A thesis submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfillment of the requirements for the degree of Doctor of Philosophy Johannesburg, South Africa June, 2015 / This doctoral thesis investigates highly emotive and topical aspects of student learning in higher education namely, assessment and feedback. The study deals with the complexities and barriers to using learning-oriented assessment approaches to equip students with skills needed to thrive within the uncertainty, demands and challenges of rapidly changing societies. In the current research literature, views about assessment, and in particular formative assessment, are diverse and in some instances contradictory. The argument I make in this thesis is that assessment is situated within a local context, comprised of students and their teachers, which is regulated by disciplinary, professional and institutional traditions, expectations and needs. This research study was impelled by the realisation that most research into pedagogical views held by teachers and their students in higher education has examined them in isolation of each other. In recognition of this disparity in the literature, a more comprehensive study on teachers' and students’ views, expectations, and experiences of assessment was undertaken in the South African context. The study was conducted at a research-intensive university and investigated the aforementioned assessment aspects in students and teachers involved in second year compulsory bioscience courses. Using an exploratory, interpretative, mixed method research approach, data were collected through a combination of interviews, questionnaires and document analysis. An in-depth examination of documents from the selected courses, including students’ marked work, provided evidence of assessment and feedback practices experienced by the students registered in the courses. Teachers were interviewed about their assessment practices and their rationale for using these practices. Students' views and their reactions to assessment and feedback were ascertained through questionnaires and interviews. Interpretations that emerged from using a socio-cultural-historical theoretical lens were helpful in understanding the factors that present challenges to the implementation of learning-oriented assessment approaches. From the characterisation of assessment environments based on learning-oriented assessment principles it was apparent that there was limited active involvement of students in the process. The data highlighted a complex array of factors influencing teachers’ conceptions of assessment and subsequently their practices. Significant about the study was the identification of the effects of existing course level assessment cultures and histories on teachers’ assessment practices. Program and course factors had more influence on teachers’ practice than their subject expertise, pedagogical beliefs and values. The main highlights emerging from the study were the multiplicity of students’ and teachers’ views of assessment and feedback with a number of convergent and divergent perspectives. Notably, the cause of dissonance between academics and students stems from the tension between the competing needs of facilitating students’ independence and the desire to give them detailed corrective feedback. This dissonance translated into varied emotional responses to feedback from students. Although the focus of the study was on the comparison between students’ and teachers’ understanding of assessment, the preponderance of students’ emotional reactions to assessment feedback that emerged offered an important insight into an unpredicted social-relational dimension of assessment. My original contribution to research knowledge is the generation of the Assessment-Systems-for-Practice (ASP) framework, a reflection and methodological tool for investigating and analysing assessment practices. This framework provides a holistic way of dealing with the complex nature of assessment in higher education. The framework thus has implications for assessment design that would take into consideration cognitive, structural and social-relational dimensions, and its use could have a positive impact on teachers’ individual assessment practices.

M. Tech. Business Information Systems / Information technology (IT) rapidity, and the pervasive implementation of new technologies in the education system, has tremendously improved the way teaching and learning is conducted. Institutions are being reshaped by the rapid provision of education services anytime, anywhere regardless of the constraint of space and geographical boundaries. This has enhanced collaboration among educators as well as their learners by sharing and disseminating of knowledge. However, this sharing of knowledge is still limited as educators have not fully exploited IT to share knowledge. The major objective of this study was to develop a framework for utilizing IT to enhance knowledge sharing for mathematics and science teachers.

This research study involves two Grade 9 Natural Sciences teachers from two schools in the Lady Frere District of the Eastern Cape. The reason for selecting these two teachers is that in 2009 they, like me, obtained an Advanced Certificate in Education (Science and Maths) from Rhodes University. As a result, we have a good working relationship. Furthermore, both teachers are actively involved in the Natural Sciences curriculum in the District and their schools are not far from the District Office where I work. The principal objective of this study was to investigate how Natural Sciences teachers mediated learning in order to enhance conceptual development and understanding of chemical reactions in Grade 9. It was triggered by the transformation in curriculum in South Africa as well as by my experience of working with Natural Sciences teachers in our rural district. The study is informed by an interpretive paradigm using a qualitative case study approach. The data was gathered by administering analysis of documents, semi-structured interviews, observations, field notes and journals. During the data analysis process, patterns and themes were illuminated using the inductive analysis method. Rich data sets in relation to the main research question on how Natural Sciences teachers mediated learning in order to enhance conceptual development and understanding of chemical reactions in Grade 9 emerged from the analysed data. The conclusions that can be drawn from the study indicate that when teaching chemical reactions, teachers should have adequate content knowledge as well as pedagogical content knowledge. It is thus recommended that teachers consider the prior knowledge of learners, use a variety of teaching and learning approaches including practical activities, to make learning meaningful. The major limitation of this study is that the two selected teachers do not represent the whole population of Grade 9 teachers in the Lady Frere District. Therefore, the findings cannot be generalized to represent the larger population. It is recognised, however, that within the qualitative inquiry, reliability and generalizability play a minor role.

Bibliography: pages 73-82. / Using 262 acknowledged science educators from 41 countries, Bybee developed a scale for measuring the ranked priorities of scientists, and others, with respect to twelve major global problems related to science and technology in 1984. In 1993 this scale was re-administered to samples of 76 Cape Town science educators, 55 Transkei science educators and 129 chemical engineering undergraduates at the University of Cape Town. High correlations ranging from r = 0.68 to r = 0.90 were obtained among the four samples' mean ranked priorities on the scale as a whole, over the ten year period. Among the top six global problems in 1984, five still received consistently high overall prioritisation in 1993, namely: population growth; world hunger and food resources; human health and disease; air quality and atmosphere; and water resources. The mean ranking of war technology as a priority declined by seven places over the ten year period. Educators surveyed in follow-up studies in 1993 made numerous recommendations for teaching these global problems. These included the use of the science-technology-society (STS) approach in science education; the introduction of a core school curriculum on environmental education; the encouragement of student participation in projects which help to reduce or eliminate such global problems; and the re-allocation of money spent on nuclear arms towards the satisfaction of human basic needs such as food, housing, health and water services. In a follow-up survey of twenty lecturers in engineering at the University of Cape Town in 1993 and 1994 important goals and issues singled out by individuals included the provision of mass housing and infrastructure; sanitation; urbanisation; job creation; the abuse of high technology in communications; technological illiteracy among decision makers; abuse and reduction of oceanic resources; photochemical smog; the prediction and possible control of droughts and floods; demands on the human race of the information explosion; electromagnetic wave hazards and pollution; resource depletion education and the dissemination of knowledge; the emergence and separation of C.P. Snow's "Two cultures"; and the myth of the peace dividend. Several of these issues were then subsequently included in 1995 in an updated, modified and extended form of the Bybee Scale. Currently a reliable and validated 15-item Scale -emerging from the findings of this dissertation - is being employed by other research workers in various parts of the new South Africa. During 1995 its chief use has been offering relevant input into, and providing empirical justification for, fundamental aspects of the policy of the current Reconstruction and Development Programme, as set out in the 1995 White Paper of the Government of National Unity.

Mathematics and science form an integral part people’s daily lives. South African people suddenly find themselves on a technological highway, where mathematical, scientific and creative thinking as well as problem solving skills take centre stage. However many people fear these, and believe that they are unable to tackle them. Mathematics and science educators therefore have need to have knowledge and understanding regarding 6 the foundation of the teaching of these subjects in the intermediate and senior phases at schools. This should enable them to contribute positively towards changing people’s perceptions about these subjects. Based on the above information I felt it imperative for me to investigate the impact of shortages of maths and science educators with special reference to the Buffalo City Area. Purpose of the study: 1 To determine whether schools are able to attract and retain qualified maths and science educators, 2 To identify the quantity of quality maths and science learners schools are able to produce for tertiary education, 3 To investigate the rate of turnover of maths and science educators, 4 To identify the number of maths and science learners who are willing to study maths and science at tertiary level and thereafter join the teaching fraternity.

Abstracts in English, Xhosa and Zulu / The rationale behind this study was, to explore how unqualified natural science teachers in grade seven conduct practical work. Furthermore, the study explored an understanding of some of the experiences, beliefs and views of unqualified NS teachers. This was a qualitative study. Data was collected through classroom observations and semi-structured interviews. The three cases were interviewed and observed separately. This study was guided by main research question: How do unqualified grade seven natural science teachers facilitate practical work in the senior phase? Which was further unpacked into three sub-questions: How do unqualified NS teachers define practical work? What are the views, aims and objectives of unqualified NS teachers about practical work? How do unqualified NS teacher conduct practical work? The study revealed that in all three cases, practical work was conducted consecutively as poorly, outstandingly, and excellently. Moreover, an intensive professional pedagogical development is recommended for natural science teachers. / Isizathu emva kwesi sifundo sasiyihlolisise indlela abafundisi bezesayensi bezendalo abangafanelekanga ngayo kwiibakala ezisixhenxe ezenza umsebenzi osebenzayo.

Continuing Professional Development (CPD) of teachers is increasingly becoming a priority in most countries throughout the world. It is widely viewed as the most effective approach to prepare teachers adequately, and to improve their instructional and intervention practices, for when they enter the workforce (Fraser et al 2007). Despite the general acceptance of CPD programmes as essential to the improvement of education, reviews of professional development research constantly point out the ineffectiveness of most of these programmes (see Cohen and Hill, 1998 and 2000). Furthermore, many teachers express dissatisfaction with the professional development opportunities made available to them in schools and insist that the most effective development programmes they have experienced have been self-initiated (National Research Council, 2007). There is a consensus that many CPD programmes have yet to understand professional development from a teacher‘s perspective. This perspective acknowledges what drives teachers to enlist in these programmes and how such programmes can make a difference to them and their classrooms. Therefore, this study seeks to return the emphasis of professional development to the teachers. The study explores the teachers‘ perspectives of CPD in general, the personal meaning of CPD, and its meaning in the context of their work. By interviewing the teachers who were part of the Mpumalanga Secondary Science Initiative (MSSI) project (a seven year science and mathematics professional development intervention), I explore: the teachers‘ opinions of the intervention; its meaning to them and their work; and its impact on their classroom practices and students for the duration of the intervention and beyond. In this study, I explore data from an extensive and longitudinal study of teachers who were part of the CPD programme in greater detail. In discussing my data, I propose that CPD, however well intentioned and executed, is received differently by each teacher as a result of their personal circumstances and investment in the programme. I argue that the greater the unity between the personal circumstances and motivations of the teachers and those of the CPD intervention, the more likely the outcome will be meaningful for the participating teachers. In turn, the ability to sustain the benefits of the intervention will be enhanced. / Further Teacher Education / D.Ed. (Curriculum Studies)
