Learning Objects in Instructional System Design

What are Learning Objects?

According to Barritt (2002), there are many ways to define the size and function of a "Learning object" (LO). An LO can be as large as a course or as small as a specific piece of any content, for example, a definition. In fact, the size and shape of an object is open to the organization to define, as there is no industry or educational standard at this time.

However, for Barrit, an LO is based on a single learning or performance objective that is presented through content, practice, and assessment items. Content, practice items and assessment items are built out of text and media elements. The LOs can be stand alone instructional materials or they can be a series of LOs. These LOs, or building blocks of instruction may function like any other instructional object in that they are available for reuse by the authors or by the instructors and can be delivered to the performers just-in-time.

Here are some articles on LOs and RLOs. I believe that these are used mostly in the business world and higher education training centers.

Reusable Learning Objects (RLOs) in Instructional Design

Implications for Instructional design

Currently, I am researching Reusable Learning objects for my article. Looking at the faculty training experience and my internship, I have found that they are being used everywhere but at different levels of training. Following is a very general explanation and definition of RLOs.

Reusable learning objects (RLOs) are context independent, transportable and reusable pieces of instruction that are digitally managed and delivered. As such, they provide untold opportunities for easy access to tailored learning and are slowly being implemented in some larger corporations. Hodgins (2000)states that learning objects:

"represent a completely new conceptual model for the mass of content used in the context of learning. They are destined to forever change the shape and form of learning, and in so doing, it is anticipated that they will also usher in an unprecedented efficiency of learning content design, development, and delivery."

I have added all the references with a new post on LOs. The instructional objects are mostly called LOs or RLOs in computer science and business and the choice of a term refers to the way they are used in different instructional contexts.

A new model for the 21st Century

4C/ID Model

This is an instructional model by van Merriƫnboer (2002) and other researchers. The basic model appears to be based on Cognitive Load theory that Sweller and Van Merrienboer (1988) have researched before.

The 4C-ID model is characterized by four components:

(1) Learning Tasks, (2) Supportive Information,
(3) Procedural Information and (4) Part-Task Practice. The tasks are ordered by a task difficulty and each task offers at the beginning a lot of scaffolding (Vigotsky, 1930) which is reduced as the learner progresses.

According to Merrienboer et al., (2002), " the 4C/ID-model addresses at least three deficits in previous instructional design models.

First of all, the 4C/ID-model focuses on the integration and coordinated performance of task-specific constituent skills rather than on knowledge types, context or presentation-delivery media.

Secondly, in the paper, the model makes a critical distinction between supportive information and required just-in-time (JIT) information (the latter specifies the performance required, not only the type of knowledge required). And third, traditional models use either part-task or whole-task practice; the 4C/IDmodel recommends a mixture where part-task practice supports very complex, "whole-task" learning. "
