The Natural Sciences, Physical Sciences and Life Sciences curricula statements form the basis of this research. This study strove to establish how science teachers responded to the inclusion of indigenous knowledge systems (IKS) in their science classrooms. My study began with 23 science teachers who completed a university module ―Issues in Science Education,‖ which included an IKS component. The study investigated firstly, what currently informed teachers‘ thinking, knowledge and action of IKS. Secondly, the research questioned how teachers interpreted and implemented IKS in the science classroom. A sample of three teachers were followed into their classrooms to investigate how they specifically implemented Learning Outcome Three related to IK in the Science Curricula Statements, and what approaches pertinent to the inclusion of IK were developed. That is, the study explored how shifts were being made from a theoretical phase at the university where teachers engaged IK to an actual phase of implementation in their school science classrooms. Finally I attempt to explain why the teachers interpreted and implemented IK in the way they did. Production of data took place from 2006 to 2007, and used surveys, telephonic interviews, written assignments, face-to face interviews, classroom observations and reflective interviews. The three case studies involved three science teachers at three secondary schools in the province of Kwa-Zulu Natal, South Africa. The study found that the three teachers used three very different approaches through which IKS was brought in the science curriculum: an incorporationist approach, that brings IKS into science by seeking how ―best IKS fits into science‖; a separatist approach that holds IKS ―side-by-side‖ with scientific knowledge; and an integrationist approach that ―links‖ and makes ―connections‖ between IKS and science. The approaches developed by the teachers were found to be informed by their biographies, values, cultural backgrounds and worldviews. - vii - TABLE OF CONTENTS DEDICATION iii ACKNOWLEDGEMENTS iv DECLARATION v ABSTRACT vi TABLE OF CONTENTS vii LIST OF TABLES xii LIST OF FIGURES xii APPENDICES xiii GLOSSARY OF ACROYNOMS AND ABBREVIATIONS xiv CHAPTER 1 1 1.1 INTRODUCTION TO STUDY 1 1.2 STUDENTS OR LEARNERS PERFORMANCE IN SCIENCE 4 1.3 INAPPROPRIATE AND IRRELEVANT SCIENCE CURRICULUM 6 1.4 CULTURE AND SCIENCE 7 1.5 INTERNATIONAL INITIATIVES IN IKS 9 1.6 EMERGENCE OF IKS IN SA 10 1.7 IKS IN SOUTH AFRICAN EDUCATION 11 1.8 TEACHING SCIENCE AND IKS 14 1.9 RESEARCH QUESTIONS 19 1.10 THE PLAN OF THE DISSERTATION 20 CHAPTER 2 23 SCIENCE EDUCATION REFORMS AND IKS IN SOUTH AFRICA 23 2.1 INTRODUCTION 23 2.2 SCIENCE EDUCATION CURRICULUM REFORMS 24 2.2.1 Early Science Curriculum Reforms 25 2.2.2 Science Education for All 27 2.2.3 A Science, Technology and Society (STS) Approach 29 2.2.4 Science Education in Africa 31 2.2.5 Science Education in South Africa during the Apartheid Era (1948-1993) 32 2.2.6 Science Education in Post Apartheid South Africa (1993-2008) 35 2.2.7 Science National Curriculum Statement and IK 38 2.3 (DIS) CONNECTIONS BETWEEN WESTERN SCIENCE AND IK 47 - viii - 2.3.1 Redefinition of Science 47 2.3.2 Meanings of Indigenous Knowledge System 49 2.3.3 IK in South Africa 53 2.3.4 Meanings of Science 56 2.3.5 Nature of Science 58 2.3.6 Relationship between Science and IKS 58 2.3.7 Studies including IKS and Western Science 60 2.4 TEACHERS‘ SCIENCE KNOWLEDGE, PRACTICE AND IKS 63 2.4.1 Science Teachers‘ Subject-content knowledge 64 2.4.2 New Demands on South African Science Teachers 67 2.5 CONCLUSION 69 CHAPTER 3 71 SCIENCE EDUCATION AND IKS: 71 FROM CONSTRUCTIVISM TO POSTCOLONIALISM 71 3.1 INTRODUCTION 71 3.2 CONSTRUCTIVISM 72 3.2.1 Radical Constructivism 72 3.2.2 Social Constructivism 74 3.2.3 Critical Constructivism 76 3.3 BREAKING FROM CONSTRUCTIVISM: TOWARDS POSTCOLONIALISM 78 3.4 WORLDVIEW THEORY 80 3.4.1 Traditional and Western Worldviews 83 3.4.2 Language and Worldview 87 3.4.3 Border-Crossing 89 3.5 POSSIBLE MODELS FOR ‗IKS IN SCIENCE‘ TEACHING 91 3.5 CONCLUSION 94 CHAPTER 4 96 RESEARCH METHODOLOGY 96 4.1 INTRODUCTION 96 4.2 THEORY AND RESEARCH DESIGN 97 4.2.1 Interpretive Research as an Approach to the Study 97 4.2.2 Case Study 98 4.2.3 Triangulation 101 4.2.4 Narratives 102 4.2.5 Sample 103 - ix - 4.2.6 Methods of Data Production 108 4.3 PHASES OF DATA PRODUCTION 109 4.3.1 Imagined/Hypothetical Phase 110 4.3.1.1 Introducing the Research to the participants 111 4.3.1.2 Survey 112 4.3.1.3 Analysis of assignments 112 4.3.1.4 Telephone Interviews 113 4.3.1.5 Face-to-Face Semi-Structured Interviews 114 4.3.2 Implemented/Actual Phase 115 4.3.2.1 Classroom Observation 116 4.3.3 Reflective Phase 117 4.3.3.1 Reflective Interview 118 4.4.
