A method for estimating the first eigenvalue of random data correlation matrices is reported, and its precision is demonstrated via comparison to the method of S. J. Allen and R. Hubbard (1986). Data generated in Monte Carlo simulations with 10 sample sizes reaching up to 1,000 were used. (SLD)

The robustness of the likelihood ratio difference statistic to the violation of a regularity condition when used to assess differences in fit provided by pairs of latent class models was investigated. Recommendations are made regarding the use of the statistic under violation of the regularity condition. (SLD)

Discussion of educational software evaluation highlights an evaluation based on program instrumentation of a medical school simulation program. Evaluation strategies are discussed; evaluation techniques, including interviews, questionnaires, and observation are described; and implications of the results of the program instrumentation for the…

Examines the implications of connectionist models of cognition for second-language theory, in which all knowledge is embodied in a network of simple processing units joined by connections that are strengthened or weakened in response to regularities in input patterns. A connectionist framework is proposed within which hypotheses about…

To teach the modern concepts of cavity preparation, it is desirable to have a supply of natural teeth exhibiting suitable carious lesions. This paper describes a simple method for producing consistent artificial lesions in extracted natural teeth. (MLW)

Describes the "Buffon's Needle" problem, which is calculating the probability that a needle will cross one of two separated lines. Calculates the probability when the length of the needle is greater than the space of the two lines. Provides an analytic solution and the results of a computer simulation. (YP)

The application of operations research and computers is providing school bus routing and scheduling to five California counties. Illustrates the system requirements, steps for computerized calculations, a sample bus assignment report, and three data files. (MLF)

The authors describe a simulation program based on a workshop approach designed for postsecondary business students. Features and benefits of the workshop technique are discussed. The authors cover practical aspects of designing and implementing simulation workshops. (CH)

This bibliography contains selected journal articles and documents from the ERIC database which present an overview of current and proposed usage of electronic devices in preservice teacher education, with some analyses of results. (IAH)

Offers various interpretations of global education. Discusses the views of a number of persons in the field on why global education is taught. Suggests that use of simulation and early intervention at the elementary and secondary school level are answers to the question of how to teach global education. (KO)

Achievement test scores from 144 Missouri students were used to assess the instructional effectiveness of a microcomputer simulation in teaching a secondary vocational agriculture course. Microcomputer simulation as a teaching strategy was shown to be as effective as the normal lecture/discussion method. (Author/JOW)

Describes French language class simulation activities, based on life inside a Parisian apartment building, that combine oral and written language practice. (MSE)

Presented is a simulation program for Apple II computer which assays the effects of a series of variables on bacterial growth and interactions between microbial populations. Results of evaluation of the program with students are summarized. (CW)

Presents the LOGO computer language as a source to experience and investigate scientific laws. Discusses aspects and uses of LOGO. Lists two LOGO programs, one to simulate a gravitational field and the other projectile motion. (MVL)

It is proposed that the various aspects of drama and dramatization can be used in the language classroom to bring about a more pragmatic approach to language instruction and provide a better selection of classroom activities. (MSE)
