THE FOLLOWING IS THE FULL TEXT OF THIS DOCUMENT (Except for the Evaluation Summary Table): VERSION: 1.4E. PRODUCER: Earthware Computer Services, P.O. Box 30039, Eugene, OR 07403. EVALUATION COMPLETED: June 1982 by staff of NWREL and constituents of the Alaska Department of Education. COST: $49.50. ABILITY LEVEL: Secondary and College. SUBJECT:…

Reviews an educationally valuable and reasonably well-designed simulation of volcanic activity in an imaginary land. VOLCANOES creates an excellent context for learning information about volcanoes and for developing skills and practicing methods needed to study behavior of volcanoes. (Author/JN)

Suggests cooperative learning projects if only one microcomputer is available for a large class. An example of such a project using a program dealing with correlating sedimentary rock layers through cross-sectional analysis is described. Instructional strategies and academic objectives of the three-module program are included. (JN)

Presented is a description of a BASIC program to be used on an IBM microcomputer for calculating and plotting synthetic seismic-reflection traces for multilayered earth models. Discusses finding raypaths for given source-receiver offsets using the "shooting method" and calculating the corresponding travel times. (Author/CW)

Describes a computer program written in Microsoft BASIC for use on personal computers to calculate travel times of refracted waves in layered structures with arbitrary dipping interfaces. Exercises for student use are given to illustrate some of the basic properties of reversed refraction travel time graphs. (TW)

Describes how the graphics capabilities of the Apple Macintosh computer can be used in geological teaching by customizing fill patterns with lithologic symbols. Presents two methods for doing this: creating a dummy document, or by changing the pattern resource resident in the operating system. Special symbols can also replace fonts. (TW)

Describes how computer graphic methods can be used in teaching structural geology. Describes the design of a graphics workstation for the Apple microcomputer. Includes a listing of commands used with software to plot structures in a digitized form. Argues for the establishment of computer laboratories for structural geology classes. (TW)

Presents reviews by classroom teachers of software for teaching science. Includes material on the work of geologists, genetics, earth science, classification of living things, astronomy, endangered species, skeleton, drugs, and heartbeat. Provides information on availability and equipment needed. (RT)
