Description
ABSTRACT A review of studies selected from the Educational Resource Information Center (ERIC) covering the years 1985 through 2011 revealed three key evaluation components to analyze within a comprehensive teacher evaluation program: (a) designing, planning, and implementing instruction; (b) learning environments; and (c) parent and peer surveys. In this dissertation, these three components are investigated in the context of two research questions: 1. What is the relationship, if any, between comprehensive teacher evaluation scores and student standardized test scores? 2. How do teachers and administrators experience the comprehensive evaluation process and how do they use their experiences to inform instruction? The methodology for the study included a mixed-method case study at a charter school located in a middle-class neighborhood within a large metropolitan area of the southwestern United States, which included a comparison of teachers' average evaluation scores in the areas of instruction and environment, peer survey scores, parent survey scores, and students' standardized test (SST) benchmark scores over a two-year period as the quantitative data for the study. I also completed in-depth interviews with classroom teachers, mentor teachers, the master teacher, and the school principal; I used these interviews for the qualitative portion of my study. All three teachers had similar evaluation scores; however, when comparing student scores among the teachers, differences were evident. While no direct correlations between student achievement data and teacher evaluation scores are possible, the qualitative data suggest that there were variations among the teachers and administrators in how they experienced or "bought into" the comprehensive teacher evaluation, but they all used evaluation information to inform their instruction. This dissertation contributes to current research by suggesting that comprehensive teacher evaluation has the potential to change teachers' and principals' perceptions of teacher evaluation as inefficient and unproductive to a system that can enhance instruction and ultimately improve student achievement.

Description
Choropleth maps are a common form of online cartographic visualization. They reveal patterns in spatial distributions of a variable by associating colors with data values measured at areal units. Although this capability of pattern revelation has popularized the use of choropleth maps, existing methods for their online delivery are limited in supporting dynamic map generation from large areal data. This limitation has become increasingly problematic in online choropleth mapping as access to small area statistics, such as high-resolution census data and real-time aggregates of geospatial data streams, has never been easier due to advances in geospatial web technologies. The current literature shows that the challenge of large areal data can be mitigated through tiled maps where pre-processed map data are hierarchically partitioned into tiny rectangular images or map chunks for efficient data transmission. Various approaches have emerged lately to enable this tile-based choropleth mapping, yet little empirical evidence exists on their ability to handle spatial data with large numbers of areal units, thus complicating technical decision making in the development of online choropleth mapping applications. To fill this knowledge gap, this dissertation study conducts a scalability evaluation of three tile-based methods discussed in the literature: raster, scalable vector graphics (SVG), and HTML5 Canvas. For the evaluation, the study develops two test applications, generates map tiles from five different boundaries of the United States, and measures the response times of the applications under multiple test operations. While specific to the experimental setups of the study, the evaluation results show that the raster method scales better across various types of user interaction than the other methods. Empirical evidence also points to the superior scalability of Canvas to SVG in dynamic rendering of vector tiles, but not necessarily for partial updates of the tiles. These findings indicate that the raster method is better suited for dynamic choropleth rendering from large areal data, while Canvas would be more suitable than SVG when such rendering frequently involves complete updates of vector shapes.

Description
With changes in federal legislation and the proposed reauthorization of The Elementary and Secondary Education Act, school administrators are held to high standards in an attempt to improve achievement for all students. They no longer just manage their schools but must now be instructional leaders charged with observing and conferencing with teachers, leading professional development aligned to data, and measuring results. Classroom walkthroughs have become a way of assisting with these tasks while supporting the mission of each school. The purpose of this research was to describe how walkthroughs operate in practice and how they were experienced by school administration, teacher leaders, and teachers at two schools within the same suburban district. Interviews illustrated that experiences were varied using the classroom walkthrough protocol. Continued professional development needed to occur with administrators and teachers. Participants shared their thoughts on implementation and usage, as well as made recommendations to schools and/or districts considering implementing classroom walkthroughs. Results also indicated a great deal of attention paid to the collection of data within the schools but there was less consensus on the analysis and use of the collected data. There was also confusion with teachers as to the vision, purpose, and goals of using classroom walkthroughs. Changes in leadership during the five years since implementation and young administrators, who were relatively new in their positions, helped shape school experiences. Recommendations to schools and/or districts considering implementation focused on support from the district office, a need for help with data collection and analysis, and a clear vision for the use of the protocol. Interviewees mentioned it would benefit districts and schools to develop a shared vocabulary for instructional engagement, alignment, and rigor, as well as a focus for professional development. They also shared the view that calibration conferences and conversations, centered on instruction, provided a focus for teaching and learning within a school and/or district.

Description
In the First Innovations Initiative at Arizona State University students are exposed to the culture of innovation and the entrepreneurial process through two courses situated intentionally within an American Indian sustainability context. In this action research dissertation, a summer field practicum was designed and implemented to complement the two in-classroom course offerings. The first implementation of the new summer field practicum was documented for the two participating students. A survey and focus group were conducted to evaluate the spring 2011 classroom course and, separately, to evaluate the summer field practicum. Students in the spring 2011 course and summer field practicum reported that they were stimulated to think more innovatively, gained interest in the subject area and entrepreneurial/innovation processes, and improved their skills related to public speaking, networking, problem solving and research. The summer practicum participants reported larger increases in confidence in creating, planning and implementing a sustainable entrepreneurship venture, compared with the reports of the spring in-classroom participants. Additionally, differences favoring the summer practicum students were found in reported sense of community and individualism in support of entrepreneurship and innovation. The study results are being used to revamp both the in-classroom and field practicum experience for the benefit of future participants. Specifically, the American Indian perspective will be more fully embedded in each class session, contemporary timely articles and issues will be sought out and discussed in class, and the practicum experience will be further developed with additional student participants and site organizations sought. Additionally, the trans-disciplinary team approach will continue, with additional professional development opportunities provided for current team members and the addition of new instructional team members.

Description
There is a serious need for early childhood intervention practices for children who are living at or below the poverty line. Since 1965 Head Start has provided a federally funded, free preschool program for children in this population. The City of Phoenix Head Start program consists of nine delegate agencies, seven of which reside in school districts. These agencies are currently not conducting local longitudinal evaluations of their preschool graduates. The purpose of this study was to recommend initial steps the City of Phoenix grantee and the delegate agencies can take to begin a longitudinal evaluation process of their Head Start programs. Seven City of Phoenix Head Start agency directors were interviewed. These interviews provided information about the attitudes of the directors when considering longitudinal evaluations and how Head Start already evaluates their programs through internal assessments. The researcher also took notes on the Third Grade Follow-Up to the Head Start Executive Summary in order to make recommendations to the City of Phoenix Head Start programs about the best practices for longitudinal student evaluations.

The purpose of this thesis is to evaluate a tool used for assessing games for design features that teach players a basic understanding of systems. In order to prepare for my evaluation of both the games and the rubric, I researched multiple articles about the effectiveness of games in teaching, the concepts of systems thinking, and the importance of systems thinking. I evaluated five different games, following the rubric for whether the five games met the specific criteria laid out in each section and suggested improvements for how the games can meet any criteria that they fell short in. I then evaluated the rubric itself for ease of use, clarity, and effectiveness and suggested improvements on how to make the tool more clear and understandable. I conclude that the tool is indeed useful and does achieve its purpose of helping game designers and developers understand the criteria needed to teach a basic understanding of systems, but the rubric could be improved in order to make it more useable.

Description
This is an evaluation of the Sandra Day O'Connor College of Law learning environment project which involved 120 participants (32 faculty and 88 students). In 2016, the Sandra Day O'Connor College of Law moved their main building to the newly built Beus Center for Law and Society building at the downtown Phoenix campus in order to bring the law students and faculty closer to the legal community that is present in downtown Phoenix. Prior to this move surveys regarding the Tempe campus were administered to the law students and faculty along with classroom observations and focus groups in order to conduct an evaluation of the environment. This evaluation examines the following six areas about the Tempe campus: the physical classroom environment; the instructional strategies used by instructors in the classroom; technology utilized in the classroom; frequency of technical difficulties by the instructor; and interactions between faculty, students, and the legal community. This evaluation only analyzed the quantitative data that was provided from the survey questions and not the qualitative data from classroom observations and focus groups. Within this evaluation is an explanation of the project that was conducted in part with the Sandra Day O'Connor College of Law and an overview of the participants involved in this evaluation. Additionally, this report will describe the methodology that was used to conduct the evaluation. Lastly, this evaluation includes the findings based off of the survey given to the evaluation participants and the recommendation for the new Beus Center for Law and Society based on the findings of the evaluation.

Description
In natural language processing, language models have achieved remarkable success over the last few years. The Transformers are at the core of most of these models. Their success can be mainly attributed to an enormous amount of curated data they are trained on. Even though such language models are trained on massive curated data, they often need specific extracted knowledge to understand better and reason. This is because often relevant knowledge may be implicit or missing, which hampers machine reasoning. Apart from that, manual knowledge curation is time-consuming and erroneous. Hence, finding fast and effective methods to extract such knowledge from data is important for improving language models. This leads to finding ideal ways to utilize such knowledge by incorporating them into language models. Successful knowledge extraction and integration lead to an important question of knowledge evaluation of such models by developing tools or introducing challenging test suites to learn about their limitations and improve them further. So to improve the transformer-based models, understanding the role of knowledge becomes important. In the pursuit to improve language models with knowledge, in this dissertation I study three broad research directions spanning across the natural language, biomedical and cybersecurity domains: (1) Knowledge Extraction (KX) - How can transformer-based language models be leveraged to extract knowledge from data? (2) Knowledge Integration (KI) - How can such specific knowledge be used to improve such models? (3) Knowledge Evaluation (KE) - How can language models be evaluated for specific skills and understand their limitations?
I propose methods to extract explicit textual, implicit structural, missing textual, and missing structural knowledge from natural language and binary programs using transformer-based language models. I develop ways to improve the language model’s multi-step and commonsense reasoning abilities using external knowledge. Finally, I develop challenging datasets which assess their numerical reasoning skills in both in-domain and out-of-domain settings.

Description
The goal of the first study was to characterize the Miocene arkosic conglomerate in the Goldfield Mountains to determine the paleocurrent direction and source of the cobbles. This conglomerate is tilted to the northeast and unconformably overlies Proterozoic basement. Imbrication measurements are scattered but suggest the direction of paleoflow was toward the northwest and northeast, which suggests the cobbles were sourced from the southeast and southwest. The abundance of Dripping Spring Quartzite and the presence of Barnes Conglomerate in the cobbles, suggests an Apache Group source. In addition, south-southeast of the map area, there are several rock units composed of the same material as cobbles within the arkosic conglomerate. The arkosic conglomerate was likely deposited during onset of mid-Cenozoic extension, where the resulting highlands could provide a nearby source for the cobbles. This nearby source is interpreted to be south-southeast of the study area. A second study examined the effectiveness of course reform conducted on an introductory undergraduate course sequence. Questions of this study included: (1) How does the curriculum cater to a student population with diverse goals? (2) How do reformed courses add educational value as perceived by the student? (3) How does the redesigned curriculum and the instructional strategies, as implemented, address the goals of the reform?
The curriculum addressed the goals of the reform by (1) creating more opportunities for students to gain the skills relevant to their future goals, (2) having students utilize big data to make observations, interpretations, and predictions, (3) engaging students in scientific collaboration through group work and discussion, (4) giving students the opportunity to utilize computer programs that apply across various subjects and fields (i.e. Excel, MS Word, ArcGIS), and (5) requiring students to conduct original research to solve a problem and present their results orally and in written form. These redesign efforts were successful in meeting the objectives, and majority of the student participants reported one or more of the reformed experiences were valuable to their education and future goals. An understanding of teaching methods and educational values held by undergraduate students within the School of Earth and Space Exploration can be adapted and applied across subjects.
