In an earlier work I defined an extension of XML called Algorithm Markup Language (AML) for easy and understandable coding in an IDE which supports XML editing (e.g. NetBeans). The AML extension contains annotations and native language (English or Hungarian) tag names used when coding our algorithm. This paper presents a drawing tool with which…

Advances in the Google Earth virtual globe and the concomitant Keyhole Markup Language (KML) are providing educators with a convenient platform to cultivate and assess one's place location knowledge (PLK). This article presents a general framework and associated implementation methods for the online testing of PLK using Google Earth. The proposed…

Computer science core instruction attempts to provide a detailed understanding of dynamic processes such as the working of an algorithm or the flow of information between computing entities. Such dynamic processes are not well explained by static media such as text and images, and are difficult to convey in lecture. The authors survey the history…

Online learning material that students use by themselves is one of the typical usages of algorithm animation (AA). Thus, the integration of algorithm animations into hypertext is seen as an important topic today to promote the usage of algorithm animation in teaching. This article presents an algorithm animation viewer implemented purely using…

Hypertextbooks for Computer Science contents present an interesting approach to better support learners and integrate algorithm animations into the learning materials. We have developed a prototype for integrating a selection of the functionality of such a hypertextbook into the established Moodle LCMS. This article describes the goals and…

Describes hypermedia-based learning resources, especially those on the World Wide Web, and suggests providing learners with reflection support to guide them to successful knowledge construction during exploration in hyperspace. Discusses knowledge-structure visualization, which models the exploration process. (LRW)

Describes two stages of potential development that could make multimedia the core of an information infrastructure for educational reform: (1) incorporating hypermedia to enable knowledge construction by learners; and (2) using visualization and virtual communities to create artificial worlds. (16 references) (MES)

Discusses and examines two approaches to concept-based retrieval of hypermedia information that improve a user's ability to navigate large systems--term indexing with semantically coupled thesauri and semantic hyperindexing. Visualization of index structures is discussed, and an example, the Cube of Contents retrieval model for the "Active…

Empirical studies that focus on the impact of three-dimensional (3D) visualizations on learning are to date rare and inconsistent. According to the ability-as-enhancer hypothesis, high spatial ability learners should benefit particularly as they have enough cognitive capacity left for mental model construction. In contrast, the…

Discusses the possibilities for improving courseware and the courseware engineering process using visualization. Advantages and disadvantages of visualization are considered, including psychological, instructional, motivational, cross-cultural, and technical aspects; visual programming systems are described; adaptation and rapid prototyping are…

Progress on a hypertextbook on the theory of computing is presented. The hypertextbook is a novel teaching and learning resource built around web technologies that incorporates text, sound, pictures, illustrations, slide shows, video clips, and--most importantly--active learning models of the key concepts of the theory of computing into an…

Hypermedia computing now makes it possible to integrate media into interactive programs with the potential to expand the use of visualization in science, art, and other professional disciplines. After an overview of some visualization issues in hypermedia, a research project called "HyperGlyphs" at Rensselaer Polytechnic Institute in…

In the context of exploring educational hypermedia on the World Wide Web, this paper presents a history visualization that helps learners reorganize explored contents to find what Web sites they should visit next. Learning-by-exploration is discussed as it relates to educational hypermedia, including the "Get Lost in Hyperspace" problem,…

The Collaboratory Notebook is a networked hypermedia database that allows students to collaborate on scientific inquiries across boundaries of time and space. Developed as part of the Learning Through Collaborative Visualization (CoVis) networking testbed, sponsored by the National Science Foundation, this software expands on the idea of…

This paper describes a prototype software tool for support of peer-to-peer conversation in distance education courses in text-based asynchronous mode, utilizing the visual structure of multiple threads of conversation. The theoretical basis for this design is a comparative analysis of oral, written, and electronic communication that enables the…
