The role of the principal has become increasingly complex and challenging. Recent emphasis has been placed on the role of principals as leaders who can build a culture of learning in schools to close the student achievement gap. Outside factors such as fast-growth in Texas have caused schools to change and grow quickly, which increases the learning demands placed on principals as they seek to develop the knowledge and skills needed for effective leadership. Developing and sustaining a professional learning community is a powerful strategy that has been found to improve teaching and learning, however developing professional learning communities requires skilled leadership. Limited research exists regarding how principals learn to implement and sustain professional learning communities within fast-growth districts, therefore, with this phenomenological qualitative research, I explored the lived experiences of seven principals within one fast-growth district in Texas to explore how they learned to develop and sustain a professional learning community.

The purpose of this mixed methods study was to determine which dimensions, as represented by the Professional Learning Community Assessment – Revised dimensions, are present in the environment of North Texas elementary schools and their impact on student growth. A survey design was utilized in which elementary principals and teachers in a selected school district completed the Professional Learning Community – Revised survey developed by Hipp and Huffman (2009), to gather perceptions of PLC implementation within their school environments as well as reflect strengths and needs regarding each dimension. The results of the survey were analyzed and one-to-one interviews were completed to clarify and support survey results. Bivariate and multiple regression analysis were used to determine correlations between dimensions present in a school’s environment and their impact on student growth. The study found a statistically significant relationship between the dimensions of shared values and vision and shared personal practice and math growth. Although PLCA-R dimensions were not found to be statistically significant in predicting reading and math growth, the effect sizes were notable at 22.4% for reading growth and 15.8% for math growth. This study’s findings provide important information which educators can use to implement practical application of Professional Learning Communities within their schools and districts. By understanding which dimensions are present within a school’s environment as well as their impact on student growth, educators can continue to increase knowledge and develop a focused plan for implementing strategies which are effective in strengthening teaching and learning in order to increase student achievement.

The present study used Nardi and O’Day’s (1999) information ecology theory, along with activity theory (Wertsch, 1998), social learning theory (Wenger, 1998), and situated learning theory (Lave, 2009; Lave & Wenger, 1991) to examine the informal professional learning of a high school social studies department. Existing literature is just beginning to attend to the potential of informal professional learning, so this exploratory study used a single-case study of a high school social studies department made up of 12 teachers. Data included observations of scheduled and spontaneous collaborative learning activities, department meetings, and in-service meetings; semi-structured interviews; and relevant documents to consider how high school social studies teacher participants navigate their own informal professional learning. Supporting research questions included: (1) How do high school social studies teacher participants choose what to do to individually and collectively meet their professional learning needs? (2) What actions do participants take to meet their professional learning needs individually and collectively? (3) How do participants evaluate their professional learning growth individually and collectively? (4) How do participants interact with one another and with the environment as they navigate their own professional learning? Results indicated that participants valued their informal professional learning experiences, engaged in reflection throughout their informal professional learning, were influenced by departmental leadership, and experienced successes and failures in their informal professional learning goals. The department’s informal professional learning was important but also imperfect. Further consideration of teachers’ informal professional learning may offer new ways to support teacher growth.

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.

The purpose of this qualitative study was to explore the leadership practices of principals who sustain professional learning communities. The study was conducted using semistructured interviews with 2 elementary school principals from a noted professional learning community district in Henderson, Kentucky. A Professional Learning Community Assessment Survey was completed by the teachers in both elementary schools. Photographs of each school and a review of school documents triangulated the research of these 2 professional learning communities. In interviews the principals described their roles in: (1) defining a professional learning community or PLC, (2) supporting and sustaining a PLC, (3) supporting professional dialogue opportunities in a PLC, and (4) identifying shareholders as an essential element in successful professional learning communities. The teacher surveys helped to confirm the principals' perceptions and the roles of the principals in supporting and sustaining a professional learning community. The teachers defined the principal's role in supporting and sustaining a professional learning community as (1) involving staff in decisions, (2) incorporating teachers' advice to make decisions, (3) providing staff members access to key information, (4) the principal being proactive, (5) enabling staff members to initiate change, (6) sharing responsibility and rewards, (7) sharing power and authority, and (8) promoting and nurturing leadership. The effective leadership practices of both principals support successful and sustainable professional learning communities. The triangulation of data reinforced these conclusions: (1) both principals have effective leadership practices that support and sustain a PLC, (2) the majority of teachers from both schools who participated in the survey overwhelmingly approve of the leadership practices of their principals, (3) continued improvement in student assessment results over a period of years support the practices of the principals, and (4) effective leadership practices strengthen the professional learning concept of supporting and encouraging continued student and teacher progress. The results from this study were intended as a reference for principals and school districts concerning the effective practices of principals to support and sustain professional learning communities.

The purpose of this research was to understand the role of district leadership better in the implementation and development of professional learning communities. This investigation was a mixed-methods analysis of the perceptions of a school district's support in the implementation of professional learning communities (PLCs) at the school level. Additionally, in this study, I examined how the PLC framework supports systemic school improvement, using Hord's definition of the five dimensions of a professional learning community. A PLC literature review informed the study. A school district of approximately 14,000 students, and a high school of 2,219 students was selected as the population sample. One hundred high school staff members and 20 central office administrators completed the PLCA-DS of Professional Learning Community Assessment-District Support, developed by Olivier, Huffman and Cowan, to measure both school and district level personnel's perspectives regarding the district's role in the implementation of PLCs at the school level. Semi-structured interviews were conducted with district personnel as well as school leadership and professional campus based staff, which played integral roles in the development of professional learning communities. These roles include the school principal, assistant principal, liaison and other staff who are working collaboratively at the school and district levels to support PLC implementation. The investigation results indicated the importance of leadership and culture throughout this change process and critical to school improvement as evidenced by the study of District A and High School A1.

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.

According to recent research, approximately 40-50% of teachers leave the profession within the first 5 years, creating a constant need for teachers. There is evidence that creating a supportive working environment through effective professional learning, drawing on adult learning theory, may reduce teacher turnover and increase student performance. This study explored teachers' perceptions about the professional development offerings available to them, how these perceptions influence their decisions to remain at the school, and what types of professional learning experiences teachers want to experience. Fourteen high school teachers participated in individual interviews and 2 focus groups, which were analyzed inductively for themes. Participants revealed that voice, choice, effective professional development, time, collaboration, school climate, and the district's professional development program were instrumental in creating a supportive environment. These results suggest that creating professional learning programs that incorporate the attributes of effective professional learning and encourage teacher participation are important at all points of the process. A professional learning plan project was designed in response to the study findings and recommendations. This study may lead to social change by providing the target school district and its building level administrators with a plan for professional learning based on teacher input, effective practices, and adult learning theory to use as a viable method to retain effective educators that, in turn, may result in improved student performance.

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.
