- Description: This study investigates organisational culture and shared values that currently exist at Saint’s Bistro in Grahamstown along with the desired organisational culture and desired values. In particular it explores possible discrepancies between the two using the reliable and valid Competing Values Framework (CVF) and its matched scale, the Organisational Culture Assessment Instrument (OCAI) and the Shared Values Survey. McDonald and Gandz (1992: 64-67) discovered 24 shared values that correlate with modern business and where each value ties in with one of the four quadrants of the CVF. The researcher found a study conducted by Burchell and Saele (2011: 512) which is a cultural study based on the CVF working in conjunction with shared values survey to analyse a situation and it presented an improved means of investigating culture and values related facets within an organisation. The aim of this study is to examine the existing culture and subsequently make recommendations that can create alignment between what is currently experienced and what is desired in the organisation, if it is found that misalignment exists. This research presents a study using a paper based survey conducted in a restaurant in Grahamstown, South Africa. The results are based on the use of the OCAI in conjunction with organisational shared values profiles. The study revealed that there is no significant gap between the current organisational culture and the desired organisational culture within the organisation. Due to these findings, the research established that a structured strategy for maintaining the organisational culture should be developed in order to sustain the existing organisational culture that can be used when recruiting and on-boarding new employees in the future. The research is significant in that it highlighted a link between the competing values framework and the shared values survey and this will contribute to the effective analysis of organisational culture in future culture research.

- Description: This case study was conducted at a secondary school where I teach, situated in the semi-rural setting of Bukalo village in Namibia, and sought to gain insights into the nature and role of visualisation processes employed when selected grade 11 learners interacted with selected geometry problems. According to Mariotti and Pensci (1994), visualisation takes place when "thinking is spontaneously accompanied and supported by images”, and helps students to understand the problem at hand. Visualisation is regarded as "making the unseen visible and imagery as the power to imagine the possible and the impossible” (Mason 1992). The study is located within an interpretive research paradigm in order to obtain in-depth understanding of the participants’ visualisation processes. Within this paradigm, both quantitative and qualitative approaches were adopted. The eight Grade 11 participants engaged with 12 items of the Geometry Visualisation Tasks (GVT) worksheets. Data was collected using video-recorded learners’ interactions with the GVT, observations, stimulated recall interviews and post-GVT interviews with the learners. During the data analysis stage, I used inductive analysis to determine patterns evident in learners ‘thinking processes’. My analytical framework consisted of indicators that were used to identify and classify visualisation processes for each task of the GVT for each participant. I adapted this framework from Ho (2010) and Ho, Ramful and Lowrie’s (2015) clarification of the representations. The findings from this study revealed that the use of visualisations facilitated meaningful learning when learners made use of these to develop and scaffold their conceptual understanding. The findings revealed that most learners used visualisation processes fairly to very accurately when solving geometry problems. They used visualisation processes by using sketches and diagrams that transformed a mathematical problem pictorially, connected their thinking to previous knowledge and experience, clarified the algebraic task and assisted them to understand the spatial relationships within each task.

- Description: The study was carried out in order to analyse the effect which the requirement for integrated reporting has had on the description of strategy and strategic planning processes of three South African Banks during the three-year period between 2012 and 2014. The study was conducted in three Johannesburg Stock Exchange listed Banks namely Barclays Bank, Capitec Bank and Standard Bank and focused on their integrated reports for 2012 to 2014. The objectives of the study were to analyse the change in the scope of the depth of reporting on strategy, analyse the evolution of the strategic planning process, compare and contrast the banks’ nature, scope and depth of reporting and establish how the requirement for integrated reporting has impacted on the strategic planning processes in the banks. The study was carried out as a content analysis of the integrated reports of the three banks. The sample for the study consisted for the 9 integrated reports issued by the three banks in the period from 2012 to 2014. There was an increasing trend in the prominence of reporting on strategy by the C.E.Os and chairmen of the companies in the integrated reports. All the companies exhibited an increase in the depth of their reporting on strategy in their overall integrated reports. There is a general increase in the depth of reporting on value creation in the integrated reports. From discussing their business models to some extent in 2012 and 2013, all integrated reports reported on strategy to a large extent in 2014. The study concluded that the scope and depth of reporting on strategy was growing. The study also concluded that strategic planning processes had been transformed due to the requirement for integrated reporting. It was also concluded that Standard Bank had the greatest focus on strategy. Further studies may focus beyond strategy and explore the extent to which companies are implementing non-financial measures in their integrated reporting.

An analysis of the impact of financialization on commodity markets

- Description: An unprecedented increase in real commodity prices from 2002-2011 fuelled an intense debate as to the causes of the steep rise in prices and its possible implications for producers and consumers. On the one hand, the prolonged and dramatic rise in almost all commodity prices is attributed to growing demand from emerging market economies, supply shocks such as adverse weather conditions, export bans as well as other macroeconomic factors. Collectively these are known as the fundamental (demand and supply) factors. On the other hand, there is a growing body of evidence that suggests these fundamental factors alone are not sufficient enough to explain recent commodity price developments. It is noted that alongside changes in the fundamental factors, there was a major shift in trading activities on commodity derivative markets related to the increasing presence of financial investors, institutional investors and hedge funds. This had important effects, it is argued, on the microstructure of these markets and on price dynamics in a process termed “fmancialization”. Most of the empirical literature covers the period of rising commodity prices from 20022011. This study seeks to add to the existing literature by examining, in addition, the impact of financialization when commodity prices were falling from 2011-2015. Whereas the literature focuses mainly on the rise of agricultural commodity prices, the focus of this study is on metals, oil and bulk commodities (coal and iron ore). Two techniques are employed, namely the calculation of rolling correlations for futures and spot returns. Granger causality tests are then performed to examine the relationships between futures and spot prices. Rolling return correlations are calculated for i) different exchange- traded commodities and ii) exchange-traded commodities and bulk commodities not traded on exchanges. This is done to establish whether the increased correlations between different commodities found in the literature still hold now that commodity prices across all categories are falling. Granger causality tests are used in order to establish the link between the futures prices and spot prices both during the upswing period (2002-2011) and downswing period (2011-2015). It is found that rapidly growing indexed-based investment in commodity markets (financialization) during the upswing period is concurrent with increasingly correlated returns on the prices of unrelated commodities in both the futures and spot markets. These correlations decline during the period of falling commodity prices (2011-2015). This was a period in which the total amount of commodity assets under management fell sharply. This supports the a priori expectation that if the increased correlations of previously seemingly correlated and unrelated commodities during the upswing had been driven by financialization, the correlation would decline in the downturn. Granger causality results reveal statistically significant evidence of futures prices (returns) driving spot prices (returns) during the financialization period. However, post-financialization there is a shift to more bidirectional relationships. The study therefore concludes that, in addition to changing fundamental and macroeconomic factors, the financialization of commodity markets further drove the excessive and volatile price levels in commodity markets from 2002 to 2011.

- Description: Textbooks are a universal and central element of teaching and learning mathematics (Namibia. Ministry of Education [MoE], 2008). Steenpaß and Steinbring (2014) state that diagrams in mathematics textbooks are often used as Visualisation Objects (VOs) to enhance learning of mathematical concepts. VOs in textbooks are thus important teaching and learning tools (Fotakopoulou and Spiliotopoulou, 2008). This Namibian interpretive case study analysed the nature of VOs used in the three approved grade 9 Namibian mathematics textbooks namely: y=mx+c to success, Maths for Life 9 and Discover Mathematics 9. The VOs were analysed by using an analytical framework adapted from Fotakopoulou and Spiliotopoulou (2008). This analytic tool was specifically used to interrogate the following categories: the type of VOs, the roles of VOs, the relation of VOs to mathematical content, the relation of VOs to reality, and their properties. The 266 VOs under study were collected from the Algebra and Geometry chapters of each book. This study also included survey questionnaires with the 50 selected mathematics teachers, which sought their views and perceptions on the use of the identified VOs. In addition, the authors’ rationale in selecting the identified VOs used in their textbooks was sought through interviews. This research study is part of the “Visualisation in Namibia and Zambia” (VISNAMZA) project which seeks to research the effective use of visualisation processes in the mathematics classroom in Namibia and Zambia (Schäfer, 2015). It is hoped that this study contributes towards improving the quality of textbook evaluations, and design of suitable and more comprehensive assessment procedures in Namibia. It is also hoped that it creates a critical awareness of the roles of VOs in textbooks amongst teachers, inspiring them to help their learners interpret VOs effectively. It should also inspire potential authors to use suitable and appropriate VOs that enhance conceptual teaching and learning of mathematics. The study discovered that most of the VOs used in the selected textbooks align well with the mathematical content. The VOs can help make abstract ideas concrete, stimulate learning, simplify and clarify written texts. In addition, VOs can also be used as a tool for reasoning and an instrument for problem solving. The findings however also indicate that some of the VOs used are not self-explanatory; they are vague, unfamiliar and confusing, leading to misinterpretations by some learners. Another interesting finding was that some of the learners found it difficult to interpret VOs on their own without the help of the teacher.

- Description: Visualisation is gaining visibility in mathematics education research. It is a powerful tool for solving different types of problems in many areas of mathematics, including Algebra - the mathematical domain of this study. The aim of this case study was to analyse the visualisation processes that selected senior secondary school learners used to solve a set of ten algebraic problems.The research was conducted at a secondary school in the Erongo region of Namibia. This is the school where the researcher is teaching. The sample consisted of six selected learners, three from Grade 11 and three from Grade 12. The learners were purposefully selected to participate in this study based on their mathematics performance in class and their willingness to participate. The participants were video recorded as they worked through the ten items of an Algebraic Visualisation Tasks (AVT) worksheet. They were also interviewed about the visualisation processes they employed when solving each of the tasks. The AVT, the videos and the interviews were analysed with the aid of an adapted visualisation template. The findings of the study show that learners used visualisations in all their problem-solving processes. These visualisations were used for different purposes such as starting points, for illustrative purposes, as organizational tools and as simplification tools. Visualisations as starting points were used when the problem was wordy and had lengthy descriptions and explanations. Illustrative visualisations enabled learners to articulate in their own way mathematical notations, mathematical equations and expressions that they then used to solve the problem. Organizational pictures provided a useful structural framework for solving the problems.This research suggests that the selected participants indeed used visualisation processes to solve algebraic problems. It is thus important for teachers to harness this aid and make the most use of these visualisation processes when teaching Algebra.

- Description: This thesis focusses on the role of judges as interpreters of tax legislation. It examines the role of judges by analysing how the perceptions of judges can impact on how they interpret legislation. It also analyses various other factors that play a role when judges interpret legislation, in an effort to answer the question to what extent do philosophical theories and interpretative approaches explain the role of judges as interpreters? Jurisprudential theories such as the natural law theory, positivist theories, and American realist theories are used to analyse how judges interpret and how theorists think judges should play their interpretational role. It is noted that in pre-constitutional South Africa the courts followed a positivist paradigm; as a result, the judges used a strict literal approach to interpretation. The new Constitution brought a change in the jurisprudential paradigm accepted in South Africa and has transformed how judges perceive and carry out their role as interpreters of legislation. Judges have now adopted the purposive value-laden approach as authoritative. As custodians of the Constitution, judges should interpret provisions against the values imposed by it. The purposive value-laden interpretational approach allows judges to take into account more considerations and to weigh a provision against the constitutional values. Other issues discussed pertain to how institutional guidelines such as the doctrine of precedent and separation of powers, to a lesser extent, play a role in how judges interpret the law. It is demonstrated that the doctrine of precedent does not limit the role of judges but rather contributes to maintaining certainty, predictability and coherence in the legal system. It is also noted that judicial discretion is the mechanism by which judges use extra-legal factors such as public policy and moral considerations to assist in interpreting legislation.

- Description: Intermittent energy and water supply are current challenges faced by many residents in South Africa. South Africa is one of the more water scarce countries in the world; this coupled with the lack of infrastructure makes it challenging to provide every citizen with their right to basic water and sanitation. With millennium development goal 7C not being addressed in many areas, residents experience sub-standard living conditions, which drastically increases the vulnerability of marginalised groups to epidemics. In the sustainable development goals improving sanitation and drinking water has been identified as one of the most effective and least expensive means of reducing fatalities and increasing public health. There is a need for a mobile laboratory that demonstrates power and water self-sufficiency, which is capable of on-site diagnosis and water treatment. The unit will have the ability to perform independent compliance monitoring of municipal water supply, treat inadequate water and provide surplus electricity to surrounding areas. A literature-based study was performed utilizing several scientific databases to identify current methods of power and water production in previous disaster management and humanitarian relief situations. Based on findings three example laboratories were theoretically designed; structural modelling, systems simulation and optimization and sensitivity analyses were performed with HOMER Pro, PackVol and SketchUp. A cost benefit analysis was performed with the social return on investment methodology. Novel human waste processing was performed with fly ash and simulated faeces. Bacterial species identification in ice samples was performed with the API 20E protocol and limited equipment as a proof of concept for field deployment. A hybrid system consisting of PV panels, a wind turbine and biomass generator showed promise for displaced humanitarian relief camps; with every 1 ZAR capital invested resulting in 3.13 ZAR social benefit. A system consisting of PV panels and a battery bank proved to have the least environmental impact and the grid supply laboratory showed a cheaper cost of energy alternative for needs provision. Fly ash showed potential as in nutrient recovery and as a fertility aid to soil. The units developed function as a means to increase disaster preparedness and humanitarian relief as well a means to improve quality of life for rural marginalize populations.

- Description: The research provides an insight into the main challenges of previous Organisation Development processes, and Appreciative Inquiry is explored to establish the value it can offer as an alternative which minimises these challenges in today’s organisations. Organisation Development originated during the early 1950s and has evolved, adapted and changed dramatically since then. Two classical Organisation Development processes, Lewin’s 3-Step model and the Action Research spiral, are described, and typical challenges of applying them in today’s organisations are outlined. To remain competitive, organisations need to identify, adjust, and adapt to changing circumstances. These changing circumstances are constant and are due to increasingly complex demands from technological, economic, managerial, and cultural needs. Appreciative Inquiry as an approach is explored as an alternative Organisation Development process: it shifts the question from ‘what is going wrong’ to ‘what is going right in the organisation’. Appreciative Inquiry consists of the Discovery, Dream, Design and Destiny stages, and searches for the best in people and their organisations. In accordance with the constructionist paradigm, the research offers conclusions through the confirmation of past practices, conversations and relationships combined with creative new methods or experimentation of a positive intended future. The One- Group Pretest-Posttest, as a design, was selected to explore the effect of the variable (the Appreciative Inquiry intervention) in relation to the pre- and post-experimental evaluation. The design consists of an initial engagement (Pretest), the influencing variable (an Appreciative Inquiry intervention) and final engagement (Posttest) with the same group. The research was supported by a mixed method approach, with qualitative data supported by quantitative data. The quantitative data provided a general understanding of how participants experienced the change interventions. The qualitative data provided the information on how respondents experienced Organisation Development before an Appreciative Inquiry intervention and their views after an Appreciative Inquiry intervention. A South African secondary school was selected as a research site. Limited research is available regarding the application of Organisation Development and especially Appreciative Inquiry as a process in schools in general, and in South African schools in particular. A survey questionnaire was the instrument for collecting the quantitative data regarding the participants’ biographical information and change process perceptions. For the collection of qualitative data, interview questionnaires were used. The findings indicate that whereas previous change processes appear to have regarded the various staff levels of the school as separate entities, during the Appreciative Inquiry approach all staff were included as being an integral part of the organisation. The main finding after completion of the Appreciative Inquiry intervention was that collectively discussing and defining issues in a positive light instead of a problem to be solved changes the perspective of participants. Through the application of the Appreciative Inquiry’s four stages, participants were invited to think in a new way by applying innovation, enhancing participation, maintaining a positive core, and providing practical solutions through provocative statements. Conclusions reached from the research are that Appreciative Inquiry is a viable alternative for minimising Organisation Development challenges in contemporary organisations. The conclusions are based on factors such as understanding the reason for change; strong leadership; defining what is a successful intervention; understanding the Appreciative Inquiry process, the value of provocative statements; and the sustainability of change.

- Description: South African health care organisations are required to adhere to the National Health Act, 61 of 2003 which contains the national core standards. Clinical governance is a key domain within the national core standards and is directly involved with a health care organisation’s ability to deliver quality care services. It can be described as a framework that ensures doctors and health care employees collaborate to provide superior quality health care services and create clinical accountability. The aim of this research was to evaluate the role of clinical governance within a private radiology organisation in Durban, KwaZulu-Natal (KZN). The goals of this research was to identify and explore the challenges that are associated with clinical governance within a private health care organisation in Durban, KZN. Furthermore, to evaluate the importance and implications of clinical governance for a private radiology organisation in Durban, KZN. The objectives of this research was to investigate how the private radiology organisation is managing clinical governance and to identify whether there is a common understanding of the concept among its members. The research adopted a qualitative approach where semi-structured interviews were conducted to obtain the data that enabled the goals and objectives of this research to be attained. The results indicated that clinical governance is a key factor to the private radiology organisations long-term sustainability. Clinical governance is vital for health care organisations to deliver quality health care services. The private radiology organisation places a significant emphasis among its members to deliver superior quality health care services. As a result, the organisation utilises the key elements within the clinical governance framework to continuously increase the quality of care that it provides and abide to the legally binding standards. The results support the notion that there is a need for the clarity of the definition, roles and responsibilities of clinical governance. The findings of this research suggest that further research is required to identify the contribution that clinical governance makes to improving the quality of care within South African health care organisations. Furthermore, research identifying employees’ perceptions of clinical governance within the private health care sector in South Africa is recommended.

- Description: Higher education institutions are faced with pressure to change to meet academic as well as socio-economic needs. These changes are often aimed at achieving financial viability, increased institutional efficiency, and solving problems of fragmentation in the university. Universities can change in their structure, operations, systems, or and in the use or adoption of technology. The effective implementation and management of these requisite changes is the key challenge to organisations facing change. Walter Sisulu University, a comprehensive university in the Eastern Cape, has formulated a strategy to turn the university around. Included in the strategy is a project on the academic enterprise. The level of readiness for change is viewed to be a determining factor in making any change successful. Since readiness is not automatic, there is a need to prepare individuals to have a positive attitude towards the change and to embrace the proposed change initiative. This study is informed by the quest to know what will encourage and prepare employees for the implementation of the new Programme and Qualification Mix (PQM) at the University. The study therefore sought as its main purpose to explore factors influencing individual readiness for change in the PQM at Walter Sisulu University. A qualitative approach was adopted in the study. Models of change readiness were reviewed to identify themes that would be used to explore the levels of readiness amongst university academic employees who were to implement the new Programme and Qualification Mix. Documents were analysed to understand the change in PQM and face-to-face, semi-structured interviews held to solicit the views of academic employees regarding enablers or inhibiters of their readiness. Results highlighted the poor preparation of academic employees at Walter Sisulu University to support and implement the change. Key concerns of employees included dissatisfaction with the inadequate and inappropriate communication strategies, uncertainty about the suitability of the changed PQM, doubt regarding leadership support for change, as well as the perceived risk of the change. However, the main enablers were the comprehension by WSU employees of the need for a new PQM to address the poor alignment with university vision and HEQSF requirements, an appreciation of the lack of social relevance of the programmes, and confidence that they have the requisite skills and qualifications. The perceived benefits for the institution provided the needed spur for embracing the new PQM.

- Description: Measurement is acknowledged to be a critical component in mathematics education and is particularly important for vocational Engineering students, for whom this is a key skill required in the workplace. The goal of this research was to explore the existing measurement conceptualisations of vocational Engineering students at the outset of their course, as evident in their engagement with mediated measurement tasks. The focus on students’ prior knowledge in measurement, was for the value that this awareness holds in understanding the learning needs of the students. Students participated in five measurement tasks. Four took the form of dynamically assessed task-based interviews, and the fifth was a written test assessing what they had learned during their Mathematics classes. Domains of measurement that were assessed in these tasks included length, area, surface area, volume and flow rate. The interviewer took the role of mediator and students were assessed according to the number of moments of mediation and the degree of mediation required to successfully complete the task. Students’ responsiveness to this mediation provided insight as to their conceptualisations of the measurements relevant to the task. This research was exploratory in nature and adopted an open and flexible approach to the data analysis. Critical incidents were identified and coded according to the mediation offered and the actions of the students during the measuring activity. This allowed patterns to emerge that revealed stable and emerging conceptualisations that related to embodied and symbolic aspects of measurement. Evidence was found that for many of these students the link between the embodied and symbolic aspects of the concept was broken. This insight allowed suggestions to be formulated about how better to facilitate these students’ learning of measurement.

- Description: The purpose of this study was to identify and analyse in an historical context the major changes to the United States’ Internal Revenue Code during the period 1981-2001. This qualitative study relied on historical and legal interpretative approaches to better understand the political forces, personalities, and interactions that helped shape the legislative changes during this time period. The study focused on deep analysis of primary sources that best illuminated the latent narrative of four major tax actions: The Economic Recovery Tax Act of 1981, the Tax Reform Act of 1986, The Omnibus Budget Reconciliation Act of 1993, and The Economic Growth and Tax Relief Reconciliation Act of 2001. Archives, periodicals, and political rhetoric were examined in order to help shape the historical narrative. In addition, this study sought to identify major trends and paradigm shifts in the way United States tax policy was formed during the time period examined. The study identified several key trends that emerged in United States’ tax policy during this period: the use of budget deficits as political tools; factors associated with accomplishing tax reform; gaps between political rhetoric of individual politicians and their political action; and the virtual disappearance of a political middle ground in United States budget politics. The study concluded by noting the economic and political significance of budget deficits and stressing the need for fundamental changes in voter responsibility in helping achieve lasting, broad-based tax reform and budgetary responsibility in the United States.

- Description: The reform and transformation of education systems in terms of enhancing Science, Technology Engineering and Mathematics (STEM) education in the schooling systems is gaining momentum in different parts of the world. It is argued that there is a need to enhance science education, particularly in Africa, because science education is considered to be the main vehicle through which the greater objectives such as national development and improvement in the quality of life can be realised. Namibia as a country is no exception. A key way through which science education can be enhanced is through carrying out practical activities during teaching and learning. Despite the crucial role that practical activities play in science subjects, it appears that they are not carried out in most of the Namibian science classrooms. It is against this background that this study explored an intervention on how easily accessible resources to carry out hands-on practical activities in science, influenced science teachers’ conceptual development and dispositions towards the use of practical activities in science. In this study, a mixed methods case study approach underpinned by an interpretive paradigm was adopted. The research was conducted with 21 in-service science teachers from schools in Namibia who were all on a two year part-time BEd (Honours) program delivered in Namibia by a South African university from the Eastern Cape. To generate data, document analysis, questionnaires, semi-structured interviews, an intervention in the form of workshops on practical activities, lesson observations, which were videotaped, as well as teacher reflections were used. Conceptual development, disposition and professional development served as the conceptual lenses. Vygotsky’s sociocultural theory in conjunction with Shulman’s pedagogical content knowledge (PCK) were the theoretical frameworks adopted in the study.The findings showed that there was a general perception among the participants before the intervention that in order to carry out practical activities, well-equipped laboratories, conventional chemicals and equipment are needed. Some teachers had never used practical activities in their science classes with a range of constraints or hindrances provided as reasons. The findings additionally showed that for teachers to use easily accessible resources to carry out practical activities in their science classrooms, they need the knowledge and exposure on how to use these resources. The findings thus showed that this professional development approach raised motivation, knowledge and the skills of the science teacher participants to include practical activities in their science lessons using easily accessible resources. A recommendation is that if teachers are given opportunities, through professional development platforms to engage in hands- on practical activities using easily accessible resources, they can be enabled and motivated to implement these in their science classrooms.

A recommendation is that if teachers are given opportunities, through professional development platforms to engage in hands- on practical activities using easily accessible resources, they can be enabled and motivated to implement these in their science classrooms.

- Description: Assessment is an integral part of the teaching and learning process. Research by the Assessment Reform Group (ARG) (1999) and others has shown that assessment for learning, or formative assessment, is one of the most powerful educational tools for promoting effective learning and improving performance. Assessment for learning (formative assessment) and summative assessment form part of most national education policies and is advocated in the Namibian curricula. However, most of the focus of official programs in Namibia has been on summative assessment resulting in assessment for learning being neglected. It is against this backdrop that this study investigated science teachers’ conceptions of, and dispositions towards, the implementation of assessment for learning during science practical lessons. In this study, a mixed methods case study approach underpinned by an interpretive paradigm was adopted. The research was conducted with 25 in-service science teachers from schools in Namibia who were all on a two year part-time BEd (Honours) program delivered at NIED in Namibia by a South African university from the Eastern Cape. To generate data, document analysis, questionnaires, semi-structured interviews, an intervention in the form of workshops on assessment for learning, practical activities, lesson observations (which were videotaped), as well as teacher reflections were used. The lesson observations were conducted in two schools in the Omusati region of Namibia. The theoretical frameworks guiding the study were Vygotsky’s social constructivist theory and Shulman’s pedagogical content knowledge (PCK). The findings of the study revealed that teachers held different notions toward assessment for learning before the intervention in the form of a workshop. However, after the workshop the teachers demonstrated understanding of what assessment for learning entails and how it can be implemented during hands-on practical activities using easily accessible resources. A recommendation is that if teachers are given opportunities, through professional development platforms, to engage in hands-on practical activities using easily accessible resources and an appropriate orientation towards assessment for learning that includes model strategies they can be enabled and motivated to research and begin to implement assessment for learning in their science classrooms.

- Description: This study investigated pre-primary teachers’ perceptions of the causes of disparities in the literacy readiness of pre-primary learners. The aim was to understand the reasons that teachers ascribe to differences in literacy readiness; ways in which teachers’ understanding of the causes may relate to their practices and to learners’ literacy readiness levels. The study drew from Bernstein’s pedagogic discourse as the theoretical framing and analytical tool for engaging with the data. The participants in the study were three pre-primary teachers practising in a variety of schooling contexts. In a quest for a deeper understanding of the causes, data for the study was generated using multiple sources. Structured interviews were employed to get the teachers perceptions, while classroom observations were aimed at discovering ways in which the teachers’ points of view related to their practices in the actual classroom. An analysis of documentary evidence was carried out to understand ways in which teachers’ practices adhered to the curriculum intentions, as well as ways in which their plans and curriculum documents supported the development of the emerging literacy skills of the learners. Findings of this study indicated that teachers attributed disparities in the literacy readiness of learners to factors external to the classroom and it was found that their pedagogic practices, as a result of these perceptions, were not supportive to the development of literacy skills that are pivotal for transitioning to Grade 1. The study has implications for curriculum reform, sensitization of stakeholders and teacher training in order to ensure a solid and promising academic foundation, and consequently, a successful academic future for all pre-primary learners.

An investigation into the effect of an Extensive Reading Programme on bilingual Grade 3 learners’ reading attitudes in two primary schools in Grahamstown

- Description: The focus of this study is to explore formative intervention of a bilingual Extensive Reading Programme (ERP) in two Grade 3 classes in Grahamstown, South Africa. ERP involves access to large quantities of reading materials for pleasure and to reading opportunities (Bamford & Day, 2002; Krashen 2004). The current focus on measurable reading achievement in clearly defined areas such as vocabulary, fluency and comprehension has resulted in reduced attention towards the affective component in relation to literacy development, and links attitudes to reading success. This study helps to fill this gap by examining the effect of an ERP on the reading attitudes of Grade 3 learners. The study draws on Cultural Historical Activity Theory (CHAT) to make sense of learning and social change through mediation, scaffolding, interaction and collaboration learning. The ERP is located within a broad framework of literacy and incorporates a balanced reading approach implemented in an informal reading setting so as to motivate, encourage and nurture reading for enjoyment. This formative intervention used expansive learning cycles to develop a responsive ERP that was implemented and evaluated to investigate its effects on learners’ reading attitude. There were three phases (pre-, during- and post- intervention) that were designed over 31 weeks where rich, qualitative data was collected from questionnaires, observations, learners’ drawings and interviews. To make sense of this data, concepts from CHAT such as contradictions, expansive learning, double stimulation, transformative agency and sustainability were used (Engestrom & Sannino, 2010; Haapasaari & Kerosuo, 2015; Saninno, 2015). In addition, Mathewson’s (1994) reading attitude model addressed the attitudinal aspects of the study whilst a multimodal social semiotic perspective (Kress & Van Leeuwen, 1996) was used to analyse learners’ drawings. The findings of this study demonstrate the effectiveness of combining top-down and bottom-up reading methodologies. In both research sites there was appreciable change in the number of books learners read. Learners also began to volunteer to read and participated in book talks. Through access to a variety of reading materials and reading opportunities, learners demonstrated agency, criticising some ERP practices and modelling new ways, thus claiming and sustaining the reading programme. Being provided with a safe, informal learning context where reading was presented as a social activity, learners gained confidence, engaged in meaningful discussions and improved their self- esteem. Finally, learners continue to access these resources even beyond the research programme.

- Description: Poor learner performance in mathematics has a long-standing record in South Africa. More than two decades after attainment of democracy South Africa is still seeking ways of addressing this crisis. Research around poor mathematics points to a number of factors, however, the dominant being that South African teachers lack both mathematics content and the pedagogical knowledge to teach it effectively. Ball, Thames and Phelps (2008) refer to the knowledge to teach mathematics effectively as Mathematics Knowledge for Teaching [MKfT]. MKfT combines the knowledge of both the content with the pedagogical skills. Mathematics teachers in South Africa are said to lack MKfT to teach mathematics in ways that enhance conceptual understanding and the effect of this deficiency is felt as far back in the education system as Foundation Phase. Research suggests Foundation Phase teachers do not develop the learners’ number sense well enough to equip them with essential mathematical strategies and proficiency that would help them learn mathematics with ease and understanding. This deficit expands as learners move up the grades. My qualitative research, case study approach was employed to investigate MKfT enacted in the teaching of an expert Foundation Phase teacher, which she used while developing number sense in her Grade Two learners. A key aim is to inform fellow Foundation Phase teachers and Foundation Phase teacher educators, both in-service and in-training, of the key aspects of MKfT required in developing number sense. The study found that Foundation Phase teaching requires employment of all the domains of the MKfT to develop number sense to Grade 2 learners. These domains are complexly interconnected and interdependent and the research shows that while one needs the full set to be able to teach effectively, the expertise becomes visible in the seamless and somewhat automated interweaving of these domains. Furthermore, the research will illuminate how such seamless and automated interweaving can render the individual domains difficult to discern.

An investigation into the origin and evolution of the Tierkloof Wetland, a peatland dominated by Prionium serratum, in the Western Cape

- Description: The Tierkloof Wetland in the Western Cape has been damaged through erosion down to bedrock with gullies that are up to 50 m wide and 7 m deep. The purpose of this study was to investigate the origin and evolution of the Tierkloof Wetland and consider the role both natural and human-induced processes have played in its degradation. The main methods used were digital mapping using GIS software, satellite and aerial photographic interpretation of past and current land use, detailed topographic surveying, coring to bedrock, stratigraphic analysis of valley-fill sediments, and radio carbon dating of peat samples. Nine GIS-produced topographic profiles across the valley were plotted to analyse downstream changes in valley width and morphology along the length of the Tierkloof valley. Detailed cross sections of the stream channel were produced using topographic survey data. Depth to bedrock analysis indicated that there is evidence of a degree of planing of bedrock over geological time periods. Survey data indicates that the longitudinal slope of the former wetland surface is remarkably uniform over most of its length and there is an overall thinning of the valley fill from the head to the toe of the wetland. The stratigraphy and associated organic matter content of the wetland soils showed that the sedimentary fill varies considerably. There are appreciable accumulations of organic sediment, including sandy peat and peat layers with organic content of up to 50 %. The two radio carbon dates obtained from the gully wall midway down the Tierkloof Wetland suggest that peat accumulation started following the last glacial maximum. The peat has accumulated consistently and is mostly associated with the growth of the palmiet, Prionium serratum. Evidence from past and current land-use activities from aerial photographic interpretation show that natural vegetation in the Tierkloof Wetland has been severely degraded, alien plants are extremely common, and road-building and artificial drainage in the wetland have influenced fluvial processes. It is likely that these activities, exacerbated by the high rainfall events in the early 2000s, have triggered the erosional phase that was initiated a few decades ago. However, longer term processes (thousands to tens-of-thousands of years), such as the planing of the bedrock, also indicate that erosional processes have been a natural part of the Tierkloof Wetland development. A conceptual model of wetland development is thus proposed, based on long-term erosional and depositional processes that are linked with climate change and the current aggradation phase of peat formation that is being driven by the ecosystem engineering processes of palmiet plant growth. It is further suggested that relatively recent land-use activities have resulted in an already vulnerable wetland, in geomorphological terms, to cross a threshold to become a severely degraded, gulley- dominated wetland.

- Description: This study explores the way Zambian women make sense of the representations and discourses in the Latin soaps that they watch daily. The study seeks to find out what pleasures and values Zambian women get from these soaps given that the Latin and Zambian cultures are very different. This is in the context of Zambia being a socially conservative patriarchal and Christian nation, where the legal and traditional practices focus on the authority of the man in relationships, particularly in marriages. The lens through which this study is conducted is provided by the media imperialism thesis and its critiques. The study explores the underlying proposition of the thesis that global media are uncritically received by people in the Third World which contributes to global cultural homogenisation. Drawing on ethnographic critiques of this position, my study provides a close examination of actual viewers in actual contexts in order to understand the complex relationships that often exist between global media and local audiences. Using qualitative methods rooted in reception analysis, the study explores the pleasures women get from these soap operas and in particular, the symbolic means that these soaps provide for what has been referred to as ‘symbolic distancing’. Symbolic distancing foregrounds the way local audiences use global media to distance themselves from the cultural confines of their local environments, exposing them to other worldviews and understandings from which they can critique their own lived conditions of existence. In line with this, the study evaluates whether the viewers’ perceptions and values have been changed by the viewing of these Latin soaps.
