Describes a problem-solving activity integrating a laboratory investigation with a database activity using Appleworks. Presents typical displays of the databases. The objective of the laboratory was to determine the identity of a pure substance by measuring physical properties and searching the database. (Author/YP)

This article describes how the method of reducing the scale of a graph can be used to illustrate many theorems in geometry concerning angle size. Four examples are presented. A computer program is provided to illustrate how such rescaling of figures can be implemented in LOGO. (Author/YP)

Discusses the current state of computer managed instruction (CMI) and the advantages it affords both teachers and students. Describes the learning objective as the focus of CMI. Notes the interaction of computer assisted instruction and CMI. Lists a directory of 16 CMI systems. (MVL)

Presented is a review of a computer learning package "Lab Partner & Lab Master" for Apple II computers. Hardware requirements, components, functions, costs, and student reactions are discussed. Graphic analysis capabilities are stressed. (CW)

Reviews three chemistry software programs at the high school and college general chemistry level for the Apple II family. Includes "Chemical Nomenclature and Balancing Equations,""Principles of Stoichiometry," and "Solubility." (MVL)

Announces the development of a videodisc module which provides access to the U.S. Department of Agriculture information network. Relates sources of information, module description, recommendations for use, and software specifications. Describes the equipment needed. (RT)

Issues connected with knowledge acquisition through the development of complex computer programs--Intelligent Tutoring Systems (ITSs)--are discussed. The components of such a system and its applications are considered, including: elicitation of knowledge, tutoring with incomplete/uncertain knowledge, self-improving tutoring systems, and…

Discusses Alabama's attempt to provide computer aided instruction in remedial and initial instruction. Describes the program's funding, obstacles, and mileposts. Lists five phases for program development of competency software. Notes that 125 mathematics and five reading programs are available. (MVL)

Examines features to consider when redesigning instructional materials to electronic format from print. Topics discussed include physical presence; human-computer interface; resolution and screen size; online help; interactivity; motion and sound; and software tools. Examples of screen designs are included. (Contains 11 references.) (LRW)

The spoken language occurring when primary school children work in groups at the computer was examined. Findings suggest that discourse accompanying highly structured software conforms well to the initiation/response/follow-up (IRF) structure, with the computer often taking the initiating role. The more open-ended the program, the more…

Describes the development of an interactive video simulation, the "Classroom Management Simulation," that teaches eight basic principles of classroom management to preservice teachers. Highlights include the instructional design process, including task analysis; the use of HyperCard for programming; and results of field testing. (LRW)

Presents a comparison of two types of compact disc (CD-ROM) foreign language tutorials: (1) those made by publishers who favor an immersion approach; and (2) those made by publishers who use grammar-based approaches. Both types of CD-ROMs address various age groups, skill levels, and learning styles. (JMV)

Investigated the effects of group size and exposure time in the use of a commercially prepared tutorial program or drill-and-practice software by 168 fifth and sixth graders. Found that exposure time was related to students' scores on posttests. Results suggested a need to examine allocated time in microcomputer learning situations. (LB)

The third in a series of 3 articles, a study of 30 students was conducted to test the effect of restructuring a unit on trigonometric identities around microcomputer activities based on the themes of educational undercurrents identified in Part II. Experimental-group students scored significantly higher relating trigonometric functions to their…

Describes an experiment that was conducted using a digital video course to determine the effects of multimedia interface capabilities on computer-assisted instruction, particularly on recall performance and attitude. Results are reported that indicate motion video is more effective than slides, and design guidelines are suggested. (34 references)…
