5 trends poised to rock education

Changing technology trends will have an near-immediate impact on teaching and learning

tech-trendFive technologies are reaching maximum impact and are about to transform education, changing just about everything, according to educational futurist Jason Ohler.

Speaking during the International Society for Technology in Education’s virtual conference on Feb. 13, Ohler noted that five trends–big data, augmented reality, the semantic web, extreme bring-your-own-device (BYOD), and transmedia storytelling–will change teaching and learning in the very near future.

    “Consider a petabyte of data, which is 1015 bytes of data…”
    ============
    This little bit of misinformation is not insignificant.

    1015 bytes of data is a about the size of a paragraph of text. Not a lot at all….

    A Petabyte (PB), however, is 1024 Terabytes (TB), or approximately 1,000,000 Gigabytes (GB). To get a sense of the magnitude of a PB see this excerpt from http://www.computerweekly.com/feature/What-does-a-petabyte-look-like:

    + If you counted all the bits in one petabyte at one bit per second, it’d take 285 million years.
    + If you counted one byte per second, it would take 35.7 million years.
    + It would take 223,000 DVDs (4.7Gb each) to hold 1Pb.
    + It would take 746 million 3.5-inch high-density floppy discs (1.44Mb each) to hold one petabyte; 746 billion floppy discs weigh 13,422 tonnes (if each one weighs 18g). This is just under the size of two Type 45 destroyers, such as the newly built HMS Duncan, which has just left the Clyde
    + Estimates of the number of cells in a human body vary, but most put the number at approaching 100 trillion, so if one bit is equivalent to a cell, then you’d get enough cells in a petabyte for 90 people – the rugby teams of the Six Nations.

      Thank you for pointing that out! I think a technical error was introduced in the posting process, and a special character did not publish. It was originally written as 10 to the 15th power. We’ll correct ASAP!
