- Description: This research project begins by exploring the problems surrounding the implementation of the 1997 Language in Education Policy (LiEP), and offers insight into why some schools, despite the promotion of additive bilingualism, choose English as the primary medium of instruction. It is a comparative case study of two Grade 1 classes in different situational contexts, which highlights the teaching strategies and language practices of teachers who teach predominantly non-English speakers through the medium of English. Research carried out through this case study illustrates the use of a wide range of teaching strategies, which assist young learners when learning through an additional language. In School A, thematic linking between different learning areas to maximise vocabulary development in both the mother tongue and the additional language, as well as repetition, recycling, scaffolding and contextualisation of content were found to be important. In addition, the use of questioning to elicit understanding, as well as classroom organisation and code-switching were strategies which assisted both the teacher and learners in this multilingual environment. In School B, class size, group work and the inclusion into the timetable of a wide range of diverse activities over and above the main learning areas, which provided opportunities for language development, were important considerations. In addition, routine, predictability and an attention to detail, in keeping with a form-focussed approach, aided the children in understanding the mechanics of literacy and guiding them towards becoming phonologically aware.

- Description: This study set out to examine whether the Eastern Cape Tourism Board (ECTB) had the capability to cope with change. The tourism industry is very dynamic and for the organization to survive, it must be able to adapt itself in a constantly changing environment. The research question was derived from a study done by Human and Horwitz (1992), in which they examined how South African companies cope with change. They developed a model and a questionnaire to measure the capabilities of coping with change. Their model and questionnaire were based on the following four dimensions: strategic orientation, control orientation, social focus and institutional focus. This model classified organizations into four types, namely: the Boardroom organization, the Technocracy organization, the Hardhat organization as well as the Missionary organization. These typologies are discussed in Chapter 2. A modified version of the Human and Horwitz questionnaire was used to conduct this research. The original questionnaire has 32 items, and the questionnaire used in this study has the same number of items. The modification was done to nine questions, to ensure that they were of specific relevance to the organization being researched. The questions were slightly modified taking care to ensure that they still fit within the original dimensions measured by Human and Horwitz (1992). The questionnaires were distributed within the organization, particularly to those employees in the Tourism section, as the organization also had a Conservation section. The Conservation section was excluded due to the fact that a policy decision had already been taken to separate the two sections, thereby creating two organizations. When the questionnaires were returned, they were analyzed using 'Statistica' , a computerized statistics program. The results showed that the ECTB does not have the capability to cope with change as it lacked the critical strategic orientation that Human and Horwitz (1992) suggest is a key requirement for coping. The profile of the organization showed that the ECTB could be classified as primarily being a Technocracy organization, and secondarily a 'Hardhat' organization. (See details in Chapter 4). Human and Horwitz (1992) suggest that an organization to be able to cope with change, must be a 'hybrid' of these four types. The implications of these results suggest that the organization is lacking in the dynamism brought about by having a strategic orientation. Human and Horwitz argue that the profile of an organization coping well with change should show a 'balance' in terms of orientation (strategic orientation and control orientation). The ECTB's profile does not show this balance, and can therefore be said not to have the capability to cope with change. The results of the profile are discussed in Chapter 4.

- Description: Against the backdrop of the growing problem of AIDS orphans in South Africa and greater sub-Saharan Africa, this qualitative enquiry examines the lives of three South African orphaned children living with HIV / AIDS in a children's home in Cape Town. It aims to generate rich, child-centred descriptions of some of the significant experiences of the children's lives. Drawings, dialogue and narrative were employed to generate the primary data. This was supplemented by collateral interviews and other relevant records, e.g. medical and biographical. Existential-phenomenological theory informed the approach to data collection and analysis. Each child produced a series often to twelve impromptu drawings over a period often weeks. These drawings and transcripts of the children's verbal descriptions of their drawings were extensively analysed. Significant themes for each participant as well as themes common to all three were identified. Some of the central themes emerging include loss, abandonment, death, disease awareness and coping. The children's ability to develop adaptive coping mechanisms and resilience in the face of traumatic loss and terminal illness was a particularly outstanding feature of the findings. Recommendations are made regarding future research to address the lack of qualitative, child-focused investigations as well as appropriate interventions for addressing the psychosocial needs of orphaned children living with HIV/AIDS.

- Description: The de-industrialisation process that was a common feature of North America and Western Europe in the 1970s, through into the 1980s has become an observable feature in African countries and South Africa in particular in the last two decades. Globally, hard hit areas include those associated with the early Industrial Revolution characterised by mass production and the agglomeration of iron and steel, coal and textile industries. General changes in the global market, especially the falling demand for extractive heavy minerals like coal and gold have also affected many countries region and localities. In the case of South Mrica, the previous high economic dependence on mined minerals like coal and gold has resulted in many once prosperous mining regions of the country being reduced to a shadow of their former selves. The worst affected areas in South Africa are those of the Klerksdorp Goldfields in the North West Province and Free State Goldfields, with the latter alone losing 100,000 jobs during the 1990s. This trend has also been acute in the coal-mining industry of the KwaZulu-Natal province since the late 1970s. The firms that had grown in the shadow of the major mining company supplyipg machinery, or who processed the semi-manufactured product are also severely affected by the closing down and restructuring in the mining and iron industries. These industries have often been forced to close down because of a break in the vital connections they developed with these mining industries. Such localised economic crisis has encouraged the universal trend towards the devolution of developmental responsibilities to the local governments and other local stakeholders to - empower them to respond to these changes. This study investigated the local economic initiatives which have been undertaken in the three municipalities of north-western KwaZulu Natal i.e. Utrecht, Dundee and Dannhauser to respond to the closures which have taken place in the mining industry of this region, which used to be among the most prosperous coal mining regions of South Africa. Using their new developmental mandate the local governments, in partnership with the communities and other external interveners have tried to respond to these localised economic crisis and also indirectly to the general poverty and underdevelopment, which characterises this region of KwaZulu-Natal. The effects of apartheid policies, and previous discriminatory rural development policies in, particular, and the Regional Industrial Development policy, which was intensively applied in the 1980s by the pre-1994 government regime, have further compounded the magnitude of the challenge. The lack of capacity in some municipalities has constrained successful implementation of Local Economic Development has led to some communities acting alone to face their situation with or without external intervention.

- Description: The hydrolysis of complex organic heteropolymers contained in municipal wastewater to simpler monomers by extracellular hydrolytic enzymes is generally considered the rate-limiting step of the biodegradation process. Previous studies of the Recycling Sludge Bed Reactor (RSBR) revealed that the hydrolysis of complex particulate organics, such as those contained in primary sludge (PS), was enhanced under anaerobic biosulphidogenic conditions. Although the mechanism was not fully understood, it appeared to involve the interaction of sulfide and sludge flocs. The current study was conducted using a 3500 ml laboratory-scale RSBR fed sieved PS at a loading rate of 0.5 kg COD/m³.day and an initial chemical oxygen demand (COD) to sulfate ratio (COD:SO₄) of 1:1. There was no significant accumulation of undigested sludge in the reactor over the 60-day experimental period and the quantity of SO₄ reduced indicated that the yield of soluble products from PS was at least as high as those reported previously for this system (> 50%). In the current study, the specific activities of a range of extracellular hydrolytic enzymes (L-alanine aminopeptidase, L-leucine aminopeptidase, arylsulphatase, α-glucosidase, β- glucosidase, protease and lipase) were monitored in a sulfide gradient within a biosulphidogenic RSBR. Data obtained indicated that the specific enzymatic activities increased with the depth of the RSBR and also correlated with a number of the physicochemical parameters including sulfide, alkalinity and sulfate. The activities of α- glucosidase and β-glucosidase were higher than that of the other enzymes studied. Lipase activity was relatively low and studies conducted on the enzyme-enzyme interaction using specific enzyme inhibitors indicated that lipases were probably being digested by the proteases. Further studies to determine the impact of sulfide on the enzymes, showed an increase in the enzyme activity with increasing sulfide concentration. Possible direct affects were investigated by looking for changes in the Michaelis constant (Km) and the maximal velocity (Vmax) of the crude enzymes with varying sulfide concentrations (250, 400 and 500 mg/l) using natural and synthetic substrates. The results showed no significant difference in both the Km and the Vmax for any of the hydrolytic enzymes except for the protease. The latter showed a statistically significant increase in the Km with increasing sulfide concentration. Although this indicated a direct interaction, this difference was not large enough to be of biochemical significance and was consequently not solely responsible for the enhanced hydrolysis observed in the RSBR. Investigation into the floc characteristics indicated that the biosulphidogenic RSBR flocs were generally small in size and became more dendritic with the depth of the RSBR. Based on the above data, the previously proposed descriptive models of enhanced hydrolysis of particulate organic matter in a biosulphidogenic RSBR has been revised. It is thought that the effect of sulfide on the hydrolysis step is primarily indirect and that the reduction in floc size and alteration of the floc shape to a more dendritic form is central to the success of the process.

- Description: This study was carried out to investigate the strategies used by teachers to foster environmental learning in the Namibian Life Science curriculum in four schools in Swakopmund, Erongo Education Region. This study is a qualitative case study. I used semi-structured interviews, observation and document analysis as instruments to collect data. Two schools were selected to participate in the case study. Research participants included four teachers (two teachers from each school) of which two teachers are teaching at each school. The study was contextualised through a review of policy changes in Namibian education, which focus on learner-centred education. The study identified six strategies used by teachers to foster environmental learning in the Life Sciences curriculum. These are planning; working with information; practical, excursions and clubs; involving the learners; using visual aids and teaching materials; and choosing topics with a local focus. Through a consideration of the different strategies used by teachers, in relation to the learner-centred nature of the educational reform project in Namibia the study provides insight into the way in which teachers view learner-centred education. The study also illuminates how strategies used by teachers reflect learner-centred education principles and it outlines a number of tensions emerging in the fostering of environmental learning in learner-centred ways. The study identifies further support required by teachers, and makes recommendations which will further enhance the strategies used by teachers to foster the environmental learning focus in Life Sciences, and also enhance learner-centred teaching in Life Science.

- Description: Biotechnology of sulphate reducing bacteria has developed rapidly in recent years with the recognition of their extensive and diverse biocatalytic potential. However, their application in a number of areas has been constrained due to problems including poor cell retention within the continuous bioprocess reactor environment, and contamination of the treated stream with residual organic feed components and cell biomass. These problems have so far excluded the application of biological sulphate reduction in the treatment of ‘clean’ inorganic waste streams where components such as sulphate, acidity and heavy metal contamination require treatment. This study investigated the effective immobilisation of sulphate reducing bacterial cultures and proposed that the disarticulation of the electron donor and carbon source supply using such systems would create the basis for their application in the treatment of ‘clean’ inorganic waste streams. A functional and stable sulphate reducing culture was selected and following evaluation using a number of techniques, was immobilised by encapsulation within a calcium-alginate-xanthum gum membrane to give robust capsules with good sulphate reduction activity. The concept of disarticulation was investigated in a swing-back cycle where the carbon source was excluded and the electron donor supplied in the form of hydrogen gas in a continuous up-flow capsule-packed column reactor. Following a period of operation in this mode (4-12 days), the system was swung back to a carbon feed to supply requirements of cell maintenance (2-3 days). Three types of synthetic ‘clean’ inorganic waste stream treatments were investigated, including sulphate removal, neutralisation of acidity and heavy metal (copper and lead) removal. The results showed: • Sulphate removal at a rate of 50 mg SO₄²⁻L/day/g initial wet mass of capsules during three 4-day cycles of electron donor phase. This was comparable to the performance of free cell systems; • Neutralisation of acidity where influent pH values of 2.4 and 4.0 were elevated to above pH 7.5; • Copper removal of 99 and 85 % was achieved with initial copper concentrations of 2 and 60 mg/L respectively; • Percentage lead removal values of 49 and 78 % were achieved; This first report on the application of the concept of capsular immobilisation and disarticulation in the treatment of ‘clean’ inorganic waste streams will require future studies in order to extend the development of the full potential of the concept.

- Description: Biotechnology of sulphate reducing bacteria has developed rapidly in recent years with the recognition of their extensive and diverse biocatalytic potential. However, their application in a number of areas has been constrained due to problems including poor cell retention within the continuous bioprocess reactor environment, and contamination of the treated stream with residual organic feed components and cell biomass. These problems have so far excluded the application of biological sulphate reduction in the treatment of ‘clean’ inorganic waste streams where components such as sulphate, acidity and heavy metal contamination require treatment. This study investigated the effective immobilisation of sulphate reducing bacterial cultures and proposed that the disarticulation of the electron donor and carbon source supply using such systems would create the basis for their application in the treatment of ‘clean’ inorganic waste streams. A functional and stable sulphate reducing culture was selected and following evaluation using a number of techniques, was immobilised by encapsulation within a calcium-alginate-xanthum gum membrane to give robust capsules with good sulphate reduction activity.

- Description: This study investigated relationships between marketing success, the level of external environmental complexity and turbulence, and marketing mix tactics. The literature suggested that more successful companies in simple and stable environments use stabilising marketing tactics, while more successful companies in complex and turbulent environments use destabilising tactics, regardless of industry habits, management preferences or market sector. A marketing mix model for the different environments was developed using a chaos and complexity theory perspective. The study was exploratory, using a qualitative, case study technique. Data was collected via depth interviews and document analysis from four companies in the information technology (IT) and packaging industries. These industries were identified as, respectively, the most complex and turbulent, and the simplest and most stable, South African environments. Two companies from each industry were chosen to reflect more successful and less successful companies. The more successful company in the complex/turbulent environment was found to use destabilising tactics, as did the more successful company in the simple/stable environment. Therefore, contrary to expectations, it appears that destabilising tactics contribute more to success than stabilising tactics do, regardless of the environment. It was also found, contrary to expectations, that stabilising tactics were used by both the less successful companies. The research concluded that destabilising tactics are related to more success and stabilising tactics to less success. The lack of clear differentiation between the two industries may be because the whole South African environment is complex and turbulent, because the packaging industry is not sufficiently simple and stable to differentiate it from the IT industry or because packaging industry managers perceive their industry to be complex and turbulent and act accordingly. Despite these uncertainties, the research showed the marketing mix model to be reasonably accurate for the complex/turbulent environment, and therefore of potential value to South African companies. To overcome the equivocal findings, further research is recommended in different industries, in countries with different levels of complexity and turbulence and into specific marketing mix tactics. Research into managers’ perceptions of environmental complexity and turbulence and into co-evolution of marketing tactics and external environments would also be of value.

- Description: Maternal HIV-infection is considered to be a threat to the psychosocial development of AIDS-affected children. In South Africa, AIDS-affected children may be particularly vulnerable due to the unprecedented effects of the HIV/AIDS epidemic on the breakdown of family and community resources in already disadvantaged communities. The aim of this study was to explore the contextualised experiences of two children living with mothers who have HIV by conducting two case studies. Mother-child dyads were recruited from local HIV/AIDS centres and informed consent was obtained. The mothers were in the minor symptomatic phase of HIV-infection and the children were uninfected and aged between 10 and 12 years. Through semi-structured interviewing, the mothers provided background and contextual information about the children. Play techniques were used in the child interviews to encourage the introduction and exploration of issues salient to the children. Play facilitated engagement around sensitive and potentially anxiety-provoking material. A key issue for the children was their concerns about the anticipated deaths of their mothers. The children held misconceptions about the transmission of HIV/ AIDS. They feared HIV/AIDS and expected that others would have negative perceptions of them. Family processes such as secrecy and avoidance around HIV/AIDS-related issues were understood to perpetuate the children's fears and false beliefs in a broader community context that stigmatised HIV/AIDS. It was argued that the mothers' shame over HIV-infection and their need to protect their relationship with their children compromised their ability to communicate openly with their children and to offer them meaningful emotional support. Limited parental involvement was identified as the key contextual process that engendered vulnerability in the children, as they were isolated within and beyond the family. Recommendations to address the processes that engendered vulnerability in the children are discussed.

- Description: The purpose of this research was to investigate three principals’ perceptions and experience of participative management and to gain insight into and understanding of the dimensions involved in participative management from the perspective of the three principals. The research was conducted within the interpretive paradigm, since I was interested in understanding the subjective experience and individual perceptions of three principals with regard to participative management and the meaning they attach to it in their natural settings: how they describe, interpret and make sense of participative management. Data were collected by means of questionnaires, interviews and observation. The findings indicate overwhelming support for the notion that participative management (collegiality) does have a positive influence with regard to creating a sense of common goals, shared vision, a sense of ownership, commitment and improved human relations. The respondents emphasized the critical role of the leader in facilitating the implementation of collegiality as well as an increasing awareness of the potential of participative management to improve human development through delegation. The responses revealed interesting paradoxes with regard to the tensions between leadership and leaderless organizations, as well as between autonomy and interdependence. Responses also reflect the sentiment that participative management should be selective, involving only those with the necessary skills and expertise in the decision-making process. While there is an appreciation of the benefits to be derived from collegiality, critical statements about participative management include the time-consuming nature of participative management, and the notion that participative management impinges on the authority of the principals.

- Description: The censorship of popular music in South Africa during the 1980s severely affected South African musicians. The apartheid government was directly involved in centralized state censorship by means of the Directorate of Publications, while the South African Broadcasting Corporation exercised government censorship at the level of airplay. Others who assisted state censorship included religious and cultural interest groups. State censorship in turn put pressure on record companies, musicians and others to practice self-censorship. Many musicians who overtly sang about taboo topics or who used controversial language subsequently experienced censorship in different forms, including police harassment. Musicians were also subject to anti-apartheid forms of censorship,such as the United Nations endorsed cultural boycott. Not all instances of censorship were overtly political, but they were always framed by, and took place within, a repressive legal-political system. This thesis found that despite the state's attempt to maintain its hegemony, musicians sought ways of overcoming censorship practices. It is argued that the ensuing struggle cannot be conceived of in simple binary terms. The works of Antonio Gramsci, Michel Foucault and Pierre Bourdieu, in particular, are applied to the South African context in exploring the localized nuances of the cultural struggle over music censorship. It is argued that fragmented resistance to censorship arose out of the very censorship structures that attempted to silence musicians. Textual analysis brought to light that resistance took various forms including songs with provocative lyrics and titles, and more subtle means of bypassing censorship, including the use of symbolism, camouflaged lyrics, satire and crossover performance. Musicians were faced with the challenge of bypassing censors yet nevertheless conveying their message to an audience. The most successful cases negotiated censorial practices while getting an apparent message across to a wide audience. Broader forms of resistance were also explored, including opposition through live performance, counter-hegemonic information on record covers, resistance from exile, alignment with political organizations and legal challenges to state censorship. In addition, some record companies developed strategies of resistance to censorship. The many innovative practices outlined in this thesis demonstrate that even in the context of constraint, resistance is possible. Despite censorship, South African musicians were able to express themselves through approaching their music in an innovative way.

- Description: This research was conducted in Luwero, a rural district in central Uganda, over a period of three years, half of which entailed fulltime engagement in a participatory action research process with VEDCO, an indigenous NGO. The study focuses on the educational processes involved in the translation of Uganda's environmental policy into action at community level. It looks at community-based education and development activities run by VEDCO among smallholder farmers. The study addressed four objectives. For the first objective I developed a conceptual framework through a review of theories informing education in general and environmental education, adult education, community education, and community development in particular. The second objective was to conduct a situational analysis to identify contextual issues related to policy implementation at community level. The third objective was to engage in a participatory action research process with the NGO in the farming community in response to the identified contextual issues, and the fourth was to explore and comment on environmental education methods used within a community context. PRA techniques, interviews, and other participatory data collection methods were used to generate the data. The study reveals contradictions that limit NGO capacity to make appropriate use of participatory education processes in implementing policy-related training at community level. Elements in the National Plan for the Modernisation of Agriculture, for example, conflicted with the principle of sustainable development underlying the policy. VEDCO itself was changing from a social-welfare-oriented organisation into a commercial enterprise pursuing economic goals, which conflicted with its social goals. The capitalist development ideology of the donor was being adopted by VEDCO, which contradicted the goals of people-centred development. This was exacerbated by VEDCO's dependency on donor funds for its activities. Contextual issues like people's history; poverty, gender and inconsistent land policies further complicated the policy implementation processes. There were also inconsistencies in the epistemological assumptions and didactic approaches evident in the implementation. The study shows that the intended emancipatory education processes are more often supplanted by technicist methodologies. Thus, it exposes the underlying historical, ideological and epistemological tensions and contradictions within the field of education, particularly in relation to the `paradigmatic' orientations (neo-classical, liberal and socially critical/emancipatory) outlined in the literature. Conclusions are made at two levels: in relation to the study goals, of examining policy implementation at community level and in terms of the study's contribution to the understanding of current education theory in the context of sustainable development among communities.

- Description: The research presented in this thesis is situated within an interpretivist paradigm. Within this paradigm, a qualitative case-study research approach was adopted. This seemed most appropriate in my research project since the main focus is on elicitation of prior knowledge and incorporation of such knowledge into 'hands-on' and 'minds-on' practical activities with a view to improving conceptual development. For the purposes of this research project, I designed an interactive teaching and learning unit in electrostatics as an attempt to put into practice a learner-centred approach. This approach, in my view, is in line with the new curriculum in South Africa. The emerging central theme of this thesis is the notion of active participation by learners during teaching and learning. This study was carried out over a period of two years and involved my grade 9 learners, who participated voluntarily. The research process documented in this thesis has been conceptualised into two phases. Phase one was concerned with the elicitation of learners' prior knowledge around lightning. In phase two, learners were engaged in 'hands-on' and 'minds-on' practical activities, and key concepts were identified to ensure conceptual development. The data was collected using a variety of data collection tools, namely: focus group interviews, follow-up whole-class semi-structured interviews, worksheets, videotaped lessons and photographs. The analysis of data revealed that learners come to class with prior knowledge concerning lightning. Within this prior knowledge it was found that there were both ‘scientific’ and ‘non-scientific’ concepts. The identification of key concepts during practical activities was found to be very useful in promoting learning. However, the incorporation of prior knowledge into practical activities posed a challenge and needs further research. iv This research study also highlights some insights into some of the complexities of elicitation and incorporation of learners' prior knowledge, and conceptual development in science classrooms. It also demonstrates the challenges and possibilities during teaching and learning as well as the realities of the demands of the new curriculum and OBE in South Africa, in particular, in historically disadvantaged schools

In phase two, learners were engaged in 'hands-on' and 'minds-on' practical activities, and key concepts were identified to ensure conceptual development. The data was collected using a variety of data collection tools, namely: focus group interviews, follow-up whole-class semi-structured interviews, worksheets, videotaped lessons and photographs. The analysis of data revealed that learners come to class with prior knowledge concerning lightning. Within this prior knowledge it was found that there were both ‘scientific’ and ‘non-scientific’ concepts. The identification of key concepts during practical activities was found to be very useful in promoting learning. However, the incorporation of prior knowledge into practical activities posed a challenge and needs further research. iv This research study also highlights some insights into some of the complexities of elicitation and incorporation of learners' prior knowledge, and conceptual development in science classrooms. It also demonstrates the challenges and possibilities during teaching and learning as well as the realities of the demands of the new curriculum and OBE in South Africa, in particular, in historically disadvantaged schools

- Description: Paper 1. The purpose of this analysis is to critically evaluate the Lower Primary Mathematics programme within the context of the Namibian educational reform, against the backdrop of learner-centred education from within the Constructivist epistemology. Through the analysis of a small-scale survey, I will try to determine the extent to which learners, teachers and other educationalists, involved in the Lower Primary school phase, understand the new approach to Mathematics and their pedagogical and theoretical insight into the new programme. I will also analyse the syllabus documents in view of the educational policies and further discuss the social, historical and economic background to the reform. I will then analyse the progress or development of the reform process through discussing the learning environment as well as the learners who are the central participants in education. Paper 2.This critical discussion aims to explore the prospects and underlying principles of the epistemologies of two opposing paradigms of education: Behaviourism and Constructivism. I have critically examined and compared the theoretical aspects that shape and inform the model of instruction and the systemic implications of the learning process. The purpose was to compare both learning theories and to draw a conclusion of which the better epistemology is for the teaching and learning process. Paper 3. This is an investigation into the theories that underpin and inform mathematics teaching in the Lower Primary phase of the primary school in Namibia. The Namibian society requires the development of knowledge and understanding, skills and competencies, attitudes and values, which everyone must have to be able to function adequately in society on a social, economic and political level (MBESC 1996). We need to seek ways of enhancing mathematics teaching in Namibia if we want to live up to the expectations of our society. Paper 4. Mathematicians and researchers across the globe have theorised and speculated about education reform movements, which aim for more than just structural knowledge where it concerns Mathematics. This action research study is based on the findings of a pilot study about 'Problem-based Learning', using this as a basis to investigate the relationship between the intentions of the Lower Primary Mathematics curriculum and its implementation at classroom level. This paper reports on a case study of two grade one teachers' perceptions of problem solving as a key component of Mathematics learning and how the implementation of the problem-based approach could be supported through intervention. Data was gathered from a series of cycles of planning, acting, observing and reflecting. Analysis of the data indicates that teachers' professional development lies within a willingness to change and in reflexive practice. Given focused support to teachers could result in the application of contemporary approaches to Mathematics teaching, with an overall improvement of constructivist-oriented learner-centred education.

- Description: Miscarriage can result in significant psychological distress to women. However, many women experience a cultural norm which attributes minimal meaning to the loss. This is reflected in the lack of support experienced from interaction with both medical professionals and those within the individual's social context. This qualitative study reports on the unique experiences of six South African women; their experience of other's reactions to their miscarriage; and their recommendations for better coping with the experience. Data was gathered using one semi-structured interview. Data reduction and analysis followed using a four-stage model of thematic outlines, coding, and comparisons (Marshall and Rossman 1998:152; Marck and Field 1994:9). The objective of the analysis sought to compare the themes generated by the actual data collected with those described in other studies. In this way the findings of the study are generalisable to a larger population and allows for a greater sense of representivity (Silverman 1994:160). Comparisons were made between the women's experiences, as told by them, and Bowles' identification of the Four Domains of Miscarriage Distress Symptoms (2000). The women viewed psychological support as essential in the process of coping; and acknowledgement of their loss as being the loss of a child, as a strong determinant of coming to terms with the loss. A strong need to have support from other women who had shared the experience was voiced. Recommendations for improved intervention are made. In short the core recommendations are: the provision of patient follow-up; the provision of written material; and, specialist training for those working in the area of pregnancy loss.

An exploration of how professional graphic design discourse impacts on innovation : a focus on the articulation of a South African design language in i-jusi

- Description: This study examines the graphic design industry’s call for ‘a South African design language’ in post-apartheid South Africa and how the non-commercial publication i-jusi is envisaged as a space for graphic designers to innovate a South African design language. The central premise of this research is that graphic design, as a form of cultural production, is discursive. In this respect, graphic design practice is constructed and constrained by professional discourse, which is in turn informed by social structures. However, discourse is also a site of contestation and graphic designers may challenge or negotiate professional discourse in their practice. Thus, as Wolff (1981) argues, the possibility for innovation within graphic design practice may exist at a particular historical moment, although this possibility is itself situated within social structures. In this study, the impact of professional graphic design discourse on the attempt to innovate a South African design language in i-jusi is explored. Utilising qualitative interviews and other texts selected from graphic design commentary (conference presentations and published articles), the motivations of the producers of i-jusi are examined with a view to assessing how their articulation of a South African design language is informed by professional graphic design discourse.

- Description: Cognisant of the fact that counselling has become an essential aspect of dealing with HIV/AIDS in South Africa, the researcher aimed to explore the stressors experienced by HIV/AIDS counsellors. It was envisioned that the results obtained would both help to improve the counselling services provided at Settlers Hospital, and assist other organisations to do so. The research focused on how the participants dealt with the dual roles of non-directive listening and the more prescriptive advice-giving, the stressors they experienced and the support structures they had, or needed, to assist them in being more effective HIV/AIDS counsellors. The sample consisted of four HIV/AIDS counsellors working at Settlers Hospital, Grahamstown. The co-ordinator of HIV/AIDS at the hospital was interviewed for collateral information. A qualitative, multiple case study was undertaken. In-depth, semi-structured interviews were used to collect the data which were recorded and transcribed and then constructed into coherently organised personal narratives of each participant’s experiences. A composite description of all the results was arrived at through the use of a reading guide which reduced the data into a thematic content analysis. The analysed data served to present an understanding of the counsellors’ experiences and to enable recommendations to be made which could assist them in pursuing their work more effectively. The findings of this study indicate that HIV/AIDS counselling is an emotionally stressful occupation. Contributory factors include the twofold role of promoting prevention and serving as empathic listeners. Other stressors derive from issues of confidentiality and stigma concerning HIV/AIDS, counsellors’ identification with clients’ experiences and the demographics of HIV/AIDS in South Africa. Situational stressors which arise from working as both nurses and counsellors in a public health institution were also identified. Recommendations are made to alleviate the counsellors’ stress in the form of facilitated emotional support groups, professional supervision, managerial support to improve the working environment, and ongoing in-service training.

The implementation of multigrade teaching in rural schools in the Keetmanshoop education region: leadership and management challenges

- Description: Leadership has received much attention in both the business world and education. My thesis explores effective educational leadership through examining the management and leadership challenges that face principals in a multi-grade school. Schools in sparsely populated rural areas in Namibia have had to resort to multi-grade teaching to be able to be economically viable. Hard economic realities force people to move to bigger towns and cities. The constant demand for better schools, effective principals, qualified teachers and an improved service to the communities coupled with the demand for better working conditions and salaries for teachers drained the education budget even further. To keep in line with the four major policies of education namely equity, access, quality and democracy, the operation of smaller, rural multi-grade schools has become a necessity. The alternative – which is to close smaller schools and operate fewer, bigger schools at an affordable and reasonable cost - would deny rural communities access to schooling. This thesis is a case study of the leadership and management challenges of multigrade schooling in a single school. The goal was to understand how education managers and leaders perceived their role in making it possible for teachers and learners to cope with multi-grade teaching. I worked in the interpretive paradigm to be able to interpret the social and cultural context of a rural, multi-grade school in the Karas region. The methods included questionnaires, interviews and observation. One of the leadership models universally considered to be available to principals of multi-grade schools is instructional leadership. My study revealed that the concept was unknown to teaching staff, although there were indications that the model had been encountered. My findings also revealed that the communication between colleges of education and the regional education department staff was very limited. One of the major issues that arose was that principals were so occupied with teaching that important issues about training/evaluation and supervision of teachers, the ‘visibility’ of the principal, setting and implementation of the aims and goals of the school and regular communication with parents and community leaders were neglected. Probably the most significant finding was that head teachers are not trained in the management of a multi-grade school, hence most if not all of the head teachers run multi-grade schools like a single-graded school. The single most important problem was that the importance of multi-grade teaching had never been highlighted, particularly in light of new staffing norms, in spite of the fact that it was a phenomenon that was likely to be a permanent arrangement.
