Describes an exercise in biometrical genetics based on the noninteractive use of a computer simulation of a wheat hydridization program. Advantages of using the material in this way are also discussed. (Author/JN)

The probabilities of attaining varying magnitudes of standardized effect sizes by chance and when protected by a 0.05 level statistical test were studied. Monte Carlo procedures were used to generate standardized effect sizes in a one-way analysis of variance situation with 2 through 5, 6, 8, and 10 groups with selected sample sizes from 5 to 500.…

When normality does not hold, nonparametric tests represent an important data-analytic alternative to parametric tests. However, the use of nonparametric tests in educational research has been limited by the absence of easily performed tests for complex experimental designs and analyses, such as factorial designs and multiple regression analyses,…

Interactive videodisc makes possible a powerful educational experience in which computer-based educational systems can display video imagery, real-time action, and stereo sound. Interactivity, teaching with videodisc, electronic tutors, videodisc technologies, and costs are among the topics discussed. Use of videodisc for games and simulating…

The Prisoner's Dilemma (PD) game demonstrates how cooperative or competitive choices influence decision making between two people or groups. A study of 48 college students tested an infinite-choice, continuous-time version of the PD. Results indicated that oscillatory cooperation was the predominant over-time behavior, that players matched…

Demonstrates how principles of simulation help students develop working models or prototypes. Explains how computer software enables this process for learners with only basic computer knowledge. (SK)

The consequences of underextracting factors and components within and between the methods of maximum likelihood factor analysis and principal components analysis were examined through computer simulation. The principal components score and the factor score estimate (T. W. Anderson and H. Rubin, 1956) tended to become different with…

Presents a design framework that incorporates integrated structures for modeling knowledge and skills, designing tasks, and extracting and synthesizing evidence. Illustrates these ideas in the context of a project that assesses problem solving in dental hygiene through computer-based simulations. (SLD)

Discusses research in spatial cognition that uses computer-simulated three dimensional environments and evaluates the use of virtual desktop environments by replicating an experiment which was formerly done in a laboratory or real world setting. Investigates the role of landmarks when acquiring route knowledge in a system of paths. (Author/LRW)

Describes advances in and advantages of computer simulation in education and industry. Gives examples from health care and waste handling industries and technology education classrooms. (SK)

Forms a conceptual framework for studying learning in artificial environments, i.e. computer-supported simulations of natural environments. Discusses the ideas that cognition is embodied in physical activity, that this activity is embedded in a learning environment, and that learning is the result of adaptation of the learner to the environment…

Provides a classification scheme for computer simulation, role playing, and educational games. Discusses outcomes of each when applied in business and management education and training. (Contains 52 references.) (SK)

A theory of classical conditioning is presented, which is based on a parallel, rule-based performance system integrated with mechanisms for inductive learning. A major inferential heuristic incorporated into the theory involves "unusualness," which is focused on novel cues. The theory is implemented via computer simulation. (TJH)

A simulation study by B. D. Wright and G. A. Douglas is critiqued, which indicates that the unconditional maximum likelihood method is an appropriate substitute for the theoretically superior conditional method for estimating parameters of the Rasch model. The study appears to rest on inadequate logic. (TJH)

Describes exploratory experiments in evaluating and improving a thesaurus through studying its effect on retrieval. A formula was developed to measure the conceptual distance between queries and documents encoded as sets of thesaurus terms. Comparison to the performance of people judging conceptual distance shows that the formula accurately…
