment of the U.S. Constitution was designed to protect all forms of communication, information-sharing, knowledge, opinion and belief – what the Supreme Court has termed “the sphere of intellect and spirit” – from government control.
  • by the mid-19th century, with Indians still to conquer and waves of immigrants to assimilate, the temptation to find a way to manage the minds of an increasingly diverse and independent-minded population became too great to resist, and the idea of the Common School was born.
  • We would keep our freedom of speech and press, but first we would all be well-schooled by those in power.
  • A deeply democratic idea — the free and equal education of every child — was wedded to a deeply anti-democratic idea — that this education would be controlled from the top down by state-appointed educrats.
  • The fundamental point of the Occupy Wall Street movement is that the apparatus of democratic government has been completely bought and paid for by a tiny number of grotesquely wealthy individuals, corporations, and lobbying groups.  Our votes no longer matter.  Our wishes no longer count.  Our power as citizens has been sold to the highest bidder.
  • Our kids are so drowned in disconnected information that it becomes quite random what they do and don’t remember, and they’re so overburdened with endless homework and tests that they have little time or energy to pay attention to what’s happening in the world around them.
  • If in ten years we can create Wikipedia out of thin air, what could we create if we trusted our children, our teachers, our parents, our neighbors, to generate community learning webs that are open, alive, and responsive to individual needs and aspirations?  What could we create if instead of trying to “scale up” every innovation into a monolithic bureaucracy we “scaled down” to allow local and individual control, freedom, experimentation, and diversity?
  • The most academically “gifted” students excel at obedience, instinctively shaping their thinking to the prescribed curriculum and unconsciously framing out of their awareness ideas that won’t earn the praise of their superiors.  Those who resist sitting still for this process are marginalized, labeled as less intelligent or even as mildly brain-damaged, and, increasingly, drugged into compliance.
  • the very root, the very essence, of any theory of democratic liberty is a basic trust in the fundamental intelligence of the ordinary person.   Democracy rests on the premise that the ordinary person — the waitress, the carpenter, the shopkeeper — is competent to make her own judgments about matters of domestic policy, international affairs, taxes, justice, peace, and war, and that the government must abide by the decisions of ordinary people, not vice versa.  Of course that’s not the way our system really works, and never has been.   But most of us recall at some deep level of our beings that any vision of a just world relies on this fundamental respect for the common sense of the ordinary human being.
  • This is what we spend our childhood in school unlearning. 
  • If before we reach the age of majority we must submit our brains for twelve years of evaluation and control by government experts, are we then truly free to exercise our vote according to the dictates of our own common sense and conscience?  Do we even know what our own common sense is anymore?
  • We live in a country where a serious candidate for the Presidency is unaware that China has nuclear weapons, where half the population does not understand that Saddam Hussein had nothing to do with 9/11, where nobody pays attention as Congress dismantles the securities regulations that limit the power of the banks, where 45% of American high school students graduate without knowing that the First Amendment of the Constitution guarantees freedom of the press.   At what point do we begin to ask ourselves if we are trying to control quality in the wrong way?
  • Human beings, collaborating with one another in voluntary relationships, communicating and checking and counter-checking and elaborating and expanding on one another’s knowledge and intelligence, have created a collective public resource more vast and more alive than anything that has ever existed on the planet.
  • But this is not a paeon to technology; this is about what human intelligence is capable of when people are free to interact in open, horizontal, non-hierarchical networks of communication and collaboration.
  • Positive social change has occurred not through top-down, hierarchically controlled organizations, but through what the Berkana Institute calls “emergence,” where people begin networking and forming voluntary communities of practice. When the goal is to maximize the functioning of human intelligence, you need to activate the unique skills, talents, and knowledge bases of diverse individuals, not put everybody through a uniform mill to produce uniform results. 
  • You need a non-punitive structure that encourages collaboration rather than competition, risk-taking rather than mistake-avoidance, and innovation rather than repetition of known quantities.
  • if we really want to return power to the 99% in a lasting, stable, sustainable way, we need to begin the work of creating open, egalitarian, horizontal networks of learning in our communities.
  • They are taught to focus on competing with each other and gaming the system rather than on gaining a deep understanding of the way power flows through their world.
  • And what could we create, what ecological problems could we solve, what despair might we alleviate, if instead of imposing our rigid curriculum and the destructive economy it serves on the entire world, we embraced as part of our vast collective intelligence the wisdom and knowledge of the world’s thousands of sustainable indigenous cultures?
  • They knew this about their situation: nobody was on their side.  Certainly not the moneyed classes and the economic system, and not the government, either.  So if they were going to change anything, it had to come out of themselves.
  • As our climate heats up, as mountaintops are removed from Orissa to West Virginia, as the oceans fill with plastic and soils become too contaminated to grow food, as the economy crumbles and children go hungry and the 0.001% grows so concentrated, so powerful, so wealthy that democracy becomes impossible, it’s time to ask ourselves; who’s educating us?  To what end?  The Adivasis are occupying their forests and mountains as our children are occupying our cities and parks.  But they understand that the first thing they must take back is their common sense. 
  • They must occupy their brains.
  • Isn’t it time for us to do the same?
  •

The Reading Brain in the Digital Age: The Science of Paper versus Screens - Scientific ... - 25 views

  • The matter is by no means settled. Before 1992 most studies concluded that people read slower, less accurately and less comprehensively on screens than on paper. Studies published since the early 1990s, however, have produced more inconsistent results: a slight majority has confirmed earlier conclusions, but almost as many have found few significant differences in reading speed or comprehension between paper and screens. And recent surveys suggest that although most people still prefer paper—especially when reading intensively—attitudes are changing as tablets and e-reading technology improve and reading digital books for facts and fun becomes more common.
  • Compared with paper, screens may also drain more of our mental resources while we are reading and make it a little harder to remember what we read when we are done. A parallel line of research focuses on people's attitudes toward different kinds of media. Whether they realize it or not, many people approach computers and tablets with a state of mind less conducive to learning than the one they bring to paper.
  • Both anecdotally and in published studies, people report that when trying to locate a particular piece of written information they often remember where in the text it appeared. We might recall that we passed the red farmhouse near the start of the trail before we started climbing uphill through the forest; in a similar way, we remember that we read about Mr. Darcy rebuffing Elizabeth Bennett on the bottom of the left-hand page in one of the earlier chapters.
  • ...5 more annotations...
  • At least a few studies suggest that by limiting the way people navigate texts, screens impair comprehension.
  • Because of their easy navigability, paper books and documents may be better suited to absorption in a text. "The ease with which you can find out the beginning, end and everything inbetween and the constant connection to your path, your progress in the text, might be some way of making it less taxing cognitively, so you have more free capacity for comprehension," Mangen says.
  • An e-reader always weighs the same, regardless of whether you are reading Proust's magnum opus or one of Hemingway's short stories. Some researchers have found that these discrepancies create enough "haptic dissonance" to dissuade some people from using e-readers. People expect books to look, feel and even smell a certain way; when they do not, reading sometimes becomes less enjoyable or even unpleasant. For others, the convenience of a slim portable e-reader outweighs any attachment they might have to the feel of paper books.
  • In one of his experiments 72 volunteers completed the Higher Education Entrance Examination READ test—a 30-minute, Swedish-language reading-comprehension exam consisting of multiple-choice questions about five texts averaging 1,000 words each. People who took the test on a computer scored lower and reported higher levels of stress and tiredness than people who completed it on paper.
  • Perhaps, then, any discrepancies in reading comprehension between paper and screens will shrink as people's attitudes continue to change. The star of "A Magazine Is an iPad That Does Not Work" is three-and-a-half years old today and no longer interacts with paper magazines as though they were touchscreens, her father says. Perhaps she and her peers will grow up without the subtle bias against screens that seems to lurk in the minds of older generations. In current research for Microsoft, Sellen has learned that many people do not feel much ownership of e-books because of their impermanence and intangibility: "They think of using an e-book, not owning an e-book," she says. Participants in her studies say that when they really like an electronic book, they go out and get the paper version. This reminds Sellen of people's early opinions of digital music, which she has also studied. Despite initial resistance, people love curating, organizing and sharing digital music today. Attitudes toward e-books may transition in a similar way, especially if e-readers and tablets allow more sharing and social interaction than they currently do.

Do we read differently on paper than on a screen? - 9 views

  • In total, there are more than 180 researchers from 33 different countries participating in the COST-initiated research network E-READ, reading in an age of digital transformation. This network examines the effects and consequences of digital developments in terms of reading.
  • It is not a case of "one size fits all," but patterns are beginning to emerge from empirical research into the subject. The length of the text seems to be the most critical factor. If the text is long, needs to be read carefully and perhaps involves making notes, then studies show that many people, including young people such as students, still often prefer a printed book, even if it is available as both an e-book and in electronic formats with options for making notes, enabling the user to search for and highlight the text digitally. This is not the case when it comes to shorter texts.
  • When reading long, linear, continuous texts over multiple pages that require a certain amount of concentration, referred to as "Deep Reading," the reader often experiences better concentration and a greater overview when reading from a printed medium compared to a screen. When we are reading from a screen, only one section can be seen at a time and the available reading surface area is limited. If you read a printed medium such as a book, several text areas are available simultaneously and it feels easier to form an overview and make notes in the margins.
  • ...5 more annotations...
  • However, an interesting finding in some of the empirical studies is that we tend to overestimate our own reading comprehension when we read on screen compared to on paper.
  • it has been found that we tend to read faster on screen and consequently understand less compared to when reading from paper. This is a very new research topic and there are studies that have not found any differences in this area.
  • such findings do highlight something very important, namely that we may have a different mental attitude to what we read on a screen. This has very significant implications, including in the context of education.
  • For example, reading literature has proven to have a stimulating effect on the imagination and encourage the development of empathy. Reading has an effect on our ability to concentrate and for abstract thinking. We want to discover if such processes are influenced by the reading medium.
  • There is a need for more empirical research on reading comprehension in terms of screen reading and also on the subjective reading experience.
