Education Focus
  • Shopping lists and other cognitive tools | Webs of Substance 'Standard algorithms are the mathematical equivalent of phonics. Unless statutes require them to be taught then there are ideologues who will willfully neglect them. [...] Of course, there are occasions when standard algorithms are not appropriate or efficient (80 plus 12 or when completing mental maths) but, for any given problem, there will always be a most efficient strategy. And for most pencil-and-paper operations involving two-digit numbers or more, the standard algorithms are the best.' OK, as long as you understand the principles well enough to know whether ot not the answer is plausible.

  • A Tablet for Africa? | AfriGadget  'The Betabook is a portable whiteboard, which can be used with a smartphone for archiving, content creation, and social media sharing.'
  • Christmas Gift! - The American Interest 'What makes this holiday so irresistible and global, yet also so particular and controversial? Why do so many people love Christmas while rejecting or in some cases actively hating Christianity? And why do so many others hate Christianity so deeply that they want to suppress all public celebration, however secular, of the symbols of Christmas? [...] For that matter, why do so many followers of the man who famously blessed the poor celebrate his birthday with the greatest spending sprees the world has ever known? How did the birthday of a crucified religious teacher become an excuse to drink egg nog?'
