This paper describes the design of an adaptive user model and its implementation in an advanced Web-based Virtual University environment that encompasses combined and synchronized adaptation between educational material and well-known communication facilities. The Virtual University environment has been implemented to support a postgraduate…

Adaptive assistance in distributed learning environments (DLEs) provides new and exciting possibilities through the full exploitation of data captured from the interaction of the different actors with information processing, collaboration, and self-management tools. This paper presents a process to build adaptive assistance in a DLE. A DLE is rich…

This study summarizes recent achievements in the expanding development of man/machine communications and reviews current technological hurdles associated with the development of artificial intelligence systems which can generate and recognize human speech patterns. With the development of such systems, one potential application would be the…

This article proposes a categorization model for online distance education environments, based on two different aspects: interaction and content. The proposed categorization, which was based on the experience acquired in developing, implementing, and operating different remote training courses, is aimed at providing evidence to help educational…

Standardization initiatives in the field of learning technologies have produced standards for the interoperability of learning environments and learning management systems. Learning resources based on these standards can be reused, recombined, and adapted to the user. However, these standards follow a content-oriented approach; the process of…

Describes two models for using the Electronic Networks for Interaction (ENFI) systems in writing instruction. Identifies the aims as (1) advancing traditional interests of the English department; (2) encouraging collaborative writing; and (3) increasing student freedom. Provides examples of student writings resulting from the traditional teacher…

This paper argues that research findings from the study of teaching could be very useful in enhancing knowledge and tools for the design of both conventional and intelligent instructional software. It also suggests that if the ways in which teachers effectively conduct instruction are different and in certain ways better than other media, and if…

A person-centered model of instruction has been developed for use in designing instruction in virtual, Web-based environments. This model, based on the work of Carl Rogers, attempts to address several issues raised in the literature regarding: (1) the changing role of instructors and students; (2) the broadening of the notion of learning outcomes;…

The importance of the Extensible Markup Language (XML) technology family in the field of Computer Assisted Learning (CAL) can not be denied. The Instructional Management Systems Project (IMS), for example, provides a learning resource XML binding specification. Considering this specification and other implementations using XML to represent…

This paper presents and discusses the evolution of a metadata-based course portal, the Open Learning Repository (OLR). Different instructional models and learning principles are integrated in order to meet different learning and teaching strategies: different metadata models (domain model, instructional model, cooperative and structural model) are…

This paper describes a domain-specific repository based on the methodology for e-learning systems development. The methodology, which is based on information engineering and object-oriented technology, is used to support navigation for courseware development, designing the curriculum of e-learning components, and e-learning resources management. A…

The use of advanced learning technologies enables various new forms of collaborative learning and group assessment. This paper outlines a radically different model of student assessment to that traditionally used in most universities and other educational institutions. The model is particularly suited to those using, or seeking to use,…

Diagnostic Cognitive Assessment (DCA) is an alternative dynamic assessment. It aims at measuring cognitive processes for effective learning support and coaching. DCA is embedded in a digital coaching system (DCS) as an executive director. It contains three sub-models: Expert Knowledge Model, Inference Model, and Student Model. While the Expert…

A technology professional development initiative was launched in a school district with the goal of extending technology use in the classroom. For teachers to teach expertly, the aim was for them to "be the technology" by modeling technology use in the classroom, applying technology across the curriculum, applying technology to…

The purpose of this study was to develop a comprehensive model for local school technology professional development that facilitated technology integration into the curriculum. The local school technology committee conducted an informal performance analysis to determine a plan of action. As a needs assessment, stakeholders were surveyed to…
