This dissertation identified ideas and prototypes framing the notion of “preschool” in two types of influential public discourses in Arizona during the 1987-2014: a) editorials, op-editorials, and opinion letters appearing in the Arizona Republic and Arizona Daily Star and b) political documents, including Senate and House Committee Meeting Notes and Comments, Gubernatorial Speeches, Executive Orders, Comments, Proclamations, Memos, and Press Releases. Seventy seven newspaper articles and 43 political documents that substantively addressed debates about preschool in Arizona were identified from an initial pool of 631 documents, of which, 568 were newspaper articles and 63 were political documents.

This dissertation argues little progress can be made in education policy by ignoring the unconscious and automatic levels of thinking, which are not easily dissuaded with rational and factual arguments. Haas and Fischman’s (2010) model for identifying prototypes provided an analytical method to capture the richness and diversity of the educational policy debate about preschool in Arizona. Prototypes captured the values, ideologies and attitudes behind the discourse of “preschool.” Prototypes provide a window into the unconscious thoughts of the authors of the editorials, op-editorials, opinion letters and political documents. This research identified five newspaper prototypes: “Last Resort,” “Community and Family,” “Evidence-Based for At-Risk Children,” “New Knowledge Community,” and “Learner of 21st Century.” It also identified four political political prototypes: ,three of them (“Community and Family,” “Evidence-Based for At-Risk Children,” “Learner of 21st Century”) were aligned with the newspaper prototypes. The fourth prototype was “Arizona Citizen.”

This research concluded that: (1) Multiple “truths” of the concept of “preschool in the newspaper and political documents existed between 1987 and 2014, (2) An inter-relational cross-over existed between the newspaper and political documents effecting the policy debate of preschool, and (3) In less than 30 years, the newspaper and political prototypes narrowed to one. Movement away from the rational policy model, and a broader use of prototypes and discourse analysis in education policymaking, is advocated.

This study is a narrative inquiry into teachers' and instructional coaches' experiences of new curriculum policy implementation at the classroom and district levels. This study took place during the initial year of implementation of the third grade Common Core State Standards in Mathematics (CCSSM). Interviews were conducted with individuals directly involved in policy implementation at the classroom level, including several teachers and the school's instructional coach. Observations of the teachers' instruction and professional practice were also conducted. As an embedded researcher, I used this data to create a series of fictionalized narratives of the initial policy implementation experience. My analysis of the narratives suggests that accountability structures shaped individual's sense-making of the original policy. This sense-making process consequently influenced individuals' actions during implementation by directing them towards certain policy actions and ultimately altered how the policy unfolded in this school and district. In particular, accountability structures directed participants' attention to the technical instructional `forms' of the reform, such as the presence of written responses on assessments and how standards were distributed between grade levels, rather than the overall principled shifts in practice intended by the policy's creators.

This study investigated the current state of the U.S. and Chinese urban middle school math teachers' pedagogical content knowledge (PCK) for the topic of functions. A comparative, descriptive case study was employed to capture the PCK of 23 teachers in Arizona and of 28 teachers in Beijing, regarding their instructional knowledge, understanding of student thinking and curricular knowledge--three key components based on Shulman's conceptualization of PCK--related to functions. Cross-case comparisons were used to analyze the PCK of teacher groups across countries and socio-economic statuses (SES), based on the questionnaire, lesson plan, and interview data.

This study finds that despite cultural differences, teachers are likely to share some commonalities with respect to their instructional decisions, understanding of student thinking and curricular knowledge. These similarities may reflect the convergence in teaching practice in the U.S. and China and the dedication the two countries make in improving math education. This study also finds the cross-country differences and cross-SES differences regarding teachers' PCK. On the one hand, the U.S. and Chinese math teachers of this study tend to diverge in valuing different forms of representations, explaining student misconceptions, and relating functions to other math topics. Teachers' own understanding of functions (and mathematics), standards, and high-stakes testing in each country significantly influence their PCK. On the other hand, teachers from the higher SES schools are more likely to show higher expectations for and stronger confidence in their students' mathematical skills compared to their counterparts from the lower SES schools. Teachers' differential beliefs in students' ability levels significantly contribute to their differences between socio-economic statuses.

This study examined the enactment of a high school district's college-going mission. Treating mission enactment as a case of policy implementation, this study used the lens of complexity theory to understand how system actors and contexts influenced variation and adaptation. Data collection methods included observations, interviews, focus groups, and surveys of various system actors including district staff, principals, counselors, teachers, and students. This study used a mixed methods analytic inductive technique and Social Network Analysis to describe the mission's implementation. Findings reflect that the mission was a vaguely defined value statement; school staff reacted to the mission with limited buy-in and confusion about what it really meant in practice. The mission lacked clear boundaries of what constituted related programs or policies. Consequently, in this site-based district, schools unevenly implemented related programs and policies. School staff wanted more guidance from district staff and clear expectations for mission-related actions. To help meet this need, the district was moving to a more centralized, hierarchical approach. Though they were providing information about the mission, district staff were not providing specific, responsive support to organize school staff's efforts around implementation. District staff were trying to find an approach that both supported schools towards a common vision and provided flexibility for school-level adaptations. Yet, the district had not yet fully formed its position as a facilitator of implementation. Further, as the district lacked a cohesive measurement system, the effectiveness of this initiative was unknown. This study sought to present policy implementation as varied phenomenon, influenced by system actors and conditions. Findings suggest that while policy cannot determine actions, district staff could help create conditions that would support implementation.

Proponents of current educational reform initiatives emphasize strict accountability, the standardization of curriculum and pedagogy and the use of standardized tests to measure student learning and indicate teacher, administrator and school performance. As a result, professional learning communities have emerged as a platform for teachers to collaborate with one another in order to improve their teaching practices, increase student achievement and promote continuous school improvement. The primary purpose of this inquiry was to investigate how teachers respond to working in professional learning communities in which the discourses privilege the practice of regularly comparing evidence of students' learning and results. A second purpose was to raise questions about how the current focus on standardization, assessment and accountability impacts teachers, their interactions and relationships with one another, their teaching practices, and school culture. Participants in this qualitative, ethnographic inquiry included fifteen teachers working within Green School District (a pseudonym). Initial interviews were conducted with all teachers, and responses were categorized in a typology borrowed from Barone (2008). Data analysis involved attending to the behaviors and experiences of these teachers, and the meanings these teachers associated with those behaviors and events. Teachers of GSD responded differently to the various layers of expectations and pressures inherent in the policies and practices in education today. The experiences of the teachers from GSD confirm the body of research that illuminates the challenges and complexity of working in collaborative forms of professional development, situated within the present era of accountability. Looking through lenses privileged by critical theorists, this study examined important intended and unintended consequences inherent in the educational practices of standardization and accountability. The inquiry revealed that a focus on certain "results" and the demand to achieve short terms gains may impede the creation of successful, collaborative, professional learning communities.
