The E-learning Curve at Edublogs

In reaching a satisfactory definition of learning objects, a search through the literature revealed three broad characterisations:

The main idea of ‘learning objects’ is to break educational content down into small chunks that can be reused in various learning environments, in the spirit of object-oriented programming.

(Wiley 2000)

[A]ny entity, digital or non-digital, that may be used for training, education or technology supported learning.

(LTSC 2002)

…modular digital resources, uniquely identified and metatagged, that can be used to support learning.

(NLII 2002)

From these descriptions, we can develop a working definition of a learning object:

A Learning Object is any digital resource that can be reused to support learning.

This definition contains the following attributes:

• Learning objects are digital – can be stored and delivered electronically
• Learning objects are a resource – they contain the total means available to deliver training and learning objects are reusable – a single learning object may be used in multiple contexts for multiple purposes.
• Learning objects must contribute to the transfer of knowledge.

Further characteristics of learning objects include that they are self-contained – each learning object can be taken independently, they can be aggregated – learning objects can be grouped into larger collections of content, including traditional course structures, that they are interoperable - that learning objects have the ability to exchange information and to use the information that has been exchanged (usually through a specification like AICC or SCORM), and finally that they are tagged with metadata – every learning object has descriptive information allowing it to be easily found by a search.
