Scientist Spotlights are homework assignments that highlight the personal and scientific stories of counterstereotypical scientists. Previous research has focused on whether these assignments promote possible selves in STEM (science, technology, engineering, mathematics). We sought to understand the value students themselves placed on the assignment using expectancy-value theory complemented by further analysis of the assignment's self-reported impacts on students. Therefore, at the end of an introductory biology course with several Scientist Spotlights, we asked students to reflect on how the course would influence them for years to come. We found that although the assignments had low instrumental value, 49% of students mentioned Scientist Spotlights or a highlighted scientist. Thematic analysis on the Scientist Spotlight--related parts of the reflections found novel emergent themes including "diversity in science," "humanizing scientists," and "self-efficacy." Most students mentioned multiple themes, with few differences between students from minoritized and nonminoritized groups. We interpreted our results through the lens of the "mirrors, windows, and sliding glass doors" framework, as Scientist Spotlights appeared to function as "windows" into the diverse scientific world, "mirrors" for seeing human traits in scientists, and "sliding glass doors" inviting students further into science. Our study expands our understanding of the broad, multiple, and intersecting impacts of Scientist Spotlights.
