Described is the use of a microcomputer and computer software to simulate the use of geological equipment. The technique uses pictures of the control panel (with switches and dials that can be activated) and a story board that can provide the simulation. A simple seismograph is used as an example of possible simulations. (RH)

Describes a learning activity when students construct a model of a buried valley by using computer assistance. Explanation of the problem includes mathematical models and illustrations. (MA)

Described is a set of FORTRAN programs, suitable for teaching and research purposes, that simulate contact and regional metamorphism. Equations, examples, program uses, and availability are discussed. (CW)
