"R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R. R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity."

"A fine example of this emerged in January of this year, with release of a study by University of Western Ontario neuroscientist Daniel Ansari and Harvard's Aaron Berkowitz, who studies music cognition. They put Dartmouth music majors and nonmusicians in an fMRI scanner, giving participants a one-handed fiber-optic keyboard to play melodies on. Sometimes melodies were rehearsed; other times they were creatively improvised. During improvisation, the highly trained music majors used their brains in a way the nonmusicians could not: they deactivated their right-temporoparietal junction. Normally, the r-TPJ reads incoming stimuli, sorting the stream for relevance. By turning that off, the musicians blocked out all distraction. They hit an extra gear of concentration, allowing them to work with the notes and create music spontaneously."

Science, math and technology simulations that work great in the computer lab or on your interactive whiteboard.

Here's the second of the Will R posts that are linked to the Diane Ravitch post.

In light of the interesting back and forth that occurred on my last post, I've been thinking about what the fundamental lessons of schooling ought to be and the role of technology in helping us teach them.

Ning network to communicate about the dangers of texting while driving.

a MUST SEE!

Seriously. If you're a Facebook user you need to check this out. Yes, it's eye candy, but VERY cool!

Probably worth 5 mins of you time. Wow!

Wow! Would you like to feel grounded? give 5min to this this video and you won't be sorry.

Before you click on that tinyurl that someone just tweeted to you, you might want to check it out here first. If it doesn't show up - DO NOT CLICK IT!

"Swiffy converts Flash SWF files to HTML5, allowing you to reuse Flash content on devices without a Flash player (such as iPhones and iPads). Swiffy currently supports a subset of SWF 8 and ActionScript 2.0, and the output works in all Webkit browsers such as Chrome and Mobile Safari. If possible, exporting your Flash animation as a SWF 5 file might give better results. "
