The nature of qualitative understanding and associated learning processes in the context of a computer simulation called the "Envisioning Machine" (EM) are investigated. The questions focused on in this paper include the following: What sorts of knowledge do students' construct? What role does prior knowledge play in the construction of…

Explains the computer-based modeling "language" of Structural Thinking and Experiential Learning Laboratory with Animation (STELLA) and its applications to environmental education. Describes STELLA's interactive capabilities through an example of a program on predator-prey interactions. Recommends the use of STELLA for clarification of…

Argues that computer-simulated experiments offer educational tools to foster student development of problem-solving skills without traditional laboratory time and expense. The evolution of the medical physiology course at Rush Medical College is used to illustrate trends in this area. They include experiments on PLATO, and on personal computers.…

Discusses the nature of misconceptions in science and the role of teachers and students in correcting these misconceptions. Also describes a simulation program that centers on some basic topics in Newtonian mechanics, outlining its structure and examining some of the premises that served as guidelines in its design. (JN)

An interactive computer program in microbial genetics is described. The simulation allows students to work at their own pace and develop understanding of microbial techniques as they choose donor bacterial strains, specify selective media, and interact with demonstration experiments. Sample questions and outputs are included. (DH)

Describes a computer simulation program which helps students learn the main biochemical tests and profiles for identifying medically important bacteria. Also discusses the advantages and applications of this type of approach. (ML)

Describes and lists a program for Apple Pascal Version 1.1 which investigates the behavior of the bicarbonate-carbon dioxide buffer system in acid-base disorders. Designed specifically for the preclinical medical student, the program has proven easy to use and enables students to use blood gas parameters to arrive at diagnoses. (DH)

Seven possible applications of microcomputers in high school science programs are discussed. They include computers as calculators, computers as black-box number crunchers, computers for teaching computer literacy, computers as blackboards, computer-assisted instruction, computer simulations, and process control. (JN)

Describes a computer-based Wilderness Travel Simulation Model that reduces the complexity of the outdoor system under study, allows students to act as managers (devising and testing their own management strategies), and increases student exposure to characteristics of actual park and wilderness areas. Two scenarios of recreational use patterns are…

Faced with beginning the school year without the necessary chemicals for experiments in a newly adopted chemistry textbook, a department chairperson conceived the idea of supplementing the textbook with simulated experiments on microcomputers. The methodology used to select the appropriate software is described, with suggestions for some new…

Describes the use and impact of process design simulators in process design courses. Discusses topics covered, texts used, computer design simulations, and how they are integrated into the process survey course as well as in plant design projects. (JM)

The educational design of a project option in an Open University course on evolution is described. Also described is the simulation which models the genetic and evolutionary consequences of two populations of a species of flowering plant coming together after a period of genetic isolation. (Author/JN)

Reports on the findings of a study designed to develop three-dimensional virtual reality technology (VRT) learning programs for middle school students and evaluate the program's educational value. Focuses on the topic of structure and function of the eye. Concludes that VRT simulations allow comfortable interaction with computers and increase the…

A mechanical analogy between the microscopic motion of a charged carrier in an ordinary resistor and the macroscopic motion of a ball falling along a slanted board covered with a lattice of nails is introduced. The Drude model is also introduced to include the case of inelastic collisions. Computer simulation of the motion is described. (KR)

Described is the author's decision to help a student find alternatives to performing several terminal experiments on animals in a college physiology class. Replacement exercises used for studying the properties of muscle types are described. Details about the difficulties and successes of the entire experience are reported. (KR)
