A series of Microsoft Excel spreadsheets were developed to simulate the process of separation optimization under isocratic and simple gradient conditions. The optimization procedure is performed in a stepwise fashion using simple macros for an automatic application of this approach. The proposed optimization approach involves modeling of the peak…

SCILAB is a lesser-known program (than MATLAB) for numeric simulations and has the advantage of being free software. A challenging software-based activity to analyze the most common linear reversible inhibition types with SCILAB is described. Students establish typical values for the concentration of enzyme, substrate, and inhibitor to simulate…

Described is the development of graphic materials for teaching fundamental concepts in chemistry. Computer simulation provides data and visual materials to aid understanding. (RH)

Described are two computer problems used to provide graphic displays of data in undergraduate chemistry classes. (RH)

The design and use of an instrument simulator is described. Used for student laboratory experiments illustrating the use of mini-computers, it can provide, at very low cost, a repetitive, repeatable output to duplicate the readout of various instruments such as electrochemical experiments, mass spectrometers, pulsed magnetic experiments,…

Describes seven computer simulations of laboratory experiments that allow students to direct experiments, make observations, and record data. (MLH)

Discusses the use of the System Dynamics technique in simulating a chemical reaction for kinetic analysis. Also discusses the use of simulation modelling in biology, ecology, and the social sciences, where experimentation may be impractical or impossible. (MLH)

Describes a computerized experiment in which the student determines the pk of an acid-base indicator from absorption spectra of the indicator at various concentrations. (MLH)

Using the computer, students perform chemical analysis in a medical diagnosis class. (CP)

Techniques for digitalizing analog signal data are presented and compared. The techniques presented are: boxcar averaging, ensemble averaging, unweighted digital filter, weighted digital filter, and analog filter. (BB)

Describes a computer simulation experiment in which physical chemistry students can determine all of the kinetic parameters of a reaction, such as order of the reaction with respect to each reagent, forward and reverse rate constants for the overall reaction, and forward and reverse activation energies. (MLH)

Discusses educational programs carried out by a minimum system which consists of a PDP-8/L computer with 4K memory and an ASR-33 teletype. Indicates that an entire curriculum with 450 students can be handled by simply adding some components. (CC)

Describes the use of a simulation lesson which is written in TUTOR language for the PLATO computer for the purpose of separating a mixture of four ions with known identity. Indicates that students have more freedom to experiment than in laboratories in other traditional computer-assisted programs. (CC)

Suggests a few approaches that will enable a person with some programming experience to incorporate graphic teletype output into simulation programs of interest in chemical education. (Author/PR)
