Over the course of the IPT 525 class, I have to admit that confusion set in when we started to discuss Sharable Content Objects (SCOs). I started to wonder how they are related to Reusable Information Objects (RIO) and Reusable Learning Objects (RLO). Is a SCO the same as a RLO or are they different?
Let’s begin by looking at SCOs. SCOs are a component of the Content Aggregation Model (CAM) which is a component of the SCORM. The CAM is comprised of Learning Objects divided into three categories:
- Assets
- SCOs
- Content Organizations
The contents of the learning objects are described by metadata. In addition, CAM includes a definition of how RLOs can be packed, delivered, and used.
Now, let’s look at RLOs and RIOs. Discussions about RLOs and RIOs have occurred in many posts throughout this blog. RLOs were discussed in Reusable Learning Object Strategies and RIOs were discussed in Expanding on E-Learning: Instructional Architectures and Learning Objects. The bottom line is RLOs are comprised of RIOs. RIOs by themselves do not have any context. They are simply “chunks” of information. When gathered together under a RLO, they create context meaningful to the learner. This is illustrated in Cisco System’s Reusable Object Strategy.
It may be safe to conclude that although SCOs and RLOs are not the same, SCOs contain RLOs. That’s the way I see it, but I’m open to correction on this. After all, that was the purpose of this blog – to create a discussion with other students of E-learning and professionals working in the field.
