Discusses the need to take into account the effects of arrested fractional crystallization in the petrographic classification of volcanic rocks containing plagioclase phenocrysts. Describes the development and use of a computer program to accomplish this task graphically. (TW)

Argues that students should have dynamic perceptual experience with the concepts central to circular functions. Includes a computer program, designed for Apple II, to provide such experience. (PK)

Describes a CD-ROM, "Shakespeare's Life and Times," originally designed for a college-level survey course, but which is also a resource for advanced high school students. Discusses the design structure, graphic images and textual information, ways teachers and librarians can use the CD-ROM for instruction, and adaptations for…

Describes a program that used the concept of cross-age tutoring to introduce computers to kindergarten students with the help of sixth graders. The use of FunWriter and other software is described, the importance of graphics is emphasized, and benefits to both groups of students are discussed. (LRW)

Describes the Knowledge Gateway Project (KGP), a program that emphasizes intensive use of computer technology to help at-risk high school students. Teacher training in the use of Macintosh computers and appropriate software is discussed, self-paced lessons are described, and changes in student behavior are reviewed. (LRW)

A current project is underway to develop a multimedia system that would support the teaching and learning of Chinese characters, as well as provide a platform for conducting research into the cognitive aspects of Chinese language acquisition. Although the number of commonly used Chinese characters amounts to thousands, there are many structural…

This paper chronicles the Teaching Mathematics Using Interactive Videodisk (TMMUIV) pilot project. The project emerged in response to the need to train pre-service teachers in, among other things, the use of mathematics manipulatives. The project now can offer a video database and pilot instructional program that combines full-motion video,…

The purpose of this paper is to report specific motivational requirements within each motivation category of Keller's ARCS (Attention, Relevance, Confidence, Satisfaction) model (1991) based on data collected on students' reactions to a computer-assisted learning lesson that incorporated motivational strategies in its design. Interview techniques…

This paper explores the role of computerized simulations as a decision-modeling intervention strategy, and views the strategy's different attribute biases based upon the varying primary missions of instruction versus application. The common goals associated with computer simulations as a training technique are discussed and compared with goals of…

Compares two authoring tools that were developed to enable users without programing experience to create and modify software. HyperCard, designed for Macintosh microcomputers, and ToolBook, for microcomputers that run on MS-DOS, are compared in the areas of programing languages, graphics and printing capabilities, user interface, system…

Discussion of the use of authoring systems for courseware development focuses on guidelines to be considered when designing authoring systems. Topics discussed include allowing a variety of instructional strategies; interaction with peripheral processes such as student records; the editing process; and human factors in computer interface design,…

Describes study that was carried out at the University of Calgary to determine how elementary school children conceive of computer-related tasks and how this information might be used to generate animated icons for educational software. Child-computer interaction is discussed, and differences in responses between three age groups are examined. (10…

Discusses problems with composition writing that beginning or learning disabled students may have and highlights the use of computer programs to encourage both elementary and secondary school students. Topics discussed include group lessons, sign makers such as "Print Shop," and menu driven graphics and text integration programs. (12 references)…

Describes a spreadsheet system that enables students, teachers, and curriculum developers to use Microsoft EXCEL's database and graphics capabilities in the science classroom. System design goals are explained, examples of system applications are given, and possible future developments are discussed. (15 references) (LRW)

Examines problems surrounding traditional assessment and evaluation in education and suggests ways to broaden the methodology as well as the validity of the assessment process. A study of elementary school students is described that used computer-generated assessment involving graphic feedback with and without text to study motivation and…
