Preparing STEM majors for careers remains a significant challenge, and retention of undergraduate STEM majors has proven difficult at the University of Pittsburgh at Greensburg. The "Exploring STEM Identity through a Science Learning Interdisciplinary Community Expansion (SLICE)" project aims to enhance student skills and foster interdisciplinary connections through cohort experiences. The project focuses on how connections with peers and faculty impact STEM identity and how students develop expertise through career exploration. The SLICE program has implemented strategies to support scholars, including: 1) Cohorts, Summer Bridge, & Block Scheduling: These initiatives reduce barriers and foster authentic peer connections. 2) STEMinar: A first-year seminar that enhances time management, decision-making, and problem-solving while allowing scholars to explore their identities. 3) Short Courses & Mentoring: These tools help expand scholars' communication, technical skills, and self-efficacy. 4) Career Events, Research Projects, & Apprenticeships: Collectively, these methods aim to influence identity formation and retention by creating supportive, enriching environments while providing practical experience and exploring STEM fields. To evaluate the effectiveness of the program, qualitative (e.g., focus groups) and quantitative (e.g., academic performance, surveys) data have been collected for the scholars and a matched cohort. Preliminary results show that scholars have higher GPAs (3.69) than the control group (3.09). Scholars rated summer bridge activities highly, with strong engagement (4.70/5) and a high likelihood of recommendation (4.75/5). STEMinar feedback was positive, with students valuing the transition support, relationship building, and skill development. SLICE career events have been well-received; most students felt a strong connection with the professionals, saw career potential, and were inspired to pursue careers. Mentorships received positive feedback regarding faculty relationships, access, support, and advice. Scholars highlighted the importance of building connections through mentorship opportunities during focus groups. We hope continued participation in the program will increase retention and graduation rates and positive STEM identity formation.
