Background: Childhood obesity is one of the most serious public health concerns in the United States and has been associated with low levels of physical activity. Schools are ideal physical activity promotion sites but school physical activity opportunities have decreased due the increased focus on academic performance. Before-school programs provide a good opportunity for children to engage in physical activity as well as improve their readiness to learn. Purpose: The purpose of this study was to examine the effect of a before-school running/walking club on children's physical activity and on-task behavior. Methods: Participants were third and fourth grade children from two schools in the Southwestern United States who participated in a before-school running/walking club that met two times each week. The study employed a two-phase experimental design with an initial baseline phase and an alternating treatments phase. Physical activity was monitored using pedometers and on-task behavior was assessed through systematic observation. Data analysis included visual analysis, descriptive statistics, as well as multilevel modeling. Results: Children accumulated substantial amounts of physical activity within the before-school program (School A: 1731 steps, 10:02 MVPA minutes; School B: 1502 steps, 8:30 MVPA minutes) and, on average, did not compensate by decreasing their physical activity during the rest of the school day. Further, on-task behavior was significantly higher on days the children attended the before-school program than on days they did not (School A=15.78%, pseudo-R2=.34 [strong effect]; School B=14.26%, pseudo-R2=.22 [moderate effect]). Discussion: Results provide evidence for the positive impact of before-school programs on children's physical activity and on-task behavior. Such programs do not take time away from academics and may be an attractive option for schools.

Description
The Accelerated Reader Program has been a widely used reading program in elementary schools in the United States. However, even with its popularity, there have been controversies on if and how it should be used in the classroom. Arguments in support say the program gets children to read and that it is a helpful tool for teachers to keep track of each students reading abilities. Arguments against suggest that book choice is decreased, book levels are askew, the quizzes do not promote higher level thinking, and the use of incentives may send the wrong signals to students. Schools have started to abandon the program in the recent years, but maybe it will come back bigger and stronger. In the meantime, schools need to make sure that enriching books fill the schools and classrooms to promote reading for their students.

Description
Dual Language Immersion programs have been growing exponentially as a result of an urgent need for globally competent, bilingual or multilingual citizens. The US is currently facing a language deficit, which negatively affects national security, international relations and even the economy. If America wants to stay in contention as one of the strongest world powers, the US needs to foster more interest in learning foreign languages earlier and invest in the development of foreign language education. The purpose of this paper is to provide an overview of the history and implementation of different Dual Language Immersion program models. The geographical scope of the paper will cover historical background in Canada and the current implementation of Dual Language Immersion models in three Southwestern states: California, Utah and Arizona. The paper also outlines challenges related to the implementation of these dual language immersion programs.

Description
Unmanned aerial vehicles have received increased attention in the last decade due to their versatility, as well as the availability of inexpensive sensors (e.g. GPS, IMU) for their navigation and control. Multirotor vehicles, specifically quadrotors, have formed a fast growing field in robotics, with the range of applications spanning from surveil- lance and reconnaissance to agriculture and large area mapping. Although in most applications single quadrotors are used, there is an increasing interest in architectures controlling multiple quadrotors executing a collaborative task. This thesis introduces a new concept of control involving more than one quadrotors, according to which two quadrotors can be physically coupled in mid-flight. This concept equips the quadro- tors with new capabilities, e.g. increased payload or pursuit and capturing of other quadrotors. A comprehensive simulation of the approach is built to simulate coupled quadrotors. The dynamics and modeling of the coupled system is presented together with a discussion regarding the coupling mechanism, impact modeling and additional considerations that have been investigated. Simulation results are presented for cases of static coupling as well as enemy quadrotor pursuit and capture, together with an analysis of control methodology and gain tuning. Practical implementations are introduced as results show the feasibility of this design.

Description
BACKGROUND: The City of Phoenix initiated the HeatReady program in 2018 to prepare for extreme heat, as there was no official tool, framework, or mechanism at the city level to manage extreme heat. The current landscape of heat safety culture in schools, which are critical community hubs, has received less illumination. HeatReady Schools—a critical component of a HeatReady City—are those that are increasingly able to identify, prepare for, mitigate, track, and respond to the negative impacts of schoolgrounds heat. However, minimal attention has been given to formalize heat preparedness in schools to mitigate high temperatures and health concerns in schoolchildren, a heat-vulnerable population. This study set out to understand heat perceptions, (re)actions, and recommendations of key stakeholders and to identify critical themes around heat readiness. METHODS: An exploratory sequential mixed-methods case study approach was used. These methods focused on acquiring new insight on heat perceptions at elementary schools through semi-structured interviews using thematic analysis and the Delphi panel. Participants included public health professionals and school community members at two elementary schools—one public charter, one public—in South Phoenix, Arizona, a region that has been burdened historically with inequitable distribution of heat resources due to environmental racism and injustices. RESULTS: Findings demonstrated that 1) current heat safety resources are available but not fully utilized within the school sites, 2) expert opinions support that extreme heat readiness plans must account for site-specific needs, particularly education as a first step, and 3) students are negatively impacted by the effects of extreme heat, whether direct or indirect, both inside and outside the classroom. CONCLUSIONS: From key informant interviews and a Delphi panel, a list of 30 final recommendations were developed as important actions to be taken to become “HeatReady.” Future work will apply these recommendations in a HeatReady School Growth Tool that schools can tailor be to their individual needs to improve heat safety and protection measures at schools.

Description
There has been a vast increase in applications of Unmanned Aerial Vehicles (UAVs) in civilian domains. To operate in the civilian airspace, a UAV must be able to sense and avoid both static and moving obstacles for flight safety. While indoor and low-altitude environments are mainly occupied by static obstacles, risks in space of higher altitude primarily come from moving obstacles such as other aircraft or flying vehicles in the airspace. Therefore, the ability to avoid moving obstacles becomes a necessity
for Unmanned Aerial Vehicles.
Towards enabling a UAV to autonomously sense and avoid moving obstacles, this thesis makes the following contributions. Initially, an image-based reactive motion planner is developed for a quadrotor to avoid a fast approaching obstacle. Furthermore, A Dubin’s curve based geometry method is developed as a global path planner for a fixed-wing UAV to avoid collisions with aircraft. The image-based method is unable to produce an optimal path and the geometry method uses a simplified UAV model. To compensate
these two disadvantages, a series of algorithms built upon the Closed-Loop Rapid Exploratory Random Tree are developed as global path planners to generate collision avoidance paths in real time. The algorithms are validated in Software-In-the-Loop (SITL) and Hardware-In-the-Loop (HIL) simulations using a fixed-wing UAV model and in real flight experiments using quadrotors. It is observed that the algorithm enables a UAV to avoid moving obstacles approaching to it with different directions and speeds.

Description
For some children, peer victimization stops rather quickly, whereas for others it marks the beginning of a long trajectory of peer abuse (Kochenderfer-Ladd & Wardrop, 2001). Unfortunately, we know little about these trajectories and what factors may influence membership in increasing or decreasing victimization over time. To address this question, I identified children's developmental patterns of victimization in early elementary school and examined which child-level factors influenced children's membership in victimization trajectories using latent growth mixture modeling. Results showed that boys and girls demonstrated differential victimization patterns over time that also varied by victimization type. For example, boys experienced more physical victimization than girls and increased victimization over time was predicted by boys who display high levels of negative emotion (e.g., anger) towards peers and low levels of effortful control (e.g., gets frustrated easily). Conversely, girls exhibited multiple trajectories of increasing relational victimization (i.e., talking about others behind their back) over time, whereas most boys experienced low levels or only slightly increasing relational victimization over time. For girls, withdrawn behavior lack of positive emotion, and displaying of negative emotions was predictive of experiencing high levels of victimization over time.

Description
This study explored the science learning experiences of elementary English Language Learners (ELLs) in a fourth-grade mainstream science classroom in an urban setting. Informed by ethnographic research and case study design, this study interrogated the celebrated and marginalized practices within common classroom procedures and what science-related identities the focal ELLs developed within classroom interactions through the lens of identity as position. Additionally, this study examined how the focal ELLs perceived themselves as science learners and how they affiliated with what scientists do and school science. Data collection lasted for two months and included video recordings of science instruction and classroom interactions, interviews with the focal ELLs, and students’ artifacts. Findings revealed that “doing science” in this fourth-grade science classroom was narrowly defined, as the celebrated practices involved mainly following the classroom behavioral codes and telling the right answer to the teacher’s questions. Findings also showed that the three focal ELLs complied with the celebrated practices to various degrees and were positioned marginally or negatively by the teacher and peers. The marginal and negative positioning affected the focal ELLs’ opportunities to engage meaningfully in classroom learning activities. Finally, findings regarding the focal ELLs’ perceptions of themselves as science learners showed the various ways in which they used their experiences inside and outside the classroom to construct their understanding of and relations with scientists and the science subject. This study provided implications for student science identity research and practice for supporting ELLs in the mainstream science classroom.

Description
Research indicates that social changes have resulted in children exercising much less than in the past. This is problematic since physical activity throughout the elementary school day is imperative, because exercise improves academic focus, boosts mood, and leads to a healthier lifestyle. Exercising is pivotal for all students but even more so for students in the Special Education classroom who may rely on physical activity as a way of regulating their emotions. Depending on the school, students may only exercise at recess and during their Physical Education electives. Lack of physical activity can be detrimental to the academic and physical success of a student.
This thesis explores the impact of physical activity--what I have chosen to call “moments of movement” -- inside the classroom throughout the elementary school day. Journal-based observations were made by a student teacher placed in a special education 4th-6th grade writing and reading resource classroom from August-December of 2018 and a fourth grade general education classroom from January-May of 2019. All observations were made at Adams Elementary School, a Title 1 school, in the Mesa, Arizona school district. At this K-6 grade school, many students live with the challenges of poverty, neglect, unstable family dynamics, and trauma. Because the teachers work tirelessly to cultivate a sense of home for the students, there is a strong emphasis on non-traditional teaching methods, including the AVID program and the Kagan, and Tribes strategies.
Ms. Norris (the special education teacher) and Ms. Foss (the fourth grade teacher) both have strong backgrounds in fitness and naturally incorporate physical activity in their classrooms, which is not something typically found at elementary schools. In this paper, physical activity strategies in classrooms of Ms. Norris and Ms. Foss are analyzed, as well as the benefits of implementing these strategies. The impact of these “moments of movement” on the whole class and individual students is discussed, and suggestions are made to help educators incorporate “moments of movement” into their own classrooms. Educators can use the strategies present at Adams Elementary School as a model for incorporating exercise in their own classrooms.

Children are our future businesspeople, policy makers, and educators. As such, during their careers and throughout their life, they will be the leaders making tough decisions on how to respond to extreme heat phenomenon, rising sea levels, changing weather patterns, and the increased presence of greenhouse gases, which could thrust our Earth into irreversible change if emissions are

Each course incorporates important sustainability themes into the required Next Generation Science Standards, to encourage teachers to adopt these unit plans without taking away limited class time to teach about sustainability. Rather than ending in doom and gloom, students finish each unit becoming the heroes of the story by creating their own solutions to combat climate change that they can implement into their own lives, communities, homes, and classroom.
Sustainability and climate related issues are already sweeping our Earth and the problem is likely going to accelerate as today's current elementary school students start their professional careers.
