I see the lowest level learning objects as "those things" that you
use in your lessons. A lesson may comprise a number of small
learning exercises or focused activities. I would see these as
learning objects.
However the lesson is also a learning object. In this case it is a
learning object that makes use of smaller learning objects. I would
also see a paper or course as a learning object. Again these would
be composed of smaller learning objects.
My thinking is influenced by object-oriented modelling concepts
used in Information Systems. An object in the Information systems
context can be as small as a number and as big as a system. In
the system context, is is composed of a number of other objects.
The system appears to be a complex object but in reality it is only
as complex as its constituent objects.
It seems to me that the concept of composition used in object
oriented modeling is relevant to learning objects. I suspect that we
can also apply the concepts of encapsulation, coherency,
coupling, and possibly inheritance.
Inheritance may solve the issue of an object not matching the
pedagogy of a course. I might need to think about this further but it
does seem that re-definition of some portions of a learning object
may adapt it for a different pedagogy.
