The main objective of this research is to understand how the participants perceive themselves and the possibilities they have for the future with regard to the senses they give to teacher education and language teaching profession, since they are pre-service teachers. For this, we intended to identify and analyze emotions and cognitions related to becoming or not Portuguese and/or English language teachers, from the participants’ experiences reported in narratives. By having adopted a qualitative approach to collect and to analyze the data, this case study was conducted in a group of sixteen students who were majoring in English and Portuguese at a public university in the state of Goiás. The data were obtained through the school year of 2012 by means of questionnaires, life histories, collaborative discussion sessions, stimulated recall on audio recording, virtual journals, explanations of visual narratives and semi-structured interviews and were analyzed in the light of studies on the socio-historical-cultural theory and its theoretical developments and on Critical Applied Linguistics. The results suggest that teacher professional identities are complex phenomena, characterized by language and dynamic movements of construction, reconstruction and deconstruction of ways of being or not being a teacher, interrelated to the experiences narrated by the participants. Furthermore, we found that, within the unstable and contradictory processes of construction of professional identities, cognitions and emotions of participants, based on personal and social experiences of individuals with pre-service teacher education and language teaching professional, operate as significant elements for their identification or lack of identification with that profession. In this context, a number of factors nurture social and discursive positioning of the participants’ professional identities, which are not consistent for several reasons, including, for example, uncertainty about teaching profession due to financial dissatisfaction and current devaluation of teaching, as well as the lack of conditions for admission to other higher education courses. / Este estudo tem como foco a construção de identidades profissionais na formação inicial de professores de línguas. O objetivo principal desta pesquisa é investigar a maneira como os participantes compreendem a si mesmos e as possibilidades que têm para o futuro no que se refere aos sentidos conferidos à formação inicial e à profissão docente, uma vez que estão prestes a finalizar um curso de licenciatura. Para isso, buscou-se identificar e analisar cognições e emoções relacionadas ao tornar-se ou não professor de Português e/ou de Inglês, a partir das experiências relatadas em forma de narrativas. Adotando uma abordagem qualitativa de coleta e de análise dos dados, este estudo de caso foi conduzido em uma universidade pública do interior do estado de Goiás, e contou com a participação de dezesseis estudantes pertencentes ao último ano de Letras. Os dados, obtidos no ano letivo de 2012 por intermédio da utilização de questionários, histórias de vida, sessões colaborativas e de rememoração de aulas, gravadas em áudio, diários virtuais, explicações de narrativas visuais e entrevistas semiestruturadas, foram analisados à luz de estudos sobre a teoria sócio-históricocultural e seus desdobramentos teóricos e sobre a Linguística Aplicada Crítica. Os resultados apontam para o fato de que as identidades profissionais docentes são fenômenos complexos, caracterizados pela linguagem e por movimentos dinâmicos de construção, de reconstrução e de desconstrução de maneiras de ser ou não ser professor, intrincados às experiências narradas pelos participantes. Além disso, foi possível constatar que, nos processos instáveis e contraditórios de construção das identidades profissionais, as cognições e as emoções dos participantes, baseadas nas experiências pessoais e sociais desses indivíduos com a formação inicial e com docência, operam como elementos significativos para suas identificações ou não identificações com a profissão. Nesse bojo, uma série de fatores nutre o posicionamento social e discursivo das identidades profissionais dos participantes, as quais não se constituem sólidas por diversos motivos, entre os quais, por exemplo, estão a incerteza sobre a docência devido à insatisfação financeira e à desvalorização atual da carreira, bem como a falta de condições de ingresso em outros cursos de ensino superior almejados.

A teacher's disposition is a valued factor in special education; however, preservice teacher training in California higher education institutions does not require a focus on dispositions. The purpose of this quantitative correlational study was to examine whether common dispositions were associated with retention among teachers with comparable experience and preparation in special education. The study was grounded in constructivist learning theories including experiential learning, transformational learning, reflective practice, communities of practice, and situated learning. Data collection included responses to the Teacher Dispositions Index survey from 28 teachers in the partner school district. Results of multiple regression analyses indicated that effective communication and commitment to ethical professional behavior were common dispositions among persistent special education teachers. This research study affirmed special education teacher dispositions are difficult to define and assess. Future research is recommended regarding the dispositions of effective communication, commitment to ethical professional behavior, and supplemental dispositions present in the teaching profession. The doctoral project included a professional development seminar to foster persistence among special education teachers. Results may be used to increase percentages of persistent teachers in special education programs.

Abstract In this thesis, I will focus on the changes in the professional identity of pre-service teachers in mathematics, physics and chemistry during their teacher training. The study material consists of 43 pre-service teachers’ learning journals in the academic year of 2005–2006. Bruner (1986) separates two modes of thinking: Narrative and paradigmatic. In this study, I focus on narrative thinking. According to Denzin (1989), a story includes a plot, a middle point and an ending, and the turning points in the story often have a special meaning. In applying narrative method, and by using purposeful sampling I selected six different pre-service teachers’ journals as study material. Applying Polkinghorne’s (1995) approach, the pre-service teachers’ case descriptions were emplotted. The narratives included the changes that had happened in various subdomains of teacher’s professional identity. After that I compared the six case descriptions systematically on the basis of the central themes including the pre-service teachers’ self-esteem related to teaching and mastering the subjects, reflection, emotions, and how to deal with them, and beliefs of students and teaching. A special attention was paid to the changes in them. One point of interest was to find out what kind of meaning the teacher trainers had on the changes in the pre-sevice teachers’ professional identity. According to the main findings, only one pre-service teacher’s professional identity has developed during the training periods in all central aspects. Self-esteem related to mastering the subjects remained good with almost all the pre-service teachers, but self-esteem related to teaching improved with three cases, and got worse with two cases. With some pre-service teachers, the focus on their reflection changed from themselves towards student’s activity. Coping with tenseness, failures in dealing with negative emotions and insecurity about one’s professional identity were in the main role in their stories. All pre-service teachers had teacher-centered lessons in mathematics, but some started to value student-centered orientation also. Physics and chemistry lessons were more student-centered including, for example, project and lab work. Beliefs about students became more positive. The significance of the teacher trainers in developing a pre-servive teacher’s professional identity was often quite minor. / Tiivistelmä Tutkin matematiikan, fysiikan ja kemian aineenopettajaopiskelijoiden ammatti-identiteetin kehittymistä heidän opetusharjoittelunsa aikana. Tutkimusaineistona olivat 43:n lukuvuonna 2005–2006 opetusharjoitteluihin osallistuneiden opettajaopiskelijan pitämät oppimispäiväkirjat. Bruner (1986) erottaa kaksi ajattelun muotoa: narratiivisen ja paradigmaattisen. Tässä tutkimuksessa fokusoidun narratiiviseen ajatteluun. Denzinin (1989) mukaan tarinassa on juoni, alku, keskikohta ja loppu, ja käännekohdat tarinassa saavat erityisen merkityksen. Narratiivista lähestymistapaa käyttäen valitsin tutkimusaineistoksi harkinnanvaraisesti kuuden erilaisen opettajaopiskelijan oppimispäiväkirjat. Polkinghornea (1995) soveltaen juonensin opettajaopiskelijoiden tapauskuvaukset niin, että ne sisälsivät opettajan ammatti-identiteetin eri osa-alueissa tapahtuneet muutokset. Sen jälkeen vertailin tapauskuvauksia systemaattisesti keskeisten teemojen osalta. Keskeisiä teemoja olivat opettamiseen ja opetettavan aineen osaamiseen liittyvä itsetunto, reflektointi, tunteet ja niiden käsittely sekä uskomukset oppilaista ja opettamisesta. Kiinnitin erityisesti huomiota muutoksiin. Tarkastelin myös opetusharjoittelun ohjaajien merkitystä opettajaopiskelijan ammatti-identiteetin muutoksiin. Päätulokseni ovat seuraavat: Vain yhden opettajaopiskelijan ammatti-identiteetti kehittyi opetusharjoittelun aikana jokaisella opettajan ammatti-identiteetin keskeisellä osa-alueella. Opetettavan aineen osaamiseen liittyvä itsetunto säilyi lähes kaikilla opettajaopiskelijoilla hyvänä, mutta opettamiseen liittyvä itsetunto nousi kolmella ja laski kahdella opetusharjoittelun aikana. Opettajaopiskelijoiden reflektointi muuttui osalla itsestä oppilaan toimintaan kohdistuvaksi. Jännittämisestä selviytyminen, negatiivisten tunteiden käsittelyn epäonnistuminen ja epävarmuus opettajan ammatti-identiteetistä olivat pääosassa opettajaopiskelijoiden kertomuksissa. Opettajakeskeisyys painottui kaikilla opettajaopiskelijoilla matematiikan opetuksessa, osalla tapahtui muutosta oppilaskeskeiseen suuntaan. Fysiikan ja kemian oppitunneilla oppilaskeskeisyys näkyi oppilastöiden ohjaamisen kautta. Uskomukset yläasteen oppilaista muuttuivat positiivisemmiksi. Ohjaajan merkitys opettajaopiskelijan ammatti-identiteetin kehityksessä tuli melko vähän esille.

Since English has risen as the dominant language in the world, the demand for English language teachers has grown rapidly especially in the last three decades. Hence, English language teacher education has become an important concern in the Turkish national education system, which has forced the governments to implement a series of reforms. One of these was the Foreign Language Education (FLE) curriculum designed by the Higher Education Council (HEC), forwarded to all FLE departments in Turkish universities to be carried out starting from 1998-99. This curriculum was also used for pre-service English language teacher education in the Department of Foreign Language Education at Middle East Technical University (METU). However, a large scale evaluation study was not conducted on the effectiveness of the program or the competence of its graduates. This study primarily aimed at reaching the FLE graduates from 2002 to 2006 to investigate to what extent they perceive themselves competent as EFL teachers and to what extent they find the FLE program components successful in helping them gain these competencies. Besides, it also intended to reach the employers of FLE graduates to explore how competent these graduates are viewed and how successful METU FLE program is considered in serving its graduates gain teacher competencies. For this aim quantitative and qualitative data were collected through two graduate questionnaires, and graduate and elite employer interviews. The findings of the first graduate questionnaire revealed that the FLE graduates perceived themselves competent in most of HEC&rsquo / s competence areas, while the open-ended questionnaire items and interview data demonstrated a need for improvement for competencies of language knowledge, spoken use of English, classroom management, assessment and instruction. It was also seen in these two types of data that graduates&rsquo / perception of their strengths and weaknesses in HEC&rsquo / s foreign language teacher competencies and their need for developing other competencies depend on the level they teach, the type of school they work at and the length of experience they have. Similarly, some of the employers, according to the institution where they have elite positions, indicated a high level of satisfaction with the FLE graduates&rsquo / competence in language and subject knowledge, inclass and out-of class competencies, while some of them emphasized a need for improvement in competencies of language knowledge and use, and putting theory into practice. In addition, although the program was reported to have a strong and positive role on the development of professional competencies in the teacher candidates, it was also stated that the five components and some courses of the program need revisions in terms of their content, methodology of instruction and assessment. Moreover, the need for communication among the components of the program was also expressed, as the graduates mention unnecessary overlaps among some courses. In the light of these findings, some suggestions are made towards program improvement.

The special learning needs in Initial Teacher Education of international postgraduate students whose own education was linguistically and culturally different to that of New Zealand students are often unacknowledged and under-researched. This qualitative study, based on narrative inquiry, presents case studies of six participants from six different countries, languages and cultures. The findings point to challenges faced by pre-service teacher education students from other languages and cultures. Tensions created by language difficulties, new pedagogies and social and educational cultural differences lead to feelings, at times, of disorientation, heightened “otherness” and unease. Students who are crossing the border between one culture and pedagogical belief system to another require specific support. This study did, however, find evidence of students developing new understandings about teaching and learning. The findings carry implications for the content, delivery and pedagogy of Initial Teacher Education programmes. The introduction of a Foundation Course and a Support Group, modelling of good practice by ITE lecturers using a variety of interactive teaching strategies and targeted reflective practices are suggested. In a time of teacher shortages, changing demographics in schools and the changing nature of university-based ITE it is important that the assumption that one size fits all in ITE all needs to be put aside. From the perspectives of social justice and acceptance of diversity it is timely to pay attention in ITE to the learning of students from other languages and cultures. This study suggests ways of moving towards this goal.

This study was conducted to investigate the change in pre-service teacher education in Turkey by using Chaos Theory. The research questions were the following: 1) How did the 1982 restructuring relate to the 1998 restructuring? (2) What were the reasons for the anomalies that led to the 1998 restructuring? (3) How did the 1998 process of transformation work? (4) At which stage of the curve is the system now? (5) What are the possible paths the new model may evolve? The data sources in this qualitative research study were interviews and documents. The 28 participants of the interviews included some key decision-makers at related institutes and some academic staff at 8 different Education Faculties in Ankara, EskiSehir, Bolu, Adana, and KirSehir. The written documents included some relevant reports, meeting minutes, the proceedings of conferences and panel discussions, research articles, and some articles of four different newspapers in Turkey. A model of &lsquo / Change as Chaotic Transformation&rsquo / was designed by the researcher as a theoretical framework. The data, subjected to a content analysis, revealed that the logic of chaotic transformation has significant implications in investigating and understanding the stability versus instability phases in teacher education affairs in Turkey / roughly 1950s - 1970 (evolution and stability), 1970s (disequilibrium and turbulence), 1982 &ndash / early 1990s (&lsquo / forced stability&rsquo / ), and mid-1990s to 1998 (turbulence and transformation) are significant phases in this sense. The data also revealed that the reasons for the anomalies that led to the 1998 restructuring were in both program and administrative issues. Further, the process of transformation in 1998 was &lsquo / self-organization.&rsquo / It is found that presently the 1998 model is perceived as not yet institutionalized / the achievements in program issues realigned teacher education to its &lsquo / identity&rsquo / , but the path the new model may evolve depends on the clarification and institutionalization of &lsquo / governance&rsquo / and implementing strategies for developing &lsquo / human resources&rsquo / (the teacher educator profile).

Orientador: Prof. Dr. Sérgio Henrique Bezerra de Sousa Leal / Dissertação (mestrado) - Universidade Federal do ABC, Programa De Pós-Graduação em Ensino, História, Filosofia das Ciências e Matemática, 2016. / Pesquisadores têm defendido a profissionalização da profissão docente, sendo a construção de um conhecimento base um dos passos necessários. Dentre estes pesquisadores destacamos Shulman, que propôs sete conhecimentos base para o professor, destacando, dentre eles, o Conhecimento Pedagógico do Conteúdo (PCK, da sigla em inglês), um conhecimento específico do professor. Nesta perspectiva da profissionalização, uma ação conjunta de órgãos brasileiros instituiu o Programa Institucional de Bolsa de Iniciação à Docência (Pibid), um programa voltado principalmente para os licenciandos, que tem como um dos principais objetivos a valorização da atividade docente. Este estudo teve como objetivo principal analisar as contribuições do Pibid da Universidade Federal do ABC (UFABC), subprojeto Química, para o estímulo, mobilização e/ou manifestação da base de conhecimentos para a docência de graduandos da UFABC. Durante o tempo que o subprojeto foi acompanhado, duas atividades foram desenvolvidas: atividades lúdicas e unidades de medida. A primeira atividade tinha como objetivo a elaboração de uma atividade lúdica por parte dos bolsistas do Pibid, com uma posterior aplicação. A segunda atividade tinha como objetivo trabalhar as grandezas massa, comprimento e volume através de atividades elaboradas pelos bolsistas. Coletamos dados em ambas as atividades por meio de registros audiovisuais e relatos escritos e orais dos alunos. Os dados foram submetidos a uma análise categorial (Bardin, 2011), utilizando como categorias os domínios do conhecimento e manifestações do PCK propostos por Rollnick et al. (2008). Para o primeiro ciclo, nossos resultados mostram que alguns domínios de conhecimento foram estimulados e mobilizados, porém não foi suficiente para sobrepor as deficiências no conhecimento do tema, o que resultou em um PCK deficiente. No entanto, o segundo ciclo, além de focar somente em um tema (unidades de medida), também teve atividades de longo prazo, resultando em uma melhor amalgamação dos domínios de conhecimento e, consequentemente, um desenvolvimento no PCK. Concluímos, portanto, que o Pibid proporciona um ambiente favorável às reflexões e discussões acerca de temas relacionados à construção do conhecimento base para o ensino, seja desenvolvendo algum conhecimento de forma teórica, seja quando o aluno mobiliza o conhecimento para realizar determinada atividade. / Researchers have defended the professionalization of the teaching profession. Among these researchers highlight Shulman, who proposed seven knowledge base for teacher, highlighting, among them, the Pedagogical Content Knowledge (PCK). The PCK is a specific knowledge of the teacher. In professionalization perspective, a joint action of Brazilian agencies established the Institutional Program Initiation Grant to Teaching (Pibid, the initials from Portuguese), a program mainly aimed at undergraduates, which has as a major goal the enhancement of teaching activity. This study aimed to analyze the contributions of Pibid from Federal University of ABC, subproject Chemistry, for the stimulation, mobilization and/or manifestation of the students knowledge of the fields of UFABC. During the time that the subproject was accompanied, two activities were developed: ludic activities and measurement units. The first activity was aimed at the development of a ludic activity by students teachers, with a subsequent application. The second activity was designed to work the mass quantities, length and volume through activities developed by students teachers. We collect data in both activities through audiovisual records and oral and written reports of students. The data were submitted to a categorical analysis (Bardin, 2011), using as categories the domains and manifestations of PCK proposed by Rollnick et al. (2008). For the first cycle, our results show that some domains of knowledge were stimulated and mobilized, but was not enough to overcome the deficiencies in the subject matter knowledge, which resulted in poor PCK. However, the second cycle, and only focus on a subject matter (measurement units) also had long-term activity, resulting in better amalgamation of domain knowledge, and hence a development in PCK. Therefore, we conclude that the Pibid provides a favorable environment for reflections and discussions on topics related to building the knowledge base for teaching, or developing some knowledge of theoretical form, or is when the student mobilizes knowledge to perform some activity.

Orientadora: Profa. Dra. Thaís Cyrino de Mello Forato / Dissertação (mestrado) - Universidade Federal do ABC, Programa De Pós-Graduação em Ensino, História, Filosofia das Ciências e Matemática, 2016. / Um dos desafios de se utilizar História e Filosofia da Ciência (HFC) no ensino e aprendizagem de ciências pode estar relacionado à carência de ações mais efetivas na formação dos professores, que lhes forneça subsídios para o prosseguimento de atividades com essa temática (Höttecke & Silva 2011). Partindo desse pressuposto, esta pesquisa busca contribuir na preparação de futuros professores para inclusão da HFC em sua prática. Objetiva-se o desenvolvimento de sua autonomia frente as dificuldades encontradas tanto na localização, como nos usos de materiais com perspectiva historiográfica diacrônica e atual. A proposta didática construída visa mobilizar discussões que abordam aspectos científicos e metacientíficos por meio de um recorte histórico, elaborado a partir dos estudos do engenheiro e físico francês, Nicolas Léonard Sadi Carnot (1796-1832), publicados em 1824, no qual se discute sobre os possíveis melhoramentos em máquinas térmicas, com intuito de potencializar a produção de força motriz. A metodologia inclui a pesquisa bibliográfica de conteúdos da história das ciências e do ensino de ciências. Além de elementos que se fundamentam na pesquisa qualitativa como suporte para a imersão da pesquisadora no ambiente ao qual a proposta se destina. E o uso de parâmetros, propostos por Forato (2009), que nortearam a construção do recorte histórico, assim como, o desenvolvimento da proposta didática, considerando o contexto de formação inicial de professores. / One of the challenges of using History and Philosophy of Science (HPS) in teaching and learning science can be related to the lack of more effective actions in teacher education, to provide them subsidies to use these topics (Höttecke & Silva 2011). In this perspective, this research aims to contribute to the preparation of future teachers to use HPS in the classroom. This practice can contribute to developing teacher¿s autonomy by overcoming the difficulties presented in material, as in the use of material with diachronic and current historiographical perspective. The didactic proposal aims to mobilize discussions that address scientific and metascientific aspects through a historical approach, developed from the studies of Nicolas Léonard Sadi Carnot (1796- 1832) French engineer and physician, published in 1824, his work discussed possible improvements in thermal machines, aiming to enhance the production of motive power. The methodology includes a study of his bibliography from the history of science and science education. In addition, we use elements based on qualitative research as a support for the immersion of the researcher in the environment to which the proposal is intended. And the use of parameters proposed by Forato (2009), which guided the construction of the historical episode, as well as the development of the didactic proposal, considering the pre-service teacher training contexts.
