Malawi app 'teaches UK pupils 18 months of maths in six weeks'

By Stephen Downes - Stephen's Web. Malawi app 'teaches UK pupils 18 months of maths in six weeks'
Spencer Kelly, BBC News, 2014/09/08

There's all kinds of ways this can be an overstatement and that the results in widespread practice would be nowhere near the test case (or not long-lasting, nor not transferable, or some such thing). More...

Twitpic is shutting down

By Stephen Downes - Stephen's Web. Twitpic is shutting down
Press Release, TwitPic, 2014/09/08
I don't know whether Twitpic is actually shutting down or whether this is just posturing to get Twitter to pack down, but either way it demonstrates how we can't depend on web service providers to have our interests in mind when they begin fighting (as they always do) among themselves. More...

Bonnie Stewart, The theoryblog, 2014/09/08
"Will my dissertation end up being about the Twitter that was, rather than whatever it is in the process of becoming?" Bonnie Stewart looks at the decline of Twitter not just as an isolated event but as part of a wider pattern. More...

Twitter, algorithms, and digital dystopias

Doug Belshaw, 2014/09/08
So what happened after people exchanged their RSS readers for services like Twitter and Facebook? "What’s so problematic about all of this, of course, is that whereas we used to be in charge of our own reading habits, we’ve outsourced that to algorithms. More...

By Stephen Downes - Stephen's Web. The Launch of Twitter’s Analytics Service
Brian Kelly, UK Web Focus, 2014/09/08
Twitter has launched a new analytics service. Here's the announcement. Brian Kelly: "the service provides statistics on tweets (potential impressions, engagement and engagement rate). Additional tabs provide information on followers (changes in the numbers of followers and profiles of their gender, location and interests) and Twitter cards." I'm not sure I even want this. More...

Mute the Messenger

By Stephen Downes - Stephen's Web. Mute the Messenger
Jason Stanford, Texas Observer, 2014/09/10
Walter Stroup offered evidence to show that standardized tests measure test-taking ability more than they measure knowledge, and that the teacher has only a small impact on the final assessment. "According to Stroup’s initial calculations, that constancy accounted for about 72 percent of everyone’s test score." A later recalculation suggests it's more like 50%. More...

Ben Werdmuller, Benwerd, 2014/09/10

It's what I think my Referrer System, which I built in 2002, would have become had it grown up (it peaked at 800K hits per day, and I didn't have the resources to sustain that).

In this good summary of the results of the recent study comparing note-taking with pen and laptop Darren Kuropatwa also points to the underlying reason to be sceptical about the conclusion.

Responsive design, JQuery libraries, Bootstrap, HTML templates, CSS preprocessors... the world of web page design has become impressively complex.
