COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR
Que tipo de professor de ciências da Educação Básica pode levar um aluno a querer ser um cientista? Como aprendeu Ciências na Educação Básica quem hoje produz Ciência? Para responder a estas questões, investigou-se em que medida e de que modo a prática de professores de Ciências da Educação Básica influenciou cientistas em sua opção profissional. Foram aplicados questionários e gravados relatos de cientistas da área de Ciências Naturais em atividade, a fim de identificar quais fatores consideram decisivos e marcantes em sua trajetória escolar como alunos de Ciências. Destes fatores, mereceram destaque aqueles relacionados ao papel dos seus professores de então, em sua opção profissional pela pesquisa científica. Através da evocação das lembranças desses cientistas, procurou-se detectar o papel representado por seus antigos professores de Ciências. Que características são atribuídas aos bons professores desta área? O que pensam os cientistas sobre formação de professores de ciências? Estes relatos trouxeram pistas que apontam como alguns dos entrevistados decidiram-se tornar cientistas na área de Ciências Naturais por causa de ou apesar de seus professores de Ciências, bem como a influência de outros fatores em sua opção de carreira. Espera-se assim, que este trabalho possa trazer novos subsídios ao campo de formação e prática de professores de Ciências.
What kind of science teacher of Basic Education would make a student wonders to be a scientist? How have learned science on Basic Education a person that now produces Science. To answer those questions, it was investigated how much and in which way the practice of science teachers of Basic Education had influenced scientists on their professional option. Questionnaires were applied and interviews with scientists currently working on Natural Sciences were taped with the purpose to identify which factors they considered decisive and remarkable on their school trajectory as science students. Any kind of influence of the teachers on the professional option of the scientists was highlighted. The evocation of the memories of these scientists was done trying to detect the importance of their science teachers. Which are the characteristics that make them good teachers on the field? What scientists think about the formation of science teachers? These reports gave clues hinting how some of the interviewees had decided to be scientists on the Natural Sciences field because of or in spite of their science teachers, as well as the influence of other factors in their career option. One expects thus, that this work can bring new subsidies to the field of formation and practices of Science teachers.

Abstract:
This textbook is intended for first-year college students in biology, chemistry, or physics. Its most distinctive feature is the central role played by applications to the natural sciences. Considering that nowadays students have access to graphing calculators that can solve complicated integrals, little or no space has been devoted in the book to integrals that require subtle changes of variables. Rather, we choose to concentrate on the basic techniques of integration and stress the solution of applied problems, especially those that use real data. We envision a calculus course where students not only learn to calculate derivatives or solve integrals, but are also able to discuss the validity of a model and estimate parameters.

Abstract:
The philosopher Georges Canguilhem observed that the “physician’s thought and activity are incomprehensible without the concepts of the normal and the pathological.” I argue similarly regarding the biologist, only it is “the artificial” and “the natural” that are indispensable. Whether it is their objects of study, the methods used to investigate those objects, or even fellow researchers, biologists have habitually classified aspects of their discipline in a way that reflects the artificial-natural distinction. Why this way of classifying? What purpose does it serve? What principles guide its application? With what repercussions? Tracing the transformation of these concepts through a series of historical episodes, I explore the reasons why biologists use this distinction and how it has influenced the practices and directions of certain biological fields—specifically evolutionary biology and ecology. The argument of this dissertation is that in biology decisions concerning the choice and evaluation of experimental and evidential practices, objects of study, and even assessments of scientific personas betray the artificial-natural distinction. Invocations of this distinction, like the normal-pathological, code normative contentions about proper biological practice. “The natural,” I argue, often functions as an epistemic authority. The methodology I employ in this dissertation is conceptual and historical. The arguments marshalled are supported by conceptual-philosophical analysis, close readings of primary texts, and archival work. In the end I aim to problematize a set of widely invoked, but heterogeneously used, biological concepts. My arguments undermine a commonplace view according to which the collapse of the artificial-natural distinction is a prerequisite for contemporary science. This distinction is not, I argue, an outdated, pernicious relic; it has continued to exert a significant influence on scientific practice, and should not be ignored.

Abstract:
Nosso estudo busca apresentar as etapas da formação do método morfológico de Goethe: do nascimento de sua empreitada em relação às ciências naturais, ainda ligado ao signo de Espinosa, até a tentativa de formação de um método que se pretendesse objetivo. Dada a sua intenção de estudar as formas e as formações do mundo orgânico o poeta se viu confrontado com as etapas de desenvolvimento do olhar, para depois lançar-se numa investigação acerca do espírito, devido à distância existente entre nós e os fenômenos. Da viagem à Itália, onde Goethe aprendeu a respeitar as formas da natureza de uma maneira despojada da ligação afetiva da subjetividade, até seus últimos anos, Goethe nunca abandonou a intenção de abordar os seres vivos, mas o processo de formação do método morfológico se formulou como um organismo que gera sempre novas formas de se buscar conhecer a natureza como algo que, como ele mesmo descreveu, ela é vida e desenvolvimento desde um centro desconhecido até uma desconhecível periferia. Neste caminho intentou uma abordagem simbólica da natureza e de suas formas: como a natureza não é algo que possamos evocar como um mundo secreto que se apresente imediatamente nas nossas representações, temos de encontrar o caminho de abordagem dos entes particulares ligados ao universal e como ponto de contração do caminho morfológico.Este não é um método acabado; trata-se, antes, de um método que se encontra em perpétuo fazer.
This study aims to present the steps of Goethes Morphological method, from its birth in relation to the natural sciences, still linked with the sign of Spinoza, to the trial of forming an objective method. As his intention was to study the forms and the formation in the organic world, the poet has found himself in confrontation with the stages of the development from seeing, and afterwards in an investigation of the spirit in terms of the distance that exists between us and the phenomenon. From the Italian journey, when Goethe learned to respect the forms in its nature without linking them with the subjectivity, to his last years of life, Goethe never gave up the intention of an approach to the natural beings. But this process was formulated as an organism, searching new forms to try to know the nature as something as he described, that acts it is life and development from an unknown center to an unknowledgeable boundary. In this way he tried to figure out an attempt to a symbolic knowledge of the world of nature and its forms, as nature is not a thing that we can evoke as an open secret, or as a thing that presents itself directly in our forms of representing. We need to find a way that attempts to these particularities and this is the concentrating point of the goethean´s morphological way. As can be seen, it is not a made method, instead, it is a method in perpetual making.

Abstract:
This study addresses the pro~ess of choice which young people go through at the age of 16, when making their educational choices beyond compulsory education. The issue of the supply of scientists into the workplace and higher education continues to be of concern to governments and educationalists alike. In recent years, some universities in England have been forced to close their physical science departments. Inthe academic year of 200212003 I listened to student voices through 49 individual student interviews supported by focus group and staff interviews. These were the young people who had recently undergone this choice process. Through these interviews I explored how the students' pedagogical experiences had impinged on their learner identities and consequently on their post-16 choices. Choice, for these young people, was taking place within the context of educational change. The 14-19 curriculum was under review with several interventions being put in place. One of the major interventions, to affect the students, was the introduction of Curriculum 2000 into further education colleges. The final outcome of the 14-19 review was published in a Government White Paper in 2005. There were also changes being considered to the Key Stage 4 Science National Curriculum. Choice at the age of 16 is the first major choice that young people have. In the literature review I have explored the concept of choice within the English educational system for parents as well as the pupils or students. This provides the context of choice within which the analysis can take place. The students' narratives contained two distinct strands. Firstly they looked back to their previous experiences and secondly they looked forward to notions of their future pathways. When looking back their choices were very much bound up with their learner identities, which had been constructed through their pedagogical expenences m secondary education. As a framework for the analysis of this theme of the students' narratives I have utilised the work of educational theorists in the area of pedagogy and identity construction, theorists such as Basil Bern~tein, PauJ Dowling and Etienne Wenger, amongst others. I have explored how the pedagogies of different subjects, in particular the natural sciences, have impinged on their identity construction. Within the pedagogical experiences of the students there emerged a dominant discourse creating a hierarchy of difficulty amongst different subjects, placing the natural sciences and mathematics as the most difficult. This differentiation between subjects is also to be seen within the official documentation surrounding science education. The aspect of the difficulty of the natural sciences became an important feature of the students' narratives impinging on both identity construction and post-16 choice. When looking forward to their educational or occupational careers the students were taking account of the recent changes in post-16 education, the demands of university entrance requirements and the need to remain flexible for today's workforce. I have explored how these changes have affected the choice of the natural sciences. A typical biographical pathway for the young people of today has become extended in length as they tend to take longer before making final decisions on their career options. When reflecting on the stories the students told, I assess how the recent changes to the science curriculum might address the issues raised. I also reflect on the study as a whole and look to possible ways forward.

Full text
Abstract:
Within the realm of the natural sciences there are different written genres for interested readers to explore. Popular science articles aim to explain advanced scientific research to a non-expert audience while research articles target the science experts themselves. This study explores these genres in some detail in order to identify linguistic differences between them. Using two corpora consisting of over 200 000 words each, a corpus linguistic analysis was used to perform both quantitative and qualitative examinations of the two genres. The methods of analysis included word frequency, keyword, concordance, cluster and collocation analyses. Also, part-of-speech tagging was used as a complement to distinguish word class use between the two genres. The results show that popular science articles feature personal pronouns to a much greater extent compared to research articles, which contain more noun repetition and specific terminology overall. In addition, the keywords proved to be significant for the respective genres, both in and out of their original context as well as in word clusters, forming word constructions typical of each genre. Overall, the study showed that while both genres are very much related through their roots in natural science research they accomplish the task of disseminating scientific information using different linguistic approaches.

Abstract:

This is a descriptive, exploratory, qualitative, collective case study that explores the pedagogical practices of science teachers who do not hold natural science degrees. The intent of this study is to support the creation of alternative pathways for recruiting and retaining high-quality secondary science teachers in K-12 education. The conceptual framework is based on Social Cognitive Theory & Self-Efficacy (Bandura, 1977; Bandura, 1997) and Problem-Solving & Transfer (Berg & Strough, 2011; van Merrienboer, 2013). The research questions are: What does science instruction look like in classrooms where science teachers without natural science degrees are teaching? and How do these natural science teachers without natural science degrees believe their prior experiences inform their instruction? The participants were 4 science teachers from middle and high schools in Southern California. The instruments used in this study were interviews, observations, and document analysis. The research revealed that science teachers without natural science degrees utilize techniques that make them high-quality teachers. The current qualifications for science teachers should be revisited to consider utilizing self-efficacious teachers with an interest in science and a passion for teaching students. Science teaching competency can be measured by more than natural science degree attainment.

Abstract:
Recent reform efforts in science education focus on scientific literacy for all citizens. In order to be scientifically literate, an individual must have informed understandings of nature of science (NOS), scientific inquiry, and science content matter. This study specifically focused on Science Olympiad students’ understanding of NOS as one piece of scientific literacy. Research consistently shows that science students do not have informed understandings of NOS (Abd-El-Khalick, 2002; Bell, Blair, Crawford, and Lederman, 2002; Kilcrease and Lucy, 2002; Schwartz, Lederman, and Thompson, 2001). However, McGhee-Brown, Martin, Monsaas and Stombler (2003) found that Science Olympiad students had in-depth understandings of science concepts, principles, processes, and techniques. Science Olympiad teams compete nationally and are found in rural, urban, and suburban schools. In an effort to learn from students who are generally considered high achieving students and who enjoy science, as opposed to the typical science student, the purpose of this study was to investigate Science Olympiad students’ understandings of NOS and the experiences that formed their understandings. An interpretive, qualitative, case study method was used to address the research questions. The participants were purposefully and conveniently selected from the Science Olympiad team at a suburban high school. Data collection consisted of the Views of Nature of Science – High School Questionnaire (VNOS-HS) (Schwartz, Lederman, & Thompson, 2001), semi-structured individual interviews, and a focus group. The main findings of this study were similar to much of the previous research in that the participants had informed understandings of the tentative nature of science and the role of inferences in science, but they did not have informed understandings of the role of human imagination and creativity, the empirical nature of science, or theories and laws. High level science classes and participation in Science Olympiad did not translate into informed understandings of NOS. There were implications that labs with a set procedure and given data tables did not contribute to informed NOS understandings, while explicit instruction may have contributed to more informed understandings. Exploring these high achieving, Science Olympiad students’ understandings of NOS was a crucial step to understanding what experiences formed these students’ understandings so that teachers may better their practices and help more students succeed in becoming scientifically literate citizens.

M.Ed. (Education)
This study is an analysis of Grade 9 Natural Sciences textbooks for their representation of the nature of science. The textbooks analysed are CAPS compliant and approved by the Department of Basic Education. Like any other modern education system in a democratic dispensation, the South African education system has undergone several curricular changes post- independence (1994). These changes have been due to, but not limited by, factors pertaining to political and economic reforms. Curricular revisions have spanned a period of almost 20 years, commencing with Curriculum 2005 (C2005) to the current revised Curriculum and Assessment Policy Statements (CAPS). Science curriculum documents subscribe to the tenets of the nature of science (Lederman, 2007). Bell (2008) suggests that science is best defined by its characteristics, otherwise known as the tenets of NOS. Eleven key aspects of NOS that are intricately related to the basic tenets of science derived by Lederman (2007) form the analytical framework used in this study. The aspects are: Empirical; Inferential; Creative; Theory-driven; Tentative; Myth of the scientific method; Scientific theories; Scientific laws; Social dimensions of science; Social and cultural embeddedness of science and Science vs. pseudoscience. These aspects further formed a detailed scoring rubric to record the extent to which NOS is represented in the units of analysis, which comprise complete paragraphs, activities, worked examples, figures with captions, tables with captions, charts with captions, and marginal comments of the sampled topics ...

Abstract:
M.Ed. (Science Education)
The nature of science (NOS) remains a problematic construct, which many science teachers do not address in their science teaching. This is owing to an uninformed understanding of the NOS by teachers, who therefore do not include NOS aspects in their science teaching. It is, however, imperative to introduce learners in the Intermediate Phase to NOS elements because it is during this phase that they formally learn science Although there is no specific definition of the NOS, there are guidelines in the framework provided by Chiappetta, Fillman and Sethna on the NOS elements that should be included in science textbooks. The NOS framework for science textbook analysis comprises four themes: Science as a body of knowledge, Science as a way of investigating, Science as a way of thinking and the Interaction among Science, Technology and Society. My study focuses on the analysis of workbooks in the Intermediate Phase Natural Sciences and Technology that were distributed by the South African Department of Basic Education during 2013. These workbooks were distributed as part of the implementation of the Curriculum and Assessment Policy Statements (CAPS) in the Intermediate Phase. The workbooks are a combination of textbook and writing book. These workbooks contain ample information about science concept knowledge and colourful illustrations of real life science phenomena. The NOS units of analysis as stipulated in the NOS framework by Chiappetta et al., were identified for the content analysis of science textbooks, in this case science workbooks. As part of the process of content analysis, a qualified science teacher and I analysed the identified pages in each of the six workbooks from Grades 4 to 6. The overall agreement of codes indicated that the NOS themes are substantially covered in the Natural Sciences workbooks, especially the theme Science as a way of investigating and Science as a body of knowledge. The NOS theme Science as a way of thinking receives more coverage than the NOS theme Interaction among Science, Technology and Society. The latter theme was poorly covered in the identified pages of analysis from the six different workbooks. It is suggested that future writing of science textbooks, especially in the Intermediate Phase, should cover all four NOS themes equally. This could assist Intermediate Phase learners in gaining an informed understanding of the nature of science in order to make educated decisions in the scientific enterprise as adults.

The main purpose of this research is to investigate undergraduates’ epistemological beliefs about natural science and social science. Most studies related to epistemological beliefs of science (EBS) lack of consideration from conceptual frameworks of philosophy of science. Besides, in previous studies, “science” usually means “natural science” but not refers to “social science”. Moreover, the relationships between learning motivation and EBS of Chinese students need to be explored further from the perspectives of culture and history. In order to investigate these issues, the present research contains three studies. In study 1, a scale of EBS based on concepts of philosophy of science was developed. The scale was composed of three epistemological beliefs: “rationality and objectivity”, “realism”, and “induction”. In study 2, the scale was adopted to measure 252 undergraduates’ epistemological beliefs about natural science and social science. Results of the 2 (majors of students: natural/social sciences) x 2 (areas of beliefs: natural/social science) MANOVA indicate that: (1) All three epistemological beliefs on natural science are higher than those on social science; (2) epistemological beliefs of “realism” and “induction” among students major in natural sciences are higher than those among students major in social sciences; (3) majors of students and areas of beliefs have interaction effects on beliefs of “rationality and objectivity” and “reality”. In study 3, the relationships among students’ belief of pragmatism, EBS and learning interest in natural and social science were explored. The results of structural equation model show that, for natural science, students’ EBS positively mediate the relationship between their belief of pragmatism and learning interest. However, for social science, students’ belief of pragmatism is negatively correlated with their learning interest. Furthermore, only the belief of “realism” is positively correlated with students’ learning interest in social science.

The potential for South African science teachers to become powerful agents of transformation needs to be explored. Speaking of Fensham's (2002) term “educo-politics” Aikenhead (2010) argues that, "all science teachers are constantly engaged in ‘educo-politics'” (Aikenhead, 2010:615). In this study I attempted to uncover some of the socially critical aspects of science and society related themes. This study investigated how science and society themes outlined in the Natural Sciences Curriculum and Assessment Policy Statement (CAPS) (Department of Basic Education [DBE], 2011) are understood and valued by teachers. The study provides an account of how science teachers under the direction of the curriculum statement conceptualise the pedagogical use, and social value, of Specific Aim 3 in their regular teaching of Grade 9 Natural Sciences. The Science-Technology-Society- Environment (STSE) currents presented by Pedretti & Nazir (2011) provided a theoretical framework from which this inquiry was conducted and structured. This was a qualitative, small-scale study limited to 32 participants. The theoretical foundation of this study was influenced by the ideology and pedagogical frameworks which underpin science and society philosophies and movements in science education. An evaluation of the Natural Sciences CAPS (DBE, 2011) using such frameworks informed the development of the two research instruments used. A questionnaire was administered to 32 Grade 9 Natural Sciences teachers from government schools in the Johannesburg-West and Johannesburg-North districts in Gauteng. Three of the questionnaire participants were then interviewed using a semi-structured interview schedule. The participants varied in age, race demographics, distribution of home languages, professional qualifications and years of teaching experience. The schools where participants teach were varied in terms of demographics and available resources. The study found that participants did not communicate a clear understanding of the principles which form science and society in the Natural Sciences CAPS. Time constraints, deviation from science content and limited usefulness for science learning were commonly cited to justify limited science and society practices. Furthermore, participants regularly made statements which communicated their belief in the superiority of science in terms of its explanatory value. In this regard participants showed insensitivity to the cultural barriers students may experience when learning science. This study has contributed to our understanding of how South African science teachers conceptualise and use science as society themes as outlined in the Grade 9 Natural Sciences CAPS. The findings of this study confirmed that the effects and consequences of the prescriptive elements and nature of the Natural Sciences CAPS (DBE, 2011) need to be critically evaluated. Although curriculum reform in South Africa was intended to empower teachers in their decision-making about what and how to teach, over-reliance on work schedules and Learning Support Materials (LSMs) results in the constriction of teacher agency (Stoffels, 2008). Such tendencies were observed in this study and hence it is suggested that this aspect of teacher agency be explored in further research.

This research study focusses on assessment in the Natural Sciences learning area in grades 8 and 9. The aspect under focus is the extent to which educators can apply assessment methods, tools and techniques in this learning area. Outcomes-based education makes use of outcomes-based assessment which incorporates different methods of assessing learners. This study is concerned with the assessment practices of educators in the classroom. The literature examined looks at what is science?, what is assessment?, assessment in outcomes-based education and outcomes-based assessment in the Natural Science learning area. Both quantitative and qualitative methods of data collection were used in this study. The research instruments used were questionnaires, lessons observations, interviews and analysis of learner portfolios. As a research strategy, questionnaires were administered and analysed; assessment lessons were observed and analysed against principles for outcomes-based assessment; interviews were held with educators, subject advisor and OBE facilitator and learner portfolios were analysed in order to validate data gathered. The findings of the study revealed that educators have begun assessing using the outcomes-based assessment model, however, they are assessing on a very superficial level. The assessment tools, techniques and methods available to educators are not being used properly. It was found that the reason for this was that educators do not fully understand how to assess outcomes and they are not familiar with the assessment criteria. Certain assessment methods like self - and peer - assessment were totally neglected. Educators did not know how to use rubrics and rating scales when assessing learners. From the evidence in the learners’ portfolios, it was found that there is still an over-reliance on tests and that teacher assessment is the dominant assessment method. From the lesson observations it was found that content of the Natural Science learning area was not being adequately covered. In addition, Physical Science sections of the curriculum were deliberately not taught due to inexperience by educators in this field. The lesson observations also revealed that practical work in the form of experiments, observations and investigations was limited and in many cases not done at all. Educators cited lack of experience and resources. It was found that educators over-used textbooks and relied on them as the only source of scientific information. Planning of assessment was also another key area that needed attention.

Abstract:
The introduction of evolution in the ‘new’ Grade 12 life sciences curriculum in 2008 has created many challenges for life sciences teachers. The curriculum requires teachers to integrate evolution in all aspects of their teachings. The literature reveals that many life sciences teachers teach the concept of evolution in isolation and fail to integrate the topic as the underlying principle of Biology. Various studies conclude that teachers’ understandings and beliefs about the NOS no doubt influence their classroom instruction. This study explores life sciences teachers’ understanding of the NOS when teaching the theory of evolution. The NOS is used as the framing concept of the study. My research is a case study of three experienced life sciences teachers. Data was obtained from questionnaires, classroom observations and interviews with the teachers. This data provided valuable insight into the teachers’ understanding of the NOS as well as the way in which this understanding influences their pedagogical practices. Furthermore I was able to develop some understanding of why teachers teach evolution in the way that they do. The instruments were analysed qualitatively. The findings were reported as narratives and reveal that the teachers have different levels of understanding of the NOS. These different understandings have a profound influence on their understanding of evolution, however their understanding of the NOS did not have the same effect on the manner in which they taught evolution. While all three teachers had some misunderstandings, two teachers were able to teach evolution without demonstrating these misconceptions, while one teacher was not. Furthermore, there are also a number of additional factors such as exam-driven approaches, teacher identity, controversy surrounding the theory of evolution, and finally, lack of resources that impact negatively on the way evolution is taught. In conclusion I offer strategies to improve life sciences teachers’ understanding of the NOS and evolution and highlights areas for further research.

Abstract:
This study analyzed representations of Nature of Science (NOS) and Indigenous Knowledge Systems (IKS) in three South Africa Grade 9 Natural Science textbooks. The textbooks were purposefully selected from a possibility of ten textbooks available on the public market and used in science classrooms in the Gauteng Province of South Africa. The aim of the analysis was to determine the extent to which both NOS and IKS were represented and to ascertain whether the representations were: naïve or informed; and implicit or explicit. The content analysis of the textbooks was based on adaptations of analytical frameworks developed by Akerson, Abd-El-Khalick and Lederman (2000) for NOS and Ninnes (2000) for IKS, respectively. For NOS the analysis focused on seven tenets, which are; science is empirical, the difference between observation and inference, functions and relations between theories and laws, the role of creativity and imagination in science, the tentativeness of scientific knowledge, the social and cultural embeddedness of the scientific process, and subjectivity of science. The analysis for IKS representations focused on four pillars of IKS which are; indigenous legends and myths, indigenous technology, indigenous knowledge of the natural world, and indigenous social life. It was found that, for the NOS, in all the three textbooks, only the empirical nature of science and observation and inference are represented to a considerable extent and mainly in a naïve and implicit manner. The other investigated tenets are either minimally represented or not represented at all. Representations of IKS in the three textbooks were also found to be very minimal and mainly naïve and implicit. It is concluded the selected science textbooks do not respond well to the NCS mandate of integrating NOS and IKS into mainstream science education. Recommendations for improving integration of NOS and IKS into the school science curriculum are suggested for textbooks authors, curriculum developers and science educators.

Abstract:
M.Ed. (Science Education)
The South African current school curriculum, namely the National Curriculum Statement, is underpinned by outcomes-based education. The subject Biology (in the Nated 550 curriculum) has been changed to “Life Sciences” and the learning outcomes for Life Sciences are representative of the four themes of the Nature of Science (NOS), namely, science as a body of knowledge, science as a way of investigating, science as a way of thinking, and the interaction of science technology and society. The many changes made from the previous curriculum that accompanied the new curriculum left many teachers reliant on textbooks to plan, guide and inform their teaching and learning activities in the classroom. My study is concerned with the representation of the NOS in Grade 10 South African Life Sciences classrooms. I have conducted my study in two phases. The purpose of Phase One was to analyse three Grade 10 Biology textbooks and three Grade 10 Life Sciences textbooks for the representation of the NOS. A qualitative content analysis methodology was used in the analysis of textbooks, and my study adopted a textbook analytical tool designed by Chiappetta, Sethna and Fillman (2004), using the four broad NOS themes of the mentioned above. The purpose of Phase Two of the study was to observe how teachers use Life Sciences textbooks in their teaching in order to infuse the NOS. A qualitative interpretive case study was the selected methodology for this part of the study. Three practicing Life Sciences teacher-participants were invited to an in-depth interview and a lesson observation each. The lesson observations and the interviews were audio-taped and transcribed. The open-coding method was used where the predetermined codes of the NOS were assigned to extracts of the transcriptions. Qualitative data analysis techniques based on the principles of Framework Analysis (Ritchi & Spencer, 1984) were used in Phase One and Phase Two of my study. There are five steps in Framework analysis, namely, (i) familiarization, (ii) identification of a thematic framework, (iii) indexing (open-coding method), (iv) charting, and (v) mapping and interpretation.

Abstract:
M.Ed.
The teaching of writing skills applicable to the content subjects in the English second language classroom is a recent concern. The concern is raised by the emphasis which the communicative approach places on the integration of skills (Kilfoil and Van der Walt, 1997:263), which many teachers seem to ignore. This neglect is seen in the leaners' poor essays which they write both in the English second language classroom and in their content subjects. It should be emphasised that teaching writing skills does not only mean teaching learners how to write compositions and letters, as is usually done in the language classroom, but also implies teaching them how to write expository texts in other subjects. The focus of this research is a group of learners from historically black secondary schools in this Province who had failed matric several times and were admitted to various Colleges of Education in the Northern Province to be offered a Finishing Programme. These learners seem to be `underprepared' in as far as expository writing is concerned. Miller (1989:158) defines the concept of `underpreparedness' in educational terms as the gaps that the learners have in their knowledge which require help in filling in blank spaces. The finishing learners at the Colleges in the Province constitute a small group among thousands of matric pupils who are underprepared for matric.

Abstract:
Locke was a sceptic about the possibility of scientific knowledge of corporeal substance. Scientific knowledge is knowledge which is certain, universal, and instructive. According to Locke, to have certain and instructive knowledge of natural kinds (universal knowledge about species of corporeal substances) requires knowledge of the real essence of natural kinds. Since a real essence is the foundation for the properties a thing has, it must be known before a deduction of the properties can be done. Locke did not believe that it was possible for humans to know the real essence of corporeal substances. In my thesis, I provide an explanation for why he held these views. As my work shows, knowledge of the real essence of a natural kind is an involved process that requires first knowing the nominal essence of the natural kind, and then knowing the inner constitution of each member of the kind, knowing which aspect of the inner constitution of each member correlates to the overlap of properties used to delineate the natural kind, and finally, knowing how that aspect, which is the real essence of the natural kind, produces the properties it does. Without knowledge of the mechanics of how the physical real essence produces the mental ideas we cannot know whether the connection between the real essence and the properties is a necessary connection or a mere correlation. Unless we know why there is a connection, we cannot know, with certainty, that the connection will hold in the future or for other like configurations. Locke relies on the mind-body problem to explain why we cannot know the mechanics behind the connections. The mind-body problem has not been given appropriate emphasis in Lockean study. And yet it is uniquely capable of handling the two claims Locke makes about natural science: (1) our knowledge of corporeal bodies can never qualify as scientific knowledge and (2) our knowledge of corporeal bodies can be improved in ways that are useful to human life.
