Learning Objects: A Practical Definition
Rory McGreal
Learning objects (LOs) enable and facilitate the use of educational content online. Internationally accepted specifications and standards make them interoperable and reusable by different applications and in diverse learning environments. The metadata that describes them facilitates searching and renders them accessible.
LOs are sometimes defined as being educational resources that can be employed in technology supported learning. With appropriate metadata descriptions, they can be modular units that can be assembled together to form lessons and courses. A LO can be based on an electronic text, a simulation, a Web site, a .gif graphic image, a QuickTime movie, a Java applet or any other resource that can be used in learning.
Online, objects used for learning exist and interoperate at different levels of granularity. The simplest level is the content, information or knowledge object. This could be a simple text document, a photograph, a video clip, a three dimensional image, a Java applet or any other object that might be used for online learning. For example, a video clip from an international sporting event such as the World Cup would be an example of a simple media object. It becomes more useful for learners when a lesson is added to it. Many different lessons can be created from one component. This one video clip could form part of lessons in kinesiology, sports science, politics, history, media studies, and many other subjects could be created from this one video clip.
A diagram of these views of LOs is available in Figure 3. The north-south line represents the digital only/digital + anything dichotomy and the east-west axis represents the generic to learning specific continuum. The bottom left quadrant shows the extreme position of a LO as being anything, while the opposite quadrant includes both digital LOs with an ostensible learning focus and the more explicit digital LOs for specific implementations. The top left quadrant shows Los as anything digital opposing the bottom right quadrant showing LOs with a learning focus including non-digital objects.
