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…

Complex decision-making environments often demand that a range of alternative strategies be identified and compared for their shared value in achieving desired ends. Simple parametric statistical procedures such as analysis of variance and discriminant function analysis can be used in such situations to compare (using selected criteria) the value…

This paper examined the rank transformation approach to analysis of variance as a solution to the Behrens-Fisher problem. Using simulation methodology four parameters were manipulated for the two group design: (1) ratio of population variances; (2) distribution form; (3) sample size and (4) population mean difference. The results indicated that…

The feasibility of using computer simulation to teach behavior management skills to special and regular education teachers in training was evaluated using microcomputer-simulated spelling lessons involving four pupils programmed to make off-task comments. After training, education students' management of off task behavior approximated that of…

Outlines Component Design Theory, which is based on the author's earlier Component Display Theory, and provides the instructional design guidance needed for experiential computer based instructional systems. Highlights include a contrast between tutorial and experiential instructional models, content structures, consistency rules, instructional…
