Describes direct and indirect voltage input techniques and their applications to voltage measurements with a microcomputer. Details circuitry that can be used for this with a gameport. Gives examples of circuit modifications, application of voltage measurement, and alternatives to this method. (CW)

Presents the results of statistical analyses and interpretations of data obtained from students in two engineering fundamentals courses on an attitudinal survey. Indicates positive and significant improvement in student attitudes toward their own drawing abilities and the importance of drawing in their lives and careers. (CW)

Describes five computer software packages; four for MS-DOS Systems and one for Apple II. Included are SPEC20, an interactive simulation of a Bausch and Lomb Spectronic-20; a database for laboratory chemicals and programs for visualizing Boltzmann-like distributions, orbital plot for the hydrogen atom and molecular orbital theory. (CW)

Describes a computer program written in Microsoft BASIC for use on personal computers to calculate travel times of refracted waves in layered structures with arbitrary dipping interfaces. Exercises for student use are given to illustrate some of the basic properties of reversed refraction travel time graphs. (TW)

Describes how the graphics capabilities of the Apple Macintosh computer can be used in geological teaching by customizing fill patterns with lithologic symbols. Presents two methods for doing this: creating a dummy document, or by changing the pattern resource resident in the operating system. Special symbols can also replace fonts. (TW)

Describes the implementation of a trajectory-plotting program for a microcomputer; shows how it may be used to demonstrate the focusing effect of a simple electrostatic lens. The computer program is listed and diagrams are included that show comparisons of trajectories of negative charges in the vicinity of positive charges. (TW)

Presents examples of didactic computer software developed in a college of engineering, along with a discussion of pedagogical and systems considerations. Discusses the use of the computer in relation to Bloom's Taxonomy. Describes the system approach, which is used to sequentially develop valid and relevant software. (TW)

Eighteen high school biology teachers from a stratified sample of 13 distinct geographical United States regions participated in evaluation of the first year prototypes of Exploring Life, a biology program that includes a textbook with an accompanying Internet component and wet-lab investigations. Web activities explain and reinforce the text and…

This paper reports on the results of substituting one-hour active-engagement tutorials using microcomputer based laboratory (MBL) equipment for traditional problem-solving recitations in introductory calculus-based mechanics classes for engineering students at the University of Maryland. The results of two specific tutorials--one on the concept of…

Computers, because of their computational speed and multi-representational capabilities, are particularly well-suited to the implementation of dynamic models. This paper reviews research conducted on the use of computer-based models in precollege science classrooms. Topics addressed include Investigations of Running Simulations, Investigations of…

Distance education is growing rapidly in response to developments in technology and changes in the world culture and economy. This article reviews how the University of Wisconsin-Madison uses distance education to provide technical information and training to engineers. It also explores potential new directions for providing education and…

Presented are 10 intervention techniques for making science a hands-on experience for disabled students. Included are field trips, lab buddies, flexible rooms, customized lab equipment, lesson adaptation, precourse interviews, involving the class, computer-assisted learning, social considerations, and the team approach. (KR)

Outlined is a specific computer application which can be used to analyze data on plant community composition from the point quarter sampling method. Procedures, examples of spreadsheets prepared in this manner, and evaluation of the activity are presented. (CW)

A collection of Molecular Orbital (MO) programs that have been integrated into routines and programs to illustrate MO theory are presented. Included are discussions of Computer Aided Composition of Atomic Orbitals (CACAO) and Walsh diagrams. (CW)

Reviewed are six computer programs which may be useful in teaching college level chemistry. Topics include dynamic data storage in FORTRAN, "KC?DISCOVERER," pH of acids and bases, calculating percent boundary surfaces for orbitals, and laboratory interfacing with PT Nomograph for the Macintosh. (CW)
