As useful as LISREL may be in model estimation and testing, its most significant contribution to date is the encouragement and example it gives for right thinking about research and right planning of research. The encouragement to hypothesize the best possible model for the process that is the object of study, and to plan measurements that…

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…

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)

Model building techniques from Artifical Intelligence and Information-Processing Psychology are applied to human-computer interface tasks to evaluate existing interfaces and suggest new and better ones. The model is in the form of an augmented transition network (ATN) grammar which is built by applying grammar induction heuristics on a sequential…

Previous attempts to describe the "structure" of social systems have failed either because of the researcher's presuppositions about the system or because of his inability to deal with the massive amounts of data that a human system necessarily generates. Recent advances in computer software, Network Analysis Program (NEGOPY). have made…

A computer program to perform a Monte Carlo simulation of counting experiments was written. The program was based on a mathematical derivation which started with counts in a time interval. The time interval was subdivided to form a binomial distribution with no two counts in the same subinterval. Then the number of subintervals was extended to…

Because previous research by Bayman and Mayer (1983) suggests that individuals who attempt to learn their first computer language develop a variety of misconceptions of the meanings of individual programming statements, this study investigated whether it is possible to enhance beginning programmers' understanding of the programming statements…

An effort was made to operate a computer simulation of individualized self-paced instruction concurrently and in parallel with an actual conventional course. The simulation was in effect a management information system for instructors and students, with modifications as they were made by participants. A pilot program was run at Catholic University…

Considerable thought, research, and concern has been expanded in an effort to determine whether the assumption of a quadratic relation between a single predictor and a criterion violated the assumptions which Johnson and Neyman (1936) state for calculating regions of significance about interacting regressions. In particular, there has been special…

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…

Whenever one uses ordinary least squares regression, one is making an implicit assumption that all of the independent variables have been measured without error. Such an assumption is obviously unrealistic for most social data. One approach for estimating such regression models is to measure implied coefficients between latent variables for which…

Some 120 undergraduate students participated in experiments to learn how novice computer programers learn to interact with the computer. Two instructional booklets were used: A "rule" booklet consisted of definitions and examples of seven modified FORTRAN statements and appropriate grammar rules; the "model" booklet was…

Under the assumption that, with the exception of certain learned, retarded, and borrowed words, the bulk of any language undergoes sound changes that are regular over any given geographical area, over any given time span, and in any given sound environment, these sound changes have been reduced to logical terms and have been programmed to generate…

The work reported aims at the construction of a sufficient theory of transition in cognitive development. The method of theory construction employed is computer simulation of cognitive process. The core of the model of transition presented comprises self-modification processes that, as a result of continuously monitoring an exhaustive record of…

This paper reports on a computer simulation of cloze retrieval tasks. It first outlines the ideas that were assembled and translated into the model used to compose the simulation and describes the method used in developing the simulation. It then reports on a comparison of the time required by a computer and by human subjects in responding to…
