Magister Artium - MA / There is global interest in teacher education as a strategy for national development. More specifically, emphasis is placed on teachers as the driving force behind educational provision which is central to achieving high standards of learner achievement. This study focused on teacher in-service development and its role for effective teaching and learning towards the holistic development of learners. Extensive social inequalities, along the lines of race, still exist in South Africa almost twenty years into the new dispensation. This is evident by the vast majority of impoverished schools in previously disadvantaged areas. Learners at these schools experience a range of barriers to learning which impede teaching and learning. Consequently, teachers at these schools are confronted with a tensionfilled task: having to be sensitive to the needs of these learners, whilst at the same having to ensure their success. This is reflected in Department of Education (DoE) policies which emphasises principles of social transformation for redress and equity, coupled with the acquisition and application of knowledge and skills for the benefit of individuals in South Africa, as well as global trends. As a quantitative data collection method in this mixed method study, 55 teachers (of which 26 responded) from two schools, were asked to complete a questionnaire on the effectiveness of teacher in-service development programmes towards the holistic development of learners. Qualitative data collection methods entailed interviewing a principal of one of the schools; a social worker from the area; as well as a district officer from the Western Cape Education Department (WCED). In addition, relevant DoE policies were reviewed. Findings reflect that teachers at impoverished schools are confronted with a range of challenges presented by learners in the classrooms. The findings also indicate that even though DoE policies reflect a commitment to teacher development, the in-service programmes offered to teachers mostly do not reflect the needs of teachers for the holistic development of learners. In instances where inservice programmes do assist with the holistic development of learners, findings indicate that the implementation thereof is challenging due to the high teacher: learner ratio and limited resources. Thus, recommendations include the periodic monitoring and review of long-term DoE teacher development initiatives whilst short term measures incorporate giving attention to impediments like lack of parental support and behavioural challenge. Long term measures, which are strongly recommended, encompass systemic change that facilitates the working together of a number of governmental departments. In so doing, educational reform takes on a society wide form, as it is evident that on its own it cannot abate poverty and the related effects. Thus, the DoE’s vision of education for social transformation towards redress and equity, as well as economic growth for individuals and South Africa is more plausible. These recommendations create a vital space for future research.

Philosophiae Doctor - PhD / This research study examines those aspects of Indigenous Knowledge (IK) that could be socially and culturally relevant in the Western Cape Province, South Africa, for teaching meteorological science concepts in a grade 9 Social Science (Geography) classroom using dialogical argumentation as an instructional model (DAIM). The literature reviewed in this study explains the use of argumentation as an instructional method of classroom teaching in particular dialogical argumentation, combined with IKS (Indigenous Knowledge Systems), which in this study is seen as a powerful tool both in enhancing learners’ views and positively identifying indigenous knowledge systems within their own cultures and communities, and as tool that facilitates the learning of (meteorological) literacy and science concepts. With the development of the New Curriculum Statements (NCS) and the Curriculum and Assessment Policy Statements (CAPS) for schools, the Department of Basic Education (DBE) of South Africa acknowledges a strong drive towards recognising and affirming the critical role of IK, especially with respect to science and technology education. The policy suggests that the Department of Education take steps to begin the phased integration of IK into curricula and relevant accreditation frameworks. Using a quasi-experimental research design model, the study employed both quantitative and qualitative methods (mixed-methods) to collect data in two public secondary schools in Cape Town, in the Western Cape Province, South Africa. A survey questionnaire on attitudes towards, and perceptions of high school, of a group of grade 9 learners, as well as their conceptions of weather, was administered before the main study to give the researcher baseline information and to develop pilot instruments to use in the main study. An experimental group (E-group) of learners were exposed to an intervention - the results were recorded against a control group (C-group) that were exposed to no intervention. Both the E-group and C-group were exposed to a Meteorological Literacy Test (MLT) evaluation before and after the DAIM intervention. The results from the two groups were then compared and analysed according to the two theoretical frameworks underpinning the study, namely, Toulmin’s Argumentation Pattern - TAP (Toulmin, 1958) and Contiguity Argumentation Theory - CAT (Ogunniyi, 1997). The findings of this study revealed that: Firstly, the socio-cultural background of learners has an influence on their conceptions of weather prediction and there was a significant difference between boy’s and girls’ pre-test conceptions about the existence of indigenous knowledge systems within the community they live in. For instance, from the learners’ excerpts, it emerged that the girls presented predominantly rural experiences as opposed to those of the boys which were predominantly from urban settings. Secondly, those E-group learners exposed to the DAIM intervention shifted from being predominantly equipollent to the school science to emergent stances and they found a way of connecting their IK to the school science. The DAIM model which allowed argumentation to occur amongst learners seemed to have enhanced their understanding of the relevance of IK and how its underlying scientific claims relate to that of school science. Thirdly, the argumentation-based instructional model was found to be effective to a certain extent in equipping the in-service teachers with the necessary argumentation skills that could enable them to take part in a meaningful discourse. The study drew on the personal experiences and encounters from a variety of sources. These included storytelling-and sharing, academic talks with local community members recorded during the research journey, formal round table discussion and talks at international and local conferences, conference presentations, informal interviews, indigenous chats at social event-meetings, and shared experiences at IKS training workshops as a facilitator. These encounters lead to the formulation of the research study and occurred throughout the country in various parts of the Southern African continent including: Namibia, Zimbabwe, Malawi, Botswana, Tanzania and Mozambique.
