- Description: Income Tax in South Africa is levied in terms of the Income Tax Act 58 of 1962 on taxable income, which, by definition, is arrived at by deducting from "gross income" receipts and accruals that are exempt from tax as well as deductions and allowances provided for in the Act. The Income Tax Act provides no guidance with regard to the taxation of illegal activities, except to prohibit the deduction of expenditure incurred in paying fines or in relation to corrupt activities, as defined. An analysis of the taxation of income derived from theft, fraud and prostitution and the deductibility of expenses relating to that income, is the question addressed in this thesis. In this thesis, an analysis was made of relevant case law in relation to the provisions of the Income Tax Act in an attempt to provide clarity. A brief comparison was also macie of American, United Kingdom and South African tax law. Similarities were found between the American, United Kingdom and South African tax regimes in relation to the taxation of income, but there appeared to be more certainty in America and the United Kingdom in relation to the deduction of expenses. The thesis concludes that recent case decisions have provided certainty in relation to income from illegal activities, but the tax status of the deduction of expenses remains uncertain.

- Description: Geomagnetically induced currents (GICs), resulting from adverse space weather, have been demonstrated to cause damage to power transformers at mid-latitudes. There is growing concern over possible GIC effects in the Southern African network due to its long power lines. Previous efforts to model the electric field associated with GICs in the Southern Africa region used a uniform ground conductivity model. In an effort to improve the modelling of GICs, GIC data together with Hermanus Magnetic Observatory geomagnetic field data were used to obtain a multilayered ground conductivity model. This process requires a definition of the network coefficients, which are then used in subsequent calculations. This study shows that GIC computed with the new network coefficients and the multilayered ground conductivity model improves the accuracy of GIC modelling. Then GIC statistics are derived based on the recordings of the geomagnetic field at Hermanus, the new network coefficients and ground conductivity model. The geoelectric field is modelled using the plane wave method. The properties of the geomagnetic field, their time derivatives and local geomagnetic indices were investigated to determine their characteristics in relation to the GIC. The pattern of the time derivatives of the horizontal geomagnetic field closely follow the rate of change of the north-south geomagnetic component rather than the east-west component. The correlation between the GIC and the local geomagnetic field indices was also investigated. The results show that there is a higher correlation between the GIC and the east-west components of the geomagnetic local indices than between the GIC and the north-south components. This corresponds very well with the orientation of the power lines feeding the power transformers at the South African Grassridge electrical substation GIC site. Thus, the geoelectric field driving the GIC at Grassridge is north-south oriented. Further, it is shown that the geomagnetic observation sites have a strong directional preference with respect to the Grassridge GIC site.

- Description: The geomorphology and dynamics of the Mfolozi River floodplain and estuary, located in the subtropical region of northern KwaZulu-Natal, South Africa, were considered with respect to existing models of avulsion and alluvial stratigraphy. The Mfolozi River floodplain may be divided into regions based on longitudinal slope and dominant geomorphic processes. Confinement of the Mfolozi River above the floodplain has led to the development of an alluvial fan at the floodplain head, characterized by a relatively high sedimentation rate and avulsion frequency, at a gradient of 0.10%. The lower floodplain is controlled by sea level, with an average gradient of 0.05%. Between the two lies an extremely flat region with an average gradient of 0.02%, which may be controlled by faulting of the underlying bedrock. Avulsion occurrences on the Mfolozi floodplain are linked to the two main zones of aggradation, the alluvial fan at the floodplain head, and toward the river mouth in the lower floodplain. On the alluvial fan, normal flow conditions result in scour from local steepening. During infrequent, large flood events, the channel becomes overwhelmed with sediment and stream flow, and avulses. The resulting avulsion is regional, and affects the location of the channel from the floodplain head to the river mouth. Deposits resulting from such avulsions contribute significantly to the total volume of sediment stored in the floodplain, and tend to persist for long periods after the avulsion. Contrastingly, on the lower floodplain, reaching of the avulsion threshold is not necessarily linked to large flood events, but rather to long-term aggradation on the channel that decreases the existing channels gradient while increasing its elevation above the surrounding floodplain. Resultant avulsions tend to be local and do not contribute significantly to the overall volume of floodplain alluvium.

- Description: The morale of educators in certain schools is very low. From the literature review I concluded that not all schools experience low morale in the same way. There are different factors impacting on the morale of educators at different schools. In this study, the causes of low educator morale, indicators of low morale, the importance of high morale and how low morale can be dealt with were addressed in order to provide guidelines to improve low morale. An empirical study was conducted and 2 schools in the Northern Areas of Port Elizabeth were used in this case study to establish to what measure the educators are exposed to the abovementioned variables. The data was analysed qualitatively and quantitatively. South Africa is divided into different demographic areas. The majority of people living in the communities where these schools are located are poor, unskilled, unemployed and the crime levels are very high. The socio-economic context within which these schools are located also has an impact on the morale of the educators at these schools and it affects their working lives. Educators, SMTs and principals took part in the empirical study so that their views can be compared and to facilitate the researcher to make recommendations on improving low educator morale. The research outcomes were analysed and deductions, recommendations and a need for further research were given. The empirical and literature study emphasised that the morale of educators is low in the schools and this morale status impacts on learners’ achievements, the health of the educators and the health of the institution. The educators in this study ranked their own morale status as low and some of the causes of the low morale according to the empirical study are lack of resources, ill-disciplined learners, uninvolved parents and an ineffective management style of the principal.

- Description: This paper outlines the design of gPF, a fast packet classifier optimised for parallel execution on current generation commodity graphics hard-ware. Specifically, gPF leverages the potential for both the parallel classi-fication of packets at runtime, and the use of evolutionary mechanisms, in the form of a GP-GPU genetic algorithm to produce contextually opti-mised filter permutations in order to reduce redundancy and improve the per-packet throughput rate of the resultant filter program. This paper demonstrates that these optimisations have significant potential for im-proving packet classification speeds, particularly with regard to bulk pack-et processing and saturated network environments.

- Description: The educational reform policy in Namibia adopted the principles and practice of learner-centred education, a policy based on constructivist epistemology. This approach emphasises that learners are constructors of knowledge and that they must discover information and construct their own learning. Constructivist techniques require the use of critical thinking through learners’ active involvement in the learning process. The aim is for learners to use critical thinking to identify problems, ask questions, reason, examine and solve problems in real situations and make sound decisions. This approach provides learners with activities and experiences that stimulate them to learn to think for themselves and to ask questions. Therefore, teachers need to design activities that require learners to think critically and act independently through mastering these various modes of inquiry. The purpose of this study was to explore how the selected Grade 10 Life Science teachers understand and implement critical thinking in their teaching practice. I conducted the study in two secondary schools from the Omusati region in Namibia using a case study to gain insight into the implementation of critical thinking. Three data collection instruments: interviews, document analysis and class observations were used. The reason for conducting this study was to gain a better understanding of how teachers use various strategies to foster critical thinking skills in Life Science and the challenges they experience in teaching in secondary schools. The results of the study revealed that teachers have a theoretical understanding of what critical thinking implies and the role it plays in learning. They are also aware of the strategies used to develop critical thinking skills. However, these theoretical perspectives do not reflect in their teaching in that some of the strategies that the teachers used did not bring about meaningful learning. Learners are still required to recall factual knowledge, thus active involvement of the learners is limited. The study also revealed that there are specific issues that hamper the implementation of critical thinking, which include superficial understanding of learner-centered education, teacher-tell approach, overcrowded curriculum, inexplicit syllabus, lack of good examples from the textbooks and examinations, too short lesson periods, lack of language proficiency and lack of professional development. The findings indicate that despite the theoretical understanding of the teachers in this study, their actual practice of developing critical thinking skills is problematic. The study concludes that teachers should be encouraged to design better-structured activities in order to involve learners beyond just being listeners. In light of these findings, the study recognizes a need for ongoing in-service professional development to support teachers in modelling critical thinking to their learners and to teach them to think critically. The findings of the study will serve to inform both my and my colleague’s professional practice as advisory teachers with regard to what to focus on when advising and supporting the teachers in schools.

- Description: preprint , This paper reports on the writing of grade 7 learners in English as an additional language at four differently-resourced schools in the Eastern Cape Province, South Africa. Because grade 7 is the start of the senior phase of schooling, it is vital that learners achieve grade-level competence in the language used as medium of instruction. Learning outcome five which states that ‘the learner will be able to use language to think and reason, as well as access, process and use information for learning’ (Department of Education 2002) is particularly relevant. The primary research question asked what the writing practices in grade 7 additional languages were, and how these contribute to the development of learners’ writing. The findings were that literacy practices at all four schools privilege grammar exercises and personal, expressive writing. In terms of Cummins’s (1984) constructs of BICS (Basic Interpersonal Communicative Skill) and CALP (Cognitive Academic Language Proficiency), learners’ written competencies are mainly conversational (BICS). The personal expressive texts which predominate in learners’ writing have done little to develop a formal, impersonal academic register (CALP). Learners need to become familiar with the more abstract impersonal factual genres associated with disciplinary-based knowledge.

- Description: Trees provide a wide range of goods and services to rural households which, when incorporated into their livelihood strategies, help reduce their vulnerability to adversity. Governments and policy makers often ignore the contribution made by trees and consequently resources are focussed on cash crops and livestock. Villagers in the Eastern Cape and Limpopo Province, South Africa utilise a range of trees from home-gardens for various purposes, although predominantly for fruit and shade. Trees are either planted or actively retained in households' home-gardens. There were noticeable differences between the villages in the Eastern Cape and those in Limpopo Province, particularly with respect to the overall density of trees per hectare and the number of species per household, both being significantly greater in Limpopo Province. The five most preferred species were listed for each village, revealing a preference for exotic fruit trees in Limpopo Province and a mix of exotic fruit trees and shade trees in the Eastern Cape. Households also retained useful indigenous species, predominantly fruit-bearing species. A range of factors constrain tree growing in home-gardens and households engage in practices to grow and maintain their trees. Not all of these constraints and practices were significantly different between the various localities.

- Description: Trees provide a wide range of goods and services to rural households which, when incorporated into their livelihood strategies, help reduce their vulnerability to adversity. Governments and policy makers often ignore the contribution made by trees and consequently resources are focussed on cash crops and livestock.

- Description: Diabetes Mellitus (DM) is the new epidemic in the world with 246 million people suffering from the disease at the moment and a projected increase to 380 million in 2025 (IDF, 2007b:36). The developing countries are the most vulnerable. Statistics state that SA and Egypt have the most diabetics on the continent. Globally, each year 3,8 million deaths are attributable to DM (IDF, 2007a). The Department of Health (DOH) and the Cacadu District Municipality (Eastern Cape) are serving a population of 102 721 in the Kouga and Koukamma areas, which covers an area of 5 992 km², with health care. There are 22 clinics with 28 registered nurses for all the clinics and between 3 and 9 lay health workers (LHWs) per clinic. For the purpose of this research study, the persons suffering from DM (±3550) in this area were taken into consideration (Strydom, 2005). DM is a chronic disorder and therefore patients should be able to manage their disease pattern for the rest of their lives (Healthline, 2008, Mbanya, 2006:12). In order to achieve this, continuous and effective patient education by health care providers are necessary. This disease affects more and more people each passing day, because of the rapid westernisation of the South African population, leading to more people attending clinics in the public health sector (Bonnici, 2002:32). There are specific guidelines laid down by the Department of Health (DOH) pertaining to the control and management of DM. Guidelines include the early diagnosis, treatment and patient education regarding DM (Department of Health, 1997, [revised 2004]). Evidence from previous research studies showed that not all registered nurses are aware of these guidelines and most have not been educated regarding the utilisation of these guidelines (O’Brien, van Rooyen & Carlson, 2006:36-40). In the clinics, the health care givers are confronted with a number of difficulties, such as a lack of funds to enable them to order adequate equipment and medicine. Another problem is the migration of registered nurses out of the country thus; there is also a shortage of staff to operate these clinics (Mkhize, 2004). The organisational structure in the clinics does not function optimally and there is a lack of communication between provincial, district and clinic level. Due to the above-mentioned challenges there is also a lack of efficient auditing systems to ensure quality assurance. Furthermore, a knowledge deficit pertaining to DM and the management thereof in all the groups participating in this study, namely the registered nurses, the lay health workers (LHWs) and the diabetic patients was found. The empowerment process of the LHW is not explored fully and therefore not executed to its full potential. To be able to improve the management of DM in this region, it is important to know what the difficulties are that the health care givers as well as the patients experience in relation to this issue. This study therefore explored and described these difficulties. The research was based on a qualitative, quantitative, explorative, descriptive and contextual research design. Health care givers as well as diabetic patients attending clinics in the Cacadu region of the Eastern Cape have been requested to complete questionnaires pertaining to their knowledge of Diabetes Mellitus. The current organisational structure of the provincial department of health was explored and findings analysed using the activities of the management process (Muller, 2006:106). The SA Government is committed to combining the national human resource development strategy with the rapid upgrading of service delivery to all of the nation’s communities. Stemming from this undertaking, suitable members of the community are to be trained as LHWs. LHWs are to play an integral role in strengthening the abilities of the community to empower themselves to participate and take responsibility for their own health and wellness (Department of Health, 2001a:4). From the research, it was found that the above-mentioned national plan had been implemented, but is not functioning at optimum level due to several shortcomings/deficits. Proposed guidelines were therefore designed to address the shortcomings and fragmentation of the plan. As specific knowledge deficits in DM were identified during this research study, general educational guidelines were included for the registered nurses and the diabetic patients. The LHW was identified as an indispensable link in the chain of efficient health care and therefore, specific educational guidelines on DM were generated to prepare her for the role. With her knowledge, insight into DM and the management thereof and newly required skills in educating and supporting of the patient, she could be an asset in the road to optimum self-care for the diabetic patient.

- Description: The present paper will inform about three studies that seek to make a contribution to the area of self-conscious emotions, namely guilt and shame, and their consequences for intergroup relations in a South African context. As with previous research, this research investigated whether belonging to a particular group (i.e. being a white South African) is likely to evoke feelings of collective guilt and collective shame when reminded of the atrocities of Apartheid, even though the individual members did not personally contribute to their group’s negative history. The first study aimed to investigate experimentally the effects of experienced collective ingroup guilt and shame on the desire to make reparation. The second study aimed to test the relationship between guilt/shame and reparation of white South Africans in the field. Furthermore, the second study aimed to account for the dialectical aspects of the intergroup situation by exploring guilt/shame and reparation of white South Africans as expected by young black South Africans (as members of the previously oppressed group). The third study aimed to replicate the differences between experienced guilt/shame/reparation and reported ingroup identification by white South Africans and the expected guilt/shame/reparation from white South Africans and reported ingroup identification by black South Africans as found in the study 2. In addition, the third study aimed to control the antecedents for collective guilt and for collective shame. It also explored the impact knowledge about atrocities of the ingroup (white participants) has on emotions and reparation attitudes and whether perceived status relations at present and in the future impacts the emotions as well general reparation attitudes.

Habitat and foraging models as aids in the identification of priority areas for mitigating actions to reduce the incidence of electrocutions of the threatened Cape Griffon Gyps coprotheres in the Eastern Cape

- Description: The Cape Griffon Gyps coprotheres is listed as a globally threatened species, because of threats posed by, inter alia, poisoning, loss of habitat, food shortages, electrocutions and drowning in high-walled farm reservoirs. The Cape Griffon has undergone major decline in South Africa, including the Eastern Cape. A detailed investigation into the causes of this decline is vital to ensure the survival of the species. Since it is known that electrocution on powerlines is a major cause of mortality of the griffons in the Eastern Cape, the study therefore focuses on this factor in this region. More specifically, the overall aim or objective of the study is to investigate, through the application of appropriate GIS techniques, the use of descriptive, empirical, habitat and foraging models to prioritise powerline networks, in the Eastern Cape, for mitigation to prevent electrocution of Cape Griffons Gyps coprotheres. The specific activities associated with the aim of the study are: (1) to identify the broad habitat types used by the griffons, (2) to determine the mean daily foraging range size of the griffons, (3) to map currently active foraging ranges and to categorise them according to their role, and the level of importance, in the foraging and breeding behaviour of the species, (4) to map the locations of networks of griffon-unfriendly powerline networks, and (5) to integrate the outcomes of (1) to (4) above, to produce a spatially explicit product that ranks griffon-unfriendly powerline networks according to their priority level for mitigation. The study uses simple descriptive models to investigate, spatially, the threat posed by griffon-unfriendly powerlines to the Cape Griffon in the Eastern Cape. The modelling approach includes a broad level simple habitat model (Categorical model), a Maxent model, a spatial foraging model and an electrocution model. Several map outputs were produced from the analyses. Cape Griffon habitat was successfully modelled using ecological input variables: biome, vegetation xvii type (suitable/unsuitable for griffon foraging), stock (cattle, sheep and goats), and stock farming types (commercial & communal). All outputs were modelled through the use of a Geographical Information System (GIS). Opportunistic sightings data were used for the study, which means that the data were collected on a non-systematic basis and are therefore considered incomplete. In ecology and zoogeography, incomplete datasets are common. To address this issue, a maximum entropy (Maxent) model was applied to the available dataset. Maxent produces predictions or conclusions from incomplete information, and was therefore useful for this study. The mean daily foraging area (coverage) of the Cape Griffon in the study area was estimated from published and unpublished marked bird studies conducted elsewhere, but in generally similar habitats. Based on all the data from these studies, it was considered appropriate to use a circular area, with a radius of 40 km, to represent the mean daily foraging range of the Cape Griffon in the Eastern Cape. It was considered appropriate to use a roughly circular area to depict the daily foraging area, given that the Cape Griffon qualifies as a central place forager. This means that the griffons are tied to a permanent site (roosting site or breeding site) and forage within a certain area around that central site. The mean daily foraging area (40 km) was applied to the currently active griffon sites: breeding sites, regular roosting sites, seasonal/occasional sites, and roosting sites (uncertain status). This produced four foraging area types, which formed the basis for the creation of two spatial foraging area models: Hierarchical Foraging Area Model (HFAM) and the Intersecting Foraging Area Model (IFAM). The HFAM produced three outputs: Primary, Secondary and Tertiary Foraging Areas. These three areas represent the hierarchical presentation of the relative importance of the four foraging area types. The outcome was areas of different predicted griffon occurrence: ‘high’, ‘medium’, ‘low’. The IFAM is essentially an extension of the HFAM, which represents a single area where foraging ranges based on all four types are intersected. The outcome represents the area of predicted highest griffon occurrence. The identified areas of different predicted griffon occurrence, or density (outputs of the HFAM and IFAM), were individually intersected with the layer that indicates the locations of the ‘unsafe’ powerlines. These intersects are depicted in hierarchical mode and expressed according to a number of four risk categories (very high, high, medium and low). The final spatial output of the study is a map that identifies priority powerlines for mitigation against griffon mortality caused by electrocutions and collisions with powerline infrastructure.

- Description: Women are subject to a number of societal recommendations about what it means to be an 'ideal' woman. These recommendations take the form of social scripts, constructing an idea of ideal femininity, which women must perform in order to be socially accepted and successful. 'Emphasized femininity', a white, Western, script of femininity is dominant and has been critiqued by feminists, social theorists, and individual women for the limits that it places on women's behaviour. As a result a number of alternative scripts of femininity have arisen. These scripts can provide alternatives to restrictive understandings of female sexuality and beauty - they can serve to challenge 'appropriate' feminine behaviour and hence allow women to live more freely. Raunch femininity is a contemporary alternative that uses sexually explicit public performance, and encourages specific body and dress norms, in an attempt to challenge the norms of emphasized femininity. This thesis looks at raunch femininity, specifically its norms of sexuality and beauty, in the hopes of understanding what the effects of such a script are on women's behaviour. Theoretical understandings and explanations of women's lives are often contradicted by reports that women provide of their lived experiences. For this reason, this thesis investigates the lived experiences of women who self-identify as subscribers to this script in order to assess to what extent superficial expressions of freedom have deeper effects on women's freedom. The tension between theory and empirical reports is evident. However, in many cases, the reports of research participants reveal that the script of raunch femininity, like other scripts of feminine behaviour, has its own limits that women must abide with in order to be accepted. This thesis argues that these limits outweigh the benefits of this script. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The problems of illiteracy in health contexts have been well documented in the literature and include such serious repercussions as medication non-compliance and failure to seek medical help during the course of an illness. The Rapid Estimate of Adult Literacy in Medicine (REALM) is a standardised health literacy test developed in the United States that has been previously administered and researched in South Africa (Lecoko, 2000). It is an objective vocabulary test, designed as a screening instrument to identify the health literacy levels of patients in clinics, which uses item recognition of 66 health-related words. Lecoko found that, in a South African setting, only 8 out of the 66 words in the US-developed test could be deemed acceptable. Therefore, the current study focused on the principled relexicalisation of the REALM, using words gathered from health information and promotional texts in local clinics, hypothesising that this would improve its applicability. After administration to a statistically similar group of respondents, the number of acceptable words on the test increased from eight to 38. Thus it is concluded that principled relexicalisation may be one way of improving the applicability of standardised health literacy tests to local populations and settings. However, the limitations of standardised tests may prove to be a significant barrier overshadowing the value of relexicalisation.

- Description: The problems of illiteracy in health contexts have been well documented in the literature and include such serious repercussions as medication non-compliance and failure to seek medical help during the course of an illness. The Rapid Estimate of Adult Literacy in Medicine (REALM) is a standardised health literacy test developed in the United States that has been previously administered and researched in South Africa (Lecoko, 2000). It is an objective vocabulary test, designed as a screening instrument to identify the health literacy levels of patients in clinics, which uses item recognition of 66 health-related words. Lecoko found that, in a South African setting, only 8 out of the 66 words in the US-developed test could be deemed acceptable. Therefore, the current study focused on the principled relexicalisation of the REALM, using words gathered from health information and promotional texts in local clinics, hypothesising that this would improve its applicability. After administration to a statistically similar group of respondents, the number of acceptable words on the test increased from eight to 38. Thus it is concluded that principled relexicalisation may be one way of improving the applicability of standardised health literacy tests to local populations and settings. However, the limitations of standardised tests may prove to be a significant barrier overshadowing the value of relexicalisation.

- Description: The aim of this research was to assess three hierarchical aspects of alga-grazer interactions in intertidal communities on a small scale: spatial heterogeneity, grazing effects and spatial stability in grazing effects. First, using semivariograms and cross-semivariograms I observed hierarchical spatial patterns in most algal groups and in grazers. However, these patterns varied with the level on the shore and between shores, suggesting that either human exploitation or wave exposure can be a source of variability. Second, grazing effects were studied using manipulative experiments at different levels on the shore. These revealed significant effects of grazing on the low shore and in tidal pools. Additionally, using a transect of grazer exclusions across the shore, I observed unexpected hierarchical patchiness in the strength of grazing, rather than zonation in its effects. This patchiness varied in time due to different biotic and abiotic factors. In a separate experiment, the effect of mesograzers effects were studied in the upper eulittoral zone under four conditions: burnt open rock (BOR), burnt pools (Bpool), non-burnt open rock (NBOR) and non-burnt pools (NBpool). Additionally, I tested spatial stability in the effects of grazing in consecutive years, using the same plots. I observed great spatial variability in the effects of grazing, but this variability was spatially stable in Bpools and NBOR, meaning deterministic and significant grazing effects in consecutive years on the same plots. Both the significance in grazing effects and spatial stability depended on the level of resolution (species, functional, biomass) at which the algal assemblage was evaluated, suggesting hierarchical variability. In order to be able to predict spatial variability in the effects of grazers in the upper eulittoral zone using biotic and abiotic micro- and macrofactors, a conceptual model was proposed, based on data from several multiple-regressions. This linked the interactions among three elements: idiosyncratic heterogeneity, micro and macrofactors. This suggests that spatial variability can be a product of these factors, while spatial stability can be caused by the same or different combinations of factors. In conclusion, grazing and other ecological phenomena must be studied hierarchically, not only through spatiotemporal scales, but also at different levels of resolution, as these also influence our perception of patterns.

- Description: [From introduction]: In the cities of the global South elites are often desperate to repress the reality of the shack settlement. Maps are printed in which shack settlements appear as blank spaces, laws are passed that assume that everyone can afford to live formally and, in the name of order and development, the poor are beaten out of the cities. The great elite fantasy is the creation of 'world class cities' – shiny, securitised nowherevilles in which the poor understand that their place is to live in some peripheral ghetto and only come into the city as menial workers. But from City of God to Slum Dog Millionaire and now District 9 cinema has put the shack settlement in the mall and at the heart of how Rio, Bombay and Johannesburg feature in the global imagination.

- Description: This study critically examines my classroom practice in teaching young learners aged four-and-a-half to six years old. It focuses on the following research question: How can I create a stimulating environment in my classroom to promote awareness of and a love for reading? My classroom-based action research methodology places me, the practitioner, at the centre of the investigation. The work examines closely my professional values and my strong belief in the capacity of learners to be curious, absorb and make sense of what they encounter and experience in a stimulating environment. It investigates how such an environment develops the potential of learners to love and embrace reading. The process of engaging reflectively and analytically in practitioner research has helped me to gain a better understanding of my learners’ needs and to improve the ways in which I promote reading in the reception year of formal schooling. I claim that the creating of a stimulating environment in my classroom is grounded in my ability to motivate, model and scaffold the learners to engage in reading confidently. Together, the learners and I have created a living theory of education, one that is open to further reflection and development. Ongoing interaction between theoretical discourse and practical experiences enable me to develop my professional knowledge and to synthesize my values and practice. The investigation continuously confirms the advantages of a print-rich environment and how it can be used to promote a love for reading amongst young learners. The claims and knowledge generated in this study are personal and true for me, while the living transformational process demonstrates how I have developed professionally.

- Description: This study was conducted as a case study at the rural Ethridge Junior Secondary School which is located in the Eastern Cape Province of South Africa. The aim of the study was to investigate how school gardens could be used to teach environmental activities in the Technology Learning Area at senior phase. The study examined how environmental activities in the school garden can be used to develop technological concepts and knowledge and for developing technological problem-solving abilities. Furthermore, it examined the relationship between technology, society and environment, and how structural and socio-cultural factors influence the use of environmental activities in the school garden. The overall approach was a case study. The data was generated using qualitative methods such as interviews, observation, workshops and document analysis of learners’ work. Of all the research tools used, the interviews and observations were the most fascinating and informative methods. The study focused on various activities undertaken by Grade 8 learners in their Technology Learning Area. These activities were compost making, planting and irrigating. The study showed how learners from poor rural homes can use available resources and suitable technology processes to plant vegetables. In terms of resources, virtually all resources used in the study were free, sourced locally and/or borrowed. This indicated that even in poor, rural areas materials are available to make structures and complete activities. In terms of available suitable technology, learners in the study explored the use of old car tyres for planting containers that can be easily transported. They also, using easily available resources such as tin cans, explored how to design and construct an effective, low-water consumption, low cost irrigation devise. The study explored the achievement of Learning Outcomes (LO) using the school garden. This study uses the school garden as a teaching aid to achieve the three main LO’s in the Technology Learning Area (LA). This study has also indicated that LO’s are sometimes intertwined, that is to say that more than one can be achieved at the same time. The three activities (compost making, planting and irrigation) were used to attain the required LO’s. The study indicates that LO 1 (related to applying technological processes and skills ethically and responsibly) can easily be achieved by designing a compost box and a compost heap, making them and evaluating the process. LO 2 (related to understanding and applying relevant technological knowledge) could easily be achieved in the irrigation activity, and LO 3 (related to demonstrating interrelations between science, technology, society and environment) could easily be attained in both compost making and planting. The study also showed that curriculum activities, such as those used in this study, are influenced by socio-cultural and structural factors that influence the curriculum contextualizing process. The main findings of the study are captured in five analytical statements. These form the basis for a set of recommendations to inform the use of school gardens as a resource for technology teaching in Ethridge Junior Secondary School, and possibly for other rural schools.
