This three-manuscript dissertation examined the construct and predictive validity of the Community of Inquiry (CoI) framework through a factor analysis, meta-analysis, and thematic synthesis. Accordingly, the overall results provided conceptual and empirical insights into the construct and predictive validity of the CoI framework.

This study focuses on the potential contribution of new information communication technologies in higher education, in particular the use of microblogging, in transforming teaching practices to enhance critical thinking skills. Recognising the dearth of critical thinking skills in higher education and its importance in the cultivation of an engaged citizenry which is necessary for the creation of a vibrant and thriving democracy, the study seeks to investigate teaching practices in the higher education sector, utilizing the Community of Inquiry model to examine the possible iterative dialogues between lecturer and students in a first year class , in the form of microblogging posts , for evidence of potential critical engagement. In its finding , the study, whilst not being able to demonstrate significant evidence of higher order thinking, ascribed to the use of the of the microblogging activity , does however support the notion that the microblogging platform offers the potential for critical engagement but emphasizes that this potential , is to a very large degree, dependent on the adoption of appropriate and sound pedagogical strategies .

As mobile access and massive open online courses (MOOCs) become a global reality, the realm of potential distance learners is expanding rapidly. Mobile learning (mLearning) as well as MOOCs are based on similar characteristics as shown in the literature review of this study. They both enhance a community feeling, increasing networking and collaboration; they strengthen lifelong and informal learning, they use social media to a large extend and they are ideal for setting up communicative dialogues. The focus on learner interactions is of interest, as research has shown that dialogue is an important element for learning and knowledge enhancement, and mobile access increases the opportunities to enter into such interactions. This thesis study used a sequential explanatory mixed methods approach to investigate the impact of mobile accessibility on learner interaction in a MOOC. The study showed that opening up a MOOC for mobile access has immediate impact on learner interactions, as participants with mobile devices tend to interact more with their fellow learners in comparison to their non-mobile colleagues. This was deduced from the mixed methods approach looking at web-based statistics, an online survey, an analysis using the Community of Inquiry framework and one-on-one interviews with volunteers. The study formulated a set of 20 strategies and possible consequences deriving from the analysis of the impact of mobile accessibility in a MOOC and more specifically how this affects learner interactions. These strategies might optimize the impact of mobile access on learner interactions in an informal, open, online course. Future research needs to support the findings, embracing a larger learner population from a more varied background. Overall, this research hopes to add to the body of knowledge strengthening the field of distance education. / 2013-02

[pt] Este estudo tem por objetivo analisar o uso de neologismos da área da informática por grupos sociais que caracterizamos como comunidades de prática, tomando como caso exemplar as formas verbais printar e bugar, derivadas do inglês print e bug. Defendendo a hipótese de que os empréstimos são fenômenos linguísticos naturais e inevitáveis, tratamos a questão dos estrangeirismos, primeiramente, sob o ponto de vista histórico, e, posteriormente, como fenômeno gramatical exemplificado por essas novas formas verbais. Finalmente, a questão é considerada do ponto de vista social, buscando-se mostrar a participação das comunidades de prática na consolidação e extensão de significado das importações lexicais. / [en] This study aims to examine the use of neologisms loaned from the area of information technology by social groups characterized as communities of practice, taking as an exemplary case the verb forms printar and bugar, derived from the English words print and bug. Defending the hypothesis that loans are natural and inevitable linguistic phenomena, we treat the appropriation of foreign words initially from the point of view of history, and later as a grammatical phenomenon, exemplified by such new verb forms. Finally, the issue is considered from the social point of view, trying to show the involvement of communities of practice in the consolidation and extension of lexical meaning of loans.

Syftet med studien är att identifiera hur såväl framgångsrika förutsättningar som praktiska tillämpningarskapas av lärarutbildare när det gäller lärarstudenters digitala kollaborativa lärande i matematikundervisningpå distans. Studien genomfördes med utgångspunkt i ett aktionsforskningsarbete, därempirin inhämtades genom skriftliga reflektioner samt enkätfrågor av sluten och öppen karaktär. Iaktionsforskningsarbetet kombinerades ett konferensverktyg och en yta för samarbete online för attskapa en lärande gemenskap i matematikdidaktik inom högre utbildning. Med hjälp av ramverketcommunity of inquiry undersöktes studenters och lärarutbildares presence, närvaro, som uppstår iläromiljön online. När det gäller utvecklingen av kursdesign och innehåll går det att dra slutsatsen attcommunity of inquiry främst uppfyller cognitive presence medan teaching presence behöver förstärkas.När det gäller de känslor som lärarutbildare och studenter förnimmer vid kollaborativa kursmomenti matematikdidaktisk undervisning online går det att dra slutsatsen att både positiva och negativakänslor kan gynna lärandet. Det behövs insatser för att bemöta frustration i olika former hosbåde studenter och lärarutbildare. / The purpose of the study is to explore how helpful conditions such as practical applications are createdby teacher educators regarding student teachers' digital collaborative learning in online mathematicseducation. The study was carried out based on an action research project, where the empiricalevidence was obtained through written reflections and survey questions of a closed and open nature.In the action research a conference tool and an online collaboration surface were combined to createa learning community in mathematics didactics online in higher education. Using the community ofinquiry framework, the presence of students and teacher educators in the online learning environmentwas investigated. When it comes to the development of course design and content, it can beconcluded that the community of inquiry primarily fulfils cognitive presence while teaching presenceneeds to be strengthened. When it comes to the emotions that teacher educators and students feelduring collaborative course elements in online mathematics didactic teaching, it can be concludedthat both positive and negative emotions can benefit learning. Efforts are needed to respond to frustrationin various forms among both students and teacher educators.

Enhanced innovative learning through the purposeful development of effective blended teaching and learning environments supported by a variety of interfaces is a strategic focus of the NWU and specifically the Faculty of Educational Science. There are several emerging models to ensure effective online and blended learning but the prominent model that has attracted attention is the Community of Inquiry (CoI) framework developed by Garrison, Anderson and Archer in 2000. The CoI framework is conceptually grounded in theories of teaching and learning in higher education and is consistent with John Dewey’s work on community of inquiry. CoI is deeply rooted into pragmatism as is evident in Dewey’s argument where he explains the idea of extracting meaning from experience. The focused of this study was on blended learning in a graduate teacher training course in Technology Education. The content of Technology as a subject is derived from other disciplines such as science, engineering and design. Due to the unique features of Technology as a subject, it was of great value, within this applied discipline, to investigate the unique patterns and relationships occurring among CoI presences in such a module of a teacher training graduate course. The purpose of the study was to:  develop an understanding of how the three presences (teaching presence, social presence and cognitive presence) in CoI enhance online learning;  investigate the extent of CoI in a blended mode of delivery within a TE graduate course; and  develop, implement and evaluate a module for a graduate course in Technology teacher training for a blended mode of delivery, based on requirements for the development of CoI. A design-based research methodology approach was followed for this study and included qualitative and quantitative methods in a multi-strand design. Design-based research is intrinsically linked to, and developmentally nourished by, multiple design and research methodologies, which utilises many data collection and analysis methods and which makes it suitable for a mixed method research. Findings from the literature review on the value of CoI for the effectiveness of online learning indicated that blended learning is dependent on the ability to facilitate a CoI. It is through the application of the principles for CoI that a successful transition from a face-to-face to a blended mode of delivery for the applied subject TE was possible. Findings with regard to the extent to which CoI manifested itself in this Technology graduate course indicated that teaching presence manifested itself to a good extent in the TE undergraduate course. The main findings that were of concern with regard to teaching presence included: insufficient clear instructions and communication, feelings of isolations and disconnectedness, lack of immediacy and the inability to connect online feedback to lecturer expertise. Although social presence did manifest itself to some extent in the TE undergraduate course, it was the hardest to establish out of the three presences. The main issues arising from the manifestation and existence of social presence included: insufficient sense of belonging in the online environment, students didn’t feel comfortable expressing themselves affectively as well as uneasiness to communicate, interact and participate online with other module participants. Finally, cognitive presence did manifest itself to a satisfying extent in the TE undergraduate course. Findings suggest that there was a not sufficient structured triggering events to create a sense of puzzlement which suggests that more activities must be included that will encourage reflection and therefore will improve the movement through the cognitive inquiry process. Other findings from the study indicated that students experienced time management and the coordination and management of group activities as challenging. These challenges experienced by students reflect a lack of self-regulation skills in learning presence. Other challenges included that students experienced in the online environment of blended learning included: accessibility, lack of technology skills and the newness of blended learning. Design principles for the manifestation and existence of CoI for effective learning within a TE graduate module were establish for teaching presence, social presence and cognitive presence. The research contributed to the field by reporting on the process of how CoI can be enhanced in a blended learning environment for a complex subject such as Technology, and by providing evidence based guidelines for the design and implementation of blended learning with CoI principles as guidelines. / PhD (Curriculum Development Innovation and Evaluation), North-West University, Potchefstroom Campus, 2014

Most research on Cognitive Load Theory (Sweller, 1988) has uncovered many instructional design considerations for learning complex tasks. Additionally, the Community of Inquiry (Garrison, Anderson, & Archer, 2000) framework describes many of the learning experiences in online education. A gap existed in the literature for investigating cognitive load over the duration of a college algebra course and for investigating the relationship between cognitive load and cognitive presence. This research study has addressed this gap by investigating cognitive load and cognitive presence in an online and face-to-face college algebra course. The results of this study revealed that face-to-face students earned statistically significant higher final course grades and homework grades than the online students. The face-to-face math course was slightly more efficient because it produced learners who exerted similar cognitive load as learners in the online course but the learners in the face-to-face earned higher performance score. Online discussion prompts that ask student to apply their solution or defend their solution engaged students in cognitive presence differently. When students were prompted to apply their solution to a real world scenario, most students reached resolution in their initial posts, but they were often not cognitively present in their follow-up posts. When students were prompted to provide a defense of their solution, most of the posts demonstrated cognitive presence, but not as many individual students reached resolution. Additionally, students progressed through the stages of cognitive presence when an instructor asked them a specific question about their math problem or real life scenario in a timely manner. When instructors post questions to their students that directly ask for an application of their hypothesis or an explanation how they arrived at their hypothesis, students can reach the highest stage of cognitive presence. When instructors post messages that reach the highest stage of cognitive presence, students do not post messages that reach the highest stage of cognitive presence. Lastly, this study did not find a strong linear relationship between cognitive presence and cognitive load.

Doctor of Philosophy / Department of Educational Leadership / W. Franklin Spikes / This research examined the nature of the patterns of communication of discussion board users who were enrolled in undergraduate level online courses. For purpose of analysis, this study used Norman Fairclough’s Critical Discourse Analysis (CDA) framework (1992). Data were collected from discussion board posts of eight undergraduate online courses that were offered by a small, private, religiously-affiliated, liberal arts university. An examination of these data was further informed by Garrison, Anderson, & Archer (1999) Community of Inquiry model. Using Garrison et al.’s ideas, the researcher described the nature of the interactions between students and faculty with respect to social, cognitive, and teaching presence in online discussion boards. The findings of this research suggest that understanding the presence of social, cognitive, and teaching presence as well as the nature of the patterns of communication in the discourse is important in developing quality distance education discussion boards. More specifically, they showed that evidence of social and teaching presence was regularly present in an examination of the online discussion boards. Conversely, the data showed very few examples of cognitive presence. Based upon the findings of this research, ideas for how constituents of online education can continue with and improve upon the practices found here relative to social and teaching presence as well as how to re-envision and improve upon cognitive presence and overall-intention for discussion boards were also offered.
