Description
Blind and visually impaired individuals have historically demonstrated a low participation in the fields of science, engineering, mathematics, and technology (STEM). This low participation is reflected in both their education and career choices. Despite the establishment of the Americans with Disabilities Act (ADA) and the Individuals with Disabilities Education Act (IDEA), blind and visually impaired (BVI) students continue to academically fall below the level of their sighted peers in the areas of science and math. Although this deficit is created by many factors, this study focuses on the lack of adequate accessible image based materials. Traditional methods for creating accessible image materials for the vision impaired have included detailed verbal descriptions accompanying an image or conversion into a simplified tactile graphic. It is very common that no substitute materials will be provided to students within STEM courses because they are image rich disciplines and often include a large number images, diagrams and charts. Additionally, images that are translated into text or simplified into basic line drawings are frequently inadequate because they rely on the interpretations of resource personnel who do not have expertise in STEM. Within this study, a method to create a new type of tactile 3D image was developed using High Density Polyethylene (HDPE) and Computer Numeric Control (CNC) milling. These tactile image boards preserve high levels of detail when compared to the original print image. To determine the discernibility and effectiveness of tactile images, these customizable boards were tested in various
university classrooms as well as in participation studies which included BVI and sighted students. Results from these studies indicate that tactile images are discernable and were found to improve performance in lab exercises as much as 60% for those with visual impairment. Incorporating tactile HDPE 3D images into a classroom setting was shown to increase the interest, participation and performance of BVI students suggesting that this type of 3D tactile image should be incorporated into STEM classes to increase the participation of these students and improve the level of training they receive in science and math.

Description
First-generation college students, for whom neither parent has a bachelor's degree, are at an increased risk for dropping out of college compared with their continuing-generation counterparts. This research aims to examine whether varying perceptions of the future may contribute to these differences; specifically, whether presentations of future opportunities with and without a college degree impact academic motivation and performance, and whether this relationship holds for people from different college generation status backgrounds. Additionally, the study explores whether the effect is consistent with regulatory focus profiles--whether someone is motivated to avoid negative outcomes (e.g., prevention orientation) or attain positive outcomes (e.g., promotion orientation). Prevention oriented first-generation students were expected to have increased motivation and performance when asked to contrast the future with and without a college degree, whereas promotion oriented continuing-generation students were expected to have increased motivation and performance by merely thinking about the future with a college degree. Participants consisted of 330 undergraduates from an introductory psychology course. Participants were randomly assigned to presentations of future opportunities with a degree, with and without a degree, or a no-prime control condition. Motivation and performance were assessed using academic motivation and delay of gratification scales and a short anagram task. The proposed hypotheses were not supported; however, important findings emerged from exploratory analysis. First- and continuing-generation college students perceived future opportunities with a college degree similarly, meaning that both first- and continuing-generation students believed that a degree would endow opportunities. Additionally, belief in future opportunities significantly predicted academic motivation, delay of gratification, and anagram performance; thus, belief in future opportunities is a determinant of academic motivation and performance. Finally, first-generation students' performance varied by belief that a college degree would create future opportunities. Therefore, future interventions to increase performance and retention among first-generation students should emphasize the value of a college degree for future success. This research has implications for the understanding of college generation status, academic motivation, and performance.

Description
Writing is an intricate cognitive and social process that involves the production of texts for the purpose of conveying meaning to others. The importance of lower level cognitive skills and language knowledge during this text production process has been well documented in the literature. However, the role of higher level skills (e.g., metacognition, strategy use, etc.) has been less strongly emphasized. This thesis proposal examines higher level cognitive skills in the context of persuasive essay writing. Specifically, two published manuscripts are presented, which both examine the role of higher level skills in the context of writing. The first manuscript investigates the role of metacognition in the writing process by examining the accuracy and characteristics of students' self-assessments of their essays. The second manuscript takes an individual differences approach and examines whether the higher level cognitive skills commonly associated with reading comprehension are also related to performance on writing tasks. Taken together, these manuscripts point towards a strong role of higher level skills in the writing process and provide a strong foundation on which to develop future research and educational interventions.

Description
Computational thinking, the creative thought process behind algorithmic design and programming, is a crucial introductory skill for both computer scientists and the population in general. In this thesis I perform an investigation into introductory computer science education in the United States and find that computational thinking is not effectively taught at either the high school or the college level. To remedy this, I present a new educational system intended to teach computational thinking called Genost. Genost consists of a software tool and a curriculum based on teaching computational thinking through fundamental programming structures and algorithm design. Genost's software design is informed by a review of eight major computer science educational software systems. Genost's curriculum is informed by a review of major literature on computational thinking. In two educational tests of Genost utilizing both college and high school students, Genost was shown to significantly increase computational thinking ability with a large effect size.

Description
The need for a critical education in a democracy, its difficulties, and how to reform this field requires urgent attention. This project begins with the premise that education is necessary for a vibrant democracy. While examining differing voices that advocate for educational reform, mainly that of Critical Pedagogy, it is shown how conflicting forms are advocating similar ideals. Henry Giroux and David Horowitz, both reformers that are on opposite sides of the political spectrum appear to have similar goals. Yet, the question becomes how to solve these differences between these parties? By examining the philosophical origins of these projects and explicating differences rooted in human nature and the good, the basic differences can begin to be shown. In showing these differences it requires going back to the work of Kant. Kant shows the necessity of beginning with philosophy and examining basic assumptions in order to begin to critique and build an education that would guarantee equality.

Description
Michael Apple's scholarship on curriculum, educational ideology, and official knowledge continues to be influential to the study of schooling. Drawing on the sociological insights of Pierre Bourdieu and the cultural studies approaches of Raymond Williams, Apple articulates a theory of schooling that pays particular attention to how official knowledge is incorporated into the processes of schooling, including textbooks. In an effort to contribute to Apple's scholarship on textbooks, this study analyzed high school American history textbooks from the 1960s through the 2000s with specific attention to the urban riots of the late-1960s, sixties counterculture, and the women's movement utilizing Julia Kristeva's psychoanalytic concept of abjection to augment Apple's theory of knowledge incorporation. This combination reveals not only how select knowledge is incorporated as official knowledge, but also how knowledge is treated as abject, as unfit for the curricular body of official knowledge and the selective tradition of American history. To bridge the theoretical frameworks of incorporation and abjection Raymond Williams' theory of structures of feeling and Slavoj iek's theory of ideological quilting are employed to show how feelings and emotional investments maintain ideologies. The theoretical framework developed and the interpretive analyses undertaken demonstrate how textbook depictions of these historical events structure students' present educational experiences with race, class, and gender.

Description
Conceptual change has been a large part of science education research for several decades due to the fact that it allows teachers to think about what students' preconceptions are and how to change these to the correct scientific conceptions. To have students change their preconceptions teachers need to allow students to confront what they think they know in the presence of the phenomena. Students then collect and analyze evidence pertaining to the phenomena. The goal in the end is for students to reorganize their concepts and change or correct their preconceptions, so that they hold more accurate scientific conceptions. The purpose of this study was to investigate how students' conceptions of the Earth's surface, specifically weathering and erosion, change using the conceptual change framework to guide the instructional decisions. The subjects of the study were a class of 25 seventh grade students. This class received a three-week unit on weathering and erosion that was structured using the conceptual change framework set by Posner, Strike, Hewson, and Gertzog (1982). This framework starts by looking at students' misconceptions, then uses scientific data that students collect to confront their misconceptions. The changes in students' conceptions were measured by a pre concept sketch and post concept sketch. The results of this study showed that the conceptual change framework can modify students' preconceptions of weathering and erosion to correct scientific conceptions. There was statistical significant difference between students' pre concept sketches and post concept sketches scores. After examining the concept sketches, differences were found in how students' concepts had changed from pre to post concept sketch. Further research needs to be done with conceptual change and the geosciences to see if conceptual change is an effective method to use to teach students about the geosciences.

Description
Being properly prepared is one of the keys to surviving an emergency or a disaster. In order to be prepared, people need appropriate education in preparedness, which includes elements of prevention, and planning. There is a definite need to better prepare our nation's citizens in order for them to safely respond in times of a disaster. It also seems likely that the earlier concepts and skills are learned, the easier those concepts and skills would be to remember and the more proficient one would become in implementing them. Therefore, it seems appropriate to teach emergency preparedness concepts and skills early on in the educational process. This means that significant efforts need to be directed toward learning, what impediments currently exist, what is helpful, and how preparedness concepts and skills can be taught to our children. A survey was distributed to third, fourth, and fifth grade teachers, asking them questions about emergency preparedness lessons in the classroom. Results indicated that the majority of teachers would be willing to teach emergency preparedness if the curriculum met current academic standards and they were given adequate resources to teach this subject. This study provides ideas, concepts and motivation for teachers to use in a cross-curricular approach to teaching emergency preparedness in the classroom. This is accomplished by presenting examples of newly developed curriculum/lesson plans that meet state academic standards, based on the current Community Emergency Response Team program and on children's fiction literature for the appropriate age group. A list of literature that could be used in this development is also provided in this study.

Description
Many school facility-planning theories have proposed an integrated role for schools within their surrounding neighborhood, advocating analogous approaches to creating "community schools" that involve social and community services at school sites that support both students and local residents. Despite the popularity of this concept in the education community, the idea of schools as community centers has not entered the mainstream of urban planning thought or practice. As the community schools movement continues to grow, planners should be engaged to support and leverage community school developments using their unique role as mediators of public and private interests. Furthermore, planners tend to have a broad perspective of communities that can facilitate synergistic partnerships and development patterns beyond the immediate school site. The aim of this research was to reframe the existing literature on community schools into a unified School-Oriented Development (SOD) neighborhood planning paradigm that 1) proposes a typology based on the relationships between schools and their surrounding communities, and 2) suggests urban form guidelines that will support these relationships in a child-friendly environment. These outcomes were achieved through the creation of a prototype SOD SmartCode Module that incorporates an SOD typology.

Description
Meter-resolution topography gathered by LiDAR (Light Detection and Ranging) has become an indispensable tool for better understanding of many surface processes including those sculpting landscapes that record information about earthquake hazards for example. For this reason, and because of the spectacular representation of the phenomena that these data provide, it is appropriate to integrate these data into Earth science educational materials. I seek to answer the following research question: "will using the LiDAR topography data instead of, or alongside, traditional visualizations and teaching methods enhance a student's ability to understand geologic concepts such as plate tectonics, the earthquake cycle, strike-slip faults, and geomorphology?" In order to answer this question, a ten-minute introductory video on LiDAR and its uses for the study of earthquakes entitled "LiDAR: Illuminating Earthquake Hazards" was produced. Additionally, LiDAR topography was integrated into the development of an undergraduate-level educational activity, the San Andreas fault (SAF) earthquake cycle activity, designed to teach introductory Earth science students about the earthquake cycle. Both the LiDAR video and the SAF activity were tested in undergraduate classrooms in order to determine their effectiveness. A pretest and posttest were administered to introductory geology lab students. The results of these tests show a notable increase in understanding LiDAR topography and its uses for studying earthquakes from pretest to posttest after watching the video on LiDAR, and a notable increase in understanding the earthquake cycle from pretest to posttest using the San Andreas Fault earthquake cycle exercise. These results suggest that the use of LiDAR topography within these educational tools is beneficial for students when learning about the earthquake cycle and earthquake hazards.
