The Department of Education has introduced a policy of Continuous Assessment (CASS) in grades 11 and 12. This, however, does not mean that the current policies such as senior certificate examinations will immediately change. It appears that the old and the new practices will co-exist. This implementation of CASS took place in some environments characterised by enormous infra-structural backlogs, resource limitations, inadequate supply of quality learning support materials and absence of common national standards for learning and assessments. Consequently, the purpose of this interpretive research is to investigate how CASS has been implemented in grades 11 and 12 Physical Science classrooms in three disadvantaged secondary schools. This research study is a qualitative case study of three secondary schools in a school circuit. The three secondary schools were chosen on the basis of their varying socio-economic backgrounds and history related to quality of work and innovation. The research study examines the contexts and processes that took place during the implementation of CASS in these schools. The principal theories underpinning this study are those supporting educational change and curriculum innovation. The argument is that different understandings of the nature of the curriculum have important implications for the implementation of curriculum change. The literature was reviewed to expand the argument that curriculum change has different meanings and is dependent on the context. In this research study, curriculum changes in South Africa, the meaning of curriculum changes, CASS and CASS policy are discussed. The research methods used to gather data are semi-structured interviews, document analysis and questionnaires. The participants in this study were grade 11 and 12 Physical Science teachers, the Science Head of Departments (HOD) and grade 11 and 12 Physical Science learners from each school. The three schools were visited in the second half of 2002. This research study considered the roles and importance of learners, teachers, school management team, community and external inputs for the successful implementation of CASS. The feedback from teachers, HOD's, and learners were analysed and discussed. The schools were found to have profiles and strategies that were unique, but also some principles, practices and characteristics were common. The overall findings show that CASS has been implemented in these classrooms, but the strategies that are mostly used are those which were used in a content-based curriculum. For example, tests, classwork and homework were common in these schools. This study therefore suggests that more thorough and different support and developmental programmes be put in place so as to equip teachers with the skills necessary to implement CASS. This study also suggests that further research in schools be conducted, so that the best procedures are used to ensure the effective implementation of curriculum innovation in South Africa. / Theses (M.Ed.)-University of KwaZulu-Natal, Durban, 2004.

Alice, a secondary teacher from Quebec, Canada is the focal point of this qualitative case-study research. She is a Caucasian, 37 year-old, married woman with three children. Alice is selected for the following reasons: primarily, she is a science teacher, who has received a provincial award Prix de merite de la conservation de la faune for a project, that is a demonstration of creativity in her field. Secondarily, I share many attributes with her including being married with children, and being a science teacher. Data were gathered from July, 1998 to July, 2001. Data sources included five one-to-one interviews with Alice. Additional data sources included one interview with June (mentor-colleague) and Jane (Departmental Head); two classroom observations; 1996 retrieved interview; and artifacts of students' work. All interviews were audio-taped verbatim and then transcribed, and observations videotaped. The overarching themes represented constructs involving community, values, and interpersonal skills. Alice's values, her bent towards community, and her way of life in constructing interpersonal relationships contribute to her creative teaching. Alice's philosophy of grounding education in the community determines who she is, and encompasses her creative process which begins with recycling of community resources and giving back to the community through the creative products developed by her students. Her values guide her practice and teaching decisions. This case study of creative teaching highlights the domain of teaching as different from those addressed by studies on creative giants and presents an inspirational model for individuals in the teaching profession.

The primary objective of this study was to implement a project that utilizes telecommunications as a tool to enhance the grade eight science curriculum. The process of becoming prepared to undertake this study was examined and documentd so that teachers in all subject areas at all grade levels could use it as a guide for similar projects. It was proposed to do this by conducting a collaborative project in which the students would use the scientific method to develop research questions that could be used to discover why the incidence of asthma is so high in Central Alberta. These questions would be sent out to schools across Canada and then the data would be analyzed and interpreted. The results would be shared with all participants as well as asthma researchers. The study met with many barriers whcih impeded the progress as well as made it impossible to fulfil the original goal of having the students collaborate with the experts and contribute their own research to the field. Whe embarking on a new project using technology it is inevitable that there will be barriers. Through repeated reconnaissance we were able to adjust our goals and still pursue very worthwile, but very different computer and telecommunications projects. The students attitudes towards learning science, science in society and computers were measured by pre and post surveys. The findings showed that the students were aware of the importance of all these factors in their lives. Without completing the asthma study, it is impossible to know how much of a difference there would have been in the results. The qualitative results showed very clearly that computers are a motivator for students. They enjoy working on them and the challenge they present. Many of them will do extra homework so that they can take advantage of every opportunity to work on the computer. Unfortunately, many teachers do not have the time or support to learn enough about the Internet/Schoolnet and what is available to take full advantage of what is has to offer our students and ourselves. For the most part, there are few teachers in each disrict becoming involved. This will change over time only if there is a support system in place and the pioneers share what they have learned. We cannot run the risk of the forerunners becoming discouraged and giving up. The Internet is a global community. For that community to grow and flourish we must share what we have learned and provide the means to make the path smoother for those who follow. Through this study, the projects have been documented and resources have been prepared that are intended to help others get online and access a wide variety of resources that are sure to enhance all programs and professional development. / xiii, 228 leaves : ill. ; 28 cm.

Knowledge production or research in South Africa, as elsewhere in the world, does not occur within 'innocent' spaces devoid of personal, social, political, economic and cultural contexts (Singh, 2000). This study explores knowledge production at the level of policy. It questions in the review of the school's curriculum policy in general, and the science curriculum policy in particular: What becomes new? What is different? What remains the same? What is the policy problem? Who is the policy population that is the target of such policies? Why is there such a universal dimension of what should be taught in science, and hence what science is? Why is the conceptual knowledge of the science curriculum and the conception of scientific literacy around the world much the same? At the level of research, what is the most illuminative way to seek answers to these questions? The study explores the theoretical, methodological and contextual constructs that frame the conception of scientific literacy. This thesis presents a critical analysis of the policy process and policy documents for two reform periods in South Africa. The theoretical constructs deployed are policy archaeology, ideology, inclusivity, governmentality and professionalisation. I argue in this study that the latter two constructs are regularities that are necessary for the emergence of the policy problem, they shape the social construction of the policy problem and they constitute and shape the range of policy solutions. I posit that these regularities are necessary for the social construction of the policy problem in both the C2005 and the RNCS processes. These regularities intersect in a complex, grid-like fashion on the policy-problem axis. These intersecting regularities makes it possible for the policy problem to emerge as a problem, constructs the problem, and constitutes the problem as an 'object' of social visibility. I argue that ideological shifts in the conception of scientific literacy are constituted by these two regularities. I conclude the thesis by drawing out five significant policy lessons: (i) An 'ideal' that makes intellectual sense but does not fit conditions in society can exacerbate the problems it seeks to solve; (ii) 'Change is only as effective as the smallest unit': in the policy-making arena the smallest unit is the policy writers, in the arena of practice it is the classroom teacher; (iii) Timing determines what is possible: the socio-political climate of 1994 resulted in some important silences- especially from conservatives and scientists; (iv) In the science policy documents the definition of scientific literacy is epistemological at two levels: the idea that scientific literacy can be defined and constitutes individual knowledge,and the view of knowledge in the policy documents; and (v) The policy process and the policy documents challenged hegemony of structure and the epistemology of knowledge. / Thesis (Ph.D.)-University of KwaZulu-Natal, Westville, 2005.

This study describes, discusses and analyses the Rwandan lower secondary school teachers’ responses to the introduction of inquiry as a teaching approach in the science curriculum as one of the changes that the curriculum in Rwanda has undergone through in the aftermath of the 1994 genocide. The study investigates the science teachers’ understanding of inquiry-based science teaching, their attitudes towards the introduction of inquiry into the science curriculum, the activities they are engaged in with regard to inquiry-based science teaching and learning, the factors influencing their current teaching practices and their perceptions about what may be done for a better implementation of inquiry-based science teaching. Guided by a pragmatic research approach, I believed that collecting diverse types of data would provide a deeper understanding of the research problem and therefore adopted a two phases’ sequential explanatory mixed methods design. During the first phase, data were collected by means of a survey questionnaire administered to a purposeful sample of 200 science teachers at lower secondary school in Rwanda. Findings from the survey informed the second phase consisting of data collection by means of semi-structured one-to-one interviews with 15 purposefully selected teachers from the sample used in the first phase then supplemented by a contextual observation in their schools. The data from the questionnaire were subject to a descriptive statistical analysis while data from interviews were subject to analysis involving transcribing and reading interview transcripts, coding and categorizing information, identifying patterns, and interpreting. The data analysis produced five main assertions providing answers to the research questions. Participant teachers displayed varying understanding of what inquiry-based science teaching is, associating it with a number of its characteristics such as a learner centred teaching approach mostly based on experiments and practical work. There were a few teachers who did not have accepted understandings of inquiry-teaching. Furthermore, teachers had a positive attitude towards the introduction of inquiry and favoured the change even though they indicated a number of factors preventing them from adequately implementing the new teaching approach. As for their practices, traditional classroom activities were more frequently used than inquiry-based activities and when they made use of inquiry, they followed a specific order of activities that led to a more structured type of inquiry. The study further identified a number of factors influencing both positively and negatively the implementation of inquiry. The positive aspect was that they find teaching through inquiry more enjoyable while the shortage of time, the lack of teaching resources and the lack of confidence associated with inadequate training, influenced negatively the way they implemented inquiry-based teaching. Teachers highlighted a number of interventions they felt would make the implementation of inquiry based teaching more effective. The improvement of resources provision to schools and the implementation of adequate professional development programmes were the most highlighted. Despite the several impediments to the implementation of effective use of inquiry, teachers were optimistic towards the future of science teaching and learning in Rwanda. It is envisaged these findings will be valuable to a wide range of audiences including science teachers, curriculum developers, science teacher educators as they may inform them about the implementation of the new curricula that require teachers to focus on inquiry given the controversy surrounding this issue in science education. / Thesis (Ph.D.)-University of KwaZulu-Natal, Durban, 2012.

The purpose of this study is to investigate the impact of computer technology on teaching Natural Science (NS) in grade 8 classes. Computer technology is the powerful and influential tool in teaching and learning situation. When it is used appropriately it will support the NS educators in their teaching of NS. Indeed computer technology could be used to redress the inequalities of the past, especially in the teaching of Natural Science as they offer the educators whether in rural or urban area a common base of knowledge and experience. The term computer technology is used interchangeable with the term Information and Communication Technology. The term computer technology has the different meanings from the different authors but in these meanings that they gave, there are similarities that computer technology is a tool used for developing, implementing and evaluating the teachings aids. There are different ideas about the impact of computer technology on teaching NS because other authors in their studies state that it has a positive impact yet others state the negative impact of computer technology. Those they state the positive impact look at a dimension of the developing the teaching skills, creative thinking and problem solving skills in education. The other authors state the negative impact of computer technology look on the dimension that it is too early to conclude that computer technology has a good impact because some of the educators in the teaching field are not well trained to teach using computers. They also state that computer technology will have negative impact on teaching because in the schools where these educators worked there is no follow up after they attended the workshops to look that are they do what they are trained to do. The findings show that computer technology has a positive impact because 75% educators have a full understanding of computer technology and they apply in their teaching and learning of NS. This means that these results are supporting ideas of these authors that they were stating that computer technology has positive impact. There were few educators that they have no understanding of teaching using computers so they have a negative attitude of computer uses in teaching. These educators are supporting the views of the authors that in their studies they shown the negative side of computer technology in teaching. This study concludes that the Dinaledi project and the department of education must make it sure that they do the follow up that computers are used purposeful to schools that they have them. The trainings workshops must be long so these educators will acquire these teaching skills thoroughly. / Thesis (M.Ed.)-University of Kwazulu-Natal, 2006.

The purpose of this study was to describe the performance of the South African Grade 8 learners in Trends in International Mathematics and Science Study (TIMSS) 2003 science test, to explore the translatability of TIMSS 2003 science items into isiZulu without significant loss of meaning, and to explore the strategies used by isiZulu-speaking learners when answering questions in the TIMSS 2003 test. Thirty six isiZulu-speaking learners were tested using written test questions taken from the science test in the TIMSS 2003. The degree to which a sample of 36 learners represented their understanding of the questions in a written test compared to the level of understanding that could be elicited by an interview is presented in this study. The findings of this study are presented, interpreted and discussed using Pollitt & Ahmed's (2001) model of question answering process as well as other relevant literature. The key findings of this study are as follows : • the South African Grade 8 learners performed very poorly on TIMSS 2003 science test, • close translation of TIMSS 2003 science items into isiZulu is possible if conducted with care by expert teachers, • the language of the test had some effect on isiZulu-speaking learners' performance on TIMSS 2003 science test, • the strategies used by isiZulu-speaking learners when answering science questions included: • translating the question into isiZulu before trying to answer it, • choosing an answer containing a word/term common in the question stem and in the options, • choosing the answer containing a familiar/unfamiliar word in the options, •guessing , •looking at patterns of previous choices, •'picture memory', and •'general knowledge'. When Pollitt & Ahmed's (2001) model of question answering is applied to isiZuluspeaking learners, two 'new' phases are introduced. The findings of this study suggest that language factors are embedded within other factors, importantly, the appropriate level of cognitive proficiency to enable correct answering of science questions. The findings of this study further suggest the need for development of cognitive/academic language proficiency (CALP) in both English and isiZulu languages, or in one of them. / Thesis (M.Ed.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.

It has been discovered that in many countries, both locally and internationally, girls have low participation rates in science at secondary school level. This thesis examines the factors that underscore the persistence of girls' low participation rates in schools. The major reason for this examination is to establish ways in which secondary school teachers, interested individuals or groups of people, and the ministry of education in Lesotho can manage this problem. Kelly (1981) argues that causes of girls' negative attitudes towards science are multifaceted. Thus, in attempting to understand these causes and to develop strategies to manage this behaviour, a single approach, which focuses on student-teacher classroom interaction, was considered. This thesis therefore, seeks to investigate the responses of girls and science teachers in schools with least numbers of girls having opted for science in the last five years. Due to less numbers of science teachers in schools, I involved in this study, all those found in schools surveyed. To survey girls' responses to this problem, I drew a random sample of both those who have opted for, and those who have opted out of science. I then used a self-administered questionnaire as the research instrument for this study. Basing myself on my judgement's analysis, I therefore concluded that gender discrimination is the major source of girls' negative attitudes towards science in Lesotho, the country that condones female subordination. The unfavourable learning atmosphere that male teachers create for girls in science lessons, such as, the harassment, the harshness, deprivation of opportunity to participate in class, to use the laboratory equipment and other ways and means of ill-treating and frustrating girls are all a result of male domination. A number of recommendations to manage this problem have therefore been proposed. / Thesis (M.Ed.)-University of Natal, Durban, 2002.

This creative project consisted of the development of a workbook entitled, Building a Chemical Background for the Study of Biological Sciences. The workbook has been created for use in advanced high school level science classes or as a reference in undergraduate college biology courses. The workbook covers the following subject: atomic structures, covalent bonding, acids and bases, energy, water, hydrocarbons, functional groups, carbohydrates, lipids, proteins and nucleic acids.Field-testing was done on the workbook by one advanced high school chemistry class and two college freshman level biology classes. The percent gain for the high school field-testing was 68.9%, while the percent gain for the college experimental group was 22.7% and the percent gain for the college control group was 20.9%.
