By Stephen Downes - Stephen's Web. Active players in a network tell the story: Parsimony in modeling huge networks

One problem with studying networks is the huge amount of data generated. But what if you just studied the active members of a network, thus reducing significanty the data that hs to be crunched? Would it be reliable? In some cases, yes. More...

From Open To Connected

Gardner Campbell, Gardner Writes, Aug 10, 2014
One of the points I've tried to make over the years is that open learning requires commented learning, and vice versa. That's why the drive to trivialize the 'open' in MOOC isn't just an accessibility problem, it's a pedagogical problem. Campbell writes, "we may well have missed the greater and more important aims that “open” strives toward. More...

Personalization and the 2 Sigma Problem

By Stephen Downes - Stephen's Web. Personalization and the 2 Sigma Problem
Arthur VanderVeen, EdSurge, Aug 10, 2014

There was once this think called 'programmed learning' which was essentially designed as a series of branches and options (like a computer program). Originally pioneered by B.F. Skinner, it was all the rage for a while, but has virtually disappeared. Easly computer games followed the same design - I still remember seeing a 'laser disk' game that was again a set of options and branche. More...

Les grandes villes résistent mieux à la crise de l’emploi que le reste du territoire

http://emploiparlonsnet.fr/sites/all/themes/pole_emploi/images/head2.jpgPar Jean-Pierre Gonguet. Depuis la crise financière de 2008, la France métropolitaine a résisté de manière très inégale à la montée du chômage. Marianne Borzic et Thomas Le Jeannic de l’INSEE ont cartographié l’évolution de l’emploi. Première conclusion : les marchés du travail des métropoles ont beaucoup mieux résisté que le reste du territoire. La raison ? Ils sont en général peu orientés vers l’industrie et leur spécialisation dans le tertiaire (où le choc de la crise a été de plus faible ampleur) les a relativement préservés.
L’INSEE met ainsi en évidence un phénomène de fond. D’abord les 14 plus grandes aires urbaines, plus de 210 000 emplois en 2011, captent l’essentiel de la croissance de la population active de 25 à 54 anse.
