This paper provides examples of Aid-to-Thought uses in urban decision making, classroom laboratory planning, and in a ship antiaircraft defense system. Aid-to-Thought modeling and simulations are tools students can use effectively in a STEM classroom while meeting Standards for Technological Literacy Benchmarks O and R. These projects prepare…

Learning embryology remains difficult, since it requires understanding of many complex phenomena. The temporal evolution of developmental events has classically been illustrated using cartoons, which create difficulty in linking spatial and temporal aspects, such correlation being the keystone of descriptive embryology. We synthesized the…

A PASCAL graphics and instrument interface program for a Z80/S-100 based microcomputer was developed. The computer interfaces to a stopped-flow spectrophotometer replacing a storage oscilloscope and polaroid camera. Applications of this system are discussed, indicating that graphics and analog-to-digital boards have transformed the computer into…

Describes an experimental setup using a microcomputer for demonstrating the circadian movement of petioles. Discusses experiments that were performed using this apparatus and factors that relate to these plant movements. Includes graphs that have been obtained. (CW)

Because advanced students had difficulty in interpreting cleavage patterns obtained by gel electrophoresis related to rapid sequencing techniques for DNA and RNA, several formats were developed to aid in understanding this topic. Formats included print, print plus scrambled print, interactive computer-based instruction, and high-resolution…

Discusses the nature of a nuclear magnetic resonance (NMR) experiment, the techniques used, the types of structural and dynamic information obtained, and how one can view and refine structures using computer graphics techniques in combination with NMR data. Provides several spectra and a computer graphics image from B-form DNA. (MVL)

Demonstrations, procedures, games, teaching suggestions and information on a variety of physics topics are presented, including hydraulic rams, units and formulae, static electric motors, a computer graphics program, diffraction, adaptation of a basic meter, photoelasticity, photo-diodes, radioactive decay, and analog-digital conversions. (DC)

Discussed are seven computer programs: (1) a computer graphics experiment for organic chemistry laboratory; (2) a gel filtration simulation; (3) judging spelling correctness; (4) interfacing the TLC548 ADC; (5) a digitizing circuit for the Apple II game port; (6) a chemical information base; and (7) an IBM PC article database.

The Technology Edu-Camp described in this report was held in July of 1988 at Arkansas State Technical Institute. Purposes were: to provide vocational instructors an opportunity to expand their knowledge and understanding of the needs of technical occupations; to upgrade their technical skills; and to develop lesson materials for courses in…
