Description
Increasing public criticism of traditional teacher evaluation systems based largely on classroom observations has spurred an unprecedented shift in the debate surrounding educational accountability policies, specifically about the purposes for and measures used to evaluate teachers. In response to growing public demand and associated federal mandates, states have been prompted to design and implement teacher evaluation systems that use increasingly available, statistically complex models (i.e., value-added) intended to isolate and measure the effects of individual teachers on student academic growth over time. The purpose of this study was to examine the perceptions of school administrators and teachers within one of the largest school districts in the state of Arizona with regards to the design and implementation of a federally-supported, state policy-directed teacher evaluation system based on professional practice and value-added measures. While much research has been conducted on teacher evaluation, few studies have examined teacher evaluation systems in context to better understand the standards of effectiveness used by school administrators and teachers to measure system effectiveness. The perceptions of school administrators and teachers, considering their lived experiences as the subjects of the nation's new and improved teacher evaluation systems in context, must be better understood if state and federal policymakers are to also better recognize and understand the consequences (intended and unintended) associated with the design and implementation of these systems in practice.

Description
Lead is a neurotoxin that has been shown to have a long and lasting impact on the brains, bodies, and behaviors of those who are poisoned. It also has a greater presence in communities with high levels of poverty and minority populations. Compounded over time, the effects of lead poisoning, even at low levels of exposure, impact a child's readiness and ability to learn. To investigate the relationship between the risk of lead poisoning, school level academic achievement, and community demographics, three sets of data were combined. The Lead Poisoning Risk Index (LPRI), used to quantify the risk in each census tract of being poisoned by lead, standardized state assessment data for third grade reading and eighth grade math, and census 2000 demographic data were combined to provide information for all Arizona schools and census tracts. When achievement was analyzed at the school level using descriptive, bivariate correlation, and multivariate regression analyses, lead's impact practically disappeared, exposing the powerful effect of poverty and race on achievement. At a school in Arizona, the higher the percentage of students who are poor or Hispanic, African American or Native American, these analyses' predictive models suggest there will be a greater percentage of students who fail the third grade AIMS reading and eighth grade AIMS math tests. If better achievement results are to be realized, work must be done to mitigate the effects of poverty on the lives of students. In order to improve schools, there needs to be an accounting for the context within which schools operate and a focus on improving the neighborhoods and the quality of life for the families of students.

Description
In competitive Taekwondo, Electronic Body Protectors (EBPs) are used to register hits made by players during sparring. EBPs are comprised of three main components: chest guard, foot sock, and headgear. This equipment interacts with each other through the use of magnets, electric sensors, transmitters, and a receiver. The receiver is connected to a computer programmed with software to process signals from the transmitter and determine whether or not a competitor scored a point. The current design of EBPs, however, have numerous shortcomings, including sensing false positives, failing to register hits, costing too much, and relying on human judgment. This thesis will thoroughly delineate the operation of the current EBPs used and discuss research performed in order to eliminate these weaknesses.

Description
School choice reforms such as charter schools, vouchers, open enrollment, and private and public school tax credit donation programs have expanded throughout the United States over the past twenty years. Arizona’s long-standing public school choice system enrolls a higher percentage of public school students in charter schools than any state besides Washington D.C. A growing number of Arizona’s charter schools are managed by for-profit and nonprofit Education Management Organizations (EMOs). Advocates of school choice argue that free-market education approaches will make public schools competitive and nimble as parents’ choices place pressures on schools to improve or close. This, then, improves all schools: public, private, and charter. Critics are concerned that education markets produce segregation along racial and social class lines and inequalities in educational opportunities, because competition favors advantaged parents and children who can access resources. Private and for-profit schools may see it in their interest to exclude students who require more support. School choice programs, then, may further marginalize students who live in poverty, who receive special education services, and English language learners.
We do not fully understand how Arizona’s mature school choice system affects parents and other stakeholders in communities “on the ground.” That is, how are school policies understood and acted out? I used ethnographic methods to document and analyze the social, cultural, and political contexts and perspectives of stakeholders at one district public school and in its surrounding community, including its charter schools. I examined: (a) how stakeholders perceived and engaged with schools; (b) how stakeholders understood school policies, including school choice policies; and (c) what influenced families’ choices.
Findings highlight how most stakeholders supported district public schools. At the same time, some “walked the line” between choices that were good for their individual families and those they believed were good for public schools and society. Stakeholders imagined “community” and “accountability” in a range of ways, and they did not all have equal access to policy knowledge. Pressures related to parental accountability in the education market were apparent as stakeholders struggled to make, and sometimes revisit, their choices, creating a tenuous schooling environment for their families.
