Ethnic minority students and low-income students are grossly underrepresented in
demonstrating interest and aspirations in science, evidence of science participation,
and subsequent capital. Members of these populations do not often embrace a STEM identity
or recognize that science, technology, engineering, and math are for them. While schools
struggle to innovate in terms of how best to engage and increase aspirations and opportunities
in STEM for these underrepresented populations, the family continues to be the most ignored
contributor to a student's STEM identity. Families play an important role in influencing their
students' attitudes, interests, aspirations, and achievements in STEM. While research exists
that points to a family's capital and dispositions towards science - known as habitus - to
influence their children's STEM identity, there is no research that examines deliberately-designed
STEM experiences for the family, as a direct intervention meant to enhance a students' science
identity. Given that identity development is a lengthy process, this study attended to the
hypothesized precursors: STEM capital and STEM family habitus. Specifically, this study sought
to answer in what ways designed STEM experiences were meaningful for families in the development
of STEM capital and the support of STEM habitus. Drawing on parent and student surveys after the
family STEM events, observations, and interviews, the findings demonstrate that the designed STEM
experiences were significant in building capital through meaningful conversations and connections.
The family's burgeoning STEM habitus was also made visible through developing interests, both by
parents and students. The designed STEM experiences were instrumental in connecting families to
STEM investigations, developing a community of learners, and providing access to STEM participation
they might not have had on their own. Implications of these findings for education stakeholders
include deliberate design methods to maximize family engagement and interest, as well as ways to
develop a STEM community of practice within underrepresented populations.
