Thesis advisor: Rebecca J. Lowenhaupt / Background: Examining the underlying social networks of a central office leadership team in a school district focused on accelerated improvement may provide insight into the organizational structures that support or constrain improvement efforts. These networks play a critical role in identifying strategies and practices that will enable district leaders to better support marginalized student populations and strive toward the goal of halving the achievement gap for all students. Purpose and Research Questions: The purpose of this individual research study is to carefully examine and analyze the structure of social relations in a school district under sanction, aiming to answer the following research question: How do social networks between and among district leaders relate to turnaround efforts designed to support marginalized populations? Methods: This study applies social network theory of central office leadership and relationships within a public school district aimed to accelerate improvement and support traditionally marginalized students. The network boundary is limited to central office administrators. In concert with the Dissertation in Practice (DIP), this individual study was designed to be emergent and flexible. Data sources include semi-structured interviews and document review. Findings: This study found that day-to-day, central office administrators in one turnaround district, rely heavily on a high number of external ties. The advice network is highly centralized around two key players which may constrain the exchange of advice or knowledge and ultimately slows or inhibits efforts designed to improve outcomes for marginalized student populations. High personnel turnover and lack of network stability are to be expected in a turnaround district, however, it has a ripple effect on the district’s ability to establish systems and structures that facilitate accelerated improvement for marginalized student populations. Significance. Organizational change is often socially constructed. Understanding which actors have positive influences and positive social relations will ensure that formal and informal network roles are identified and maximized to their full potential. Social network analysis has the potential to provide school districts information regarding the capacity of central office administrators to implement accelerated improvements. / Thesis (EdD) — Boston College, 2018. / Submitted to: Boston College.

This three-manuscript formatted dissertation interrogated the effectiveness of high-impact educational practices for marginalized students through the use of critical quantitative inquiry. The first empirical manuscript used data from the Wabash National Study of Liberal Arts education to explore the role of race and class on students’ engagement in and effects from high-impact practices. Findings from this manuscript suggest significant differences in academic motivation change over the first year of college when race and class were examined together, while no differences when just class was examined. The second empirical manuscript used data from the National Study of LGBTQ Student Success to examine the intersections of environment and participation in and effect from high-impact practices for lesbian, gay, bisexual, and queer (LGBQ+) students. Findings from this manuscript suggested that students’ perceptions of overall support and their relations with instructors mediated the influence that participation in high-impact practices had on students’ academic development. Finally, the third main manuscript considered the utility of critical quantitative inquiry and ways researchers can combine critical theory into quantitative research.

Thesis advisor: Lauri Johnson / This qualitative case study examined the perceptions of school and district leaders about fostering teacher leadership, specifically to support emergent bilingual and Latinx students in a public school district in the state of Massachusetts. The most recent model of transformational leadership developed from Leithwood’s research in schools (Leithwood & Jantzi, 2000) served as the conceptual framework. Data collection included 13 individual semi-structured interviews with district, building and teacher leaders as well as field notes and document reviews. Findings indicated that school and district leaders perceived they support formal and informal teacher leadership practices for emergent bilingual and Latinx students. Top-down approaches to collaboration and professional development impacted the development of teachers as leaders, creating barriers and challenges in each of three components of transformational leadership (setting direction, developing people, and redesigning the organization). Recommendations include establishing a collective vision for promoting and developing teacher leadership. Future research could be designed to better understand how teacher leadership is enacted to support issues around equity and social justice, and how we might encourage more teacher leadership among marginalized groups. / Thesis (EdD) — Boston College, 2020. / Submitted to: Boston College.
