Description
A primary goal in computer science is to develop autonomous systems. Usually, we provide computers with tasks and rules for completing those tasks, but what if we could extend this type of system to physical technology as well? In the field of programmable matter, researchers are tasked with developing synthetic materials that can change their physical properties \u2014 such as color, density, and even shape \u2014 based on predefined rules or continuous, autonomous collection of input. In this research, we are most interested in particles that can perform computations, bond with other particles, and move. In this paper, we provide a theoretical particle model that can be used to simulate the performance of such physical particle systems, as well as an algorithm to perform expansion, wherein these particles can be used to enclose spaces or even objects.

Description
Challenging project-based learning, this 3-part thesis analyzes the current environment of business and university relationships, examines an experimental course at W.P. Carey and proposes a unique, execution-based teaching strategy. The outcome is a sustainable and mutually beneficial relationship between business and universities that allows each to operate at its maximum potential while bridging the gap for students between classroom theory and its application in the real world of business.

Description
Covering subsequences with sets of permutations arises in many applications, including event-sequence testing. Given a set of subsequences to cover, one is often interested in knowing the fewest number of permutations required to cover each subsequence, and in finding an explicit construction of such a set of permutations that has size close to or equal to the minimum possible. The construction of such permutation coverings has proven to be computationally difficult. While many examples for permutations of small length have been found, and strong asymptotic behavior is known, there are few explicit constructions for permutations of intermediate lengths. Most of these are generated from scratch using greedy algorithms. We explore a different approach here. Starting with a set of permutations with the desired coverage properties, we compute local changes to individual permutations that retain the total coverage of the set. By choosing these local changes so as to make one permutation less "essential" in maintaining the coverage of the set, our method attempts to make a permutation completely non-essential, so it can be removed without sacrificing total coverage. We develop a post-optimization method to do this and present results on sequence covering arrays and other types of permutation covering problems demonstrating that it is surprisingly effective.

Description
Nations have a vital interest in creating a citizenry with certain attributes and beliefs and, since education contributes to the formation of children's national identity, government authorities can influence educational curricula to construct their ideal citizen. In this thesis, I study the educational systems of Pakistan and Arizona and explore the historical and conceptual origins of these entities' manipulation of curricula to construct a particular kind of citizen. I argue that an examination of the ethnic studies debate in Tucson, Arizona, in conjunction with Pakistan's history education policy, will illustrate that the educational systems in both these sites are developed to advance the interests of governing authorities. Resource material demonstrates that both educational systems endorse specific accounts of history, omitting information, perspectives, and beliefs. Eliminating or reimagining certain narratives of history alienates some students from identifying as citizens of the state, particularly when contributions of their ethnic, cultural, or religious groups are not included in the country's textbooks.

Description
This thesis investigates the environment of support for reclassified English Language Learners (RCELLs) in Arizona schools. Arizona English Language Learner (ELL) policy and pedagogy have been the subjects of research nationwide; many studies demonstrate that ELLs struggle before, during and after participating in Arizona ELL programs (Lillie et al. 2012; Roa 2012; Garcia, Lawton & de Figuieredo 2012; Office of Civil Rights 2012). Despite evidence that the achievement gap between RCELLs and mainstream students is not closing, little information is available about additional language support that RCELLs might receive in mainstream classrooms. This thesis addresses that void of information through: 1) A literature review of the framework of RCELL support, as outlined by the Arizona Department of Education and relevant studies, and 2) a study of teacher and principal opinion about support components for RCELLs and whether such support is adequate. Study findings present that teachers and principals generally believe RCELLs are well-supported, in terms of both the availability and quality of study-defined support components. Yet there is only weak consensus among teachers that support components are adequate. Additionally, teachers' knowledgeability related to important RCELL support components is low, undermining the reliability of teacher responses. The disconnect between participants' optimistic perceptions of support and the external evidence of low RCELL achievement is rationalized by two conjectures. The first is that teachers are not knowledgeable about RCELL support components and cannot accurately gauge the quality of such support. The second is that existing support components are effective at assisting RCELLs with English learning but are not sufficient to close RCELL academic content achievement gaps.

Bots tamper with social media networks by artificially inflating the popularity of certain topics. In this paper, we define what a bot is, we detail different motivations for bots, we describe previous work in bot detection and observation, and then we perform bot detection of our own. For our bot detection, we are interested in bots on Twitter that tweet Arabic extremist-like phrases. A testing dataset is collected using the honeypot method, and five different heuristics are measured for their effectiveness in detecting bots. The model underperformed, but we have laid the ground-work for a vastly untapped focus on bot detection: extremist ideal diffusion through bots.

This thesis explores my experience in teaching a high school music class through composition. I detail pedagogical approaches that helped to shape my lesson planning including constructivism, informal learning, and project based learning. The music education theory is put into action in a real high school setting and I explain what happened: what worked, what didn't, and what can we learn from this?

Description
"Improving Life Outcomes for Children in Arizona: Educational Social Impact Bond" is a creative project that is structured as a pitch to the Arizona Department of Education to consider social impact bonds as a way to fund pilot education programs. The pitch begins with a brief overview of the umbrella of impact investing, and then a focus on social impact bonds, an area of impact investing. A profile of Arizona's current educational rankings along with statistics are then presented, highlighting the need for an educational social impact bond to help increase achievement. The pitch then starts to focus particularly on high school drop outs and how by funding early childhood education the chances of a child graduating high school increase. An overview of existing early education social impact bonds that are enacted are then presented, followed by a possible structure for an early education social impact bond in Arizona. An analysis of the possible lifetime cost savings of investing in early childhood education are then presented, that are as a result of decreasing the amount of high school drop outs. Lastly, is a brief side-by-side comparison of the Arizona structure to the precedent social impact bonds.

Description
There is still a major underrepresentation of females in STEM fields, with many girls beginning to lose interest as early as middle school. This is due to a variety of factors including lack of role models, stereotypes, ineffective teaching methods, and peer influence. A popular way to increase female interest is through day camps and other programs where girls complete a variety of activities related to science and engineering. These activities are usually designed around problem-based learning, a student-lead approach to teaching that requires students to work collaboratively and use background knowledge to solve some sort of given problem. In this project, a day camp for middle school girls was created and implemented to increase student interest in STEM through three problem-based learning activities. By analyzing survey data, it was concluded that the camp was successful in increasing interest and changing participants' attitudes towards science. This approach to learning could be applied to other subject areas, including mathematics, to increase the interest of both male and female students at the secondary level.

Description
To supplement lectures, various resources are available to students; however, little research has been done to look systematically at which resources studies find most useful and the frequency at which they are used. We have conducted a preliminary study looking at various resources available in an introductory material science course over four semesters using a custom survey called the Student Resource Value Survey (SRVS). More specifically, the SRVS was administered before each test to determine which resources students use to do well on exams. Additionally, over the course of the semester, which resources students used changed. For instance, study resources for exams including the use of homework problems decreased from 81% to 50%, the utilization of teaching assistant for exam studying increased from 25% to 80%, the use of in class Muddiest Points for exam study increased form 28% to 70%, old exams and quizzes only slightly increased for exam study ranging from 78% to 87%, and the use of drop-in tutoring services provided to students at no charge decreased from 25% to 17%. The data suggest that students thought highly of peer interactions by using those resources more than tutoring centers. To date, no research has been completed looking at courses at the department level or a different discipline. To this end, we adapted the SRVS administered in material science to investigate resource use in thirteen biomedical engineering (BME) courses. Here, we assess the following research question: "From a variety of resources, which do biomedical engineering students feel addresses difficult concept areas, prepares them for examinations, and helps in computer-aided design (CAD) and programming the most and with what frequency?" The resources considered include teaching assistants, classroom notes, prior exams, homework problems, Muddiest Points, office hours, tutoring centers, group study, and the course textbook. Results varied across the four topical areas: exam study, difficult concept areas, CAD software, and math-based programming. When preparing for exams and struggling with a learning concept, the most used and useful resources were: 1) homework problems, 2) class notes and 3) group studying. When working on math-based programming (Matlab and Mathcad) as well as computer-aided design, the most used and useful resources were: 1) group studying, 2) engineering tutoring center, and 3) undergraduate teaching assistants. Concerning learning concepts and exams in the BME department, homework problems and class notes were considered some of the highest-ranking resources for both frequency and usefulness. When comparing to the pilot study in MSE, both BME and MSE students tend to highly favor peer mentors and old exams as a means of studying for exams at the end of the semester1. Because the MSE course only considered exams, we cannot make any comparisons to BME data concerning programming and CAD. This analysis has highlighted potential resources that are universally beneficial, such as the use of peer work, i.e. group studying, engineering tutoring center, and teaching assistants; however, we see differences by both discipline and topical area thereby highlighting the need to determine important resources on a class-by-class basis as well.
