AT&T dismissed the idea that providers would redline
,
-------------------------------------------------------------

I first noticed this in the 1980s when I discovered that
groceries in the suburbs were way better than the ones in
the inner city where I lived. And now it's an internet is a
problem I'm living with right now. I live in Casselman, a
small town in rural Ontario, and even though fibre-optic
internet cable passes right through town we cannot obtain
high-speed internet. The phenomenon is known as 'redlining
Link.
According to Wikipedia
Linkit's "the practice
of denying services, either directly or through selectively
raising prices, to residents of certain areas based on the
racial or ethnic composition of those areas." Wikipedia's
definition is too narrow, of course. "The data... show a
clear and troubling pattern: A pattern of long-term,
systematic failure to invest in the infrastructure required
to provide equitable, mainstream Internet access to
residents of the central city (compared to the suburbs) and
to lower-income city neighborhoods." This article notes
"AT&T dismissed the idea that providers would redline
or cherrypick communities, and legislators apparently
believed them." Of course, that's exactly what happens - in
the U.S., in Canada, and around the world.

Who lost the most marks when cheating was stopped?

I found this to be an interesting result. After cheating in
Romanian exams was curtailed, "the pass rates of poorer
students - those in receipt of financial assistance
payments - fell by 14.3%, compared to 8.1% for better-off
students." Now it might be tempting to say that the
anti-cheating policy was anti-poor. But that would be
simply to blame the messenger. "When corruption was
widespread, we couldn't know the true scale of
inequality… Our findings have revealed just how much
greater the equality gap is. Once we know the true gap in
attainment, the government can tackle the source of the
inequality."

Microlearning: What It Is Not and What It Should Be
,
-------------------------------------------------------------
Link
'Microlearning' is one of those terms that is becoming
increasingly vague with use and popularity. According to
this article, "the term 'microlearning' was coined by the
Research Studios Austria as "learning in small steps," and
it has been heavily popularized due to most of its
interventions being Web 2.0 friendly." It is not itself a
theory but can be associated with cognitive load theory
(CLT). According to t he article, "CLT was first described
by John Sweller, and it proposes that 'learning occurs in
two mechanisms: 1) schema acquisition, or forming a mental
map, and 2) transfer of knowledge into working
memory.'” The idea is derived from George A.
Miller's work Linkin the
1950s (setting our cognitive capacity at 7 items, plus or
minus 2). Microlearning, says the article, "is not a
one-size-fits-all approach, but rather a good companion for
formal instruction. Microlearning may not be an optimal
solution for complex tasks in workplace learning."

Every day I'm online, it seems, there's a whole new
technology to learn. Yesterday I was messing around with
Bower Linkwhich has been around a
while but which I hadn't time to learn previously. Today
it's on to WebVR. This article looks at Mozilla's A-Frame
Linka web framework for building virtual
reality experiences. A-Frame is based on HTML and the
Entity-Component pattern
https://aframe.io/docs/0.5.0/introduction/#entity-component-system."
There's a demo based on "a basic VR voxel builder." Think
Minecraft. "The voxel builder will be primarily for room
scale VR with positional tracking and tracked controllers
(e.g., HTC Vive, Oculus Rift + Touch)." It also works on
desktop and mobile - see the demonstration here
Linkand play with it
yourself by downloading code from GitHub

The open in MOOC must include the ability to create courses
,
-------------------------------------------------------------
Link
"If we want truly open education," writes Graham Attwell,
"then we need to open up opportunities for creating and
facilitating learning as well as participating in a
programme." I agree. He also adds
Link"Brian Mulligan
responded... with a link to the Moocs4All web site
Linkthe web site includes this promo
video for a free course held last year on ‘Making
MOOCs on a budget.'" But as he notes, "it is possible to
hack a MOOC platform together with WordPress or to install
Open edX https://open.edx.org/" target="_blank. But it
isn’t simple." All true.
But. As readers know, my gRSShopper
Linksoftware has always been open
source. This is what was used to launch the first MOOCs and
what I still use to manage my newsletter. Like the other
hacks, however, it is difficult to install. But this will
soon change. I am almost completed work on gRSShopper in a
box. This will be a fully contained gRSShopper server
you can easily run anywhere. You will be able to use it as
either a MOOC or as a PLE (and of course you can use your
PLE to take MOOCs). It's not an official project so it has
been slow going, but it won't be long now. Stay tuned.
