Além disso, esse processo permite realizar a configuração desses artefatos de requisitos para um produto da LPS, com base no atendimento de requisitos nãofuncionais (RNFs). Contudo, essa configuração é realizada sem considerar o estado do contexto do ambiente no qual a aplicação gerada será implantada. Isso é uma limitação, pois uma configuração pode não atender as necessidades do stakeholders. Por outro lado, o processo E-SPL (Early Software Product Line) permite configurar o modelo de objetivos de um produto visando maximizar o atendimento de RNFs e levando em consideração o estado do contexto. Para superar a limitação do processo GS2SPL, o presente trabalho propõe uma extensão do processo GS2SPL para incorporar a atividade de configuração do E-SPL. O novo processo é chamado de GSC2SPL (Goals, Scenarios and Contexts to Software Product Lines), o qual possibilita a obtenção do modelo de features e cenários de caso de uso, a partir de modelos de objetivos contextuais. O processo também permite realizar a configuração desses artefatos de requisitos com base nas informações sobre o contexto e visando aumentar o atendimento dos requisitos nãofuncionais. O processo é apoiado pela ferramenta GCL-Tool (Goal and Context for Product Line - Tool). O processo foi aplicado à especificação de duas LPS: o Media@ e o Smart Home. / GS2SPL (Goals and Scenarios to Software Product Lines) is a process aimed at systematically obtaining a feature model and the specification of use case scenarios from goal models of a Software Product Line (SPL). Moreover, this process allows configuring specific applications of an SPL based on the fulfillment of non-functional requirements (NFRs). However, this configuration is performed without considering the context state in which the system will be deployed. This is a limitation because a configuration may not meet the needs of stakeholders. On the other hand, E-SPL (Early Software Product Line) is a process that allows configuring a product aimed maximizing the fulfillment of NFRs and taking into account the context state. To overcome the limitation of the GS2SPL process, in this work we propose extension of the GS2SPL process, to incorporate the configuration activity of the E-SPL. The new process is called GSC2SPL (Goals, Scenarios and Contexts to Software Product Lines), which allows obtaining a feature model and use case scenarios from contextual goal models. The process will also allow the configuration of such requirements artifacts based on the information about the context and aiming to maximize the fulfillment of non-functional requirements. The process is supported by the GCL-Tool (Goal and Context for Product Line - Tool). The process was applied to the specification of two LPS: Media@ and the Smart Home.

Os diferentes pontos de vista desses estudantes foram identificados através do uso da Metodologia "Q". A partir de discussões em grupos focais, foram selecionadas 57 afirmações sobre o tema proposto para compor a Amostra "Q". A Distribuição "Q" foi, então, feita por 65 participantes e foram identificados cinco pontos de vista distintos. Os sujeitos do primeiro ponto de vista, os "Valorizadores da Prática", são pessoas que acreditam na prática da língua de variadas maneiras. Os sujeitos do segundo ponto de vista, os "Valorizadores da Comunicação", acreditam que é através da comunicação em viagens para fora do país que se aprende Inglês. Os sujeitos do terceiro ponto de vista, os "Valorizadores da Autonomia", valorizam sua própria autonomia e rejeitam veementemente atividades de caráter obrigatório. Os sujeitos do quarto ponto de vista, os "Externamente Motivados", necessitam de um encorajamento externo e, portanto, valorizam a educação formal e o compromisso com a escola. Os sujeitos do quinto ponto de vista, os "Valorizadores do Esforço", creem principalmente no esforço pessoal e na força de vontade para a aprendizagem da língua. Concluímos que os "Valorizadores da Prática" e os "Valorizadores do Esforço" valorizam o uso de Estratégias de Aprendizagem, enquanto que os "Valorizadores da Autonomia" e os "Externamente Motivados" se apóiam em questões de Motivação. Os "Valorizadores da Comunicação" percebem tanto o valor das Estratégias, como também o da Motivação para a aprendizagem da LE Inglês fora da sala de aula / Abstract: The main objective of this study is to verify perceptions of High School students in two private schools located in São Paulo about learning English as a foreign language in informal learning contexts, i.e. outside the classroom. Five different points of view were identified through the use of "Q" Methodology. The 57 statements making up the "Q" Sample were extracted from discussions in focal groups. "Q" Sorting was conducted by 65 students, and five distinct points of view resulted from the factor analysis of the answers. The "Practicing Learners" are students who believe that there are many ways to learn English outside the classroom, for seeing practice in various different forms leads to learning. The "Communicative Learners" feel English can be learned by speaking it while traveling abroad. The "Autonomous Learners" value their autonomy and reject activities they are required to do. The "Externally Motivated Learners" value the responsibilities and motivation furnished by formal education and their commitment to school. The "Hardworking Learners" recognize the importance of personal effort and willpower in learning the language. We concluded that the "Practicing Learners" and the "Hardworking Learners" value the use of Learning Strategies, while the "Autonomous Learners" and the "Externally Motivated Learners" are more influenced by Motivation. The "Communicative Learners" feel a need for both Learning Strategies and Motivation to learn English as a foreign language outside the classroom / Mestrado / Linguistica Aplicada / Mestre em Linguística Aplicada

No. of bitstreams: 1 Daniel Pereira de Oliveira.pdf: 1962605 bytes, checksum: 022c425ec0a87d2146c7cae3f274903b (MD5) Previous issue date: 2006-03-03 / In the current days, the Internet has become the largest information repository available. However, this huge variety of information is mostly represented in textual format and it necessarily requires human intervention to be effectively used. On the other hand, there exists a large set of Web pages that are in fact composed of collections of implicit data objects. For instance, on-line catalogs, digital libraries and e-commerce Web sites in general. Extracting the contents of these pages and identifying the structure of the data objects available allow for more sophisticated forms of processing besides hyperlink browsing and keyword-based searching. The task of extracting data from Web pages is usually executed by specialized programs called wrappers. In the present work we propose and evaluate a new approach to the wrapper development problem. In this approach, the user is only responsible for providing examples for the atomic items that constitute the objects of interest. Based on these examples, our method automatically generates expressions for extracting other atomics items similar to those presented as example and infers a plausible and meaningful structure to organize them. Our method for generating extraction expression uses techniques inherited from solutions for the multiple string alignment problem. The method is able to produce good extraction expressions that can be easily encoded as regular expressions. Inferring a meaningful structure for the objects whose atomic values were extracted is the task of the HotCycles algorithm, that were previously proposed and which we have revised and extended in this work. The algorithm assembles an adjacency graph for these atomic values, and executes a structural analysis over this graph, looking for patterns that resemble structural constructs such as tuples and lists. From such constructs, a complex object type can be assigned to the extracted data. The experiments carried out using 21 collections of real Web pages have demonstrated the feasibility of our extraction method, reaching 94% of effectiveness using no more than 10 examples for each attribute. The HotCycles algorithm was able to infer a meaningful structure for the objects present in all used collections. Its effectiveness, combined with our atom extraction method, reached 97% of structures correctly inferred, also using no more than 10 examples per attribute. The association of these two methods has demonstrated to be extremely feasible. The high number of correctly inferred structures together with the high precision and recall values of the extraction process demonstrates that this new approach is indeed a promising one. / Hoje em dia a Web se apresenta como o maior repositório de informações da humanidade. Contudo, essa imensa gama de informação é formada principalmente por conteúdo textual e necessariamente requer interpretação humana para se tornar útil. Por outro lado, existe uma grande quantidade de páginas na Web que são, na verdade, formadas por um conjunto implícito de objetos. Isso ocorre, por exemplo, em páginas oriundas de sites de catálogos on-line, bibliotecas digitais e comércio eletrônico em geral. A extração desse conteúdo e a identificação da estrutura dos objetos disponíveis permite uma forma mais sofisticada de processamento além da tradicional navegação por hiperlinks e consultas por palavras-chave. A tarefa de extrair dados de páginas Web é executada por progamas chamados extratores ou wrappers. Neste trabalho propomos uma nova abordagem para o desenvolvimento de extratores. Nessa abordagem o usuário se restringe a fornecer exemplos de treinamento para os atributos que constituem os objetos de interesse. Baseado nesses exemplos, são gerados automaticamente padrões para extrair dados inseridos em contextos similares áqueles fornecidos como exemplos. Em seguida, esses dados são automaticamente organizados segundo uma estrutura plausível. Nosso método de geração de padrões de extração utiliza técnicas herdadas de soluções para o problema do alinhamento múltiplo de seqüências. O método é capaz de produzir padrões de extração que podem ser facilmente transformados em expressões regulares. A tarefa de inferir uma estrutura plausível para os objetos extraídos é realizada pelo algoritmo HotCycles, que foi previamente proposto e que foi revisto e ampliado neste trabalho. O algoritmo constrói um grafo de adjacências para esses dados, e realiza nele, uma análise estrutural em busca de padrões que indiquem construtores estruturais como tuplas e listas. A partir de tais construtores, é associado um tipo aninhado aos dados que foram extraídos da página. Experimentos realizados em 21 coleções de páginas reais da Web demonstram a viabilidade do método de extração de valores atômicos, obtendo um desempenho superior a 94% e utilizando no máximo 10 exemplos de treinamento por atributo. O algoritmo HotCycles foi capaz de inferir uma estrutura plausível para os objetos em todas as coleções utilizadas. Seu desempenho combinado com o método de extração de valores atômicos chegou a 97% de estruturas corretamente inferidas com a utilização também até 10 exemplos por atributo. A combinação desses dois métodos demonstrou-se extremamente viável. Os altos índices de estruturas corretamente inferidas juntamente com os elevados índices de precisão e revocação do processo de extração demonstram que esta é sem dúvida uma abordagem promissora.

As reflexões sobre a contemporaneidade sugerem que, na rapidez da pós-modernidade e frente a tantas possibilidades proporcionadas pela multiplicidade de plataformas midiáticas (tradicionais e digitais), muitas organizações, na urgência de comunicar, geram grandes quantidades de informações sem relevância para seus públicos. Limitadas a um modelo pronto e replicadas sem critério, são disparadas para os indivíduos sem considerar os diferentes sujeitos integrantes/construtivos da cultura organizacional e suas histórias, memórias e desejos, e sem enxergar as diversas oportunidades para repensar este processo da comunicação interna. É neste panorama que o presente estudo pretende detectar oportunidades de envolvimento do público interno, assim como a criação de narrativas comunicacionais mais atrativas e bem-sucedidas. Para tanto, busca-se a compreensão da riqueza existente em conteúdos coletados em projetos de memória oral, de cunho participativo e dialógico, como os desenvolvidos com base na contação de histórias sobre as experiências vividas dos funcionários no ambiente organizacional: as chamadas micronarrativas. Este conceito foi desenvolvido sobre as teorias que interpretam as grandes narrativas da modernidade, as quais possuíam uma significativa força na vida das pessoas e serviam como referências para a sociedade, mas que começaram a se enfraquecer a partir do século XX e se perderam na pós-modernidade, quando o foco passou a ser o indivíduo e suas histórias. Dessa maneira, ao verificar, descrever, esclarecer e entender o conteúdo exposto pelos entrevistados em suas micronarrativas organizacionais, é possível refletir como a comunicação interna pode trabalhar de maneira mais efetiva e afetiva para gerar novas narrativas que estimulem envolvimento, reconhecimento, identificação, compreensão e ação de seus funcionários, no lugar das racionalidades, padronizações, efemeridades e excessividades. / Reflections on contemporaneity suggest that in the fleetness of post-modernity and in the presence of so many possibilities offered by the multiplicity of media platforms (traditional and digital), many organizations, in the urgency to communicate, generate large amounts of information with no relevance to their audiences. Limited to a ready template and replicated without criteria, this information is issued to individuals without considering the different members/constructive subjects of organizational culture and their stories, memories and wishes; missing the various opportunities to rethink the process of internal communication. Before this scenario, the present study aims to identify opportunities to involve the internal workforce, as well as creating more attractive and successful communication narratives. To that purpose, we seek a better understanding of the richness in the content of oral memory projects, which nature is participatory and dialogic, such as those developed based on storytelling about the employees\' experiences in the organizational environment: the micro narratives. This concept was developed based on the theories that interpret the grand narratives of modernity, which had a significant influence in people\'s lives and served as references to society, but started weakening in the twentieth century and were dissolved in the post-modernity, when the focus shifted to the individual and their stories. Therefore, when we verify, describe, explain and understand the contents stated by respondents in their organizational micro narratives, it is possible to ponder how internal communications can work more effectively and affectively to generate new narratives that encourage involvement, recognition, identification, understanding and action from the employees, in detriment to rationality, standardization, and ephemeral excesses.

A presente pesquisa de doutorado pretende levantar, catalogar e examinar os vestígios arqueológicos dos contextos funerários, datados entre o intervalo do século XI ao VIII a.C. nos principais sítios da região da Argólida (Mapas 1, 2 e 3), Argos, Tirinto, Asine, Micenas, Náuplia e Lerna. Comparando tais dados entre si, e discutindo-os a partir de fundamentos teórico-metodológicos da Arqueologia das Práticas Mortuárias, objetivamos, por fim, levantar considerações sobre os costumes funerários dessa área, revelando possíveis padrões de enterramento e de comportamento sócio-cultural inseridos nas mudanças políticas ocorridas em um período de longa duração, principalmente, durante o período denominado de Alto Arcaísmo, o século VIII a.C., com o processo de formação da pólis argiva. / This thesis intends to gather, catalogue and analyze the archaeological data from the funerary contexts, dated from the XI to the VIII centuries BC in the main sites of the Argive plain (Maps 1, 2 and 3). Finally, it is also our aim to compare the data collected and discuss them through the theoretical and methodological basis of the Archaeology of Mortuary Practices trying to reach some questions and considerations about the funerary customs and burial patterns of this region and also possible social and cultural behavior characteristic of the shifts occurred mainly during the VIII century BC.

Compte tenu des différences concernant le pilotage de l’éducation au développement durable (EDD) en France et au Chili et la place plus ou moins explicite du mot développement durable (DD) dans les sciences humaines et sociales et les sciences de la nature de ces deux pays, cette recherche tente de repérer la manière dont les enseignants et les élèves, en fonction de ces disciplines, se représentent l’objet DD. Il s’agit de mettre en évidence comment leurs représentations sociales (RS) répercutent dans le processus d’enseignement-apprentissage de cette question socialement vive (QSV). Pour ce faire, nous avons élaboré un dispositif méthodologique qui associe des questionnaires et des entretiens pour les enseignants. Alors que pour les élèves, ce dispositif se base intégralement sur des questionnaires. Nos résultats révèlent l’existence chez les enseignants des deux pays d’une RS du DD emboîtée dans celle d’un environnement-ressource. Cette représentation serait plus marquée chez les enseignants chiliens, en dégageant ainsi une perception plus développementaliste dans leur compréhension des enjeux du DD. Bien que les élèves, toutes classes confondues, partagent une RS ancrée dans la réalisation d’écogestes, la visée développementaliste est aussi présente chez les apprenants chiliens. À la lumière de nos résultats, nous pensons que sans une mise à distance dans la construction du savoir et en écartant les controverses, les pratiques éducatives acquièrent une allure transmissive qui ne favorise pas la compréhension des questions complexes que soulève la mise en place de ce projet planétaire. / Considering the differences in the control of education for sustainable development (ESD) in France and Chile and the more or less explicit place of the word sustainable development (SD) in the humanities and social sciences and natural sciences such two countries, this research attempts to identify how teachers and students, according to these disciplines, will represent the SD object. This is to highlight how their social representations (RS) reflected in the teaching-learning process of this socially controversial issue (QSV). To do this, we developed a methodological device that combines interviews and questionnaires for teachers. As for the students, this device is based entirely on questionnaires. Our results reveal the existence among teachers of both countries an RS SD fitted into that of a resource-environment. This representation would be more pronounced among Chilean teachers, thus generating a developmentalist perception in their understanding of SD issues. Although students of all classes share a RS rooted in the realization of eco-gestures, the developmentalist referred is also present among Chilean students. In light of our results, we believe that without a distancing in the construction of knowledge and spreading controversy, educational practices acquire a transmissive pace that does not promote understanding of the complex issues involved in implementing it global project.

The current study examined the relationship between affect changes or lack thereof when one logs onto Facebook or Yahoo!. Facebook was specifically chosen for examination in the current study due to its widespread use, its vast effect on society, and its unique features that allow users to obtain information and have social interaction at the same time. Yahoo! served as a control due to the fact that it is a highly popular site that has similar features of Facebook without having the social functions. Both sites allow users to observe news that is pertinent and of interest to them and both are popular; the main difference between the two sites is the social component that Facebook can offer that Yahoo! is unable to offer users. Findings suggest that logging onto Facebook increases positive affect and joy, but this is short lived. After a period of time on the website negative affect and anger increase. Further research needs to be conducted in order to understand what activities on Facebook lead to more or less affect modulation and future studies are discussed.

In 1991, one year after the Namibian independence, the Ministry of Education and Culture was organised in six departments and six regional directorates. The regional directorates were established as early as in 1991. The establishment of the regional directorates was the first step towards decentralisation of education management, which took a form of de-concentration. During the late 1990s, the regional directorates were subdivided into thirteen regional education directorates to be in compliance with the central government policy of decentralising functions from the head offices of various ministries to the regional administrations in the thirteen regions. During 2000, the Namibian Ministry of Education introduced cluster-based school management as a decentralisation reform, granting authority and responsibility for managing school supervision and in-service training for school managers and teachers to clusters, to be implemented in all the thirteen education regions. Cluster–based school management reform has been adopted as a strategy for improving school supervision and teaching in Namibia. However, there is little empirical evidence on the effects of school clustering on the quality of teaching in Namibia. This study examined the implementation of cluster-based school management reform in the Namibian primary schools. The specific focus of the study was to assess: (1) the implementation of cluster-based school management reform in the Namibian primary schools; and (2) the relationship between cluster-based school management reform and improving teaching at classroom level. The data for this study were collected through: (1) survey research in thirty-seven primary schools in five regions: Caprivi; Erongo; Hardap; Karas and Kunene, and (2), case studies, based on interviews; focused group discussions; informal conversations; observations; and document analyses in the three primary school clusters in two of the five education regions. The study’s main findings are that the implementation of cluster-based school management reform has been constrained by resource scarcity and reluctance to share resources; potential threat to the authority of school inspectors and school principals; and incongruence between the ideologies existed prior to the introduction of the reform and the democratic ideology. The other main finding from this study is that there is insufficient evidence to show that the teaching methods of teachers who have received support from the school management reform are notably different from those who have not. This study demonstrates a number of obvious missing links between cluster-based school management and improving teaching, because the reform lacks: (1) clarity, guidelines and resources to support and monitor teaching in schools and at classroom level; (2) clarity on the roles and responsibilities of key implementers in improving teachers’ teaching practices; (3) capability to transform school traditions and culture into a culture which transforms teaching in schools; and (4) clarity on how teacher involvement can be utilised to improve teaching in schools. This study concludes that there is no evidence from this study that cluster-based school management reform relates to improving teaching. / Thesis (PhD)--University of Pretoria, 2009. / Education Management and Policy Studies / unrestricted

L'objectif de notre recherche est de tenter d'identifier les compétences professionnelles (Altet, 1996 et 2009) acquises ou en cours d'acquisition des maîtres novices durant leur année de stagiarisation (visée heuristique). Pour ce faire, nous nous inscrivons dans le paradigme écologique ou paradigme de la complexité (Clanet, 1997 ; Piot, 2014). Nous portons un intérêt particulier à l'acquisition des compétences liées à trois dimensions clés que sont la gestion du temps, la tâche et les interactions maîtres-élèves, dimensions étudiées notamment par les chercheurs intégrés au réseau OPEN (Observation des pratiques enseignantes). Nous postulons que le développement professionnel (Wittorski & Briquet-Duhazé, 2010), initié en début de carrière, est variable selon les novices et que cette variabilité est interdépendante du degré de maîtrise des compétences attachées à ces dimensions. Le niveau d'expérience constituant un axe majeur de notre recherche, nous opposerons dans une approche contrastive, l'enseignant stagiaire à l'enseignant expérimenté, évoluant dans des situations similaires. Si nous avons pour ambition de déceler des différences entre les stagiaires en formation professionnelle (variabilité inter-maîtres), nous visons également l'identification des « invariances qui dénotent la présence d'organisateurs des pratiques » (Clanet, 2001). Nous nous efforçons donc de repérer parmi les pratiques enseignantes mobilisées, les organisateurs des pratiques typiques des maîtres « novices ». Pour ce faire, nous recourons à des méthodes mixtes, quantitative (questionnaires) et qualitative (observations et entretiens). Les questionnaires portent sur le niveau de maîtrise des compétences attendues (Référentiel de compétences, 2013) et sur les difficultés potentielles des futurs maîtres. La population enquêtée concerne les stagiaires eux-mêmes (N=178) ainsi que les maîtres d'accueil temporaire (MAT) (N=83) qui les accompagnent. Dans un second temps sont confrontés les deux corpus de représentations pour en évaluer le degré de congruence. Centrées sur trois dimensions organisatrices précédemment déclinées (Clanet, 2010), les observations portent sur six trinômes d'enseignants (un MAT et deux stagiaires N=18) œuvrant dans des classes de cycle III. Nous prenons appui sur la dimension tâche, afin d'analyser les dimensions transversales temps et interactions. Plus précisément, les étapes communes, mises en évidence au sein de séances portant sur la résolution de problèmes – et partant la tâche donnée à l'élève – sont analysées via la gestion du temps et des interactions. Dans une perspective ergonomique (Leplat, 2000), nous mesurons enfin, à travers ces observations et des entretiens, l'écart entre tâche « prescrite » et tâche « effective ». Les premiers résultats nous ont permis de dégager une typologie déclinant trois profils dominants parmi les maîtres stagiaires. En outre, il semble que s'agissant de l'enseignement des mathématiques à l'école élémentaire, les stagiaires rencontrent certaines difficultés communes, caractéristiques des premiers pas dans le métier. Pour autant, l'opposition initiale entre pratiques des stagiaires et pratiques des maîtres expérimentés laisse place à un continuum intégrant la complexité des pratiques d'enseignement donnant lieu à de multiples déclinaisons. Au regard de l'analyse des résultats, la formation initiale des futurs professeurs des écoles pourrait être questionnée dans le but d'en améliorer la qualité via un processus réflexif. / The aim of our research is to try to identify the professional competences that have been acquired or are being acquired by new teachers during their training year (heuristic objective). To do so, we are following an ecological or complex paradigm (Clanet, 1997; Piot, 2014). We are particularly interested in the acquisition of competences related to three key notions such as time control, task, teacher-pupil interactions, that are studied by researchers integrated in the OPEN network (Observation des pratiques enseignantes). We presume that the professional development (Wittorski & Briquet-Duhazé, 2010), initiated at the beginning of a career, varies according to people and that this variability is interdependent of the level of these notions' competence mastering. The experience level is a major axis in our study; in a contrastive study, we shall oppose the trainee to the experienced teacher that are working in similar situations. If we aim to find out differences between professional trainees (Inter-trainee varaibility), we also claim to identify « invariabilities that show the presence of practice organisers » (Clanet, 2001). We try to identify typical beginner teacher organisers among teaching practice that are set up. To do so, we use mixed, quantitative (questionnaires) and qualitative (observation and interviews) methodologies. Questionnaires are about the mastering level of expected competences (Competence official list, 2013) and about the potential difficulties met by future teachers. People in the survey are trainees (N=178) as well as their temporary trainee supervisers (MAT: N=83). Eventually, the two representation studies are compared in order to assess their similarities. Six groups of three persons (a superviser and two trainees) in cycle 3 classes are being observed according to the three previously defined notions (Clanet, 2010). We focus on the notion of « task » in order to analyse the cross notions time and interactions. Common steps that are seen during lessons dealing with problem solving activities- and consequently tasks given to pupils- are analysed through time control and interactions. In an ergonomic perspective (Lepalt, 2000), we measure the gap between a « given » and an « effective » task through observation and interviews. The first results allow us to find out a typology of three main profiles among trainees. Moreover, in maths teaching at primary level, trainees meet similar obstacles that are common to beginners. The initial opposition between training and experienced teachers is replaced by a continuum which integrates complex teaching practice leading to multiple consequences. Through the result analysis, initial primary teacher training could be questioned in order to improve its quality, thanks to a reflexive process.

The focus of this study is on foundation phase and early childhood teachers’ professional identity formation. This study is about six beginning teachers in their first year of teaching early mathematics, science and technology (MST) in different schools and grade levels. Early childhood settings and primary schools in South Africa have a diverse learner body that increasingly demands of beginning early childhood and foundation phase teachers to continually strive to adapt their teaching and young children’s learning to the different learning environments for effective implementation of the curriculum. A learning identity framework was used to generate and analyse data. The learning identity framework is premised on the assumption that identity and learning are closely linked and that both are influenced by factors internal and external to the individual. Specifically, the study sought to answer the research question of how beginning first year early childhood and foundation phase teachers form, sustain or change their professional teacher identity in the teaching of mathematics, science and technology (MST) in the early years and in different school settings. The study used a phenomenological approach and case study method to explain the professional teacher identity formation process and to illuminate what factors influence this process. The study researched how teacher identities can be narratively constructed on the basis of the lived experiences of the six teachers in different school contexts. Data was generated from different sources for the purpose of triangulation which included visual and written narratives, observations and interviews (open and semi-structured). The analysis and results were based on categories of descriptions of themes. The findings indicate that identity formation is an ongoing process of integration of teachers’ personal and professional histories and initial teacher education and training, alongside issues of school culture and institutional (in-school) support. Those key factors emerge as strong determinants of the kinds and the relative stability or otherwise of professional identities which the six teachers develop in the first year of MST teaching, and thus the kind of reform minded teachers they become. / Thesis (PhD)--University of Pretoria, 2012. / Science, Mathematics and Technology Education / unrestricted
