- Description: This study investigated how selected grade 11 mathematics learners used smartphones with the MathCityMap application to learn trigonometry outdoors for conceptual understanding. The aim of this research project was to explore outdoor mathematics learning for conceptual understanding using smartphones. This case study of grade 11 mathematics learners in Lejweleputswa District in the Free State Province, was informed by the Realistic Mathematics Education theory. The study is grounded within an interpretive paradigm and used the explanatory sequential mixed-method design. Forty-two grade 11 mathematics learners participated in the survey and from these 12 were purposively selected to participate in walking the mathematics trails and interviews. The findings revealed that, while the grade 11 mathematics learners acknowledged the significance and value of using smartphones for learning mathematics, they were prohibited from carrying or using smartphones on the school premises, as part of the school code of conduct. The preferred use of smartphones for learning mathematics was understandable, as the survey was conducted at a time when the COVID-19 pandemic and associated restrictions were still in place. The survey unearthed that among applications for learning mathematics, the MathCityMap application was not known by the learners who participated in the survey. Mathematics trails observations indicated that outdoor tasks were a source of mathematical concepts or formal mathematical knowledge, and enabled learners to reinvent mathematical ideas and concepts with adult guidance. Learners were able to make use of appropriate mathematical models and connections. The mathematics trails ignited robust discussions among learners, and prompted learners to draw from prior knowledge, and recognise and identify suitable mathematical models and shapes from the real-world objects. Learners were able to use multiple representations, make necessary mathematical links, and use their prior knowledge to enhance their trigonometry conceptual understanding. This study concluded that using smartphones with the MathCityMap application could enhance conceptual understanding of trigonometry. The implications for teachers are that learners should be exposed to outdoor mathematics learning using smartphones with the MathCityMap application to improve their conceptual understanding. It is hoped that the results of this study can be used by various stakeholders, who include, inter alia, mathematics subject advisors and teacher training institutions, to enhance learners’ conceptual understanding of mathematics. , Thesis (MEd) -- Faculty of Education, Secondary and Post School Education, 2024

- Description: Despite increased research interest in recent years in the metalinguistic skills underpinning reading in the Southern Bantu languages, little work has been done on the underlying microlinguistic layer. This refers to the actual mechanical underpinnings of linguistic skills; zooming in on micro-language structures so as to explicate our understanding of how reading works. One such microlinguistic phenomenon is the effect of orthographic neighbours on reading and writing. Research has found predominantly faciliatory neighbourhood effects for English word reading (Andrews, 1997; Siakaluk, Sears & Lupker, 2002; Yarkoni, Balota & Yap, 2008). Specifically, words with more orthographic neighbours have faster response times in lexical decision and naming tasks. However, in languages such as Spanish and French, inhibitory neighbourhood effects are reported (Grainger & Jacobs, 1996; Carreiras, Perea & Grainger, 1997). These findings highlight the language-specific nature of orthographic neighbourhood effects (Andrews, 1997), and the necessity for language- specific investigations of these effects. This thesis investigates the linguistic properties of orthographic neighbours in isiXhosa, thereby developing a database of orthographic neighbourhoods in isiXhosa. Further, this research explores the interaction between orthographic neighbourhood density and neighbourhood frequency with three literacy skills: lexical decision response time, word reading accuracy, and spelling accuracy. Data were collected from 97 isiXhosa grade three learners from five schools in KwaNobuhle Township in the Eastern Cape. A corpus of 170 000 tokens of isiXhosa words (Rees & Randera, 2017) was used to compile a database of orthographic neighbourhoods for 30 real, and 30 pseudowords which ranged in orthographic neighbourhood density and neighbourhood frequency, whilst controlling for word length and word frequency. Using this database, lexical decision, word reading, and spelling tasks were designed and administered to the participants. Findings indicate a significant inhibitory effect of orthographic neighbourhood frequency on spelling accuracy. Words with high neighbourhood frequencies are more likely to be spelt incorrectly. There was no observed effect of orthographic neighbourhoods on lexical decision response time and word reading accuracy. These results are interpreted within connectionist and search models of orthographic processing. Specifically, the findings indicate a partial reliance on lexical processing strategies when spelling. That is, orthographic neighbours compete for lexical access when spelling. Education practitioners may wish to present learners with lists of orthographic neighbours when introducing novel words so as to make explicit the fine grain differences between words in the language. This also means that future research will need to develop a larger repository of orthographic neighbours in isiXhosa that can be made available for pedagogical purposes. , Thesis (MA) -- Faculty of Humanities, Linguistics and Applied Language Studies, 2023

- 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: 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
