Questions That Frame Responsibility
Full Circle, January 17, 2012.
Nancy White writes, "I have been intrigued by questions that help frame responsibility in a group, rather setting up an expectation that the convenors, facilitators, leaders, whatever — are responsible for everything." My thinking is that this is half-correct. Yes, we have to stop depending on the leaders - from President to Shop Floor Supervisor - to do it all. On the other hand, this responsibility does not shift into that formless entity called 'the group' because the group is congenitally incapable of assuming it. Rather, each individual within the group assumes an partial and interconnected responsibility. That's a very different picture.

What is big data?
O'reilly Radar, January 17, 2012.
A nice definition: "Big data is data that exceeds the processing capacity of conventional database systems. The data is too big, moves too fast, or doesn't fit the strictures of your database architectures. To gain value from this data, you must choose an alternative way to process it." The location of all the traffic in a large city, for example, would be an instance of Big Data. So how do we work with it? "Today's commodity hardware, cloud architectures and open source software bring big data processing into the reach of the less well-resourced." What does that mean for education? I think most of all it forces us to reassess sentences like "the fact is..." because the 'fact', whatever it is, is big, messy, and will be different tomorrow. That doesn't mean there's no fact - it does mean, though, that the fact does not fit neatly into slogans, management principles or textbooks.

Notes: O’Donnell (2006): Blogging as pedagogic practice: Artefact and ecology
D'Arcy Norman dot net, January 17, 2012.
D'Arcy Norman blogs a summary of Marcus O'Donnell's paper Blogging as pedagogic practice: Artefact and ecology. He's been doing a number of these paper summaries recently. O'Donnell "talks about some of the promise of blogging as an agent of pedagogical change, but actually goes into some of the reasons why the change might happen." So what are these reasons? "A blog... operates at the core of a personal network or set of personal relationships.... the author can learn to work with a blog as an evolving hypertext essay by thoughtfully linking backwards and forwards to their own as well as others' posts [so] an ecological practice, which reveals emergent knowledges as a series of dynamically linked spaces." (That's a bit of an interpretation but I think it expresses the right idea.)

Network: The Secret Life of Your Personal Data, Animated
Brain Pickings, January 17, 2012.
I just connected my Blogger account to my Google+ account (Google had been maintaining the polite fiction that they were separate). I also validated my ownership of downes.ca for Google+ (done in pretty much the same way Technorati did it way back when, or even my home grown ID system did). As Ben Werdmuller says, identity is the operating system. So this visualization of your personal data making its way through the network is especially poignant today. "The average user has 736 pieces of this personal data collected every day, and different service providers retain this information for anywhere between 12 and 60 months." Yeah, look at that data go! Related: Manuel Lima talks on the power of networks at the RSA.

Apple to announce tools, platform to "digitally destroy" textbook publishing
Ars Technica, January 17, 2012.
There have been hints aplenty laid down about Apple's forthcoming announcement with the suggestion that it will impact online learning directly. If it's as suggested in this article - "Apple will announce tools to help create interactive e-books - the 'GarageBand for e-books,'" - then there may be something to it. Me, I've had a 'GarageBand for eBooks' for years - it's called my word processor or text editor, and I've been using it to distribute interactive multimedia content on the web for years. But maybe what I really needed was a proprietary interface and the Apple brand. And maybe a file format that won't play on the open web? Ah - but maybe I'm too cynical. Prepare to read the gushing reviews Thursday. More Here. And here.

Kirkpatrick's Revised Four Level Evaluation Model `
Plan B, January 17, 2012.
Interesting reworking of Kirkpatrick's four levels of evaluation of workplace learning:
- motivation - do they want to learn and perform?
- learning - did they learn the skills and/or use the resources they were given?
- performance - did they transfer their skills to the workplace?
- results - is the desired impact being felt?
And you could still add the sometimes-mentioned fifth level: is there a return on investment or impact on the bottom line?

ED218 Developing mathematics: The early years
P2PU, January 17, 2012.
Maria Droujkova writes in Facebook, "I am leading a MOOC (massive open online course) this Spring. The sign-up is open January 17-22 at P2PU School of Math Future. The course, "Developing mathematics: The early years" is offered for credit to Arcadia University students, and for School of Math Future completion certificate to everybody. It has the following overarching themes:
- Personally meaningful and relevant mathematics achieved through projects, games, problem-posing and problem-solving.
- Computer-based mathematics, including interactive simulations, modeling tools, solvers, and children programming platforms.
- Lifelong learning for teachers, with the focus of online communities and networks for teacher support, and building your personal learning networks

Objectivity and impartiality: newsroom policy
Online Journalism Blog, January 17, 2012.
There's a bit of a debate in the online news world that I think is long overdue: whether reporters should 'fact check' their sources. As the proposed wording states: "If someone misrepresents the facts, do not simply say someone else disagrees, make a statement along the lines of 'However, the actual wording of the report…' or 'The official statistics do not support her argument' or 'Research into X contradict this.' And of course, link to that evidence and keep a copy for yourself (which is where transparency comes in)." But of course this is controversial, with critics suggesting that this amounts to telling reporters to be "truth vigilantes." But as Matthew Ingram says, "media outlets that leave this kind of function to third parties risk losing the trust of their readers." Where do I stand on this? On the side of the truth. Where else? People in positions of trust - doctors, lawyers, journalists, teachers, scientists - have an obligation to correct errors of fact.

Wikipedia, January 16, 2012.
Wikipedia will be among those joining in a web-wide blackout to protest againt the American SOPA legislation that threatens to block DNS lookups against sites accused of piracy. If you want to join the blackout, there is a simple blackout script that you can add to the top of your page. See also this article. Reddit will also be joining, as well as some others. Anonymous is joining. There are some reports that Craigslist and Minecraft will join. Still waiting to see whether Google and Facebook will follow. Mashable says Google will. Twitter, quite apparently, will not. But tens of thousands of their members will. Adam Curry, meanwhile, makes some good counterarguments to the SOPA protest. But Michael Geist makes good arguments of his own explaining why Canadians should black out their sites for the protest.
