Description
In this dissertation I attempt to find elements of education and curricular perspective in the Qur'an. I argue that there is little research in the field of curriculum instruction that discusses the Qur'an's educational aspects and, as a result, much ignorance of the Qur'an's material that deals with education and curricular perspective in the Qur'an. Researchers may find many materials that deal with reading, memorizing, and reciting the Qur'an, along with references that deal with science and math in the Qur'an. Therefore, this dissertation answers the question: What curriculum exists within the Quran? This dissertation is divided into five chapters exploring various aspects of the curriculum. The word "curriculum" is used in one chapter to mean developing the person as a whole in all aspects of life whether spiritual, social, or mental while in the other chapter curriculum is used to refer to methods of instruction. I concluded that curriculum in the Qur'an uses different methods of instructions to develop the individual as a whole in all aspects of life while granting freedom of choice.

Legislative changes and discussions about the United States falling further and further behind other nations in science, technology, engineering, and math (STEM) achievement are growing. As they grow, STEM instruction in elementary school has earned its place as a national area of interest in education. In the case of Ivory School District, teachers are being asked to radically change their daily practices by consistently implementing inquiry-based STEM experiences in their classrooms. As such, teachers are being asked to scale a divide between the district expectations and their knowledge and experience. Many fourth grade educators are teachers who have been trained as generalists and typically do not have specific background or experience in the philosophy, instructional strategies, or content associated with STEM. Using a prototype approach, this study aims to understand how such teachers conceptualize STEM instruction and the relationship between their experience and conceptions.

Description
Examining the elements of the hidden curriculum in theatre education allows theatre educators the opportunity to reflect on their own pedagogy and its effects on the learner. The hidden curriculum refers to the unspoken or implicit values, norms, and beliefs that are transmitted through tacit messages. When the hidden curriculum remains veiled, the impact on the learner's education and socialization process can perpetuate gender, race, and class inequalities. In order to understand how the hidden curriculum manifests itself in theatre classrooms, we have to look at schools as "agents of legitimation, organized to produce and reproduce the dominant categories, values, and social relationships necessary for the maintenance of the larger society" (Giroux, 1983, p. 72). This qualitative study examined the hidden curriculum in theatre at the secondary level and looked at theatre teachers' pedagogy in reproducing elements of the hidden curriculum. Interviews, naturalistic observation, and a researcher reflective journal were employed in the data collection process to better understand: a) the elements of hidden curriculum that appear in theatre education at the secondary level, b) how the pedagogical practices of theatre teachers support societal structures, and c) how the hidden curriculum in theatre reinforces gender, race, and social class distinctions. Data were then coded and analyzed to find emergent themes. Multiple theoretical perspectives serve as a conceptual framework for understanding the hidden curriculum, and provide a neglected perspective of the hidden curriculum in theatre education. The theatre classroom provides a unique space to view hidden curriculum and can be viewed as a unique agent of social change. Themes related to the first research question emerged as: a) privileges for older students, b) school rules, c) respect for authority, d) acceptance of repetitive tasks, and c) punctuality. Themes related to the second research question emerged as: a) practices, b) procedures, c) rules, d) relationships, and e) structures. Finally, themes related to the third question emerged as: a) reinforcement of social inequality, b) perpetuation of class structure, and c) acceptance of social destiny. The discussion looks at the functions of theatre pedagogy in the reproduction of class, inequality, and institutionalized cultural norms.

Description
The presence of language minority students in American schools is a growing phenomenon in present-day times. In the year 2008, almost 11 million school-age children spoke a language other than English at home. Educational language policy is largely influenced by the attitudes that society holds regarding the presence of language minority speakers in the community. One of the sources of these attitudes is the written press. This research aimed at identifying and analyzing the ideologies that newspapers display in connection with language minority speakers. The underlying assumption of the study was that the English language occupies a dominant position in society, thus creating a power struggle in which speakers of other languages are disenfranchised. Using critical theory as the theoretical framework enabled the study to identify and oppose the ideologies that may reproduce and perpetuate social inequalities. The methodological approach used was critical discourse analysis (CDA) which aligns with the main tenets of critical theory, among them the need to uncover hidden ideologies. The analysis of articles from English-language (The Arizona Republic and the East Valley Tribune) and Spanish-language (La Prensa Hispana) newspapers allowed for the identification of the ideologies of the written press in connection to two main hypothetical constructs: education and immigration. The analysis of the results revealed that the three newspapers of the study held specific ideologies on issues related to the education of language minority students and immigration. Whereas the East Valley Tribune showed an overarching ideology connected to the opposition of immigrant students in schools, the hegemonic position of theEnglish language, and a belligerent stance toward the immigrant community, The Arizona Republic showed a favorable attitude to both English Language Learners and immigrants, based on reasons mainly related to the economic interest of the state of Arizona. La Prensa Hispana, on the other hand, showed ideologies favorable to the immigrant community based on humanitarianism. In summary, the results confirm that newspapers hold specific ideologies and that these ideologies are reflected in the content and the manner of their information to the public.

Description
ABSTRACT High numbers of dropouts can be found throughout the country, but research has shown the problem to be most prevalent in minority communities. Although the majority of dropouts were Anglo, the highest event dropout rates were found among American Indians, Hispanics and African Americans. This descriptive study investigated how students negotiate school structure, social supports, and cultural identity to gain an insider or "emic" perspective on youth decision-making regarding whether to drop out or remain in school. Research was conducted in a suburban school district with a high school population of over 10,000 students in grades 9 through 12. Student selection was based on criteria developed through an analysis of district data of students that had dropped out of school over a three-year period from the 2006-2007 to 2008-2009 school years. In-depth semi-structured interviews were conducted with seven participants of high school age. These participants were placed in one of three sample groups that fit the dropout profile. These groups were (1) students currently attending high school, (2) students who dropped out prior to completing graduation requirements, and (3) students who had graduated. The findings in this study will benefit the educational community as it relates to K-12 education and students leaving school (dropping out). Educators and administrators will be able to evaluate the findings of the study to review current practices and policies within their organization. The data will also give administrators the opportunity to develop and implement programs that can assist students in staying in school.

Description
Participatory Budgeting (PB) can create changes within individuals and between them and their community. PB processes allow people to determine how to spend a portion of a particular budget (in the case of School PB, a portion of the school budget). These processes help address the underrepresentation of youth in the realm of civics.
I spent time with the steering committee and teacher coordinator of school PB in Carson Junior High to explore the impact of school PB on students’ knowledge, skills, attitudes and practices in relation to civic engagement. In the study I used quantitative and qualitative components. The participants were unique in that they all had prior experience in civic engagement programs in Carson Junior High that were organized by the teacher coordinator of school PB.
The main findings suggest that the participants reported a significant amount of learning in civic knowledge. In comparison, their overall perceived growth in attitudes, practices and skills were much lower. School PB helped the participants in the steering committee to grow in different ways than their other civic engagement programs by providing them with knowledge about budgets, their school’s mechanisms and other students within their school. They also became more familiar with the democratic process of voting and more comfortable with public speaking and presenting.
Recommendations for future research on this process include compiling quantitative and qualitative data from a larger sample consisting of students who had prior civic engagement experience and students who didn’t, and students with different ethnicities from different grades. Another recommendation for future research is to conduct a longitudinal study following school PB participants to high school and beyond to explore long-term impacts.

Description
In nature, it is commonly observed that animals and birds perform movement-based thermoregulation activities to regulate their body temperatures. For example, flapping of elephant ears or plumage fluffing in birds. Taking inspiration from nature and to explore the possibilities of such heat transfer enhancements, augmentation of heat transfer rates induced by the vibration of solid and well as novel flexible pinned heatsinks were studied in this research project. Enhancement of natural convection has always been very important in improving the performance of the cooling mechanisms. In this research, flexible heatsinks were developed and they were characterized based on natural convection cooling with moderately vibrating conditions. The vibration of heated surfaces such as motor surfaces, condenser surfaces, robotic arms and exoskeletons led to the motivation of the development of heat sinks having flexible fins with an improved heat transfer capacity. The performance of an inflexible, solid copper pin fin heat sink was considered as the baseline, current industry standard for the thermal performance. It is expected to obtain maximum convective heat transfer at the resonance frequency of the flexible pin fins. Current experimental results with fixed input frequency and varying amplitudes indicate that the vibration provides a moderate improvement in convective heat transfer, however, the flexibility of fins had negligible effects.

Description
Solar energy has become one of the most popular renewable energy in human’s life because of its abundance and environment friendliness. To achieve high solar energy conversion efficiency, it usually requires surfaces to absorb selectivity within one spectral range of interest and reflect strongly over the rest of the spectrum. An economic method is always desired to fabricate spectrally selective surfaces with improved energy conversion efficiency. Colloidal lithography is a recently emerged way of nanofabrication, which has advantages of low-cost and easy operation.
In this thesis, aluminum metasurface structures are proposed based on colloidal lithography method. High Frequency Structure Simulator is used to numerically study optical properties and design the aluminum metasurfaces with selective absorption. Simulation results show that proposed aluminum metasurface structure on aluminum oxide thin film and aluminum substrate has a major reflectance dip, whose wavelength is tunable within the near-infrared and visible spectrum with metasurface size. As the metasurface is opaque due to aluminum film, it indicates strong wavelength-selective optical absorption, which is due to the magnetic resonance between the top metasurface and bottom Al film within the aluminum oxide layer.
The proposed sample is fabricated based on colloidal lithography method. Monolayer polystyrene particles of 500 nm are successfully prepared and transferred onto silicon substrate. Scanning electron microscope is used to check the surface topography. Aluminum thin film with 20-nm or 50-nm thickness is then deposited on the sample. After monolayer particles are removed, optical properties of samples are measured by micro-scale optical reflectance and transmittance microscope. Measured and simulated reflectance of these samples do not have frequency selective properties and is not sensitive to defects. The next step is to fabricate the Al metasurface on Al_2 O_3 and Al films to experimentally demonstrate the selective absorption predicted from the numerical simulation.

Description
The thermal conductivity of cadmium sulfide (CdS) colloidal nanocrystals (NCs) and magic-sized clusters (MSCs) have been investigated in this work. It is well documented in the literature that the thermal conductivity of colloidal nanocrystal assemblies decreases as diameter decreases. However, the extrapolation of this size dependence does not apply to magic-sized clusters. Magic-sized clusters have an anomalously high thermal conductivity relative to the extrapolated size-dependence trend line for the colloidal nanocrystals. This anomalously high thermal conductivity could probably result from the monodispersity of magic-sized clusters. To support this conjecture, a method of deliberately eliminating the monodispersity of MSCs by mixing them with colloidal nanocrystals was performed. Experiment results showed that mixtures of nanocrystals and MSCs have a lower thermal conductivity that falls approximately on the extrapolated trendline for colloidal nanocrystal thermal conductivity as a function of size.

Description
Dehumidifiers are ubiquitous and essential household appliances in many parts of the world. They are used extensively in tropical and sub-tropical environments to lower humidity in living spaces, where high ambient humidity can lead to numerous negative health effects from mild physical discomfort to more serious conditions such as mold build up in structures and dangerous illnesses in humans. Most common dehumidifiers are based on conventional mechanical refrigeration cycles, where the effects of condensation heat transfer play a critical role in their effectiveness. In these devices, humid ambient air flows over a cold evaporator, which lowers the temperature of the humid ambient air below its dew point temperature and therefore decreases its water content by causing liquid water condensation on the evaporator surface. The rate at which humidity can be extracted from the ambient air is governed in part by how quickly the evaporator can shed the condensed droplets. Recent advances in soft, stretchable, thermally enhanced (through the addition of liquid metals) silicone tubing offer the potential to use these stretchable tubes in place of conventional copper pipe for applications such as dehumidification. Copper is a common material choice for dehumidifier evaporator tubing owing to its ubiquity and its high thermal conductivity, but it has several thermal downsides. Specifically, copper tubes remain static and typically rely on gravity alone to remove water droplets when they reach a sufficient mass. Additionally, copper’s naturally hydrophilic surface promotes film-wise condensation, which is substantially less effective than dropwise condensation. In contrast to copper, thermally enhanced soft stretchable tubes have naturally hydrophobic surfaces that promote the more effective dropwise condensation mode and a soft surface that offers higher nucleation density. However, soft surfaces also increase droplet pinning, which inhibits their departure. This work experimentally explores the effects of periodic axial stretching and retraction of soft tubing internally cooled with water on droplet condensation dynamics on its exterior surface. Results are discussed in terms of overall system thermal performance and real-time condensation imaging. An overall null result is discovered, and recommendations for future experiments are made.
