In a "Scientist Spotlight" Intervention, Diverse Student Identities Matter.

We report on a brief, simple, online course intervention designed to reduce identity gaps and help students see their "possible selves" in working scientists. Students ( = 238) in a large-enrollment, introductory biology course for nonmajors were assigned nine podcasts, distributed throughout the semester. These podcasts each featured a scientist telling a "true, personal story about science," and we intentionally selected podcasts featuring scientists from diverse backgrounds.
