From Project to Publication
• This presentation describes how a critical incident study, by Phil Stokes, Ph.D. Candidate, went from NVivo project to publication.
• This study of knowledge in social science was used to understand the barriers that Hispanic/Latino students face in geoscience.
• Transcribed interviews were coded in NVivo using two multi-level node systems. Query results were exported for statistical analyses.
• Publication in GSA Today, the monthly peer-reviewed newsletter of the Geological Society of America
Why are there so few Hispanics in geoscience?

Aim of the study
• Geoscientists are in high demand both in the U.S. and around the world.
• In roughly 50 years, Hispanics/Latinos will be the majority in the U.S.
• Very few Hispanic/Latino students major in geoscience in the U.S.
• We explored the reported differences between Hispanic/Latino and white geoscience majors at a large university in the southwestern U.S.
Critical incident technique
• Developed during WWII to identify effective behaviors and predict likelihood of success for pilot trainees.
• A critical incident is self-reported experience which affects a person’s beliefs, values, or behaviors.
• Today, used in medical research and corporate hiring.
• For this research, a critical incident influences a student’s choice of major.
Collecting critical incidents
• We interviewed 29 current and former geoscience majors – 21 white – 8 Hispanic/Latino – 17 female, 12 male
• Interviews take ~45 minutes, follow approved human subjects protocols
• Identified a total of 881 incidents, or ~30/student
Research hypotheses
1. Hispanic/Latino students report more critical incidents relating to family and cultural issues than white students.
2. Hispanic/Latino students have a more negative undergrad experience overall as seen through critical incidents.
Classifying critical incidents
A co-worker asked what the student wanted to major in. The student replied, “I want to be a geoscientist; I want to do that.” The co-worker asked: “Why? You should become a nurse.” Later, the student told me, “It definitely grew my confidence.”
