Better Residential Learning Is The True Innovation of MOOCs
I’d argue, however, that the true innovations of MOOCs are not those found inside the open online courses. The most important innovations catalyzed by MOOCs have very little to do with technology, or even pedagogy. Rather, they are innovations at the level of institutional organizational and cultural change. Happily, these organizational and cultural changes all result in more attention and investment in residential learning.

Colleges explain why they 'double-dipped' with MOOCs | Inside Higher Ed
Many colleges have “double-dipped” by joining both Coursera and edX, two major MOOC providers, since MOOCs went mainstream in 2012. For example, the California Institute of Technology, Rice University and the University of Toronto all partnered with Coursera in July 2012 and then joined edX in 2013. Similarly, Peking University in Beijing first partnered with edX in May 2013, then with Coursera three months later.
But among colleges and universities in the U.S., movement from one MOOC platform to the next is a one-way street. According to an Inside Higher Ed analysis, at least 10 of the institutions that first partnered with Coursera have since joined edX. Not a single edX institution has gone the other way.
After adding the University of Michigan to its list of charter members last week, edX has now recruited all of Coursera’s earliest partners, including the University of Pennsylvania, which joined in June, and Princeton University, in September. Even Stanford University, where Coursera co-founders Daphne Koller and Andrew Ng are faculty members, has since 2013 been a major contributor to Open edX, the MOOC provider’s open-source platform.
Joining a MOOC platform means doing more than filling out a sign-up sheet. Some universities have invested millions in order to become members, while individual MOOCs can cost hundreds of thousands of dollars to develop.

At Uber, the Algorithm Is More Controlling Than the Real Boss - Digits - WSJ
The researchers, who conducted in-depth interviews with Uber drivers and studied posts in drivers-only online forums, situate Uber and similar sharing-economy platforms in a wider conversation about the trend toward employee management and so-called on demand or predictive scheduling software. Starbucks SBUX -0.43%, for instance, hasn’t replaced traditional managers, but it’s among a growing group of companies that increasingly rely on software to manage worker schedules and behavior.

Bottom line: Robots aren’t stealing your job – at least in this instance – but they’re becoming your boss. And the level of control and surveillance they exert is often far greater than human management would, the authors found.

Rather than undertaking a human-driven performance review process, Uber evaluates employees according to an automated rating system. Riders enter scores into the Uber app to rate drivers with one to five stars. Back-end software tallies the scores and sends drivers regular summaries of their performance and how they stack up to their peers.

The system, the researchers wrote, empowers Uber customers to serve as “middle managers,” essentially outsourcing management. It lets Uber “achieve an organization where the workforce behaves relatively homogeneously” without needing a manager to bark orders.

Release 2015-11-04 Ops Note - Google Groups
Fixing cohorts


As a part of today's release, we've released a data migration intended to fix a potential issue with cohorts. If you don't use cohorts, you can stop reading now. Also, if you are using a named release like Cypress or Birch, then you can stop reading now.  These instructions are for sites following master closely.

The bug we fixed was a potential for users to be enrolled in multiple cohorts simultaneously, due to a race condition. As a part of this fix, we've included a data migration in the course_groups django application.

However, that isn't quite enough. As illustrated by this gist (https://gist.github.com/efischer19/d62f8ee42b7fbfbc6c9a), it's possible for databases to get out of sync during rollout of this migration and the subsequent code changes. To remedy this, we've also included a django management command, post_cohort_membership_fix, that should be run after the migrations and code rollout have been finished. At that point, you'll be fully up-to-date and have "only 1 cohort per-user per-course" protection turned on going forward.

The command we ran, in full, was:
$ sudo -u www-data -E /edx/bin/python.edxapp /edx/app/edxapp/edx-platform/manage.py lms --settings aws post_cohort_membership_fix commit

Your sudo user and --settings values may be different. Note that running this command without the additional "commit" parameter will execute in dry-run mode, and show you what would be changed without actually impacting any data.

If you're interested, the code for this command is located at https://github.com/edx/edx-platform/blob/master/openedx/core/djangoapps/course_groups/management/commands/post_cohort_membership_fix.py

A look inside edX's learning laboratory (essay) | Inside Higher Ed
Interview with Agarwal Anant that contains his particle accelerator comment. From 2013.

"Funded with $60 million in seed capital from MIT and Harvard, edX can make a claim to being the first MOOC platform to market, inasmuch as its predecessor, MITx, was launched in December 2011. Until this week,  the edX consortium featured five independent member institutions (MIT, Harvard, the University of California at Berkeley, Georgetown University, and Wellesley College) and one state university system comprising 15 colleges and universities (the University of Texas System). Thursday, it added six more, including several outside the United States.

Uber's Phantom Cabs | Motherboard
More on Uber's algorithm, surge pricing, etc.

“From a purely engineering problem, trying to fit a lot of fairly complex information fairly intuitively into an iPhone screen [is] without a doubt one of our biggest issues,” said Uber data scientist Kevin Novak in a 2014 presentation [relevant part starts at 38:30] to a meetup group.

In theory, if Uber displayed the real-time positions of drivers, that information could be used by competing driver services, who might send their drivers to fill any gaps. But another Uber Help staff who advised Heather on the phantom car issue added, “The Uber Engineers are working hard in trying to improve the software for us to be able to have a real-time view of the availability of Uber partners in the area.”

Yet, by keeping the app’s users in the dark about the accuracy or the limitations of the information it relays currently, Uber may be able to leverage more control over how drivers and passengers interact with the system.

Uber’s algorithm and the mirage of the marketplace.
Authors claim Uber is not a marketplace becuase it uses predicted demand rather than actual demand. And also because it uses a phantom image to keep consumers - it shows cars around when they may not actually be there.

Thrun Enters Burgeoning Sieve Market | Hapgood
Interesting that one of the clsases discussed is meant to attract developers to the Google platform - so this has become another purpose of MOOCs

If Wilson seems slightly unprofessional as an educator, that’s because his only formal teaching credential is as an assistant scuba-diving instructor. Wilson works at Google as a developer advocate in the company’s Chrome division. His class was conceived, and paid for, by Google as a way to attract developers to its platforms. Over the past year, Udacity has recruited a dozen or so companies, including Autodesk, Intuit, Cloudera, Nvidia, 23andMe, and Salesforce.com, which had sent a couple of reps to discuss a forthcoming course on how to best use its application programming interface, or API. The companies pay to produce the classes and pledge to accept the certificates awarded by Udacity for purposes of employment.

The Audacity of Udacity | MIT Technology Review
Uber for Education! says Thrun. Ha.

Udacity’s recently announced “Android nanodegree” was created with a $4 million investment from Google. It’s a six-to-nine-month program costing students $200 a month and promising to teach them everything about programming for Android, from the fundamentals to building apps. Projects are graded by Udacity’s network of 300 global code reviewers. As he explains to Business Reports senior editor Nanette Byrnes, those contractors are a key part of Thrun’s current vision for Udacity—a departure from the more common MOOC (massive open online course) model that the company initially seemed to be following, in which professors lecture and students do problems independently online.

Teaching students to master a topic, difficult in any classroom, seems to be one of the biggest challenges facing online learning. You say your approach works. How does it?
We very deeply believe, very passionately believe, that learning by doing trumps learning by listening. We believe the ultimate experience that really makes the master is to do something, build something, invent something, design something, code something. At Udacity, we built an Uber-like platform. With Uber any normal person with a car can become a driver, and with Udacity now every person with a computer can become a global code reviewer. And the mechanics for the code reviewer are the same: you’re being paid per code review, and you’re being assessed by your students. Our global code reviewers, on average, out of a five-point possible score, get 4.8 points. They give students back a very insightful and detailed, human-level, expert-level review of their work, typically within two hours, including detailed feedback on coding style, what works, what doesn’t work, and so on. Just like Uber, we’ve made the financials line up. The best-earning global code reviewer makes more than 17,000 bucks a month. I compare this to the typical part-time teacher in the U.S. who teaches at a college—they make about $2,000 a month.

Universities have become more and more exclusive … Industry says the opposite: make it as cheap as possible so we can reach everybody.

Is this particularly applicable to teaching coding? Can this translate to other fields as effectively?
I want to be careful not to say every field, but in many, many fields, you learn by doing and not by listening. Fields we are not going to engage in would be something like tennis or violin, where your own practice is absolutely fundamental. But in all my life, honestly—be it math, be it finance; I’ve done some medical studies, I recently became a pilot and learned to pilot a plane—in all these studies the mechanism is quite similar: the most effective learning environment is often one where the student gets to practice something under the guidance of someone more experienced and then gets personalized feedback on how they are performing.

The MOOC revolution that wasn’t
Not clear to me whether she'd like them whatever rhetoric they used.

But Thrun and other MOOC founders seem less than concerned about living up to their earlier, lofty rhetoric or continuing that tradition of bringing education to an underserved population. True, they haven’t entirely abandoned their rhetoric about equal access to educational opportunities. But they’ve shifted to what’s becoming a more familiar Silicon Valley narrative about the future of employability: a cheap and precarious labor force. That’s the unfortunate reality of “Uber for Education.”

When an algorithm isn’t… — Medium
Uses a cooking analogy to explain how machine learning works. Imagine, he says, a recipe, that you used frequently but you've lost the book it was in. And you go through a trial and error method of making that same food and you achieve something reasonable. But what you probably achieve is not what the original recipe was - and it would not be the same thing that your doppelganger somewhere else might get to. So that's the problem with machine learning algorithms, we don't quite know if they work not even their creators.

edx-notes-api: Feature development scale planning - Google Groups
What does scale mean? One more dimension

I'm Justin Abrahms, an engineer with MIT's ODL. I'm working towards
extending edx-notes-api to support collaborative annotations.

One of the open questions is around scaling the service. Based on
others we've talked to around existing annotations usage, there are
single courses that have 100k-ish notes per course.  The addition of
comments will compound that a great deal, I'd imagine. We don't have
clear numbers on exactly how commenting will change that, as this
isn't a feature the existing systems we investigated support.

Given that I'm possibly going to throw a few million rows into this
database (ElasticSearch & MySQL), what questions do you have for me?
What things should I be preparing so that we don't run into snags when
it's go-live time?

Summit on MOOCs inspires global research collaboration | The University Record
Coursera partners summit on MOOC research

“The goal of this summit is to build a research community, doing analysis and experimentation,” said Christopher Brooks, a research fellow in the School of Information and director of learning analytics and research at DEI.  “There are 118 Coursera partners currently, but not all of them have the capacity to do research.”

And while Coursera is where much of the MOOC activity began, Brooks said, the information of interest is broad, so the group will not be created for a single platform and will be an open organization.  Other major platforms include NovoEd, FutureLearn and EdX. U-M is affiliated with Coursera and NovoEd.

T.C. Pong of the Hong Kong University of Science and Technology came to the summit because, he said, he was “interested in what everyone is doing” and wanted to tell participants “what the other part of the world in Asia is doing.”
