The impact of Internet technology on critical thinking is of growing interest among researchers. However, there still remains much to explore in terms of how critical thinking can be fostered through online environments for higher education. Ten years ago, Garrison, Anderson, and Archer (2000) published an article describing the Community of Inquiry (CoI) framework which provided an outline of three core elements that were able to describe and measure a collaborative and positive educational experience in an online learning environment, namely teaching presence (design, facilitation, and direct instruction), social presence (the ability of learners to project themselves socially and emotionally), and cognitive presence (the extent to which learners are able to construct and confirm meaning through sustained reflection and discourse). This dissertation extends the body of research surrounding the CoI framework and also the literature on developing critical thinking in online environments by examining and exploring the extent to which teaching and social presence contribute to cognitive presence. The researcher was able to do this by offering 189 learners enrolled in 10 research methods courses and educational research courses an opportunity to use an innovative online resource (Research Design Learning Resource – RDLR) to assist them in learning about educational research and developing research proposals. By exploring how participants used this resource the researcher was able to gain insight into what factors contributed to a successful online learning experience and fostered cognitive presence. Quantitative and qualitative research approaches (mixed methods) were used in this study. The quantitative results indicated that both social and teaching presence had a strong positive relationship with cognitive presence and that learners generally perceived to have a positive learning experience using the RDLR. The qualitative findings helped elaborate the significant quantitative results and were organised into the following themes: making connections, multiple perspectives, resource design, being a self-directed learner, learning strategies, learning preferences, and barriers to cognitive presence. Future directions for critical thinking in online environments are discussed.

Significant research has investigated Jack Gibb’s model of defensive and supportive communication, but little has explored the influence of the type of talk -- defensive or supportive -- on perceptions of communication climate and the role that verbal aggressiveness may play in influencing both the types of talk and these perceptions. This thesis explored the relationship between defensive and supportive talk, verbal aggressiveness and communication climate using a mixed-method approach. Specifically, the Verbal Aggressiveness Scale was used to group participants for a dyadic problem solving exercise which generated conversational data that was analyzed qualitatively. Then, the Communication Climate Inventory was used to measure participants’ perceptions of the communication climate that emerged in their problem-solving dyad. The findings highlight factors that may influence the perception of communication climate. Examples of supportive talk that builds positive communication climates and limits the effects of verbal aggressiveness and examples of defensive talk that leads to negative communication climates are provided. This research demonstrates that language has an influence on communication climate through the words that shape the complex ways people perceive and understand each other and, interestingly, that the negative impact of defensive communication overrides the positive impact of supportive communication on the emergent communication climate.

This thesis examines the impact of the housing experiences of resettled refugees. It reiterates that becoming a refugee was not a matter of choice, but for those in refugee situations it was imperative to seek refugee status for their survival. This study focuses on the housing experiences of the Auckland Somali resettled refugees and seeks to identify the effect of housing policy and provision in Auckland. It also demonstrates the links of housing to employment, education and health. Refugees face considerable resettlement challenges based on differential factors such as ethnocentrism, immigration status, household composition and socio-economic conditions. These barriers are exacerbated by a lack of English language proficiency, a variety of educational backgrounds and unfamiliarity with institutional practices, especially during their early years of adaptation as relative newcomers to New Zealand.The vulnerable position of this group in housing markets requires up to date information to increase the provider's awareness of housing experiences and their impact on the resettlement process. In turn, an increased knowledge allows evidence-based decisions for appropriate intervention, policy, and strategy developments to facilitate optimum resettlement outcomes. Policy formulation and effective implementation must focus on the identification of suitable services to address the specific barriers experienced by this group. The empirical evidence supports previous findings that there were close correlations between the participants housing experiences that are the types of housing they occupied and their income.The study developed and implemented a Participatory Research Design involving a case study approach with multiple data collection methods. The primary field data was collected from focus group participants through a workshop of qualitative discussion and a survey.
