Although an increase in their participation could reduce workforce shortages and diversify innovations in the architecture, engineering, and construction (AEC) industry, African American women remain significantly underrepresented in male-dominated AEC careers. Furthermore, partly due to the lack of early and meaningful AEC exposure, African American girls tend to have low interests in AEC careers. AEC infused out-of-school time (OST) programs have been successful in increasing middle-school girls' AEC career self-efficacy and interests. However, there is limited understanding on how salient identities interact with learning experiences in AEC-infused OST learning environments to impact AEC career interests. The purpose of this research is to investigate how the salient identities of African American middle-school girls interact with learning experiences within a developed femalized AEC Kinesthetic Learning Model (fAEC-KLM) to impact AEC career interests. Adopting Lent's social cognitive career theory, the gender and culturally responsive fAEC-KLM is a five-day AEC-infused OST program that engaged 14 African American middle-school girls in bridge-building projects, a panel session with female and African American AEC undergraduates, interactions with female and African American AEC professionals, and success stories featuring female and African American AEC professionals. Using a mixed method approach, data from interviews, surveys, tests, and observations are analyzed to assess changes in AEC career knowledge, self-efficacy, outcome expectations, and interests. Results show that the most effective fAEC-KLM components were lectures, bridge construction project, and peer interactions which improved AEC career knowledge, self-efficacy, and sense of belonging respectively. These in turn increased AEC career interests and three interest categories (active, passive, and null) are utilized to explain how varying fAEC-KLM interactions contributed to three different levels of AEC career interests. The findings align with prior career development and intersectionality frameworks. Findings also fill a critical gap in career development literature by providing insights into AEC career interest development processes in African American middle school girls through OST programs while highlighting how gender and culturally responsive approaches foster interests. Insights and recommendations contribute to ongoing literature to support interventions and policies that foster more equitable representation in AEC careers, increase diversity in AEC innovations, and reduce workforce shortages.
