Considers the problem of how to go from three coordinates to two. States that it is not a problem that mathematics students ordinarily encounter. Presents four methods of graphing three-dimensional figures on a two-dimensional computer screen. (PK)

Describes a microcomputer program that simulates the pattern of evolution and produces clade diagrams and summary statistics. Allows users to vary the odds affecting the fate of a species. (TW)

Discussion of problems encountered in educational software development in Japan is the second of a two-part series on evaluation of Japanese microcomputer-based software. Problems associated with content, learner attitude, and graphics presentation are described, and future challenges in simulation and integrating courseware with other teaching…

Describes a sequence of activities for experimenting with scaling and includes a method for revising any turtle graphic procedure so that it can be drawn to a variety of scales. (PK)

Discusses some of the attributes of effective tutorial software programs. Describes four science programs that focus on the physical and earth sciences, and highlights some of their features that are proposed as features of high-quality educational software. (TW)

Presents findings from a literature review on interactive videodisc technology, interactive videodisc-based training, computer-assisted instruction, and their translations into effective instructional applications. Issues in educational development and application, guidelines for using graphics and other video effects, instructor and student…

Discusses pedagogical factors influencing design and construction of sophisticated educational multimedia workstations, and presents an overview of the Multi-Media Authoring Language system, an experimental test vehicle providing a framework in which to conduct hardware, software, and interfacing experiments necessary to produce a solution to…

Reviews research findings on variables in computer screen displays and their effects on learning for use by purchasers or designers of computer systems for instructional purposes. Variables discussed include fatigue, density of displayed text, scrolling, upper-case vesus upper- and lower-case lettering, letter size, and graphics. Ten references…

A concept map is a graphical representation of a person's (student's) knowledge of a domain. Concept maps have been used in educational settings for some time and many computer-based implementations of interactive concept map building tools exist. These concept mapping tools often provide for a solely prepositional, primarily textual, knowledge…

Discusses attributes which are offered as set of standards to judge instructional software--those unique to design of microcomputer courseware and those included in design of all instruction. Curriculum role, modes of interaction, computer managed instruction, graphics, feedback, packaging, and manuals are noted. Fourteen references are included.…

Distance delivery is the technological means of conveying instruction. Author presents technological distance delivery systems (print, audio, electronic graphics, video, computer); identifies pedagogical issues (instructor/learner interaction, instructional strategies, motivation, feedback and evaluation); and discusses instructional implications…

Describes a study that used qualitative analysis to determine the scope and interjudge agreement of personality information communicated to computer-using classroom teachers through three types of children's drawings: freehand, graphics tablet, and Logo. Children's drawings as psychological assessment tools are discussed and gender, age, learning…

Analyzes, as a function of grade level, the representation of gender, competition, and violence in 17 top-selling software programs designed for mathematics education. Results indicate that mean percentages of violence, competition against the program and competition against a peer increase across grade level; mean percentages of female characters…

Describes a two-year Canadian project devoted to the development and formative evaluation of a graduated series of four graphics-based programing environments for young children, called pre-Logo Microworlds. Field tests of software and instructional materials are described, and classroom observations and teacher and student interviews are…

Outlines techniques used in the context of a sixth grade science class to teach database structure and search strategies for science using the AppleWorks program. Provides templates and questions for class and element databases. (Author/YP)
