Science, technology, engineering, and mathematics (STEM) education has become an emphasized component of PreK-12 education in the United States. The US is struggling to produce enough science, mathematics, and technology experts to meet its national and global needs, and the mean scores of science and mathematics students are not meeting the expected levels desired by our leaders (Hossain & Robinson, 2011). In an effort to improve achievement scores in mathematics and science, school districts must consider many components that can contribute to the development of a classroom where students are engaged and growing academically. Computer technology (CT) for student use is a popular avenue for school districts to pursue in their goal to attain higher achievement. The purpose of this study is to examine the use of iPads in a one-to-one setting, where every student has his own device 24/7, to determine the effects, if any, on academic achievement in the areas of mathematics and science. This comparison study used hierarchical linear modeling (HLM) to examine three middle schools in a private school district. Two of the schools have implemented a one-to-one iPad program with their sixth through eighth grades and the third school uses computers on limited occasions in the classroom and in a computer lab setting. The questions addressed were what effect, if any, do the implementation of a one-to-one iPad program and a teacher’s perception of his use of constructivist teaching strategies have on student academic achievement in the mathematics and science middle school classrooms. The research showed that although the program helped promote the use of constructivist activities through the use of technology, the one-to-one iPad initiative had no effect on academic achievement in the middle school mathematics and science classrooms.

This dissertation employed a mixed-methods approach to examine the relationship between spatial reasoning ability and understanding of chemistry content for both middle school students and their science teachers. Spatial reasoning has been linked to success in learning STEM subjects (Wai, Lubinski, & Benbow, 2009). Previous studies have shown a correlation between understanding of chemistry content and spatial reasoning ability (e.g., Pribyl & Bodner, 1987; Wu & Shah, 2003: Stieff, 2013), raising the importance of developing the spatial reasoning ability of both teachers and students. Few studies examine middle school students’ or in-service middle school teachers’ understanding of chemistry concepts or its relation to spatial reasoning ability. The first paper in this dissertation addresses the quantitative relationship between mental rotation, a type of spatial reasoning ability, and understanding a fundamental concept in chemistry, the particulate nature of matter. The data showed a significant, positive correlation between scores on the Purdue Spatial Visualization Test of Rotations (PSVT; Bodner & Guay, 1997) and the Particulate Nature of Matter Assessment (ParNoMA; Yezierski, 2003) for middle school students prior to and after chemistry instruction. A significant difference in spatial ability among students choosing different answer choices on ParNoMA questions was also found. The second paper examined the ways in which students of different spatial abilities talked about matter and chemicals differently. Students with higher spatial ability tended to provide more of an explanation, though not necessarily in an articulate matter. In contrast, lower spatial ability students tended to use any keywords that seemed relevant, but provided little or no explanation. The third paper examined the relationship between mental reasoning and understanding chemistry for middle school science teachers. Similar to their students, a significant, positive correlation between scores on the PSVT and the ParNoMA was observed. Teachers who used consistent reasoning in providing definitions and examples for matter and chemistry tended to have higher spatial abilities than those teachers who used inconsistent reasoning on the same questions. This is the first study to explore the relationship between spatial reasoning and understanding of chemistry concepts at the middle school level. Though we are unable to infer cause and effect relationship from correlational data, these results illustrate a need to further investigate this relationship as well as identify the relationship between different spatial abilities (not just mental rotation) and other chemistry concepts.

The purpose of the study was to examine the role of leadership and school culture on the integration of technology to support instruction for students with emotional and behavioral disorders (EBD). A multiple embedded case study design was used to describe how a school leadership team supports a school culture for technology integration within classrooms where special education teachers integrate technology to engage students with EBD. The primary case of school culture includes a comprehensive description of how the school leadership team supports a culture for technology integration within classrooms. Embedded cases within the primary case describe how special education teachers integrate technology to engage students with EBD in classroom instruction. Technological Pedagogical Content Knowledge (TPACK) (Koehler & Mishra, 2005) is part of the conceptual framework to theoretically undergird the study. The findings of this study describe a school that serves students with EBD where there is a strong school culture and leaders support teachers who integrate technology to engage students. Patterns from the analysis indicate school leaders plan for staff development, participate in staff development sessions with teachers, observe teachers, provide feedback about teacher performance, and praise and encourage teachers to integrate technology. Teachers and leaders engage in formal and informal staff development opportunities to learn how to integrate technology into classroom lessons. As a result of these trainings and school leader support, teachers provide clear expectations for students while integrating technology to engage students, provide direct instruction, choices, and visual representation of content.

The purpose of this narrative inquiry study was to investigate the influence of curricular mandates on the teaching practices of high school mathematics teachers. Narrative inquiry, philosophically based on John Dewey’s theory of experience (Dewey, 1938), provides the intimate study of an individual's experience over time and in context(s) (Clandinin & Connelly, 2000). This study focused on the experiences of three high school mathematics teachers’ stories of educational change with data collected through interviews and personal documents. Socio-cultural narrative analysis was used to interpret the participants’ stories of adaptation. The data, presented as an ethnodrama, is composed of scenes taken from the interviews and interweaves the participants’ stories of evolution as they tackled the struggles of change on multiple levels: curriculum, student assessment, and teacher evaluation. Results indicated teachers adopt both traditional and reform strategies when deciding on appropriate teaching practices. Collaboration and professional development were two important aspects used by the participants to enlarge their toolbox of teaching practices when forced to challenge their existing beliefs. This study contributes to the scarce research on the impact of curricular mandates on teaching practices. It also highlights the experiences of high school mathematics teachers as they embrace the paradigm shift associated with the mandates and implement changes to their practices to promote a more student-centered, collaborative environment.

Traditionally, models of instructional leadership espouse data-informed decision making in response to student assessment outcomes as one of the core school leader behaviors. In recent years, rising expectations from accountability policies and related assessment practices have myriad implications for school districts, specifically in the areas of standards-driven reform, student assessment systems, and professional development models. As a result, demands on schools to collect and use student assessment data to inform curricular and instructional decisions has expanded. While principals are typically held responsible for school improvement efforts, more contemporary models of instructional leadership incorporate teachers as classroom-based leaders of assessment practices in forums such as professional learning communities. School and classroom assessment leaders engage in behaviors such as (a) identifying an assessment vision, (b) fostering group goals, (c) providing a model of data- informed decision making, (d) promoting teacher job-embedded professional learning experiences, (e) evaluating instructional practices with specific feedback, and (f) strategically aligning resources to school improvement goals. Unfortunately, school districts face many challenges with assessment leadership due to barriers in beliefs about assessments, time with and access to tools and training, and knowledge and skills about how to operationalize effective assessment practices that yield positive student outcomes. The purpose of this study was to explore assessment leadership as a construct among P-12 school and classroom leaders in one large district in Florida. Data were collected using an Internet-based survey constructed from existing qualitative and quantitative measures of key components of assessment leadership established in the literature. A series of descriptive and inferential analyses were conducted to (a) explore the factor structure of the instrument and (b) evaluate the influence of assessment learning experiences, beliefs, and knowledge on assessment practices. Relationships among variables were examined when considering moderating variables for school role (i.e., school-level administrator or classroom teacher as professional learning communities facilitator) and school type (elementary or secondary). Limitations were discussed to inform future research in this critical area of school improvement.

Instructional coaching has been a professional learning opportunity that many school districts have employed to support teacher practice. Pairing instructional coaching with on-going workshops is a relatively new approach to professional development. Participants for this study include fourteen middle school teachers that teach either mathematics or collaborate with special needs students. This study examines the effect that pairing instructional coaching with on-going workshops (with a primary focus on proportional reasoning) has on participants’ content knowledge and their perceptions of coaching. Drawing on Wenger’s community of practice theory and post-modern theory of power, this study employs mixed-methods design. Pre- and post-tests for proportional reasoning were administered to analyze the extent to which content knowledge changed over the course of the study. Pre- and post-interviews were conducted with each participant to determine any misconceptions each had on proportional reasoning and their perceptions of coaching (before and after the study’s instructional coaching). Grounded theory and thematic analysis was employed on the pre-and post-interviews to examine the role that power played in the participants’ perceptions of effective coaching attributes. Results suggest that (a) instructional coaching coupled with on-going professional workshops can change content knowledge in participants; (b) perceptions of coaching can change as the result of experiencing a coaching relationship and (c) power dynamics in the coaching experience determine the extent to which participants see the effectiveness of coaching as a professional development activity.

Children raised by their grandparents are a steadily growing demographic in schools throughout the United States. When parents are unable to care for their children, grandparents sometimes assume the role of primary caregiver. This is especially true when they are faced with the threat of placing their grandchildren in the foster care system. More often than not, these grandparents are not adequately prepared for the challenges of raising children who have lost their parent through death, drug abuse or incarceration and few resources exist to guide elementary school principals to engage this demographic. Regardless of the growing numbers of caregiving grandparents there exists a dearth of research and literature to guide school leaders in effectively engaging these grandparents in school involvement. The purpose of this study was to understand principals’ experiences with grandparents raising grandchildren (GRG), to discover grandparent’s experiences and perspectives on their own experiences in their grandchildren’s schools, and finally, construct theory on how elementary principals create and nurture positive and productive relationships with grandparents raising grandchildren. Analysis of date contributed to the development of propositions that reflect study findings. These propositions contributed to the development of a framework toward theory: Although principals were cognizant of the challenges GRG face, this knowledge did not influence their leadership. As a result, their leadership practices created school environments in which GRGs were effectively engaged in two-way communication but limited decision-making. Furthermore, the schools did not provide a bridge to resources to meet many of the challenges GRG and their families faced.

The goal of this study was to understand how a secondary principal uses a distributed perspective of leadership to support informal teacher leaders (ITLs) to improve classroom technology integration. Using a phenomenological lens, I employed a multi-site case study to inform the research goals. A conceptual framework based on Bandura’s (1977) social learning theory and Wenger’s (1998) communities of practice theory was used to guide the study’s methods and data collection. Data were collected in three phases. At each site, the first phase consisted of a digital survey with only closed-ended questions that was administered to all classroom teachers. The survey was analyzed using social network analysis to identify the ITLs at each school. During the second phase, individual interviews with the ITLs and the principal as well as a follow-up focus group interview with ITLs at each school were conducted. During the final phase of data collection, I observed the ITLs at work to understand how they embodied informal teacher leadership. Analyses of diverse data revealed how a principal influences the nature of informal teacher leadership in a school. Findings revealed that principals establish cultural expectations using teacher voice in leadership decisions, modeling the effective use of education technology, providing in-school and out-of-school leadership opportunities for ITLs, and establishing expectations for all teachers to assume roles of instructional leadership. It was clear in this study that although principals are not directly connected to the informal leading and learning network that occurs in a school, they indirectly influence the informal network by establishing school-wide cultural expectations for informal teacher leadership and by personally interacting with the ITLs.

The goal of this study was to investigate the interaction between professional development and professional capital within international schools in Asia. The researcher employed a multi-site case study to inform the research goals. A conceptual framework based on Hargreaves and Fullan’s (2012) professional capital theory was used to guide the study’s methods and data collection. The data were collected in two phases. The first phase consisted of a digital survey that was distributed to ten international schools associated with the East Asia Regional Council of Schools (EARCOS) and the Office of Overseas Schools (OSS). The survey was analyzed to identify the experiences and perceptions of professional development within international schools. The second phase was comprised of semi-structured interview data from twelve international educators to explore the relationship between professional development and professional capital. The findings of this study helped outline themes of how a professional development fosters professional capital within the international schools. Specifically, international educators use professional development to increase human capital through their experiences to improve personal practice, while developing, retaining, and attracting educators to the international schools. Social capital is impacted through the amount of time international educators allocate to collaborative and networking experiences with other international educators within their field through professional development. By increasing decisional capital, international educators develop expertise with effective professional development guided through the support of mentors by increasing decisional capital. The findings suggest professional development within the international schools studied is connected to an increase in professional capital. The findings also suggest international educators need to maintain a level of autonomy in regard to decision making to continue to increase professional capital within international schools. Suggestions for a refinement of the theory of professional capital leadership include a balanced approach to professional development where teachers use their human capital and school leaders use their social capital collectively to make professional development decisions.

A new ESSA indicator of school quality and student success provides flexibility to broaden a states’ definition of school and student success. Educational research has found school success is in part determined by a school’s climate and should be considered in improvement/reform strategies (Cohen et al., 2009; Thapa et al., 2013). Yet, school climate research is often difficult and time consuming, and employs a variety of conflicting definitions and dimensions, instruments, and empirical approaches to determining school climate. Given these significant limitations with current measures, the purpose of this study was to validate an instrument measuring school climate based on the four most commonly accepted dimensions of school climate, using items adapted from a well-regarded and established theoretical framework to provide an effective measure for educators and researchers. The sample selected for this study was a portion of teachers who indicated teaching 3rd or 8th grade as their primary teaching assignment (n=500) from the larger study sample (n=4974). A Rasch Rating Scale Model was used to evaluate unidimensionality, item fit and difficulty, reliability, and potential differential item functioning on a 23-item school climate survey. Results of the study showed the instrument was not unidimensional and was split into two subdimensions: student-centered and teacher/school support. All items were retained and displayed appropriate fit. Significant differential item functioning (DIF) was found between 3rd and 8th grade teachers on both subdimensions, further suggesting multidimensionality in the scale. Study findings suggest researchers should be mindful of any school climate instrument not validated at the item level for unidimensionality, and that an instrument may perform differently for teachers at different grade levels.
