Although an awareness of the challenges facing rural schools is growing among education scholars, there remains a paucity of research on rural teachers and leaders. Furthermore, the vast majority of that research has been constrained to an extremely small number of rural-centric journals. Over one-half of all US school districts and one-sixth of all students are in rural contexts (Johnson et al., 2014), yet these constituents are often left behind or forgotten in debates on important educational issues, resulting in the continual undercutting of support for their teachers and educational investments. The authors of the collective of studies published in this special section of Educational Administration Quarterly (EAQ)-argue that specialized focus in a mainstream and non-rural specific academic journal will serve to validate and affirm the importance of research in this understudied area to a broader audience.

In this article, we draw on institutional theory and social network research to understand the factors enabling and constraining the cognitive repertoire principals draw on when solving problems. Methods: The data come from a field simulation of how 52 principals respond to and seek advice for two problem scenarios. Along with principals’ personal and school characteristics, we examine how the characteristics of principals’ professional networks are related to their problem-solving and reliance on institutional logics. Findings: Some imprecision in the model estimates notwithstanding, in this exploratory study intended to illuminate potential patterns for study in future research. We find evidence that principals draw on four institutional logics when solving problems: democratic and family logics, bureaucratic logics, professional logics, and market logics. Principals’ reliance on these institutional logics appears to be related to the closeness of the colleagues in their advice networks as well as the nature of the problem they are solving. Implications: One key contribution is to research is to reveal the subtlety of the social sensemaking involved in interpreting and taking action in institutional environments. The results also highlight which network characteristics might help principals respond more flexibly to new and complex problems in institutional contexts, such as racial equity.","PeriodicalId":48091,"journal":{"name":"Educational Administration Quarterly","volume":"59 1","pages":"306 - 338"},"PeriodicalIF":3.3,"publicationDate":"2023-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45828115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of our study was to conduct a comparative case study and explore how four district leaders promoted CRPs throughout each of their districts. Research Design: Situated in the Midwest, we used a comparative case study to explore the approaches of four Black women school district leaders. Data included a focus group interview with the leaders; four individual, follow-up interviews; and artifacts or documents provided by the leaders. The data collected was analyzed using the Culturally Responsive School Leadership analytical framework. Results and Discussion: Findings discuss school district leadership's responsibility to promote CRPs; district leaders’ ability to foster trusting relationships with educators; and district-wide efforts to engage in purposeful teacher retention practices.

This study utilizes an organizational theoretical perspective focusing on the role of school organization and leadership in the causes of, and solutions to, teacher shortages and staffing problems. Data/Methods: The study entailed secondary statistical analyses of the nationally representative Schools and Staffing Survey, its successor the National Teacher Principal Survey, and their supplement the Teacher Follow-Up Survey, conducted by the National Center for Education Statistics. Findings: The analyses document that, contrast to urban and suburban schools, the student population and teaching force in rural schools has dramatically shrunk in recent decades, that despite this decrease in students, and demand for teachers, rural schools have faced serious difficulties filling their teaching positions, and that these teacher staffing problems are driven by high levels of preretirement teacher turnover. Moreover, the data document that teacher turnover varies greatly between different kinds of schools, is especially high in high-poverty rural schools, and is closely tied to the organizational characteristics and working conditions of rural schools. Implications: Research and reform on teacher shortages and turnover have focused on urban environments because of an assumption that schools in those settings suffer from the most serious staffing problems. This study shows that teacher shortages and teacher turnover in rural schools, while relatively neglected, have been as significant a problem as in other schools.","PeriodicalId":48091,"journal":{"name":"Educational Administration Quarterly","volume":"59 1","pages":"396 - 431"},"PeriodicalIF":3.3,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46800213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Addressing these gaps in the literature, this study aims to identify teacher- and school-level latent profiles of teachers’ instructional practices and to investigate how distributed leadership predicts teachers’ membership in different instructional practice profiles, with the mediating role of teacher collaboration. Research Methods/Approach: The study employed a cross-sectional survey design using Türkiye's TALIS data for lower secondary education. Multilevel latent profile analysis with mediation modeling was conducted on data from 3,223 teachers in 192 schools. Findings: This analysis yielded four teacher profiles: laissez-faire, typical, controlling, and versatile; and two school profiles, high controlling and high laissez-faire. Findings indicate that distributed leadership promotes professional collaboration in lessons among teachers, which could, in turn, play a critical role in determining both individual teacher- and school-level profiles. Implications: This study provides practical contributions to understanding the nature of classroom teaching, suggesting that future studies should use instructional practice profiles instead of a single construct of teaching.","PeriodicalId":48091,"journal":{"name":"Educational Administration Quarterly","volume":"59 1","pages":"255 - 305"},"PeriodicalIF":3.3,"publicationDate":"2023-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41602762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The stability of educational districts depends on superintendents navigating relationships with their school boards, yet little research exists that addresses board–superintendent relationships in locally controlled districts. Using theories of local will and capacity, and community power relationships, I examine what factors shape the extent of local control enacted by school boards, and how these factors affect superintendent–school board relations. Research Methods: The qualitative case study design is bounded as one multi-district union superintendent and three rural school boards. Data collection included semistructured interviews, ethnographic observations, and document collection to understand the relational dynamics of local control. Data analysis included in vivo and a priori coding, and the development of analytic matrices. Findings: All boards demonstrated local will and some local capacity, which explained the dimensions of enactment of local control. Rural board capacity—tenure, expertise, and residency of board members—influenced the extent of local control. Cross-case analysis revealed a relationship between board capacity, community capacity, and board–superintendent relationships. These patterns are theorized as local control school board–superintendent relationships typology, based on board capacity and local community capacity. The relationships include role contestation, confusion, collaboration, and dependence. Implications for Research and Practice: The study expands the theory of local capacity to include community and board dimensions and describes the complexities of superintendent–board relationships. The study concludes with recommendations for practice, policy, and research on locally controlled school boards.","PeriodicalId":48091,"journal":{"name":"Educational Administration Quarterly","volume":"59 1","pages":"667 - 699"},"PeriodicalIF":3.3,"publicationDate":"2023-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48725764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the chief equity officer position is still in its early stages, we have an opportunity to examine insights from this work in the higher education context—both to support the adoption and implementation of the position, and the change work the chief equity officer will lead throughout the organization. The following conceptual question guides our analytical review: How can the role of chief equity officer be meaningfully and thoughtfully adapted for K-12 schools and districts in a critical anti-racist manner? Moverover, how might insights from higher education and scholarly knowledge on the nature of educational institutions, change within organizations, leadership practice, and learning inform the development of this role? Proposed Conceptual Argument: While the chief equity officer position was initially developed in response to historic and systemic inequities, over time, as this position becomes standardized through a process scholars call mimetic isomorphism, it runs the risk of becoming symbolic, only serving to signal an organization's commitment to equity-oriented work without meaningfully attending to its structures for learning, policies, or practices. Implications: Chief equity officers have a formal role within the district; however, their work requires an organizational commitment, from educators and educational leaders, for anti-racist systemic change. Structural, financial, and personnel-oriented supports are critical. Training programs for educators and leaders should thoughtfully prepare future chief equity officers, and continue to extend existing efforts to prepare anti-racist, equity-oriented principals, superintendents, teachers, and other educational leaders.","PeriodicalId":48091,"journal":{"name":"Educational Administration Quarterly","volume":"59 1","pages":"143 - 178"},"PeriodicalIF":3.3,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46941935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing theoretically upon brokering and social networks brokerage, analysis of transcripts used both deductive and inductive coding. Findings: We identified five key issues acted upon by leadership coaches, including: (a) relational issues between the aspirant and the mentor; (b) insufficient time between the aspirant and the mentor; (c) aspirant identification of and engagement with clinical work of developmental importance; (d) aspirant access to and/or authority for clinical work; and (e) the developmental supports provided to aspirants by mentors. Drawing upon theories of brokering, social networks brokerage, and third-party influence as we examined how coaches acted upon aspirant issues, we found that coaches regularly worked as brokers and third-party influencers in these pursuits. The structuring and design of coaching as well as coaching tools proved vital to this work.

Negative effects of shortages are linked to poor outcomes for students, teachers, and organizational climate and culture. However, less attention has been paid to the impact of shortages on principals’ leadership activities. Research Methods/Approach: This study uses qualitative data from 23 principals in four Oklahoma school districts to describe the impact of teacher shortages on principals’ leadership practice and the extent to which principals alter leadership behaviors in relation to shortages. Findings: Findings offer new evidence suggesting teacher supply, principal leadership, and organizational functioning are tightly coupled. Specifically, principals experienced competing managerial demands as they reported stronger impacts of shortages on tasks associated with organizational management, instructional management, and internal relations, while indirect or minor impacts were reported for administrative and external relations tasks.
