The number of experimentally derived structures of cellular components is rapidly expanding, and this phenomenon is accompanied by the development of a new semiotic system for teaching. The infographic approach is shifting from a schematic toward a more realistic representation of cellular components. By realistic we mean artist-prepared or…

Describes interactive, geology programs (GEOPACK) for use in geostatistical applications, demonstrations and reviews, and geocartography. Programs, designed for beginning and advanced students, make use of the graphics capabilities of the Apple II microcomputer. (JN)

Describes an interactive computer program designed to provide graphical representations of chemistry and engineering experimental data sets and results of data analyses. Extremely flexible, the program requires no reprograming when new models are used. Models are entered into the program as input lines. (JN)

Describes a presentation of basic quantum mechanics for nonscience majors that relies on a computer-generated graphic display to circumvent the usual mathematical difficulties. It allows a detailed treatment of free-particle motion in a wave picture. (MLH)

Describes the use of computer-assisted graphical displays in experiments to determine the order and activation energy for a chemical reaction. (MLH)

Discusses use of two EAI semi-expanded TR-20 units to display solutions to differential equations for harmonic oscillators, quantum-mechanical particles, trajectories, radioactive decay series, and hysteresis curves. Suggests practical applications for both undergraduate physics laboratories and classroom demonstrations. (CC)

Describes a method to produce 35mm color slides directly from the display screen of a computer terminal using techniques and equipment available to most teachers and researchers. Discusses the hardware and software needed, procedures, some of the problems encountered, and the potential uses of this method. (CW)

Investigated the overall effectiveness of and use of animation/graphics in "Introduction to Organic Chemistry" computer programs on student achievement and attitudes (n=approximately 400). Results indicate that although materials were effective animation sequences, they did not have an effect on student test scores. (JN)

Described is a computer program which accepts face data, performs all necessary symmetry operations, and produces a drawing of the resulting crystal. The program shortens computing time to make it suitable for online teaching use or for use in small computers. (Author/DC)

Two copy-protected chemistry simulations (for Apple II) are described. The first demonstrates Hess' law of heat reaction. The second illustrates how heat of vaporization can be used to determine an unknown liquid and shows how to find thermodynamic parameters in an equilibrium reaction. Both are self-instructing and use high-resolution graphics.…

These materials were designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process. The report describes design standards for the computer programs. They are designed to be…

These materials were designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process. PRNT3D is a subroutine package which generates a variety of printed plot displays. The displays…

Discusses chaotic behavior (movement) in a nonlinear system using LOGO programs. Presents several examples with program listings. (MVL)

Considers the development of a computer program for interactive, screen-oriented problem solving. Provides theoretical background and program development to determine internal energy, heat capacity, and entropy. Lists the program written in BASIC for Apple II computers. (MVL)

Notes two uses of computer spreadsheets in the chemistry classroom. Discusses the general use of the spreadsheet to easily provide changing parameters of equations and then replotting the results on the screen. Presents a molecular orbital spreadsheet calculation of the LCAO-MO approach. Supplies representative printouts and graphs. (MVL)
