The applications of a recently developed computer program for microcomputers in developing models in an institutional research environment are considered. The VISICALC program requires no user programming skills, is available for all major brands of microcomputers, and provides for easy exchange of information between users of different computing…

As psychologists increasingly employ more elaborate and comprehensive data collection schemes, sophisticated analytic techniques will play an ever more important role in understanding behavioral data. This paper outlines one such promising technique, Tucker's three-mode factor analysis, which enables the researcher to explore new taxonomic…

The first stage of a study on the potential for collaborative development in library automation involved a study of more than 150 recent reports and papers, and visits to library sites in the United Kingdom, Scandinavia, West Germany, and the United States. Systems models were advanced to provide a basis for testing development proposals. Further…

This paper discusses the Financial Analysis System (FAS), a software system for financial analysis, display, and modeling of the data found in the COMPUSTAT Annual Industrial, Over-the-Counter and Canadian Company files. The educational utility of FAS is also discussed briefly. (Author)

A computational method for weighted euclidean distance scaling (a method of multidimensional scaling) which combines aspects of an "analytic" solution with an approach using loss functions is presented. (Author/JKS)

This text provides educational administrators with a working knowledge of the problem-solving techniques of PERT (planning, evaluation, and review technique), Linear Programming, Queueing Theory, and Simulation. The text includes an introduction to decision-making and operations research, four chapters consisting of indepth explanations of each…

A quantitative model is described for the optimal assignment of students to courses for their complete high school careers. Model-generated student schedules are found to be unfailing in their conformity to all the constraints of the test high school's curriculum. (Author/IRT)

This report gives a managerial overview of the Life Cycle Cost Impact Modeling System (LCCIM), which was designed to provide the Air Force with an in-house capability of assessing the life cycle cost impact of weapon system design alternatives. LCCIM consists of computer programs and the analyses which the user must perform to generate input data.…

This paper examines the effects of learning time on student achievement. It begins by reviewing what is known about how time is allocated and utilized in schools and the effects of differing amounts of exposure to schooling on achievement. Several theoretical perspectives concerning how time spent affects achievement are briefly discussed. The…

The dangers of overlooking time-honored cautions in the making causal interpretations of data analyses from correlational studies when using highly sophisticated computer programs and their associated techniques are discussed. (JKS)

Describes an exercise (using Apple microcomputer) which provides an introduction to computer simulation as a biological research tool. Includes examples of students' modeling programs and partial program listings for programs developed by students from an original model. (JN)

These papers describe efforts toward the systematic improvement of a software environment called SOLO (Eisenstadt, 1978), which has been used with cognitive psychology students at the Open University in Great Britain and is geared towards the manipulation of assertional databases. The first paper, by Eisenstadt, Laubsch, and Kahney, provides an…

This research report discusses several efforts which were undertaken to assist PLANIT (Programming Language for Interactive Teaching) authors in the writing of team lesson scenarios. It also describes and illustrates the assistance given to two such authors who were engaged in the development of computer assisted instruction for training teams of…

PATN is a design for a machine problem solver which uses an augmented transition network (ATN) to represent planning knowledge. In order to explore PATN's potential as a theory of human problem solving, a linguistic approach to protocol analysis is presented. An interpretation of a protocol is taken to be a parse tree supplemented by semantic and…

Examines common curricular needs in written language instruction, and the advantages of using micorocmputers to teach descriptive writing. An example of an interactive computer-assisted instructional model for writing is discussed. Fourteen references are listed. (MER)
