According to the South African White Paper 5 on Early Childhood Development (ECD), the initiative of the Department of Education (DoE), whereby grade R is being implemented as part of compulsory education, is directed at the poorest of the poor. Grade R teachers responsible for the education of 5/6 year old learners will therefore have to possess knowledge and skills to enable them to lead grade R learners from deprived circumstances to optimal development and learning readiness. For under-or unqualified Foundation Phase teachers who work and live in rural areas, distance learning is often the only option for professional development and concurrent increase in compensation. The School of Continuing Teacher Education of the North-West University designed an open distance learning model to provide in the educational needs of under and unqualified teachers. The Foundation Phase Curriculum within the Professional Educator Development programme of the Advanced Certificate in Education presented by the North West University (hereafter referred to as the NWU Foundation Phase ACE programme) is delivered via open distance learning. The National Curriculum Statements (Grade R-9) include grade R to three in the Foundation Phase Curriculum and therefore the NWU Foundation Phase ACE programme will be a financially viable option to train a large number of grade R teachers to provide in the need for qualified grade R teachers. This study investigates the way in which the NWU Foundation Phase ACE programme enables grade R teaching competency as programme outcome. To attain the research aims of the study a literature and empirical study were performed. The research aims of the literature study include the establishment of the knowledge, skills and attitudes to be included in a training programme with the aim of capacitating grade R teachers to facilitate the optimal development of five/six year olds from deprived circumstances. The literature is further researched to determine national and international criteria for effective design and content for training programmes for teachers of 5/6 year old learners. Through the literature study the criteria for effective training programmes for grade R teachers are determined and more specific the criteria for the effective implementation of distance learning for the training of grade R teachers. A comparative study between the NWU Foundation Phase ACE programme and similar distance learning programmes implemented internationally also serves as benchmarking for the evaluation of the NWU Foundation Phase ACE programme. Findings from the literature study serves as benchmark for the evaluation of the NWU Foundation Phase ACE programme and for the designing of questionnaires as measurement instruments for the empirical study. The empirical research has as its first aim to determine how the NWU Foundation Phase ACE programme provides grade R teacher-students the opportunity to develop the necessary knowledge, skills and attitudes to facilitate the optimal development and learning readiness of five/six year olds from deprived circumstances. Secondly the empirical study aims to determine how the design and content of the NWU Foundation Phase ACE programme accommodates the profile and educational needs of the target population namely the teacher who will be responsible for the education of five/six year old learners from deprived circumstances. Although a combination of both qualitative and quantitative statistical methods is used in the empirical study, this evaluation research is primarily seen as a quantitative study grounded in the post-positivist epistemology. The mixed method serves as verification of findings on the data. Empirical data were captured by means of questionnaires comprising structured and open questions. Data captured through structured questions were statistically analysed Iwhile responses in open questions were interpreted qualitatively by the researcher. Data triangulation serves as verification of findings as the researcher gathered data from three study populations namely the NWU Foundation Phase ACE teacher-students, the facilitators who facilitate the NWU Foundation Phase ACE programme at the various contact centres countrywide as well as lecturers presenting a similar Foundation Phase ACE programme at other tertiary institutions in the country. A comparison of responses from the structured questions and open questions with data from related literature further provides for methodological triangulation and verification of findings. Data from the literature study as well as from all three study populations in the empirical investigation converged regarding inadequacies in the way the design and content of the NWU Foundation Phase ACE programme enable the development of grade R teaching competencies as outcome. Deficiencies were identified in the way the programme accommodates the situated and personal circumstances of the teacher student. The opportunity provided by programme design and content for an inexperienced grade R teacher-student to develop grade R knowledge and skills through experience learning, social learning and learning through reflection within the grade R teaching and learning context, was also found to be lacking. Recommendations based on the findings are made for consideration of future programme design. / Thesis (M.Ed.)--North-West University, Potchefstroom Campus, 2010.

South Africa is a semi arid country in which the average rainfall of 450mm/year is well below the world average of about 860mm/year. As a result, South Africa’s water resources are scarce in global terms and limited in extent. Current predictions are that demand will outstrip water availability in the next 15 years. A coordinated approach to improve both water quality and quantity is needed and in order to achieve that, it is crucial to strengthen capacities of local community involvement in identifying the problems that affect them and strategies to solve them. This research was undertaken to develop a deeper understanding of community learning processes in integrated water resources management (IWRM) practices. The study drew on situated and social learning theory which explains that knowledge and skills are learned and embedded in the contexts in which knowledge is obtained and applied in everyday situations. Multiple data collection techniques were used within a case study design and included document analysis, interviews, focus group discussions and field observations. Data analysis was done in three phases and involved uncovering patterns and trends in the data sets. In this context I discovered, through careful observation and interviews with members of the different communities of practice, that people are learning through social learning interactions with other community members as they engage in their daily water management and food production practices. Learning interactions take place through both informal and formal processes such as meetings, training workshops, conversations and interactions with outsiders. I also discovered that people learn from ‘external groups’ or training programmes which bring new knowledge and expertise, but this needs to be contextualised in the local communities of practice. The research has also shown that there are a number of challenges that appear to exist in these learning contexts. For instance it was found that participation and social learning processes and interactions are influenced by a range of causal mechanisms that are contextual. These insights into how communities learn, as well as the tensions and difficulties that are experienced in the learning processes are important for furthering learning and participation in community-based IWRM practices, projects and programmes.

Stewardship in South Africa, as it is being implemented within the framework of the Biodiversity Stewardship Programme (BSP), is an attempt by conservation agencies to engage landowners in the voluntary securing of parcels of biodiverse land, through signing a contract for a certain time period, not to develop the landscape in ways that will impact negatively on the biodiversity of the area in question. The focus of this study is the relationship between biodiversity stewardship and social learning, as I hope to ascertain how stewardship practices are helping to resolve the current problems of biodiversity loss in the Western Cape. The overall aim of this research is to gain an understanding of how, in its capacity as a conservation education process, the Cape Nature Stewardship Programme can foster social learning amongst the landowners involved in its implementation, by leading them to a better understanding of their environmental responsibilities. Data was generated through the use of interviews and informal discussions with participants together with document analysis, such as brochures, pamphlets and presentations. My approach to the analysis of my data was two-phased. In the first phase, I analysed the data generated from the interview process and from reviewing the documents the stewardship officials supplied me with. The second phase involved looking into the results of the two case studies, and formulating analytical statements which were then used to review the case evidence within a social learning perspective, derived from Wals (2007). In constructing an analytical framework for the interpretation of my data, I drew heavily on Wals' (2007) notion of social learning occurring in sequential activities. I used this insight as a lens through which to trace the educational effects of the implementation of the CNSP in the two case study areas.The research highlighted evidence that Stewardship initiatives should be based on the foundation of social learning and invest time and effort in building an environmental knowledge capital amongst the landowners involved. By equipping them with these necessary conservation skills, one creates a 'community of practice' where those individuals adopt a sustainability habitus contributing towards a change and environmental understanding and practises in field.

Text in Afrikaans / In the light of two literature studies, the nature, origin and consequences of early perceptions of marriage, the form of identities and frames of reference, as well as the resultant origin of an internalized marriage have been explored. An empirical survey was undertaken, with the aid of a specially formulated questionnaire, to investigate the influence of early perceptions of marriage, and thus marriage expectations, on a person's own marriage. The research outcomes show that children do internalize aspects of their parents' marriage and transfer these to their own marriage. There seems to be an important similarity between pattern of communication and conflict management in the original family of questioned subjects and their marriage. Although some subjects have denied the influence of their original family on their marriage, there seems to be a transfer of patterns nevertheless. / Educational studies / M.Ed.(Voorligting)

South Africa is currently experiencing rapid social change with socio-economic deprivation, influencing the future orientation of adolescents. Research indicates that a lack of future expectations affects present behaviour−diminishing the possibility of socialisation and productivity in adulthood. The objective of this study is to assess the future perceptions of indigent adolescents. The Gestalt paradigm provided the framework for defining the study. This empirical study uses a mixed methodology design combining both the quantitative and the qualitative approaches. A crosssectional survey provided the groundwork in terms of ascertaining the degree of awareness in respect of the future orientation of indigent, urban adolescents whilst a qualitative, semi-structured, one-on-one interview provided an in-depth contextualisation of the problem. The empirical study demonstrated that, although socio-economic deprivations and pervasive social issues do influence the future orientation of adolescents in South Africa, these influences have not eradicated the indigent adolescents’ motivational striving toward a positive and productive future. / Social Work / M.

La cognition physique correspond à l’ensemble des connaissances que nous possédons sur les objets inanimés qui nous entourent, et à leurs relations avec l’environnement. Selon l’hypothèse de l’intelligence sociale générale, la cognition physique se serait développée tel un continuum (à l’instar de tous les autres domaines cognitifs), chez les espèces vivant au sein de groupes sociaux complexes. A l’inverse, l’hypothèse de l’intelligence sociale adaptée suppose que le fait d’interagir avec des congénères a permis de développer des capacités cognitives supérieures, mais spécifiques, du domaine social. Bien que les recherches relatives à l’évolution de la cognition physique se soient d’abord focalisées sur les primates, nous savons aujourd’hui que certains oiseaux sont capables d’interagir de manière complexe avec leur monde physique, en utilisant et en fabriquant des outils (p. ex., voir Article 1). Néanmoins, de nombreuses familles aviaires restent à ce jour non étudiées, laissant ce débat en suspens. L’objectif général de ce travail de recherche est de contribuer à une meilleure compréhension des facteurs responsables de l’évolution de la cognition, grâce à l’apport théorique de l’hypothèse de l’intelligence sociale suivant son aspect général et adapté. Quatre espèces, jusqu’alors inconnues sur le plan cognitif, ont été sélectionnées suivant leur degré de socialité mais également la spécificité de leur écologie. Ce dernier facteur, trop souvent ignoré en biologie du comportement, est crucial pour apprécier le comportement dans son ensemble. Nous avons ainsi estimé la faculté des sujets, à savoir des pélicans blancs Pelecanus onocrotalus (sociaux) et des euplectes vorabés Euplectes afer afer (grégaires), à reproduire le comportement d’un congénère (domaine social) grâce à un test d’apprentissage social (Articles 2 part I & 3). Nous avons ensuite évalué leur capacité à se servir d’un objet pour obtenir une récompense alimentaire hors de portée (domaine physique), grâce à un test d’utilisation d’outils (Articles 2 part II & 4). Bien que les pélicans fussent capables de résoudre rapidement la tâche d’apprentissage social, ils ne réussirent pas à utiliser spontanément des outils (cf. discussion Article 2 part II). A l’instar du pélican, l’euplecte imita le comportement d’un congénère. Néanmoins, il échoua à utiliser des outils dans le contexte du fourragement, malgré le fait que cet oiseau utilise et fabrique des outils de manière complexe pour construire son nid.A défaut d’avoir pu étudier l’apprentissage social et l’utilisation d’outils chez deux autres espèces sociales, les calaos terrestres Bucorvus et les toucans Ramphastidae, cette recherche consistait également à administrer un paradigme permettant d’apprécier le domaine physique : le test de la ficelle (Articles 5 & 6, respectivement). La tâche impliquait de tirer sur une ficelle afin d’obtenir une récompense alimentaire accrochée à son extrémité. Les calaos terrestres échouèrent à tirer sur la ficelle dans la configuration verticale, mais réussirent rapidement la tâche dans diverses conditions de la configuration horizontale. Chez les toucans, cependant, un seul sujet réussit le test dans sa configuration verticale. Les résultats obtenus nous permettent de réfuter l’hypothèse de l’intelligence sociale dans son aspect général. En effet, aucun lien ne semble se dessiner entre le domaine social et physique chez les quatre espèces aviaires étudiées. Bien que l’hypothèse de l’intelligence sociale soit soutenue depuis plus de quatre décennies, une théorie unitaire est requise. Dans ce cadre, un nouveau modèle d’évolution cognitive, permettant d’évaluer l’importance de l’intelligence générale chez une espèce donnée, pourrait s’avérer particulièrement prometteur. / Physical cognition is defined as the knowledge that we possess about the inanimate objects surrounding us, and their relation with the environment. According to the general social intelligence hypothesis, physical cognition would have developed as a continuum (like all the other cognitive domains), in species living in complex social groups. By contrast, the adapted social intelligence hypothesis assumes that interacting with conspecifics has allowed development of superior, but specific, cognitive capacities related to the social realm. Although research on the evolution of cognition first focused on primates, we now know that some avian species are capable of interacting with their physical world in a complex way by using and manufacturing tools (e.g., Article 1). However, to date, various bird families are still unstudied, leaving open this debate. The general goal of this work is to contribute to a better understanding of the factors acting on the evolution of cognition, thanks to the theoretical input of the social intelligence hypothesis according to its general and adapted aspect. Four species that had never been studied in cognitive studies before were selected according to their degree of sociality but also according to the specificity of their ecology. This latter factor has been largely ignored in behavioural biology, although it is crucial for a more holistic comprehension of the behaviour. This work aimed to assess the ability of two avian species, great white pelicans Pelecanus onocrotalus (social birds) and yellow-crowned bishops Euplectes afer afer (gregarious birds), to imitate the behaviour of a trained conspecific (social domain) with a social learning task (Articles 2 part I & 3, respectively). Subsequently, we have studied heir ability to use an object in order to get an out-of-reach food reward (physical domain) with a tool use task (Articles 2 part II & 4). Although pelicans were capable of rapidly solving the social learning task, they did not succeed in using tools spontaneously (cf. discussion Article 2 part II). The bishops were able to imitate the behaviour of a conspecific, however they were not capable of using tools in the foraging context, although these birds are well known to use and manufacture tools in quite a complex way in order to build their nests. We have also administrated to two other avian social species, ground-hornbills Bucorvus and toucans Ramphastidae, an experimental paradigm to assess cognition in the physical domain: the string-pulling test (Articles 5 & 6, respectively). The task involved pulling on a string in order to obtain a food reward attached to its extremity. Ground-hornbills failed to pull on the string in the vertical configuration, but rapidly solved the task in various conditions within the horizontal configuration. In toucans, however, only one subject succeeded in the vertical configuration. These results allow us to refute the social intelligence hypothesis in its general aspect. Indeed, no link seems to be drawn between the social and the physical domains in the four species studied. Although the social intelligence hypothesis is supported since decades, a unitary theory is required. A new model of cognitive evolution, that allows assessing the importance of general intelligence in species, may be particularly promising.

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

Communication seems to play a pivotal role in any high school classroom. But it was found those classes or certain individual students shy away from engaging in effective communication during natural science lessons in Swaziland. One of the directives in the Swaziland National Education Policy states that syllabuses for studies in Form 4 and 5 should enable learners to develop essential skills which include communication and language skills. This study then, on realising that there was a gap between what was stated in the Education Policy and what was actually the case in the natural science classrooms, sought for a solution that would encourage effective communication in natural sciences. Therefore, the main purpose of the study was to encourage active participation of high school students in natural science lessons. The main research question posed for this purpose was: Can student motivation enhance classroom discourse for the negotiation of science understanding? Five sub-questions emanated from the main research question: (a) How does classroom discourse relate to natural science understanding? (b) What effect does external motivation have on discourse during natural science lessons? (c) What is the effect of feedback during natural science learning? (d) How can feedback be enhanced in the natural science class? (e) Which teaching strategies improve interactions during natural science learning? The study is organised into five chapters. The first chapter summarises the whole study by giving the problem statement, research aim and objectives, definition of terms, as well as chapter divisions. Chapter two provides the background to the study through the discussion of education theories based on classroom discourse and motivation. The third chapter presents detailed information about the research design, methods of data collection and analysis, as well as a proposed method for motivating students. The fourth chapter presents the research results, analysis and discussion. The fifth and the final chapter presents research findings, concluding remarks drawn from the research findings, as well as recommendations for similar future research. The case study style uses a qualitative, descriptive and exploratory approach. The study concentrated on theories explaining learning and motivation. The sample comprised six purposefully selected students and their two physical science teachers. Data were collected using the standardised open-ended interview and non-participant lesson observation methods, and from documents. The data were collected in two phases, the pre-motivation phase and the motivation phase. The collected data was further categorised into two segments, with each segment being a unit of analysis. One of the segments was composed of oral interchanges, while the other was composed of students’ written work. The data was then transcribed, coded, analysed and discussed using the thematic discourse analysis approach. The principles of triangulation, reliability and validity ensured the credibility of the study remained intact. Research ethics were also observed by the researcher and there was trust, respect and autonomy during data collection. The ethics observed included informed consent, confidentiality, beneficence, anonymity and non-malificence. Permission to collect data was sought and obtained from all concerned. The motivation method helped the physics group improve more (55%) than the chemistry group (7%) in tests. In the overall performance the two groups improved more or less the same: the chemistry group improved by 4% while the physics group improved by 5%. There were three main findings for the study and they revolved around the purpose and the research question. The first major finding was that the motivation method used with the students instilled self-discipline in the students, resulting in self-regulated behaviour and better understanding of science concepts. The finding suggested that motivated students are self-disciplined and take ownership of their learning. The second major finding was that during the motivation phase of data collection interactions improved between the students and their science teachers. These interactions were in the form of classroom talk, submission of school work and feedback. It was inferred that motivated students communicate more effectively and with better understanding of the concepts taught. The third major revelation was that the students were motivated by learner-centred teaching strategies and the use of teaching aids in a science laboratory. A main finding for the first sub-question was that the more students interacted with each other, with their natural science teachers, and with their books the more they appreciated and understood science concepts. For the second sub-question the main finding was, the motivation method used with the students improved discourse during natural science lessons. The marks the students were awarded gave them the energy to engage more in science activities and to behave well. The main finding for the third sub-question was that prompt feedback and positive comments motivated students to engage more in science discourse and to understand science concepts better. An important finding from the fourth sub-question was that prompt and positive feedback enhanced feedback, as well as giving students tasks that were not too far above their abilities, enhanced feedback in the natural science class. For the fifth sub-question it was found that student-centred teaching methods as well as teaching aids and learning in science laboratories improved interactions during natural science learning. / Curriculum and Instructional Studies / D.

Summaries in Engish and Afrikaans / The goal of this research is to evaluate whether a personal and social skills program can effectively be implemented by social workers in a prison. A control- and experimental group were used in a quasiexperimental design. The respondents were twenty-four white, male, sentenced prisoners in Pretoria Central Prison. The Heimler scale for social functioning and the Hudson-scale for family relations are the standard questionnaires, which were utilised to measure results during the pre-testing and post-testing phase. All twenty-four respondents completed the scales during the pre- and post-testing phase. The Wilcoxon t-test and Mann-Whitney U-test were used for statistical purposes. A computer was used to process data. Both measurement scales confirmed positive results. The independent variable, that is, the personal and social skills program had an effect in the desired direction on respondents in the experimental group. The Hudson-scale for interpersonal relationships, however, showed more dramatic results. The results for the control group, showed noticeable decline in both social functioning of the respondents as well as experience of family relationships. / Die doel van hierdie navorsing is om te bepaal of maatskaplike werkers in 'n gevangenis 'n persoonlike en sosiale vaardigheidsprogram effektief kan implementeer.
