A Toolkit to Develop E-Learning in an Open (XML) Environment

Returning from content development theory, the gratis/libre debate, and the pros and cons of each approach, this post will focus on the range Opensource.svg of tools that you need to develop e-learning content in a (relatively) open environment.

Now read on…

The key to developing e-learning courseware in an open environment is to use a production model that liberates instructional design and content authoring from your final media outputs. In my view, this means taking an XML-based approach to your e-learning development environment. I would suggest that you need tools and components like the following tools to create an effective authoring and delivering system:

Content Creation Tools

  • DocBook
  • XMLmind XML Editor (XXE)
  • GNU Image Manipulation Program (GIMP)
  • XSLT transformations and XS-FOP formatting object processors


Media Creation and Integration: OSS Tools

  • Audacity
  • CineFX
  • Kompozer
  • OpenOffice.org
  • GNU Image Manipulation Program (GIMP)

Media Creation and Integration: Free-to-use Proprietary Tools
  • Microsoft Producer 2
  • Windows Media Developer’s Kit
  • Garageband
  • iMovie
  • Jing

Content Delivery Platform
  • Apache / MySQL / PHP
  • Moodle
  • Joomla
  • Drupal

Optional Proprietary Tools
  • Adobe Flash
  • Camtasia
  • Roxio Easy Media Creator or Toast

I'll be discussing developing a production model using this toolkit, starting tomorrow.

E-Learning, the Cathedral and the Bazaar: Courseware Development Approaches

...or Top-down versus Bottom-up approaches to content design.

In his 1997 essay The Cathedral and the Bazaar, open source evangelist Eric S. Raymond suggests that

the closed-source world cannot win an evolutionary arms race with open-source communities that can put orders of magnitude more skilled time into a problem.
Raymond considers the development of software by traditional methodologies as analogous to building a mediaeval cathedral,
carefully crafted by individual wizards or small bands of mages working in splendid isolation, with no beta to be released before its time.
He asserts that all software could be developed using the bazaar approach, which he described as
a great babbling bazaar of differing agendas and approaches... open to the point of promiscuity.

In this so-called Bazaar Model, roles are not clearly defined. Gregorio Robles suggests that software developed using the Bazaar model should exhibit the following patterns:

  • Users should be treated as co-developers
The users are treated like co-developers and so they should have access to the source code of the software. Furthermore users are encouraged to submit additions to the software, code fixes for the software, bug reports, documentation etc. Having more co-developers increases the rate at which the software evolves. Linus' Law states that, "Given enough eyeballs all bugs are shallow." This means that if many users view the source code they will eventually find all bugs and suggest how to fix them. Note that some users have advanced programming skills, and furthermore, each user's machine provides an additional testing environment. This new testing environment offers that ability to find and fix a new bug.
  • Early Releases
The first version of the software should be released as early as possible so as to increase one's chances of finding co-developers early.
Frequent Integration
New code should be integrated as often as possible so as to avoid the overhead of fixing a large number of bugs at the end of the project life cycle. Some open source projects have nightly builds where integration is done automatically on a daily basis.
  • Several Versions
There should be at least two versions of the software. There should be a buggier version with more features and a more stable version with fewer features. The buggy version (also called the development version) is for users who want the immediate use of the latest features, and are willing to accept the risk of using code that is not yet thoroughly tested. The users can then act as co-developers, reporting bugs and providing bug fixes. The stable version offers the users fewer bugs and fewer features.
  • High Modularization
The general structure of the software should be modular allowing for parallel development.
  • Dynamic decision making structure

There is a need for a decision making structure, whether formal or informal, that makes strategic decisions depending on changing user requirements and other factors (i.e. in extreme programming).

In Raymond's view, most well-known OSS products including Linux, Apache, and the GNU Compiler Collection align with the Bazaar model.
In the 'traditional' Cathedral model (advocated in Fredrick P. Brooks, Jr. in The Mythical Man-Month), development takes place in a centralized fashion. Clearly defined roles including experts dedicated to designing (the architects), established management styles, and 'craftsmen' (developers) responsible for implementation all contribute build a pre-established design according to a pre-agreed blueprint.


He goes further to say that in order to preserve the architectural integrity of a system, its design should be done by as few architects as possible.

Interestingly, the Bazaar model comes close (in manifestation, if not in philosophy) to what Brooks in the 1995 Anniversary edition of his text describes as "shrink-wrapped software." Brooks suggests:

For the developer in the shrink-wrapped industry, the economics are entirely different from those of the classical industry... the starkly different economies have given rise to starkly different programming cultures.

(p.284)


Rather than the traditional Cathedral model,
The shrink-wrapped industry... [is] freewheeling and fiercely focused on getting the job done rather than on process. in this climate, there has always been a much greater recognition of the talent of the individual programmer, an implicit awareness that great designs come from great designers [my italics]. The start-up culture has the capability of rewarding star performers in proportion to their contributions... [i]t is not surprising that many of the stars of the new generation have gravitated to the shrink-wrapped industry.

(p.284)


More tomorrow as I discuss towards the implications of these two models for the e-learning industry.

Is Social Learning a fad? One Organization Seems to Believe So

Reflecting upon the growing adoption of Web 2.0 technologies in enterprises and organizations, about two weeks ago I wrote a post called Shiny new technologies used by dusty old professions. In it I considered that an ad hoc approach to adding Web 2.0-based learning channels without appropriate strategy, planning, and management could lead to a diminution of their effectiveness in the long term.

In response to my article, I received a comment from a person associated with an organization who had gone down this very road by implementing informal learning and knowledge-sharing channels (including FaceBook, LinkedIn, Twitter, and asynchronous content delivery) on an “as needed” basis, and who contradicted or declared against the points I made in my post.

Here are some of the assertions made in the comment:

  • I wrote that informal learning was “casual”
  • Regulated professional bodies do not undertake informal learning (supporting evidence to this was included via a link to the organization’s Continuing Professional Education overview document, available online)
  • Social Media is a “fad”
  • I “miss[ed] the point completely. Social media is nothing to do with e-learning.”
  • My name is Brian

Naturally I published the comment (as I do with every comment I receive unless it’s spam). The missive wasn’t e-mailed to me personally, but to my blog, so I assumed it was submitted to the public domain. About a week later, I composed a response to the comment and e-mailed it to my correspondent.

To date I have received no reply from them, so I considered the matter is closed. However, a few people who read the comment got on to me (privately) and said that the remarks that were made in the comment were so inaccurate and erroneous, that it was worth highlighting them to a larger audience.

In fact, they said, the comment was a distillation of the general lack of understanding of informal learning, e-learning, and Web 2.0, and should be addressed as a matter of credibility for L&D professionals, if nothing else. And also that my name is not Brian.

So, for your consideration, my rebuttal to the charge that “Social Media has Nothing to do with E-Learning.”

Now read on…

To whom it may concern:

Many thanks for taking the time to communicate with me. Firstly I need to apologize: as in many occupations (accountancy among them, no doubt), learning and development professionals sometimes use certain words and phrases in very specific contexts that extend their meaning beyond popular use. It simply didn't occur to me that any of the terminology in the blog article text needed further exposition, and I regret that lack of clarity has caused you to object to and attempt to refute the remarks I made in my blog post.

However, you have misquoted me, suggested that my article was inaccurate, and that I "missed the point completely" so I'm invoking my right to reply. I'd like to say that I hate having to do this, as it makes me come across as long-winded and boring, and I am neither. Nevertheless, I wish to address each of the remarks you made in your comment: I'd appreciate it if you would take the time to reflect upon what follows.

First the misquote: you state in quote marks that I wrote "informal and casual" somewhere in my text. Let me be crystal clear about this: there is nothing "casual" about acquiring skills, knowledge, and expertise. I take the activity (and my part in it) very seriously. I did use the term "ad hoc" but in a completely different context, I will address this later.

I would assert that you felt motivated to respond to me because you would argue for what Colley, Hodkinson & Malcolm call the "perceived inherent superiority" (2002, p.2) of formal learning over informal learning.

Let's get this formal/non-formal/informal business out of the way, because it's part of the first point you refuted. All learning occurs on a continuum (see Figure 1) with formal learning at one extreme, and informal learning at the other, and non-formal learning 'in the middle.' Now here's the good bit, so I'm going to place this in a paragraph all on its own:

Eighty percent of organizational learning takes place informally.

Gartner Research (2008, p.1).

You will note that the continuum illustrated below is on a horizontal axis, and that there is no hierarchical distinction between the learning modalities.

learning continuum

Figure 1. The Learning Continuum

It's apparent that a dichotomy exists between the paradigms of formal, goal-directed training programs and informal "learning at the water cooler" (Grebow, 2002):

it is difficult to make a clear distinction between formal and informal learning as there is often a crossover between the two

(McGivney, 1999, p.1).

For much of the forty years since the terms were first coined (Coombs, 1968, p.1.) there has been a great deal of debate as to the nature of formal, informal and non-formal learning; the components of each of the paradigms, their boundaries and their overlaps. It's an ongoing discussion in L&D, but at this juncture we can say that the distinctions between them have been recognized by the EU and the OECD among other organizations. The European Commission state:

Learning takes place in different settings and contexts, formal, non-formal as well as informal. Learning that is taking place in the formal education and training system is traditionally the most visible and the one likely to be recognized in the labor market and by society in general. In recent years, however, there has been a growing appreciation that learning in non-formal and informal settings is seen as crucial for the realization of lifelong learning, thus requiring new strategies for identification and validation of these 'invisible' learning outcomes. However, definitions and understandings of what counts as formal, non-formal and informal learning can vary between countries.

(Valuing learning outside formal education and training)

At EU level, the following definitions are used:

Table 1. Definition of learning types

Learning Type

Description

Formal Learning

Learning typically provided by an education or training institution, structured (in terms of learning objectives, learning time or learning support) and leading to certification. Formal learning is intentional from the learner’s perspective [my italics].

Non-formal Learning

Learning that is not provided by an education or training institution and typically does not lead to formalised certification. It is, however, structured (in terms of learning objectives, learning time or learning support). Non-formal learning is intentional from the learner’s perspective [my italics].

Informal Learning

Learning resulting from daily life activities related to work, family or leisure. It is not structured (in terms of learning objectives, learning time or learning support) and typically does not lead to certification. Informal learning may be intentional but in most cases it is non-intentional (or “incidental”/ random) [my italics].

Regarding your own organization, I notice that in Continuing Professional Education, under the section entitled 'Unstructured CPE' (p.3), it is stated that:

Unstructured CPE can be defined as any form of informal learning or development of day to day working skills achieved through self-study and/or informal training. Unstructured CPE can be measurable but is not verifiable [my italics].

Personally, I support Alan Rogers' view that a 'new paradigm' for learning exists, in which "most programs [are] partly formal and partly informal" going from formal to informal and from informal to formal in both directions along a continuum. Both forms of education are important elements in the total learning experience" (Looking again at non-formal and informal education - towards a new paradigm, 2004).

As you stated in the Silicon Republic article Number crunchers find social media a ‘tweet’ surprise "It's our job to support our members at each point in their career." Implicit in this statement is support for the ongoing, formal, certified professional development initiatives that are required to ensure your members achieve and retain the appropriate knowledge and skills to undertake their professional activities competently. I didn't question this facet of these activities at any point in my article.

Equally I'm sure you design, develop, and implement your formal training initiatives based upon Training Needs Assessments and Skill/Gap Analyses to remediate deficiencies in your members' current skillsets and knowledge.

The next point I'd like to clarify concerns e-learning, social media, and the Read/Write Web (or Web 2.0). E-learning has been characterized as:

The continuous assimilation of knowledge and skills by adults stimulated by synchronous and asynchronous learning events - and sometimes knowledge management outputs - which are authored, delivered engaged with, supported and administered using internet technologies.

(Morrison, D. 2004, p.4)

So while you confidently tell me that "Social media is nothing to do with e-learning" I have to tell you that you're wrong: it has everything to do with it.

I suspect you perceive e-learning to be that old pageturner-with-audio stuff that characterized e-learning 10 years ago, and is still occasionally foisted upon organizations like the yours for compliance and regulatory reasons.

You don't have to believe me if you don't want to, but believe your own reasoning faculties and reflect on Don Morrison's above definition carefully. You'll see that e-learning 'checks all the boxes' that characterize social media.

As you state, social media are a great way to communicate, engage with, and create dialog between communities of practice. This is what makes Web 2.0 technologies - and it's associated products like Facebook, LinkedIn, and Twitter, as well as related technologies like on-demand video, such valuable and effective learning channels. According to industry analysts Forrester:

Learning 2.0 - or informal learning - means that employees take charge of their learning. Specifically, employees decide when they need information, where to go for information, and how to get information from other resources.

(Schooley, C. 2007, p.3)

This approach delivers learning right when people need it via:

  • Delivering small pieces of searched for learning content
  • Providing collaborative interaction support
  • Making job aids, reference sites, and materials readily available
  • Bringing contextual learning to specific tasks while workers are on the job

Forgive me if I'm incorrect, but is this not exactly what your organization is doing?
And finally we get to The Point That I Apparently Missed.

Is social media a "fad"? No.

Everett Rogers' Diffusion of Innovation theory tells us that the technology is maturing and has entered the Mainstream Adoption phase. My view is that the shift in information transmission we're seeing will prove to be as socio-culturally important as the invention of movable type 500 years ago.
You say that social media is

one of many communication channels we successfully use to direct members to education and learning opportunities, class-based or online.

I say that it is a learning channel - as you yourself said "Many share war stories and know-how in the forums": this epitomizes informal (e-)learning in action.

I think now I can reiterate my point (remember the "ad hoc" reference?). The purpose of the blog post was to highlight the issues associated with adding new learning / social media channels without a strategy, a plan, a goal, and a set of learning outcomes. Now, as we know, ad hoc according to Webster's Online Dictionary means "for the particular end or case at hand without consideration of wider application." As I concluded my article:

...it's one of the advantages of a non- or informal approach to e-learning, but I would suggest that too much of a 'make it up as we go along' approach can lead to spreading finite resources too thinly for any of them to be truly effective.

Or, more prosaically, if you don't manage, and maintain your content delivery channels effectively, you will see fall-off in use, and enter what Gartner call the ‘Trough of Disillusionment’ where

[technologies] fail to meet expectations and quickly become unfashionable.

Consequently, they are abandoned. In online circles this is called "blogrot" named after the estimated 125 million out of 133 million blogs that are not updated regularly (Technorati, State of the Blogosphere, 2008). To counter this, organizations need to actively manage and maintain their content and their knowledge, or it can peter out and ultimately cease to be of value.

The purpose of my post then, was to commend your informal e-learning activities, but to temper that commendation by highlighting the requirement to keep up the momentum surrounding these activities, for if your initiative fails, it becomes that much more difficult to re-implement similar programs in the future. Indeed, I consult for institutions including UCC and the ECDL Foundation, assisting the development of their learning programs, so I have a substantial amount of experience in this domain.

I hope this detailed missive clarifies matters; I look forward to making your acquaintance at some point in our respective careers, and I wish you every success in your ongoing learning and development initiatives.

Best regards,
