Educational microworlds are defined and their potential for developing learners' thought processes is hypothesized to be more realizable than has previously been thought. A structured programing methodology that uses a point-and-click technique and that requires little syntactic sophistication on the part of the participant is presented. (LB)

Considers the possibility of designing CAI (computer-assisted instruction) systems that are managed by semantic networks. Topics discussed include general descriptions of the suggested approach, lesson-presentation modes, and the architecture of a CAI system managed by a semantic network. (10 references) (MES)

Discusses whether educators should write their own computer-assisted instructional software, and describes four basic categories of tools teachers can use to produce courseware: (1) traditional programing languages; (2) authoring languages, including hypertext authoring languages; (3) authoring systems; and (4) authoring aids. Each category is…

Presents the geometric, software-ergonomic, and educative standards for interactive graphics systems envisioned for planimetric constructions and calculations in secondary mathematics instruction. Describes the geometric-didactic potentials of the MS DOS-Version 1.6 of CABRI-Gomtre which is an Intelligent Tutoring System with the possibilities for…

Study examined the impact of word processing on sixth graders' writing and revision skills. Students used pencil and paper or word processors, or both, to write and revise compositions. There were significant revision differences. Word processing students corrected more and made fewer errors. Overall writing quality did not differ significantly.…

Presented is an overview of "Boxer," a multipurpose computational user-friendly medium, the focus of this special issue presenting research involving its use. With its roots in LOGO, the design of Boxer is described and an overview of the articles in the issue is given. (MDH)

Discusses the relevance of computer games to the design of computer-based training materials. Highlights include intrinsic motivation and computer-based games; the cultural distinction between work and recreation; the transient motivational effect of games; the differences in use of computer systems; hypermedia authoring systems; and virtual…

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…

This paper describes a speech teaching aid developed to assist in foreign language pronunciation teaching. The methodology used in designing the graphical user interface and the teaching plans are described, and the technical aspects (algorithms used, hardware requirements, etc.) are briefly discussed. (36 references) (JL)

Discusses bias in educational computer software by using examples of database programs to illustrate their cultural selection and amplification functions. Forms of knowledge control are examined, and results of a study that analyzed how gender, ethnicity, and the global perspective are portrayed in educational computer software are reported.…

Considers whether there are "good" or "bad" media, and the ability of teaching aids, by themselves, to solve educational problems. Questions central to the effective use of media are raised in the following areas: relationship between media and egalitarian education, creativity and motivation; relevance and quality; and role in…

Presents six principles for the design of adaptive computer-assisted language learning (CALL) programs for vocabulary that incorporate a theory describing quality in the learning outcome and linking it to the learner's approach. Highlights include interactivity; general architecture of a software system; and diagnosis and modification. (Contains…

Discussed are several different transformations based on the generation of fractals including self-similar designs, the chaos game, the koch curve, and the Sierpinski Triangle. Three computer programs which illustrate these concepts are provided. (CW)

The effectiveness of specific dimensions of adult mediation on preschoolers' self-regulation of a model consultation strategy was evaluated using microcomputer puzzle tasks. Findings suggest that children's acquisition of the model consultation can improve over a short period of time with culturally mediated instruction. (Author/GLR)

Compared the effects of LOGO Computer-Aided Instruction (CAI), and a standard curriculum without computer exposure among grade three Zimbabwean children. No significant differences were found between the groups exposed to LOGO and to CAI, but both achieved significantly greater gains that the groups without computer exposure. Results suggest that…
