Who chooses a pSTEM academic major? Using social psychology to predict selection and persistence over the freshman year

Abstract

AbstractMany social psychological variables, in addition to knowledge‐based factors such as academic preparedness, have been investigated individually as sources of the persistent gender gap in pSTEM (physical science, technology, engineering, and mathematics) fields. The present work tested all of these factors simultaneously and longitudinally, in a sample drawn from an incoming freshman class measured at three timepoints over the course of their first year. One thousand nine hundred and twenty‐nine students completed a survey with items assessing eleven social psychological constructs and were asked for permission to obtain institutional data regarding their academic preparedness and choice of academic major before matriculation, after the first semester, and at the end of freshman year. These social psychological and academic variables were used to predict pSTEM major status. Across multiple timepoints, and over and above academic preparedness, greater Math and Science Self‐Efficacy, rejection of the stereotype that scientist careers are unsociable in nature, having a pSTEM role model in high school, and lower endorsement of communal goals were consistently related to the selection of a pSTEM major. Students who endorsed entity theories of math and science abilities were also less likely to select a pSTEM over life and social sciences major. As a set, the factors accounted for roughly half of the gender difference in pSTEM major selection. Interventions aimed at reducing the gender gap in pSTEM major selection might do well to focus on these more psychological factors as well as academic ones.
