An important concern in web based educational environment is the task of designing and preparing learner assessment, which would enhance the learning process. Currently the majority of Computer Assisted Assessment tools provide an assessment of the learners, without an analysis of the adaptive content presentation. In this paper we propose a logicbased formalism to characterize adaptive content...

This paper discusses the advantages of offering adaptive hypermedia functionality in the e-Learning context through adaptive hypermedia services. We think that this option bridges the gap between the complexity of authoring and the ease-of-use necessary for successful adaptive hypermedia. This paper presents an open architecture for adaptive e-Learning that would make these adaptive hypermedia ...

We address this issue of how to formally model the adaptive component used to tailor the content found within Adaptive Hypermedia (AH) learning systems. We take a structure-oriented approach in which emphasis is placed on the structures used to specify documents and their meta data, rather than their content.

In the past decade, a number of adaptive hypermedia learning systems have been developed. However, most of these systems tailor presentation content and navigational support solely according to students’ prior knowledge. On the other hand, previous research suggested that cognitive styles significantly affect student learning because they refer to how learners process and organize information. ...

Closed corpus AH systems demonstrate what is possible to achieve with adaptive hypermedia technologies; however they are impractical for dealing with large volume of open corpus resources. Our system Knowledge Sea II presented in this paper explores social adaptive navigation support, an approach for providing personalized guidance in open corpus context. Following the ideas of social navigatio...

A hypermedia application offers its users a lot of freedom to navigate through a large hyperspace. The rich link structure of the hypermedia application can not only cause users to get lost in the hyperspace, but can also lead to comprehension problems because users read information in an order not foreseen by the author. Adaptive hypermedia systems (or AHS for short) aim at overcoming these pr...

In this paper we focus on adaptive instruction and especially on the educational perspective that should underlie the development of web-based Adaptive Educational Hypermedia (AEH) systems used for Internet-based distance education. A design rational and guidelines are proposed for adaptive instruction in the context of AEH systems, which unify several processes that formulate system’s adaptati...

The design of adaptive e-learning systems has been approached from different points of view. Adaptive Educational Hypermedia (AEH) conceptual frameworks, usually decompose this problem into separate concerns: a User Model (UM), an Adaptation Model (AM), and a Domain Model (DM). Regarding Educational Modelling Languages (EMLs), they provide adaptation mechanisms such as the modelling of particip...
