The Biggest Barrier to WebRTC Adoption is Lack of Awareness!

How Appear.in Led Me To WebRTC

The appear.in Tool Back in January 2014 in a guest post published on Sheila MacNeill’s How Sheila See IT blog I reported on our experiments with the appear.in tool. This service provides a lightweight video conferencing tool. As I described in the blog post “unlike Skype, no software needs to be installed and unlike Google Hangouts you do not need to sign up to the service“.

Although the blog post and subsequent discussion on Twitter generated some interest in the appear.in service of potentially much more significance is the emerging standard on which the service is based: WebRTC.

What is CEN TC 353 becoming?

The CEN TC 353 was set up (about seven years ago) as the European Standardization Technical Committee (“TC”) responsible for “ICT for Learning Education and Training” (LET). At the end of the meeting I will be describing below, we recognised that the title has led some people to think it is a committee for standardising e-learning technology, which is far from the truth. I would describe its business as being, effectively, the standardization of the representation of information about LET, so that it can be used in (any kind of) ICT systems. We want the ICT systems we use for LET to be interoperable, and we want to avoid the problems that come from vendors all defining their own ways of storing and handling information, thus making it hard to migrate to alternative systems. Perhaps the clearest evidence of where TC 353 works comes from the two recent European Standards to our name. EN 15981, “EuroLMAI”, is about information about learner results from any kind of learning, specifically including the Diploma Supplement, and the UK HEAR, that document any higher education achievements. EN 15982, “MLO” (Metadata for Learning Opportunities) is the European equivalent of the UK’s XCRI, “eXchanging Course-Related Information”, mainly about the information used to advertise courses, which can be of any kind. Neither of these are linked to the mode of learning, technology enhanced or not; and indeed we have no EN standards about e-learning as such. So that’s straight, then, I trust …

At this CEN TC 353 meeting on 2014-04-08 there were delegates from the National Bodies of: Finland; France (2); Germany; Greece; Norway; Sweden (2); UK (me); and the TC 353 secretary. That’s not very many for an active CEN TC. Many of the people there have been working with CETIS people, including me, for several years. You could see us as the dedicated, committed few.

The main substance of the day’s discussion was about two proposed new work items (“NWIs”), one from France, one from Sweden, and the issues coming out of that. I attended the meeting as the sole delegate (with the high-sounding designation, “head of delegation”) from BSI, with a steer from colleagues that neither proposal was ready for acceptance. That, at least, was agreed by the meeting. But something much more significant appeared to happen, which seemed to me like a subtle shift in the identity of TC 353. This is entirely appropriate, given that the CEN Workshop on Learning Technologies (WS-LT), which was the older, less formal body, is now acccepted as defunct — this is because CEN are maintaining their hard line on process and IPR, which makes running an open CEN workshop effectively impossible.

No technical standardization committee that I know of is designed to manage pre-standardization activities. Floating new ideas, research, project work, comparing national initiatives, etc., need to be done before a proposal reaches a committee of this kind, because TC work, whether in CEN, or in our related ISO JTC1 SC36, tends to be revision of documents that are presented to the committee. It’s very difficult and time consuming to construct a standard from a shaky foundation, simply by requesting formal input and votes from national member bodies. And when a small team is set up to work under the constraints of a bygone era of confidentiality, in some cases it has proved insurmountably difficult to reach a good consensus.

Tore Hoel, a long-time champion of the WS-LT, admitted that it is now effectively defunct. I sadly agree, while appreciating all the good work it has done. So TC 353 has to explore a new role in the absence of what was its own Workshop, which used to do the background work and to suggest the areas of work that needed attention. Tore has recently blogged what he thinks should be the essential characteristics of a future platform for European open standards work, and I very much agree with him. He uses the Open Stand principles as a key reference.

So what could this new role be? The TC members are well connected in our field, and while they do not themselves do much IT systems implementation, they know those people, and are generally in touch with their views. The TC members also have a good overview of how the matters of interest to TC 353 relate to neighbouring issues and stakeholders. We believe that the TC is, collectively, in quite a good position to judge when it is worth working towards a new European Standard, which is after all their raison d’etre. We can’t see any other body that could perform this role as well, in this specific area.

As we were in France, the famous verse of Rouget de Lisle, the “Marseillaise” came to my mind. “Aux armes, citoyens, Formez vos bataillons!” the TC could be saying. What I really like, on reflection, about this aspect of the French national anthem is that it isn’t urging citizens to join some pre-arranged (e.g. royal) battalions, but to create their own. Similarly, the TC could say, effectively, “now is the time to act — do it in your own ways, in your own organisations, whatever they are — but please bring the results together for us to formalise when they are ready.”

For me, this approach could change the whole scene. Instead of risking being an obstacle to progress, the CEN TC 353 could add legitimacy and coherence to the call for pre-standardization activity in chosen areas. It would be up to the individuals listening (us wearing different hats) to take up that challenge in whatever ways we believe are best. Let’s look at the two proposals from that perspective.

AFNOR, the French standards body, was suggesting working towards a European Standard (EN) with the title “Metadata for Learning Opportunities part 2 : Detailed Description of Training and Grading (face to face, distance or blended learning and MOOCs): Framework and Methodology”. The point is to extend MLO (EN 15982), including perhaps some of those characteristics of courses (learning opportunities), perhaps drawn from the Norwegian CDM or its French derivative, that didn’t make it into the initial version of MLO for advertising. There have from time to time in the UK been related conversations about the bits of the wider vision for XCRI that didn’t make it into XCRI-CAP (“Course Advertising Profile”). But they didn’t make it probably for some good reason — maybe either there wasn’t agreement about what they should be, or there wasn’t any pressing need, or there weren’t enough implementations of them to form the basis for effective consensus.

Responding to this, I can imagine BSI and CETIS colleagues in the UK seriously insisting, first, that implemention should go hand in hand with specification. We need to be propertly motivated by practical use cases, and we need to test ideas out in implementation before agreeing to standardize them. I could imagine other European colleagues insisting that the ideas should be accepted by all the relevant EC DGs before they have a chance of success in official circles. And so on — we can all do what we are best at, and bring those together. And perhaps also we need to collaborate between national bodies at this stage. It would make sense, and perhaps bring greater commitment from the national bodies and other agencies, if they were directly involved, rather than simply sending people to remote-feeling committees of standards organisations. In this case, it would be up to the French, whose Ministry of Education seems to be wanting something like this, to arrange to consult with others, to put together an implemented proposal that has a good chance of achieving European consensus.

We agreed that it was a good idea for the French proposal to use the “MOOC” label to gain interest and motivation, while the work would in no way be limited to MOOCs. And it’s important to get on board both some MOOC providers, and related though different, some of the agencies who aggregate information about MOOCs (etc.) and offer information about them through portals so that people can find appropriate ones. The additional new metadata would of course be designed to make that search more effective, in that more of the things that people ask about will be modelled explicitly.

So, let’s move on to the Swedish proposal. This was presented under the title “Linked and Open Data for Learning and Education”, based on their national project “Linked and Open Data in Schools” (LODIS). We agreed that it isn’t really on for a National Body simply to propose a national output for European agreement, without giving evidence on why it would be helpful. In the past, the Workshop would have been a fair place to bring this kind of raw idea, and we could have all pitched in with anything relevant. But under our new arrangements, we need the Swedes themselves to lead some cross-European collaboration to fill in the motivation, and do the necessary research and comparison.

There are additional questions also relevant to both proposals. How will they relate to the big international and American players? For example, are we going to get schema.org to take these ideas on, in the fullness of time? How so? Does it matter? (I’m inclined to think it does matter.)

I hope the essentials of the new approach are apparent in both cases. The principle is that TC 353 acts as a mediator and referee, saying “OK” to the idea that some area might be ripe for further work, and encouraging people to get on with it. I would, however, suggest that three vital conditions should apply, for this approach to be effective as well as generally acceptable.

  1. The principal stakeholders have to arrange the work themselves, with enough trans-national collaboration to be reasonably sure that the product will gain the European consensus needed in the context of CEN.
  2. The majority of the drafting and testing work is done clearly before a formal process is started in CEN. In our sector, it is vital that the essential ideas are free and open, so we want a openly licenced document to be presented to the TC as a starting point, as close as can be to the envisioned finishing point. CEN will still add value through the formal process and formal recognition, but the essential input will still be openly and freely licenced for others to work with in whatever way they see fit.
  3. The TC must assert the right to stop and revoke the CEN work item, if it turns out that it is not filling a genuine European need. There is room for improvement here over the past practice of the TC and the WS-LT. It is vital to our reputation and credibility, and to the ongoing quality of our output, that we are happy with rejecting work that it not of the right quality for CEN. Only in this way can CEN stakeholders have the confidence in a process that allows self-organising groups to do all the spadework, prior to and separate from formal CEN process and oversight.

At the meeting we also heard that the ballot on the TC 353 marketing website was positive. (Disclosure: I am a member of the TC 353 “Communications Board” who advised on the content.) Hopefully, a consequence of this will be that we are able to use the TC 353 website both to flag areas for which TC 353 believes there is potential for new work, and to link to the pre-standardization work that is done in those areas that have been encouraged by the TC, wherever that work is done. We hope that this will all help significantly towards our aim of effectively open standardization work, even where the final resulting EN standards remain as documents with a price tag.

I see the main resolutions made at the meeting as enacting this new role. TC 353 is encouraging proposers of new work to go ahead and develop mature open documentation, and clear standardization proposals, in whatever European collaborations they see fit, and bring them to a future TC meeting. I’d say that promises a new chapter in the work of the TC, which we should welcome, and we should play our part in helping it to work effectively for the common good.

Learning Analytics Interoperability – The Big Picture in Brief

Learning Analytics is now moving from being a research interest to a wider community who seek to apply it in practice. As this happens, the challenge of efficiently and reliably moving data between systems becomes of vital practical importance. System interoperability can reduce this challenge in principle, but deciding where to drill down into the details will be easier with a view of the “big picture”.

Part of my contribution to the Learning Analytics Community Exchange (LACE) project is a short briefing on the topic of learning analytics and interoperability (PDF, 890k). This introductory briefing, which is aimed at non-technical readers who are concerned with developing plans for sustainable practical learning analytics, describes some of the motivations for better interoperability and outlines the range of situations in which standards or other technical specifications can help to realise these benefits.

5 lessons for OER from Open Source and Free Software

While the OER community owes some of its genesis to the open source and free software movements, there are some aspects of how and why these movements work that I think are missing or need greater emphasis.

1. Its not what you share, its how you create it

One of the distinctive elements of the open source software movement are open development projects. These are the projects where software is developed cooperatively (not collaboratively, necessarily) in public, often by people contributing from multiple organisations. All the processes that lead to the creation and release of software – design, development, testing, planning – happen using publicly visible tools. Projects also actively try to grow their contributor base.

When a project has open and transparent governance, its much easier to encourage people to voluntarily provide effort free of charge that far exceeds what you could afford to pay for within a closed in-house project. (Of course, you have to give up a lot of control, but really, what was that worth?)

Interoperability Incubation and Pre-standardisation Activity – A View on Desirable Qualities

There is an important process that should feed into the development of good standards (that are used in practice) and this process is currently in need of repair and reformation. They key idea behind this is that good standards to support educational technology, to take our area of particular interest, are not created on a blank sheet of paper by an elite but emerge from practice, collaborative design, experimentation, selective appropriation of web standards, … etc. Good standards documents are underpinned by a thoughtful analysis of these aspects such that what emerges is useful, usable, and used. The phrase “pre-standardisation and interoperability incubation forum” is an attempt to capture the character of such a process. Indeed, some industry partners may prefer to see a collaboration to incubate interoperability as the real thing, with the formal standardization politics as an optional, and sometimes problematic, add-on. It is our belief that all except the suppliers with a dominant market share stand to benefit from better interoperability – i.e. common means to share common data – and that there is a great deal of latent value that could be unlocked by better pre-standardisation activity and interoperability incubation.

Cabinet Office Consults on Open Standards for Government – URI Patterns and Document Formats

Feedback is invited on three proposals by Feb 24th (and 26th). The proposals relate to the following challenges (which apply to UK government use, not the whole of the public sector or the devolved governments):

  • URI patterns for identifiers. These will be for resolvable URIs to identify things and codes within data published by government.
  • Viewing government documents. This covers access by citizens, businesses and government officials from diverse devices.
  • Sharing or collaborating with government documents. This extends the requirements of the previous proposal to cases where the documents must be editable.

What Could ITS 2.0 Offer the Web Manager?

ITS 2.0 videoBack in October 2013 the W3C announced that the Internationalization Tag Set (ITS) version 2.0 had become a W3C recommendation. The announcement stated:

The MultilingualWeb-LT Working Group has published a W3C Recommendation of Internationalization Tag Set (ITS) Version 2.0. ITS 2.0 provides a foundation for integrating automated processing of human language into core Web technologies. ITS 2.0 bears many commonalities with its predecessor, ITS 1.0, but provides additional concepts that are designed to foster the automated creation and processing of multilingual Web content. Work on application scenarios for ITS 2.0 and gathering of usage and implementation experience will now take place in the ITS Interest Group. Learn more about theInternationalization Activity.

Using standards to make assessment in e-textbooks scalable, engaging but robust

During last week’s EDUPUB workshop, I presented a demo of how an IMS QTI 2.1 question item could be embedded in an EPUB3 e-book in a way that is engaging, but also works across many e-book readers. Here’s the why and how.

One of the most immediately obvious differences between a regular book and an e-textbook is the inclusion of little quizzes at the end of a chapter that allow the learner to check their understanding of what they’ve just learned. Formative assessment matters in textbooks.

Learning Analytics Interoperability – some thoughts on a “way ahead” to get results sometime soon

The “results” of the title are the situation where increased interoperability contributes to practical learning analytics (exploratory, experimental, or operational). The way ahead to get results sometime soon requires care; focussing on the need and the hunger without restraining ambition will surely mean a failure to be timely, successful, or both. On the other hand, although it would be best (in an ideal world) to spend a good deal of time characterising the scope of data and charting the range of methods and targets, it is feared that this would totally block progress. Hence a middle way seems necessary, in which a little time is spent on discussing the most promising and the best-understood targets. i.e. to look for the low hanging fruit. This represents a middle way between the tendencies of the sales-man and the academic.

I have written a short-ish (working) document to help me to explore my own thoughts on the resolution of tension between these several factors, which I see as:
