Grade 12 learners in one Namibian secondary school participated in a study of science process skills implied in their International General Certificate of Secondary Education (IGCSE) physical science syllabus. The study aimed at finding out learners’ ability to identify science process skills in their physical science syllabus, criteria used to identify skills and whether any relationship existed between learners’ achievement in performing skills and learners’ ability in identifying the skills. Four physical science syllabus topics were taught. Learners performed and identified science process skills in learning and assessment tasks. A One Group Pretest-Posttest research design was used in a combined qualitative and quantitative research method. Data revealed that learners identified science process skills. Science processes performed during learning experiences were used as criteria to confirm presence of the skills. Learners’ achievement increased in performing and identifying science process skills after intervention activities. There seemed no relationship between learners’ achievement in performing and learners’ ability in identifying science process skills. / Science and Technology Education / M. Ed.

The changing role of literacy in primary education, with its emphasis on the acknowledgement of the learner’s values, beliefs, culture, background and language is the focus of this study. The research was concerned with understanding the literacy practices of Foundation Phase Grade 3 teachers who are able to intentionally promote and mediate literacy acquisition among their learners. A qualitative design was used to describe the approaches of effective literacy teachers. The research study discovered that while the teachers made use of a number of teaching methods that underpinned a de-contextualised and constructivist approach, a socio-cultural approach to literacy was lacking. The results call for a broadening of the definition of literacy; one that acknowledges the socio-cultural background of the learners in developing a literacy disposition that prepares learners for a changing world. / Educational Studies / M.

In the climate of poor student achievement and a lack of skilled teachers in natural science and mathematics, the main research question of this study was: How can the professional development of primary school teachers be managed by means of action research? The aim of the study was to develop, implement and evaluate a site-based collaboration programme to promote the professional development of the teachers in these subjects within a home-based or semi home-based teaching context. The theory of situated learning within a community of practice (CoP) was used as conceptual framework. Purposeful and convenient sampling was implemented to select participants. Five grade 4 teachers, five grade 5 teachers, four grade 6 teachers and eight members of the school management team participated in the three year study. During the planning phase a needs analysis was done. During the action phase, lead teachers were responsible for the planning in one or two subjects. The teachers met once every six school days (about 30 meetings per year), for up to two hours to discuss content and methodological issues, plan assessment strategies, analyse and reflect on results and decide on intervention strategies. The grade 4, 5 and 6 groups completed six, four and two action research cycles respectively, and the school management team six action research cycles of about six months each. To evaluate the professional development that resulted, data collection was by means of observation, field notes, typed minutes, four focus groups, 12 individual interviews, teachers’ files, a questionnaire and students’ books and achievements. The results indicate that the professional development of primary school teachers could be managed and constantly improved by means of action research. When school managers organise teachers into communities of practice and implement action research cycles, the teachers learn in a context-sensitive way. This learning is characterised by two social stages involving participation in the subject and grade CoP, and an independent stage of personal involvement when teachers internalise knowledge and practices of other teachers. The professional development of the teachers was in the areas of content knowledge, pedagogic content knowledge, assessment literacy and professional attitudes. Student achievement improved. / Educational Leadership and Management / D. Ed. (Education Management)

The purpose of this study was to investigate the impact of the training given to Foundation Phase (FP) teachers in the implementation of Curriculum and Assessment Policy Statement (CAPS), with the intention to develop an alternative professional development (PD) approach for this Phase. Literature indicates that the academic success of learners can be significantly affected by Foundation Phase teachers’ access and participation in quality PD activities. It also indicates that PD is much more than training. It includes on-going workshops, follow-up, study, reflections, observations and assessment which accommodates FP teachers as learners, recognises the long-term nature of learning, and utilises methods that are likely to lead teachers to improve their practice as professionals. In this study, mixed methods research approach was employed to collect empirical data. It includes questionnaires responded to by 84 FP teachers, three sets of interview questions, that is, one for 9 primary school principals, one for 3 subject advisors, and the last one for the Focus group made up of 10 FP teachers who were not included in questionnaires. Observation at training centre was also conducted. The study revealed that the responses from the five sets of data collection instruments seemed to agree on the following: - FP teachers were not involved in the design of their PD activities; - An appropriate time for FP teachers to engage in PD activities is during school holidays; - The length of the training was too short; - Training was not based on the teachers identified needs; and - It was not designed by teachers in cooperation with experts in the field. This study therefore recommends the use of mixed-models approach because the Cascade model that was used, is not addressing the needs of all FP teachers. / Educational Leadership and Management / D.

The aim of the study was to investigate the impact of expatriate school leaders in the education system of the United Arab Emirates (UAE). This study was motivated by a concern regarding the short-term entry of expatriates into the UAE education system, thereby questioning their overall impact in the UAE educational reform. The literature reviews focused on mentoring and leadership within education, and how these related to the UAE educational reform in particular. The empirical investigation used a qualitative, ethnographical case study design. The situated learning theory and the social constructivist theory were used as conceptual frameworks for the study. Purposive and convenient sampling was employed to select five indigenous and five expatriate school leaders as participants for this study. Qualitative data collection was preceded by a pilot study in which an indigenous and an expatriate school leaders were informally interviewed. Individual interviews were thereafter conducted whereby participants were interviewed over a two-week period. The interviews were followed by focus group sessions that were gender specific. Notes were kept and all observations were documented throughout the study. Findings were that, according to the participants’ views, expatriate school leaders seemed to make little impact on current UAE education reform. Their impact was inhibited by dubious motives of many expatriate school leaders working in the UAE; cultural and religious barriers between expatriate and indigenous school leaders; language as a barrier; lack of role modelling; continuous changes in the UAE education system; poor attitudes of some indigenous school leaders; resistance to change; lack of sustainability and poor communication between school leaders and policy makers. Recommendations were provided to enhance the impact of expatriate school leaders within the UAE system. Firstly, expatriate impact could be enhanced through an intensive two-week induction programme and secondly, by means of a partnership development framework to improve the mentoring relationship between expatriate and indigenous school leaders. Ways to overcome the language barrier were also recommended. Additionally, the study provided recommendations for further research. / Educational Leadership and Management / D. Ed.

Mathematics anxiety is a personal characteristic which is widespread and continuing. It has a debilitating effect on mathematics performance and contributes to perceptions and attitudes that perpetuate a dislike for mathematics and a lack of confidence when dealing with mathematical problems. An investigation of relevant literature on mathematics anxiety identifies sources and symptoms and emphasises a need for a comprehensive approach to remediation. The historical development of an appropriate measuring instrument is documented and statistical evidence is used to create a mathematics anxiety rating scale suitable for measuring anxiety levels of secondary school pupils and student teachers. The extensive literature interest, research publications and remedial programmes emphasise the problem of mathematics anxiety and thus the need for a comprehensive approach to remediation. Mathematics teaching and curriculum design is expounded to provide the necessary direction to the alleviation of mathematics anxiety. General perspectives on curriculum design are discussed and a cyclical systems approach is recommended. Elements of this approach are detailed and are linked to important personal characteristics to add a humanistic and socio-cultural view of curriculum design in mathematics. The didactic viability of constructivism as an approach to mathematics curriculum design is investigated. Constructivism embodies a philosophy and a methodology which addresses the critical aspects influencing mathematics anxiety. Classroom topics and activities are reviewed in terms of a constructivist approach and the sources of mathematics anxiety are discussed from a constructivist perspective. A longitudinal case study of pupils during their five years at secondary school as well as a study involving student teachers was undertaken. Mathematics performance, perceptions, attitudes and levels of anxiety were investigated by means of tests, questionnaires, and mathematics anxiety rating scales. The statistical results of this research provide evidence to support a comprehensive approach to the remediation of mathematics anxiety. Constructivism is seen as the synthesis of critical aspects of teaching and curriculum development which will stem the perpetuation of mathematics anxiety. Constructivism provides the didactic approach to develop each individual's intellectual autonomy and mathematics power, by instilling a problem solving attitude and a self-confidence when doing mathematics. / Curriculum and Instructional Studies / D.

The aim of this study was to investigate the comparative effects of Constructivist-Based Teaching Method (CBTM) and the Traditional Teaching Method (TTM) on Grade 11 Mathematics learners’ errors in algebra. The constructivist learning theory (CLT) was used to frame this study. Mainly, CLT was used to influence the design of CBTI to hone participants’ errors in algebra that militate against their performance in Mathematics. The study was conducted in the Mpumalanga Province of South Africa with a four-week intervention programme in each of the two participating secondary schools. Participants consisted of n=78 Grade 11 Mathematics learners and one Grade 11 Mathematics teacher. A non-equivalent control group design consisting of a pre-test and post-test measure was employed. The Grade 11 teacher in the control school employed the TTM while the researcher implemented CBTM in the experimental school. The main aspects of CBTM entailed participants’ construction of their own knowledge from the base of prior knowledge and through group learning approach and exploratory talk in which discussions included argumentation, verbalising explanations, justifications and reflections. Participants in experimental school became familiar with the basic principles of CBTI such as group work, which enhanced the construction of conceptual understanding of algebraic concepts. This reduced most of the errors they commit in algebra and elevated their performance in Mathematics. The principal instruments for data collection consisted of a standardised Algebra Concept Achievement Test and lesson observations. The pre-test was used to determine participants’ initial errors in algebra before the intervention. A post-test was given at the end of intervention to ascertain change in participants’ errors in algebra over a four-week intervention period. Using descriptive and inferential statistical techniques, the study found that participants in experimental school significantly reduced their errors in algebra than those in control school. The study showed that CBTM was a more effective pedagogy that improved the errors Grade 11 learners commit in algebra than the TTM. / College of Education / M. Ed. (Mathematics Education)

Large underfunded classrooms are indicative of the situation found in many developing countries. These limitations often lead to the ineffective teacher-centred approach dominating classroom instruction in these countries. The aim of the study was to examine active learning strategies used by teachers in large unfunded Physics classrooms, in Kerala, India. This study used a qualitative approach utilising a case study method. The data collection process involved mainly unstructured interviews, lesson observations and the analysis of documents. The results of the study indicate that despite the difficulties faced in India, similar to those faced by other developing countries, the Indian state of Kerala implements and supports active learning rather than the more common teacher-centred approach. The research defines the common forms of active learning in the Physics lessons and critically examines the core elements of the learner-centred teaching approaches. Successes have been found in the implementation of active, collaborative, cooperative and problem-based learning in the large underfunded Physics classes. The results of the research suggest that teachers need to be highly trained, resourceful, creative, hardworking and sometimes go above and beyond the required duties to make active learning in large underfunded Physics classroom a success. / Science and Technology Education / M.

South African schools have experienced a high rate of educator turnover which has led to greater school instability, disruption of curricular cohesiveness and a continual need to hire experienced and inexperienced educators, who may be typically less effective, as replacements for educators who leave. Unfortunately, principals of schools lack organizational capacity to provide the necessary management strategies that can enhance educators’ job satisfaction. Since the principals are fully responsible for the proper functioning of the schools and their personnel, this study explored the relationship between the management strategies of school principals and the educators’ job satisfaction levels within the context of South African schools. It examined how management strategies of principals impact on job satisfaction levels of educators in various school environments. The study explored literature from local and international perspectives on management strategies and the job satisfaction of educators. It described the background and findings of the relationship between management strategies of principals and educators’ job satisfaction levels from an education management perspective. For the empirical inquiry the study adopted a qualitative research paradigm, and as such, a qualitative investigation of the relationship between the management strategies of school principals and the educators’ job satisfaction levels in schools was conducted. Non-probability sampling methods were used to select a sample of six school principals and twelve educators. Individual and focus group interviews were used in data collection and were audio-recorded. Throughout the research study, ethical considerations were upheld. Data analysis involved a mix of content and thematic analysis instruments. The study findings determined the relationship between management strategies of principals and educators’ job satisfaction levels. An understanding of human relationship is very important to school principals who have the responsibility of establishing an environment that not only motivates educators, but can also help to enhance their job satisfaction levels in a positive way. An understanding of educators’ needs also helps school principals to devise management strategies to enhance the job satisfaction levels of educators. Based on the findings, recommendations to improve the management strategies of school principals in the enhancement of educators’ job satisfaction were proposed. / Educational Leadership and Management / D.

Cette recherche se caractérise, premièrement, par une discussion théorique sur le concept d'agent autonome, basée sur des éléments issus des paradigmes de l'Intelligence Artificielle Située et de l'Intelligence Artificielle Affective. Ensuite, cette thèse présente le problème de l'apprentissage de modèles du monde, en passant en revue la littérature concernant les travaux qui s'y rapportent. A partir de ces discussions, l'architecture CAES et le mécanisme CALM sont présentes. CAES (Coupled Agent-Environment System) constitue une architecture pour décrire des systèmes bases sur la dichotomie agent-environnement. Il définit l'agent et l'environnement comme deux systèmes partiellement ouverts, en couplage dynamique. Dans CAES, l'agent est compose de deux sous-systèmes, l'esprit et le corps, suivant les principes de la situativite et de la motivation intrinsèque. CALM (Constructivist Anticipatory Learning Mechanism) est un mécanisme d'apprentissage fonde sur l'approche constructiviste de l'Intelligence Artificielle. Il permet a un agent situe de construire un modèle du monde dans des environnements partiellement observables et partiellement déterministes, sous la forme d'un processus de décision markovien partiellement observable et factorise (FPOMDP). Le modèle du monde construit est ensuite utilise pour que l'agent puisse définir une politique d'action visant à améliorer sa propre performance / This research is characterized, first, by a theoretical discussion on the concept of autonomous agent, based on elements taken from the Situated AI and the Affective AI paradigms. Secondly, this thesis presents the problem of learning world models, providing a bibliographic review regarding some related works. From these discussions, the CAES architecture and the CALM mechanism are presented. The CAES (Coupled Agent-Environment System) is an architecture for describing systems based on the agent-environment dichotomy. It defines the agent and the environment as two partially open systems, in dynamic coupling. In CAES, the agent is composed of two sub-systems, mind and body, following the principles of situativity and intrinsic motivation. CALM (Constructivist Learning Anticipatory Mechanism) is based on the constructivist approach to Artificial Intelligence. It allows a situated agent to build a model of the world in environments partially deterministic and partially observable in the form of Partially Observable and Factored Markov Decision Process (FPOMDP). The model of the world is constructed and used for the agent to define a policy for action in order to improve its own performance
