After Norton Peirce's (1995, Norton, 2000) groundbreaking work in conceptualizing identity as "multiple, changing, and contradictory," many researchers have explored language learners' identities. However, few studies of identity have been conducted within the "overlooked and understudied" (Mathews-Aydinli, 2008) context of adult community ESL (English as a Second Language), and even fewer studies have focused on LESLLA (low-educated second language and literacy acquisition) learners in mainstream community ESL programs. This thesis, based on a case study of an adult LESLLA learner in a community ESL class, analyzes how this student's identity, the social context of her life, and the classroom space shaped her investment in participating in the ESL class. Ethnographic interviews revealed that the participant's investment in language learning was linked to her identity in multiple and contradictory ways: while the participant eventually left the ESL program, her self-identification as 'no preparada' (uneducated) and therefore 'burra' (stupid) seemed to be a motivating challenge, not an insurmountable obstacle, and her sense of investment in language learning remained strong even though her in-class participation was limited. The results have pedagogical as well as theoretical implications: there is clearly value in engaging learners' lives in the classroom as well as including learners' voices in research to have a clearer recognition of how learners see themselves and their "possible selves" (Dornyei, 2009) to be able to understand the complex factors that underlie their investments in language learning.

This thesis comprises a critical review and suggestions for enhancement of the Community of Inquiry Framework (CoIF), the frequently cited model of collaborative community-based online learning. It combines a systematic engagement of relevant literature and research, with the application of the CoIF thinking to six of my peer-reviewed publications. Although not initially conceived as forming part of a doctorate submission, these publications are drawn upon throughout this narrative, to assist my interrogation of the CoIF. They are also used to provide evidence of my continuing journey as an education researcher. This thesis is therefore not an exegesis – a traditional meta-narrative encompassing this candidate’s publications. It moves beyond my findings in the publications to create and present supplementary concepts, and develop pointed guidance about using the Framework in supporting online learning in tertiary education. My review first critically interrogates the three constituent elements or Presences of the CoIF. Social presence emerges as a highly complex and multi-faceted construct, in which the de-emphasising of the affective in the CoIF seems at variance with current research reporting the strong student emotional response to working online, and particularly in collaborative, community-based groupings. Then, in Cognitive presence, there has been little consideration of, and specificity about, reflection in the CoIF. My critique proposes that reflection and critical thinking are distinct but inter-related concepts; both of which need to be addressed. Teaching presence is renamed ‘Tutoring presence’ informed by my review based upon my emergent understandings of student-centred learning. Two enhancements to the CoIF are then proposed, together with the rationale for establishment of a Tutors’ Network. The first enhancement, referred to as 'the Influences,’ unites and enriches the individual Presences. The second argues for the existence and use of a personal learning retreat at the heart of a community of inquiry, addressing a perceived omission in the CoIF. This learner ‘space’ provides a ‘quiet, safe place’ for the private (internal) world of the learner, as a foil to the shared collaborative space in the CoIF (the external world). Finally, a Tutors’ Network is outlined as a vehicle for advancing their understandings and knowledge of online, collaborative, community-based learning in general, and in particular of communities of inquiry. This should develop the abilities of online tutors, improve their learners’ educational experiences and encourage research and scholarship into the CoIF.

This thesis considers a theoretical tradition which is concerned with how adult literacies education might not always serve to socialise students into existing society, instead encouraging possibilities for desirable alternatives to it. Without this possibility, adult literacies education might only be understood as a socialising machine that slots students into society as it stands and where the role of research is to describe its operation. My research describes a long-standing refusal by educators, researchers and students to accept this possibility and my thesis continues this tradition. Through the analysis and interplay of the work of Pierre Bourdieu, James Paul Gee, Paulo Freire, Jacques Rancière, I distinguish between empowerment and emancipation in the context of literacies education. I set out the assumptions that Bourdieu and Gee make, how they understand power, identity, discourse and oppression, and what this means for the practice of an empowering adult literacies education. I also present assumptions made by Freire and Rancière, how they understand equality and oppression, and how an emancipatory literacies education might be understood and practiced. In particular, I describe how education for ‘empowerment’ encourages practices underpinned by the assumption that ideological processes prevent students from understanding how oppression is manifested. In contrast, I describe how an emancipatory education implies enacting educational relationships that are not reliant on this assumption, whilst exerting a social response to societal oppression. I make three claims. Firstly, that the idea of an emancipatory literacies education has come to be neglected or conflated with the idea that literacies education might empower, which has come to hold great sway. In so doing, I critique Freire’s work whilst reclaiming it as an emancipatory project. Secondly, that the educational practices associated with adult literacies for empowerment can be understood to encourage the socialisation of students into society as it stands. This emphasises the importance of distinguishing between empowerment and emancipation in the context of adult literacies education. Finally, that emancipation is a notion that must continue to be questioned and explored if educators, students and academics are to take responsibility for the practice of adult literacies education and its consequences. An emancipatory literacies education cannot be reliant upon the assumption that discourse is inherently ideological. Instead, it is predicated upon teachers and students assuming that emancipation is possible and acting on that assumption.
