Description
This study examined the intended and unintended consequences associated with the Education Value-Added Assessment System (EVAAS) as perceived and experienced by teachers in the Houston Independent School District (HISD). To evaluate teacher effectiveness, HISD is using EVAAS for high-stakes consequences more than any other district or state in the country. A large-scale electronic survey was used to investigate the model's reliability and validity; to determine whether teachers used the EVAAS data in formative ways as intended; to gather teachers' opinions on EVAAS's claimed benefits and statements; and to understand the unintended consequences that occurred as a result of EVAAS use in HISD. Mixed methods data collection and analyses were used to present the findings in user-friendly ways, particularly when using the words and experiences of the teachers themselves. Results revealed that the reliability of the EVAAS model produced split and inconsistent results among teacher participants, and teachers indicated that students biased the EVAAS results. The majority of teachers did not report similar EVAAS and principal observation scores, reducing the criterion-related validity of both measures of teacher quality. Teachers revealed discrepancies in the distribution of EVAAS reports, the awareness of trainings offered, and among principals' understanding of EVAAS across the district. This resulted in an underwhelming number of teachers who reportedly used EVAAS data for formative purposes. Teachers disagreed with EVAAS marketing claims, implying the majority did not believe EVAAS worked as intended and promoted. Additionally, many unintended consequences associated with the high-stakes use of EVAAS emerged through teachers' responses, which revealed among others that teachers felt heightened pressure and competition, which reduced morale and collaboration, and encouraged cheating or teaching to the test in attempt to raise EVAAS scores. This study is one of the first to investigate how the EVAAS model works in practice and provides a glimpse of whether value-added models might produce desired outcomes and encourage best teacher practices. This is information of which policymakers, researchers, and districts should be aware and consider when implementing the EVAAS, or any value-added model for teacher evaluation, as many of the reported issues are not specific to the EVAAS model.

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
Although U.S. rates of college enrollment among 18-24 year olds have reached historic highs, rates of degree completion have not kept pace. This is especially evident at community colleges, where a disproportionate number of students from groups who, historically, have had low college-completion rates enroll. One way community colleges are attempting to address low completion rates is by implementing institutional interventions intended to increase opportunities for student engagement at their colleges. Utilizing logistic and linear regression analyses, this study focused on community college students, examining the association between participation in institutional support activities and student outcomes, while controlling for specific student characteristics known to impact student success in college. The sample included 746 first-time, full-time, degree-seeking students at a single community college located in the U.S. Southwest. Additional analyses were conducted for the 440 first-time, full-time, degree-seeking students in this sample who placed into at least one developmental education course. Findings indicate that significant associations exist between different types of participation in institutional interventions and various student outcomes: Academic advising was found to be related to increased rates of Fall to Spring and Fall to Fall persistence and, for developmental education students, participation in a student success course was found to be related to an increase in the proportion of course credit hours earned. The results of this study provide evidence that student participation in institutional-level support may relate to increased rates of college persistence and credit hour completion; however, additional inquiry is warranted to inform specific policy and program decision-making at the college and to determine if these findings are generalizable to populations outside of this college setting.

ABSTRACT
Closing the achievement gap between low-income, marginalized, racially, and linguistically diverse students has proven difficult. Research has outlined the effects of funding on student achievement in a manner that focuses the attention on dollars expended, in order overcome barriers to learning. Arizona has long been recognized for its education funding disparity, and its inability to balance fiscal capacity in a manner that serves to improve educational outcomes.
This dissertation examines how Arizona funds its education system. It measures horizontal inequity in a robust manner by examining those fiscal capacity resources directly related to learning and poverty. Recognizing districts with higher concentrations of special needs students will impact fiscal capacity at the district level, this dissertation applies a non-linear analysis to measure how English language learners/ limited English proficient (ELL/ LEP) student proportionality impacts federal and state revenue per pupil, ELL expenditures per pupil, and total expenditures per pupil.
Using the Gini Ratio, McCloone Index, Coefficient of Variation, and Theil inequality index, this dissertation confirms that significant education funding disparity exists across Arizona’s school districts. This dissertation also shows the proportion of English language learners is negatively related to local revenue per pupil, and ELL expenditures per ELL pupil.
Arizona has characteristically funded the public education system inequitably and positioned its students in a manner that stratifies achievement gaps based on wealth. Targeted funding toward ELLs is in no way meaningfully related to the proportion of ELLs in a district. Conceptually the way in which equity is defined, and measured, may require re-evaluation, beyond correlated inputs and outputs. This conceptual re-evaluation of equity must include the decision making process of administrative leaders which influence the quality of those resources related to student learning.

Description
The inherent risk in testing drugs has been hotly debated since the government first started regulating the drug industry in the early 1900s. Who can assume the risks associated with trying new pharmaceuticals is unclear when looked at through society's lens. In the mid twentieth century, the US Food and Drug Administration (FDA) published several guidance documents encouraging researchers to exclude women from early clinical drug research. The motivation to publish those documents and the subsequent guidance documents in which the FDA and other regulatory offices established their standpoints on women in drug research may have been connected to current events at the time. The problem of whether women should be involved in drug research is a question of who can assume risk and who is responsible for disseminating what specific kinds of information. The problem tends to be framed as one that juxtaposes the health of women and fetuses and sets their health as in opposition. That opposition, coupled with the inherent uncertainty in testing drugs, provides for a complex set of issues surrounding consent and access to information.

Description
Social-emotional learning (SEL) methods are beginning to receive global attention in primary school education, yet the dominant emphasis on implementing these curricula is in high-income, urbanized areas. Consequently, the unique features of developing and integrating such methods in middle- or low-income rural areas are unclear. Past studies suggest that students exposed to SEL programs show an increase in academic performance, improved ability to cope with stress, and better attitudes about themselves, others, and school, but these curricula are designed with an urban focus. The purpose of this study was to conduct a needs-based analysis to investigate components specific to a SEL curriculum contextualized to rural primary schools. A promising organization committed to rural educational development is Barefoot College, located in Tilonia, Rajasthan, India. In partnership with Barefoot, we designed an ethnographic study to identify and describe what teachers and school leaders consider the highest needs related to their students' social and emotional education. To do so, we interviewed 14 teachers and school leaders individually or in a focus group to explore their present understanding of “social-emotional learning” and the perception of their students’ social and emotional intelligence. Analysis of this data uncovered common themes among classroom behaviors and prevalent opportunities to address social and emotional well-being among students. These themes translated into the three overarching topics and eight sub-topics explored throughout the curriculum, and these opportunities guided the creation of the 21 modules within it. Through a design-based research methodology, we developed a 40-hour curriculum by implementing its various modules within seven Barefoot classrooms alongside continuous reiteration based on teacher feedback and participant observation. Through this process, we found that student engagement increased during contextualized SEL lessons as opposed to traditional methods. In addition, we found that teachers and students preferred and performed better with an activities-based approach. These findings suggest that rural educators must employ particular teaching strategies when addressing SEL, including localized content and an experiential-learning approach. Teachers reported that as their approach to SEL shifted, they began to unlock the potential to build self-aware, globally-minded students. This study concludes that social and emotional education cannot be treated in a generalized manner, as curriculum development is central to the teaching-learning process.

Description
As of 2019, 30 US states have adopted abortion-specific informed consent laws that require state health departments to develop and disseminate written informational materials to patients seeking an abortion. Abortion is the only medical procedure for which states dictate the content of informed consent counseling. State abortion counseling materials have been criticized for containing inaccurate and misleading information, but overall, informed consent laws for abortion do not often receive national attention. The objective of this project was to determine the importance of informed consent laws to achieving the larger goal of dismantling the right to abortion. I found that informed consent counseling materials in most states contain a full timeline of fetal development, along with information about the risks of abortion, the risks of childbirth, and alternatives to abortion. In addition, informed consent laws for abortion are based on model legislation called the “Women’s Right to Know Act” developed by Americans United for Life (AUL). AUL calls itself the legal architect of the pro-life movement and works to pass laws at the state level that incrementally restrict abortion access so that it gradually becomes more difficult to exercise the right to abortion established by Roe v. Wade. The “Women’s Right to Know Act” is part of a larger package of model legislation called the “Women’s Protection Project,” a cluster of laws that place restrictions on abortion providers, purportedly to protect women, but actually to decrease abortion access. “Women’s Right to Know” counseling laws do not directly deny access to abortion, but they do reinforce key ideas important to the anti-abortion movement, like the concept of fetal personhood, distrust in medical professionals, the belief that pregnant people cannot be fully autonomous individuals, and the belief that abortion is not an ordinary medical procedure and requires special government oversight. “Women’s Right to Know” laws use the language of informed consent and the purported goal of protecting women to legitimize those ideas, and in doing so, they significantly undermine the right to abortion. The threat to abortion rights posed by laws like the “Women’s Right to Know” laws indicates the need to reevaluate and strengthen our ethical defense of the right to abortion.

Description
Turbidity is a known problem for UV water treatment systems as suspended particles can shield contaminants from the UV radiation. UV systems that utilize a reflective radiation chamber may be able to decrease the impact of turbidity on the efficacy of the system. The purpose of this study was to determine how kaolin clay and gram flour turbidity affects inactivation of Escherichia coli (E. coli) when using a UV system with a reflective chamber. Both sources of turbidity were shown to reduce the inactivation of E. coli with increasing concentrations. Overall, it was shown that increasing kaolin clay turbidity had a consistent effect on reducing UV inactivation across UV doses. Log inactivation was reduced by 1.48 log for the low UV dose and it was reduced by at least 1.31 log for the low UV dose. Gram flour had a similar effect to the clay at the lower UV dose, reducing log inactivation by 1.58 log. At the high UV dose, there was no change in UV inactivation with an increase in turbidity. In conclusion, turbidity has a significant impact on the efficacy of UV disinfection. Therefore, removing turbidity from water is an essential process to enhance UV efficiency for the disinfection of microbial pathogens.

Description
Aquatic macroinvertebrates are important for many ecological processes within river ecosystems and, as a result, their abundance and diversity are considered indicators of water quality and ecosystem health. Macroinvertebrates can be classified into functional feeding groups (FFG) based on morphological-behavioral adaptations. FFG ratios can shift due to changes in normal disturbance patterns, such as changes in precipitation, and from human impact. Due to their increased sensitivity to environmental changes, it has become more important to protect and monitor aquatic and riparian communities in arid regions as climate change continues to intensify. Therefore, the diversity and richness of macroinvertebrate FFGs before and after monsoon and winter storm seasons were analyzed to determine the effect of flow-related disturbances. Ecosystem size was also considered, as watershed area has been shown to affect macroinvertebrate diversity. There was no strong support for flow-related disturbance or ecosystem size on macroinvertebrate diversity and richness. This may indicate a need to explore other parameters of macroinvertebrate community assembly. Establishing how disturbance affects aquatic macroinvertebrate communities will provide a key understanding as to what the stream communities will look like in the future, as anthropogenic impacts continue to affect more vulnerable ecosystems.
