Explanations are essential in the teaching process. Tracers are one possibility to provide students with explanations in an intelligent tutoring system. Their development can be divided into four steps: (a) the definition of the trace model; (b) the extraction of the information from this model; (c) the analysis and abstraction of the extracted…

The role of conceptual modeling in Educational Adaptive Hypermedia Applications (EAHA) is especially important. A conceptual model of an educational application depicts the instructional solution that is implemented, containing information about concepts that must be ac-quired by learners, tasks in which learners must be involved and resources…

Public radio can survive cutbacks in federal subsidies, but only if these funds are reduced no more rapidly than public radio can replace them with newly-generated audience-sensitive revenues (listener support and underwriting). A model developed in this analysis suggests a three-to-five year "glide path" to zero federal support. Public…

This paper reports on the latest development of the Virtual Apparatus (VA) framework, a contribution to efforts at the University of Melbourne (Australia) to mainstream content and pedagogical functions of curricula. The integration of the educational content and pedagogical functions of learning components using an XML compatible script,…

One of the problematic issues in the content development for learning environments is the process of importing various types of course material into the environment. This paper describes a method for importing material into the A&O open learning environment by introducing a material model for metadata recognized by the environment. The first…

This paper discusses the role of XML in library information systems at three major levels: as are presentation language that enables the transport of bibliographic data in a way that is technologically independent and universally understood across systems and domains; as a language that enables the specification of complex validation rules…

Describes a framework called scaffolded knowledge integration and illustrates how it guided the design of two successful course enhancements in the field of computer science and engineering: the LISP Knowledge Integration Environment and the spatial reasoning environment.

Traditionally, novice programmers have had difficulties in three distinct areas: breaking down a given problem, designing a workable solution, and debugging the resulting program. Many programming environments, software applications, and teaching tools have been developed to address the difficulties faced by these novices. Along with advancements…

This paper presents a reference framework to describe educational material. It introduces the PALO Language as a cognitive based approach to Educational Modeling Languages (EML). In accordance with recent trends for reusability and interoperability in Learning Technologies, EML constitutes an evolution of the current content-centered…

This paper discusses a computerized learning environment called TurtleGraph that is designed and developed to support collaborative problem solving. Within the learning environment, learners are requested to write computer programs to generate geometric figures. The instructional focus of the system is to enhance the learner's List Processor…

Discusses multimedia authoring systems based on an analysis of multimedia computer-assisted instruction (CAI) courseware and its development. Topics include the function design of authoring systems; building a model of a multimedia CAI authoring system; and production techniques of the authoring system, including hypermedia. (LRW)

Technology has potential for teaching soft skills--typically those that are culture, gender, and model based. Authoring software for training is still being refined and interactivity is not where it needs to be for many applications.(JOW)

Discussion of the need for training in new information technologies focuses on the development of a distance education model for training teachers in computer literacy. Explains individual and collaborative learning support and the authoring module, and presents the results of preliminary evaluations. (LRW)

The aim of the 2018 International Association for Development of the Information Society (IADIS) Cognition and Exploratory Learning in the Digital Age (CELDA) conference was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There have been advances in both cognitive…

Examines differences among groups of listeners to political talk radio using data from a survey of adults in San Diego, California, from the perspective of Grunig's situational involvement model. Among more active audience members, limited motivational data suggest that political talk radio served a mix of needs, including seeking political…
