A Repository for Learning Objects: Supporting the Reuse and
Repurposing of Redesigned Courses and Their Content
- Key issues from proof-of-concept implementation
-
-
-
-
-
- Concept of Reuse : Reusing and sharing resources for educational purposes is not a new concept.
- Like traditional paper-based materials, digital
learning materials can also be shared and reused
- Campbell (2003) describes a useful three step process for integrating learning objects into educational settings
The first step addresses interoperability.
- The content is decontextualized into discrete learning objects
Third step focuses on technological issues.
- This step considers user access and tools, adherence to international standards and specifications, and the configuration of repositories
Step two in which considers the educational
properties of the learning objects
- Insuring the learning objects are pedagogically meaningful is a major focus
- Submission of learning objects and metadata creation
- controlled vocabulary tool provides the following functions
Allow the metadata creator to add new terms to the controlled vocabulary through a
simple to use submission form
-
Let metadata creator click on a term in the online controlled vocabulary and have it
automatically pasted in to the Subject field
Provide an online version of a controlled vocabulary that metadata creators can link to
and have open when they are determining what terms to put into the Subject field
- Metadata application profile
Metadata is critical for any digital repository to support a variety of functions including
management and end user interaction.
- Functional requirements for the LOR
-
-
-
- Testing and evaluating the repository
- The project team conducted two assessments of the proof-of-concept
System-level functionality assessment used a checklist
based on the
- functional requirements identified at the outset of the project
- focused on three categories
-
-
-
For the end user testing, the project team created use scenarios, each of which presented a real
life situation to exercise functionality in the repository
- End user interaction with repository.
- This section briefly describes the look and feel of the repository along with features implemented for the proof-of-concept.
-
-
-
- Decomposition of course content
-
-
For purposes of the proof-of-concept, the goal was to demonstrate the various levels of granularity that can be considered
-
Lesson: Each lesson belongs to a unit, and each lesson has two or more topics
