Examines the circumstances surrounding the demise of mass circulation magazines. System Dynamics methodology is applied to modeling a typical large magazine publishing company and the assumptions built into the model are tested by an empirical study of the old "Saturday Evening Post." (Author/IRT)

This material provides students with information to prepare for a mock trial. The defendant in this case has been accused of the crime of driving under the influence of alcoholic beverages causing severe bodily injury. Case materials include stipulated facts, jury instructions, depositions, and other related materials. (EH)

Discusses application of systems analysis to social and behavioral science as well as machine and non-machine systems. Presents rationale, principles, techniques, and advantages and disadvantages. (CJ)

A relatively simple Gaussian-type diffusion simulation model for calculating urban carbon (CO) concentrations as a function of local meteorology and the distribution of traffic is described. The model can be used in two ways: in the synoptic mode and in the climatological mode. (Author/BL)

Looks at the use of simulations and games as research instruments in education. Examines two applications of simulations as research instruments and a major problem that stands in the way of their use. (Author/DN)

Describes a conceptual scheme that will help elementary school children understand the occupations and types of work he learns about in school. (SB)

Reports a test of the stability of the model used in Jay Forrester's World Dynamics''. When Forrester's fundamentally Malthusian assumptions were replaced by technological-optimist views, computer simulations predicted a stable population with increasing quality of life, rather than a population crash and decreasing quality of life. (AL)

Discusses educational applications of computer simulation and model building for grades K to 8, with emphasis on the usefulness of the computer simulation language, micro-DYNAMO, for programing and understanding the models which help to explain social and natural phenomena. A new textbook for junior-senior high school students is noted. (EAO)

The Simulated Minority Admissions Exercise, an educational technique that simulates a typical medical school admissions situation, is described. The main objective is to help medical schools to select potentially successful minority applicants and to improve their retention by ensuring that they enter medical school under positive circumstances.…

Describes the historical and international development of simulation and gaming in terms of simulation as analytical models, and games as communicative models; and forecasts possible futures of simulation and gaming. (CMV)

The development of anasynthesis--the process of analysis, synthesis, modeling, and simulation--as applied to decision making and problem solving in education and training is explored, and its future with regard to education is discussed. (RAO)

Describes a computer simulation model developed to provide information on the number of terminals or readers needed in the advent of microfilm or computerized catalogs in libraries. Systems with two to 14 terminals are simulated, and decision variables include average patron waiting time, number of patrons lost, and average terminal utilization.…

Defines and demonstrates a framework for studying differential item functioning and differential test functioning for tests that are intended to be multidimensional. The procedure, which is illustrated with simulated data, is an extension of the unidimensional differential functioning of items and tests approach (N. Raju, W. van der Linden, and P.…
