This report describes DVI (Digital Video Interactive) technology, current authoring languages and tools, and the reasons for developing new tools and applications. The work described was performed by Betac Corporation as part of a Phase II Small Business Innovation Research project. Section I provides background information on DVI. DVI technology…

This paper presents the use of an XML grammar for two complementary projects--CHAMELEON (Cooperative Hypermedia Adaptive MultimEdia Learning Objects) and EIT (Enabling Informal Teamwork). Areas of applications are modular courseware documents and the collaborative authoring process of didactical units. A number of requirements for a suitable…

Describes "Glass-box Interpreter" a low-level program visualization tool called Bradman designed to provide a conceptual model of C program execution for novice programmers and makes visible aspects of the programming process normally hidden from the user. Presents an experiment that tests the efficacy of Bradman, and provides…

A study of 89 computer programming students in two instructional groups found that those using Visual Basic (VB) mastered programming design concepts as well as those using traditional BASIC. Concludes that VB is an excellent choice for a first programming course (high school or university) emphasizing sequence, selection, iteration, variables,…

This paper reports on considerations about the common basic functions and components for building a collaborative authoring environment. The paper aims to specify and systematize the technological issues towards the future standardization of such environments, based on the authors' previous research experiences. Standardization includes many…

Purposes of this study were to determine: (1) if analogies and elaboration and placement of the analogies help novices learning a computer-programming language; (2) if students' mathematics ability influences programming learning; and (3) the interaction effects between analogy and mathematics ability. Subjects were 156 college students. Results…

Presents a Web portal for multicast communication management, which provides fully automatic service management with integrated provisioning of hardware equipment. Describes the software architecture, the implementation, and the application usage of the Web portal for multicast delivery. (Author/AEF)

Discusses a user interface that simplifies NF Squared (non-first-normal-form) relational query formulation in which query specification remains compact and straightforward. This interface allows for nesting and general hierarchical structures and restructuring which provides for more effective retrieval and query formulation. (Author/JKP)

Creating educational software generally requires a great deal of computer expertise, and as a result, educators lacking such knowledge have largely been excluded from the design process. Recently, researchers have been designing tools for automating some aspects of building instructional applications. These tools typically aim for generality,…

"Design Inspection Reviews" are structured meetings in which participants follow certain rules of procedure and behavior when conducting detailed readings of design plans to identify errors and misunderstandings. The technique is widely used in the software engineering industry, where it is demonstrably more effective than testing at…

An important category of SMET digital library content will be highly interactive, explorable microworlds for teaching science, mathematics, and engineering concepts. Such environments have proved to be extraordinarily time-consuming and difficult to produce, while threatening the goals of widespread creation and use. One proposed solution for…

This paper presents a means of storyboarding in multimedia courseware design that uses Microsoft PowerPoint as a storyboarding tool. In six undergraduate and four graduate teacher-education technology classes, students designed multimedia courseware using HyperStudio/ToolBook with three different storyboarding methods--index cards, paper forms,…

This paper investigates how computer support for vicarious learning can be implemented by taking a principled approach to selecting and combining different media to capture educational dialogues. The main goal is to create vicarious learning materials of appropriate pedagogic content and production quality, and at the same time minimize the…

Discussion of the time needed to create computer-based instruction focuses on descriptive analyses of production data gathered from novice instructional designers and novice authors who used a commercial authoring system to produce computer-based lessons. Production ratios are explained, and future research plans are discussed. (Contains five…

This paper presents and discusses the results of a project in which seven teams of fifth and sixth grade students were involved in designing and implementing interactive multimedia resources in science for younger children, using the Microworlds(TM) Logo programming environment. It was found that students improved significantly in their science…
