The experiment described is an excellent opportunity to apply theoretical concepts of distillation, thermodynamics of mixtures and process simulation at laboratory scale, and simultaneously enhance the ability of students to operate, control and monitor complex units.

This demonstration of the use of a computer simulation research method based on the System Dynamics modeling technique for studying distance education reviews research methods in distance education, including the broad categories of conceptual and case studies, and presents a rationale for the application of systems research in this area. The…

Original research is reported on image digitizing, robot choreography, movement analysis, databases for dance, computerized dance notation, and computerized lightboards for dance performance. Articles in this publication are as follows: (1) "The Evolution of Dance Technology" (Judith A. Gray); (2) "Toward a Language for Human Movement" (Thomas W.…

Interactive computer-generated simulations that highlight psychological principles were investigated in this study in which 33 female and 19 male undergraduate college student volunteers of median age 21 matched line and circle sizes in six variations of Ponzo's illusion. Prior to working with the illusions, data were collected based on subjects'…

The purpose of this paper is to examine the validity of regression estimates when skewed dichotomous scales are used as independent variables. When Pearson product-moment correlations are used to measure zero-order associations involving dichotomous variables, the resulting coefficients underestimate the true associations. As a result, using…

Two manuals address self-advocacy and assertiveness training for college students with language learning disabilities (LD) and their tutors. Part I examines the positive use of assertiveness and self-advocacy. Assertiveness is distinguished from aggressiveness, and the importance of assertiveness in the lives of LD college students is underlined.…

A recurring problem in educational research is how to account for non-random selection that has restricted the range of the variables of interest in correlational analyses. Several expressions due to H. Pearson (1903) and presented in matrix notation by D. N. Lawley (1943-44) are commonly used in selection settings to adjust for samples chosen on…

Simulation studies of the performance of (potentially) robust statistical estimation produce large quantities of numbers in the form of performance indices of the various estimators under various conditions. This report presents a multivariate graphical display used to aid in the digestion of the plentiful results in a current study of Item…

This activity is designed to introduce college students to the concept of floods as natural hazards, to flood frequency analysis, to hazard adjustment, and to the mechanics of public policy formulation through a six hour laboratory exercise, culminating in a simulation game. (JH)

Some of the results of a recent systematic investigation of the rationale underlying the current interest in such essentially problem-oriented instructional modes as the case method and simulation teaching in librarianship are summarized. (Author/PF)

The growth and potential of simulation and gaming techniques are examined in pure science, applied science and mathematics. The contribution of simulations, simulation games and non-simulation games are separately assessed with selective illustrations; in particular, indications for using simulated, as opposed to "live," experiments in science…
