Data from two samples of 32,862 and 6,757 males, respectively, from the Danish draft board indicate that gains in intelligence test scores are continuing and are concentrated among lower intelligence levels. Monte Carlo simulations suggested that this distributional change did not result from a ceiling effect in the test. (SLD)

Discusses the "Exercise in Hard Choices," a simulation published by the Committee for a Responsible Federal Budget (CRFB), that requires students to make decisions on some of the most significant and controversial budget options facing the U.S. Congress and president. Reports on the simulation's classroom success, stating that it…

A classroom exercise is described that simulates the everyday interactions within a French apartment house. The cultural, linguistic, and affective benefits of the activity are discussed. (MSE)

Classroom simulation of a hotel is proposed as a motivating method for functional language learning. Related activities and exercises are outlined. (MSE)

Discusses a laboratory exercise simulating the paths of light rays through spherical water drops by applying principles of ray optics and geometry. Describes four parts: determining the output angles, computer simulation, explorations, model testing, and solutions. Provides a computer program and some diagrams. (YP)

Describes a class activity demonstrating the reality of revolution to introductory political science students. Student "plants" rebel against a teacher's "injustice," overthrow the teacher when he calls on a higher authority, and mobilize the class to sign a petition. Follow-up discussion covers elements required for revolution. (LS)

Presents a world climate simulation game in which students demonstrate knowledge of the Koppen System of Climate Classification, ability to read and interpret a climograph, and ability to locate places by means of longitude and latitude coordinates in an effort to locate a ring of spies who have planted a bomb in an unidentified city. Clues and…

Focuses upon classroom presentation of issues related to the Fourth Amendment of U.S. Constitution. Presents a description of a drug test case simulation (D. Hess); a case involving drug testing in the public sector which is to be heard by the Supreme Court (L. Mandell); and other teaching strategies (D. Hess). Provides a guide for finding Supreme…

In applying I. I. Bejar's method for detecting the dimensionality of achievement tests, researchers should be cautious in interpreting the slope of the principal axis. Other information from the data is needed in conjunction with Bejar's method of addressing item dimensionality. (SLD)

A method of assessing rater reliability via a design of overlapping rater teams is presented. Covariances or correlations of ratings can be analyzed with LISREL models. Models in which the rater reliabilities are congeneric, tau-equivalent, or parallel can be tested. Two examples based on essay ratings are presented. (TJH)

A study assessed the effects of three teaching strategies that incorporated a microcomputer component: (1) tutorial, (2) drill and practice, and (3) simulation. Each strategy was compared with one another and with the traditional lecture/discussion method. Student achievement and attitudes were essentially equal in all four methods. (JOW)

Hearing-impaired high school students created a simulated world where sign language was the dominant mode of communication, and role-played such careers as doctors, bankers, and police officers. Hearing students were invited to visit this simulated world and found how inaccessible various facilities and services were to people without sign…

The stability of psychometric "g," the general factor of intelligence, is investigated in simulated correlation matrices and in typical empirical data from a large battery of mental tests. "G" is robust and almost invariant across methods of analysis. A reasonable strategy for estimating "g" is suggested. (SLD)

Recounts personal experiences in the design of simulations/gaming for city development and planning. Notes early games and describes the development of three land use and city growth games. Discusses revisions, conference demonstrations of the games, and collaborative efforts. (AEF)

Analyzes shortcomings of computer monitors, including one-way communication and organization of the monitor display, when they are used with multimedia in open learning environments. Solutions are described according to the concepts and theories developed by Min, Koopal, Gritter, Struyker, Boudier, Coleman, Miltenburg, and Van Schaick Zillesen…
