Describes an educational project linking classrooms using telecommunications with a four-person bicycling team exploring Mayan ruins in Central America. Provides a historical overview of the Mayan civilization. Includes suggested activities and provides information on how to obtain lesson plans on the project. (CFR)

Because density is unobservable and must be inferred from knowledge about weight and size, it is a difficult concept to teach and learn. Even after traditional instruction, many students still have an undifferentiated concept that mixes characteristics of both weight and density. In this study, researchers tested the effectiveness of a unit they…

Computer simulations of agricultural finance and management may be helpful to students preparing for agricultural careers. Simulations would provide problem definition and problem solving in realistic interactions with complex and ambiguous situations similar to those encountered in farming. The paper describes a major financial problem for…

Discusses the need for education about soil erosion and advocates the use of the Universal Soil Loss Equation (USLE) to show the impacts of human and natural action on the land. Describes the use of a computer simulated version of the USLE in several environmental and farming situations. (TW)

Contains seven articles about computer applications to chemistry instruction. Includes descriptions of a three-dimensional animation of a potential energy surface, numerical solutions of kinetic equations, applications for spectroscopy courses, a computer-controlled experiment on the tin/lead solid/liquid phase diagram, an inexpensive thermistor…

Discussion of microcomputer use in public elementary schools focuses on the field of special education. Two main ways of using computers are described: (1) traditional uses, including administration, computer-assisted instruction, and assessment; and (2) new applications, including programming, word processing, simulations, and prosthetic aids…

Describes the development of a computer simulation model of forage-beef production systems, which is intended to incorporate soil, forage, and animal decisions into an enterprise scenario. Produces a summary of forage production and livestock needs. Cites positive assessment of the program's value by participants in inservice training workshops.…

Describes an open-ended computer simulation project that can be used to illustrate the growth of solid crystals in different forms at any level from high school physics to graduate physics. Discusses a simple computer program in BASIC language on an IBM personal computer. Gives examples of simulations. (CW)

Presented is a detailed review of eight computer software packages. Strengths, weaknesses, and recommendations for each game are listed. Mathematical and thinking skills, problem solving, drill and practice, procedural activities, decision making, understanding money, and basic skills are emphasized. (KR)

(MVL)

Presents a geography program to show students why the European Community was formed. Involves student research of economic data, creation of a computer database on the European Community, and simulation of trading. Emphasizes geographic themes of movement, region formation, and change in response to economic forces. Includes game rules, sample…

Described is the evolution of a multimedia approach for teaching Computer Aided Design (CAD). The presentation includes video tapes, a computer, an overhead camera, and hard-copy handouts containing class notes and CAD assignments. Also described is a complete "on-demand" training system for future use. (KR)
