GEOLOGIC TECHNIQUES AND PROBLEM SOLVING: A COURSE FOR NEW MAJORS

Four years ago we introduced a new course into our curriculum for geology majors. Geologic Techniques and Problem Solving requires only one introductory geology course as a prerequisite and is designed to prepare students for their upper-division coursework. Whereas most lower-division courses focus on specific content, this course focuses on providing a framework for that content. Learning objectives are for students to be able to: (1) collect basic field data; (2) write a clear, accurate report describing their observations; (3) use topographic maps and aerial photographs; (4) locate and read geologic literature; (5) work with a group to investigate a problem and present results; (6) consider societal implications of the science. The overarching goal is to stimulate students to begin thinking and communicating as geologists, and to develop a context for the various sub-disciplines they will be studying.

We decided to make a weekend field activity the focus of the course, because most of our upper-division courses have a large field component and field skills continue to be required for geologists in nearly every employment sector. Prior to the field trip, students practice using Brunton compasses and topographic maps, and recording observations. During the trip, students collect basic petrologic, stratigraphic, and structural data. After the trip, students revisit the field site using aerial photographs and learn about the components of a geologic report. To develop their skills, students complete two drafts prior to final submittal; the first draft is reviewed by the instructor, and the second draft is reviewed by a fellow student.

For the last segment of the course, students are divided into groups and choose a specific topic to investigate further—for example, possible locations in the field area to drill water wells, or the tectonic setting of a time period when one of the formations was deposited. Students learn how to use online databases to find information about their topic, and they present their results to the class in a symposium modeled after professional conferences. Since we have implemented this course, students are better prepared to complete investigations and write reports in their upper-division classes, and they can more rapidly achieve an advanced skill level.
