Learning Objects
An interesting website and one that may
be of value to many of our members who want to know more about learning
objects is found at: www.reusability.org/.
An excerpt appears below:
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.
There are currently three main lines of research relating to learning
objects and the teacher bandwidth problem. They are presented below in
order of their current popularity...
- automation
Intelligent tutor system-style interests look to overcome the
teacher bandwidth problem by replacing the teacher with an intelligent
computer program that automatically selects and sequences learning objects
for students. You can find research that supports this type of work
in the Instructional Use of Learning Objects or Learning Object Design
and Sequencing Theory. Most commercial work in learning objects, as
well as the work of specifications bodies like ADL/SCORM and the IMS,
is focusing in this area. [If you go to the website, each of the blue
titles represents an active link.]
- by-hand
About two years ago we started a project to legitimize the efforts
of human beings who put learning objects together. Computers aren't
the only ones who can assemble and reuse existing resources in the service
of teaching and learning: teachers can do it, too! Our Instructional
Architect project provides tools for teachers to find and use learning
objects in their instruction. We talk about some of the issues facing
human learning object assemblers in terms of metadata and granularity.
There is also a general purpose defense of by-hand assembly.
- by-community
John Seely Brown and others continue to point to the value of
the informal learning that takes place in social groups without a formal
teacher. The Internet provides hitherto unknown access to large, diverse
social groups. Unsurprisingly, these groups collaborate to reuse existing
resources in extremely interesting ways. The "by-community"
research area is a strange nexus of self-organization, activity theory,
and economics. Our current understanding of Online Self-Organizing Social
Systems is limited, but we're just beginning some interesting research
with more help from the National Science Foundation. A book that may
be of interest to you is, The Instructional Use of Learning Objects
by editor, David Wiley. You can read the full text of the online
version of the book for free at: www.reusability.org/read/
The book is divided into five major sections.
- Learning Objects Explained
- Learning Objects and
Constructivist Thought
- Learning Objects and
People
- Learning Objects Implementation
War Stories
- Learning Objects and
the Future
The book can also be purchased. If you
are interested in a slow-paced interview with the editor, David Wiley,
and Andy Walker, both billed as learning object authors and experts, go
