- Description: This study was conducted in Grahamstown in the Eastern Cape, South Mrica. Triggered by the demands of South Mrican post-apartheid curriculum transformation, the study focused on establishing a sustainable science teachers' trans formative and continuous professional development (TTCPD) network with the view to improving their practice. It is premised on the assumption that teachers are capable of taking responsibility for their own professional development. It is a case study carried over a period offour years with a group of eight teachers. Rooted in the socially critical-emancipatory orientation in conjunction with the participatory action research approach, and located in the qualitative and interpretive research paradigms, it focuses on doing research in democratic and egalitarian ways through working with teachers rather than on them. Such a stance supposes a collaborative partnership and a dialogic relationship viewed as being both reciprocal and mutually enriching for the teachers who were seen as co-learners and co-researchers in this study. Two main goals of the study may be identified. For the first goal, the actors in this study established a sustainable and participative approach to professional development. This was explored through the formation of a TTCPD network which was informed by the actor-network theory framework. Our focus was on co-construction of scientific knowledge utilising the development and adaptation of learning and teaching support materials (LTSMs) as a catalyst to drive the process. The second goal was to examine how the TTCPD network enhanced the teachers' subject-content knowledge, pedagogical-content knowledge as well as individual and collaborative reflections. The research process evolved into three mam phases: The initial phase involved adapting and modifying LTSMs which were initially used in conjunction with microscale science kits and pilot tested with a group of Grade 10 students. This led to the second phase of the research project, which was aimed at gaining insights into the science teachers' capabilities in developing teaching and learning units of work. ii \ The second phase focused on the development of a collaborative orientation to the development of LTSMs and culminated in the formation of sub-networks responsible for certain tasks within the broader network. AB common ground, we focused on developing teaching and learning units of work on the following science topics: electrostatics, electricity, and electrochemistry, to illuminate and foster integration within science. The third phase was concerned with gaining insights into the science teachers' practice in their classrooms. This phase focused on putting theory into practice through the collaborative implementation of teaching and learning units of work. Feedback on the lessons was discussed during our workshops as an attempt to further enhance collaborative reflections. Data was generated usmg workshop discussions with reflective notes; active interviews; focus group discussions; co-teaching, participant observation and videotaped lessons with reflective notes; and a research journal. A variety of data generation techniques were employed to enhance validity and quality of the research. Techniques for validation and trustworthiness of data included triangulation; member checks orface validity; prolonged engagement; catalytic validity and peer validation. The study exposed the underlying historical, ideological and epistemological contradictions of the teachers' past educational backgrounds. It emerged that the ways in which they were taught were at times an inhibitor to innovativeness, perpetuating transmissive approaches to teaching and learning. Lack of professional development and support, and the tensions between policy formulation and implementation exacerbated this. Reflections from the teachers' experiences further revealed that, for teachers to be effective agents of change in the reform process, empowerment opportunities are vital. AB a result, exposure to the TTCPD network was useful in capacitating the teachers with the development of LTSMs, which led to the enhancement of their pedagogical, and science content knowledge conceptual development as well as collaborative reflections.The main findings of this study is that, science teachers' transformative and continuous professional development based on participative approaches and mutual collegial support are indispensable, and that teachers' socio-cultural contexts and experiences should be taken into consideration during this process. Teachers should be regarded as central in the process, and mutual respect and dialogical relationships are pivotal. A further recommendation of this study is that capacity-building is critical for quality teaching and learning, and there is a need to move beyond the rhetoric of complacency to pro-activism, supporting ongoing development of teachers in professional transformative networks. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The objective of this study was to understand how teacher educators in a Namibian college of education interpret and practice the learner-centred pedagogy underpinning the Basic Education Teachers Diploma (BETD) program. In order to achieve this objective, a case study approach was adopted, qualitative-interpretive in orientation and drawing upon interviews, naturalistic non-participant observation and document analysis. Bernstein's theory of pedagogy - in particular his notion ofrecontextualization - offered ideas and concepts that were used to generate and analyse data. The data indicated that, at the level of description, teacher educators interpreted leamercentred pedagogy as a pedagogic practice based on weak rules of regulative discourse, or a weak power relation between themselves and their student teachers. The weakening of the rules of regulative discourse and the waning of educator authority were indicated in the interview narratives, which evoked a pedagogic context characterized by a repositioning of the student teacher from the margins to the centre of the classroom, where he or she enjoyed a more active and visible pedagogic position. Contrary to the dis empowering dynamic within classroom practice under the apartheid dispensation, the repositioning of the student teacher suggested a shift of power towards him or her. Similarly, the identification of the teacher educator as afacilitator, which featured prominently in the interview narratives, further suggested a weakening or diminishing of the pedagogic authority of the teacher educator. With regard to rules pertaining to the instructional discourse, the data revealed an interpretation of leamer-centred pedagogy as a pedagogic practice based on strong framing over the selection of discourses, weak framing over pacing, and strong framing over sequencing and criteria for evaluation. When correlated with the interview data, the data generated through lesson observation and teacher educator prepared documents such as lesson plans revealed a disjuncture between teacher educators' ideas about leamer-centred pedagogy and their practice of it. Contrary to the interviews, lesson observation data revealed that teacher educators implemented leamer-centred pedagogy as a pedagogic practice based on strong internal framing over rules of the regulative discourse. Data further indicated strong internal framing over the selection, sequencing, pacing and evaluation. The study concluded that while some teacher educators could produce an accurate interpretation oflearner-centred pedagogy at the level of description, most of them did not do so at the level of practice. Findings revealed structural and personal-psychological factors that constrained teacher educators' recontextualization of the new pedagogy. A narrow understanding of leamercentred pedagogy that concentrated only on changing teacher educators' pedagogical approaches from teacher-centred to learner-centred, while ignoring structural and systematic factors, tended to dominate not only the interview narratives but also official texts. Learner-centred pedagogy was understood as a matter of changing from teachercentredness to leamer-centredness while frame factors, for instance regarding the selection, pacing or sequencing of discourses, still followed the traditional approach. The study recommends the adoption of a systematic and deliberate approach to address the multiplicity of factors involved in enabling teacher educators to interpret and implement leamer-centred pedagogy at the micro-level of their classrooms. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The study sets out to examine the television coverage of the 2002 presidential campaign in Zimbabwe by examining the extent to which the Zimbabwe Broadcasting Corporation fulfilled the mandate of public service broadcasting. The primary objective of this study is to assess how ZBC television newscasts mediated pluralistic politics in the coverage of the country's presidential election campaign, in line with the normative public sphere principles. The thesis comprises seven chapters organized, first, with an introductory chapter, which provides the general background of the study. The chapter offers the rationale for the focus on TV rather than other media fomls . There are two theoretical and contextual chapters in which the use of both qualitative and quantitative methods is explained and findings are presented. Finally, the conclusion offers recommendations about the form broadcasting might take to fulfil a public service mandate and these include the strengthening of the public service broadcasting model along normative public sphere principles. The findings of the analysed election newscasts confirm that ZBC television election news was constructed in favour of ZANU PF at the expense of voices from other social and political constituencies. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Individuals are required to manage multiple tasks which require strategic allocation of time and effort to ensure goals are reached efficiently. By providing the worker with autonomy over their work, performance and worker well-being have improved. This increased control allows individuals to organize work according to the needs of the body, which prevents fatigue leading to improved productivity. When given the option, humans tend to switch between tasks frequently. This behaviour can be used to determine the change in self-regulation strategies. An understanding of human task-switching behaviour is important for the design of job rotation systems. However, there is a lack of evidence explaining the factors motivating the need to switch between tasks. This study aims to use physiological, subjective and behavioural measures to explain the factors influencing selfregulation through the act of task-switching. Three primary hypotheses were developed to explain the factors underlying taskswitching behaviour. It was hypothesized that the degree of boredom experienced, the effort required to perform the task and the resource usage induced by the task are factors responsible in deciding task switching behaviour. Participants (17 males and 17 females) switched freely between five different information-processing tasks for the 45 minutes. Participants were allowed to switch back and forth between tasks and did not have to conduct all five tasks. The following measures were recorded during the experiment: subjective measures of boredom, mental effort, task frustration and perceived performance of the tasks; energy consumption and physiological measures of effort (HR, HRV and body temperature) and behavioural measures, including duration and frequency of task. Perceived boredom was found to differ among the tasks and before and after the experiment. The average boredom rating at each task transition for all tasks exceeded a score of 2.5 out of a possible 4. There were no significant changes in physiological measures between the beginning and end of the task trials. However, changes in physiological measures showed a decrease in effort investment following task transition. Heart rate variability was lower for externally-paced tasks than for self-paced tasks, despite the differences in cognitive demands. The most frequent task-switch combination occurred between tasks of high and low cognitive demand. The least frequent task-switching combination occurred between tasks of similar characteristics, which produced no differences in physiological responses. Task-switching behaviour was influenced by the degree of boredom, and therefore more time was spent on less monotonous tasks. The level of physiological effort required for the task affected task-switching behaviour. Task switches were made before any changes in effort took place in an attempt to maintain task efficiency. It appears plausible that a task switch was made to reduce effort investment and activation levels. The type of information processing resources used by different tasks affected the task-switching combinations. Individuals tended to switch between tasks of differing resources so that those in limited supply were able to replenish. Therefore the findings from this study can potentially be used to improve the design of job rotation systems. Such improvements may enhance productivity and worker well-being by inhibiting the onset of down regulation and fatigue processes. This study showed that autonomy is necessary for individuals to regulate behaviour to suit human needs. , Microsoft� Office Word 2007 , Adobe Acrobat 9.54 Paper Capture Plug-in
