Learning
Objects
Overview
Learning objects
(or RLO - reusable learning object) have been the hype of the elearning
industry since 2001. They have been hailed as the future reality of learning...and
as idealistic, but unattainable view for education. Separating the hype
from reality is still an ongoing activity. Most likely, learning objects
will fall somewhere in the middle of all the speculation - between the
"next best thing" and "impractical".
In many ways,
learning objects trace their origin to the concept of Object Oriented
Programming (OOP) - a programming term referring to the creation of segments
of code that can be incorporated and reused in different areas. The view
is that if learning is designed properly, each object will be a self-contained
"piece" of learning. While opinions differ on the exact size
of a learning object, the following definition makes the most sense to
me: A learning object is a single learning objective with supporting content,
interaction, and evaluation.

objects have much potential in making online learning development
affordable. For learning objects to be truly effective, pools of RLOs
of sufficient size (and quality) are needed (i.e. institutional, national,
and international). |

Learning
Objects
This article focuses on the organization of learning objects using a learning
content management system. The visuals are very effective in explaining
how objects are managed and used...and he gets away with using jelly beans
to do this - that alone is worth the visit to the site.
LEARNING
OBJECT TUTORIAL
"Learning objects are the core concept in an approach to learning
content in which content is broken down into "bite size" chunks.
These chunks can be reused, independently created and maintained, and
pulled apart and stuck together like so many legos."
CETIS
CETIS is mainly concerned with elearning standards...which is a critical
resource for learning object developers. Broad and detailed resources
are available here.
IEEE
LTSC
"This standard will specify
the syntax and semantics of Learning Object Metadata, defined as the attributes
required to fully/adequately describe a Learning Object." Like it
says...this site focuses on metadata for learning objects.
Stephen's
Web
Stephen Downes has contributed significantly to the subject of learning
objects (dare I say guru??). Search his site for learning objects...an
incredible amount of information. See in particular: Learning
Objects.
Specifications
and Standards For Learning Materials
"The Internet has been good for education: over the last decade,
the trickle of content has become a flood, and educators have been quick
to integrate the largesse into courses and classroom practices; distance
education has mushroomed, and sophisticated systems for the delivery of
elearning are in place. However, the problem of interoperability remains
- writing Web-based courses is expensive, and educators need to be able
to share resources if courses are to be cost-effective."

LCMS=LMS+CMS
(RLOs)
This article provides a clear overview of learning objects and the role
of a learning content management system (LCMS). The graphics are very
helpful in visualizing the process of creation to reuse.
Learning
Objects Metadata
"The educational sector can profit in particular from the benefits
IT adds to the ways of learning. The core techniques exists, still the
integration into the curricula and the integration of learning environments
and traditional knowledge management systems and libraries cannot keep
up with the pace of technology development."

Good definitions of learning objects, extensive listing of repositories,
and an excellent bibliography.

Objects
of Interest
Article by Clive Shepherd describing learning objects.
Re-using
Learning Objects
"A major issue when utilising multimedia learning materials is the
extremely high cost of development. For those paying the bills and those
at the sharp end of teaching, many benefits are to be had if such material
can be re-used and shared by others."
reusability.org
"Many people are interested in reusability and learning objects because
they offer a solution to the teacher bandwidth problem. "Teacher
bandwidth" is a term describing the number of students a teacher
can service (think about the amount of data that can travel across a phone
line). In this sense teachers can be seen as bottlenecks that limit the
number of students who can gain access to educational opportunity. Or
the number of potential customers who can be paying for your instruction
at any given time. Pick your own paradigm."
CanCore
" The CanCore Application Profile will allow educators, researchers
and students in Canada and around the world to more easily search and
locate material from any online repository of educational objects. These
educational or learning objects can be as simple as individual web pages,
video clips, or interactive presentations, or as comprehensive as full
lessons, courses or training programs."
Learning
Object Repositories
Alexandria
"Alexandria is Canada's first national repository for educational
objects. It is the actualization of a vision to make digital educational
materials readily available to students, researchers and educators across
the country and beyond."
LydiaLearn
"Lydia Inc. is a privately held, technology-driven service company
providing worldwide access to eLearning resources. We're well on the way
to becoming the major provider of networked content management repository
solutions to the eLearning industry, and we are the only open marketplace
for accumulating and distributing learning content contributed by an growing
global community of learning developers."
Merlot
Propably the best-known (first?) learning object repository. Excellent
site.
Wisc-Online
Good example of a repository that has value to educators and industry.
Splash
This site (or at minimum the concept) has much potential.
"The Portal for Online Objects in Learning (POOL) Project is a consortium
of several educational, private and public, sector organizations to develop
an infrastructure for learning object repositories. We address the issues
of building such architectures including the metadata, software and hardware
considerations and bootstrapping the system with initial content. We also
make our tools available for download, to help set up similar infrastructures
elsewhere and to connect them to POOL. The main advantage of our solution
is that it can potentially embrace all nature of individuals and organizations
involved in the learning object economy."
eduSource
"The general vision of
the eduSource project is focused on the creation of a network of linked
and interoperable learning object repositories across Canada. The initial
part of this project will be an inventory of ongoing development of the
tools, systems, protocols and practices. Consequent to this initial exercise
the project will look at defining the components of interoperable framework,
the web services that will tie them all together and the protocols necessary
to allow other institutions to enter into that framework."
