College Board Standards for College Success - 0 views

  •  
    About the College Board Standards for College Success (CBSCS) The College Board Standards for College Success (CBSCS) define the knowledge and skills students need to develop and master in English language arts, mathematics and statistics, and science in order to be college and career ready. The CBSCS outline a clear and coherent pathway to Advanced Placement® (AP®) and college readiness with the goal of increasing the number and diversity of students who are prepared not only to enroll in college, but to succeed in college and 21st-century careers. The College Board has published these standards freely to provide a national model of rigorous academic content standards that states, districts, schools and teachers may use to vertically align curriculum, instruction, assessment and professional development to AP and college readiness. These rigorous standards: provide a model set of comprehensive standards for middle school and high school courses that lead to college and workplace readiness; reflect 21st-century skills such as problem solving, critical and creative thinking, collaboration, and media and technological literacy; articulate clear standards and objectives with supporting, in-depth performance expectations to guide instruction and curriculum development; provide teachers, districts and states with tools for increasing the rigor and alignment of courses across grades 6-12 to college and workplace readiness; and assist teachers in designing lessons and classroom assessments.

Experts Agree Global Warming Is Melting the World Rapidly - 0 views

    Experts Agree Global Warming Is Melting the World Rapidly Richard A. Kerr Forty-seven glaciologists have arrived at a community consensus over all the data on what the past century's warming has done to the great ice sheets: a current annual loss of 344 billion tons of glacial ice, accounting for 20% of current sea level rise. Greenland's share-about 263 billion tons-is roughly what most researchers expected, but Antarctica's represents the first agreement on a rate that had ranged from a far larger loss to an actual gain. The new analysis, published on page 1183 of this week's issue of Science, also makes it clear that losses from Greenland and West Antarctica have been accelerating, showing that some ice sheets are disconcertingly sensitive to warming.

Pelagic Fishing at 42,000 Years Before the Present and the Maritime Skills of Modern Hu... - 0 views

  •  
    abstract By 50,000 years ago, it is clear that modern humans were capable of long-distance sea travel as they colonized Australia. However, evidence for advanced maritime skills, and for fishing in particular, is rare before the terminal Pleistocene/early Holocene. Here we report remains of a variety of pelagic and other fish species dating to 42,000 years before the present from Jerimalai shelter in East Timor, as well as the earliest definite evidence for fishhook manufacture in the world. Capturing pelagic fish such as tuna requires high levels of planning and complex maritime technology. The evidence implies that the inhabitants were fishing in the deep sea.

Galaxy Zoo Volunteers Share Pain and Glory of Research - 0 views

    Science 8 July 2011: Vol. 333 no. 6039 pp. 173-175 Galaxy Zoo Volunteers Share Pain and Glory of Research 1. Daniel Clery A project to "crowdsource" galactic classifications has paid off in ways the astronomers who started it never expected.

KEEL (UNIVERSITY OF ALABAMA), AND THE GALAXY ZOO TEAM" The automated surveys that are becoming increasingly common in astronomy are producing an embarrassment of riches for researchers. Projects such as the Sloan Digital Sky Survey (SDSS) are generating so much data that, in some cases, astronomers don't know what to do with them all. SDSS has compiled a list of more than 1 million galaxies. To glean information about galaxy evolution, however, astronomers need to know what type of galaxy each one is: spiral, barred spiral, elliptical, or something else. At present, the only reliable way to classify galaxies is to look at each one. But the SDSS list is so long that all the world's astronomers working together couldn't muster enough eyeballs for the task. Enter the "wisdom of crowds." An online effort called Galaxy Zoo, launched in 2007, set a standard for citizen-scientist participation projects. Zealous volunteers astonished the project's organizers by classifying the entire catalog years ahead of schedule. The results have brought real statistical rigor to a field used to samples too small to support firm conclusions. But that's not all. Buoyed by the curiosity and dedication of the volunteers, the Galaxy Zoo team went on to ask more-complicated classification questions that led to studies they hadn't thought possible. And in an online discussion forum on the Galaxy Zoo Web site, volunteers have pointed to anomalies that on closer inspection have turned out to be genuinely new astronomical objects.
