- Description: The primary activity of water boards is to provide water services (bulk portable, and bulk wastewater) to other water services institutions within its respective service areas. They may perform other activities under conditions set out in the Water Services Act of 1997. Water boards’ revenues come from the municipalities they deliver services to. Not all municipalities have been paying for the services delivered to them, which led to the aim of this study being to gauge the perceptions of Water Board X and Water Board X’s customers of selected Customer Relationship Management (CRM) factors (service quality, customer involvement, customer value, information technology, and management commitment) that may possibly influence Revenue Management (RM). This could possibly assist Water Board X in the future to improve its revenue and debt collection. This thesis employed an interpretivist qualitative research methodology to explore its research aims and objectives. Open-ended semi-structured interviews were conducted with thirteen participants from Water Board X and four municipalities which Water Board X provides services. The data collected from the interviews were analysed manually through thematic analysis. The outcome of the interviews noted that an organisation that delivered high levels of service quality to its customers, could possibly improve its RM as the customers are of the opinion that their needs and requirements have been met and would be willing to pay for the services rendered. It was furthermore found that an organisation that involves its customers could possibly improve its RM as the organisation constantly communicates with its customers during, for example, the different stages of a project to ensure that the organisation does not deliver a project that does not meet the customers’ requirements at the end of the project life cycle. In addition the use of information technology played a pivotal in an organisation as the use of information technology assisted to develop effective methods in customer relationship management such as, data management, improving communication within the organisation, and with the customers, and the decision making. Furthermore, this study suggested the importance for an organisation to add value to the services that they deliver and for an organisation’s management to be committed to ensure that their customers’ expectations and requirements are met. The findings of the study suggest that CRM factors (service quality, customer involvement, customer value, information technology, and management commitment) could influence RM, and it is suggested that Water Board X adopts CRM strategies accordingly to improve its RM. Some of these strategies include adopting a coherent and sustainable revenue strategy through the use of appropriate tariff structures that are simple, equitable, affordable, financially sustainable, and transparent for all; showing commitment by prioritising water loss management and by properly auditing water supplies and water treatment revenue while increasing efficiency in supply and revenue recovery as this allowed Water Board X to better serve its customers, improve its financial standing, and allocate funding for water infrastructure upgrades and to adopt technologies that are on the market as these technologies can detect leakages, manage payments, control water flow and transmit data. , Thesis (MCom) -- Faculty of Commerce, Department of Management, 2021

- Description: Description Advances in electronics manufacturing have made robots and their sensors cheaper and more accessible. Robots can have a variety of sensors, such as touch sensors, distance sensors and cameras. A robot’s controller is the software which interprets its sensors and determines how the robot will behave. The difficulty in programming robot controllers increases with complex robots and complicated tasks, forming a barrier to deploying robots for real-world applications. Robot controllers can be automatically created with Evolutionary Robotics (ER). ER makes use of an Evolutionary Algorithm (EA) to evolve controllers to complete a particular task. Instead of manually programming controllers, an EA can evolve controllers when provided with the robot’s task. ER has been used to evolve controllers for many different kinds of robots with a variety of sensors, however the use of robots with on-board camera sensors has been limited. The nature of EAs makes evolving a controller for a camera-equipped robot particularly difficult. There are two main challenges which complicate the evolution of vision-based controllers. First, every image from a camera contains a large amount of information, and a controller needs many parameters to receive that information, however it is difficult to evolve controllers with such a large number of parameters using EAs. Second, during the process of evolution, it is necessary to evaluate the fitness of many candidate controllers. This is typically done in simulation, however creating a simulator for a camera sensor is a tedious and timeconsuming task, as building a photo-realistic simulated environment requires handcrafted 3-dimensional models, textures and lighting. Two techniques have been used in previous experiments to overcome the challenges associated with evolving vision-based controllers. Either the controller was provided with extremely low-resolution images, or a task-specific algorithm was used to preprocess the images, only providing the necessary information to the controller. , Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2021

- Description: The last 30 years since the early 1990s has seen the heightened promotion of organic farming as a sustainable farming option in Zambia. The main objectives of this research study were to carry out an analysis of organic farming systems in order to understand factors affecting adoption, as well as reasons why some organic farmers discontinue using the approach. The study involved four districts in Zambia: Mazabuka, Chikankata, Lusaka and Chongwe. Specifically, the research investigated challenges and limitations of organic agronomic practices, and analysed factors that influence adopters and disadopters of organic agriculture. Primary data were collected through interviews and by administering semi-structured questionnaires. The research population comprised approximately 250 farmers adopters and disadopters, with the sample size being 50 farmers chosen across four districts using systematic random sampling methods. Additionally, five observation research field trials were conducted in order to gather practical data on individual farmer’s crop management practices. Farmers adopting and maintaining organic methods reported several reasons for embracing the system, some of which are: organic farming is regenerative; it is environmentally responsible; it uses manure, believed to help build healthy soils rich in organic matter with better nutrient and moisture holding capacity; pesticides and synthetic fertilizers are not used, reducing the levels of toxic residues in organic products which ultimately promotes health. Labour constraints, pest and disease challenges and weed problems were some of the reasons for disadoption. Data showed that disadopters had lower education (48% had primary education), were older and with slightly more children. Although there were more women adopting organic agriculture compared to men, the difference was small 56% and 44% women and men respectively. Among disadopters there were more women (67%) compared to men (33%). Overall, the study results suggest that promotion of organic agriculture should be encouraged through liaison with government departments such as the Zambian Department of Agriculture to include organic agriculture when developing policies. In general, organic farmers have positive opinions concerning the benefits resulting from organic agriculture. Organic farmers should enjoy equal opportunities to conventional agriculture in the provision of extension services, input support, infrastructural development, access to financial resources to procure farm machinery, and equipment and most important of all, they should get fair prices for their organic produce and products. , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2021

- Description: The World Bank has emphasized the role of savings in financing domestic fixed capital formation, technology, education, employment and economic growth. Many African countries have experienced decreased savings and increased current account deficits worsened by the global financial crisis and capital outflows. This study seeks to explore the determinants of savings and determine the savings trend of African countries compared to that of the world. To this end, annual time series data for 20 representative countries from different economic groups were obtained from World Bank Indicators, International Monetary Fund (IMF), Penn World Tables and Integrated Network for Societal Conflict Research (INSCR) database over the period 2000 to 2018. The Panel ARDL/ Pooled Mean Group estimator was used to analyse the data. The main findings were that household variables, capital flow variables, human capital variables, institutional quality variables, financial and other social macroeconomic variables determine savings. Further, the speed of adjustment show causality from the explanatory variables to savings. The use of income and monetary policy dummy variables indicates that there is no difference in determinants of savings for countries with different income groups and monetary policies. It was recommended that African countries invest in education and ICT infrastructure, improve their financial systems and restructure policies on good governance and political stability as this has a significant effect on savings. The study was limited by a lack of time series data for all African countries, therefore, future research involving an increased sample size and variables were recommended. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2021

- Description: Significant research has been conducted on the sustainability, productivity, maintenance, improvement and the development of the agricultural sector. For this reason, there is increasingly more technology that is being adapted and used in the agricultural arena. New technology (Disruptive technology) in the wool value chain has the ability to significantly disrupt the typical business models of wool brokers in South Africa, and as a result, key uncertainties exist with regard to its future sustainability. This study investigated the importance of sustainable disruptive technology that is implementable at wool brokers in South Africa. This was done through secondary research, creating a proposed conceptual business framework that would make use of various disruptive technologies such as; digital wool auction, RFID and blockchain technology to enhance interventions that are needed to create sustainability amongst wool brokers in South Africa. The enhanced proposed sustainability is created through by creating socio efficiencies, environmental efficiencies and operational efficiencies in the form of safety, Traceability and Operational efficiencies as Intervening Variables. Questionnaire statements were developed by the researcher from the literature review that was conducted and consulting experts in the field of the agriculture fibre industry and also in the wider sphere of agriculture. The instrument used in this study was used to measure the hypothesised models based on the influence of independent variables of a disruptive nature on the interventions that would allow for the perceived sustainability for wool brokers in South Africa. From the data analysis of the feedback received, a Revised Proposed Framework to enhance the sustainability of Wool Brokers in South Africa using disruptive Technology was created. From the research it is evident that new technology, such as disruptive technology, in the wool value chain has the ability to significantly disrupt the typical business models of wool brokers in South Africa and, as a result, address the demands of the end consumer to ensure the future sustainability of wool brokers. , Thesis (MA) -- Faculty of Business and Economic Sciences, Nelson Mandela University Business School, 2021

- Description: The South African perlemoen abalone (Haliotis midae) may be vulnerable to rising temperatures on the East coast of South Africa due to climate change. H. midae is South Africa’s most valuable aquaculture species, and it is thus important to understand its physiological ability to adapt to the expected changes and to identify possible management measures to mitigate the impacts of rising temperatures. This project aimed to understand thermal tolerance and growth rates of offspring from two H. midae populations originating from the warm-temperate Central region (Port Elizabeth) and warmer Eastern edge of the species’ distribution in the Transkei region. To determine the effects of temperature on the physiological performance of the two abalone populations, growth rates, oxygen consumption rates and critical thermal maxima (CTM) were compared. A laboratory growth trial was conducted at three controlled temperatures, visibly, the ‘optimal’ temperature for H. midae growth (18 - 20℃), ‘pejus’ (stressful) temperature (21 - 22℃) and ‘critical’ temperature (23 - 24℃). Oxygen consumption rates were recorded at optimum (20℃), pejus (22℃) and critical (24℃) temperature using a respirometer. In addition, a farm growth trial with simultaneously spawned cohorts of abalone from the two populations was conducted at ambient temperature (19.5 and 20.0℃). The laboratory growth trial revealed no significant differences in growth rate between the two populations at the three temperature treatments (ANOVA, P > 0.05; df = 2). However, mortalities were high and growth rates low, indicating that the rearing conditions were sub-optimal, possibly masking genetic differences. No significant differences were observed in oxygen consumption rates (ANOVA, P = 0.18; df = 2), and CTM (t-Test, P = 0.31; df = 3) between the two populations. The CTM for both populations was between 29 - 30℃. The farm trial yielded no significant differences in growth rate during the Nursery phase (t-Test, P = 0.25; df = 2), however significant differences in growth rate were observed during the grow out phase with the Central region abalone offspring growing faster than the Eastern edge population (t-Test, P = 0.04; df = 4) indicating the possibility of a genetic difference between the two populations. Further experiments will be required to determine whether the differences observed in the growth trial were genetically or environmentally induced. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2021

The CTM for both populations was between 29 - 30℃. The farm trial yielded no significant differences in growth rate during the Nursery phase (t-Test, P = 0.25; df = 2), however significant differences in growth rate were observed during the grow out phase with the Central region abalone offspring growing faster than the Eastern edge population (t-Test, P = 0.04; df = 4) indicating the possibility of a genetic difference between the two populations. Further experiments will be required to determine whether the differences observed in the growth trial were genetically or environmentally induced. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2021

- Description: There has been a gaping variance between the number of mobile phone users and landline users in South Africa (RSA). Results from an assessment in 2011 suggested that 29 million South Africans subscribed to mobile phones versus 5 million landline users (Balabanoff, 2014). The exponential growth of mobile applications has been precipitated by the increased growth of the mobile phone market. This growth is coupled with numerous advantages that mobile services bring to the user, such as better operability, productivity advances and entertainment (Balabanoff, 2014). Even though adoption strategies regarding mobile banking have been studied in various parts of the world, acceptance of mobile banking applications in South Africa has not been greatly researched. Hence, this study focused on exploring consumer behaviour and acceptance towards adopting mobile banking in South Africa, where mobile banking is at an elementary stage, but provides potential benefits to both users and business at large. A quantitative research style was followed by this research. An electronic quantitative questionnaire was distributed to South African civilians who are eligible to hold bank accounts in their own names. The research was then conducted on a sample size of 86 respondents. Due to limitations on time, this study utilised convenience sampling. Data gathered from the questionnaires was examined using statistical analysis to scrutinise the correlation between the variables used in the research model, this being Unified Theory of Acceptance and Use of Technology (UTAUT) model. The UTAUT is commonly used to predict and explain factors that influence the adoption of technology by users. These factors help decision-makers in formulating technology acceptance strategies. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: Fires are common in South African savanna habitats, which can disrupt the dynamics of entire invertebrate populations, endangering biodiversity and the environment. The aim of this study was to look at how fire frequency affected invertebrate population dynamics and biodiversity in a 41-year-old fire experiment at the University of Fort Hare research farm in Alice. The experiment had six different levels of burning frequency: no-burn (K), annual burn (B1), biannual burn (B2), triennial burn (B3), quadrennial burn (B4), and sexennial burn (B6). The experimental plots were replicated two times in a randomized complete block design and have been continuously retained since 1980. A ground yellow mustard solution was used to collect earthworms, which were then identified by an earthworm taxonomist. Pitfall traps were used to collect ants and other insects, which were then identified under a microscope. In total, three soil samples were collected from each plot to assess selected soil nutrients, moisture, and pH. The Shannon diversity index, richness, and population of earthworms, ants, and other insects were calculated, and a one-way ANOVA analysis was done to check if the treatments differed significantly. A correlations study was used to look for any influence connected to soil parameters, including the Shannon diversity index, species richness, and density of soil invertebrates. According to our findings, the measured parameters did not show any significant differences in the measured parameters between the different frequency levels. All the plots had two species of earthworm , Proandricus timmianus and Proandricus beddardi except the biennial burn plot, which had all three, the afore mentioned species and one other unidentified species, Proandricus sp. The triennial burn treatment slightly enhanced the insect diversity, richness, and evenness of ant species difference while the diversity, evenness, and richness were lowest in the sexennial burn plot. However, there was no signif difference in population. After B4, the no burn plot had the second largest diversity and species richness, and the third highest species evenness and had a 100 percent species similarity index. The ants were evenly distributed in the no burn plot compared to the other plots, with K having a lower density than the other plots except for B4, K being slightly more diverse than B6, and B1 with a slightly lower diversity than the other plots, and it being the third species rich plot after B2 and B3, followed by the rest of the plots. This study implied that fire frequency has an insignificant impact on invertebrates’ communities in Savanna biomes words.icant , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

- Description: The primary research objective of this case study was to understand the effectiveness of cost containment measures implemented by all departments at Harry Gwala District Municipality. The case study also explored factors that may have contributed to the implementation of cost containment measures to ensure that the municipality spends funds on essential items and avoids unauthorised expenditure. A case study with fourteen (14) participants was chosen in order to focus on a particular area that the researcher could easily monitor. The researcher mixed qualitative and quantitative research designs to maintain the strengths and improve the weaknesses in both designs. Audited Annual Financial Statements and approved budgets were analysed to assess the effectiveness of cost containment measures. The study found that while employees were aware of their roles and responsibilities, it is safe to say that they did not follow procedures to ensure that costs were maintained. The results of the study showed that the Municipal Public Accounts Committee (MPAC) had no financial background. There was generally no change in the behaviour of employees as far as cost containment measures were concerned. The current repairs and maintenance budget was far below the norm of 8% of the carrying value of municipal assets and the municipality only budgeted between 2 – 3% per year for the assets with a carrying value of about R2.3 billion. , Thesis (MBA) -- Faculty of Business and Economic Sciences , Business Administration, 2021

- Description: This study investigates the impact of the level of education and education spending on economic growth in the Southern African development community (SADC) using annual panel data from 1995 to 2017 using the FMOSLS and DOLS cointegration estimators. Three levels of education are identified in study (primary, secondary and tertiary). Moreover, we create an index of government spending on education corresponding to these three levels of education. The empirical results suggest that there is a positive long-term relationship between secondary education and economic growth but not for other levels of education. Moreover, it is found that only government spending at primary and secondary education contribute to economic growth. The causality analysis for confirm that only secondary education affects economic growth and is affected by government spending on education. Policy implications of the study are discussed. Government should be careful in managing the public spending on education in a way to increase the skilled labor. Education Policies must be drive based on principle. Professional schools must be first priority in education policies in the region. Government should direct the public expenditures on education towards productive sectors that will contribute in improving the standard of living contributing so on economic growth. , Thesis (MCom) -- Faculty of Business and Economic Sciences, Economics, 2021

- Description: Special Economic Zones (SEZs) have been a global phenomenon since the 1960s and have been integral to the transformation of emerging and ailing economies. In 2002 the South African government identified SEZs as instruments for advancing its economy into a higher industrialisation path based the assessment of potential socio-economic gains. Past research findings, however, suggest that South African SEZs, when compared to international SEZ performances, are lagging behind both in terms of delivering a compelling SEZ value proposition and achieving the desired socio-economic gains. Limited research has been conducted on the factors which enable and dis-enable the success of SEZs in South Africa. This study evaluates the factors that enable and dis-enable the effectiveness of South African SEZs in achieving their socio-economic development objectives. Applying a qualitative case study methodology, research was conducted on the East London Industrial Development Zone(ELIDZ), one of the first SEZs to be designated in South Africa in 2002. The study finds that a weak SEZ regulatory framework characterised by slow delivery of important SEZ industrial support has dis-enabled South African SEZs. A complex business environment has also dis-enabled the competitiveness of South African SEZs. The study reveals that while it is easier to conduct business inside the SEZs, South African SEZs are not given adequate policy latitude to be an experimental ground to drive reform that will improve the ease of doing business in South Africa. A challenging labour market marred by low productivity, high production costs and inadequately skilled labour continue to challenge the success of SEZs in South Africa. Poor regional infrastructure and delays in the roll out of fiscal incentives, are also some of the factors that have dis-enabled the success of the East London IDZ. World-class infrastructure inside the ELIDZ, inherent locational competitive advantages and the existence of locational-specific non-fiscal incentives have, however, been the key enablers that have improved the competitiveness of the ELIDZ. Despite some of the notable dis-enablers to the competitiveness of South African SEZs, the ELIDZ has done well in achieving short-term static outcomes such as employment, exports, investment attraction and FDI despite some of the factors that had dis-enabled the zone. The zone has also achieved certain dynamic outcomes such as skills upgrading, industrial upgrading, technology transfer and diversification of the economic output, albeit these still being at low levels. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: The lack of the female voice in relationships with men means that they cannot negotiate safe sex, friendships with both male and female peers, their freedom of movement within the parameters of their relationships, etc. As a result of this, HIV and teenage pregnancy rates remain unacceptably high. The public health sector in present-day South Africa finds itself increasingly strained due to high levels of new incidents of HIV in young women between the age of 18 and 24. Statistics show that pregnancies are on the rise due to early sexual interactions. These statistics stand in stark contrast with the fact that gender and sexuality are topics taught in the school system through subjects such as Life Orientation. The assumption is often that young people, and in the context of this study, young women, will translate the knowledge into skill sets and behaviours that would help them assert themselves more and have control of their bodies. The statistics, however, seem to tell a different story. The purpose of the study is to understand why, despite the fact that there are subjects in the school curriculum and programs offered by different organisations, HIV infection amongst young women as well as teenage pregnancies remain a problem, an indication that the female voice remains marginalised in intimate spaces. The theoretical frameworks for this study include a Humanising Pedagogy, interrogating education and training engagements for social change while also engaging with various works of Judith Butler as a lens to view the marginalisation of young women in a gendered society. This study is qualitative in nature as it uses a critical ethnographic research design. It aimed to uncover and understand the deeper meanings of the phenomena experienced by young women from their point of view. The study employed a non-probability, purposive sample technique, in addition to the ethnographic analysis. A sample of 15 young women between the ages of 18 and 24 in the Nelson Mandela Bay Metro engaged in the study. These young women were recruited from Rise out of School Programme, part of the Khethimpilo prevention program. Informed consent to participate in the study was secured before interviews were conducted and participants were not coerced into participation and were free to drop out at any point. All endeavours to protect participants from physical harm and mental stress were taken. Misconceptions and misunderstandings which arose in the piloting phase of the study were removed and complete confidentiality was maintained in the management of all information obtained about participants. Individual semi-structured interviews were conducted with the participants. Thematic analysis was used to analyse data.

- Description: The majority of new and existing small photovoltaic (PV) installations in South Africa are fixed-panel systems, largely due to the cost of photovoltaic panel components having reduced steadily in recent years where an increased requirement is met with a larger number of panels, whilst tracking system costs remain prohibitively expensive. Fixed installations realise only a part of their energy potential as they are truly effective for only short periods of the day. The aim of this study is to investigate and build on the current technology of PV tracking systems with the aim of specifying a simple control and actuation system which performs the tracking function. The eventual purpose of this thesis is to reliably produce more energy from solar photovoltaic installations than similar installations using fixed panels. This would be achieved by the use of an effective and affordable tracking system which yields acceptable accuracy and reliability and opens the potential for the system to be further developed for other purposes. These alternative uses could be the control of sunlight into green buildings, control of dampers for building ventilation and cooling and Trombe wall air control. This study has investigated the potential of several passive and active methods to actuate a sun tracking system. A useful closed loop system, which uses low pressure hydraulics, was developed and tested. The prototype is detailed in the drawings, Appendix D. , Thesis (PhD) -- Faculty of Engineering, the Built Environment, and Technology, 2021

The aim of this study is to investigate and build on the current technology of PV tracking systems with the aim of specifying a simple control and actuation system which performs the tracking function. The eventual purpose of this thesis is to reliably produce more energy from solar photovoltaic installations than similar installations using fixed panels. This would be achieved by the use of an effective and affordable tracking system which yields acceptable accuracy and reliability and opens the potential for the system to be further developed for other purposes. These alternative uses could be the control of sunlight into green buildings, control of dampers for building ventilation and cooling and Trombe wall air control. This study has investigated the potential of several passive and active methods to actuate a sun tracking system. A useful closed loop system, which uses low pressure hydraulics, was developed and tested. The prototype is detailed in the drawings, Appendix D. , Thesis (PhD) -- Faculty of Engineering, the Built Environment, and Technology, 2021

- Description: The study investigated how Batho Pele Principles can enhance professionalism in the Eastern Cape Provincial Legislature. The New Public Management approach (NPM) was used to explore how professionalism can be promoted through the implementation of the Batho Pele Principles. The study adopted a qualitative research method by means of which secondary information was obtained from various sources to explore ways and means of enhancing professionalism through the implementation of Batho Pele Principles. This study discussed factors promoting the implementation of the Batho Pele Principles and revealed various factors that can inhibit the implementation of the Batho Pele Principles. The study also discussed the importance of codes of conduct and ethics in promoting professionalism as well as the strategies used to implement the Batho Pele Principles in the Eastern Cape Provincial Legislature. The findings of the study revealed that professionalism can be enhanced through the implementation of Batho Pele Principles. For this to be successful in the Eastern Cape Provincial Legislature, the Batho Pele Principles should be implemented in conjunction with codes of conduct and ethics. , Thesis (MPA) -- Faculty of Humanities, 2021

- Description: The purpose of this study was to establish the extent to which the provision of social housing can be enhanced through public-private partnerships (PPPs) in the Buffalo City Municipality. A total quality management approach was used as a foundation to understand the application of PPPs in social housing delivery in the Buffalo City Municipality. The study was desktop research to understand the role of PPPs in the provision of social housing. The findings of the study revealed that PPPs provide additional capital for social housing development. The study highlighted that PPPs play a crucial role in providing alternative management and implementation skills as well as offering greater efficiency in the utilisation of financial resources in the delivery of social housing. The findings of the study further revealed that PPPs accelerate social housing delivery through the provision of additional sources of finance where the government is unable to increase public debt to meet investment needs. The study also identified a plethora of constraints that can hinder the adoption of PPP initiatives in social housing delivery. These include capacity constraints, financial constraints, lack of access to land and an unfavourable policy environment. Subsequently, the study advanced a set of recommendations in this regard that includes the creation of transparent and competitive procurement processes, government support in terms of financial incentives, review of the regulatory framework to improve access to land and the regulation of financial services institutions for access to affordable housing credit. , Thesis (MA) -- Faculty of Humanities, Department of Public Management and Leadership , 2021

- Description: Physical Education (PE) is vital for the holistic development of Foundation Phase learners. Foundation Phase teachers working in low resource contexts, however, being generalists rather than specialists, struggle to teach PE effectively, even when supplied with programmes by external experts. I was interested in finding out why, and what could be done to help them integrate Fundamental Movement Skills (FMS) into their teaching, to benefit their learners. I proceeded from the hypothesis that teachers should play an active part in their own development, otherwise any Continual Professional Teacher Development (CPTD) would not bring about the change desired. I argued that if CPTD training and support is embedded within their context and based on teaching philosophies that foster teacher transformation, empowerment, and advocacy, then teachers might be more likely to commit to teaching PE. My aim in this study was thus to develop a collaborative process of CPTD with Foundation Phase teachers in low resource schools to enrich their pedagogical content knowledge (PCK) of PE and FMS within their contexts of social disadvantage. I initially adopted a qualitative design, but during this study, I realised that a more participatory approach was needed. I therefore present my study in two phases In Phase One, I answered the question: What are Foundation Phase teachers’ experiences of implementing PE in low resource schools? I did so to inform the design of an appropriately suited CPTD model for Phase Two of this study. I used a qualitative research design situated within the interpretive paradigm. I purposively sampled 24 Foundation Phase teachers to partake in semi-structured interviews. Thematic analysis revealed three broad themes, namely, personal, and systemic barriers to PE, as well as positive responses to challenges. The overlap between themes was significant, highlighting the complexity of teachers’ experiences and perceptions of PE. Teachers’ positive responses emphasised that they possess the creativity and advocacy to overcome challenges posed and necessitated that I adopt a participatory design to work with teachers to develop a collaborative form of CPTD. Phase Two of this study was guided by the questions set by the participating teachers. Ten Foundation Phase teachers from two schools volunteered to be part of the study. In Cycle One they asked: What do we need to learn to be able to effectively implement PE? The findings of Cycle One led them to ask the following question in Cycle Two: How can we improve our confidence to teach PE within our school contexts? Participants did so through collaboratively creating PE lessons which they then implemented and evaluated. The findings of Phase Two highlighted how Foundation Phase teachers can be guided to empower themselves to overcome the barriers to teaching PE that they face in their low resource schools. Based on teachers’ CPTD experiences, I then addressed the third question of this study: What CPTD guidelines can be generated to enable Foundation Phase teachers to improve on and to implement their PCK of PE and FMS at low resource schools? Five CPTD guidelines aimed at collaborative and transformative PE-based CPTD focused on whole school transformation were identified. I provide a graphic depiction of the CPTD guidelines that explains how it can be operationalised. These CPTD guidelines and process model provide valuable knowledge to inform CPTD policy and practice of PE in the Foundation Phase in low resource schools. , Thesis (PhD) -- Faculty of Health Sciences, 2021
