- Description: The study focused on the evaluation of the integrated management system (IQMS) at selected schools within the Queenstown Education District. A quantitative research method was used for the study and questionnaires were used as a research tool to collect data. The respondents were members of the school management teams (SMT) which comprised the principals, deputy principals, heads of departments, senior educators and educators. These are key role-players in the management and implementation of IQMS. The rationale was to obtain pertinent information which would address the research questions and objectives of the study. The primary objective of the study as outlined above was to evaluate the impact of IQMS implementation in the Queenstown district with specific reference to the Lukhanji Circuit, on the performance of the high schools selected. It was envisaged that the results of the study would contribute towards developing measures to ensure that IQMS implementation achieves the desired objectives. The research questions were: To what extent can IQMS implementation be used as a tool to measure and improve teaching and learning? What measures have been put in place by the district to support and build capacity of the educators to perform? What factors hinder the effective IQMS implementation? The key findings of the study reveal that IQMS as a tool to improve teaching and learning had the overwhelming support of the majority of the respondents. However, a reasonable percentage of the respondents were of the view that IQMS constituted an administrative burden to educators. There are educators who displayed a negative attitude towards the implementation of IQMS. The respondents also felt that the district office needs to provide more support for IQMS implementation so that its objectives can be fully realised. The study makes clear recommendations such as the de-linking of IQMS from salaries and pay progression, provision of more support by the district, to make IQMS more user-friendly to educators and additional budget and teacher training to enhance educators’ professional development.

- Description: The performance management and development system (PMDS) is a tool that is used by government to measure the performance of individuals in the organisation. PMDS was developmental in its nature in identifying the development of employees and training in case of poor performance. The main aim of the PMDS is to motivate officials in the organisation by rewarding a performance bonus at the end of the financial year. There are challenges that affect the PMDS: officials felt that the system did not motivate them; it is perceived as a 14th cheque and some of them felt the system should be terminated. The main aim of the study is to evaluate the performance management and development system at the Department of Safety and Liaison in the Eastern Cape. Quantitative and qualitative data was collected through questionnaires and interviews. Questionnaires were distributed to officials from levels 1 - 8 and interviews were conducted with assistant managers, managers and senior managers. Descriptive statistics were used to analyse the questionnaires and transcriptions were used to interpret the interviews. The results of the study reflect that most officials in the Department are young and new to the public service. The findings show that the employees of the Department are average in their performance and the Department perceives that the PMDS is not used to identify poor performance and training. The system is not implemented effectively and efficiently. Based on the findings and recommendations made to management to facilitate the training on PMDS and also to allow the processes and procedures to be more efficient. Furthermore allowing performance from all staff to achieve the core objectives of the department.

- Description: Adaptive co-management (ACM), one of the most prominent management approaches to emerge in the recent years, combines iterative learning, flexibility, and adaptation promoted by adaptive management with the principles of nurturing diversity and fostering collaboration among different partners that underpin co-management philosophy. ACM has been proposed as an approach to address the deficiencies of centralized management in ensuring sustainability of social-ecological systems (SESs) in face of future uncertainties. This thesis aims to evaluate the readiness of resource users (the Waodani) as well as external actors (the Ecuadorian State and NGOs) for future implementation of ACM and thus enhancing the long-term social-ecological sustainability of the Waodani SES located in the Yasuni Biosphere Reserve in the Ecuadorian Amazon. Qualitative data obtained by means of focus groups with the Waodani and individual interviews with external actors and Waodani leaders revealed different levels of readiness for ACM. Firstly, in the case of the Waodani, the insufficient fulfillment of some conditions required for successful ACM as well as intercommunity differences in regards to these conditions can complicate the implementation of ACM, unless sufficient external assistance is offered to the SES. The analysis of NGOs demonstrated, on the other hand, a relative readiness for ACM, providing that such aspects as sufficient funding, long-term commitment to collaboration, and inter-institutional linkages are strengthened. The study also found that the Ecuadorian government’s potential to contribute to ACM is hindered by the lack of readiness to work with the indigenous society as well as by funding and communication challenges. Furthermore, the resource based economy supported by the State limits the scope of innovation and adaptation. Still, as in the case of other actors, overcoming the challenges and transitioning towards adaptive governance and thus ACM could be possible in the long-term, if recent legal and political changes are truly implemented.

- Description: The investigation of this study focused on the ability of provincial government departments in South Africa to spend allocated revenues on activities adequately, with a direct bearing on social and economic development. The research presents an analysis of two selected Eastern Cape Provincial Government departments’ expenditure for a three-year timeframe (the fiscal years from 2009–2012), with a focus on the oversight role played by the Provincial Planning and Treasury department in instilling fiscal discipline in the provinces, and the potentially detrimental effect of under-spending on provincial service delivery. Among other things mentioned and discussed are, firstly, the fiscal policy; secondly, the funding of provincial departments; thirdly, the role and responsibilities of the Provincial Planning and Treasury department. The study adopted a qualitative methodology which focussed on the perspective of the insider who has experienced first-hand the activities or procedures under scrutiny in the selected provincial departments. Further, the qualitative researcher believed that first-hand experience provides the most meaningful data. In support of this, the respondents were asked twenty-two questions, the first five of which were based on the need to understand their personal particulars. A semi-structured questionnaire was distributed to 43 officials and 22 of those questionnaires were returned.

- Description: The traditional mandate of local government is to deliver sustainable services to communities. The evolution of local government has since put more emphasis on evidence based planning in the form of IDP and sound financial management. The relationship between the IDP and Budget is that, a) the IDP contains community needs, objectives and strategies on how these will be responded or dealt with by the municipality, and b) the budget is the financial plan to execute strategies that need to be employed. The purpose of the study was to examine challenges in integrated development plan and the budget alignment of Amathole District Municipality. The study moved from the premise that municipalities are different and ADM has been in the fore front in terms of producing IDP and Budget. The study therefore is based on the assumption that the Amathole District Municipality has challenges in the IDP and Budget alignment. The study proposed to give a background of the scholarly literature of the IDP and Budget of local government. The empirical survey and research methodology used in the study is described and explained in-depths and followed by data collection in the form of the questionnaire. The research findings of the empirical survey are then analysed and reported in statistical form.

- Description: This thesis critically examines the nature and purpose of the MobiSAM partnership, in relation to its value as a model resonating with normative theories on the role of the media in South African democratic society. The MobiSAM project introduces a mobile polling application, designed for citizens to provide real-time, user-generated data on crucial municipal service delivery such as clean water in Grahamstown, Eastern Cape, South Africa. The project has partnered with the local community newspaper, Grocott's Mail, to broadcast this data, with the aim to facilitate citizen participation in public problem solving and support local government accountability in service delivery. Despite pervasive poverty in areas such as the Eastern Cape, mobile penetration in South Africa is near universal. The MobiSAM partnership is an ongoing effort to forge new links between social accountability monitors, new media, traditional media, citizens and local government around public issues in Grahamstown, in line with the development objectives of the post-apartheid South African state. The overall theoretical framework for this thesis is taken from Christians, Glasser, McQuail, Nordenstreng and White's Normative Theories of the Media, which provides an analysis of four roles of the media in a democratic society, that is: the monitorial, the facilitative, the radical and the collaborative roles. Within each of these roles, the stated journalistic approach is explored, that is investigative journalism, public journalism, radical journalism and development journalism. Public journalism is focused on as having the most resonance with the goals of the MobiSAM partnership. The chosen research design is a critical realist case study with the selected methods of thematic document analysis and, primarily, in-depth interviews with key project participants. The research goals were to analyse this primary data against the normative theory on the role of the media in a democratic society, and the 'real world' constraints posed by the project’s specific political and socioeconomic context. The findings conclude by offering certain recommendations and areas for further research, such as the central importance of a dedicated municipal reporter for covering complex public issues. This critical realist case study, drawing on qualitative interviews with both the accountability monitors and the media practitioners, interrogates the philosophical understandings on the role of the media in this new project, towards an empirical model for advancing substantive socio-economic change through media in South Africa.

- Description: At an international level, demands for accountability in respect of the quality of teaching and learning in higher education are increasing. This is also the case in South Africa. The response to these demands has taken the form of the introduction of quality assurance systems to higher education. In South Africa, a formal national external quality assurance was introduced to the higher education system in 2001 as a result of the establishment of the Higher Education Quality Committee. The Higher Education Quality Committee is a standing committee of the South African Council on Higher Education. Like other quality assurance agencies across the world, the Higher Education Quality Committee has the responsibility for i) auditing institutions of higher education and ii) accrediting learning programmes. The first cycle of institutional audits ran from 2004 until 2011. As quality assurance was introduced to the higher education system and the first cycle of institutional audits began, universities in South Africa developed policies and procedures intended to assure quality in three areas of their core functioning: research, teaching and learning and community engagement. The University of Venda, which is the focus of the study on which this thesis is based, was no exception. As a practitioner in the Centre for Higher Education Teaching and Learning at The University of Venda, it was my observation that the policies and procedures intended to assure quality in teaching and learning were not always implemented by academic staff members. This was in spite of poor student performance data which raised questions about the quality of the teaching and learning processes in place. The study underpinning this thesis was designed to explore this phenomenon. More specifically, it aimed to identify the conditions enabling and constraining the implementation of policies and procedures in two Schools in the University: the School of Health Sciences and the School of Human and Social Sciences. In order to explore these conditions, I adopted Roy Bhaskar’s Critical Realism as an under-labouring philosophy for the study. Critical realism posits a view of reality comprising three strata, none of which can be reducible to the other. The first of these strata is termed the level of the Empirical and consists of the experiences and observations which become apparent to us through the senses. The second layer, the Actual, consists of events from which these experiences and observations emerge. Underpinning both of these layers is a further layer, the Real, which is not accessible by empirical means and which consists of structures and mechanisms which generate both events at the level of the Actual and experiences and observation at the level of the Empirical. The design of my study sought to reach this deepest layer of reality to identify these mechanisms. Bhaskar’s critical realism is philosophy which needs to be operationalized using substantive, or explanatory, theory. For this purpose, I drew on Margaret Archer’s social realism. The design on my study drew on case study methodology and involved in-depth interviews with members of the two Schools which each formed cases within the more overarching case of the University itself. In addition to these interviews, I analysed a range of institutional documents related to the assurance of quality in teaching and learning. The exploration of enabling and constraining conditions at the level of the Real allow me to make a series of recommendations in the final Chapter of my thesis intended to enhance the quality assurance system introduced to the University.

- Description: This qualitative study focuses on business level strategy adopted by Twizza to compete in the bottom of the pyramid market in the Eastern Cape, South Africa. Twizza enjoyed huge success between the years 2010 - 2014 as a medium to large sized manufacturer of carbonated soft drinks in the Eastern Cape. In light of this, the current study seeks to answer the following: What business level strategy did top management at Twizza adopt to compete and grow in the BoP market in the Eastern Cape, South Africa? The study takes the form of a case study to explore and understand the patterns of decisions adopted by Twizza’s top management in competing at the bottom of the pyramid. As such, the main objective of the study was to identify the business level strategy adopted by Twizza which enabled their superior performance within the BoP market. The study adopts Porter`s typology to explore business level strategy. Stratified, purposive sampling was used to identify 4 top managers as participants in this study. A total of 7, semi-structured, interviews were used to collect critical incidents from top management of Twizza. This was the primary data used in this study. This type of data was combined with relevant information which was gathered via published press articles and on-line commentary. The study found that central to Twizza’s business strategy were four pillars, namely, strict control and management of manufacturing costs, product quality equal to that of market leaders, the ability of the organisation to manufacture its own raw materials and ability to ensure product availability to the market to the market. These findings reveal that Twizza employed a hybrid strategy, anchored by cost leadership. Thus, Twizza incorporated elements of differentiation and best value strategies to offer its customers affordable quality.

- Description: Approximately sixty percent of Africans depend on rainfed agriculture for their livelihoods. South Africa is evidenced to be susceptible to inclement climate which impacts on rural livelihoods as well as on farming systems. While South Africa is considered to be food sufficient, it is estimated that approximately 35percent of the population is vulnerable to food insecurity. Therefore with the application of surveys and interviews this study investigates the factors influencing household, subsistence and small-scale farmer perceptions of vulnerability to climate variability as well as the determinants of adaptive capacity. A sample of 308 households is surveyed and four focus group discussions are administered in Ngqushwa Local Municipality as a case study. Furthermore, the study also focuses on the biophysical changes or factors (scientific analysis of the prevailing climatic regimes–rainfall trends); the interrogation of the impact of food systems on both food prices as well as its implications on food sovereignty. The study also interrogates the relationship between crop yield and rainfall data over a 30-year period. Therefore the study adopts a mixed method approach to ensure triangulation. The study finds that rural communities are able to perceive climate variability and its related changes as well as its negative impact on crop production, food access and availability. The perceived rainfall trends also corroborate this Pearson product-moment correlation coefficient reveals that there is a strong correlation between crop yields and rainfall (r = 0.69). Meteorological analyses also show that the rainfall trend has been significantly variable over 112 years (1900 - 2011) with several dry spells threatening the subsistence and small-scale farmers’ sustainable livelihoods. The food systems pose threats to food safety, food security and historical food sovereignty for the rural community of Ngqushwa Local Municipality. Adaptive capacity is greatly impaired by the lack of co-ordination of adaptation strategies, which communally benefit the majority of the farming respondents in the study area. Therefore vulnerability to climate variability impacts on the ability of the respondents to achieve food security. The study also finds that there is perceived competition between the farmers and wild life for the natural resources. The respondents’ perception is that climate variability and change is responsible for such competition. The study recommends that the national, provincial and local governments must foster a new food production model that is not based on the agro-business model and its attendant technologies but on one that is based on robust agro-ecological farming techniques which enhance adaptive capacity; which foster food safety; which promote food sovereignty; and which reduce vulnerability in a sustainable manner. Given the extent of climate variability in the study area the restoration of the NLM weather station infrastructure can also aid the farmers in taking advantage of a robust early warning system for better estimation of climate trends which enhance crop production.

- Description: The rise of International Non-Governmental Organisations (INGOS) in the post-Cold War era in Africa exerted pressure on conflict resolution mechanisms as governments responded to perceived and real pressure from external, mainly Western countries. INGOs are well resourced and conduct ‘humanitarian’ and other work funded by donors. The issue of funding is critical to control and legitimacy. It is also tied to achievement of intended goals. The study explores the relationships and in some cases conflict between Western NGOs in Zimbabwe and the government during the period when the latter was experiencing diplomatic estrangement with Western countries. The qualitative study seeks to establish whether INGO operations were influenced by political relations. The researcher interviewed twenty experts in NGO and governmental operations using an interview guide. Data was collected and entered into Nvivo software where it was thematically analysed. The major findings of the study are that the political strand is the main relational context that determined the relationship between the government and INGOs. INGOs were viewed as active conflict drivers mostly due to the bias towards certain political parties and being conduits of Western initiatives. Local conflict resolution mechanisms were also established to be inadequate. The study recommends that the government of Zimbabwe needs to work on maladministration and resolve differences with Western countries. Local NGOs and INGOs should not meddle in politics in order to have a trustworthy relationship with government while donor funds are more appreciated when channelled through governments.

- Description: Mindfulness research is growing considerably, though there is very little research in the area of HIV and mindfulness. This study explored and described the experience of a sample of HIV positive people, before and after an 8 week Mindfulness Based Stress Reduction (MBSR) programme, to ascertain whether mindfulness can positively impact the CD4 count of the participants, with the consequent improvement to their immune systems. The incidence of depression, anxiety and stress levels were also explored. The research sample consisted of 17 participants recruited from a local hospital clinic. Purposive sampling was used to source participants. The mixed method approach of data gathering was made up of a pre-test post-test battery of questionnaires and blood tests. Mindfulness levels were assessed with the Five Facet Mindfulness Questionnaire (FFMQ) and Mindfulness Attention Awareness Scale (MAAS) at 3 intervals, while depression, anxiety and stress were assessed by means of the Depression Anxiety Stress Scale (DASS-21). Key findings included the following: the drop out rate for this population group was large, mindfulness practices do not always have a positive effect on immune functioning when there are other confounding variables at play, all participants reported they benefited from the 8 week MBSR course, though their results did not always indicate this. In conclusion it is proposed that mindfulness is potentially beneficial.

- Description: The purpose of this study was to explore the extent to which a School Nutrition Programme can catalyse community-based environmental learning and promote food security in the school and the community. This is an interpretive case study of a junior secondary school in the rural Eastern Cape province of South Africa. The school is located in an area characterised by high levels of poverty and under-nutrition. The school’s food garden, a central focus of this study, contributes to the School Nutrition Programme, which falls under the National School Nutrition Programme (NSNP). The aim of the NSNP is to alleviate poverty in public schools. This case study was conducted by means of questionnaires, semi-structured interviews, and document analysis and field observations. The data set was analysed, firstly, to ascertain if the School Nutrition Programme functions as a community of practise (Wenger, 1998). Thereafter, the data set was analysed to identify the knowledge related to food security and environmental sustainability that is learned and shared in the School Nutrition Programme, and also how such learning took place. The study found that the School’s Nutrition Programme was indeed operating as a community of practice and that it created a platform for sharing explicit and tacit knowledge and skills related to food security and environmental sustainability. The case study also revealed the contextual and experience-based nature of knowledge related to food cultivation.

- Description: This paper reports findings on how Namibian secondary school Life Skills teachers are exercising their agency to teach or not to teach Sexuality and HIV and AIDS, a subject which is regarded as sensitive and has been surrounded by secrecy and has issues which are cloaked by silence and taboos. The aim of the study was to explore the structural and cultural factors that shape the responses and experiences of Life Skills teachers in teaching sexuality and HIV and AIDS. The study was conducted through observations and interviews with four full-time Life Skills teachers. Document analysis was carried out throughout the study in which lesson plans, portfolios, assessment forms, Life Skills syllabuses, schemes of works, national curriculum documents and subject policy on HIV and AIDS were analysed. The data were analysed by identifying categories, codes and themes using the analytic dualism framework, and the literature review was used to summarise the findings. The study revealed that all teachers operate in an environment that consists of the National structures such as high teacher: learner ratio in their classrooms that they have to teach Life Skills and do day to day counselling, a lack of teaching and learning support material that they should use to scaffold the learning of sexuality and HIV and AIDS, and little time allocated to Life Skills teaching. The same study also revealed that the teaching of Life Skills is hampered by the cultural structures which emerged from teachers’ discourses as evidenced from the data which shows that cultural properties have powers that condition teachers in teaching sexuality and HIV and AIDS. This included learners’ silence in sex-related discussion versus teachers’ position; discourses on the importance of full-time Life Skills teachers in school; comfort in teaching selected topics in Life Skills; Life Skills teachers’ perceptions on parents’ feelings on teaching sexuality and HIV and AIDS in schools, and perceptions on the Life Skills teachers’ position and teaching sexuality and sex education. While the findings revealed that teachers are conditioned by the structural and cultural conditions that acted as constraints to teaching sexuality and HIV and AIDS, the observations revealed agency on their part. The study finding depicts instances where teachers acted in agreement or in contravention of the structural and cultural pressures or conditions in their environments.

- Description: In trying to prove that derivations of type I AW -algebras are inner, I. Kaplansky introduced and developed the basics of the concept of Hilbert C- modules. He sought to generalize the idea of a Hilbert space by replacing the field C of all complex numbers with a general (commutative and unital) C-algebra. Twenty years later, the concept was broadened and expanded to non-commutative C-algebras by W. L. Paschke and M. A. Rieffel in their papers on inner product modules over B-algebras and induced representations of C-algebras, respectively. Since then, the theory of Hilbert C-modules has grown rapidly. It was used by G. G. Kasparov as the framework for his bivariant K-theory. More recently, Hilbert C-modules have formed the technical basis for the C*-algebraic approach to quantum group theory. The aim of this dissertation is to provide as detailed an account as possible of the theory of Hilbert C-modules, as given in a book of E. C. Lance, up to and including the KSGNS construction. The KSGNS construction, named after Kasparov, Stinespring, Gelfand, Naimark and Segal, is a generalization to Hilbert C-modules of the familiar GNS construction for C-algebras. The result by Kaplansky that all derivations of a type I AW-algebra are inner is given as an application in the final chapter of the dissertation.

- Description: The primary objective of this study was to evaluate the effectiveness of the Souns-for-Literacy program in selected Knysna and Plettenberg Bay pre-schools. This included investigating if there were significant benefits for its recipients and recommending improvements that could be made to the program, particularly in adapting it to fit the South African context. The program claims to build letter-sound associations. In response to evidence gained in the biannual surveys done by KET, it was decided that the program warranted a more formal evaluation. It was later agreed that the evaluation should i) critically examine claims about the effectiveness of the program; ii) analyse the relative value of factors contributing to its effectiveness, such as teachers, implementation practices and the program’s material and methodology, then iii) recommend improvements that cauld be made to the program. The evaluation should also identify insights gained in developing reading skills in pre-school children, specifically in South Africa’s multicultural and multilingual contexts. The total number of schools investigated was 25 (21 pre-schools and 4 primary schools for follow-up purposes). The data collection was primarily through i) interviews with program personnel (mentors, facilitators, teachers and volunteers), ii) observations of the children interacting with the equipment of the program as well as iii) individual, informal and age-appropriate testing of letter-sound association knowledge at the end of the academic year. The findings revealed that: i) the program’s materials and methodology showed ‘highly significant’ benefits to most of its beneficiaries; ii) KET’s support system (including mentors, facilitators and volunteers) was particularly valuable in contributing to the program’s effectiveness; iii) certain adaptations to the sequence of symbol presentation for each language would benefit the children’s word-building capacity; iv)the emergent literacy skill of learning letter-sound knowledge should gain more focus during this pre-school stage.

- Description: Cheminformatic approaches have been employed to optimize the bis-coumarin scaffold identified by Onywera et al. (2012) as a potential hit against the protease HIV-1 protein. The Open Babel library of commands was used to access functions that were incorporated into a markov chain recursive program that generated 17750 analogues of the bis-coumarin scaffold. The Morita-Baylis-Hillman accessible heterocycles were used to introduce structural diversity within the virtual library. In silico high through-put virtual screening using AutoDock Vina was used to rapidly screen the virtual library ligand set against 61 protease models built by Onywera et al. (2012). CheS-Mapper computed a principle component analysis of the compounds based on 13 selected chemical descriptors. The compounds were plotted against the principle component analysis within a 3 dimensional chemical space in order to inspect the diversity of the virtual library. The physicochemical properties and binding affinities were used to identify the top 3 performing ligands. ACPYPE was used to inspect the constitutional properties and eliminated virtual compounds that possessed open valences. Chromene based ligand 805 and ligand 6610 were selected as the lead candidates from the high-throughput virtual screening procedure we employed. Molecular dynamic simulations of the lead candidates performed for 5 ns allowed the stability of the ligand protein complexes with protease model 305152. The free energy of binding of the leads with protease model 305152 was computed over the first 50 ps of simulation using the molecular mechanics Poisson-Boltzmann method. Analysis structural features and energy profiles from molecular dynamic simulations of the protein–ligand complexes indicated that although ligand 805 had a weaker binding affinity in terms of docking, it outperformed ligand 6610 in terms of complex stability and free energy of binding. Medicinal chemistry approaches will be used to optimize the lead candidates before their analogues will be synthesized and assayed for in vivo protease activity.

- Description: Since the exhaust emissions legislation for motor vehicles with combustion engines is complicating the manufacturing of environmental yet powerful engines more than ever, automobile manufacturers have approached this challenge by means of downsizing, hybridization of combustion and electric engines and variable valve opening times. In these cases conventional, mechanical valve trains are still used. The subject of this master thesis is the development of a mechatronic control unit as replacement for the camshaft driven valve train of common combustion engines. The system’s aim is a contribution to the progression of the development of modern combustion engines satisfying current demands in terms of economy and efficiency. The developed system is based on the “Full Variable Valve Train” project, founded at the “Institute of Vehicle Construction Wolfsburg” at the “Ostfalia University of Applied Sciences”. An indirectly controlled high speed servo valve that is actuated by a piezoelectric actuator and pressurized hydraulic fluid is being developed. The overall aim is to obtain advantages from a control engineering perspective, being able to reduce the size of the used piezo actuator and hence solve the packaging and regulation issues of the overall system. After manufacturing and improvement activities, a system could be developed that allows a variable control of the engine valve movement. The best results are achieved using a rectangular function for the engine valve actuator. The system allows engine valve operation independent from the crankshaft position and shows the potential to generate higher engine torque and power output while decreasing fuel consumption and emissions at the same time.

- Description: The study focused on strategies for improving reading comprehension skills at Grade 9 level through story writing in one secondary school in the East London Education District. Vygotskian theory formed the theoretical framework for this study, aligned with language theories as relevant literature for this particular research study. Data was generated from 15 Grade 9 learners who were selected from 3 Grade 9 classes using convenience sampling, comprising of five learners from Grade 9(a) intervention group, five learners from Grade 9(b) and five learners from Grade 9(c) non-intervention group who were selected for this study with the inclusion of two Grade 9 teachers and one Grade 8 teacher. Involvement of the grade 8 teacher is relevant to determine the voice from a Grade 8 teacher as an informed voice, which filtered into understanding how and why Grade 9 learners are unable to read and write with understanding in their present grade. The teachers were given three questions for semi-structured interviews. All the learners were given a specific activity as a pre-assessment without intervention strategy. The Grade 9(a), which is the intervention class, used story writing as an intervention strategy where they began a two week study using intensive intervention strategies, amounting to a total of 18 weeks study from pre-assessment to post-assessment. At the conclusion of the study the selected learners undertook a post-assessment using the same specific activity as in the pre-assessment. Subsequently, these selected Grade 9 learners’ reading comprehension pre-assessment and post-assessment was analysed. Five of the grade 9(a) learners demonstrated significant improvement in the intervention activities they were given. Grade 9(b) and Grade 9(c) showed difficulty in the post-assessment as they were the non-intervention group. It was concluded that Grade 9(a) learners performed better in the post-assessment. This could be attributed to the use of story writing as an intervention strategy to improve their English reading and reading comprehension skills. Keywords: intervention, reading, comprehension.
