Describes a computer program, designed for second semester organic chemistry courses, which graphically displays organic synthesis routes on a screen. (MLH)

Presents author's view of how computer graphics produced in the classroom enhance mathematical concepts teaching. Specific concepts and related graphics presented include the convergence of power series and the Central Limit Theorem. Formal versus informal instruction, computer assisted instruction versus teaching, and requirements for future…

An archive of still images in videodisc format becomes a powerful instructional tool when complemented by a computer data base system for selection and retrieval and programs to generate materials and manage image presentation. Considerations in using this potential include database design, a classification system, and computer-videodisc…

Investigated the effectiveness of three types of vocabulary annotations on vocabulary learning for English-as-a-Foreign-Language college students: the annotation only, text plus picture, and text plus picture and sound. Determined whether learners with certain perceptual learning styles benefitted more from a particular type of vocabulary…

This article presents Virtual Radiopharmacy Laboratory (VR LAB), a virtual laboratory accessible through the Internet. VR LAB is designed and implemented in the framework of the VirRAD European project. This laboratory represents a 3D simulation of a radio-pharmacy laboratory, where learners, represented by 3D avatars, can experiment on…

Among the old-school resources that the digital age is making obsolete, or at least less consequential, count the chalkboard. For decades, the chalkboard was the focal point of all instruction, the big screen on which teachers wrote out and directed lesson after lesson after lesson. Today, while chalkboards still exist, they are losing their…

This study examined the effect of structural and content characteristics of language tasks on foreign language learners' conversational negotiations. In a 2x2 Greco-Latin square design, degree of structural support of language tasks, students' degree of familiarity with German video segments, and task order were varied. Twenty-eight pairs of…

Computer-based mathematical cognitive tools (MCTs) are a category of external aids intended to support and enhance learning and cognitive processes of learners. MCTs often contain interactive visual mathematical representations (VMRs), where VMRs are graphical representations that encode properties and relationships of mathematical concepts. In…

This article is about a computer lab project in which prospective teachers used Geometer's Sketchpad software to create two-dimensional nets for three-dimensional shapes. Since this software package does not contain ready-made tools for creating non-regular or regular polygons, the students used prior knowledge and geometric facts to create their…

This article will describe research done at the National Institute of Multimedia in Education, Japan and the University of North Texas on the creation of a distributed Internet-based spoken language learning system that would provide more interactive and motivating learning than current multimedia and audiotape-based systems. The project combined…

While most microeconomics curriculums contain no reference to the use of microcomputers, spreadsheet packages adapt well to microeconomics courses. This presentation examines the following topics in the context of a microeconomics course: (1) The Microcomputer Spreadsheet Package--LOTUS; (2) The Spreadsheet Anatomy--cells, commands, menus; (3)…

This paper presents a slide presentation software that incorporates a concept map, which explicitly shows how the various slides (and other multimedia components) presented are related to each other. Furthermore, presentations are conceived as hypermedia systems, where the presenter can navigate among slides (and the concept map) instead of the…

Using computer graphics such as drawings, charts, and figures in textual instruction can enhance learning by providing a spatial concept of what is being read. It is important for instructional designers to determine the specific instructional objectives to be met, what level of comprehension they want learners to achieve, and how to use the…

We will argue that CALL can usefully be viewed as a subset of computer software engineering and can profit from adopting some of the recent progress in software development theory. The unified modelling language has become the industry standard modelling technique and the accompanying unified process is rapidly gaining acceptance. The manner in…
