This article discusses the analysis of a decision-making process faced by contestants on the television game show "The Price is Right". The included analyses of the original and related problems concern pattern searching, inductive reasoning, quadratic functions, and graphing. Computer simulation programs in BASIC and tables of…

Studies the perceived effectiveness of four student projects involving videotape production, computer conferencing, microcomputer simulation, and rapid-cycling Brassica breeding for undergraduate plant breeding students in two course offerings in consecutive years. Linking of the computer conferencing and video projects improved the rating of the…

Discusses computer simulations in science education and presents the results of a study of 39 ninth-grade earth-science students to determine the effects of computer-simulated mineral identification activities on test performance. Results indicated no difference in test scores between the group using real minerals and the group using a computer…

The Virtual Gorilla Modeling Project--a professional development project--is a collaboration of middle and high school inservice teachers, Zoo Atlanta primatologists, science and computer educators, and students. During a 10-day professional development summer workshop, middle and high school teachers explore the world of the gorilla through…

Virtual Reality has been defined in many different ways and now means different things in various contexts. VR can range from simple environments presented on a desktop computer to fully immersive multisensory environments experienced through complex headgear and bodysuits. In all of its manifestations, VR is basically a way of simulating or…

This paper discusses issues of representation in the use of scientific visualizations, specifically those used for biomedical applications, and the implications of those issues to interface design. Topics addressed include the benefits of research into the generation of virtual simulation (virtual reality) and the importance of realism. (Contains…

A probability distribution was developed for the Andrews-Pregibon (AP) statistic. The statistic, developed by D. F. Andrews and D. Pregibon (1978), identifies multivariate outliers. It is a ratio of the determinant of the data matrix with an observation deleted to the determinant of the entire data matrix. Although the AP statistic has been used…

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…

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'…

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…

Explains how computerized game-simulation experiments were conducted to ascertain responses to the 1980 eruptions of Mt. St. Helens (Washington). Results indicate different aspects of individual preferences and family decisions with respect to relocation: (1) highly consistent in the game simulation; (2) responsive to the simulated threat; and (3)…

Describes an ongoing research project designed to develop a computer model capable of simulating the service delivery activities of community mental health care centers and human service agencies. The goal and methodology of the project are described. (NB)

Reports on the current utilization level of computers in postsecondary accounting programs. Findings are taken from a survey of all 228 schools accredited by the American Assembly of Collegiate Schools of Business. (CH)

Allowed undergraduate students (N=70) to interact for 44 minutes with ELIZA, a computer simulation of psychotherapy, and compared their responses during the first and second halves of the session. Results showed a significant increase in responses in roughly half of the categories. (LLL)

In a Monte Carlo analysis of single-subject data, Type I and Type II error rates were compared for various statistical tests of the significance of treatment effects. Data for 5,000 subjects in each of 6 treatment effect size groups were computer simulated, and 2 types of treatment effects were simulated in the dependent variable during…
