Gives driving directions for a circuitous route while asking the drivers to make observations, measurements, interpretations and to locate features. Includes an example for the LaSalle Quadrangle, Illinois, which takes about one hour to complete. (Author/MVL)

Describes the author's computer-based program for a subduction-zone-earthquake exercise. Instructions for conducting the activity and obtaining the program from the author are provided. Written in IBM QuickBasic. (PR)

Describes two basic types of software for beginning geology classes: general programs used to illustrate geologic phenomena (for example superposition) and programs written for specifically for geologic applications. (PR)

Described are the background, operation, and findings of the work of the deep sea drilling vessel Glomar Challenger, which has taken 8,638 core samples from 573 holes at 392 sites on the floor of the Earth's oceans. (SL)

Understanding the complex stratigraphic/structural relations produced during accretionary events is best achieved through "terrane analysis," wherein individual structural domains are discriminated and their geologic histories compared and analyzed for critical, paleogeographical significant information. Terrane analysis methodology,…

State geological surveys have a significant role in geologic education. They are the principal gatherers, evaluators, and distributors of geologic information within their states; and they are in daily contact with the public through state, government, industry, and educator contacts. Many surveys are attempting to disseminate information through…

Provides information about producing stereo slides and their use in the classroom. Describes an evaluation of the teaching effectiveness of stereo slides using two groups of 30 randomly selected students from introductory geomorphology. Results from a pretest/postttest measure show that stereo slides significantly improved understanding. (JM)

Changing ideas about the origin of the Silurian Clinton oolitic ironstones in eastern United States provide an instructive example of how interpretations develop as knowledge increases. (PR)

Spreadsheets are well suited to many geochemical calculations, especially those that are highly repetitive. Some of the kinds of problems that can be conveniently solved with spreadsheets include elemental abundance calculations, equilibrium abundances in nuclear decay chains, and isochron calculations. (Author/PR)

Sections in this article discuss (1) Science Literacy Needs; (2) Science Education Goals; (3) National Science Teachers Association; (4) Science, Sequence, and Coordination of Secondary School Science (SS&C); (5) Philosophy of SS&C; (6) Geosciences and SS&C; and (7) Geoscience Organization Contributions. (PR)

Describes activities to help students see discontinuities as faults. Students collect data, manipulate data, and use the data to formulate explanations. Schematic diagrams help students with the conceptual component of thinking. (PR)

Science exhibitions presented by college students at local elementary schools foster goodwill in the community; give college students an opportunity to share their science as role models; provide elementary school children with a positive, enjoyable approach to science; and can be organized rather easily following guidelines that outline…

A new classification of rocks that requires no tools other than a hand lens and that is both comprehensive and informative is described. Each of the three main rock groups is treated in two-dimensional, rectangular charts with additional appended boxes that provide optional mineralogical and textural terms that can be used in rock names. (PR)

Science teachers and teacher educators need to reexamine the geoscience content in their courses. Public ignorance about science, in general, and about key concepts of the geological sciences, in particular, inhibits effective action on problems relating to environmental change, land utilization, hazard mitigation, construction safety, cost…
