DECP 05: Developing e-Content
The SCORM Content Aggregation Model
The SCORM CAM has three types of information which are the content model, metadata and content packaging.
(i) SCORM Content Model
The model describes the SCORM components used to build a learning experience from reusable learning resources. SCORM content model is made up of three types of content: assets, SCO and Content Aggregations.
* Assets:- These are learning contents in their most basic forms, composed of electronic representations of media, text, images, sound, web pages, assessment objects etc which can be delivered to a web client.
* Sharable Content Object:- A collection of one or more assets. A SCO represents the lowest level of granularity of learning resources. One or more SCOs can be aggregated to form a higher-level unit of instruction that fulfills higher level of learning objectives. One of the SCOs should implement the prescribed methods to interface with LMS. SCO can be launched and tracked by LMS. The SCORM does not impose any particular constraints on the exact size of a SCO.
* Content Aggregation:- Is a map (content structure) that can be used to aggregate learning resources into a steady unit of instruction e.g. subject, chapter, topic etc. The content structure defines the taxonomic representation of the learning resources. It is like a table of contents to organize the sequence and navigation of content in a course.
