TEACHING QUANTITATIVE SKILLS IN THE GEOSCIENCES

The ability to effectively use quantitative reasoning and skills is increasingly important for modern geoscientists. For example, Sophisticated applications of calculus and inversion theory underpin our understanding of the structure and deformation of the solid Earth; multivariate statistical analysis enables our interpretation of the Earth's chemical evolution; and complex computer models help us investigate the impact of changes in ocean dynamics on the climate system. Because they underpin so much of geoscience, quantitative skills are an essential part of the geoscience major. Introductory geoscience courses play an especially significant role in students' understanding of the use of quantitative arguments and problem solving. Upper level division courses continue the development of the quantitative base required for further work in the profession. Increased emphasis on these skills can present geoscience faculty with new challenges for effectively conveying the importance of quantitative skills to the students.

To assist faculty in meeting these challenges, the Science Education Resource Center and its partners are developing the Teaching Quantitative Skills in the Geosciences website . This site brings resources from mathematics education together with examples for teaching quantitative skills in the geosciences and includes discussions of methods, teaching activities, and a special section of resources for students. Current work is focused on creating cross-referenced pages addressing mathematical concepts important in entry-level courses and the geoscience context(s) in which they are taught,. A pair of workshops in June 05 will bring together faculty who teach upper division climate change and Earth surface processes to develop new examples (and supporting materials) of ways to teach these subjects quantitatively. Faculty are are invited to contribute to the example collection, apply for this year's workshops, or review the site content. This site is part of the Digital Library for Earth System Education.
