摘要

Background

STEM participation is at record highs, yet scientific knowledge often fails to translate into effective responses to urgent social and environmental challenges, resulting in a growing knowledge–action gap. This study examines how early college students’ STEM career motivations are likely to either reinforce or disrupt this gap, focusing on the role that prior STEM experiences play in how they intend to “do” STEM. Drawing on rich survey data about students’ PK–12 exposure to STEM, we ask what kinds of STEM futures become more likely under different constellations of pre-college experiences.

Results

We analyzed survey data from 15,725 first-year students at 119 U.S. institutions, modeling STEM enjoyment and four career motivations (helping others, making money, job security, abundant opportunities) as predictors of STEM career intentions. STEM enjoyment was a strong positive predictor, while a desire to help others was associated with lower likelihood of intending a STEM career. Among the 3729 students who did intend STEM careers, cluster analysis identified three profiles: students who both enjoy STEM and strongly value helping others, students who pursue STEM to help others despite low STEM enjoyment, and students who enjoy STEM but place little emphasis on helping others. Despite the overall negative association, roughly two-thirds of STEM-intending students fell into profiles where helping others was central. We trained a machine learning model to use 389 variables on prior STEM experiences to predict their motivational profile. Relational STEM engagement—talking and participating in STEM with friends and family—emerged as the strongest differentiator: students who both enjoyed STEM and wanted to help others reported highest relational engagement and encouragement, whereas communally motivated students with low STEM enjoyment reported consistently lower support.

Conclusions

The findings suggest that many STEM-aspiring students already imagine their futures in ways that center helping others, but that the relational conditions that support these communal orientations are unevenly distributed. Patterns in pre-college experiences point to shared STEM talk and activity with friends, family members, and other adults as promising sites where educators and institutions can act to sustain and amplify communal motivations within STEM pathways.
