Single-administration procedures for estimating the coefficient of agreement, a reliability index for criterion referenced tests, were recently developed by Subkoviak. The procedures require a distributional assumption for errors of measurement and an estimate of each examinee's true score. A computer simulation of tests composed of items that…

A Monte Carlo study investigated the ability of the ALSCAL multidimensional scaling program to recover true structure inherent in simulated proximity measures when data were missing. The program worked well with up to 60 percent missing data as long as sample size was large and random error was low. (Author/JKS)

The study of the dynamics of physical systems is of importance to all engineering students. LSSP, a Linear System Simulation Program, is used to study the behavior of physical phenomena and systems which may be represented to a good degree of approximation by linear models. Emphasis is placed upon the unity resulting from the mathematical…

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…

Describes three case studies of the Huntington II POLUT model, which was run on both the University of Waikato computer system and a bank of four TRS-80s. Prospects for the development of computer based environmental education in New Zealand are also discussed. (LLS)

Interim work is documented describing efforts to modify computer techniques used to recognize and process English language requests to an instructional simulator. The conversion from a hand-coded to a table driven technique are described in detail. Other modifications to a simulation based computer assisted instruction program to allow a gaming…

Conducted to design software partitioning techniques for use by the Air Force to partition a large flight simulator program for optimal execution on alternative configurations, this study resulted in a mathematical model which defines characteristics for an optimal partition, and a manually demonstrated partitioning algorithm design which…

Over 200 professionals from schools in Minnesota participated in a computer simulated investigation of psychoeducational assessment and decision making for handicapped children. Demographic data were collected from each subject; estimates of the incidence of various handicapping conditions and knowledge of assessment was evaluated by a pretest.…

The definitions provided for high order language (HOL) requirements for programming flight training simulators are based on the analysis of programs written for a variety of simulators. Examples drawn from these programs are used to justify the need for certain HOL capabilities. A description of the general structure and organization of the…

Two different uses of interactive graphics in computer-assisted instruction are described. Interactive graphics may be used as substitutes for physical devices and operations. An example is simulation of operating on man/machine interfaces, substituting interactive graphics for controls, indicators, and indications. Interactive graphics may also…

This report describes the development of several new computer based strategies for teaching troubleshooting principles to electronics technicians. The computer programs to implement these strategies were developed in part from software produced in previous contracts. The report documents an experiment in which those materials were presented to…

This research has as its basic premise the belief that physical and mental skills are highly similar, enough so in fact that computation paradigms such as the ones used in Artificial Intelligence research about predominantly mental skills can be usefully extended to include physical skills. This thesis is pursued experimentally by the…

A study of college faculty evolution at Colgate University using a computer simulation model demonstrates how such a model can be used in planning and policy development. The potential effects of changes in retirement and tenure policies at Colgate and their ramifications for the affirmative action program are discussed. (Author/JMF)

This paper will discuss the results of a series of computer simulations comparing the Rasch logistic model to a series of models departing to various degrees from its assumption of equal discrimination power for all items. The results have implications for test construction and test scoring, indicating how closely the conventional raw score…

A computer program was developed with the potential to: demonstrate the power and uses of computers to students of environmental interpretation; show the use of computers for modeling in the realm of environmental interpretation; and show the use of computers as learning tools for students of environmental interpretation. A computer simulation…
