Demonstrating petroleum engineering concepts in undergraduate laboratories often requires expensive and time-consuming experiments. To eliminate these problems, a graphical simulation technique was developed for junior-level laboratories which illustrate vapor-liquid equilibrium and the use of mathematical modeling. A description of this…

Discussed is the treatment of the concept of atomic orbitals in college chemistry textbooks; specifically the nodal surfaces of hybrid orbitals. Presented is a method of illustrating and introducing hydrogen-like atomic orbitals using computer graphics. (CW)

Describes an accurate system for measuring speeds and frequencies with a microcomputer. Explains how the system can give a reasonable graphical representation of velocity and acceleration against time. Gives examples of graphs produced by the program and provides an address to obtain the software for their application. (CW)

Describes the use of computer spreadsheet programs in physical chemistry classrooms. Stresses the application of bar graphs to fundamental quantum and statistical mechanics. Lists the advantages of the use of spreadsheets and gives examples of possible uses. (ML)

Describes a college level course in which computer mapping is incorporated into the geography curriculum. Discusses problems associated with using commercial mapping software in the general geography classroom. Concludes that students have reduced computer anxiety and a better understanding of geographic concepts as a result of the computer…
