"Toss your PowerPoint presentations. It's (sic) text-based (nearly 40 words
per slide), with six hierarchical levels of chapters and subheads — all
words. Professionals everywhere need to know about the incredible
inefficiency of text-based information and the incredible effects of
images. Burn your current PowerPoint presentations and make new ones."

I enjoyed John Medina's excellently implemented, thoroughly referenced, browsable and entertaining Brain Rules: 12 Principles for Surviving and Thriving at Work, Home, and School partly because it complemented some of my prejudices.
I did my teacher-training in 1976-1977, and the proportion of the
1-year full time course devoted to the science of learning was small.
(Sure, 30 years ago less was known about the subject than is the
case now.)
Medina's web site could not have been produced in 1976 (either technically, or from the point of view of its science), but one would hope that teachers and others will be making a point of using it now, whilst retaining plenty of the natural scepticism we evolved for life as hunter gatherers. (One of Medina's points is that our brains and bodies evolved to make us fitted for life as hunter gatherers, and his 12 "rules" are built on that assumption.) One thing Medina's slick web site would benefit from, though it would be costly to manage, is some space for (peer reviewed) challenges to the science that underpins his "rules". For a 2 March 2009 overview of Medina's site see this post by Donald Clark.

Mobilising the minds of the masses - Anil Ananthaswamy in the New Scientist

"The total amount of idle time literate, English speaking mobile phone subscribers have within the developing world is estimated to be more than 250,000,000 hours every day. Given high rates of unemployment and marginal income sources, much of this population would greatly benefit from even an extra dollar per day."
Interesting article in the 14 February 2009 New Scientist by Anil Ananthaswamy. The article is partly about Nathan Eagle's txteagle, a service that "allows rural Kenyans to earn airtime and money by performing small tasks such as translation and transcription using their mobile phones" (from whose site the above excerpt is taken), but it develops into a more general discussion about mobile phones, and the credit they hold, as payment-transaction devices in less developed countries, using Safaricom (a mobile-phone based banking system) as an example.
Nathan Eagle is a research scientist at MIT and his Nokia-funded work on "reality mining" is also of interest.
