Discusses the mathematical model presented by Vito Volterra to describe the dynamics of population density. Discusses the predator prey relationship, presents an computer simulated model from marine life involving sharks and mackerels, and discusses ecological chaos. (MDH)

Described is a project where students gain experience in handling large volumes of hazardous materials, process start up and shut down, equipment failures, operational variations, scaling up, equipment cleaning, and run-time scheduling while working in a modern pilot plant. Included are the system design, experimental procedures, and results. (KR)

Six case studies were conducted on the use of business games and simulations in higher education. Results showed that cognitive learning was greatly affected by particular approaches of students; competitiveness tends to have a negative effect on cognitive gains; and learning is enhanced by advance briefing and tutor involvement during the game.…

Describes an activity in which students investigate the effects of selected natural and synthetic substances on the rate of apple browning. Includes background information for the teacher, a list of necessary materials, and student instructions. (KR)

Presents a method for simulating the behavior and perceptual deficits demonstrated by patients who have undergone the split brain surgical procedure. Presents several activities in which two volunteers are required to accomplish certain tasks as one person. Suggests that these activities show how split brain patients illustrate certain lateralized…

Discussion of communication between designers and users of information systems focuses on a review of seven participatory design techniques in terms of the communication dimensions found in the Lievrouw and Finn communication systems model. Implications for the development of more effective and appropriate design models and methods are suggested.…

Provides background information as an introduction to three articles on command and control simulations that involve police and fire departments. Elements of command and control situations are discussed, including leadership, management of people and resources, communication, and coordination; the effectiveness of simulations is considered; and…

Describes the development of a low-cost desktop simulator for basic training of train drivers that is being tested by British Rail. The use and advantages of digital video interactive (DVI) technology are explained, limitations of videodisks are noted, the design of the simulator is described, and future developments are considered. (LRW)

Discusses the value of educational simulation in enhancing teaching. It is effective because it is a realistic, active learning experience, it is highly interpersonal, there is an element of play, and it demands that participants think of ideas and implement strategies and solutions. (SM)

Describes projects at the University of Central Florida to test new training technologies under controlled but realistic settings. Original plans for an "Experimental Prototyping Classroom" are discussed; and current developments in language training research, gaming technology, and virtual environments are described. (EAM)

This article describes "Thinking Actively in a Social Context," a multiphase model to assist in the development of problem-solving courses based on student needs and experiences. An example of such an interdisciplinary course (simulating a new settlement on another planet) for high ability children in grades five, six, and seven is detailed. (DB)

This article examines the concept of interactivity and discusses human-to-human interactivity versus computer-to-human interaction in education. Levels of communicative interdependence are explained, variables that are important ingredients of interactivity are discussed, learner control is discussed, and two interactive instructional systems are…

A method is proposed for sequential evaluation of reliability of psychometric instruments. Sample size is unfixed; a test statistic is computed after each person is sampled and a decision is made in each stage of the sampling process. Results from a series of Monte-Carlo experiments establish the method's efficiency. (SLD)

Four mentally retarded adults received single case instruction, followed by general case instruction, on washing machine and dryer use, using either actual appliances or simulation. Generalization errors were affected by single/general case instruction, not by use of simulated versus natural conditions. General case simulation was more efficient…

Considers three main components of self-directed learning: (1) topic knowledge; (2) procedural skills; and (3) self-monitoring. The role of computer-assisted instruction in autonomous learning is discussed, software that fosters independent problem solving is reviewed, and it is recommended that computers be incorporated in courses emphasizing…
