Described is a project involving the introduction of microcomputers into the laboratory portion of a college general physics course for data collection and analysis. The results of an evaluation of this program are presented. (CW)

Presented are five examples of the application of computer technology to undergraduate chemistry instruction. Topics include: an interface for kinetic experimentation; theoretical calculations; automation of chemical techniques; searching the chemical literature; and Huckel molecular orbitals. (CW)

Presented are two applications of computer technology to chemistry instruction: the use of a spreadsheet program to analyze acid-base titration curves and the use of database software to catalog stockroom inventories. (CW)

Summarizes the capabilities of a computer program related to forest fertilization. Provides a description of input parameters, some sample exercises, software specifications, and availability information. Additional references are listed. (Author/RT)

Discussed is a method of measuring the coefficient of linear expansion of a solid. Getting many data points, using a computer program using the least square fit technique, and modifying the apparatus are described. (YP)

The main part of this project involved using a computer, either an Apple or an IBM, as a chart recorder for the infrared (IR) and nuclear magnetic resonance (NMR) spectrophotometers. The computer "reads" these machines and displays spectra on its monitor. The graphs can then be stored for future reference and manipulation. The program to…

This project involved interfacing of microcomputers with three chemical instruments--Nuclear Magnetic Resonance (NMR), Infrared Spectroscopy (IR), and the spectrophotometer. A Pascal program called "Spectrum" allows data from the NMR to be read and graphed, a specific area of the graph zoomed, ratios of specified areas of the graph…

Described are the uses of a spreadsheet program to compute the free energy change associated with a reaction; to model acid/base equilibria; and to solve equilibrium constant expressions. Stressed are the advantages derived from having the spreadsheet perform the multiple, trivial calculations. (CW)

Described is a laboratory interface system including hardware, software, and student activities. Student use of this system is reviewed stressing experimental design skills and student-designed experiments. (CW)

Presented are five ideas for A-level biology experiments using a laboratory computer interface. Topics investigated include photosynthesis, yeast growth, animal movements, pulse rates, and oxygen consumption and production by organisms. Includes instructions specific to the BBC computer system. (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)

Discussed is a program created to serve as an instructional tool for teaching basin analysis. Described is the use of the program for interpreting plots resulting from backstripping methods. Included in the discussion are implementation, applications and availability of the "Subside!" program. (CW)
