In this thesis, I attempt to develop the rudiments of a ’practice’ conception of scientific knowledge and activities as the basis for a suitable methodology for Science and Technology Studies. In order to do this, I examine the methodologies proposed by two sociologists who can be very broadly construed to be working within the tradition of the "Sociology of Scientific Knowledge’, Harry Collins and Steve Woolgar in the context of their application to a specific case, and attempt to develop an alternative conception by contrast. The thesis is structured as follows. I begin by describing Collins’ and Woolgar’s methodologies for the analysis of scientific knowledge development in some detail in Chapter One. In Chapter Two, I examine the application of these methodologies to the ’computer models of scientific discovery’ case (the case is of some interest because it is held to ’refute’ the possibility of the sort of analysis of scientific activities that Collins and Woolgar propose). I then use the material of the first two Chapters in Chapter Three to diagnose the shortcomings of Collins’ and Woolgar’s methodologies as illustrated by their application to the computer models of discovery case. This sets the stage for an alternative analysis of the computer models case which does not suffer from these shortcomings in Chapter Four. Finally, I develop a practice-based conception of scientific knowledge development in Chapter Five (which I derive from the material of Chapters One through Four), contrast it with the methodologies of Collins and Woolgar, and use it to illustrate and evaluate my alternative analysis. / Master of Science

Thesis (MEd)--Stellenbosch University, 2012. / Includes bibliography / ENGLISH ABSTRACT: The political and social changes that occurred after 1994 in South Africa, inevitably led to the emergence of a new educational era. Life Orientation (LO) was introduced as a new learning area within the Revised National Curriculum Statement (RNCS) and seeks to preventatively empower learners to take up their legitimate place as citizens within the national and international society (DoE, 2003:2). LO cannot only be liable for the holistic development of individual learners. The community in which learners grow up are faced with unique challenges that will inescapably influence their development. I highlight the influence of “Ubuntu” and “Ukama” on the process of becoming of each individual and therefore use the ecosystemic perspective as a theoretical framework for this study. I reflect on my own experiences within the LO classroom that led to the creation of fictional characters and case studies as a teaching strategy. In this study I distinguish between case study as a teaching strategy and a research methodology. I determine the lived experiences of Grade 8 learners in a secondary school where this teaching strategy was used within the LO classroom. A case study as research methodology is used where qualitative data was produced through personal documentation. A random sample of ten participants from the case study is used to obtain a thorough understanding of their lived experiences. Qualitative data was further produced by twenty individual and two focus group interviews with the sample group. I used the constant comparative method to ensure that I identify the units of meaning and discuss the findings on the basis of three categories. First, the data indicated that the participants found guidance through the case studies of the characters. Secondly, it appeared that the experiences of the characters influenced the participants’ decision making processes. Thirdly, the data indicated that participants used this teaching strategy as a platform to voice their own personal emotions and experiences. On the basis of Gilles Deleuze (in Wallin, 2010) and Magdeleine Grumet (1981) this study emphasizes the potential role that an evolving, active form of curriculum can play in the becoming processes of each individual learner and teacher. I conclude by recommending that uniqueness and diversity must be encouraged within the classroom to ensure that curriculum will not be a homogeneous policy document, but that it will be active and developmental in nature. I use the work of Wallin (2010), Sutton and Martin-Jones (2008) and Grumet (1981) to offer new insights about the pedagogical making process within the South African context. / AFRIKAANSE OPSOMMING: Die politiese en sosiale veranderinge wat na 1994 binne Suid-Afrika plaasgevind het, het onvermydelik gelei tot die ontstaan van ʼn nuwe opvoedkundige era. Lewensoriëntering (LO) was as ʼn nuwe leerarea binne die Hersiene Nasionale Kurrikulumverklaring (HNKV) bekendgestel en poog om op ʼn voorkomende wyse leerders te bemagtig om hul geregmatige plek as burgers binne die nasionale, sowel as internasionale samelewing op te neem (DvO, 2003:2). LO kan nie alleen aanpreeklik gehou word vir die holistiese ontwikkeling van individuele leerders nie. Die gemeenskap waarbinne die individuele leerders groot word het sy unieke uitdagings en sal daarom onwillekeurig hierdie ontwikkelingsproses beïnvloed. Ek beklemtoon daarom “Ubuntu” en “Ukama” se invloed op die individu se wordingsproses en gebruik die ekosistemiese perspektief as ʼn teoretiese raamwerk vir hierdie studie. Ek reflekteer oor my eie ervarings binne die LO-klaskamer wat aanleiding gegee het tot die ontstaan van fiktiewe karakters en gevallestudies as onderrigstrategie. In hierdie studie onderskei ek tussen gevallestudies as onderrigstrategie en navorsingsmetodologie. Ek bepaal die geleefde ervaring van graad 8-leerders in een sekondêre skool waar dié onderrigstrategie in die LO-klaskamer gebruik word. ʼn Gevallestudie word as navorsingsmetodologie gebruik waar kwalitatiewe data deur persoonlike dokumentasie geproduseer is. Ten einde ʼn deeglike begrip te verkry van die gevallestudie se geleefde ervaring is ʼn ewekansige steekproef van tien deelnemers gebruik. Kwalitatiewe data is verder deur twintig individuele en twee fokusgroeponderhoude met hierdie steekproef geproduseer. Ek het deurgaans die konstante vergelykende metode om eenhede van betekenis te identifiseer gebruik en bespreek my bevindinge aan die hand van drie kategorieë. Eerstens dui die data aan dat deelnemers leiding uit die gevallestudies van karakters ontvang het. Tweedens blyk dit of die ervarings van die karakters die deelnemers se besluitnemingsproses beïnvloed het. Derdens dui die data aan dat deelnemers hierdie onderrigstrategie as ʼn platform gebruik het wat hulle in staat gestel het om uiting aan hul persoonlike emosies en ervarings te gee. Ten slotte beklemtoon hierdie navorsingstudie aan die hand van Gilles Deleuze (in Wallin, 2010) en Magdeleine Grumet (1981) se werk die potensiële rol wat ʼn ontwikkelende, aktiewe vorm van kurrikulum in die wordingsproses van elke individuele leerder en opvoeder kan speel. Ek beveel daarom aan dat uniekhede en diversiteit binne die klaskamer aangemoedig moet word ten einde te verseker dat kurrikulum nie as ʼn homogene beleidsdokument aanvaar word nie, maar dat dit aktief en ontwikkelend van aard sal wees. Ek gebruik die werk van Wallin (2010), Sutton en Martin-Jones (2008) en Grumet (1981) om nuwe insigte rondom die pedagogiese wordingsproses binne die Suid-Afrikaanse konteks aan te bied.

The purpose of this study was to determine if leadership training, given to informal leaders, had a positive effect on manufacturing productivity. The leadership attributes of informal leaders were assessed using the Leader Attributes Inventory (LAI). Furthermore, the performance of informal leaders was measured using the Leader Effectiveness Index (LEI). Non-management employees from various departments in a manufacturing facility were placed in one of four experimental groups. A Solomon four-group experimental design was employed. A one-group pretest-posttest design was used to control threats to internal validity. The one-way analysis of variance procedure (ANOVA) was used to determine if there were statistically significant increases in manufacturing productivity of informal leaders. Findings suggested that training increased the manufacturing productivity of informal leaders. The increased productivity indicated that leadership training could help manufacturing facilities increase their productivity without capital expenditures. Findings did not indicate a statistically significant difference in leadership attributes. Findings also suggested there were no significant differences in the manufacturing productivity between employees with high leader attributes and low leader attributes. Based on this study, leadership training, given to non-management employees, may yield gains in manufacturing productivity.

Continuing education advances society. For every student, our educational system should provide a seamless transition from one level to the next until a degree or certificate is earned that reflects a mastery of skills needed to secure employment. This helps prepare each individual for a successful life after exiting the educational system and greatly benefit our society. Today, however, many students graduating from high schools are not ready for a postsecondary education. Transitioning students from high school to college is a complex process that requires many different approaches. Students making this transition are finding it more difficult to enter and succeed at a higher level of education because of the complexity of this process. Preparing students for postsecondary options is critical for every student. Students from low-income families and some ethnic and racial minority groups are most dependent on the ability of their high school to prepare them properly for college success (Conley, 2010). In what ways can schools better prepare students for postsecondary success? This study focuses on the creation of a Postsecondary Readiness Guidebook (PRG) which provides a comprehensive approach to help educational leaders prepare students for postsecondary success. The guidebook uses a problem-based learning design and follows the research and development process. The guidebook was field tested by educational leaders in a K-12 public school though a workshop using a qualitative methodology. During the field-testing of the guidebook, data were collected through assessments, interviews with educators, and questionnaires completed by educational leaders at the school. Data were analyzed using inductive coding, facesheet coding, enumeration, and typology. The findings of the study reveal that using a guidebook with a comprehensive approach to postsecondary preparedness can help school leaders prepare students for postsecondary success. Educational leaders in the school collectively focused on best practices and programs aimed at preparing students for postsecondary options through the use and interaction of the PRG. The guidebook gave them a compass for which to navigate the complex process of preparing students for postsecondary success.

This thesis reports on a longitudinal, mixed-methods study of the relationships between informal (i.e. out-of-class) second language (L2) contact, vocabulary-related strategic behaviour and vocabulary gain in a study abroad context. The study addressed three main gaps in knowledge that arose from analysis of the literature: (1) the evidence of informal L2 contact was largely unreliable, ungeneralisable, or both; (2) the evidence of vocabulary-related strategic behaviour in informal L2 contact was neither context nor task specific; and (3) there was no evidence of the interplay between informal L2 contact, vocabulary-related strategic behaviour and vocabulary gain in a study abroad context. The sample (n=241) were adults undertaking a study abroad experience (SAE) in England, who comprised a range of nationalities and first language backgrounds and for whom the majority of the SAE was spent outside of the classroom. A vocabulary test was administered at the beginning and end of the SAE. A questionnaire was administered during the SAE to determine the most highly identified with informal L2 contact scenarios and out-of-class vocabulary-related strategies. Subsequently, an innovative research tool comprising computer-based simulations of the most identified with scenarios was developed and used as the stimulus in semi-structured interviews to capture task and/or context-specific vocabulary-related strategic behaviour. Analysis grouped participants by length of stay and location. The most highly identified with informal L2 contact scenarios involved participants seeking information from external sources, such as interlocutors, posters or websites. The vocabulary-related strategies most highly identified with by the sample pertained to the use of a newly encountered lexical item; that is, they were strategies in which the learner used or prepared to use a lexical item that they had decided to engage with strategically. The strategic behaviour manifested in response to the simulation tool (the 'OWLS') provided strong evidence in support of the fundamental considerations of task, context and intention in strategy-based research. Regression analysis revealed that informal L2 contact scenarios that were less strategically prohibitive and strategies that were less context-dependent were predictors of vocabulary gain. The pedagogical implications of these findings are far- reaching in terms of preparing L2 learners for informal contact on a SAE and guiding their manipulation of that contact for maximum linguistic gain.

The study was an investigation into the teaching decisions that mathematics teachers make over time. I view a mathematics classroom as a didactical system of teacher, learners and content within an educational institution, where content is the material that brings teachers and learners together. Within such a system I view the teacher's role as making content available to learners. Prior research has often investigated the teacher's role by comparing teaching practices nationally or internationally, but these comparisons have tended to use the lesson as the unit of analysis. I propose that how teachers make content available can change over the course of a series of lessons and so my study used the lesson series as the unit of analysis. I purposefully designed the study so that it involved four cases, which allowed me to explore the role of the teacher and the topic in how content was made available. To investigate how teachers made content available to learners in each case, I developed an analytical approach from which I could study the modes of teacher interaction that featured across the lesson series, the forms of mathematical content made available and the sequencing of these forms. Attending to forms of content - rather than content itself - allowed for comparison of teaching of different topics. This original analytical approach represents a contribution to both mathematics education and mixed methods research. Within this small sample of cases, quantifiable differences were identified in how content was made available between classwork and seatwork, from lesson to lesson and between cases. Between-case differences in the nature of teaching 'between-the-desks' during seatwork were also identified. These differences illuminated teaching decisions to which teachers and classroom researchers may not routinely attend. The findings therefore contribute - and identify additional lines of enquiry that might contribute further - to a more extensive understanding of teaching practices.

This research explores the multifaceted benefits that accrue from learning within an international, experiential context. It uses a qualitative, case study approach employing pre and post surveys, in-situ observations, and semi-structured photo-elicitation interviews to analyze the Center for Geography Education in Oregon’s (C-GEO) 2013 Overseas Teacher Institute--a professional development program that took 11 teachers to Russia, Mongolia, and China for a total of 17 days (plus two additional travel days) to learn about the cultural and physical geography of each place. The focus of the research is two-fold and examines processes involved in gaining, synthesizing and applying 1) a sense of place (the emotional ties between people and place), and 2) geo-literacy. The results of this study provide evidence that intensive professional development programs can increase teachers personal and professional knowledge, change their instructional practices, and may lead to improved student learning outcomes.

Thesis (MEd) -- Stellenbosch University, 2012. / ENGLISH ABSTRACT: This study explored the views of thirteen youth at Victoria High School about what they regarded as achievement and how this influenced their lives and what they thought about their futures. The starting premise of the study was that all learners think about achievement. The goal of the study was thus to show how different learners connect this understanding of achievement with their respective aspirations and the kinds of social and schooling worlds they inhabit. The key contribution of the study is the ways it links the social, cultural, and economic worlds of each of the thirteen learners to what they say about what they do and what they want to do, who they are and who they want to be, and what they think they do and what they think they want to do. The study shows that the life-worlds of each of the learners are significantly different yet the ways they go about making sense of that world are fairly similar. In that regard it is shown that the school, and what learners, parents and educators think it is and does, plays a crucial role in the sense-making process. As Berkhout (2008) notes, the different contexts that shape the lives of individuals are not simply external forces but rather are integral parts of their identity-making process. The study used the work of Pierre Bourdieu and Arjun Appadurai to bring together a framework by which to understand what learners said about their worlds and their aspirations, as well to develop a narrative that showed the rich and complex ways in which learners engaged with their realities. The study followed an interpretive qualitative approach to explore the issue of achievement and based its arguments on interviews conducted with thirteen youth between the ages of fifteen and seventeen years old. In this regard, a key finding was that learners approached the notion of achievement in developmental, cumulative, and progressive ways. These views included wanting to be popular, gaining new knowledge, preparing for future material acquisition, developing skills to lead decent lives, acquiring happiness, developing the ability to overcome their challenges and circumstances, and gaining skills and recognition that set up their futures. Five staff members at Victoria High school were also interviewed for their views of the schooling context and the kinds of cultures and legacies that framed their practice. / AFRIKAANSE OPSOMMING: Die tesis is gefokus op die denke van dertien studente van Victoria Hoërskool aangaande die nosie van prestasie, en hoe hierdie denke hul lewens beïnvloed sowel as wat hulle dink van hul toekoms. Die vertrekpunt van die verbande studie was dat alle leerders oor prestasie dink. Die doel van die tesis (daaruitvoortspruitend) was dus om aan te toon hoe verskillende leerders ʼn verband aanlê tussen hul beskouing van prestasie, hul aspirasies en die maatskaplike- en skoolwêrelde wat hul beleef. Die kern bydrae van die tesis is die verbande wat gemaak is in die verbande studie tussen die sosiale, kulturele en ekonomiese wêrelde van elkeen van die dertien leerders ten opsigte van hul beskouing aangaande wat hulle doen en wil doen, wat hulle is en wil wees, en wat hulle dink hulle doen en wil doen. Die tesis toon aan dat die leefwêreld van elk van die leerders merkbaar verskillend is, maar dat die wyse waarop hulle betekenis gee aan hul leefwêreld tog redelik ooreenstem. In hierdie verband is dit getoon dat die skool, en wat leerders, ouers en onderwysers daaromtrent dink, ʼn kardinale rol speel in hul betekenisvormingsproses. Berkhout (2008) voer in hierdie verband aan dat die verskillende kontekste wat die lewens van individue vorm nie slegs eksterne magte is nie, maar eerder integrale dele van hul identiteitsvormings proses is. Die studie maak gebruik van die werk van Pierre Bourdieu en Arjun Appadurai om ʼn raamwerk te ontwikkel om leerders se beskouinge van hul wêrelde en aspirasies te verstaan, sowel as om ‘n narratief te ontwikkel wat die ryk en komplekse wyses waarop leerders met hul realiteite omgaan, aan te toon. Die tesis, en verbande studie, het ʼn interpretatiewe, kwalitatiewe benadering gevolg om die idee van prestasie te verken en het die tesis argumente baser op onderhoude met dertien leerders tussen vyftien tot sewentienjaar oud. ʼn Kernbevinding in hierdie verband was dat leerders die idée van prestasie op ontwikkelings-, kumulatiewe- en progressiewe wyses benader. Beskouinge van leerders in die verband sluit onder andere in, die behoefte om populêr te wees, die verkryging van nuwe kennis, voorbereiding om materiële goedere in die toekoms te bekom, die ontwikkeling van vaardighede noodsaaklik vir ʼn ordentlike lewe, die strewe na geluk, die ontwikkeling van die vermoë om hul uitdagings en omstandighede te oorkom, en die ontwikkeling vaardighede en erkenning noodsaaklik vir hul toekoms. Onderhoude is ook gevoer met vyf personeellede van Victoria hoërskool om hul beskouinge ten opsigte van die skoolkonteks en die soort kulture en erfenisse wat hul praktyk informeer te bepaal.

This qualitative study was conducted in a large north Texas school district. The subjects were four elementary teachers who had previously attended a summer aerospace education workshop. The researcher observed in each classroom during science instruction and other areas where aerospace concepts might be taught to determine material usage, practices, and perceptions associated with teaching aerospace. The teachers' lesson planbooks, textbooks, and supplementary materials were also examined by the researcher. Interviews were conducted with each teacher's principal and the district science coordinator to determine their effects on the practices and perceptions of the subjects.
