Holistic mentoring ecosystems are a comprehensive approach to addressing the diverse needs of students through interconnected support networks. While mentoring has been well-documented in existing literature, more research is needed to determine the effectiveness of mentoring ecosystems in mitigating the impact of critical junctures for vulnerable, high-attrition student populations. Guided by Tinto’s model of retention, this qualitative case study investigated the role of holistic mentoring ecosystems in mitigating the impacts of the two combined critical junctures—the COVID-19 pandemic and the first year of college—on low-income STEM undergraduates. Our findings suggest that holistic mentoring ecosystems were essential in helping students adjust to the academic environment and fostering a sense of belonging in the STEM community amid the severe limitations imposed by the pandemic. This study adds to the growing body of literature investigating the approaches and strategies effective in supporting vulnerable student populations through critical junctures in their educational journey. 

Grounded in a conceptual framework incorporating intersectionality, motivation, self-determination, and self-efficacy, this empirical study investigated how individuals’ identities, mindsets, and resources in educational environments intentionally cultivated to support their decision-making, development, and connections in the science community, can significantly increase the recruitment, persistence, and success of low-income, academically talented science students from diverse backgrounds. Several factors—academic performance in coursework, self-image, self-agency, financial support, and social integration in the science culture—continue to significantly impact student retention and persistence in STEM disciplines. Many of these factors are negatively affected based on a students’ intersecting identities, which can be detrimental to their academic success if not addressed. We found that additional considerations to factor in concerning low-income students from diverse backgrounds that is pertinent to supporting their persistence and success in the postsecondary STEM educational context. 

Undergraduate research and international experiences are often described as high-impact educational practices beneficial for undergraduate student success and for supporting the development of science identity and intercultural competencies. While several studies have investigated the impact of undergraduate research on students from minoritized groups, fewer studies have focused on their engagement in global experiences, and fewer still have explored their engagement in international research experiences. Drawing on the theoretical frameworks of Science Identity, Social Cognitive Career Theory, and the Intercultural Competence Model, this present study explores the benefits of participating in an international research experience for minority undergraduate scientists. Using a qualitative case study methodology, we examined the evolution of students’ science identity, research competencies, and intercultural competence after engaging in a three-month international research opportunity in France and Belgium. We found that after participating in international research, minority undergraduate scientists had: 1) Increased confidence in their science identity and abilities; 2) Gained and strengthened skills necessary to be a successful researcher, 3) Recognized the influence of international exposure on their growth personally and professionally, 4) Expressed how monumental this research opportunity is for all minority students to experience. Our findings suggest substantial benefits from an international research experience on the development of minority undergraduate scientists.
