A Monte Carlo experiment was used to evaluate four procedures for estimating the population squared cross-validity of a sample least squares regression equation. One estimator was particularly recommended. (Author/BH)

Reviews recent progress in modeling human cognition, in particular the use of computers in generating models. Topics covered include the information processing approach to cognition, problem solving, semantic memory, pattern induction, and learning and cognitive development. A 164-item reference list is attached. (JL)

Defines six modes of simulation that have been used in science teaching and learning. Discusses the implications of using simulations in the science classroom. (CS)

College students who took the Defining Issues Test (DIT) were instructed to simulate the responses of 11-, 15-, and 19-year-old adolescents; other college students selected moral issues which they believed should be presented to adolescents in those age groups who were faced with the moral dilemmas in the DIT. (Author/DB)

A new model is proposed for explaining children's performance on Pascual-Leone's test of M-space. The new model is used to generate theoretical performance curves for children at four different age levels and seven different levels of stimulus complexity, and it is a viable alternative. Differences between the models are reviewed. (Author/RD)

Described is an environmental awareness simulation game involving the life function of food getting. Instructions, charts, task sheets and questions are included for each segment of the game. (DS)

Presents a teaching simulation which was designed to stimulate the interest of students in a college level political science course (American government). The simulation transforms a class into the Confederal Congress and is designed to increase the students' information retention and bargaining abilities. Pre- and posttesting is discussed.…

The article describes one aspect of an undergraduate college course entitled "Special Education 253: Physically Handicapped" in which students could elect to confine themselves to a wheelchair for 24 waking hours for 20 percent of their final grade. The reactions of the 87 students who participated demonstrate the usefulness of the experience.…

A program in cardiopulmonary resuscitation (CPR) instruction for Florida's school children is described. Program guidelines and support services are detailed for other schools wishing to implement such a program. (JN)

A 60-minute, color videotape of a simulated adult physical examination was produced and used by the University of Pittsburgh School of Pharmacy to introduce clinical clerkship students to the procedures involved in the physical examination. The videotape was evaluated by a 25-question pretest and posttest. (Author/MLW)

Presents a mechanical model for an ecology laboratory that introduces the concept of optimal foraging theory. Describes the physical model which includes a board studded with protruding machine bolts that simulate prey, and blindfolded students who simulate either generalist or specialist predator types. Discusses the theoretical model and data…

Describes a college-level psychology course based on using simulation techniques to teach graduate students about child development. Topics discussed include course description, objectives, activities, evaluation methods, and a discussion of the advantages and disadvantages of the simulation approach. (Author/DB)

To determine if empirically derived dependent variables could differentiate typical conflict and accord discussions, couples engaged in conflict and accord discussions on topics rated prior to and following discussions. Discriminators were volume, criticism, disagreement and sarcasm. Variables which did not differentaite topics were swearing, rate…

Describes a simulation model that examines the relationship of dropout behavior and re-entry flows in a local school system to changes in local socioeconomic factors, school-related conditions, and aspects of labor market participation. Assesses the policy implications for affecting these flows at the local board level. (Author/IRT)
