A new site hopes the seemingly simple idea of eliminating the language barrier, letting you write in English and be read in Arabic — and vice versa — will cultivate citizen diplomacy between the Middle East and the West. It aims to reduce tensions at the grassroots level between two cultures that increasingly co-exist but seem a world apart.

People who don’t share a common language can have an online discussion in near real time. The name, appropriately, means “gathering place” or “town hall” in Arabic.

Think of it as a social network filled with people you don’t know, but want to understand.

How can we take high tech tools and make them work in low tech classrooms?

Students in my kids’ class are learning the alphabet. After learning each set of

etters, they enjoy making “human” letters.

For example, when babies born to native-English-speaking parents played three times a week during that window with a native-Mandarin-speaking tutor, at 12 months, they had progressed in their ability to recognize both English and Mandarin sounds, rather than starting to retrench in the non-native language. By contrast, children exposed only to audio or video recordings of native speakers showed no change in their language trajectory. Brain-imaging of the same children backed up the results of test-based measures of language specialization.

The research may not immediately translate into a new language arts curriculum, but it has already deepened the evidence for something most educators believe instinctively: Social engagement, particularly with speakers of multiple languages, is critical to language learning.

“The key to that series of studies is exposure and live interactions with native speakers,” Ms. Lebedeva said. “The interactions need to be naturalistic: eye contact, gestures, exaggerated phonemes.”

Grand narratives – such as provide us with a large umbrella that we can use to make sense of the world – have been besieged over the last several decades. Grand narratives in the form of newspapers, newscasts, and books are now augmented by blogs and YouTube videos.

an attempt to provide or create some type of a narrative – namely, a narrative of coherence.

In a traditional course, the educator hacks the trails to complex information landscapes. The educator’s bias influences what is included and excluded.

ELA: There are more sobering notes among the n-grams. For instance, here's the trajectory of Marc Chagall, an artist born in 1887. And this looks like the normal trajectory of a famous person. He gets more and more and more famous, except if you look in German. If you look in German, you see something completely bizarre, something you pretty much never see, which is he becomes extremely famous and then all of a sudden plummets, going through a nadir between 1933 and 1945, before rebounding afterward. And of course, what we're seeing is the fact Marc Chagall was a Jewish artist in Nazi Germany. Now these signals are actually so strong that we don't need to know that someone was censored. We can actually figure it out using really basic signal processing. Here's a simple way to do it. Well, a reasonable expectation is that somebody's fame in a given period of time should be roughly the average of their fame before and their fame after. So that's sort of what we expect. And we compare that to the fame that we observe. And we just divide one by the other to produce something we call a suppression index. If the suppression index is very, very, very small, then you very well might be being suppressed. If it's very large, maybe you're benefiting from propaganda.

Now when Google digitizes a book, they put it into a really nice format. Now we've got the data, plus we have metadata. We have information about things like where was it published, who was the author, when was it published. And what we do is go through all of those records and exclude everything that's not the highest quality data. What we're left with is a collection of five million books, 500 billion words, a string of characters a thousand times longer than the human genome -- a text which, when written out, would stretch from here to the Moon and back 10 times over -- a veritable shard of our cultural genome.
