Science Identity in Undergraduates: A Comparison of First-Year Biology Majors, Senior Biology Majors, and Non-STEM Majors

We argue it is important for everyone to possess basic scientific literacy for multiple reasons. Viewing oneself as a science person or not can impact one's confidence and willingness to engage with science content thereby improving science literacy. Identifying as a science person may develop early but is not fixed and may shift through science identity work. We investigated science identity views between STEM (science, technology, engineering, and mathematics) and non-STEM majors and assessed whether these views may be influenced by science identity work. Our questions were as follows: (1) How does science identity perception differ between non-STEM and STEM majors? (2) How do non-STEM and STEM students' perceptions of their science identity change over time? (3) How do non-STEM majors describe a science person compared to STEM majors? We surveyed first-year biology majors, senior biology majors, and non-STEM majors to address our research questions. We found significant shifts in science identity in non-STEM majors taking a general education lab science class pre-course and post-course, differences in agreement regarding science identity between groups, and differences in how a science person is defined among the groups. Our data suggest that instructors can scaffold and support students' science identity work to increase confidence, STEM retention, and ultimately can improve overall scientific literacy.
