The cross-validated classification accuracies of three predictor weighting strategies (least squares, ridge regression, and reduced rank) were compared under varying simulated data conditions for the two-group classification problem. Results were somewhat similar to previous findings with multiple regression when absolute rather than relative…

Describes the development of two interactive computer simulations which were fully integrated with other course materials. The simulations illustrate the effects of various real and monetary "demand shocks" on aggregate income, interest rates, and components of spending and economic output. Includes an evaluation of the simulations'…

Examined how successfully an environmental simulation technique could provide older people with a working knowledge of an unknown building. Compared three groups of participants: site visit (n=20); simulation (n=20); and control (n=20). Found simulation comparable to site visits in instilling confidence in way-finding ability, providing a mental…

This study examined how six experienced teachers got information about students' knowledge and used that information to adjust their instruction while tutoring the students in addition. Each teacher tutored five simulated students and one live student. (RB)

Computer sampling from a multivariate normal spherical population was used to evaluate Type I error rates for a test of P = I based on Fisher's tanh(sup minus 1) variance stabilizing transformation of the correlation coefficient. (Author/TJH)

Describes a role-playing activity designed to show how the United States began its involvement in Vietnam. Provides sample handouts assigning students to support either the French or Vietnamese side of a debate. The teacher assumes the role of President Truman who must decide which side will receive U.S. support. (GEA)

Reviews "The U.S. Constitution Then and Now," a two-unit program using the integrated database and word processing capabilities of AppleWorks. For grades 7-12, the units simulate the constitutional convention and the principles of free speech and privacy. Concludes that with adequate time, the program can provide a potentially powerful…

Results of the two surveys (combined n = 145) show that historians are using computers for word processing, research, and teaching support. Only a third of the respondents indicated they were using computers in the classroom, however. The most frequently reported classroom uses were student projects, simulations, and tutorials. (JDH)

Two activities are described which simulate for educators, papraprofessionals, parents, and students, learning problems encountered by students with special educational needs. The activities, modifications of Simon Says and Around the World, emphasize auditory processing skills and mental mathematical computations. (CL)

Favorably reviews "The Other Side," a global conflict resolution simulation available for high school social studies classes. Maintains that this program is well worth the time and effort required to integrate it into the study of modern history and international relations. (JDH)

Describes a scheme for the mechanization of fixed-wing, lateral/directional dynamics as demonstrated on the EAI 580 analog/hybrid system. A review of the complete six degrees of freedom program is included, along with useful guidelines of aircraft simulation in the engineering laboratory. (Author/JN)

The ANDS (A Natural Deduction System) model, described in this article, is a psychological theory of propositional reasoning that makes explicit assumptions about memory and control in deduction. A computer simulation of the ANDS model yields proofs similar to those of untrained subjects. (Author/BW)

Four groups of 18 adult listeners rated the tape-recorded cries of low- and high-risk infants on four Likert-type scale items. Results indicate that within-group methods of cry presentation accentuate the perceptual distance among cry types and may actually create many reliable differences that would not be found in between-group comparisons.…

The article examines computers in the learning processes, noting applications in drill and practice, remediation, tutorial programs, testing, and simulation. A summary of computer use with children having communicative disorders concludes the article. (CL)

Adventure/fantasy games, a form of simulation software, are described and recommended for bright but unmotivated learning disabled students. Several commercial games are reviewed and suggestions are given for writing the program for an adventure game. The games are thought to contribute to reading comprehenson, spelling, critical thinking, and…
