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…

Podcast is a digital recording of a radio broadcast or similar program made available on the Internet for downloading to a personal audio player. In other words, it's a digital audio file that is created, shared, and heard. The podcast is a viable alternative for delivering research content or lessons to students who need remedial or extended…

The IMS Learning Design specification aims at capturing the complete learning flow of courses, without being restricted to a particular pedagogical model. Such flow description for a course, called a Unit of Learning, must be able to be reproduced in different systems using a so called run-time environment. In the last few years there has been…

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…

Instructional strategies make a difference in whether students are engaged in learning and are profiting from their time in class. High schools, technology centers and middle grades schools are encouraging teachers to adopt new teaching techniques and are providing opportunities for teachers to work together to improve their instructional skills…

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…

As an instructional technology, cognitive apprenticeship has become increasingly important. Cognitive apprenticeship embeds the acquisition of knowledge and skills in their social and functional context and consists of six teaching methods: modelling, coaching, scaffolding, articulation, reflection, and exploration. SMALLTALKER is a…

This paper describes the proposed School Without Walls program in the United Kingdom, a television-centered project which is designed to deliver high quality nursery (preschool) education direct to children at a fraction of the cost of traditional educational television programming. The daily programs will present a selection of practical learning…

The Comprehensive Unified Physics Learning Environment (CUPLE) is a project that brings together innovative uses of the computer for physics teaching into a single, multi-purpose learning environment. The status of college-level introductory physics teaching is reviewed. In these courses, physics instructors have been forced to be satisfied with…

Digital video is becoming increasingly ubiquitous. Most camcorders today are digital, and computers are being advertised based on their video editing capabilities. Many exciting research projects are investigating how to search, visualize, and summarize digital video, but there is little work on new ways to support the use of the video beyond just…

Provides a case study of RadioSource.NET, an Internet broadcasting venture developed collaboratively by land-grant university communication departments to share resources, increase online distribution, and promote access to agricultural and natural and life science research. Describes planning, marketing, and implementation processes. (Contains 18…

Identifies and describes methods of compiling datasets, search interfaces and etymological metaphors and mythologies of three of the first generation of automated indexing systems: archie, veronica, and robots and search engines. (Author/JKP)

An intelligent advisor computer program designed to assist undergraduate computer science students in producing an entity-relationship diagram, a conceptual model of a database. The advisor helps students perform modeling exercises and monitors student performance. (MSE)

To avoid long strings of browser addresses, a Florida multimedia instructor learned to create his own Web pages and jump pages (links to other sites). This article explains how he arranged for a Web server, assembled source materials, and adapted features of PageMill, a page-authoring software. (MLH)

Discusses the time and expense required to create interactive multimedia courses, and describes the Synergy project that combines a performance support system with authoring systems to accelerate the design and development process. Examples of screen displays are included. (Author/LRW)
