Discusses use of the computer to solve the specific scheduling problems in assigning umpires to American League baseball games and assigning crews of officials to Atlantic Coast Conference football and basketball games. Scheduling variables that complicate the process and make manual scheduling almost impossible are described. (MBR)

A general description of microcomputer-based spreadsheet software capabilities and their usefulness in library management analysis and planning are presented. Five specific spreadsheet models which apply to retrospective conversion cost and scheduling, COM and book catalog costs, and acquistions processing costs are discussed and displayed in…

Shocked by static? Mixed up about magnets? Curious about currents? Teachers can get past memorizing all those electricity-related formulas, rules, and procedures so they can understand the subject at a level deep enough to teach it with confidence and comfort. Here to help is "Electricity and Magnetism," the fifth title in the award-winning NSTA…

Examines the relationship between instructional design (ID) and courseware development, especially for multimedia and hypermedia systems. Discusses ID models; external and internal reasons for the neglect of models; characteristics of models suitable for multimedia and hypermedia development; and models integrating those characteristics: Guided…

Evaluates the scaffold designed as a dynamic modeling software tool called Model-It in terms of its ability to support learners' use of modeling practices. Discusses the continued empirical validation of types and instances of tool scaffolds. (Contains 50 references.) (Author/YDS)

Describes a collection of systematic theory-based analyses of a system prototype that inherited its control mechanisms from preexisting systems. Demonstrates that collective use of system and user modeling techniques provides insight into a complex design problem, enabling the examination of design decisions for users and implementation. Discusses…

Provides an applications-oriented view of algorithmic historiography and how it relates to understanding scientific paradigms. Discusses HistCite[TM], a program that allows scholars to identify significant works on a given topic; paradigm shifts; a genealogic approach; citation analyses; correcting variations in citations; and bibliographic…

Describes the Case Hierarchy, a model of the case system of unconstrained natural language, and ways in which the case system is specialized in a restricted domain. Results of a feasibility study which examined the utility of the Case Hierarchy and the Case Hierarchy Tool (an intelligent editor supporting the domain analysis process) are…

Provides commentaries on professional and personal experiences in the development of simulations in the study of international affairs. Describes the evolution in Simulated International Processes projects from a person-machine format to an all-computer simulation. Discusses work with the military, field work, teaching experiences, difficulties,…

Defines prototyping as an original version or model on which a completed software system for computer-based training is formed; examines the development process of a prototype; describes how prototyping can assist in facilitating communication between educational technology, software engineering, and project management; and discusses why…

Developing the National Information Infrastructure requires a broader understanding of standards development; and three models associated with software applications, the Internet, and facilities-based telecommunications are presented. Users are playing a growing role in standards activities, and consortia have emerged to accelerate standards…

Argues that the traditional reliance on scholarly research and publication for promotion and tenure needs to be reexamined as professors spend increasing amounts of time developing computer courseware. The creation of new models for teaching and research that will include educational computing as a valued part of the educational process is…

Discusses language comprehension and describes a technology for computer-aided text analysis called READWARE and software from the READWARE family called the Research Assistant that measures the relatedness of words or phrases by examining their letters. The theory of Letter Semantics is explained, and paradigms for text processing in information…

Discusses Prospero, a distributed file system which provides tools to help users organize INTERNET resources. The Virtual System Model, the basis for Prospero, is introduced. Possible ways of organizing and retrieving information are described and illustrated with a sample session. Plans for the future are considered. (11 references) (MES)

Discusses system modeling and specification as it relates to object-based information systems development and software development. An automated system model based on the objects in the initial requirements document is described, the requirements document translator is explained, and a sample application of the technique is provided. (12…
