Engineering a Future for Web-Based Learning Objects

Abstract

This paper takes a critical look at current development efforts with learning objects for Web-based e-learning. It points out the limitations of these efforts and argues that they are still a long way off from realizing the potential of learning objects on the Web. The paper then proposes the notion of objectoriented learning objects to address several of the problems identified.

Intelligent Learning Objects

“…Some researchers concerning leaming objects, (Mohan & Brooks, 2003) propose an object-oriented approach. This architecture has a class of objects called LeamingObject, which is the superclass of all learning objects.…”

“…A Learning Object according to Downes (2001Downes ( ), (2002, Mohan and Brooks (2003), Sosteric and Hesemeier (2002), is an entity of learning content which can be used several times in different courses or in different situations. The use of reusable learning objects to create learning environments improves quickness, flexibility and economy.…”

“…Although all of this seems to be easier to deal with, we need smarter leaming objects. Mohan and Brooks (2003) point out several limitations of current leaming objects. According to them, an instructional designer must carefully examine each leaming object in which the task of finding the right object may be quite time consuming.…”

Improving Interoperability Among Learning Objects Using FIPA Agent Communication Framework

“…Metadata contain information to explain what the learning object is about, how to search, access, and identify it and how to retrieve educational content according to a specific demand. Mohan & Brooks (2003) point out the limitations of current learning objects. According to them, an instructional designer must carefully examine each learning object to find the right object.…”

“…A Learning Object, according to Downes (2001Downes ( , 2002, Mohan & Brooks (2003), and Sosteric & Hesemeier (2002), is a piece of learning content that can be used several times in different courses or in different situations. According to Downes (2001), the expense of developing learning materials for e-leaming can be large, but as the content of related courses tend to be similar, the cost of developing the learning materia!…”
