Issues of reusability of learning objects in web-based environment

Abstract

Learning object is a granular or reusable chunk of information that is media independent which can be developed once and delivered in multiple delivery mediums. Learning objects would be stored in digital repositories, where they could be easily accessed, recombined and reused within online courses. In an ideal world, these learning objects would be designed so that they could be adapted to fit different educational models, subject disciplines and levels of study. To fully realize the possibility of personalized and reusable educational content requires the establishment of standards for the design and description of learning objects. Without such standards, the value of learning objects is substantially reduced. This paper describes issues related to reusability of learning object such as learning objects standards and how to reuse learning object effectively by integrating machine learning techniques. Aspects of cohesion, coupling and freedom from specific contexts will be looked at in designs learning object to ensure that learning objects are reusable, and these aspects can be captured as design patterns that may be employed to produce reusable designs for learning objects
