    "A Self-Appointed Teacher Runs a One-Man 'Academy' on YouTube
    Are his 10-minute lectures the future?

    Salman Khan, a former financial analyst, has created 1,400 educational videos and posted them to YouTube. "My single biggest goal is to try to deliver things the way I wish they were delivered to me," he says.

    By Jeffrey R. Young

    The most popular educator on YouTube does not have a Ph.D. He has never taught at a college or university. And he delivers all of his lectures from a bedroom closet.

    This upstart is Salman Khan, a 33-year-old who quit his job as a financial analyst to spend more time making homemade lecture videos in his home studio. His unusual teaching materials started as a way to tutor his faraway cousins, but his lectures have grown into an online phenomenon-and a kind of protest against what he sees as a flawed educational system.

    "My single biggest goal is to try to deliver things the way I wish they were delivered to me," he told me recently.

    The resulting videos don't look or feel like typical college lectures or any of the lecture videos that traditional colleges put on their Web sites or YouTube channels. For one thing, these lectures are short-about 10 minutes each. And they're low-tech: Viewers see only the scrawls of equations or bad drawings that Mr. Khan writes on his digital sketchpad software as he narrates."

    The Rise of Crowd Science 2

    David Klammer for The Chronicle

    Hanny van Arkel, a Dutch schoolteacher, made a major astronomy discovery with a public Web site of telescope images.

    Today, data sharing in astronomy isn't just among professors. Amateurs are invited into the data sets through friendly Web interfaces, and a schoolteacher in Holland recently made a major discovery, of an unusual gas cloud that might help explain the life cycle of quasars-bright centers of distant galaxies-after spending part of her summer vacation gazing at the objects on her computer screen.

    Crowd Science, as it might be called, is taking hold in several other disciplines, such as biology, and is rising rapidly in oceanography and a range of environmental sciences. "Crowdsourcing is a natural solution to many of the problems that scientists are dealing with that involve massive amounts of data," says Haym Hirsh, director of the Division of Information and Intelligent Systems at the National Science Foundation. Findings have just grown too voluminous and complex for traditional methods, which consisted of storing numbers in spreadsheets to be read by one person, says Edward Lazowska, a computer scientist and director of the University of Washington eScience Institute. So vast data-storage warehouses, accessible to many researchers, are going up in several scholarly fields to try to keep track of the wealth of information."

    "Humans: Why They Triumphed
    How did one ape 45,000 years ago happen to turn into a planet dominator? The answer lies in an epochal collision of creativity. By Matt Ridley

    By MATT RIDLEY
    [EVOLUTION] Masterfile

    Human evolution presents a puzzle. Nothing seems to explain the sudden takeoff of the last 45,000 years-the conversion of just another rare predatory ape into a planet dominator with rapidly progressing technologies. Once "progress" started to produce new tools, different ways of life and burgeoning populations, it accelerated all over the world, culminating in agriculture, cities, literacy and all the rest. Yet all the ingredients of human success-tool making, big brains, culture, fire, even language-seem to have been in place half a million years before and nothing happened. Tools were made to the same monotonous design for hundreds of thousands of years and the ecological impact of people was minimal. Then suddenly-bang!-culture exploded, starting in Africa. Why then, why there?

    The answer lies in a new idea, borrowed from economics, known as collective intelligence: the notion that what determines the inventiveness and rate of cultural change of a population is the amount of interaction between individuals. Even as it explains very old patterns in prehistory, this idea holds out hope that the human race will prosper mightily in the years ahead-because ideas are having sex with each other as never before.

    The more scientists discover, the bigger the evolution puzzle has become. Tool-making itself

Can Learning Be Improved When the Budget Is in the Red? - Commentary - The Chronicle of... - 0 views

    "The current state of student learning in American colleges and universities leaves much to be desired. To be sure, the evidence about whether students are learning is fragmentary, imperfect, and discouraging. Most distressing are the results of the 1992 National Adult Literacy Survey and the 2003 National Assessment of Adult Literacy, which show that average literacy levels among adults with bachelor's degrees have declined over time. That's on top of the fact that the overall level is low: On average, four-year college graduates have only an "intermediate" level of literacy, meaning that they are capable of doing only "moderately challenging literacy activities." Further, data collected from the National Survey of America's College Students-which used the literacy survey-show that "20 percent of U.S. college students completing four-year degrees-and 30 percent of students earning two-year degrees-have only basic quantitative literacy skills, meaning they are unable to estimate if their car has enough gasoline to get to the next gas station or calculate the total cost of ordering office supplies.""

    "The transition within the book publishing industry from physical inventory stored in a warehouse and trucked to retailers to digital files stored in cyberspace and delivered almost anywhere on earth as quickly and cheaply as e-mail is now underway and irreversible. This historic shift will radically transform worldwide book publishing, the cultures it affects and on which it depends. Meanwhile, for quite different reasons, the genteel book business that I joined more than a half-century ago is already on edge, suffering from a gambler's unbreakable addiction to risky, seasonal best sellers, many of which don't recoup their costs, and the simultaneous deterioration of backlist, the vital annuity on which book publishers had in better days relied for year-to-year stability through bad times and good. The crisis of confidence reflects these intersecting shocks, an overspecialized marketplace dominated by high-risk ephemera and a technological shift orders of magnitude greater than the momentous evolution from monkish scriptoria to movable type launched in Gutenberg's German city of Mainz six centuries ago."

Transforming Course Design - 3 views

    "Transforming Course Design is a process to improve student learning while simultaneously addressing the issue of instructional costs. Faculty from a variety of disciplines and institutions describe the steps they took to redesign their course structures to meet these goals, and the impact on their students and on their own perspectives on instruction.

From the Campus to the Future (EDUCAUSE Review) | EDUCAUSE - 1 views

    "To address these changes, the Council of Australian University Directors of Information Technology (CAUDIT, http://www.caudit.edu.au/), the U.S.-based EDUCAUSE (http://www.educause.edu/), the United Kingdom's Joint Information Systems Committee (JISC, http://www.jisc.ac.uk/), and the Netherlands' SURFfoundation (http://www.surffoundation.nl/en/) undertook a collaborative visioning of the future of higher education. Although information technology is the focus of all four of these associations, the resulting white paper (from which this article is drawn) explores higher education overall, not just information technology.2 The value of information technology lies in the activities it supports, which span virtually every college and university system for managing finances, learning, research, security, sustainability, and more. IT professionals thus need to understand the larger issues faced by their institutions: the drivers of change and the enablers, themes, and questions for the future."
