Description
Among researchers, educators, and other stakeholders in literacy education, there has been a growing emphasis on developing literacy pedagogies that are more responsive to the ways young people experience literacy in their everyday lives, which often make use of digital media and other technologies for exchanging meaning. This dissertation project sought to explore the nature of these digital-age literacies in the context of children learning through and about new technologies. Conducting a year-long, multimethod observational study of an out-of-school library-based program designed to engage students in self-directed learning around the domain of computer programming, this project was framed around an analysis of digital-age literacies in design, discourse, and practice. To address each of these areas, the project developed a methodology grounded in interpretive, naturalistic, and participant-observation methodologies in collaboration with a local library Code Club in a metropolitan area of the Southwestern U.S between September 2016 and December 2017. Participants in the project included a total of 47 students aged 8-14, 3 librarians, and 3 parents. Data sources for the project included (1) artifactual data, such as the designed interfaces of the online platforms students regularly engaged with, (2) observational data such as protocol-based field notes taken during and after each Code Club meeting, and (3) interview data, collected during qualitative interviews with students, parents, and library facilitators outside the program. These data sources were analyzed through a multi-method interpretive framework, including the multimodal analysis of digital artifacts, qualitative coding, and discourse analysis. The findings of the project illustrate the multidimensional nature of digital-age literacy experiences as they are rendered “on the screen” at the content level, “behind the screen” at the procedural level, and “beyond the screen” at the contextual level. The project contributes to the literature on literacy education by taking an multi-method, interdisciplinary approach to expand analytical perspectives on digital media and literacy in a digital age, while also providing an empirical account of this approach in a community-embedded context of implementation.

Description
The advancement of technology has substantively changed the practices of numerous professions, including teaching. When an instructor first adopts a new technology, established classroom practices are perturbed. These perturbations can have positive and negative, large or small, and long- or short-term effects on instructors’ abilities to teach mathematical concepts with the new technology. Therefore, in order to better understand teaching with technology, we need to take a closer look at the adoption of new technology in a mathematics classroom. Using interviews and classroom observations, I explored perturbations in mathematical classroom practices as an instructor implemented virtual manipulatives as novel didactic objects in rational function instruction. In particular, the instructor used didactic objects that were designed to lay the foundation for developing a conceptual understanding of rational functions through the coordination of relative size of the value of the numerator in terms of the value of the denominator. The results are organized according to a taxonomy that captures leader actions, communication, expectations of technology, roles, timing, student engagement, and mathematical conceptions.

Description
The purpose of this thesis is to examine the current state of the brick-and-mortar bookselling industry, with particular focus on independent bookstores and their strengths and weaknesses, and synthesizing recommendations for these bookstores to reinvent themselves in a rapidly changing market. This examination is highly relevant given recent concerns that, with the rise of e-retailers like Amazon and the closure of bookstore chain Borders, brick-and-mortar bookstores may be superseded by new digital vendors. Independent bookstores are thought to be at a particular disadvantage to these retailers, given their limited size and resources, as well as the lack of capital or consumer base that a larger chain like Barnes and Noble can draw upon to invest in emerging technology. With these more limited financial opportunities, independent bookstores must find different ways to not only keep abreast of the technology that consumers are coming to expect from modern businesses, but attract customers.
To gain insight into the state of the industry and current position of independent bookstores, I will first examine the past fifty years of the brick-and-mortar bookstore, followed by a Porter’s Five Forces analysis of the industry threats and a SWOT analysis to compare the strengths and weaknesses of independent bookstores. Next, the patrons of independent bookstores will be discussed with a focus on the two largest consumer groups of Millennials and Baby Boomers, their characteristics, and the opportunities they provide to bookstores. After this there will be an exploration of the competitors to brick-and-mortar bookstores, focusing on Amazon and then touching on some of the other rivals to bookstores’ consumer base. The next section will be an in-depth analysis of a variety of bookstores across the United States, with attention to their successful practices, goals, concerns, and failures. First, there will be a comparison of industry success and failure through case studies of Borders and Powell’s bookstores. Next, there will be a comparison of five beloved independent bookstores across the country to share their varied competitive advantages that are the secret to their success. Finally, there are primary source interviews with the employees of three major Phoenix bookstores, which provide insight into the goals, current projects, attitudes, and inner strengths of these businesses. Finally, the thesis will conclude with a section offering solutions and suggestions for independent bookstores to pursue based on the primary and secondary research discussed above. These recommendations are focused on five key areas:
• Community
• Consumers
• Store Design
• Technology
• Diversification
Ultimately, the information provided by this research and these interviews indicates that while vital business changes are being pursued by independent and chain bookstores across the United States, the independent bookstore shows no signs of disappearing in favor of online vendors or e-readers.

Description
This is a case study of weathercasters in a large U.S. television market from five different English speaking stations conducted before, during, and after a severe weather season. The research applies the ethnographic process to inscribe and define the culture of local weathercasters in the news environment. The purpose of this study is to examine the extant cultural characteristics discerned by weathercasters and the changes in weather broadcast technology used by live “on-air” television personnel. Forty-nine elite, in depth interviews with 17 different weathercasters along with participant and non-participant observation yielded transcripts and field notes obtained during the six month data acquisition phase. Using qualitative methods and the CAQDAS program Dedoose, 953 coded excerpts from the transcripts were analyzed for various patterns, behaviors, and characteristics relevant to culture, technology, and perceptions of weathercasters. The excerpts revealed dominant cultural aspects defined as dichotomous differences, autonomous functions, and identity perceptions. Socio-technical models are explicated in relationship to control, knowledge, and strategic coping mechanisms. The newsroom and weathercaster co-cultural context is defined by the conformity versus autonomy relationship and the external and internal structure of the weathercaster’s working environment is delineated. Co-cultural models explain the way influence operates in severe weather situations within the newsroom culture. The results have utility for scholars studying technology, culture, newsroom routines, rituals, and professionals who work in the television news industry. The findings are highly relevant for television weathercasters, newsroom producers, and broadcast managers.

Description
This dissertation is about videogames. It is also about teaching, and the ways videogame design represents good teaching. However, this dissertation is not about videogames alone. It makes broad claims about teaching in- and out-of-schools in the 21st Century. Over the last few decades many scholars have been impressed by the rich forms of learning going on out-of-school. In particular, the emergence of digital and social media has fueled interest in informal learning while often ignoring or effacing the critical role of teaching. Indeed, the term “informal learning” is common while the term “informal teaching” barely exists. At the same time, the learning sciences have made progress on understanding how learning works based on empirical evidence of how the mind operates. While this research is not well implemented in many of our schools, it is well represented in much out-of-school learning (such as in videogames). This dissertation argues that there is a body of evidence germane to good teaching, that many learning principles celebrated today in out-of-school learning are actually teaching principles, and that good videogames can give us insights into how teaching can work as a form of design with or without games. The dissertation then develops a model of distributed teaching and learning systems which involve designed- and emergent organization of various teaching and learning “sites”. Finally, the dissertation looks at the rhetorical function of teaching in building a “deliberate learner,” one whose goal is not simply to know and do things, but to become a certain type of person committed to new ways with words, forms of interaction, and values. Rhetoric, teaching, learning, and design of all sorts have been set free from institutions and turned loose into a market place of ideas and sites. In the face of this market place we need to engage in discussions about who we want to be, who we want others to be, and what world we want all of us to live in. These discussions will center not just on “truth”, but on values as well—which is exactly where, in a high-risk imperiled world, they should be centered.

Description
This study aimed to explore the relationship between international backpackers and local communities in the developing world. By investigating the role of technology design in a backpacking trip, this research analyzed the potential to improve Sustainable Tourism for both international backpackers and local communities. The idea of achieving sustainability in this research is to assess both economic and cultural impact through the assistance of technology. This study originates from a grounded theory approach triangulated from literature reviews and the researcher’s observations. The research tested the suitability of this theory by using qualitative research methods, then analyzed the appropriateness of its applicability. The findings suggested some useful standards for proposing design solutions to enhance sustainable tourism within the backpacker segment

Description
This study is a cultural history of danger, disaster, and steam-powered transportation in nineteenth-century America. The application of steam power to transportation, a globally transformative innovation, had particular influence in the early United States. A vast American continent with difficult terrain and poor infrastructure posed significant challenges, both to individual mobility and to a nation eager to build an integrated economy, a unified culture, and a functional republican government. Steamboats and locomotives offered an apparent solution, their speed and power seemingly shrinking distances between places and expanding mobility and access across space, a process contemporaries and scholars have described as a sort of space-time compression. However, these machines that overcame space also blew up, caught fire, wrecked, collided, derailed, and broke down, killing tens, and often hundreds, of Americans at a time. This dissertation analyzes the ways Americans encountered, interpreted, and adapted to these new dangers, all the while making the technology that created them an ever more essential aspect of their lives. I argue that Americans’ responses to disasters, filtered through the transportation and communication networks created by steam power, constituted a deep, shared reflection about the nature of expanded mobility in a fast-evolving modern America. Though few suffered disaster directly, Americans collectively framed the danger of steam as both a profound national problem and an evocative symbol of modernity. Through public conversations mediated by print, Americans identified susceptibility to danger as inherent to high-speed travel, and, alongside practical safety measures, developed distinctly modern cultural adaptations to understand and manage that danger. By century's end, Americans had cultivated a modern mentality on mobility, technology, and danger: though most Americans never experienced disaster they were intimately aware of it, and though familiar with catastrophe they understood it as unlikely and accepted it as a feature of their modern technological lives.

Description
Background: Smartphone diet tracking applications (apps) are increasing in popularity but may not adequately address the important concerns of proper intake and of diet quality. Two novel weight loss apps were designed based on the popular dietary frameworks: MyPlate and FoodLists. MyPlate, the dietary guidelines put forth by the U.S. government, encourages a balanced diet from five primary food groups, but does not specify intake limits. The Food Lists set upper intake limits on all food groups except vegetables, and these guidelines extend to include fats, sweets, and alcohol.
Objective: The purpose of this randomized controlled trial was to determine whether adherence to a weight loss app providing intake limits and more food group detail (the Food Lists app) facilitated more weight loss and better diet quality than adherence to a weight loss app based on the MyPlate platform. An additional objective was to examine whether higher app adherence would lead to greater weight loss.
Design: Thirty seven adults from a campus population were recruited, randomized, and instructed to follow either the Food Lists app (N=20) or the MyPlate app (N=17) for eight weeks. Subjects received one 15 minute session of diet and app training at baseline, and their use of the app was tracked daily. Body mass was measured at baseline and post-test.
Participants/setting: Healthy adults from a university campus population in downtown Phoenix, Arizona with BMI 24 to 40, medically stable, and who owned a smartphone.
Main outcome measures: Outcome measures included weight change, days of adherence, and diet quality change. Secondary measures included BMI, fat %, and waist circumference.
Statistical analysis: Descriptive statistics (means and standard errors); Repeated measures ANOVAs analyzing weight, diet quality, and BMI; Pearson and Spearman correlations analyzing adherence and weight loss.
Results: Repeated measures ANOVAs and correlations revealed no significant mean differences in primary outcome variables of weight loss, adherence, or diet quality (P=0.140; P=0.790; P=0.278). However, there was a significant mean reduction of BMI favoring the group using the Food Lists app (P=0.041).
Conclusion: The findings strengthen the idea that intake limits and food group detail may be associated with weight loss. Further investigation is warranted to determine whether longer use of the Food Lists app can produce more significant dieting successes and encourage healthier behavioral outcomes.

A lot of strides have been made in enabling technologies to aid individuals with visual impairment live an independent life. The advent of smart devices and participatory web has especially facilitated the possibility of new interactions to aide everyday tasks. Current systems however tend to be complex and require multiple cumbersome devices which invariably come with steep learning curves. Building new cyber-human systems with simple integrated interfaces while keeping in mind the specific requirements of the target users would help alleviate their mundane yet significant daily needs. Navigation is one such significant need that forms an integral part of everyday life and is one of the areas where individuals with visual impairment face the most discomfort. There is little technology out there to help travelers with navigating new routes. A number of research prototypes have been proposed but none of them are available to the general population. This may be due to the need for special equipment that needs expertise before deployment, or trained professionals needing to calibrate devices or because of the fact that the systems are just not scalable. Another area that needs assistance is the field of education. Lot of the classroom material and textbook material is not readily available in alternate formats for use. Another such area that requires attention is information delivery in the age of web 2.0. Popular websites like Facebook, Amazon, etc are designed with sighted people as target audience. While the mobile editions with their pared down versions make it easier to navigate with screen readers, the truth remains that there is still a long way to go in making such websites truly accessible.

Description
Purpose: The purpose of this study was to evaluate the efficacy of the EMBRACE Spanish support intervention for at-risk dual language learners and to determine which verbal and nonverbal characteristics of students were related to benefit from the intervention. The first study examined oral language and reading characteristics and the second study examined motor characteristics in predicting the children's outcomes on a reading comprehension intervention.
Method: Fifty-six participants in 2nd-5th grade were randomly assigned to one of two groups: 1) Spanish-support intervention, or 2) Spanish-support control. Outcome measures included performance on comprehension questions related to intervention texts, questions on the final narrative and expository text without strategy instruction, and difference scores on alternate forms of the Gates-MacGinitie (GMRT-4, MacGinitie, MacGinitie, Maria, & Dreyer, 2002) reading comprehension subtest administered pre- post-intervention. Multi-level hierarchical linear models were used to account for nesting of question within child within classroom. Regression models were used to examine the power of motor predictors in predicting Spanish and English language performance.
Results: Results from study 1 indicated that the intervention was most effective for narrative (vs. expository) texts and easy (vs. more difficult) texts. Dual language learners (DLLs) with lower initial English reading comprehension abilities benefitted more from the intervention than those with stronger reading skills. Results from Study 2 indicated that oral fine motor abilities predicted Spanish (but not English) oral language abilities in the expected direction (i.e. faster performance associated with higher language scores). The speed of /pata/ productions predicted reading comprehension during the intervention, but not in the expected direction (i.e. slower speeds associated with higher accuracy). Manual fine motor performance on tapping tasks was not related to language or reading.
Conclusions: The EMBRACE intervention has promise for use with at-risk DLLs. Future research should take care to match text difficulty with child skills so as to maximize benefit from the intervention. Oral fine motor abilities were related to language abilities in DLLs, but only for the native language. Slower oral fine motor performance predicted higher accuracy on intervention questions, suggesting that EMBRACE may be particularly effective for children with weak fine motor skills.
