Effects of microcomputer-based laboratory (MBL) exercises and level of cognitive development on high school biology students' ability to construct and interpret line graphs were investigated. Forty-six students enrolled in general biology classes at a rural high school volunteered to participate in the study. These students were administered…

Describes a computer-assisted oil exploration and production game for students involved in a short course in petroleum geology. Outlines the game and its procedures, and provides sample structure maps generated by the computer in the course of playing the game. (TW)

Describes a microcomputer program that simulates the pattern of evolution and produces clade diagrams and summary statistics. Allows users to vary the odds affecting the fate of a species. (TW)

Discusses some of the attributes of effective tutorial software programs. Describes four science programs that focus on the physical and earth sciences, and highlights some of their features that are proposed as features of high-quality educational software. (TW)

Explores several concepts in computer assisted design/computer assisted manufacturing (CAD/CAM). Defines, evaluates, reviews and compares advanced computer-aided geometric modeling and analysis techniques. Presents the results of a survey to establish the capabilities of minicomputer based-systems with the CAD/CAM packages evaluated. (CW)

Presents current trends in the development of expert systems within the Department of the Navy, particularly research into expert graphics systems intended to support the Authoring Instructional Methods (AIM) research project. Defines artificial intelligence and expert systems. Discusses the operations and functions of the Navy's intelligent…

Describes 10 computer programs (available from authors), including graphics display of molecular structure, cyclohexane stereo chemistry, calculation of thermodynamics properties of chemical reactions, and others. Also described graphical display of chemical interactive programs using a programmable calculator and discusses distribution of…

Tested were all-verbal or verbal-pictorial presentations followed by either pictorial practice or a control task with 96 undergraduates; results favored pictorial presentation with review. Also tested were effectiveness of pictorial review tasks to a read-twice control with 50 different undergraduates. Pictorial review facilitated performance and…

Reviewed are four computer software packages: "Minerals Data Base"; "Canvas 2.1," a graphics program for producing technical illustrations; "Glossary of Geology Speller"; and "PCUSA," which produces maps and statistical diagrams of the United States. Hardware requirements, functions, cost and availability…

Describes the use of a supercomputer in chemistry and physics instruction. The computer is used by high school students to create high quality, nearly 3-D graphic images of scientific phenomena. (PR)

At some point in their education, pre-engineering students will take physics and/or calculus. For many freshmen who aren't certain about their career paths, taking these courses is a litmus test to determine whether they have the aptitude or desire to pursue an engineering degree. Therein lies the challenge for many students in the U.S. Science,…

Developed as an introduction to computer programming using an Apple microcomputer, this document presents teachers and students with: (1) essential vocabulary used in the BASIC language; (2) syntax; and (3) programming techniques. Simple hands-on activities designed to guide the learner through beginning BASIC programming skills and fundamental…

Turtle graphics is a popular vehicle for introducing children to computer programming. Children combine simple graphic commands to get a display screen cursor (called a turtle) to draw designs on the screen. The purpose of this study was to examine young children's abilities to function in a simple computer programming environment. Four- and…

Introduced is a unique generation method of Fourier series requiring simple mathematical skills and using computer programs. Discusses Fourier synthesis by microcomputer, and Fourier analysis with simple equipment. Shown are a circuit diagram, computer programs, monitor displays and tables of data. (YP)

Presents a computer program which prints out a calendar corresponding to any year A.D. and states the objectives for such a program. Shows an example of a sample run. (RT)
