  • Description: The role that women play in the economy of any society is a desirable goal for equity and efficiency considerations. Just as with the rest of the world, the South African women lagged behind their male counterparts within the economic empowerment space and in the formal labour force. However, the role of women has undergone some transformations with issues relating to employment opportunities, such that their labour force participation has risen considerably since 1994. The female labour force participation rate is still seen to be persistently lower compared to the male participation rate even in the second decade of democracy. The rate of women labour force participation is even lower than the average. On the other hand, the increases have also been coupled with the rising rate of unemployment among women. The objective of this study was to investigate the determinants of female labour force participation in the South African labour market. The study uses a regression analysis on a cross sectional panel data covering a period of 1995 to 2010. Unlike most popular beliefs, the findings of this study reveal that fertility though not statistically significant, positively influences labour force participation of women. Other variables that are statistically significant in explaining female labour force are HIV/AIDS, marital status, age, household income and education. Race was found to be insignificant in explaining female labour force participation in the South African labour force.

  • Description: Careful examination of the composition and concentration of malicious traffic in transit on the channels of the Internet provides network administrators with a means of understanding and predicting damaging attacks directed towards their networks. This allows for action to be taken to mitigate the effect that these attacks have on the performance of their networks and the Internet as a whole by readying network defences and providing early warning to Internet users. One approach to malicious traffic monitoring that has garnered some success in recent times, as exhibited by the study of fast spreading Internet worms, involves analysing data obtained from network telescopes. While some research has considered using measures derived from network telescope datasets to study large scale network incidents such as Code-Red, SQLSlammer and Conficker, there is very little documented discussion on the merits and weaknesses of approaches to analyzing network telescope data. This thesis is an introductory study in network telescope analysis and aims to consider the variables associated with the data received by network telescopes and how these variables may be analysed. The core research of this thesis considers both novel and previously explored analysis techniques from the fields of security metrics, baseline analysis, statistical analysis and technical analysis as applied to analysing network telescope datasets. These techniques were evaluated as approaches to recognize unusual behaviour by observing the ability of these techniques to identify notable incidents in network telescope datasets

  • Description: This treatise reports on a qualitative exploratory study that was aimed at identifying and describing the challenges experienced by single mothers who were students at a South African university. The researcher is of the view that single parenthood is a global challenge but very little has been done to explore this phenomenon in South Africa. A purposive convenience sample of four voluntary full time registered single mother students at a university in the Western Cape Province was utilised in the study. The participants ranged in age between eighteen and twenty three years and were English second language speakers. In-depth individual interviews were conducted with the four participants and the data were analysed into qualitative themes. The following main challenges for the sample of single mother university students emerged from the data: (i) Financial challenges. (ii) Concern for the general wellbeing of children. (iii) Difficulties regarding the separation of mother and child. (iv) The importance of tertiary education in finding future employment. (v) Dual role stress. Sub-themes within these main themes were also identified and discussed. Recommendations for future research, based on the findings of this study, are also offered.

  • Description: Integrative Summary: Small to Medium Business Enterprises (SME's) are widely recognised as the driver of economic growth. SME's are responsible for employing large sections of the working population and, in doing so, facilitate the development of skills for many thousands of workers. Whilst SME's may differ (according to various definition criteria such as size or turnover) from other types of organisation, they share one common denominator across all organisations: their overall effectiveness depends largely on the individual and collective people that make up the organisation -their employees. In this context the central question relevant to the research is "how do SME's retain their valued employee managers?" A quantitative research method was applied in the research. Data was collected by way of a structured self-administered survey questionnaire designed from a post positivist paradigm. The survey was constricted by way of modifying and adapting previous surveys designed to investigate factors that influence staff retention, to be relevant to managers employed by SME's. The sample consisted of 35 managers employed by SME's in and around East London in the Eastern Cape, South Africa. The results of the research give rise to a number of clear indicators on the key retention factors of employee managers. Based on the research results SME's that want to have the best chance of retaining their employee managers need strong and effective leadership within the organisation, must address soft organisational factors that are conducive to an open and trusted working environment and the roles of managers must have inherent job factors that allow a sense of freedom to plan and execute tasks autonomously. Economic factors such as pay and financial benefits were identified through the research as being the least important factor when it came to manager retention. These conclusions provide SME owners and senior managers with insight into the factors that are most likely to influence their ability to retain employee managers.

  • Description: The impacts of climate variability have been of global concern for many years. These impacts are affecting economic, social, cultural, agricultural, health and political structures in different countries. Although the impacts of climate variability on agricultural production are being experienced globally, it is generally accepted that developing countries are the worst affected due to a variety of reasons. Given the high susceptibility of developing countries to climate variability, this study maps and analyses the impacts of climate variability on agricultural production, food production, availability and access in Chivi District, Zimbabwe. The study aimed at finding out experiences, so it used a qualitative approach. The study uses in-depth and focus group discussions to collect data. Chivi district is experiencing erratic weather patterns which are impacting agricultural production in general and food production in particular. Consequently, food availability and access is on the decline in the district. Even though smallholder farmers have devised coping and adaptation strategies, this is not sufficient to help them fully deal with the impacts of climate variability. This is due to their limited assets, inadequate technology and climate information among other things. In an attempt to assist these smallholder farmers cope and adapt to the impacts of climate variability, NGOs and Government Departments have instituted a number of community interventions. This assistance includes agricultural extension services, farming input support and provision of climate change information and a lot of other things. In view of these findings, the study recommends the universal adoption and growing of small grain drought resistant crops in climate variability affected Chivi. It further recommends that farmers adopt conservation agriculture, get into partnerships and co-operatives to practice irrigation gardening where those without water sources provide equipment, labour and knowledge. The study also recommends that more climate science research be conducted in Zimbabwe by both NGOs and Government Departments. Furthermore, government and NGOs should provide more support for farmers in the form of climate change related training, knowledge and technology transfer among other things. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2013

  • Description: The modern workplace continues to transform at a radical and accelerated pace and successful and competitive organisations are able to turn their strategies into action faster, manage their processes more efficiently and maximise their employees’ contribution and commitment (Brewster, Carey, Grobler, Hollard and Wärnick, 2010:5). In addition, Vestal (2009:6) adds that one of the biggest challenges that managers face at the moment, is to find ways to engage employees in the organisation and build a sense of belonging that, hopefully, will support retention and long term commitment. This research study aimed to explore and describe the nature and extent of employee engagement among nursing employees working in private healthcare. This exploration also encompassed five facilitators which are considered to be crucial in the promotion of an engaged workforce. The identified facilitators include: leadership behaviour, working environment, communication, training and development and rewards and recognition. This was attained by using a quantitative, exploratory, descriptive and contextual research approach. A structured questionnaire was used to collect data from nursing employees working in one of the private hospitals in the Nelson Mandela Metropole. From the data, the overall degree of employee engagement was established as well as the significance of the five identified facilitators in employee engagement. Based on the analysed data, guidelines for the advancement of employee engagement are proposed that can assist management in the development of employee engagement practices and strategy formulation.

  • Description: This study is about exploring the factors that contribute to nursing students’ dropout at a public college. Lilitha College examination policy states that for a student to complete the Four Year Comprehensive Diploma Course, the student shall have passed all the four year courses. An increased student dropout rate has been identified to be affecting nursing student’s progress at Lilitha College of Nursing, East London Campus. This is a cause for concern and the researcher decided to investigate and explore the factors contributing to students’ dropout. This situation paralyzes the attempt by government to deal effectively with the shortage of trained nurses. The purpose of the study was to investigate and explore the factors that contribute to students’ dropout at Lilitha College of Nursing East London Campus. The objectives of this study were: To explore and describe experiences of students who dropped out from Lilitha College before course completion, to identify contributory factors related to increased students’ dropout rate, to come up with recommendations as how to curb the problem of student dropout and to ensure an increase of nursing students who complete at the end of the programme. This study followed a qualitative approach and explorative descriptive design. The population was all the students that have dropped out at Lilitha College of Nursing, East London Campus in the four year basic comprehensive programme from 2007 – 2011 at all levels of study. The sample size in this study was determined by data saturation, meaning that the data were collected to the point where no new information was obtained (Polit & Beck 2004: 308). A purposive sample of 15 former Lilitha students now working as Enrolled nursing assistants participated in this study. Data collection was divided into two sections, namely, demographic characteristics and face to face interviews. Demographic characteristics of the participants were obtained by asking questions related to age, sex, race, marital status, number of children per participant and the year of study at the time of dropping out. In section two of the study the interview guide was used for the purposes of data collection for this study, where four questions were formulated to guide the interview that was followed by probing questions. All tape recordings were listened to and transcribed verbatim. Field notes that were taken during unstructured interview were interpreted. The ideas that emerged from the interview sessions were then consolidated. Questions in the interview guide and their responses were drawn up and similar responses that arose from the interviews were grouped together. The identified major themes and sub themes were coded and categorized. Data belonging to each category were grouped together and analyzed and then the final remarks on the data analysis were completed. For most participants the course was frightening and difficult. They explained that they were exposed to a lot of information in a short space of time. In class, there was a lot of theory and in the wards there were skills to be learnt. Learners had to compile all the information and try to make sense out of it. Students follow up and support in the clinical facilities was reported as inadequate. The college should employ full time facilitators. This can improve teaching in the clinical area. The student should have mentors so that whenever they encounter a problem there will be people to assist and give them guidance. Through mentoring and support, student absenteeism can be controlled and students can gain self-confidence and learn more.

  • Description: As part of a drive to improve the quality of teachers, Zimbabwe introduced a school-based mentoring model in 1995, a move which regrettably seems not have borne fruit. Therefore, this study sought to propose an improved mentoring model for initial teacher training for primary school teachers. Efforts to improve the current mentoring could, however, be facilitated if they were informed by an empirically-based understanding of the shortcomings of the existing mentoring system for student teachers and teachers. In order to attain the above objective, this study adopted a multisite case study design, guided by the interpretive paradigm. A core of nine primary schools, drawn from the rural, urban and peri-urban areas of the Masvingo Province in Zimbabwe, was purposively selected to participate in the study. In the participating schools, key participants were student teachers and mentors, while school principals participated when they had time. A secondary group of primary schools were also identified to be used as validation of findings in a wider setting. An in-depth literature study on teacher education and mentoring was also carried out and this, combined with empirical data, illuminated the issues being investigated. The empirical data were primarily gathered through focus group and face-to-face individual semi-structured interviews, while participant observation (used in conjunction with informal unstructured interviews) and questionnaires were used to verify and triangulate data collected through the interviews. To safeguard the ethical integrity of the study, ethical approval from the relevant university committee, as well as the official consent of educational authorities, was obtained beforehand, as was the informed consent of individual participants. The research established that the support rendered to student teachers in the participating primary schools was largely inadequate and of a shallow mode, focusing primarily on facilitating the mastery of technical skills and the provision of psycho-social support, while being sorely deficient in empowering the student teachers with the skills and attitudes to reflectively and critically engage with their own and others‟ teaching practices. The mentoring was taking place in the context of field experience, organised along the apprenticeship model, hence located in an outmoded traditional paradigm of field experience, something which is regrettable at a time when international best practices seek to move towards a reflective-inquiry-oriented paradigm. Secondly, the research found that the participating schools were not structurally or culturally ready to take significant teacher training responsibility; hence the schools, in their present state, could be seen as constraining the smooth functioning of the mentoring model. Thirdly, some mentor-based factors also seemed to inhibit the functioning of the mentoring model. These included teachers who were attitudinally indisposed to accept student teachers as their professional colleagues, preferring to relate to them hierarchically and vertically, thereby limiting the emergence of a culture of professional collaboration and reciprocal learning relationships. In similar vein, the mentors‟ lack of training limited their capacity of mentors to perform the extended range of mentoring functions necessary for supporting student teachers trained in 21st century schools. The above conclusions and implications point towards the following recommendations: Mentor support for student teachers should be extended from the present superficial level to include functions that are oriented towards reflective practice. However, for this to happen, some adjustments will need to be made in the schools. These include, most importantly, making time available for mentoring activities. In order for the mentors to be able to perform their mentoring functions knowledgeably, they must be made fully aware of what they are supposed to do by providing them with the official documents spelling out mentoring expectations in schools. Additionally, the commitment of mentors to their duties could be made more sustainable by putting in place a clearly defined reward structure that is fully recognized officially and integrated into the employee grading system. To make school environments more propitious towards mentoring, schools must be structurally modified and re-cultured to create slots for mentoring activities, provide opportunities for informal professional interaction among teachers, as well as establish professional engagement forums, such as school-based learning circles. The research also suggests that student teachers should be allowed to choose their mentors through providing them with opportunities for early contact with their prospective mentoring partners. In an attempt to close the gap between college-based modules and field-based school experiences, the research further recommends that college-based modules be delivered in a way that ensures that they are fully integrated with student teachers‟ field experiences. Finally, mentoring could be better facilitated if schools and colleges adopted a partnership arrangement that is more aligned to mentoring. This implies provisionally shifting from the present separatist to the HEI-led partnership model, while preparing for the adoption of a fully-fledged collaborative partnership in the long term. The research was, however, by no means carried out perfectly. It was somewhat limited by its failure to take into account the view of officials from the Department of Education, as well as the input of colleagues in teacher education. In similar vein, the researcher felt that a more nuanced and fine-grained picture of the participants‟ mentoring experiences could have emerged if he had spent more time in the field, something which limited resources and work commitments did not allow him to do. Some significant issues arose from this study, but which it could not pursue. These include exploring the possibility of coming up with a model of teacher education that integrates ITE and CTPD in the context of mentoring, as well as conducting a similarly designed research into the mentoring that is taking place in secondary schools.

  • Description: The revolutionary migration within the health care sector towards the digitisation of medical records for convenience or compliance touches on many concerns with respect to ensuring the security of patient personally identifiable information (PII). Foremost of these is that a patient’s right to privacy is not violated. To this end, it is necessary that health care practitioners have a clear understanding of the various constructs of privacy in order to ensure privacy compliance is maintained. This research project focuses on an investigation of privacy from a multidisciplinary philosophical perspective to highlight the constructs of information privacy. These constructs together with a discussion focused on the confidentiality and accessibility of medical records results in the development of an artefact represented in the format of a model. The formulation of the model is accomplished by making use of the Design Science research guidelines for artefact development. Part of the process required that the artefact be refined through the use of an Expert Review Process. This involved an iterative (three phase) process which required (seven) experts from the fields of privacy, information security, and health care to respond to semi-structured questions administered with an interview guide. The data analysis process utilised the ISO/IEC 29100:2011(E) standard on privacy as a means to assign thematic codes to the responses, which were then analysed. The proposed information privacy model was discussed in relation to the compliance requirements of the South African Protection of Personal Information (PoPI) Bill of 2009 and their application in a primary health care facility. The proposed information privacy model provides a holistic view of privacy management that can residually be used to increase awareness associated with the compliance requirements of using patient PII.

  • Description: Organisations face increasing economic pressures from local and global competitors because of changing and increasing customer demands. Demands include improved product quality, flexibility, increasing price competitiveness and attaining higher levels of customer satisfaction. Businesses must have strategic and operational plans in place to combat these pressures to remain competitive. The South African automotive component manufacturing industry is particularly susceptible to such factors. The nature of the industry further lends itself to attracting high levels of political and economic attention, as it is an important contributor to economic growth. Harsh economic conditions pose problems in supply, internal supply and distribution and force organisations to be resourceful to survive. Ninety percent of the world’s information was generated within the last two years, a figure that equates to 2.5 quintillion bytes per day. The proliferation of data sources and the fine level of granularity at which this data is collected, present organisations with new challenges to benefit from this information. Market volatility presents shorter windows of opportunity and demands an unprecedented level of agility from the organisation. Delays in decision making, which is becoming more complicated and complex, cannot be tolerated. Advances in Technology have made it possible and affordable to store vast volumes of data; data that can be manipulated and transformed by any number of technology tools. Business intelligence (BI) provides valuable information to management and decision makers by reducing the latency between business events and the ability to report and act on prior events. This treatise will investigate the business intelligence systems of an automotive component manufacturing company and propose a model to improve BI utilisation. The true name of the company that will be researched will not be disclosed for confidentiality reasons, instead it will be called My Company. Research consists of a preliminary study to identify the problems in the business intelligence system within My Company. Literature reviews of critical success factors for business intelligence systems, maturity models, and characteristics of integrated business intelligence systems, will lead to the development of a proposed integrated business intelligence systems model to improve the current situation at My Company. The major findings of this research are presented as deliverables within each chapter and contribute to the development of the integrated BI systems model for automotive component manufacturing organisations. The major findings are: a list of critical success factors of BI from literature; list identifying gaps between the literature reviewed and the problems identified from the preliminary study conducted; selection of the HP (2009) maturity model as a preferred tool to be incorporated into the proposed model; the evaluation of the proposed integrated BI systems model by means of a case study; and the updated integrated BI systems model.

  • Description: The desire for heroes is a global and cultural phenomenon that gives a view into society’s very heart. There is no better example of this truism than that of the superhero. Typically, Superheroes, with their affiliation to values and morality, and the notion of the grand narratives, should not fit well into postmodernist theory. However, at the very core of the superhero narrative is the ideal of an individual creating his/her own form of morality, and thus dispensing justice as the individual sees fit in resistance to metanarrative’s authoritarian and restrictive paradigms. This research will explore Superhero comic books, films, videogames and the characters Superman, Spider-Man and Batman through the postmodernist conceptions of power, plurality, and morality.

  • Description: The purpose of this study was to develop an intervention health promotion programme to prevent circumcision related health problem such as sepsis, botched circumcision, dehydration, penile amputation and reduce the number of deaths. The intervention programme was aimed at promoting a safe male circumcision practice affecting boys aged 12-18 years at Libode rural communities in Eastern Cape Province of South Africa. This was achieved through a mixed method design using both quantitative and qualitative approaches utilizing sequential transformative strategy to allow for the convergence of multiple perspectives of the traditional male circumcision in Libode. The study was conducted in 22 schools of the rural communities of Libode because most of the participants are still attending school. Frequencies and percentages were used to analyse the quantitative data, utilizing the Statistical Package for Social Sciences (SPSS). A total of 1036 participants, AmaXhosa circumcised young men (abafana) and uncircumcised boys (amakhwenkwe) participated in the cross-sectional survey, quantitative phase of the study. Qualitative phase of this study was composed of 7 focus group discussions with a total of 84 circumcised and uncircumcised male participants and 10 key informants’ interviews were conducted. In analysis qualitative data, the researcher found the most descriptive words for each topic and turned them into categories or sub-themes. Topics that related to each other were then grouped in order to reduce the number of categories and to create themes. The similar categories of data were grouped and analysed using Tesch’s method. Findings indicated that traditional circumcision is performed during winter and summer holidays in order to cater for the boys who are attending schools. The circumcision age at Libode ranges from 12 and 18 years of age which is against the Health Standards in Traditional Circumcision Act (Act No. 6 of 2001). Although the participants were aware of the complications of male circumcision in Libode, there was a high preference for traditional circumcision (92.3% of participants) to hospital circumcision. The participants were of the view that the benefits of traditional circumcision outweigh the complications or challenges related to traditional circumcision. They wanted to be socially accepted and wanted to learn about manhood values in the traditional circumcision which are values that cannot be achieved through the hospital based circumcision. As male circumcision initiation is seasonal and the intervention programme needed to be approved by different stakeholders, the testing of intervention programme could not happen before the programme was approved by all the stakeholders.

  • Description: African sharptooth catfish Clarias gariepinus has become established as a non-native invasive species in Eastern Cape, South Africa, where it was translocated primarily through an inter-basin water transfer scheme into the Great Fish and Sundays rivers. This study examined the patterns in catfish distribution and abundance, and compared trophic niches in relation to the ichthyofauna of the two rivers. Correspondence analysis revealed upstream to downstream gradients associated with the spatial distribution in species richness for most species within the mainstream and mainstream to tributary gradients that were associated mostly with the spatial distribution of native minnows in both rivers. Catfish was predicted to occur widely within the mainstream habitats and to decrease progressively from mainstreams to tributaries. Based on classification and regression trees, the physico-chemical environment was found to be a good proxy for predicting the occurrence and abundance of catfish. Although non-significant relationships were observed between catfish and other native fish species abundances, the study suggests potential impact due to predation and interference in habitats where the invader co-occurs with other fishes. Comparisons of trophic niches indicated higher trophic diversity for the mainstream ichthyofauna than the tributary communities in both rivers, suggesting an upstream to downstream continuum in community structure and resource availability. Catfish within the invaded mainstream had comparable trophic niches and similar dispersion patterns among individuals for both rivers, but indicated differences in shapes of scatter. This suggests that the catfish exhibited a differential response, probably in relation to resource availability, that may be indicative of its dietary plasticity. The study suggests the proliferation of catfish and its probable impact within the mainstream flow-altered habitats where invasion resistance was possibly reduced. Comparisons of trophic niches provided information on its probable impact at different scales and the potential risk of invasion of tributaries inhabited by native minnow species.

  • Description: The study investigated the underachievement of Junior Secondary School learners within Ngqamakhwe district in the Eastern Cape Province. The research was conducted from the seven selected junior secondary schools in the Ngqamakhwe sub-district. The primary respondents of the study were one hundred and five (105) learners, forty two (42) educators and seven (7) school principals. Questionnaires were used to collect data. Three different questionnaires were designed, one for learners, one for educators and one for school principals. School schedules were also used to assess the extent of underachievement. The study utilised a quantitative research for the analysis of the data. The analysis was done using SPSS (Statistical Package for Social Sciences, version 19). The study revealed a number of factors responsible for underachievement amongst the learners. These factors were grouped into school and home environments. With the home environmental factors the level of education of parents and whether the parents buy reading material were more significant. With the school environment the age and grade of a learner were significant. Responses from principals and educators were regarded as factors underlying the underachievement and in particular the lack of resources both at home and at school. School principals of the seven schools revealed that there were no libraries, science laboratories, computers or clerks in their schools. Poverty emerged as one of the causes of underachievement. The influence of these may be statistically weak but are nonetheless present. A few other factors were noted to have statistically weak influences on the academic underachievement of learners. These included factors like gender, the parents’ employment status, the availability of a person to assist with homework, the frequency of parents visiting schools, whether television is available at home and whether the children are bored or not.From the findings the following recommendations were made:Creation of jobs by the government; Adult Basic Education must be encouraged in the rural areas; Employment of more educators; Appointment of clerks in every school; Building enough classrooms; Building libraries; Building of science laboratories; Review of teaching methods by educators.

  • Description: Driver fatigue is a complex phenomenon that has a range of causal factors including sleeprelated and task-related factors. These manifest as different safety and performance outcomes. Extensive research has been applied to linking these factors to performance impairment. However, little research focuses on the mechanisms by which this link exists. This research project therefore focuses on the processes underlying how driving performance is controlled and maintained during the development on non-sleep-related driver fatigue. The main aim was to establish whether progressive impairment of driving control over a prolonged drive could be attributed to a depletion of attentional resources, as proposed by Resource Theory, or to a withdrawal of effort, as proposed by Effort-Regulation Theory. As a multicomponent skill, driving requires perception, cognition and motor output. The secondary aim of this research was therefore to assess whether a prolonged drive impairs stage-specific information processing. Participants (n=24) in three experimental groups performed a 90-minute simulated drive wherein they were expected to keep the bonnet of a car on a lane (tracking task). The three groups differed in terms of lane width: small, medium and large, corresponding to low, medium, and high task-demand, respectively. To assess the impacts of this task on stagespecific information processing, participants performed a set of resource specific tests before and after the prolonged drive. Each task had two difficulty variations to ensure that performance decrement was due not only to the task-characteristic, but specifically to resource depletion. The tests probing information processing were: a modified Fitts' tapping task for motor programming, a digit recall task for perception, and an object recognition reading task for cognition. Performance was measured as lateral deviation of the car. Physiological measures included heart rate frequency (HR) and various time- and frequencydomain heart rate variability (HRV) parameters, eye blink frequency and duration. The Borg CR-10 scale was used to evaluate subjective effort and fatigue during the task. Driving control declined over time and was supplemented by HR, HRV, blink frequency and duration, indicating an increase in parasympathetic activity (or a reduction in arousal). An increase in blink frequency was considered as a sign of withdrawal of attentional resources over time. Driving control declined to a greater extent in the large road width group and reflected a lower parasympathetic activity, whereas the inverse was observed for the small road width group. Resource tests reveal a non-specific impairment of information processing following the prolonged drive. However, this was accompanied by an increase in parasympathetic activity. Overall, results indicate that Effort-Regulation Theory better accounts for the impairment of driving control in prolonged driving than does Resource Theory. This suggests that the impact of fatigue is guided more by task goals and intrinsic motivation than by the manner in which the fatigue state developed. Moreover, performance impairment by effort-regulation is dependant more on time on task than on task-demand

  • Description: The integration of learners’ prior everyday knowledge and experiences during teaching and learning is a pre-requisite in the Namibian curriculum. The curriculum states that if learners are taught in a way which builds on what they already know and they relate new knowledge to the reality around them, their learning in school can be made more meaningful. Thus, learners’ meaning making in the topic on nutrition was researched to find out whether elicitation and integration of learners’ prior everyday knowledge and experience in the nutrition topic enhanced or constrained their learning. This study was conducted with my grade10 learners at the school where I am currently teaching. The school is located in a rural area in Oshana region in Northern Namibia. This study is situated within an interpretive paradigm. Within the interpretive paradigm a qualitative case study approach was adopted. I considered this methodological orientation appropriate in this study as it allowed me to use the following methods: document analysis, brainstorming and discussion, semi-structured interviews and a focus group interview, practical activities with worksheets and observation and reflection. Multiple methods to gather data were used for triangulation and validation purposes. For data analysis purposes, the data sets were colour coded to derive themes and analytical statements. Ethical consideration was also taken seriously in this study. The findings from this study revealed that integration of learners’ prior everyday knowledge and experience enabled learners to understand science better particularly in the topic of nutrition. The study also revealed that learners possess a lot of prior everyday knowledge and experience about food they eat in their homes. However, data from the community members revealed that there are some contradictions between learners’ prior everyday knowledge and the science content of the topic. Nonetheless, engaging learners in practical activities in the testing of food (local and conventional western type foods) helped them to make meaning of the content learned. I therefore, recommend that learners’ prior everyday knowledge and experiences should be incorporated during teaching and learning of the topic on nutrition. The study also recommends that the Department of Education should ensure that teachers get the necessary support and training on how to integrate learners’ prior everyday knowledge and experiences.

  • Description: The main goal of this study was to investigate how grade 9 learners make sense of prior everyday knowledge and practical learning through exploring tooth decay problems in their local context. The study was conducted at a deep rural Junior Secondary School situated in Onangalo Village, Tsandi constituency in Omusati political region, northern part of Namibia. My research was triggered by the transformation in the Namibian curriculum, which now recognizes a need to contextualize science and make it relevant to the learners’ everyday life experiences. An interpretivist paradigm informed this study. Within this paradigm, a qualitative case study approach was employed. The unit of analysis was the various activities undertaken by my grade 9 learners with a view to make meaning of prior everyday knowledge and practical investigations in chemistry. A variety of data generating techniques were used in this study, namely, brainstorming and discussion sessions, questionnaires, practical activities with worksheets and semi-structured interviews. A video recorder was used to capture events throughout. Analytical categories emerged as a result of a coding system called pawing. From the analytical categories, analytical statements were formulated. The generated data was validated by a critical friend who was a Life Science teacher at the same school at which I did this study. Further validation was done through learners watching the video recordings and through focus group interviews. Methodological triangulation was also used to validate the data. The study revealed that the use of learners’ prior everyday knowledge and experiences in teaching and learning promoted active learners’ participation and enhanced meaning making. Thus, the study recommends the adoption of well-structured science lessons which take into consideration learners’ prior everyday knowledge. The study recommends that these science lessons be used in conjunction with practical activities to promote active learner engagement and conceptual development. Despite the benefits of integrating learners’ prior everyday knowledge during teaching and learning, the study however also revealed some challenges such as limited time and difficulties of English language proficiency amongst learners.

  • Description: One of the purposes of the Namibian curriculum is to ensure cultural inclusivity. That is, it recognises the inclusion of traditional cultural practices and experiences in science lessons where appropriate. Based on my experiences both as a learner and a science teacher, I have noted there is a rapid decline and loss of values in most of our cultural practices and heritages. This triggered my interests to do a study on an Oshiwambo traditional beverage known as Ombike. This study is therefore aimed at enhancing conceptual development, meaning making and understanding of concepts in fermentation and distillation. This study was conducted with my grade 9 learners at a school where I was teaching in Omusati region of Namibia. A community member who served as an expert was also a participant. She was involved more in discussions, interviews and most importantly in showing and demonstrating to the learners how Ombike is made practically. Essentially, the goal of this study was to investigate how the indigenous practice associated with the making of Ombike can be used to support meaning making of fermentation and distillation processes. This research is located within an interpretive paradigm where a qualitative case study was adopted. I consider this methodological framework appropriate in this study because it allowed me to use the following data gathering methods: brainstorming and discussion, observation, semi-structured and focus group interviews, and practical activities worksheet. Multiple methods were used for the purpose of triangulation and validation. An inductive analysis was used to discover data patterns and themes from the data. Moreover, ethical considerations were also taken seriously and all the participants gave informed consent. The findings of the study revealed that brainstorming and discussions were an appropriate strategy in eliciting learners’ prior everyday knowledge and experiences on, in particular, the making of Ombike. Furthermore, learner engagement and conceptual development were enhanced. This suggests that contextualisation of knowledge can enhance meaningful learning if it is properly planned. It was also found that practical activities in conjunction with mind maps helped learners to make meanings of scientific concepts. Based on my research findings, I therefore recommend the following three aspects: the consideration of learners` prior knowledge and experiences; contextualising knowledge through use of indigenous knowledge; and the learners’ active involvement in practical activities with an emphasis on key scientific concepts to be developed. That is, there is a need to teach for conceptual understanding.
