Stanford engineers have developed an open source MOOC platform called Course2Go that is different from the proprietary platforms developed and used by Coursera and Udemy.

What makes it different is

its early dedication to building and maintaining a totally open-source platform. This means that the platform aims to be both free of cost and of pricey IP, while professors are free to contribute to Class2Go’s code and get involved in the development of the platform, as well as to collaborate with other institutions and organizations.

Rather than build its own platform, edX has decided to make use of Course2Go.

Although not stated in those terms, Class2Go will no longer be focused on building its own, independent platform, and instead its team will devote all of its attention to helping edX go open-source. In other words, Stanford will be integrating all of the features of its existing Class2Go platform into the edX platform, using Class2Go’s infrastructure as an internal platform for online coursework for on-campus and distance learners.

As of June 1, the company said, developers everywhere will be able to freely access the source code of the edX learning platform, including code for its Learning Management System (LMS); Studio, a course authoring tool; xBlock, an application programming interface (API) for integrating third-party learning objects; and machine grading API’s. In addition, edX will look to encourage participation from third-party developers by providing technical and process guidelines as well as additional support.

At the same time, edX has announced that it has developed a tool for automatically grading essay-type answers based on the use of artificial intelligence.

The EdX assessment tool requires human teachers, or graders, to first grade 100 essays or essay questions. The system then uses a variety of machine-learning techniques to train itself to be able to grade any number of essays or answers automatically and almost instantaneously.

The software will assign a grade depending on the scoring system created by the teacher, whether it is a letter grade or numerical rank. It will also provide general feedback, like telling a student whether an answer was on topic or not.

The New York Times article also presents some of the standard criticisms to automated essay marking, which to date has serious issues regarding validity, i.e. nonsense answers that use the right words get highly graded, while valid answers that use non-standard wording are failed or marked lowly.

Comment

The development of an open source MOOC platform seems to me to not only make a lot of sense technologically (how many different MOOC platforms do we need?), but more importantly allows any institution to offer its own MOOC without having to go through commercial operators such as Coursera. This will substantially bring down the cost of participating in MOOCs for most institutions (see a later post coming shortly). However, more consideration needs to be given to less objectivist or behaviourist approaches to teaching when developing these tools. For instance, it would be good to see Course2Go developing software (and the accompanying human approaches) to manage discussion groups on a large scale.

The bigger question is when will these Ivy League engineers start talking to educators about pedagogy, educational validity, and the nature of learning? I have no objection in principle about researching and developing teaching approaches that will work on a very large scale, so long as they adequately deal with the essentials of teaching and learning, and not just build what is relatively easy to develop in engineering terms.

This is what makes the current focus within x-MOOCs so infuriating. There is clearly huge potential for some major breakthroughs in developing large-scale, low-cost education, but some recognition that this needs to be a team effort that requires educational as well as engineering input on an equal basis is absolutely essential, otherwise it can end up being an extremely dangerous and destructive development, given the weight given to Ivy League developments in the mainstream media.

A bill of rights for online learners?

Listen with webReader

Morris, S.M. and Stommel, J. (2013) A Bill of Rights and Principles for Learning in the Digital Age Hybrid Pedagogy, January 22

I’ve just caught up with this (work keeps getting in the way of blogging, damn it) so forgive me if you’ve already seen it. This statement has been developed by a group meeting in Palo Alto, California, and has some well-known names attached, such as John Seeley Brown, Audrey Watters and Sebastian Thrun.

It’s really in two parts, the first setting out a collection of rights for learners and the second a statement of principles for providers of online learning. You will need to read the full article to get a more detailed description of each, but here is a very brief listing:

Rights (of learners)

  • to access: ‘Everyone should have the right to learn.’
  • to privacy
  • to create public knowledge
  • to own one’s own personal data and intellectual property
  • to financial transparency
  • to pedagogical transparency
  • to quality and care
  • to have great teachers
  • to be teachers

Principles (to which online learning should aspire)

  • global contribution: ‘Online learning should originate from everywhere on the globe, not just from the U.S. and other technologically advantaged countries.’
  • value: ‘The function of learning is to allow students to equip themselves to address the challenges and requirements of life and work.’
  • flexibility: ‘Ideally, they [the best online programs] will also suggest and support new forms of interdisciplinary and cross-disciplinary inquiry that are independent of old gatekeepers such as academic institutions or disciplines, certification agencies, time-to-degree measurements, etc.’
  • hybrid learning: ‘online learning should …. be connected back to multiple locations around the world and not tethered exclusively to the digital realm. ‘
  • persistence
  • innovation: ‘Online learning should be flexible, dynamic, and individualized rather than canned or standardized.
  • formative assessment
  • experimentation
  • civility
  • play

Comment

I have to admit being somewhat puzzled, not so much by the rights and principles themselves, but why it is thought necessary to codify and then publicize them.

First, would not most of these rights and principles be subscribed to already by most people that support public higher education, at least in North America, Europe and Australasia?  (I can’t speak for the Chinese or North Korean governments.)

If that’s the case (and it may be worth discussing this more), then the issue then is not the goals but the means to achieve the goals. Online learning is one, but in no way the only, means to some of these rights and principles. It is also true that while many working in or supporting public higher education would subscribe to these rights and principles, we often fall way short of implementing them, for a variety of reasons, such as lack of adequate resources or a poor choice of priorities. But that’s another discussion.

The question then comes to my mind as to why it has been necessary to spend time discussing and agreeing on principles and rights that most people in public education already accept.

One reason I suspect is a concern that developments in online learning outside formal, public education have the potential to run roughshod over these rights and principles. For instance, highly selective, campus-based, elite universities, at least until very recently, have not subscribed to some of these rights and principles, yet are now ‘discovering’ open learning through MOOCs, while still denying many of these rights to potential on-campus students.

Also, there is probably concern that MOOCs themselves are being exploited, at least by some organizations, for commercial reasons and this may result in some of these principles or rights being ignored or trampled on.

However, it could also be that some working in elite institutions have discovered God, and He is open, and so they need some commandments or a bible.

Thus having a statement of such rights and principles may be valuable, although how these rights or principles can be enforced is not at all clear to me – and what’s the use of a right if it can’t be protected?

Over to you

Do you think setting out these rights and principles is valuable?

Do you think public higher education generally subscribes to or adheres to these?

Why do you think such a statement has been made? Is it trying to say more than it does?

Discussing drop-out rates in MOOCs

A good, balanced discussion about how ‘success’ in MOOCs should be measured, with some data about completion rates.

MOOCs forcing traditional academics to re-think their teaching

Lecture capture at MIT: we can do better

Rivard, R. (2013) Learning how to teach, Inside Higher Education, March 5

This is perhaps the most encouraging item of news about MOOCs so far (and also illustrates that edX is taking a more thoughtful approach to MOOCs than Coursera.)

The Provost of Harvard, Alan Garber, noted that because of the wide exposure that MOOCs offer to academics, they are wanting to ensure that their teaching matches or exceeds that elsewhere. “Our faculty are extraordinarily successful,” Garber said. “They are used to winning. And they don’t want to lose this game.”

At the same time, the Director of edX, Anant Argawal, admitted that there is certain learning sciences research that many faculty, including himself, had long ignored as they focused on their own disciplinary fields. “To me, these papers should be must-reads,” he said.

However, it is a pity they still haven’t discovered the mass of prior research on online learning, but at least there is a recognition here that MOOCs can and should improve their pedagogy.

Briefing on MOOCs for the Board of Governors

Listen with webReader

Green, K. (2013) Mission, money and MOOCs Association of Governing Boards Trusteeship, No. 1, Volume 21

Excellent discussion of the implications of MOOCs prepared for governing bodies of universities and colleges.

Some conclusions:

Comparatively few of the nation’s more than 4,000 degree-granting American colleges or universities …. have the personnel, instructional and technological infrastructure, reputation (brand), and available cash to invest in launching their own MOOCs

The key questions that board members, presidents, and provosts confront in the conversation about MOOCs really involve certification and credit:

  • How do/should we assess “prior learning” for students who come to us with a certificate of completion from a MOOC provider such as Coursera, edX, or Udacity?
  • Assuming we can assess prior learning, should we give course credit to students who have completed a MOOC? And if so, for what courses and from which MOOCs?

The fundamental questions boards should be asking include:

  • Why are we online? Is the movement to or expansion of online education consistent with the institutional mission? Does and will it serve and advance the institutional mission? Or is the key issue in the discussion about online education—including any conversations about MOOCs—money?
  • How do we assess quality—that of our own online offerings and those of others, including the MOOCs?
  • What will it take to achieve our objectives in terms of online learning—including human and financial capital, content expertise, the political will to change, and many other concerns?

Well worth passing on to decision-makers concerned about the likely impact of MOOCs.
