Item Preparing pre-service mathematics teachers to teach in multilingual classrooms : a community of practice perspective.(2013-10-01) Essien, Anthony AnietieThis study takes a particular look at mathematics teacher education communities of practice (CoPs) in order to provide rich descriptions of the CoPs and make claims about its relation/in relation to teacher preparation and particularly the preparation of preservice teachers for teaching mathematics in multilingual classrooms. The three dimensions of communities of practice proposed by Wenger (mutual engagement, shared repertoire and joint enterprise) were used in conjunction with Mortimer and Scott’s notion of meaning making as a dialogic process as a theoretical lens to gain an entry into the nature of communities of practice in pre-service mathematics teacher education classrooms. Data was collected through pre-observation interviews of 12 teacher educators at four Universities in one Province in South Africa in Phase One of the study. A methodological approach based on Wenger’s CoP theory and Mortimer and Scott’s dialogic process was developed and used to analyse classroom observation videos of four of these teacher educators’ classroom communities of practice in two universities in Phase Two of the study. Using the privileged practices in the CoPs as points of departure and how these practices shaped and were shaped by other dynamics in the CoPs, the findings emerging from the study indicate that within the multiply layers of teacher education, there is an overarching emphasis given to the acquisition of mathematical content. Nevertheless, the communicative approaches and patterns of discourse used by the different teacher educators opened up different possibilities as far as preparing preservice teachers for teaching (in multilingual classrooms) is concerned. Wenger’s community of practice theory has found applications in different spheres of life and in different organisational and educational settings. Its use to understand and describe mathematics pre-service classrooms is, however, still largely unexplored. A theoretical contribution that this study makes lies in the extension of Wenger’s CoP theory to include dialogic processes. A methodological contribution lies in the development of an organisational language (based on Wenger’s three dimensions of CoP) to characterise pre-service teacher education classrooms.Item Personal histories as a component of an ethnography of expert assessment practice in the workplace.(2012-03-12) Msimango, Sindiswa NontembisoThis research report describes the learning histories of computer assistants and expert assessment practice. This takes place in a workplace where computer training, specifically the fixing of hardware (CPU) occurs. It is hoped that the evidence collected might contribute towards the recognition and understanding of tacit assessment on the National Qualifications Framework, (NQF). In uncovering these learning histories and expert assessment practices, a component of ethnography which involves case history interviews and discussions was used. The theoretical framework used was situated learning theory and the legitimate peripheral participation of the computer assistants. This framework is itself embedded in the theory of constructivism. Case histories used as a component of ethnography is part of a bigger ethnographic project developed by the South African Qualifications Authority (SAQA). This particular study will contribute along with other projects in the University of Witwatersrand research group, to make up a full ethnographic account of learning and assessment in the workplace.Item The experience of becoming a PHD.(2012-02-28) Hadingham, Jennifer AnnThe development of the next generation of researchers is a priority if South Africa is to make a significant contribution to the international knowledge economy and establish itself as a force to be reckoned with in international research circles. In the context of this knowledge economy, researchers are increasingly being recognised as agents of economic growth. In order to be competitive, therefore, an extensive pool of active researchers needs to be cultivated. One way of doing this is to promote and develop doctoral capacity at the country’s universities. This entails, among other things, a move away from the traditional focus on what the supervisor does, to a more student-centred understanding of how the doctoral candidate experiences the process, and by implication, how this impacts on their research contribution. In this qualitative study, thirty doctoral candidates from the Faculties of Science and Humanities at the University of the Witwatersrand, Johannesburg, were interviewed in order to establish firstly, how they had experienced their supervision at this level, and secondly, whether or not these experiences had influenced the successful completion of their doctorates. One of the principal findings of the research was that the role of the supervisor was not central to the achievement of their degree; rather, many of the doctoral candidates asserted a significant level of agency in both identifying and making contact with experts beyond their university-appointed supervisors in order to supplement their access to relevant knowledge. In the majority of cases, this was encouraged by the supervisors. Such enterprises represent a marked departure from the traditional models of supervision in the Science and Humanities faculties. In the case of the former, the customary co-supervision arrangement is increasingly being augmented by student-initiated collaboration with authorities located outside the formal boundaries of the institution. The traditional Humanities model of supervision is also transforming from a one-on-one relationship to a style characterised by multiple supervisors, each from separate but cognate disciplines. The research suggested that these emergent models are eclipsing their predecessors as doctoral candidates increasingly recognise the value of extending the breadth of their disciplinary exposure beyond the confines of the university.Item From ideal into practice : an illuminative evaluation of a learnership in the insurance and investment sector.(2012-02-15) Sosznianin, TatianaThis study explores what happens as the ideals of a learnership, envisioned in the South African legislation, become real practice in a workplace within the financial services industry. Learnerships are at the centre stage for illuminating the processes of acquiring a vocational qualification, which combines education with work readiness. The constructivist philosophy to this research and its qualitative paradigm resonates well with the postmodernist thinking that knowledge has different purposes strongly linked to performance, demanding education that is value adding. It is through this postmodern lens that the broad theoretical framework for study is located. It encompasses theories of learning and workplace learning, such as Wenger’s (1998) perspectives on communities of practice and Kolb’s (1984) experiential learning circle. Mezirow’s (1981) transformative learning theory adds the dimension of dialogue. The method of illuminative evaluation is used to examine one event in order to explore its contextual insights. Qualitative inquiry has a fundamental people orientation and, for this reason, observation adds depth to the information gathering possibilities of interviews and document analysis. This report is enriched by narratives of people’s perspectives on events. This illuminative evaluation brought out rich and varied insights into the acquisition of knowledge, skills and work identity (values and attitudes), with some surprising and unexpected insights on success and failures. The workplace’s control of the learning process, while impacting extremely positively on the quality of the theoretical learning (which is interesting as education is not its core purpose), compromised in some respects the success of the end product of the learnership, the work readiness and employment possibilities of learners.Item Investigating the take-up of open educational resources for maths teacher education : a case study in six higher education sites in South Africa.(2011-04-12) Sapire, Ingrid M.This study has investigated the take-up, at a range of South African tertiary institutions, of Open Educational Resources (OER) designed for mathematics teacher education. Although numerous studies (e.g. Darling-Hammond, 2006; Jonassen & Rohrer-Murphy, 1999; Loughran, 2006) have identified criteria for the development of quality materials for teacher education, and have investigated ways in which these have been and should be used, little attention has been paid to the implications of these findings for the use of OER in teacher education. In 2006 the South African Institute of Distance Education (SAIDE) initiated the ACEMaths project to pilot a collaborative materials design and adaptation process in response to a Department of Education call for large scale teacher upgrading programmes leading to an Advanced Certificate in Education (ACE) in priority areas. Nine South African tertiary institutions formed the collaborative group for the development of Mathematics teacher education materials. Six of these institutions committed to using the pilot materials in their teacher education programmes in 2007. Methodologically, the research is a case study of cases (Adler & Reed, 2002), in which the varying uses of the materials in these six institutional sites constituted the individual cases. At each site data were gathered from session observations, questionnaires and interviews. Artefacts, such as examples of customised materials, were also collected. Cross case analysis revealed that institutions used the ACEMaths materials in both similar and different ways and in a range of programmes. Findings from this analysis and their implications for both initial inter-institutional designing and subsequent intra-institutional re-designing and re-use of OER are discussed.Item MBA students' experiences of academic writing : a case study.(2010-08-30) De Coning, Deborah JeanThis study explores MBA students’ experiences of academic writing, and endeavours to determine the difficulties experienced by MBA students during the writing of their dissertations especially in terms of academic literacy. Case study research design and mixed methods were used to generate both quantitative and qualitative data in this qualitative study. A constant comparative method of analysis was used to identify categories and themes within the data. The results of this research showed that the majority of MBA students, while at Business School X, viewed their identities primarily as business professionals as opposed to students of business in an academic setting. Findings of the study showed that MBA students’ identities as readers and writers are strongly framed by the business genres they encounter in their professional capacities. The study also revealed that MBA students writing their dissertations desire to produce a professionally relevant research document as much as one that meets the requirements of academic rigour. It is within this arena of academic research writing that a dilemma exists for MBA students with reference to the purpose, format and value of the dissertation as a vehicle for reporting research findings. Recommendations are that academic literacies and genre pedagogy are mainstreamed into the course design of the MBA programme at Business School X and that the repurposing of the dissertation as a genre be evaluated in terms of business relevance.
