<p> Examining teacher participation in collaborative microblogging activities may offer insight into creating alternative options for effective professional development. In this sequential explanatory mixed methods study, educators&rsquo; opinions of their use of a microblogging tool, Twitter, will be examined to determine what factors affect their participation in professional development activities using the microblogging tool, Twitter. The overall guiding question for this study will be, Why do educators participate in voluntary professional development opportunities, specifically in Twitter-supported professional learning networks? </p><p> This study will contribute to the existing body of research in the areas of professional development, professional learning networks, educator&rsquo;s motivation to learn, informal learning, online learning, and social media. Social media, specifically the microblogging tool Twitter, will be examined for its potential to act as an alternative mode of dissemination for educator professional development, as well as its potential for creating informal professional learning networks. Data sources for this study will include: surveys and interview questions. This information may be useful for future creation of more effective professional development opportunities. Findings from this study may be useful for researchers, educators, administrators, and developers of professional development opportunities.</p>

<p> Social media posts are used to examine what people experience in their everyday lives. A new method is developed for assessing the situational characteristics of social media posts based on the words used in these posts. To accomplish this, machine learning models are built that accurately approximate the judgments of human raters. This new method of situational assessment is applied on two of the most popular social media sites: Twitter and Facebook. Millions of Tweets and Facebook statuses are analyzed. Temporal patterns of situational experiences are found. Geographic and gender differences in experience are examined. Relationships between personality and situation experience were also assessed. Implications of these finding and future applications of this new method of situational assessment are discussed.</p>

<p> This dissertation explored how Korean students from a Midwestern university use social media when they come to the United States for the first time to start graduate school. In order to do so, I conducted a netnography which examines their virtual communities to observe language use (both English and Korean) within the their virtual circle of friends. I did so for a period of one semester, with archival data dating back to when they first found out they were coming to the US. This thesis is based on the argument that Korean graduate students go through a shift in linguistic, cultural, and social identity, and that social media can provide those in the field of literacy, culture, and language education a glimpse into the literacy and language practices of international students outside of the classroom. This dissertation also explains the theoretical framework behind virtual communities, analyzes current literature about virtual communities in language education, uses Kozinets&rsquo; (2009) netnography as a methodology to conduct the research, and analyzes semi-structured interviews, social media, and questionnaire data through Creswell&rsquo;s (2008) notion of thematic analysis. I conclude that the use of social media generally provides a means of identity expression for Korean graduate students, and that their linguistic, cultural, and social identities are not shaped by social media itself, but social media provides an outlet where we can see negotiation of identity from when they apply to the school and through their first semester of study; by using Korean as a language of social and cultural expression and English as a means of sharing information about their programs.</p>

This dissertation is an attempt to explore first year college students' Facebook use in association with their relationship development with their previously unacquainted roommates. Survey data indicated that it is very common for freshmen to look up their roommates on Facebook after receiving their roommate assignment from school. Being able to get an idea of who the roommate is helps reduce a student's uncertainty about living with a complete stranger. Both the uncertainty reduction theory (URT) and the predicted outcome value (POV) theory provide a solid theoretical framework to predict students' information-seeking behaviors on Facebook. Social information processing (SIP) theory and hyperpersonal model are proved to be helpful in explaining students' impression formation process on Facebook. This research predicts that information-seeking behaviors as well as the impressions formed based on information available on Facebook will reduce students' uncertainty about the roommates. Moreover, the study aims to take a further step by applying expectancy violations theory to investigate whether the discrepant impressions formed between Facebook and offline experience have an impact on students' level of uncertainty upon move-in with the roommates, and more importantly, the impact on the development of roommate relationship closeness. / A combination of a three-wave survey method and in-depth interviews with 19 students was used for this study. Survey data were collected at three different time points: (1) two weeks before college freshmen moved in with their roommates; (2) one week after they moved into the dormitory; and (3) seven weeks after living together with the roommates. The interviews were conducted after the three-wave survey was completed. / Statistical analyses using multiple linear regressions, multiple analysis of variance, and mixed-design ANOVA were applied for the hypotheses testing. The findings were mostly consistent with the hypotheses: (A) before moving in with the roommates, incoming first year students' uncertainty level was affected by how often they interacted with the roommates on Facebook, how many channels they used to communicate with the roommates, and their impressions of roommates' appearance and task attractiveness; (B) freshmen who formed positive initial Facebook impressions engaged in more information-seeking behaviors and had greater certainty than those who formed negative initial impressions of the roommates; (C) upon moving in with the roommates, students' uncertainty level was influenced by their offline impressions of the roommates' social and appearance attractiveness; (D) discrepancies between initial Facebook and offline impressions produced significant group differences in students' level of uncertainty and relational outcomes with the roommates; and (E) students' uncertainty and the impressions of roommates change over time and among groups.

This dissertation was situated in the crossroads of educational data mining (EDM), educational digital libraries (such as the National Science Digital Library; http://nsdl.org), and examination of teacher behaviors while creating online learning resources in an end-user authoring system, the Instructional Architect (IA; http://ia.usu.edu). The knowledge from data/database (KDD) framework for preparing data and finding patterns in large amounts of data served as the process framework in which a latent class analysis (LCA) was applied to IA user data. Details of preprocessing challenges for web usage data are included. A meaningful IA activity framework provided four general areas of user behavior features that assisted in the interpretation of the LCA results: registration and usage, resource collection, project authoring, and project usage. Four clusters were produced on two samples (users with 5--90 logins and those with 10--90 logins) from 22 months of data collection. The analyses produced nearly identical models with both samples. The clusters were named according to their usage behaviors: one-hit wonders who came, did, and left and we are left to wonder where they went; focused functionaries who appeared to produce some content, but in only small numbers and they did not share many of their projects; popular producers who produced small but very public projects that received a lot of visitors; and prolific producers who were very verbose, created many projects, and published a lot to their students with many hits, but they did not publish much for the public. Information about EDM within the context of digital libraries is discussed and implications for the IA, its professional development workshop, and the larger context of educational digital libraries are presented.

<p> Internet Memes transverse and sometimes transcend cyberspace on the back of impossibly cute LOLcats speaking mangled English and the snarky remarks of Image Macro characters always on the lookout for someone to undermine. No longer the abstract notion of a cultural gene that Dawkins (2006) introduced in the late 1970s, memes have now become synonymous with a particular brand of vernacular language that internet users engage by posting, sharing and remixing digital content as they communicate jokes, emotions and opinions. </p><p> For the purpose of this research the language of Internet Memes is understood as visual, succinct and capable of inviting active engagement by users who encounter digital content online that exhibits said characteristics. Internet Memes were explored through an Arts-Based Educational Research framework by first identifying the conventions that shape them and then interrogating these conventions during two distinct research phases. <?Pub _newline>In the first phase the researcher, as a doctoral student in art and visual culture education, engaged class readings and assignments by generating digital content that not only responded to the academic topics at hand but did so through forms associated with Internet Memes like Image Macros and Animated GIFs. In the second phase the researcher became a meme literacy facilitator as learners in three different age-groups were led in the reading, writing and remixing of memes during a month-long summer art camp where they were also exposed to other art-making processes such as illustration, acting and sculpture. Each group of learners engaged age-appropriate meme types: 1) the youngest group, 6 and 7 year-olds, wrote Emoji Stories and Separated at Birth memes; 2) the middle group, 8-10 year-olds, worked with Image Macros and Perception memes, 3) while the oldest group, 11-13 year-olds, generated Image Macros and Animated GIFs. </p><p> The digital content emerging from both research phases was collected as data and analyzed through a hybrid of Memetics, Actor-Network Theory, Object Oriented Ontology, Remix Theory and Glitch Studies as the researcher shifted shapes yet again and became a Research Jockey sampling freely from each field of study. A case is made for Internet Memes to be understood as an actor-network where meme collectives, individual cybernauts, software and source material are all actants interrelating and making each other enact collective agencies through shared authorships. Additionally specific educational contexts are identified where the language of Internet Memes can serve to incorporate technology, storytelling, visual thinking and remix practices into art and visual culture education. </p><p> Finally, the document reporting on the research expands on the hermeneutics of Internet Memes and the phenomenological experiences they elicit that are otherwise absent from traditional scholarly prose. Chapter by chapter the dissertation was crafted as a journey from the academic to the whimsical, from the lecture hall to the image board (where Internet Memes were born), from the written word to the remixed image as a visual language that is equal parts form and content that emerges and culminates in a concluding chapter composed almost entirely of popular Internet Meme types. </p><p> An online component can be found at http://memeducation.org/</p>

<p> The virtual 3D world of Second Life continues to grow as an educational platform for higher education. Instructional designers and faculty designers by assignment in this multi-case study described the constructivist instructional strategies, design models, and processes, utilized to create constructivist collaborative-learning environments in Second Life. A gap was identified in the literature surrounding the use of constructivist design and the effects on various alternative-learning environments, such as Second Life. Ten participants from higher education were purposively chosen to participate in the study. All of the 10 participants met the criteria that included five years experience in instructional design and two years experience designing in Second Life. Five participants were instructional designers and the other five were faculty designers by assignment. Data were collected from four sources that included in-depth semi-structured participant interviews, an observational protocol guide, and documents. The same observation protocol guide was used to examine Second Life sites while the participants were present. The study identified the instructional design models, processes, strategies, advantages, and challenges for instructional design in Second Life. Included in the findings is an instructional design model for use in virtual worlds such as Second Life. .</p>

<p> This study investigates how heterosexual young people understand and manage risks related to meeting sexual partners online in the United States. The purpose of this study is to help inform the development of culturally-appropriate sexual risk communication and health promotion messages for young people by linking public health knowledge of adolescent sexual health and eHealth with anthropological theories of risk. With qualitative data from two rounds of semi-structured interviews and two group interviews with university students in central Florida, this study shows how young people experience and prioritize more social-emotional risks in meeting online-to-offline sexual partners compared to physical risks. The prominence of these social-emotional risks implies the need for more health promotion messages that incorporate both physical and social-emotional health risk communication.</p>
