A '' …learning object'' is "any digital resource that can be reused to mediate learning." (Wiley & Edwards, 2002).

Dalziel (2002) describes a learning object as “an aggregation of one or more digital assets, incorporating meta-data, which represents an educationally meaningful stand-alone unit.”

A Learning Object is …
Digital
Searchable “Chunk of data”
Usable in any learning environment
Able to be grouped or to stand alone
Transportable from course to course & program to program
Interactive
