‘Gone are the days when all that’s needed is a chalkboard and textbook to reach students. Educators who really want to have an impact are turning to technology and in many cases the results speak for themselves. A recent survey by PBS Learning Media found that 74% of teachers incorporated devices such as tablets in their lessons. The survey also found that 69% of teachers using educational technology said that it greatly enhances lessons and empowers them to teach like they’ve never been able to before.
‘But it’s not just in the classroom where the effects of technology on education can be felt. Social networks have been abuzz with interest and excitement towards these changes. Everywhere from Facebook and Twitter to blogs and forums, where hashtags like #edtech and #edchat have a firmly established following, rich communities of educators looking for innovative ways to remain relevant can be found…’
Bad DRM Again
New DRM Might ‘edit’ Your eBook from Original Print
‘The next e-book you buy might not exactly match the printed version. And those changes are there to make sure you’re not a pirate.
‘German researchers have created a new DRM feature that changes the text and punctuation of an e-book ever so slightly. Called SiDiM, which Google translates to “secure documents by individual marking,” the changes are unique to each e-book sold. These alterations serve as a digital watermark that can be used to track books that have had any other DRM layers stripped out of them before being shared online. The researchers are hoping the new DRM feature will curb digital piracy by simply making consumers paranoid that they’ll be caught if they share an e-book illicitly…’
How what you see can affect what you say
Cultural Images Affect Second Language Usage
‘Researchers performed various tests with students who had come to the U.S. from China. In one, the students heard a recorded conversation, in English, about campus life. But some looked at a Chinese face while they listened, while others saw a Caucasian face.
‘The students then spoke about their own lives. And the Chinese-American students who had listened while looking at a Chinese face spoke English more slowly and less fluently than those who listened while looking at the Caucasian face…’
Infragram Cameras: Hi-tech Gardening
‘There’s no shortage of novel Kickstarter projects that aim to change how we think about the environment, but here’s one that could literally change how we look at it. Infragram, created by the civic science-minded folks at Public Lab puts low-cost infrared cameras into people’s hands so they can better understand the health of the plants around them.
‘The goal here is simple enough — by hacking these cameras to peer into the infrared (well, near-infrared) portion of the spectrum, Public Lab hopes to let users see how well plants are converting light into oxygen. The end result is a pair of images that, when processed properly, yield a single false-color image that shows off which plants (or parts of plants) are reflecting the most near-infrared light and are therefore absorbing the most red and blue light…’
