Undergraduates Discovering Folds in “Flat” Strata: An Unusual Undergraduate Geology Field Methods Course

Abstract

ABSTRACTUndergraduates learned to measure, map, and interpret bedding plane attitudes during a semesterlong geology field methods course in a field area where strata dip less than 9°. Despite the low dip of the strata, 2011 field course students discovered a half-kilometer-wide structural basin by using digital levels and Brunton pocket transits to measure bedding plane attitudes at numerous outcrops along a riparian greenway. Students reproduced faculty dip directions in all five structural domains and mean bedding plane attitudes in four of five structural domains (p < 0.05). Of 21 students who completed a field map, only 6 had trouble either measuring and plotting attitudes or drawing and labeling geologic contacts. The mean student evaluation score was 4.1 on a 5-point scale, and all seven evaluation category means were well within one standard deviation of departmental means. However, the course evaluated poorly relative to the other five junior- and senior-level geology courses taught during fall 2011 because mean evaluation scores for those courses ranged from 4.2 to 4.9. Results show that students can learn to measure, map, and interpret bedding plane attitudes in a field area where strata dip less than 10°.
