Undergraduate Research Experiences as Preparation for Graduate Study in Geology
David William Mogk, Montana State University
Preparation of geology students for graduate school must go beyond mastery of information presented in coursework. Participation in directed research projects, such as a senior thesis, affords the opportunity for students to develop research questions, conduct literature searches, test hypotheses, design sample collection and preparation programs, collect data and analyze the results, and present a final product in oral and/or written formats. The practical aspects of working within a budget and meeting deadlines are added benefits. Development of these transferable skills prior to admission to graduate school benefits students, institutions, and the community-at-large.

Description, Analysis, and Critique of the Method of Multiple Working Hypotheses
William L. Blewett, Shippensburg University of Pennsylvania
The concept of Multiple Working Hypotheses, first described formally for geologists by T.C. Chamberlin (1890), involves the consideration and evaluation of two or more provisional hypotheses during an investigation. Analysis of the method indicates that it suffers from serious limitations, including: (1) questions regarding the assumptions underlying the hypothetico-deductive model of scientific confirmation, (2) problems inherent in the falsification of hypotheses, (3) questions regarding the method's applicability to natural phenomena with complex causes, (4) difficulties in reducing the initial class of hypotheses, and (5) lack of a logical bases for generating implications from hypotheses. Despite these drawbacks, the method has been applied successfully in scientific research and continues to serve as a valuable investigative approach in modern field studies.

Field-Trip Crises Large and Small
Robert M. Norris, University of California - Santa Barbara
Although field trips are an essential component of any well rounded course of instruction in geology, they can be sources of considerable difficulty for the field-trip leaders and for timid university administrators who fear the legal consequences of accidents. Many sorts of problems do, in fact, occur on field trips. Some are due to student or faculty error, others to mechanical problems with vehicles or equipment, and yet others to unexpected events or weather. Despite these problems and risks, the irreplaceable instructional value, the personal camaraderie, and the enjoyment shared by participants fully justifies taking the trips.
