The implementation of professional learning communities (PLCs) has led to systemwide reform within school districts and campuses regarding how campus leaders support the teachers' collaborative work and continued professional learning. Current research emphasizes the importance of campus administrators cultivating an environment where PLCs can flourish and ensuring that PLC teams have the resources to work effectively. However, campus administrators simply putting these supports in place does not make them effective. This study sought to explore campus leader and teacher perceptions of administrator actions that support PLCs for teachers in core-content subjects at two suburban north Texas high schools. An explanatory sequential mixed methods research design was utilized, and three data collections tools were used: an electronic survey, interviews with campus administrators and teachers, and the analysis of campus and PLC artifacts. Survey data indicated that participating teachers had an overall positive perception of the current campus practices which support PLC teams. Teacher interview data revealed that teachers preferred that campus administrators take a neutral role in PLC team meetings, that administrators ensure PLC teams are meeting the established campus PLC expectations, and that administrators observe the team, listen, and ask questions to help the team. Campus administrators viewed their actions within PLC teams to include listening and questioning, having difficult conversations, and helping teams brainstorm or offering ideas when needed. Teachers and administrators also identified supports for PLC teams they felt were missing. Recommended actions for campus administrators and recommendations for further research are also included.

Researchers have shown that effective use of student data by teachers can inform teaching practice, leading to improved outcomes on standardized tests. In order to improve declining test scores at the middle school under study, professional development on the use of data teams was implemented. However, a year after implementation, teachers were still not utilizing data within their professional learning communities (PLC) effectively or at all. This qualitative case study addressed the problem of the need for teachers to use data more effectively. The conceptual framework of the study was based on the models of PLCs by DuFour and of data teams by Love. The research questions addressed how teachers perceived and used data in their PLCs in order to improve instruction. Qualitative data were collected from individual interviews with 7 teachers, observations of 8 PLC meetings, and review of PLC documents. Triangulation and member checking were used to bolster trustworthiness of interpretations. The data analysis led to 4 common themes: teachers felt they were forced to use data, had excessive responsibilities within PLCs, were busy with other required tasks, and needed more training on data use. The findings led to the design of a 5-day professional development series on data teams to be implemented at the middle school. This study has the potential to increase teacher capacity in using student data to inform instruction and to improve student achievement at the local school and district levels.

Implementing the principles of a professional learning community (PLC) in public schools has become a popular strategy for meeting school quality and accountability expectations. Whether PLC implementation results in improved school ratings represents a gap in the literature. Three out of the 4 elementary schools in the participating school district experienced a significant drop in state ratings. The purpose of this quantitative study was to explore the relationship between the perceived depth of implementaiton of PLCs and a school's performance in terms of state ratingsGuided by the theory of the learning organization, this quantitative study was designed to identify the extent to which participants believed their schools operate as PLCs and to determine whether there is a significant difference in results between the participating schools. Participant perceptions of PLC implementation were measured through the Professional Learning Communities Assessment-Revised survey instrument. A total of 77 teachers across the 4 schools participated, and descriptive statistics were used to measure the level of PLC implementation. A one-way ANOVA was conducted to determine if there was significant differences in responses from the schools. The ANOVA revealed no significant differences in the responses between the school that did not experience a drop in ratings and the other schools. The results of this study could provide a framework to aid teachers and administrators to improve student learning by providing improved instruction. Quality instruction can lead to improved student learnings, and when student outcomes are improved, more students graduate and become productive members of their communities.

The purpose of this study was to examine the impact of a three-year Professional Learning Community (PLC) staff development initiative that took place in a suburban school district in Connecticut. An operational definition for PLCs was developed. This definition may prove beneficial for future research on PLCs. A comprehensive review of the current literature base was conducted, including the detailed examination of one earlier literature review (Vescio et al., 2008) and six empirical studies which examined the relationship between PLC-like initiatives and student performance. The present study builds upon the relevant literature base, specifically by attempting to determine the relationship between teacher collaboration and two dependent variables: changes in teachers’ instructional practice and student achievement outcomes. In addition, the study considered the relationship between the support provided by administrators to PLCs and student achievement outcomes. Achievement outcomes were measured by performance on Connecticut’s annual standardized assessments. Correlational and multiple regression analyses were conducted to examine the relationships between the variables. Survey data viii were drawn from a sample of 325 teachers, while student achievement data were drawn from a sample of approximately 2,270 students. A modest, statistically significant relationship was noted between administrative support for PLCs and student performance in both reading and writing. No statistically significant relationships were observed between collaboration and student achievement outcomes. A significant relationship was noted between collaboration and changes in instructional practice as measured by responses on the survey instrument. In addition, the interaction of teacher collaboration and administrative support served as a predictor for student performance in both reading and writing, suggesting that optimal learning occurs when teachers in PLCs collaborate at high levels while simultaneously receiving strong administrative support. The study concludes with a discussion of the implications of the findings for policy, professional practice, and future research on the topic of PLCs.

This study examined the relationships between leadership practices of principals and strength of schools as sustainable professional learning communities. Strength of schools as professional learning communities was measured using the Professional Learning Communities Assessment; leadership practices were measured using the Leadership Practices Inventory both Self and Observer protocols. Findings indicated that neither principal's self-perceptions of their leadership practices nor teachers' assessments of their principals' leadership practices were related to strength of schools as professional learning communities. Findings did indicate ten specific leadership behaviors of principals that appear to be more highly related to strength of schools as learning communities. Further analysis which focused on the two strongest learning community schools and the two weakest learning community schools indicated that three specific leadership behaviors within Kouzes and Posner's practices of modeling the way and enabling others to act appear to be the most strongly related to reculturing schools as sustainable professional learning communities. Principals who set a personal example of what they expect of others are most likely to lead schools that function as strong learning communities. Additionally, principals who build consensus around a common set of values are also most likely to lead strong learning communities. Finally, principals who develop cooperative relationship with co-workers are most likely to lead schools that function as strong learning communities.

The study was to determine the impact of a Professional Learning Community on student achievement as measured by the state's criterion referenced reading and mathematics achievement tests. Data for this study were extracted from the school district's student database. Two cohorts of 90 students each were randomly selected from a population of approximately 600 students in 3 schools that participated in a Professional Learning Community (treatment) and 3 schools that did not (control). Professional Learning Communities known as PLCs, can serve as a major theoretical framework to promote the improvement of classroom teachers' instructional practice, teacher effectiveness and student achievement. Reading and mathemtics mean scale scores were extracted at three time points (year 1, year 2, and year 3) across three grades (grade 3, grade 4 and grade 5). Test for equality of variance found that no statistically significant difference existed between the mean scale scores of the two cohorts at the beginning of the study. The findings revealed that both cohorts trend toward increased academic achievement from year to year individually; however, when compared to each other, no statistically significant difference existed. Further research is indicated to examine each PLC for implementation, support and leadership as they relate to the PLC and a focus on instruction and learning.

This qualitative case study examined the effect of PLCs on teacher self-efficacy, and whether the type of PLC structure on each campus affected efficacy. The overarching research question that guided the study was, to what extent does perceived teacher self-efficacy change as a result of the practice of PLCs? Participants were selected using purposive and convenience sampling. Ten teachers and two principals on two different campuses participated in teacher focus groups and one-on-one principal interviews, respectively. The available literature on the topics of professional development, professional learning, teacher collaboration, and teacher self-efficacy yielded the discovery that collaborative practices can be used to improve a school and/or district or used to enhance positive practices that already occur. This study adds to the body of research as it develops the area of teacher efficacy and influence of PLCs. Using the coding software, NVivo, focus group data were coded into themes and further comparisons were made with categories derived and saturated until conclusions were drawn. The data show teacher self-efficacy increases as a result of PLCs when teachers are able to experience positive feedback from teammates, shared leadership, trust and honesty, and a freedom to fail. For those teachers who are not on a campus where PLCs are present, the data suggest they created their own PLCs as the need arose. These teachers experienced all of the same benefits of those teachers on a campus where a formal PLC structure exited; however, their stress level was higher.

The purpose of this study was to examine the impact of the implementation of a structured professional learning community model referred to as Learning Team Meetings (LTMs) on teacher practice and student achievement from the perspective of teachers and instructional leaders at high-need schools. To accomplish this purpose, a multi-site case study was conducted at three school sites (an elementary, middle, and high school) all within the same region of one of the largest urban school districts in South Florida. Qualitative research methods, including one-on-one observations, interviews, focus groups, and review of documents were utilized to analyze, contrast, and compare perceptions,beliefs, and assumptions of the participants in the study. The participants included teachers, principals, assistant principals, instructional coaches, and Learning Team Facilitators (LTFs). A total of 20 participants were involved in the study. The conceptual framework for this study is rooted in the guiding principles of organizational learning and effective professional development practices. Professional Learning Communities (PLCs) offer formal structures to provide teachers with learning enriched, ongoing, job-embedded staff development (Hord & Sommers, 2008). This study focused on one trajectory or type of PLC, and sought to better understand the implementation of an organizational systemic knowledge transfer structure and the impact on teacher practice from the participants' perception. The research design profided thick, rich data, which offered in-depth understandings of the participants' perception, beliefs, and assumption about the LTMs' impact on teacher practice and student achievement. Through the research it was determined that participants among all three of the schools sites believed that LTMs were changing teacher practice. / Further, the participants at each of the school sites recognized the significance of the LTF and that he or she plays an essential role in the LTMs. The significance of the study,implications of these findings, and recommendations for further research are also presented. / by Ora Meles. / Thesis (Ph.D.)--Florida Atlantic University, 2011. / Includes bibliography. / Electronic reproduction.

This descriptive study investigated the development of the 5 dimensions of the professional learning community model in 5 economically disadvantaged and diverse Texas elementary schools, which demonstrated improvement in student achievement on the Texas Assessment of Knowledge and Skills (TAKS) over a 5-year period. Each of the schools were given the highest performance rating of Exemplary during the 2008 school year according to criteria developed by the Texas accountability system and had changed from an Acceptable rating in 2004. The purpose of this study was to determine the level of the development of the 5 dimensions of the professional learning community model in improving exemplary Texas elementary schools and to identify and compare the possible commonalities and differences existing between the schools on the 5 dimensions of professional learning communities. The 5 dimensions of the professional learning community model investigated in this study include: 1) shared and supportive leadership, 2) shared values and vision, 3) collective learning and the application of learning, 4) shared personal practice and 5) supportive conditions (collegial relationships and structures). The method used in this study was a mixed method approach that employed a questionnaire, individual principal and teacher interviews and school performance documents to collect data. The questionnaire data was analyzed through descriptive and analytical statistics while the interviews were investigated by identifying and documenting emergent patterns and themes. The findings from this study suggest that sustainable professional learning communities are evident in the high performing schools selected for this study. The study implies the culture of these schools is supported by relationships fostered by trust and mutual respect and their success is attributed to the collaborative, collegial and collective learning of the staff. Staff members from these schools are focused on student learning while campus leadership, grade level and vertical teams provide the structures for sharing leadership and collective learning. The principals in these schools engage in supportive behaviors that facilitate professional community while districts assist schools as professional learning communities in part through organized data and resource personnel.
