More diverse representation in undergraduate classrooms may be an important step towards turning science, technology, engineering, and mathematics (STEM) disciplines into more inclusive communities. In the United States of America, the individuals whose work is discussed in typical introductory science courses collectively do not represent the diversity of students’ identities in the classroom and further reinforce existing stereotypes of scientists as male, white, and aged. Here we report on the implementation of a semester-long intervention in an introductory-level geoscience course at the University of South Florida, USA. We introduced students to individuals with marginalized identities who are either scientists or have had a major influence on science and conducted semi-structured interviews with students from the course’s previous semesters. Analyses of these interviews indicate that participants with marginalized and non-marginalized identities broadened their preconceptions of who belongs in science and the range of identities among scientists. We suggest that interventions like these could foster feelings of belonging in the STEM community and, with repeated efforts, reduce harmful stereotyping and microaggressions against underrepresented scientists.

Building on suggestions from alumni from a recent interview project, students in Computational Geology at the University of South Florida were tasked with reading a popular non-fiction book on mathematics and writing about the book and their feelings about math. The book, The Math Instinct by Keith Devlin, was chosen because we believed it would give the students something interesting to write about and not because we had any expectations in particular about what it might reveal about or do for their math anxiety. The nature of the responses received from the students led to the performance of a post-hoc study on the emotional affect of math in the students' lives and how it changed as they proceeded through the book and reflected back on it at the end. Of the 28 students in the fall 2016 section of the course, 25 had an improved or slightly improved attitude toward math by the end of the semester. The assignment was more successful than we could anticipate at generating thought and getting students to communicate about math -an integral component of quantitative literacy. Although the limited size and post hoc nature of the study make it difficult to generalize, the results are promising and invite further use of the assignment in the course.
