grounded in the object-oriented paradigm of computer science.

build small (relative to the size of an entire course) instructional components that can be reused a number of times in different learning contexts

Moreover, those who incorporate learning objects can collaborate on and benefit immediately from new versions. These are significant differences between learning objects and other instructional media that have existed previously.

Supporting the notion of small, reusable chunks of instructional media, Reigeluth and Nelson (1997) suggest that when teachers first gain access to instructional materials, they often break the materials down into their constituent parts.

if instructors received instructional resources as individual components, this initial step of decomposition could be bypassed

The Learning Technology Standards Committee chose the term “learning objects” (possibly from Wayne Hodgins’ 1994 use of the term in the title of the CedMA working group called “Learning Architectures, API’s, and Learning Objects”)

provided a working definition

Learning Objects are defined here as any entity, digital or non-digital, which can be used, re-used or referenced during technology supported learning. Examples of technology-supported learning include computer-based training systems, interactive learning environments, intelligent computer-aided instruction systems, distance learning systems, and collaborative learning environments. Examples of Learning Objects include multimedia content, instructional content, learning objectives, instructional software and software tools, and persons, organizations, or events referenced during technology supported learning (LOM, 2000).

The proliferation of definitions for the term “learning object” makes communication confusing and difficult.

It would seem that there are almost as many definitions of the term as there are people employing it.

In addition to the various definitions of the term “learning object,” other terms that imply the general intention to take an object-oriented approach to computer-assisted instruction confuse the issue further.

Depressingly, while each of these is something different, they all conform to the Learning Technology Standards Committee’s  “learning object” definition. An in depth discussion of the precise meanings of each of these terms would not add to the main point of this discussion: the field is still struggling to come to grips with the question, “What is a learning object?”

At the same time, the creation of yet another term only seems to add to the confusion. While the creation of a satisfactory definition of the term learning object will probably consume the better part of the author’s career, a working definition must be presented before the discussion can proceed.

Therefore, this chapter will define a learning object as “any digital resource that can be reused to support learning.”

This definition includes anything that can be delivered across the network on demand, be it large or small.

This definition of learning object, “any digital resource that can be reused to support learning,” is proposed for two reasons.

First, the definition is sufficiently narrow to define a reasonably homogeneous set of things: reusable digital resources. At the same time, the definition is broad enough to include the estimated 15 terabytes of information available on the publicly accessible Internet (Internet Newsroom, 1999).

Second, the proposed definition is based on the LTSC definition (and defines a proper subset of learning objects as defined by the LTSC), making issues of compatibility of learning object as defined within this chapter and learning object as defined by the LTSC explicit

With that compatibility made explicit, the proposed definition differs from the LTSC definition in two important ways.

First, the definition explicitly rejects non-digital

The definition also drops the phrase "technology supported" which is now implicit, because all learning objects are digital.

Second, the phrase "to support" has been substituted in place of "during" in the LTSC definition. Use of an object "during" learning doesn't connect its use to learning

The definition adopted for this chapter emphasizes the purposeful use (by either an instructional designer, an instructor, or a student) of these objects to support learning

Armed with a working definition of the term learning object, the discussion of the instructional use of learning objects can proceed.

Instructional design theory and learning objects

Reigeluth

[I]nstructional design theories are design oriented, they describe methods of instruction and the situations in which those methods should be used, the methods can be broken into simpler component methods, and the methods are probabilistic. (p. 7).s11 {margin-left:0; line-height:2.400000; text-indent:36;}

Because the very definition of “theory” in some fields is “descriptive,” design theories are commonly confused with other types of theories that they are not, including learning theory and curriculum theory (Reigeluth, 1999a).

The following discussion takes a step in this direction, by recasting two of the largest issues in the learning objects area – combination and granularity – in instructional design terms

Combination

there is astonishingly little conversation around the instructional design implications of learning objects.

item (d) in the Learning Objects Metadata Working Group’s PAR (LOM, 2000) reads as follows:

To enable computer agents to automatically and dynamically compose personalized lessons for an individual learner

at this point a brief discussion of metadata, the focus of the Learning Object Metadata Working Group’s efforts, is necessary.

Metadata, literally “data about data,” is descriptive information about a resource

he Learning Objects Metadata Working Group is working to create metadata for learning objects (such as Title, Author, Version, Format, etc.) so that people and computers will be able to find objects by searching

​The problem with 7(d) arose when people began to actually consider what it meant for a computer to “automatically and dynamically compose personalized lessons.”

his meant taking individual learning objects and combining them in a way that made instructional sense, or in instructional design terminology, “sequencing” the learning objects.

The problem was that no instructional design information was included in the metadata specified by the current version of the Learning Objects Metadata Working Group standard.

​The lack of instructional design discussion at this standards-setting level of conversation about learning objects is disturbing, because it might indicate a trend.

Once technology or software that does not support an instructionally-grounded approach to learning object sequencing is completed and shipped to the average teacher, why would he or she respond any differently

Wiley (1999) called this “the new CAI – ‘Clip Art Instruction’” (p. 6).

Discussion of the problem of combining learning objects in terms of “sequencing” leads to another connection between learning objects and instructional design theory.

Granularity

The most difficult problem facing the designers of learning objects is that of “granularity” (Wiley, et al., 1999).

How big should a learning object be?

Reuse is the core of the learning object notion, as generativity, adaptivity, and other –ivities are all facilitated by the property of reuse.

designating every individual graphic and paragraph of text within a curriculum a “learning object” can be prohibitively expensive

David Wiley and Rory McGreal urge universities to open their content; Wiley further envisions the future of education consisting of learner-generated materials;

Building rhizome-like learning networks can foster an environment more conducive to continuous knowledge acquisition and constructio

This does not match the way our brain process information, as we are better at learning incremental chunks of knowledge in a meaningful and authentic context.

Dave Cormie

Clark Quinn’s idea of slow learning

Here Jon Dron reminds us that tools themselves are not technology

Dron’s definitions of hard vs soft technologies relevant to both formal and informal learning, further help us to undertand that soft technologies are perhaps more useful in building learning and support communities and equipping learners with the ability to  navigate information in networks, thereby promoting lifelong learning.

The learners will end up leading the way, as they should.

The bolded items above really represent one version (and certainly not the only one) of the complete package – open content, open learning support, and open badges that help you demonstrate competence to an employer.

• Combine these and other business models to generate enough revenue so that (1) the marking service can be free in addition to all the badge related materials being openly licensed and (2) employers will respect and recognize the badges resulting from the process.

- An initial list of OER (e.g., OLI courses) and Q/A services (e.g., StackOverflow.com or OpenStudy) which will help individuals develop the skills necessary to obtain the badges

If a digital artifact released under a CC BY license is posted on a public website it would qualify as an open educational resource for everyone with internet access. However, if a teacher downloaded a copy of the OER and placed it inside a learning management system it would suddenly cease to be an open educational resource – even though the resource hadn’t changed.

The efficacy ideal is not realizable in practice. Intuitively we would want the ideal OER to support the educational goals of every user, and some definitions limit OER to “high-quality” materials. However quality, like beauty, is in the eye of the beholder. A resource considered very high quality by an English speaking undergraduate might be very low quality for an English speaking primary school student or a Spanish speaking undergraduate.

While everyone wants the OER they use to be high quality for them, it is meaningless to talk about OER being “high quality” without simultaneous reference to the user.

citation levels of articles that are published online versus those that are in closed access journals. Hajjem, Harnad and Gingras (2005) compared 1,307,038 articles across a range of disciplines and found that open access articles have a higher citation impact of between 36 and 172 per cent. So publishing in an online, open manner aids in the traditional measures of citation.

This section will look at the most concrete realisation of the open education movement, namely that of open education resources. In particular I want to revisit the notion of granularity and how changes in this, afforded by new technologies, are changing scholarly behaviour.

Zittrain (2008) terms ‘generativity’, which he defines as ‘a system's capacity to produce unanticipated change through unfiltered contributions from broad and varied audiences’. Little OERs are high in generativity because they can easily be used in different contexts, whereas the context is embedded within big OERs, which in turn means they are better at meeting a specific learning aim.

Big OER projects have a variety of models of funding, and Wiley highlights three of these demonstrating a range of centralisation: a centralised team funded by donors and grants (such as MIT), linking it into teaching responsibilities (as practised at Utah State University) and a decentralised collaborative authoring approach (e.g. Rice Connexions, http://cnx.org).

The reasons for this are varied, including technical complexity and motivation. One other reason which the OpenLearn team suggest is that the ‘content provided on the site was of high quality and so discouraged alteration’.

– a great resource that is essentially impossible to reuse, or a really poor resource that you can easily reuse

an interest in providing teachers real-time suggestions about the best way to use their next 10 minutes, are relatively new areas for me.

I would like to invite students to reflect on the practical impact on people they would like to their educational technology / educational research work to have.

defining an “open educational resource” in terms of copyright status is that the definition implies that all OER belong to the universe of copyrightable things. This explicitly precludes ideas, concepts, methods, people, places, events, and other non-copyrightable entities from being OER. (This helps us avoid some of the nonsense that went on with “learning object” definitions.)

onsequently, every community, individual, or institution’s ideal OER will be different, and it is important that we pause and acknowledge this.

Below, I work from the position that “an ideal OER would help every person in the world attain all the education they desire.” In this specific context, I believe the ideal OER would have three characteristics. It would: 1. Be always, immediately, and freely accessible by every person in the world 2. Grant the user the legal permissions necessary to engage in each and every possible usage of the resource with no restrictions whatsoever 3. Effectively support the educational goals of the user

it is meaningless to talk about OER being “high quality” without simultaneous reference to the user

If a digital artifact released under a CC BY license is posted on a public website it would qualify as an open educational resource for everyone with internet access. However, if a teacher downloaded a copy of the OER and placed it inside a learning management system it would suddenly cease to be an open educational resource – even though the resource hadn’t changed.

Note, however, that a student with access to the high school library and enrolled in the class using the LMS still has access to these materials, so those copies of the resources simultaneously are OER to her while they are not an OER for others.

some definitions limit OER to “high-quality” materials. However quality, like beauty, is in the eye of the beholder.

The notion of access, and whether or not a specific OER is accessible, is highly context-dependent.

much of what makes an OER ideal is context specific

ideal to whom, for what purpose, to be accessed in what way, to be used in what fashion, etc
