abstract: The purpose of this action research study was to measure the transactional distance of computer science students who participated in an online virtual community after completing a college preparation program. Using data and results generated from previous cycles of research I developed and moderated an online virtual community designed to lessen transactional distance using a sequential exploratory mixed-methods research design. This study addressed the following research questions: 1. How and to what extent will participation in a virtual community influence the transactional distance between students and course content? 2. How and to what extent will participation in a virtual community influence the transactional distance between students and their instructors/teaching assistants? 3. How and to what extent will participation in a virtual community influence the transactional distance between students and other students in the same courses? The participants for this action research study included approximately 200 students enrolled in six online sections of an entry level computer programing course from various locations around the world. Also participating in the community were the online instructors who taught the course, teaching assistants, advisors, and the action researcher. Using the sociocultural, transactional distance, self-determination, and adult learning theories as a framework, the virtual community provided occasions for students and instructional team members to share experiences and support each other academically and socially. The community was designed to enable students to give and receive frequent feedback, increase autonomy and their sense of belonging, and provide additional opportunities for them to learn from each other. Through a descriptive analysis of the transactional distance survey results, I was able to determine that transactional distance between students and their teachers, and students the course content slightly increased, while the transactional distance between students and their classmates somewhat decreased. There was also an increase in average final grade and pass rate and a decrease in student withdrawal rate. / Dissertation/Thesis / Doctoral Dissertation Educational Leadership and Policy Studies 2018

Historically, disabled people have not been viewed as innovators of humor because disability is associated with tragedy. My dissertation challenged the association of disability with tragedy by positioning disabled comedians as educators and ambassadors of disability rights. I reviewed the literature on disability and humor as well as disability oppression, which disability humor challenges. I used phenomenology as well as culturally responsive methodologies to examine what disabled comedians are achieving with their humor and what nondisabled audience members learned from attending their performances. Vygotsky’s sociocultural theory of learning was used to examine learning outcomes for audience members. I examined historical and contemporary Black humor, which is much older than disability humor in order to investigate what may be the future of disability humor.

Due to recent developments in Web 2.0 technologies, computer-mediated collaborative writing has captured the growing attention of second language researchers and instructors. The affordance of wikis for collaborative writing has been hailed, but few studies have explored the nature of wiki collaboration and interaction during small group writing using wikis. This dissertation investigated dynamic group interactions in wiki-based collaborative writing tasks in an English for Academic Purposes (EAP) course at a southeastern public research university in the U.S. A total of twenty-nine English as a Second Language graduate students collaboratively worked on two writing tasks within small groups in Wikispaces sites. By adopting a multiple-case study approach, I closely examined four small groups that had diverse L1 background composites and presented a comprehensive picture of students' wiki-based collaborative writing. Informed by sociocultural theory, particularly the notions of scaffolding and zone of proximal development, I explored small group interactions to derive how they negotiated writing tasks, co-constructed writing, and mutually scaffolded wiki writing processes. I also examined what factors mediated the dynamic interactions, and in what ways the interactions influenced wiki writing products and connected with students' reflections about wiki collaborative writing. The triangulated data sources included archived wiki "Discussion," "Comments," "History," and "Page" records, pre-task and post-task questionnaire surveys, post-task and follow-up interviews, students' reflection papers, instructors' assessment of students' wiki group writing, and my research logs. In terms of the data analysis, I mainly conducted qualitative procedures using constant comparative method and content analysis, supplemented with descriptive analysis. The results revealed that the four small groups demonstrated four characteristic patterns of interaction. The patterns were not static across two wiki writing tasks. Mixed patterns were found in Group 1 (Collective-- Active/withdrawn) and Group 3 (Dominant/defensive-- Collaborative). Group dynamics were also evident in Group 2 (Expert/novice) and Group 4 (Cooperating in parallel). These patterns were featured with language functions that small groups performed while negotiating writing tasks, writing change functions that they performed while constructing joint texts, and scaffolding strategies that they applied throughout collaborative writing processes. In addition, multiple factors mediated small groups' wiki interactions: motives/goals, agency and emotion, and prior experiences in such aspects of cultural background, small group work, and technology use. Moreover, the group interactions had influences on joint wiki writing products and also connected with students' reflections about wiki affordances and their learning experiences. This study bridged the gap in computer-mediated collaborative writing research, and also shed new light on the networked writing pedagogy in the EAP context.

The purpose of this exploratory study was to examine the actions of online language learners from an activity theoretical perspective. It also attempted to explain how the students' learning outcomes evolved from their online learning experiences. This explanation placed an emphasis on the learners' previous experiences, defining their activity systems, the use of mediational tools, and the resolution of contradictions. Within this activity theoretical case study a background survey, four interviews, and three field observations were conducted with seven foreign language students of an online Spanish course. The students' on-screen actions were recorded and subsequently documented in a video episode log. This log, the background survey, and the interview transcripts were coded for the a priori categories established in the research questions and for emergent themes. Seven mediational tools were identified, including a widespread use of online dictionaries and translators. The students attempted to use the mediational tools to gain control over their online language learning; however, as exhibited by the students' varying levels of regulation, some students were unable to reach or maintain self-regulation while using computer-based tools. In addition, the nature of the mediational tool use appeared to be influenced by the variety of linguistic backgrounds. Three levels of contradictions were identified including: conflicting-object contradictions, inter-activity contradictions, and technology-related contradictions. The findings of this study indicated that contradictions may be invisible to the subject of the activity. Furthermore, it was noted in this research that some students may have the capacity to identify the contradiction, yet they may not have the desire or motivation required to make the necessary change to further learning and development within the activity. Thus, contradictions may not always be resolved even when they are visible.

Since the mid 90s, an increasing number of researchers have adopted a sociocultural theory (SCT) of mind to investigate the social and cognitive functions of language during learner-learner interaction (Lantolf & Thorne, 2007). Researchers from an SCT perspective have identified that first languages (L1s) serve important cognitive functions (Alegría de la Colina & García Mayo, 2009; Storch & Aldosari, 2010). Swain and colleagues (Swain, 1995; Swain & Lapkin, 1995, 1998) have also illustrated that languaging, a form of verbalization, facilitates the completion of complex linguistic tasks which leads to second language (L2) development (Swain, Brooks, & Tocalli-Beller, 2002). Moreover, researchers have found that task type impacts language development (Storch & Aldosari, 2010; Storch & Wigglesworth, 2003; Swain & Lapkin, 2001). Due to the growing number of multilingual learners in the world today (Hammarberg, 2010), researchers need to expand the scope of the research to include the role(s) of native and nonnative languages on third language (L3) development. Thus, the purpose of the current multiple case study was to investigate the specific mediating functions of multilingual learners’ languages during four types of collaborative tasks and to explore the relationship between languaging and L3 development. A 16-week classroom-based study was conducted in a university French as a foreign language classroom in Mexico with four focal participants. The language produced during learner-learner interaction was examined using three types of analysis: (1) each turn was coded for language and for their specific functions; (2) each Language-Related Episode (LRE) was coded for type and for resolution; and (3) accuracy on individual tailor-made posttest items. Findings uncovered a complex picture of task type effects on the specific mediating functions of language as well as complementary functions of L1 and L3 mediation. Results from the analysis of LREs show that task type impacts the occurrence and resolution of LREs. Accuracy scores from the posttests suggest that L1 and L3 mediation promotes L3 development. Findings are in line with the focal participants’ beliefs. The findings that languages serve various social and cognitive functions during task completion are discussed in light of current ideas from an SCT perspective.

“IF I AM LOSING THEM, I’M GOING TO CHANGE. SO THAT’S WHAT WE DID!”: THIRD GRADE TEACHERS CONTEMPLATE THE LITERACY NEEDS OF DIVERSE STUDENTS WITHIN A TEACHER STUDY GROUP by Megan A. Nason According to Birchak, Connor, Crawford, Kahn, Kaser, Turner, & Short (1998), Fang, Fu, & Lamme (2004), Kennedy & Sheil (2010), and Wiliam (2008), teacher study groups can provide a supportive and collaborative professional development environment. The purpose of this study was to examine the professional development experiences of three third grade teachers working with culturally, linguistically, and economically diverse (CLED) students in a high-needs school as they participated in a teacher study group. The adoption of national standards and pressures for all students to achieve high standardized test scores in math and reading due to Adequate Yearly Progress (AYP) requirements mandated by the No Child Left Behind Act (2001) resulted in increased stress, anxiety, and uncertainty for the teachers participating in this study. The following research questions guided this qualitative, ethnographic case study: (1) In what ways does participation in a teacher study group impact elementary teachers’ knowledge, beliefs, and understandings when teaching culturally, linguistically, and economically diverse students in a high-needs school? (2) In what ways do teachers’ literacy practices shift as a result of engaging in teacher study groups focused on issues related to culturally, linguistically and economically diverse student populations? Bronfenbrenner’s (1979; 1994) ecological models, Vygotsky’s (1978; 1986) sociocultural theory, and Ruddell and Unrau’s (2004) sociocognitive reading model served as theoretical frameworks that informed this naturalistic inquiry. Through constant comparative analysis (Glaser and Strauss, 1967) of data collected through pre- and post-interviews, bi-weekly teacher study group meetings, and classroom observations, the teachers’ knowledge, beliefs, and understandings about how culturally, linguistically, and economically diverse (CLED) students learn and develop literacy skills were explored. The findings of this study demonstrate how teacher study groups can provide teachers with a safe space to build trusting relationships so that they can discuss school and classroom-related uncertainties, vulnerabilities, frustrations and successes. Shifts in enacted curriculum, instruction, and beliefs occurred as the teachers in this study attempted to negotiate their beliefs about how CLED children learn through engaging in conversations related to integrated curriculum, higher-order thinking, inquiry-based learning, literacy instruction, literacy development, and the diverse needs of their students.

In this essay I examine if socio cultural theory is present for teachers when pupils and students are using computers in class, especially when using blogs as a tool for learning. The aim of the essay is also to examine if blogs among pupils in class can promote peer support, co-operation and reflective dialogue, and in that case in what way. The essay consists of two studies, one small interview study and one literature study.  The interview study is made with the qualitative method phenomenographic analysis, presenting four Swedish teachers who have much experience using blogs in education. The aim of the literature study where some national and international research studies of relevance are presented, is to broaden the perspective. The result of the interview study shows that a socio cultural theory is highly present among the teachers who already use blogs in education. In addition, those teachers experience that the blog in the classroom supports dialogue and co-operation among the pupils.  In contrast, the literature study shows that most teachers in Sweden who made their pupils work with computers in classroom seem to let their student work alone, without guiding them and without creating co-operation or dialogue in the classroom. Furthermore the literature study shows that there are many things teachers can do to improve their student to co-operate and reflect critically on a blog. One example is teachers in Taiwan who used themselves as role models by reflecting on their own teaching when blogging openly in front of their students. This encouraged their students to reflect critically concerning their own development.

Kunskapsbedömningar i träningsskola ska utgå från en läroplan utformad specifikt för elever i träningsskola. Den ska utgå från elevens förutsättningar. Syftet med denna studie är att låta lärare i träningsskola beskriva hur de utför kunskapsbedömningar. I studien beskriver lärare sitt arbete med kunskapsbedömningar i träningsskola. Studien beskriver också vad lärare använder för verktyg och vilken betydelse de anser att kunskapsbedömningar i träningskola har. Studien bygger på kvalitativa intervjuer med sex lärare som arbetar i träningsskola. Analysen är gjord utifrån sociokulturell teori. Resultatet av studien visar att elever i träningskola har behov av en egen läroplan. Studien visar också att formuleringar av målen i kursplanen är viktiga för att kunskapsbedömningarna ska ha så hög validitet som möjligt. Lärarna bör också ha en helhetsbild av eleven och möjlighet till ett gemensamt kommunikationssätt för att öka validiteten. / Knowledge assessment in special school for pupils with severe learning disabilities shall be based on a curriculum designed specifically for this type of school. The assessment shall be made taking into account each pupil´s individual prerequisites. The purpose of this study is to let teachers in special school describe how they make knowledge assessment, what implements they use and what importance knowledge assessment in special school has, according to them. The study is based on qualitative interviews with six teachers working in special school. The analysis was then made from sociocultural theory. The results show that pupils in special school need their own curriculum. The results also show that the wording of the curriculum is important to get as much validity as possible of knowledge assessment. Teachers should also have a complete picture of the pupil and a common approach to communication to increase the validity.

This study investigated collaborative online reading from a Sociocultural Theory (SCT) perspective. Building on, yet transcending, research into learning strategies, the research focused on the concepts of mediational tool use, strategic behavior, and patterns of dialogic engagement of college student dyads as they completed a series of three collaborative WebQuests in a beginning German as a Foreign Language (GFL) class. On-screen actions and verbal interaction of six dyads of beginning GFL students were recorded during three short-term, collaborative WebQuests. Full motion screen recordings were transcribed, and relevant episodes were coded for mediational tool use and strategic behaviors. All dyads used their L1 as well as the L2 in mediating task success. The distinction between L1 and L2 was fluid, as students accessed a combination of psychological tools according to their own goals, ability, and orientation. Although the L1 was the dominant tool employed by the participants in this study, over time some students were able to use the foreign language as a psychological tool for completing the assigned task. Eleven combinations of mediational tool use were identified and related to levels of regulation. Students strategic behaviors fell into five categories: affective, contextual, socio-procedural, cognitive, and other. The ratio between constructive and destructive strategic behaviors provided insight into the overall collaborative climate. Cognitive strategies were further divided into three theoretically salient categories: mediation a student s own regulation of L2 tool use, mediating the partner s regulation of L2 tool use and mediating collective regulation of L2 tool use. Student dyads exhibited high frequencies of both self-mediation and collective mediation, which indicates that these students were working in their own and their partner s zone of proximal development. The nature of the dialogic engagement varied by dyad, but remained relatively stable over time. Students goals and orientation towards the task impacted their overall collaboration. The role and development of L2 proficiency warrants further investigation. In peer collaboration, more symmetric dyad constellations may lead to more collective scaffolding and more positive dialogic engagement.

The purpose of this study was to investigate the potential use of Second Life (Linden Labs, 2004) and Skype (Skype Limited, 2009) as simulated virtual professional development tools for pre-service teachers seeking endorsement in teaching English as a Second Official Language (ESOL. Second Life is an avatar-based Internet program that allows end-users to interact, using audio and chat features, with a digital representation of themselves (an avatar). Skype is an Internet-based video conferencing program that allows users to see each other by way of a webcam. Of particular interest to this study was how a group of 12 pre-service teacher education students internalized professional knowledge and if that knowledge was actually transferred into active teaching practice and professional identity development. To investigate this knowledge transfer, an exploratory case study (Yin, 2008) was conducted framed around the theories of sociocultural constructivism (Kanuka & Anderson, 1999; Vygotsky, 1978) and critical pedagogy (Freire, 1990). The components of one module from the ESOL II course that addressed hegemonic curriculum and teaching practices were recreated in Second Life and Skype or analysis. Using within-case analysis (Miles & Huberman, 1994), vignettes (Ely, Vinz, Downing, & Anzul, 1997; Spalding & Phillips, 2007), and tallied collaborative utterances (Erben 2001), developmental progressions among the pre-service teachers were examined from the beginning to the end of the module and were evaluated for their relevance to knowledge transfer and self-regulation. The interactions were also examined for instances of amplifications and reductions of pedagogic practices (Erben 1999) through collaborative dialogue (Bakhtin, 2006; Erben, 2001; Wertsch, 1991). The findings of this study suggested the positive potential of using Second Life and Skype to enable self-regulation and pedagogic transformations to occur among the participants with appropriate considerations acknowledged for the teaching audience, developmental goals, and venue of instruction.
