This study was designed to look for patterns of parental behavior by assessing styles of child rearing in a novel way--through responses on an interactive computer program simulating an average day in the life of a mother and a preschooler. Presented to each subject (39 mothers of preschoolers and a control group of non-mothers) were 30 common…

The results obtained from two basic types of pre-equatings of tests were compared: the item response theory (IRT) pre-equating and section pre-equating (SPE). The simulated data were generated from a modified three-parameter logistic model with a constant guessing parameter. Responses of two replication samples of 3000 examinees on two 72-item…

The use of computers in the classroom has been touted as an important innovation in education. This article features some recently developed software for use in teaching psychology and different approaches to classroom computer use. Uses of software packages for psychological research designs are included as are applications and limitations of…

This report describes the development of the Instructional Support System (ISS), a large-scale, computer-based training system that supports both computer-assisted instruction and computer-managed instruction. Written in the Ada programming language, the ISS software package is designed to be machine independent. It is also grouped into functional…

Traditionally, the errors-in-variables problem is concerned with the point estimation of the slope of the true scores regression line when the regressor is measured with error, and when no specification error is present. In this paper, the errors-in-variables problem is extended to include specification error. Least squares procedures provide a…

This report summarizes an investigation of the attitudes of elementary students, teachers, and parents toward the use of educational computer games and simulations in a teaching/learning situation. Following a statement of the project purpose and a literature review, the courseware selection process is described. (This process resulted in use of…

An increasing number of non-statistical software packages are being written as supplementary instructional materials provided free or at low cost for economics principles textbooks. This paper reviews the software programs currently available as ancillary material to several major texts and compares what is available as a group against what should…

An experimental tool is described for the investigation of the human control behavior for slow responding dynamic systems. The Program for Research on Operator Control in an Experimental Simulated Setting (PROCESS) is a simulation of a dynamic water-alcohol distillation system that can be used in research on operator training. In particular,…

Research indicates that there are numerous opportunities for educators to use computer technology in ways which are developmentally appropriate and which support or enhance preschool children's natural motivation to explore and discover. Since many of the misconceptions about preoperational cognition that form the basis for serious objections to…

A simulation is described in terms of its three major aspects: the scenario, the underlying model, and the instructional overlay. The major focus of this paper is the instructional overlay as the component that serves to optimize learning and motivation. Functions of simulations are identified as the acquisition of content, the application of the…

This bulletin focuses on the role of computer-assisted instruction (CAI) in environmental education programs. The utility of this approach in helping students learn in the cognitive, affective, and/or psychomotor domains is examined and its effectiveness is compared to other instructional devices and methods. Major topics are organized and…

The plotting of multivariate data using computer line-printers has become a popular means of quickly representing multidimensional data. While many plotting programs are available, there is a paucity of research regarding the validity and reliability of interpretations made by viewing such graphics. This study explores the validity of four…

When two biological simulations on evolution and genetics (one originally developed for a conventional university undergraduate course) were introduced into Open University distance education classes, the difficulties encountered required a reappraisal of the concept of using computer simulation for distance learning and decisions on which…

An Open University project was planned to develop a set of computer assisted learning (CAL) microcomputer programs for a second level, summer school physics course, scheduled to begin in 1982. Major project aims were the development of an underlying system to effectively use medium resolution graphics with a simple animation capability;…

A rationale is presented for viewing the decision-making process inherent in determining budget reductions for educational programs as most effectively modeled by a graduated funding approach. The major tenets of the graduated budget reduction approach to educational fiscal policy include the development of multiple alternative reduction plans, or…
