- Description: This study locates the Blackboard Learning Management System as a Technology Enhanced Learning tool within the bounds of the discipline of eLearning and aimed to interrogate the use of Blackboard for the purposes of teaching, learning and assessment in large classes. It is evident from the literature reviewed that changes in both Higher Education in the South Africa with regards to policy and legislation in addition to international shifts towards increased access and participation in a fast paced, ever-evolving knowledge-based economy, providing the context for this work. The theoretical framework for this study is not unidimensional due to the fact that the educational field of eLearning as an area of specialisation draws on a multitude of theories in terms of their utility value for instructional design of courses utilising Information and Communications Technology as a mode of delivery. This study was conducted within the bounds of an interpretivist paradigm as the researcher sought to focus on the use of Blackboard and the experiences of the lecturers and students involved in the implementation thereof. The research design for this study took the form of a case study and a multiple case method was employed. The researcher collected data through personal interviews conducted with participating lecturers, while student data was collected by means of a qualitative survey which was conducted through the Blackboard Learning Management System. The data was analyzed by means of a thematic analysis, consistent with the interpretive paradigm chosen for this study. The findings of this study revealed that Blackboard was utilised effectively in order to facilitate communication, access to course resources and promoted more efficient assessment processes. The implementation was however not without challenges many of which were systemic and focused on the lack of resources available to the students. The implications of using Blackboard for teaching and assessment of large classes include the use of the Learning Management System as part of a multimodal method of course delivery in an effort to reach the multitude of registered students both conceptually as well as electronically. The recommendations arising from this study include consideration on the part of the faculty for a unified approach in the use of Blackboard for communication as well as deployment of resources. Additionally, this study may form the foundation of further studies in this field, with a focus on the active engagement and training of lecturers in order to integrate traditional teaching methods with blended learning opportunities.

- Description: Research reports using global data show that the failure rates in introductory programming courses average about 32 percent. This study assessed the effect of elements of Guided Inquiry Learning (GIL) on enhancing academic performance of first year students in Introduction to Computer Programming course. As learners from schools join the university and enrol for different courses, they find the sudden transformation quite challenging. This makes it more challenging for first year university students, especially in difficult courses such as Introduction to Programming. As times change with advances in technology, the traditional ways of presenting information during teaching–learning interface may not address students’ needs. Lecturers and university stakeholders make efforts to address these challenges by proposing innovative teaching ways. One of the common approaches that have been used profitably in other science and engineering programmes is GIL. It is a form of inductive collaborative learning approach where students are presented with a challenge which challenges them to accomplish the desired learning outcomes in the process of responding to the posed challenge. The strategies in GIL include, among others, learning teams who participate in intra- and inter-learner interactions besides lecturer-learner interactions, linking theory and practical information cementing skills and problem solving strategies, scaffolding information, blended learning by integrating both traditional and technology-assisted learning, inquiry activities such as initiating investigations, gathering data, and critiquing evidence to come up with evidence-based solutions. The objective was to apply GIL to this module and observe if there were gains in students’ academic performance. This study was located in the pragmatic paradigm using action research design and a mixed method approach. The sample consisted offirst year students enrolled for Introduction to programming which was a year-long course (two semesters) at a South African university. The population consisted of the only 49 students who were registered for the module under focus. A group of 20 students were considered for the whole year in the GIL experiment. Although it would students were considered for the whole year in the GIL experiment. Although it would students were considered for the whole year in the GIL experiment. Although it would have been ideal to have experimental and control groups with same number of students, that was not possible in this study, because only 20 out of the 49 who were willing to be included in the experimental group. The present researcher employed willing to be included in the experimental group. The present researcher employed three of these GIL strategies in teaching the module Introduction to Programming to the experimental group while another colleague continued with traditional teaching in the control group. Care was taken to limit the insider outsider conflict. Both groups were assessed by the same assessment tools at the same times. Results from these assessments together with focus group interviews provided the core data for this study. Both quantitative and qualitative analyses were carried out on the data, statistical analysis (mainly, chi-Square and t-test) for the former and thematic analysis for the latter. Results indicated gains in the experimental group such as enhanced motivation, interaction, intra-group social cohesion, creativity and provided students the confidence to share knowledge and skills with their peers and keep everyone focused on the course contents. These gains are reflected in higher year marks and pass rates than those in the control group as the analysed data indicate. A study that will pilot the GIL framework in several universities with different teaching modes and large classes are recommended.

Evaluation of groundwater potential using neotectonics and geophysics in the context of post Karoo tectonic framework around Fort Beaufort and Smithfield, Eastern Cape, South Africa

- Description: Geological and geophysical methods were used to investigate the Karoo area extending from longitudes 25.50 E to 27.50 E and latitudes 300 S to 330 S in South Africa, particularly Fort Beaufort, Aliwal North, Venterstad and Smithfield. The geology of the area is dominated by the upper Beaufort Group (Adelaide Subgroup) with an extensive network of dolerite sills and dykes that intruded the sedimentary sequence. A relationship between neotectonics, post-Karoo tectonics, groundwater and lithology was investigated to locate suitable groundwater potential sites. Apart from studying the role of neotectonics and the post Karoo tectonics, this research aims at generating groundwater targets to alleviate water shortages mainly for farming and livestock, and prove that neotectonics is still active. Methodologies adopted for obtaining these results included a comprehensive literature review, thin section analysis, scanning electron microscopy, geophysical investigation (magnetic, gravity, and vertical electrical sounding), and the application of Geographical Information Systems (GIS) and remote sensing. Twenty samples were collected at various locations within the study area and were analyzed using the petrographic microscope while others were analyzed with the Scanning Electron Microscopic (SEM) combined with an Energy dispersive x-ray spectrometry. The results show that the rocks are fractured, porous and have variable mineralogy (presence of heavy minerals) within the rocks. The use of Geographical Information Systems (GIS) and remote sensing in geological surveys, especially hydrogeology, has gained momentum over the past few years. This research is no exception as ArcMap software was used to create a map of seismic epicentres of the Eastern Cape Province. From the map it can be observed that seismicity still occurs and thus leading to the notion of neotectonics being active. Lineaments were also automatically extracted using the ENVI 5.1 and Geomatica 2013 software. Lineaments are zones of weakness in the subsurface of the Earth and are very important in locating groundwater potential sites. Geophysical techniques are essential and highly accurate for groundwater studies. Gravity and magnetic techniques were applied on data which was supplied as grids. Analysis using Geosoft Oasis 8.3 revealed extensive lineaments and ring like patterns and these were inferred to be dolerite intrusions (sills and dykes). The morphology of the intrusions help in identifying possible groundwater potential zones and thus they should be investigated. Vertical electrical sounding (VES) technique using the Schlumberger array was carried out at three sites (Fort Beaufort fracture which is possibly related to Quaternary surface uplift of the Amatole-Swaziland axis, splay of the Fort Beaufort fracture and at a site which showed high groundwater potential) to explore subsurface layering. IP2win (lite), 1-D modelling software was used to model the apparent resistivity data to obtain the geoelectric parameters of the subsurface (thickness and resistivity). The VES results are consistent with fractured rocks that aid groundwater movement. The VES data for the three sites was further modelled by the RES2DINV software and this shows low resistivity values associated with loose, water saturated top sandy soil and higher resistivity values associated with sedimentary sequences and dolerite. Moreover, potential sites for citing wells are predicted to be between 79.5 and 128 m on the profile. Further neotectonic studies need to be done, especially on the quaternary sediments as they would have more neotectonic evidence. The use of geophysical techniques for groundwater search need to be intensified, with more emphasis being put to the sedimentary sequences bordered by dolerite intrusions and fractured zones.

- Description: Government promulgated the land rental policy starting in the year 2007. The policy required that A1 (market residual) and A2 (indigenous commercial) farmers pay rentals to the state. Since then, there has also been an emerging trend in which farmers have been renting in and out land, resulting in an informal market for land rentals. The study therefore assessed farmers’ perceptions of land rental policy and evaluated the possible association of this policy to farmers’ decision making on land rental markets as well as its implications on farmers’ efficiency and equity. The study was carried out in Mashonaland East Province of Zimbabwe, covering two districts, Goromonzi and Marondera. The focus was specifically on A1 and A2 farmers, as the rental policy was directed at these resettlement models only and much of the informal land rental markets were prevalent among these categories of farmers. Data collection utilised the survey approach. This was supported by key informant interviews and focus group discussions, with a final sample of 339 households selected using multi-stage sampling method. Survey data were transcribed on CsPro 6, and analysed using Stata, SPSS and Frontier 4.1. Results showed that about a third of household respondents was from Marondera and twothirds was from Goromonzi, while 79% and 21% was A1 and A2 farmers respectively. About 80% was male headed households and the remainder was female headed households. About half of the households were not participating in land rental markets while the other half was split almost equally between those renting-in and renting-out land. In general, A2 farmers were better in agricultural productivity than A1 farmers. It was concluded that farmers had a fairly good knowledge of the agricultural land rental policy enunciated in the Finance Bills. A1 farmers were more knowledgeable than A2 farmers, but no vii significant differences were observed between male and female headed households and farmers involved and not involved in land rental markets. Farmers’ attitudes in relation to policy were categorised as fair, with significant differences based on gender and land market participation. Practice scores showed a poor adherence to policy for all categories of farmers. Overall perceptions of farmers on rental policy was inferred as fair with significant differences existing between land rental market participants and non-participants (autarky). The results of a bivariate Tobit model results showed that the decision to rent-in land was significantly influenced by gender, household income, permanent labour, cultivated area, tenure certainty, irrigable land size and crop diversification. On the other hand, age, permanent labour, irrigable land size and crop diversification significantly influenced farmers’ decisions to rent-out land. The conclusion was that household characteristics, land endowments and transaction costs significantly influenced the decision to rent-in land while the former two were strong in influencing renting-out decisions. Results from the linearized Cobb Douglas model showed that economic efficiency for most farmers was above 50%. Farmers renting-out land under A1 were found to be the most economically efficient, followed by those who were renting-in and least efficient were farmers not participating in land rental markets, though the differences were marginal. For the A2 model, renting-in farmers were the most efficient, followed by those in autarky position, while renting-out farmers were the least. Overall, the most efficient farmers were those renting-in, followed by those renting-out while farmers in autarky were the least efficient. Overall efficiency was higher for A2 farmers than for A1 farmers. For farmers not participating in rental markets, the sources of inefficiency were crop type, crop area and labour. For farmers renting-in, it was proportion of irrigable land, size of irrigable land, crop type, crop area and viii labour, while inefficiency drivers for renting-out farmers were crop type and associated area. Equity analysis showed that participation in land rental markets reduced inequality for farmers in the two districts and male and female headed households. Inequality was increased among A1 farmers and remained unchanged among A2 farmers. Overall, the emerging position was that participation in land rental markets resulted in higher efficiency and reduced inequality in land holding among the sampled farmers. It is recommended that government should be consistent on land rental policy and bring into place effective administration of land rental policy. Government may also consider formal acceptance of land rental markets in light of the marginal efficiency and equity benefits shown in the study. However, formalizing land rental markets alone may not be a panacea to improved efficiency and needs to be supported by other productivity measures given the average efficiency values for farmers. Crop and livestock production based on compatibility with the natural regions and defined minimum size of land should be encouraged to improve efficiency

- Description: Neither the South African government, nor organised agriculture, nor the research community, has an accurate understanding of the role that the citrus sub-sector plays in the local economy of the main producing areas. There are in fact few studies in South Africa on the linkages between agriculture and other economic sectors at the local level. Through understanding the backward and forward linkages in the citrus sub-sector in Sundays River Valley, one of South Africa’s main citrus areas, it is possible to obtain a better understanding of how investment and expenditure in this sub-sector might influence other related subsectors. The main objective of the study is to assess and understand the citrus industry's contribution to the local economy of Sundays River Valley Local Municipality. This is done through the estimation of an input-output table which differentiates local from non-local economic linkages, and which also, given the labour intensity of the citrus subsector, is closed with respect to households, i.e. households are treated as an endogenous sector with interrelationships with the other sectors captured. The other sectors captured include agroprocessing, utilities, transport and retail. The input-out table, which is estimated based on primary surveys as well as secondary data, is thereafter used to perform input-output analysis on the basis of which the impact of different types of sectoral development are simulated. Results show that jobs can be created through expansion of area under citrus. In addition, more income to farm workers translates into higher income into the local retail sector. However, labour-saving technology could lead to job losses in both citrus and agroprocessing sectors.

- Description: It has long been identified that relative deprivation increases prejudice. Guimond and Dambrun (2002) demonstrated that relative gratification, as the opposite of relative deprivation, is also an important variable in predicting intergroup discrimination. Guimond and Dambrun (2002), further suggest that in order to prevent destructive conflicts between groups, such as intergroup discrimination, the goal of equality rather than economic improvements has to be kept in mind. The present paper will report three experiments which aimed to replicate Guimond and Dambrun’s (2002) findings on relative deprivation and relative gratification and which further aimed to test their proposal that equality would reduce prejudice. The results of the three experiments confirmed the predicted effects of relative deprivation and relative gratification on intergroup discrimination. However, the results did not confirm that equality reduces prejudice. Methodological and theoretical reasons for these results are provided and discussed in detail.

- Description: Discovery of cheap, nontoxic and readily available antiatherosclerotic drugs is an extraordinary challenge in this modern world. Atherosclerosis and cardiovascular diseases have been predicted to be the leading cause of death by the year 2030. Hence, this thesis was designed to search for plant (s) with anti-atherogenic properties, investigate its possible side effects and extrapolate its likely mechanism(s) of action. An ethnobotanical survey was employed in identification of locally important plants used for the management and treatment of cardiovascular diseases and its predisposing factors in Nkonkobe Municipality, Eastern Cape in South Africa. Information on the names of plants, their parts used and methods of preparation was collected through a questionnaire which was administered to herbalists, traditional healers and rural dwellers. The most frequently used plant (Rhizomes of Tulbaghia violacea Harv.) was investigated for toxicity using brine shrimp lethality (in vitro) and in vivo toxicity test (acute and subchronic) on rats to determine safety dosage. The in vitro antioxidant and free radical scavenging activity of the plant was investigated using models such as 1,1-diphenyl-2- picrylhydrazyl (DPPH), superoxide anions, hydrogen peroxide (H2O2), nitric oxide (NO), 2,2’- azinobis [3-ethylbenzothiazoline-6-sulfonic acid] diammonium salt (ABTS), lipid peroxidation inhibition and the ferric reducing agent. Phytochemical content and the effect of oral administration of fresh methanolic extract rhizomes of Tulbaghia violacea (250, 500 mg/kg. bwt/day) on Lipid peroxidation (TBARS), serum and tissue antioxidant enzymes in normal, hypercholesterolemic and diet induced atherogenic rats were also assessed. More so, the potential of the extract (250 and 500 mg/kg. bwt) to protect against atherogenic diet (4 percentage cholesterol 1 pecentage cholic acid and 0.5 percentage thiouracil) induced fatty streaks formation, dyslipidemia, oxidative stress and endothelial dysfunction was also investigated. Ethnobotanical study revealed that 19 plant species are used for the treatment of heart related diseases in the Municipality. 53 percentage of the plants mentioned were used for the management of chest pain, 47 percentage for high blood pressure, 42 percent for heart disease, 16 percentage for stroke and 11 percentage for the treatment of hypercholesterolemia. Tulbaghia violacea was repeatedly mentioned as the plant species used for the treatment of high blood pressure and predisposing factors in the study area. The brine shrimp cytotoxicity test revealed that fresh, dried methanolic extracts and essential oil of the T. violacea exhibited a high degree of cytotoxic activity with IC50 values of 18.18 (fresh) and 19.24 (dried) μg/ml. An IC50 value of 12. 59 μg/ml was obtained for the essential oil of the plant. The low cytotoxicity values obtained, suggested that rhizome of T. violacea may serve as a potential source of antimicrobial and anticancer agents. In vivo acute study of single oral administration of 5g/kg dose does not produce mortality or significant behavioral changes during 14 days observation. In the sub-chronic study, the extract (250, 500 mg/kg/bwt/ day) administered for a period of 28 days showed no mortality or morbidity. The weekly body and organ weight of the rats showed no significant differences between the control and the rats treated with the extract. The extract at all doses does not show any effect on of biomarkers of liver or renal damage. However, a significant decrease in the activity of ƔGT was observed in the extract treated groups. Hematological evaluation revealed that oral administration of fresh methanolic extracts of rhizomes of T. violacea does not cause anaemia or leucocytosis in the animals. Furthermore, histopathology results of the internal organs revealed no detectable inflammation. These results demonstrated that the rhizome extract of T. violacea was potentially safe for consumption orally even in chronic concentration. In vitro antioxidant evaluation showed that the essential oil, fresh and dried methanolic extracts exhibited potent antioxidant activities in a concentration dependent manner. Phytochemical investigation reveals that the fresh and the dry extract of RTV are rich in flavonoid, flavonol, phenols, tannin and proanthocyanidin, while the essential oil contained dimethy disulfide, dimethyl trisulfide, (methyl methylthio) methyl, 2,4-dithiapentane (11.35 percent) and (methylthio) acetic acid, 2- (methylthio) ethanol, 3-(methylthio) - and propanenitrile (7.20 percent). The fresh extract had higher radicals scavenging activity than the essential oil or dried extract, with 50 percentage inhibition of DPPH, hydrogen peroxide and lipid peroxidation at a concentration of 35.0 ± 0.12, 19.3 ± 0.11 and 17.9 ± 0.15 μg/ml respectively. Oral administration of methanolic extract of RTV in 125, 250 and 500 mg/kg to female Wistar rats significantly inhibited reduction of glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT). The extracts also inhibited (p< 0.05) lipid peroxidation in normal, high cholesterol and diet induced atherosclerosis fed rats in a dose dependant manner. Also the extract (250 and 500 mg/kg/bwt/day) caused a significant (p<0.05) improvement in body weight of treated animals compared with untreated hypercholesterolemia control rats. The extracts also protected significantly (p<0.05) against atherogenic diet induced liver damage or fatty streaks formation in the aorta as revealed by histological examination. The anti-cholesterolemia and anti-atherosclerotic activities of the extract compared favorably well with standard drugs Gemfibrozil and Atorvastatin respectively. Conclusively, rhizomes of T. violacea possess significant anti-atherogenic activity and its mechanism of action(s) may be due to its antioxidant and anti-hypercholesterolemia properties. The results of this study also suggested that rhizome of T. violacea is relatively safe for human consumption and it may be used as an alternative to garlic.

- Description: In many parts of Africa, the cultural practices and customs that were in use over the ages are still largely in place today. Many of these practices discriminate against individuals and compromise their human rights, particularly the rights of African women. The aim of this investigation is to study customary marital practices among the amaXhosa in order to establish their effect on modern amaXhosa society. In addition, this includes other discriminatory practices, such as the diminished status of wedded women. Within the study, the social status of women before and after 1994 is dealt with as depicted in the selected texts. The study further determines the current social status of married women under the current dispensation and finds out whether the rights of married women are sufficiently recognised in the texts under discussion. It is clear therefore that whilst Africa has made good progress on the political front, the same cannot be said for some of the cultural values that are still adhered to in the present age. This applies in particular to the rights of women in an African society. Globally, women and girls suffer the harmful and life-threatening effects of discriminatory traditional and cultural practices that continue under the guise of social, cultural and religious ceremonies. In the democratic South Africa, there is growing concern and awareness that some cultural practices are harmful to women and girls. The study analyses a number of texts namely, novels and drama, that were published before and after the 1994 era in South Africa with aims and objectives being outlined in Chapter 1. Chapter 2 is devoted to the theoretical framework, which includes the general theory pertaining to the status of women, feminism and human rights. Secondly, it deals with African theory pertaining to the status of African women as well as their rights; finally, it reflects on the role of women in societies where traditional marriage custom is still in use. Chapter 3 analyses the depiction of customary marriage as a theme in isiXhosa prose before and after 1994. Chapter 4 examines the depiction of customary marriage in v isiXhosa drama before and after 1994 and focuses more on human rights elements. Chapter 5 summarises the arguments distilled from the analysed works. The researcher came to the conclusion that the practice of forced marriage does not occur in amaXhosa society only but it is also found on a wider scale on the rest of the African continent and beyond. The study was concluded with a set of recommendations that were made to combat the scourge of anti-feminism that is found in modern society.

- Description: The purpose of this study was to determine the role Local Government can play in the Department of Basic Education with the aim of addressing the enormous challenges faced by the Department of Basic Education with specific reference to the Province of the Eastern Cape. Currently the Department of Education in the Eastern Cape gets regular media coverage for the wrong reasons. Problems highlighted by the media normally include the following; over-crowded classrooms; mud schools; lack of ablution facilities at schools; delays in delivery of text books and stationary; shortage of teachers; unpaid teachers and the bungles with school transport and school nutrition programmes. Currently the National Government and Provincial Government have jurisdiction over basic education. An in-depth literature study was conducted in order to get insight in the Department of Basic Education in the Eastern Cape with its numerous problems and challenges that are crippling education in the province. The researcher also deemed it necessary to conduct an in-depth literature study on Local Government’s role in the education system in other countries e.g. USA, Wales, Great Britain and Nigeria where education is managed and financed by Local Government. Empirical studies were done through face-to-face interviews with the sample population from school principals, teachers, education specialists, administration officials and parents serving on School Governing Bodies in the Nelson Mandela Bay Metropole. The findings of the study suggested that Local Government is not yet in a favourable position to control the entire Department of Basic Education, although certain functions can be shifted to Local Government e.g. school transport, school nutrition programme; teachers’ salaries. The general feeling is that councilors at Local Government level are more likely to be aware of and sympathetic to the needs of their communities than Ministers and MEC’s. Through the relevant data the researcher has drawn certain conclusions and recommendations were made to alleviate the plight of education in the Province of the Eastern Cape.

- Description: This dissertation is concerned with the phenomenological question of lack of care in the face of Martin Heidegger’s placing care as a base for being. More specifically with the question: How is Heidegger’s ontological notion of care to be understood from within the contexts of healthcare, in general, and nursing in particular. Furthermore, deep within this notion of care there is always the option to not care which, although care is always contained in the various modes of Heidegger's Dasein, can be a contemporary enigma demanding investigation. In approaching the interpretation of what it is to care, the question will be confronted on three fronts a to interrogate, in the context of healthcare, Heidegger’s conception of the phenomenological situation of care in his writings up to and including his Being and Time; b then to delve into the phenomenon of lack of care that seems to have appeared in the provision of healthcare in recent times; and, in an attempt to explain this lack, c to expand on Heidegger’s early conception of care more broadly out into the world by postulating a diachronic emphasis by introducing elements from the developmental psychology of Erik Erikson. It is argued that this is necessary in order to begin to understand provenance of the notion of lack of care within the sphere of healthcare. As nursing is considered an epitome of caring, the profession will be used as a vehicle to illustrate the phenomenon of lack of care and how this is possible when care is the basis of Being in the world. Thus the final section will bring out through the lens of lack of care the predicates of caring as they apply to the healthcare professions, and, just as importantly, other areas of human endeavour, for that matter. Thes predicates, it is postulated, are an accretion of five elements: development of the care-of, assumption of some level of authority, introduction of curiosity into the engagement with the world of people and things, an understanding of the role of empathy, and, finally, advocacy in the face of disturbance. It is further postulated that none of these predicates are a given, that, in an enabling environment, they unfold out of each other to create a caring person. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2015

- Description: This study evaluated the coverage of the 2016 #FeeMustFall students’ protests in Eastern Cape Universities by the Daily Dispatch, which is a daily newspaper published in the Eastern Cape Province. The study employed both quantitative and qualitative research methods. Quantitative data were collected and analyzed through content analysis of the Daily Dispatch Newspaper while the qualitative data collected through focus group discussions among selected students of the University of Fort Hare were analyzed using thematic analysis. The study revealed that 31 stories were published by the Daily Dispatch Newspaper during the period of the protest. The tone of the stories suggested that the Daily Dispatch Newspaper was objective in its reportage. Furthermore, framing analysis of the stories showed that conflict news frame was most prominent in the #FeeMustFall students’ protest stories followed by the attribution of responsibility and human-interest frames. Thematic analysis of the focus group discussions revealed that the type of news frame used for the #FeeMustFall student’s protest stories influenced the thoughts and perceptions of readers as the news frames generated similar audience frames. These findings confirm the views highlighted by the agenda setting and framing theories, which underpin this study. This study indicates that news framing plays a significant role in readers’ perception and as well, defines the way information is presented by readers.

- Description: The aim of this study was to explore experiences of Foundation Phase male studentteachers during teaching practice. Four Bachelor of Education Foundation Phase male student-teachers were selected for the purpose of this study. Venturing of males in Foundation Phase specialisation is phenomenon. Foundation Phase has been viewed as a female territory for many years. As a result, there are few males teaching in FP. The study employed the qualitative approach as a suitable approach. As the study sought to explore experiences, a phenomenological design was followed. In a true phenomenological design, unstructured interviews and personal diaries are used for data collection. In this study data were collected through unstructured interviews and personal diaries of the participants. I employed interpretivism as a research paradigm. The study found that despite South Africa being a democratic country Foundation Phase is still viewed as a female space. Findings reveal that male student-teachers feel that in a democratic country, gender equality should be exercised. The study revealed that teaching profession is undermined. As much as participants reported about insecurities, they also reported about the benefits of being a male studentteacher in Foundation Phase specialisation. One of the benefits reported is knowledge and understanding of child development theories. The participants reported that during TP, they were seen as role-models, as father figures and resources. The research recommends that Initial Teacher Education Programme should do more in preparing male student-teachers venturing in Foundation Phase. The research also suggests that all stakeholders involved in education should have a programme focusing on developing teaching profession to be a prestigious profession. The government and all education stakeholders should also focus on gender equality within FP specialisation, both in Initial Teacher Education institutions and in schools.

- Description: This study examines the impact of children’s grants on household access to food, education and health care. In the face of increased poverty and socio-economic inequalities, social grants are a critical poverty alleviation intervention implemented by the government of South Africa. The children’s grants are offered as part of the social security system which is provided for in the Republic of South Africa Constitution of 1996 and the Social Assistance Act of 2004. The basic needs conceptual framework is the lens informing the focus of the study. Among other major findings, the study reveals that (a) childrens grants play a critical role in improvement of access to food, health care and education, (b) childrens grants are used as collateral, to access short term loans, and (c) social networks and home gardens play a significant role in aiding children’s grants to ensure household access to food, education and health care. , Thesis (MA) -- Faculty Social Sciences and Humanities, 2013
