Describes simulation software that was used with an LCD overhead display and laptop computers for large introductory psychology courses. The use of experiment simulators to increase student interest and activity is discussed, hardware is explained, and interaction between students, instructor, and the simulation is described.

Three correlation matrices (PEARSON, POLYCHORIC, and TOBIT) were used to obtain reliability estimates on ordered polytomous variable models. A Monte Carlo study with different levels of variable asymmetry and 400 sample correlation matrices demonstrated that the PEARSON matrix did not perform as well as did the other 2 matrices. (SLD)

A study using simulated doctor-patient interactions found that social work students inappropriately attributed both positive and negative characteristics to patients, apparently on the basis of sociocultural stereotypes. It is suggested that social work educators must address values and stereotyping in clinical assessment training. (MSE)

Compares retention of popular science material by fifth grade students using either computer simulation software or expository text as the instructional tool. Finds a statistically significant superiority in favor of the expository text group. (RS)

Describes projects developed through the Long Distance Learning Network (LDLN) that experimented with using telecommunications in classrooms in the United States and in other countries. A creative writing project involving elementary school students in the United States, Canada, and Australia is described, and a seventh-grade geography project is…

Offers a simulation in which middle school students examine the constitutionality of a creche being placed on town property. Develops an understanding of (1) the religion clauses of the First Amendment, (2) governmental limitations on religious practices, and (3) governmental regulations that may incidentally support religious beliefs. (LS)

Uses recent freedom of expression cases to explore the effect of public opinion and pressure on U.S. Supreme Court rulings, through a simulation for secondary students. Students are assigned a pressure group to represent, discuss the facts in small groups, and formulate their decisions and arguments for class discussion. (LS)

Discusses the use of the mathematics classroom for discovering the relationship among computers, mathematics, and real-world problems. Provides three probability problems and compares the results of three methods, actual trial, computer simulation, and mathematical solution. (YP)

A probabilistic item response theory (IRT) model is developed for pair-comparison design in which the unfolding principle governing the choice process uses a discriminant process analogous to Thurstone's Law of Comparative Judgment. A simulation study demonstrates the feasibility of estimation, and two examples illustrate the implications for…

Presented are suggestions for simulations for students in grades 3-12, designed to promote an understanding of how individuals with handicaps cope and adapt to their disability. Simulation ideas include toothbrushing while blindfolded and dressing with socks covering the hands. A participant's reaction form and an observer's reaction form are…

Shows that graphs can reveal much about feedback systems that formula conceal, especially as microcomputers can provide complex graphs presented as animations and allow students to interact easily with them. Describes feedback systems, evolution of the system, and phase diagram. (YP)

Explains a computer simulation on post-revolutionary Russia in which students must make decisions in order to retain power and improve the economy. Decision areas include improving agricultural productivity, increasing industrial productivity, and establishing the production of consumer goods. (LS)

A procedure--based on item response theory--for testing the hypothesis of unidimensionality of the latent space is proposed. Use of the procedure is supported by an asymptotic theory and a Monte Carlo simulation study. The procedure tests for unidimensionality in test construction and/or compares two tests. (SLD)

Illustrates some of the practical issues and problems connected with the design and use of computerized business games by describing three games which have been developed and operated by staff at Leeds Polytechnic Department of Business Management (United Kingdom). Sample input and output forms are included. (nine references) (LRW)

Describes a simulation exercise that integrates current events with the basics of decision making under crisis. Reports positive results in terms of student participation, interaction and reflection while creating minimal demands on class time. Provides details for using the simulation. (KO)
