A Proposed Conception of the domain Model for Adaptive Hypermedia

Abstract

In the context of adaptive learning systems, we are working on designing and developing the domain model, which is one of the three fundamental models that constitute the main architecture of adaptive hypermedia systems.The domain model describes how the elements (knowledge and concepts) of the course are structured. Although there is a lot of domain model proposed by several reference models like (MUNICH and AHAM), and by E-learning technical standards like (SCORM and CMI5). These proposed models do not respect the context and go beyond the definition of the domain model in the sense that they introduce elements managed by other models that lead to a non-optimized structure for adaptation processes. So, in this paper we will present our proposal of the domain model that respect and remains in the context of the definition of the model and also based on a completely new structure optimized for adaptation processes that we named "objective-oriented structure".

Implemented and Tested Conception Proposal of Adaptation Model for Adaptive Hypermedia

“…Finally, after the success of the tests and implementations that we realized on our model and in addition to our learner model already proposed [7], we are counting on a future work to develop the domain model and also to design an intermediary model that will exploit the learning content generated from the three models (learner model, adaptation model, domain model) to generate an adequate learning content for the target platform (desktop, mobile, web).…”

“…During our previous work [7], we developed a new conception of the learner model mainly based on six facets (personal information, knowledge and skills, historic, psychological profile, cognitive ability, emotional state). And as a next step, we have studied the two remaining models and noted that most of the proposed adaptation models are never implemented (lack of concrete implementation) due to the fact that during the design of these models the technical and programming implementation was not taken into consideration.…”

“…Some works neglect even a certain type of adaptation, we quote the work of (De bra, 2008) [7], which takes into account only two types of adaptation: adaptation of content and adaptation of links, however, there are two other types of adaptation: adaptation of the presentation and adaptation of the structure.…”

Intelligent Model Conception Proposal for Adaptive Hypermedia Systems

“…These three models mentioned above represent the core, the resources and the fundamental elements for the functioning of the adaptive hypermedia, these elements are first collected from scientific and academic works then connected and structured in a logical conception that we call a model. After studying and proposing new conceptions for each one of the three models, which we published in several papers [6] [7], we intended to start the development of our hypermedia adaptive. However, we first had to deal with two major problems, which are: conceptual flexibility and cold start.…”

Learning Materials Representation for Interoperability in Heterogeneous Environment

“…Other communities established other standards based on LOM. For instance, "Instructional Management System" (IMS) [25], and SCORM [26], [27]are based on IMS. To enable global search for learning objects (resources), we have suggested a Global Learning Object Identifier (GLOID).…”
