Description
In recent years we have witnessed a shift towards multi-processor system-on-chips (MPSoCs) to address the demands of embedded devices (such as cell phones, GPS devices, luxury car features, etc.). Highly optimized MPSoCs are well-suited to tackle the complex application demands desired by the end user customer. These MPSoCs incorporate a constellation of heterogeneous processing elements (PEs) (general purpose PEs and application-specific integrated circuits (ASICS)). A typical MPSoC will be composed of a application processor, such as an ARM Coretex-A9 with cache coherent memory hierarchy, and several application sub-systems. Each of these sub-systems are composed of highly optimized instruction processors, graphics/DSP processors, and custom hardware accelerators. Typically, these sub-systems utilize scratchpad memories (SPM) rather than support cache coherency. The overall architecture is an integration of the various sub-systems through a high bandwidth system-level interconnect (such as a Network-on-Chip (NoC)). The shift to MPSoCs has been fueled by three major factors: demand for high performance, the use of component libraries, and short design turn around time. As customers continue to desire more and more complex applications on their embedded devices the performance demand for these devices continues to increase. Designers have turned to using MPSoCs to address this demand. By using pre-made IP libraries designers can quickly piece together a MPSoC that will meet the application demands of the end user with minimal time spent designing new hardware. Additionally, the use of MPSoCs allows designers to generate new devices very quickly and thus reducing the time to market. In this work, a complete MPSoC synthesis design flow is presented. We first present a technique \cite{leary1_intro} to address the synthesis of the interconnect architecture (particularly Network-on-Chip (NoC)). We then address the synthesis of the memory architecture of a MPSoC sub-system \cite{leary2_intro}. Lastly, we present a co-synthesis technique to generate the functional and memory architectures simultaneously. The validity and quality of each synthesis technique is demonstrated through extensive experimentation.

Description
The quality and quantity of talented members of the US STEM workforce has
been a subject of great interest to policy and decision makers for the past 40 years.
Recent research indicates that while there exist specific shortages in specific disciplines
and areas of expertise in the private sector and the federal government, there is no
noticeable shortage in any STEM academic discipline, but rather a surplus of PhDs
vying for increasingly scarce tenure track positions. Despite the seeming availability
of industry and private sector jobs, recent PhDs still struggle to find employment in
those areas. I argue that the decades old narrative suggesting a shortage of STEM
PhDs in the US poses a threat to the value of the natural science PhD, and that
this narrative contributes significantly to why so many PhDs struggle to find career
employment in their fields. This study aims to address the following question: what is
the value of a STEM PhD outside academia? I begin with a critical review of existing
literature, and then analyze programmatic documents for STEM PhD programs at
ASU, interviews with industry employers, and an examination the public face of value
for these degrees. I then uncover the nature of the value alignment, value disconnect,
and value erosion in the ecosystem which produces and then employs STEM PhDs,
concluding with specific areas which merit special consideration in an effort to increase
the value of these degrees for all stakeholders involved.

Description
We, a team of students and faculty in the life sciences at Arizona State University (ASU), currently teach an Introduction to Biology course in a Level 5, or maximum-security unit with the support of the Arizona Department of Corrections and the Prison Education Program at ASU. This course aims to enhance current programs at the unit by offering inmates an opportunity to practice literacy and math skills, while also providing exposure to a new academic field (science, and specifically biology). Numerous studies, including a 2005 study from the Arizona Department of Corrections (ADC), have found that vocational programs, including prison education programs, reduce recidivism rates (ADC 2005, Esperian 2010, Jancic 1988, Steurer et al. 2001, Ubic 2002) and may provide additional benefits such as engagement with a world outside the justice system (Duguid 1992), the opportunity for inmates to revise personal patterns of rejecting education that they may regret, and the ability of inmate parents to deliberately set a good example for their children (Hall and Killacky 2008). Teaching in a maximum security prison unit poses special challenges, which include a prohibition on most outside materials (except paper), severe restrictions on student-teacher and student-student interactions, and the inability to perform any lab exercises except limited computer simulations. Lack of literature discussing theoretical and practical aspects of teaching science in such environment has prompted us to conduct an ongoing study to generate notes and recommendations from this class through the use of surveys, academic evaluation of students' work and ongoing feedback from both teachers and students to inform teaching practices in future science classes in high-security prison units.

Description
Various reports produced by the National Research Council suggest that K-12 curricula expand Science, Technology, Engineering, and Mathematics to better help students develop their ability to reason and employ scientific habits rather than simply building scientific knowledge. Every spring, the Arizona Department of Education (ADE) in conjunction with Arizona State University holds a professional development workshop titled "Engineering Practices in the Secondary Science Classroom: Engineering Training for Grade 6-12 Math and Science School Teams". This workshop provides math and science teachers with the opportunity to either sustain existing engineering proficiency or be exposed to engineering design practices for the first time. To build teachers' proficiency with employing engineering design practices, they follow a two-day curriculum designed for application in both science and math classrooms as a conjoined effort. As of spring 2015, very little feedback has been received concerning the effectiveness of the ASU-ADE workshops. New feedback methods have been developed for future deployment as past and more informal immediate feedback from teachers and students was used to create preliminary changes in the workshop curriculum. In addition, basic laboratory testing has been performed to further link together engineering problem solving with experiments and computer modelling. In improving feedback and expanding available material, the curriculum was analyzed and improved to more effectively train teachers in engineering practices and implement these practices in their classrooms.

Description
This thesis aims to evaluate how in classroom demonstrations compare to regular education techniques, and how student learning styles affect interest in science and engineering as future fields of study. Science education varies between classrooms, but usually is geared towards lecture and preparation for standardized exams without concern for student interest or enjoyment.5 To discover the effectiveness of demonstrations in these concerns, an in classroom demonstration with a water filtration experiment was accompanied by several modules and followed by a short survey. Hypotheses tested included that students would enjoy the demonstration more than a typical class session, and that of these students, those with more visual or tactile learning styles would identify with science or engineering as a possible major in college. The survey results affirmed the first hypothesis, but disproved the second hypothesis; thus illustrating that demonstrations are enjoyable, and beneficial for sparking or maintaining student interest in science across all types of students.

Clean and accessible drinking water is a crucial and limited resource. As the world's population grows and demand increases, water resources will become more limited. This project aims to educate students on water resources, drinking water, and how biomimicry can allow society to improve its water usage. The project consists of a ten day unit plan which addresses several water topics such as: the various uses of water, water distribution, where drinking water comes from, the water treatment process, and more. After establishing background knowledge on water and surrounding issues, the students will be challenged to design a water bottle using biomimicry. Biomimicry is looking at nature to draw and inspire solutions to human problems. This unit has been optimized for use by elementary teachers. The ten day unit consists of a lesson summary, objectives, standards, and recommended activities for each day. Of the ten days, three lesson plans were fully developed using the 5E format. The research supporting this project is compiled in the following report.

Description
Museum evaluation is an important process that aims to study an exhibit's effectiveness in engaging visitors and in teaching concepts. Imperatives and methods to strengthen museum evaluation have been suggested and implemented in the past, but ultimately faced several challenges including the collection of visitor feedback in an efficient, non-intrusive way. The Ask Dr. Discovery project seeks to address the challenge of conducting efficient, affordable, and large-scale science museum evaluation via an interactive app aimed at collecting direct visitor feedback through use of the app and through questionnaires that also collect demographics. This thesis investigates how the demographics of metro Phoenix science museum visitors as a whole compare to the Hispanic/Latino population of visitors, and makes use of visitor feedback from Ask Dr. Discovery to provide useful data for science museum evaluation. An analysis of responses revealed that the majority of the participants in the study (n=785) were White (Non-Hispanic) (65.59%), were 36-45 years old (36.18%) and hold a graduate degree (27.64%). Most Hispanic/Latino participants in the study were 26-35 years old (36.36%) and completed some college (28.67%). Most participants from both participant groups have never visited the museum before (32.99% of all participants; 33.57% of all Hispanics/Latinos). Further analysis suggest that museum visits may be independent of age and visitor group size. Visitor interest in science museum exhibits may be independent of their use of free time science-related activities. Data suggests that there was no real difference in exhibit interest across two different versions of the app ("modes"). Analysis of negative visitor feedback showed different question types, questions asked, and time spent on the app. Data log questions revealed the difference in time spent on the app and complexity of questions asked between adults and children, as well as the location of participants in the museum. There was no major correlation between mode type and number of questions asked, and length of use and number of questions asked.

Description
The project was designed to increase awareness of sustainability and environmental science in public high school students who would otherwise not be exposed to complex environmental problems. This was done by testing the effectiveness of a simple yet comprehensive curriculum that could satisfy and expand the scope of the Arizona Education Science Standard, Essential HS.E1U3.14, while simultaneously being accessible to (and teachable by) any school instructor. Another goal of the project is to stimulate the minds of students who would otherwise not be introduced to the topics of sustainability and environmental science. Utilizing proven visualization and engagement techniques, the curriculum focuses on five key subjects: waste, water, energy, ecosystems, and environmental challenges. Each of these subjects had an educational presentation, interactive activities, question and answer sessions, and bonus activities. To test the overall effectiveness of the curriculum, students were given a pretest to gauge initial comprehension, and then after the five subjects (or modules) were taught, the same test was distributed again to the students. The aforementioned was done with two groups of students. Posttest results support the project effectiveness. The data indicate that the lessons had a positive impact on the test results, with one class averaging 33.6% better on the posttest than the pretest, indicating that the concepts taught did resonate with the students in a measurable way.

Pedagogical researchers have explored pop culture media in educational settings in the past. However, pop culture media is always evolving. Teachers should be aware that students have already formed their own cultural activities and work with them, rather than neglect them. Anime has remained largely unexplored in this context despite its popularity. Its animation style and storyline may provide exciting moments that are memorable to young adults. This study examines the potential of anime, a style of Japanese animation, in educating through a visual medium. Recent anime have successfully incorporated science into their storytelling.
The 2019 anime, Dr. Stone, follows a high schooler and his friends as they attempt to use science to restore human society after 3,700 years of global petrification. Through qualitative analysis and coding of select episodes of Dr. Stone, this study examines the ways in which scientific concepts in engineering, chemistry and geology are taught. It also examines the significance of science and representation of scientists within its storyline. Dr. Stone presents an image of science which is interesting, relevant and understandable to adolescent students through its compelling visuals and engaging story. Through its characters, it also presents a relatable and less stereotypical image of scientists. Innovative pop culture media like anime is one way of generating interest in science among adolescents and challenging preconceived notions of science. Educators may find it useful in a classroom setting.

Description
Public education and involvement with evolutionary theory has long been limited by both the complexity of the subject and societal pushback. Furthermore, effective and engaging evolution education has become an elusive feat that often fails to reflect the types of questions that evolution research attempts to address. Here, we explore the best methods to present scientific research using interactive educational models to facilitate the learning experience of the audience most effectively. By creating artistic and game-play oriented models, it becomes possible to simplify the multifaceted aspects of evolution research such that it enables a larger, more inclusive, audience to better comprehend these complexities. In allowing the public to engage with highly interactive education materials, the full spectrum of the scientific process, from hypothesis construction to experimental testing, can be experienced and understood. Providing information about current cancer evolution research in a way that is easy to access and understand and accompanying it with an interactive model that reflects this information and reinforces learning shows that research platforms can be translated into interactive teaching tools that make understanding evolutionary theory more accessible.
