Group talk uncovered (Greg Horton)

Brad Patterson, from Edulang, is introducing their new initiative for ESL teachers and learners.

Language in humans has evolved culturally rather than genetically, according to a study by UCL (University College London) and US researchers. By modelling the ways in which genes for language might have evolved alongside language itself, the study showed that genetic adaptation to language would be highly unlikely, as cultural conventions change much more rapidly than genes. Thus, the biological machinery upon which human language is built appears to predate the emergence of language. According to a phenomenon known as the Baldwin effect, characteristics that are learned or developed over a lifespan may become gradually encoded in the genome over many generations, because organisms with a stronger predisposition to acquire a trait have a selective advantage. Over generations, the amount of environmental exposure required to develop the trait decreases, and eventually no environmental exposure may be needed - the trait is genetically encoded. An example of the Baldwin effect is the development of calluses on the keels and sterna of ostriches. The calluses may initially have developed in response to abrasion where the keel and sterna touch the ground during sitting. Natural selection then favored individuals that could develop calluses more rapidly, until callus development became triggered within the embryo and could occur without environmental stimulation. The PNAS paper explored circumstances under which a similar evolutionary mechanism could genetically assimilate properties of language - a theory that has been widely favoured by those arguing for the existence of 'language genes'. The study modelled ways in which genes encoding language-specific properties could have coevolved with language itself. The key finding was that genes for language could have coevolved only in a highly stable linguistic environment; a rapidly changing linguistic environment would not provide a stable target for natural selection. Thus, a biological endowment could not coevolve with p

NPR, Harris Corporation and Towson University today announced a new initiative to make radio more accessible to the hundreds of millions of hearing and visually impaired people around the world.

A reaction essay is an essay that is written in response to something else. The initial topic that the writer is responding to could be anything from a speech that was heard to another essay to the latest breaking news event.

"Introduction In recent years, the world has witnessed a growing wave of local initiatives in support of public schools. Teachers, cultural associations and civil society have been playing an active part in grassroots experiments aimed at helping schools in the creative elaboration of new educational methods, also exploiting information technologies. Here answers are coming from those directly faced with educational issues, in contrast with the more common top-down reforms, where experts' committees draw up didactic experimentation plans to be put forward to willing teachers. Experiments like that are often very effective but, unfortunately, they rarely get known beyond the immediate sphere of their promoters. Moreover, they tend to be short-lived because promoters don't have the strength to sustain them and a suitable supporting network is lacking. They are like drops in the ocean: they apparently cannot change the entire educational system. But the ocean of whole human community could be flooded by many such contained experiments that would transform it, if the most meaningful of them could be fostered, spread and developed. ..."

Today, we're launching an initiative to help authors and publishers discover new audiences for books they've made available for free under Creative Commons (CC) licenses. Rightsholders who want to distribute their CC-licensed books more widely can choose to allow readers around the world to download, use, and share their work via Google Books.

participation as the key to the successful development of web2.0 initiatives

In most if not all 1:1 student laptop initiatives, "instant messaging" is a hot topic for both students and teachers. Typically and predictably, students want access to instant messaging, while many teachers and administrators see IM as a distraction comparable to video games. Both IM and video games are often regarded as "problems" for the classroom teaching and learning environment, rather than powerful tools that can be leveraged for transformative educational experiences.
