[pt] A autorregulação da aprendizagem é o processo de monitoramento, controle e reflexão sobre o próprio aprendizado de acordo com o grau em que os estudantes atuam a nível cognitivo, motivacional e comportamental nesse contexto. Algumas pesquisas que investigam as estratégias observadas em alunos no contexto da aprendizagem demonstram que, ao invés de ajudá-los, possuem alto potencial prejudicador, as chamadas estratégias autoprejudiciais. Utilizando Jones e Berglas como principal referencial teórico deste construto, a presente pesquisa articula este construto com a atribuição de causalidade de Weiner, com o objetivo de fornecer arcabouço teórico para a investigação da adoção de estratégias autoprejudiciais de aprendizagem por alunos do 1º ano do ensino médio e a atribuição do desempenho escolar. Para isso, foram utilizados como instrumentos a Escala de Estratégias Autoprejudiciais para estudantes universitários, que foi adaptada para o ensino médio nesta pesquisa, e um protocolo de entrevista semiestruturada de autoria própria. Através dos escores totais observados na amostra (n=58), foram selecionados três estudantes que apresentaram os menores escores e três que apresentaram os maiores escores para participarem de entrevistas individuais, totalizando seis entrevistados. Os resultados quantitativos apontaram maior identificação dos alunos com estratégias autoprejudiciais como a preparação adequada antes de avaliações e o mau gerenciamento do tempo. Já os resultados qualitativos apontaram que, para o menor desempenho, foi possível observar que as atribuições de causalidade foram majoritariamente de lócus instável, não controlável e externo. E, para o maior desempenho, foi possível observar que as atribuições de causalidade foram majoritariamente de lócus interno, estável e controlável. Através das entrevistas, foram relatadas diferentes justificativas mobilizadas pelos estudantes para justificar o desempenho, como o estilo de aula dos professores, o estilo de aprendizagem, as características das disciplinas, a relação entre eles e os docentes, afinidade pela disciplina, a valorização da área do conhecimento pela família e o baixa capacidade de organização do estudo e gerenciamento do tempo. Dessa maneira, esta pesquisa pode contribuir para o entendimento das diferentes atribuições causais realizadas por alunos do ensino médio e para o olhar crítico sobre a relação entre a aprendizagem e outros fatores como cognição, metacognição, relações interpessoais e emoções. / [en] Self-regulation learning is the process of monitoring, controlling and reflecting on one s own learning according to the degree which students act at a cognitive, motivational and behavioral level in this context. Some research investigating the strategies observed in students in the context of learning has shown that, rather than helping them, they have a high potential for harm, the so-called self handicapping strategies. Using Jones and Berglas as the main theoretical reference for this construct, the present research articulates this construct with Weiner s attribution of causality, with the aim of providing a theoretical framework for investigating the adoption of self handicapping learning strategies by first-year high school students and the attribution of school performance. For that, the Self Handicapping Strategies Scale for university students, which was adapted for secondary school in this research, and a semi-structured interview protocol of my own authorship were used as instruments. Using the total scores observed in the sample (n=58), three students with the lowest scores and three with the highest scores were selected to take part in individual interviews, totaling six interviewees. The quantitative results showed that students identified more with self handicapping strategies such as inadequate preparation before assessments and poor time management. The qualitative results showed that, for the lowest performance, it was possible to observe that the causal attributions were mostly from an unstable, non-controllable and external locus. For the highest performers, the majority of causal attributions were internal, stable and controllable. Through the interviews, different justifications mobilized by the students to justify their performance were reported, such as the lecturing style of the teachers, the learning style, the characteristics of the subjects, the relationship between them and the teachers, affinity for the subject, the appreciation of the area of knowledge by the family and the low ability to organize study and manage time. In this way, this research can contribute to an understanding of different causal attributions made by high school students and to a critical look at the relationship between learning and other factors such as cognition, metacognition, interpersonal relationships and emotions.

[pt] A tese se propõe a discutir a emergência dos jovens de classes populares escolarizados na cena internacional e brasileira, assumindo que a questão juvenil foi amplamente transformada com a ampliação do acesso às escolas públicas de ensino médio, nos EUA e Europa a partir dos anos de 1950 e no Brasil a partir dos anos de 1990. Nesse sentido, nossa discussão pretende enfrentar o debate sobre como as novas juventudes populares e periféricas, e novos espaços de conflitos e de afirmação de direitos que são as escolas públicas ganham centralidade. Para tanto, nosso trabalho assume que, ao longo desse período, experimentamos um intenso debate sobre o lugar e o sentido da juventude na vida de um país que ainda experimenta um processo de democratização que também se materializa na própria democratização do acesso à fruição da juventude. A fim de explorar empiricamente essa questão elegemos quatro momentos como especialmente importantes que se deram entre os anos 2000 e 2017: as Conferências Nacionais da Juventude, as Jornadas de junho de 2013, o Movimento de Ocupação das Escolas, e o debate que deságua na Reforma do Ensino Médio e na Lei do Novo EM. Por outro lado, procuramos articular essa análise empírica com um debate teórico que pensa a questão juvenil e sua relação com a escola, bem como sua presença como protagonista de ativismos e movimentos sociais; e de outro lado, o debate sobre a escola de ensino médio como um local de disputas políticas. / [en] The thesis proposes to discuss the emergence of young people from popular classes educated on the international and Brazilian scene, assuming that the youth issue was largely transformed with the expansion of access to public high schools in the USA and Europe from the 1950 onwards. and in Brazil from the 1990s onwards. In this sense, our discussion aims to confront the debate on how new popular and peripheral youth, and new spaces of conflict and assertion of rights that are public schools, gain centrality. To this end, our work assumes that, throughout this period, we experienced an intense debate about the place and meaning of youth in the life of a country that is still experiencing a process of democratization that also materializes in the democratization of access to youth enjoyment.. In order to empirically explore this issue, we chose four moments as especially important that took place between the years 2000 and 2017: the National Youth Conferences, the June 2013 Days, the School Occupation Movement, and the debate that led to the Reform of Secondary Education and the New EM Law. On the other hand, we seek to articulate this empirical analysis with a theoretical debate that considers the youth issue and its relationship with school, as well as its presence as a protagonist of activism and social movements; and on the other hand, the debate about high school as a place for political disputes.

學科教學知識（PCK）是上世紀80年代提出的一種與教師課堂實踐緊密聯繫的知識。回顧學科教學知識的研究文獻發現，較少有研究專門針對學科教學知識轉化為課堂教學行為的過程。本研究選取三位中學化學教師作為案例，詳細描述和分析了PCK如何向課堂教學進行轉化。根據PCK的兩大維度一是關於“教"，二是關於“內容"，研究選擇了某一特定教學主題（化學反應速率）以及探究式教學來具體化這兩大維度。這樣研究就是從具有特定教學主題和教學取向的角度去闡釋PCK的轉化過程。轉化研究從四個方面進行展開：一是教師對於探究的知識和信念，二是以探究為教學取向的PCK，三是教師的課堂實踐行為，四是PCK與教學行為之間的聯繫和差異，以及影響PCK向課堂實踐轉化的因素。 / 研究發現PCK向課堂實踐的轉化，可以從三個方面進行闡釋。首先從教師所理解的探究知識而言，教師對探究的理解程度會影響教學目標的制定、教學內容的選擇、教學策略和教學評價的實施以及學生知識這些PCK的主要成分，繼而影響探究教學的實施。教師對探究的理解最主要的困難體現在三個方面：一是缺乏使用證據進行解釋的意識；二是將探究等同於“預測"、“實驗室活動"；三是重視“做"科學多於“說"科學，學生較少獲得交流與解釋的機會。 / 其次PCK本身的程度影響課堂教學實踐的轉化。研究發現三位教師當中，有經驗教師的PCK各個知識成分比較均衡，知識成分之間能夠產生聯繫，PCK與教學行為之間的差異較小。新手教師的PCK發展處於不均衡狀態，其中教學目標和評價知識較為豐富，但是缺乏充分的教學策略知識來實現教學目標的轉變。PCK不僅僅是知識成分的綜合，它體現了教師將不同知識整合的能力，有經驗教師的整合能力明顯高於新手教師。此外，學生知識是變化最為劇烈的PCK知識成分，教師需要特別的提示或是刺激才能促進其在教學計劃中更多地考慮學生。 / 最後，教師面對探究教學的實施總體呈現一種複雜而矛盾的信念。這背後的影響因素主要來自五個方面：一是教學觀念，例如教師對學習“過程"和“結果"的價值判斷，通常“結果"定律影響探究教學的實施；二是自我效能感，自我效能感高的教師更能實現教學轉化；三是學生觀念，教師對學生的評價越是負面，越會阻礙教學轉化；四是同伴學習，擁有同儕支持的教師能夠獲得更多的教學資源以及自我效能感，如果有優秀教師的引領，這種自我效能感將更加得到強化；五是教科書、課程標準、考試等外在因素，通常“課程"和“考試"是教師認為最容易阻礙探究教學實施的兩大外部壓力。 / 基於以上發現，研究建議值得繼續關注的問題是：進一步確定PCK的評級方法和工具，幫助教師形成均衡發展的PCK；促進教師深入理解和反思探究的本質；為教師提供支持性的環境，包括穩定的培訓環境、增加教師之間學習的機會、支持教師對自我教學進行不斷的改進和跟新、鼓勵教師形成積極、正面、陽關的教學心態。研究對於教師專業發展和提高科學本質觀的認識這兩方面具有一定的理論和實踐貢獻。 / The notion of pedagogical content knowledge (PCK) was proposed in the 1980s. PCK is closely related to teachers’ classroom practices, but a review of research on PCK revealed that few previous studies had focused on how PCK is transformed into classroom practice. Using three high school chemistry teachers in Beijing as cases, this study investigated the transformation process of PCK. They taught chemical reaction rate by using inquiry teaching and learning in their schools. Interviews and direct observations were used to collect data on the actual teaching and learning process in their classrooms. The research focused on four areas: teacher knowledge and beliefs about inquiry; the PCK for inquiry teaching; teacher behaviors in the classroom; and the transformation of PCK into classroom teaching as well as the factors affecting the transformation process. / It was found that the process of PCK transformation can be analyzed from three perspectives. First, teachers’ levels of understanding of inquiry affected their selection of learning objectives, content, teaching strategies, and assessment. Three major difficulties encountered by the three teachers were identified. Secondly, teachers’ levels of PCK influenced the transformation of PCK into classroom teaching. Experienced teachers were able to transform their PCK more easily than novice teachers. However, both experienced and novice teachers had to pay more attention to students’ needs when designing and implementing inquiry teaching. Thirdly, the three teachers held complex and conflicting beliefs about teaching and learning. The key factors affecting the transformation of PCK into classroom teaching included teacher self-efficacy, beliefs about student ability, peer support, textbooks, curriculum guides, and examinations. / These findings have important implications for teacher professional development and science teaching and learning in school. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / 廖梁. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2012. / Includes bibliographical references (leaves 331-350). / Electronic reproduction.

The researcher has observed and noted that out of the four regions of Swaziland, Shiselweni is the leading region with high schools that manifest a poor culture of learning and teaching. The summary of 2009 Junior Certificate results revealed that it is not only that Shiselweni had the lowest pass rate, but also that it recorded the highest number of failures when compared with the other three regions. The purpose of the study was to determine strategies that could be used by principals in promoting a culture of learning and teaching in Shiselweni high schools in Swaziland. The study pursued a qualitative research design which was explorative and descriptive. Qualitative methods were used to collect data from the respondents. Data was collected by means of focus group interviews with learners and teachers, and then through one-onone interviews with principals and parents. The sample was drawn from six high schools in the Shiselweni region that differed in their academic performance. Purposive sampling was used when selecting the schools and those who were to participate in the study. Data was constantly compared and analyzed using the coding method. Participants signed letters of consent and they were assured of the anonymity and confidentiality of the study. They were also made aware that they were not forced to participate in the study and that they were free to withdraw if they were so persuaded. Triangulation and the Guba’s trustworthiness model were used to enhance the reliability and validity of the study. Findings helped the researcher to arrive at recommendations on the role that principals should play in promoting a culture of learning and teaching in Shiselweni high schools in Swaziland. / Educational Studies / M.

Thesis (PhD)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: In this dissertation I report on an action research study in relation to the democratisation of science education in a Grade 10 life sciences classroom at a local high school through the application of educational technology, more specifically social network media such as Facebook. I argue that action research for social justice with the support of educational technology can contribute towards cultivating critical teaching and learning in the science classroom, thus contributing to the democratisation of science education in schools. In the main, this study shows that educational technology can contribute to the democratisation of science education in classrooms in relation to teaching contentious issues in the current life sciences school curriculum on three levels: firstly, learners and educators can experience enhanced levels of participation, collaboration and deliberation through Facebook; secondly, learners can construct personal learning contexts as a testament to the sense of autonomy they have (and can acquire) in learning about life sciences, particularly as they endeavour to nurture their critical and problem-solving skills, construct and apply life sciences knowledge, and integrate understandings of life sciences into the context of societal change; and thirdly, learners and educators can cultivate equal partnerships in the sense that equality refers to their insistence to „rupture‟ and „disrupt‟ pedagogical activities in the life sciences classroom. Finally, this study also reveals that critical teaching and learning in the life sciences classroom cannot be oblivious to poststructuralist thought on learning to think and act rhizomatically as opposed to hierarchically and linearly, and that exercising one‟s individual autonomy through a claim to intellectual equality can simply be pedagogical ingredients that can further enhance democratic science education in schools. / AFRIKAANSE OPSOMMING: In hierdie proefskrif doen ek verslag oor ‟n aksienavorsingstudie in verband met die demokratisering van wetenskaponderwys in ‟n Graad 10 lewenswetenskappe- klaskamer in ‟n plaaslike skool deur die toepassing van onderwystegnologie, meer spesifiek sosiale netwerkmedia soos Facebook. Ek argumenteer dat aksienavorsing vir sosiale geregtigheid met die ondersteuning van onderwystegnologie kan bydra tot die kultivering van kritiese onderrig en leer in die wetenskapklaskamer, wat dus bydra tot die demokratisering van wetenskaponderwys in skole. Hierdie studie bewys hoofsaaklik dat onderwystegnologie op drie vlakke kan bydra tot die demokratisering van wetenskaponderwys in klaskamers met verwysing na omstrede vraagstukke in die huidige lewenswetenskappe-skoolkurrikulum: eerstens kan leerders en opvoeders hoë vlakke van deelname, samewerking en beraadslaging deur Facebook ervaar; tweedens kan leerders persoonlike leerkontekste konstrueer as bevestiging van hulle sin van outonomiteit wat hulle bekom (en kan aanleer) deur leer oor die lewenswetenskappe, veral soos hulle poog om kritiese en probleemoplossingsvaardighede uit te bou, wetenskapskennis te konstrueer en toe te pas, en betekenisse van lewenswetenskappe in die konteks van sosiale verandering kan integreer; en derdens kan leerders en opvoeders gelyke verhoudings kweek in soverre gelykheid verwys na hulle aandrang daarop om pedagogiese aktiwiteite in die lewenswetenskappe-klaskamer te „verbreek‟ en te „ontwrig‟. Ten slotte wys hierdie studie dat kritiese onderrig en leer in die lewenswetenskappe-klaskamer nie onbewus kan wees van poststrukturalistiese denke oor die aanleer van risomatiese eerder as hiërargiese en liniêre denke en optrede nie, en dat die uitleef van individuele outonomie deur aanspraak te maak op intellektuele gelykheid die pedagogiese inspuiting kan wees wat benodig word om demokratiese wetenskaponderwys verder in skole te bevorder.

Cette étude cherche à identifier les types de comportements d’indiscipline qui ont des relations significatives avec les composantes de l'épuisement professionnel et à déterminer le rôle du sentiment d'autoefficacité des enseignants dans la relation entre l'indiscipline scolaire et l'épuisement professionnel. Nous avons fait parvenir des questionnaires, en début et fin d'année scolaire, à des enseignants d'écoles secondaires publiques francophones de la région de Lanaudière et de Québec. Nous avons procédé à des analyses statistiques longitudinales. Les résultats des régressions multiples (n=98) montrent que les actes d'hostilité à l'endroit des enseignants et la non-préparation des élèves sont associés positivement à l'épuisement professionnel et qu'un haut niveau du sentiment d'autoefficacité joue un rôle modérateur en regard des retards injustifiés de élèves et des actes d'hostilité. Les résultats des analyses qualitatives (n=449) confirment que la gestion de l'indiscipline est l'aspect le plus anxiogène de la profession enseignante et que, plus particulièrement, les actes d'hostilité des élèves à l'endroit des enseignants représentent les événements les plus stressants. La principale contribution de cette recherche se situe au niveau de la compréhension du rôle du sentiment d'autoefficacité des enseignants: un sentiment d'autoefficacité élevé représente un facteur de protection dans la relation entre l'indiscipline scolaire et l'épuisement professionnel. / The aim of this study was to identify misbehaviours that have significant relationships with professional burnout, as well as to determine the moderating role of teachers’ self-efficacy in these relationships. A self-reported questionnaire was administered at the beginning and at the end of the school year to 98 teachers from fifteen francophone public secondary schools of the region of Montréal (Canada). The results of multiple regressions indicated that acts of hostility directed towards teachers, and unpreparedness of students are positively associated with professional burnout, and that these two misbehaviours were less related to professional burnout when teachers reported a high level of self-efficacy The results of the qualitative analysis obtained with the help of QDA-Miner confirmed that the management of indiscipline is the most anxiety provoking aspect of the teaching profession, and that acts of hostility by students towards teachers are particularly stressful. The present study enhances our comprehension of the role of teachers’ self-efficacy: a high level of self-efficacy represents a factor of protection in the relationships between students’ indiscipline and professional burnout. Future research could deepen understanding of the impact of violent acts suffered by teachers on their professional fatigue, and of the role played by self-efficacy as a factor of protection.

[pt] O objetivo deste estudo é investigar a construção do posicionamento autoral em textos dissertativo-argumentativos produzidos por alunos do Ensino Médio, reconhecendo esta prática discursiva como espaço sociossemiótico de elaboração de estratégias argumentativas e negociação de significados. Considerando a escrita como atividade consciente, planejada, pensada e repensada, a presente pesquisa tem como suporte teórico: a perspectiva de linguagem proposta pela Linguística Sistêmico-Funcional (Halliday e Hassan, 1989; Halliday e Matthiessen, 1999; Eggins, 2004; Gouveia, 2009); o Sistema da Avaliatividade (Martin e White, 2005; Vian Jr, 2002); o estudo de Gêneros (Martin, 1992; Bakhtin, 1992; Miller, 1994) e teorias de Argumentação (Breton, 1999; Abreu, 2003). Textos dissertativo-argumentativos elaborados por alunos do terceiro ano do Ensino Médio, que simulam redações propostas em exames de vestibular, foram selecionados para a investigação da construção do posicionamento do autor. Os resultados indicam que recursos da Avaliatividade operam como potencializadores da construção do posicionamento do autor, atuando como possíveis estratégias argumentativas. Como contribuição teórica, a análise dos dados sugere uma estreita relação entre o potencial de significados da linguagem e o potencial argumentativo de um texto, realizada através de escolhas semânticas e lexicais aliadas a estratégias argumentativas, que resultam em potenciais de significados argumentativos. Logo, de acordo com este estudo, é possível tecer um paralelo entre a abordagem de linguagem proposta pela Linguística Sistêmico-Funcional e o estudo da argumentação. Implicações do estudo apontam para a latente necessidade de fazermos uso da abordagem Sistêmico-Funcional e da Avaliatividade em sala de aula, no ensino-aprendizagem de Língua Portuguesa, principalmente no que se refere à Produção Textual. / [en] The purpose of this study is to investigate the construction of authorial positioning in written argumentative texts produced by 12th grade students, regarding this discursive practice as a social semiotic space for creating strategies of argumentation and meaning negotiation. Considering writing as a conscious, planned and carefully thought activity, this research is theoretically supported by: the language perspective proposed by Systemic Functional-Linguistics (Halliday e Hassan, 1989; Halliday e Matthiessen, 1999; Eggins, 2004; Gouveia, 2009); the Appraisal System (Martin e White, 2005; Vian Jr, 2002); Genres Studies (Martin, 1992; Bakhtin, 1992; Miller, 1994) and theories of Argumentation (Breton, 1999; Abreu, 2003). Argumentative texts written by 12th grade students, which simulate compositions proposed in university entrance exams, were selected in order to investigate the construction of authorial positioning. Results indicate that Appraisal resources enhance the argumentative potential in the construction of authorial positioning, acting as possible strategies in the argumentation process. Considering the theoretical contribution, data analysis suggests a close relationship between language meaning potential and text argumentative potential, which are realized through semantic and lexical choices and are related to strategies of argumentation that result in argumentative meaning potentials. Therefore, according to this study, it is possible to create a parallel between the language perspective proposed by Systemic Functional-Linguistics and studies of argumentation. Implications of the study point to the latent necessity of using the Systemic-Functional and Appraisal frameworks in the classroom, in the teaching-learning of Portuguese Language, mainly in relation to the Written Production.

[pt] Esta tese de doutorado tem como objeto de estudo o exercício da docência na escola de ensino médio regular que atende setores populares, procurando identificar as especificidades que direcionam o fazer docente e as suas concepções sobre a própria profissão e este segmento de ensino. A pesquisa se desenvolve em uma escola pública de ensino médio localizada na Baixada Fluminense e considerada de prestígio na região. Metodologicamente, são observadas as práticas pedagógicas de um grupo de professores indicados pelos seus próprios alunos como bons professores, buscando identificar as características de seu desempenho e as competências que favorecem a aprendizagem dos jovens de classes populares. Além disso, utiliza-se de questionários aplicados aos alunos e professores, entrevistas com os docentes indicados, gestores e coordenadores pedagógicos. O contexto do trabalho docente na escola pesquisada é construído a partir do levantamento do perfil socioeconômico da região e dos alunos, da caracterização da rede de ensino e de dados sobre desempenho dos alunos via avaliações externas. As análises e interpretações foram construídas com base na interlocução teórica com os estudos sociológicos de Dubet, os estudos sobre formação e profissão docente de Formosinho, Tardif, Nóvoa, os estudos de Didática de Candau e sobre competência para ensinar de Perrenoud. Associam-se os dados quantitativos e os indicadores de desempenho docente produzidos pelas pesquisas de larga escala sobre eficácia escolar e efeito-professor (BROOKE e SOARES; BRESSOUX; OCDE; BANCO MUNDIAL). Ao longo da investigação, pôde-se constatar que há docentes desempenhando práticas bem sucedidas nas escolas de ensino médio e sendo reconhecidos pela instituição na qual trabalham e, principalmente, por seus alunos, como professores que fazem a diferença. As dimensões motivacionais e relacionais destacaram-se como os elementos norteadores da ação docente bem sucedida no ensino médio, centralizando o papel dos professores como construtores do sentido e profissionais da relação. São docentes que constroem suas próprias formas de lidar com a realidade da escola de ensino médio destinada as classes populares. Reforça-se a ideia de que o investimento em trabalho coletivo, prática reflexiva, coparticipação e envolvimento, associado a estratégias de acompanhamento do trabalho docente podem ser reconhecidos como estratégias para o desenvolvimento profissional dos professores e melhorias nos resultados dos alunos no ensino médio. Conclui-se que o alargamento das concepções do que constitui um bom professor de ensino médio podem contribuir tanto na instituição de políticas para fomentar o desenvolvimento da carreira docente, quanto dos próprios cursos de formação inicial e continuada dos professores especialistas. / [en] This doctoral thesis is teaching exercise the object of study in regular high school that serves popular sectors, seeking to identify the specifics that drive teaching and make their views on their profession and this educational segment. The research develops into a high school public school located in the Baixada Fluminense and considered prestigious in the region. Methodological, pedagogical practices of a group of teachers nominated by their own students as good teachers are observed in order to identify the characteristics of their performance and skills that foster the learning of popular class youth. In addition, it uses questionnaires given to students and teachers, interviews with the nominees teachers, managers and coordinators. context of teaching in the school investigated is constructed from the survey of socio-economic profile of the region and of the students, the characterization of the school system and performance data via the external evaluations students. Analyses and interpretations were based on theoretical dialogue with the sociological studies Dubet, studies on education and teaching profession of Formosinho, Tardif, Nóvoa, the Didactic studies on Candau and competence to teach Perrenoud. quantitative data and teacher performance indicators are associated produced by large-scale research on school effectiveness and effect-teacher (BROOKE and SOARES, BRESSOUX, OECD, WORLD BANK). Throughout the investigation, it could be seen that there are teachers performing successful practices in high schools and being recognized by the institution in which they work, and especially by his students as teachers that make a difference. The motivational and relational dimensions stood out as the guiding elements of successful teaching activity in high school, centralizing the role of teachers as builders direction and professional relationship. Are teachers who construct their own ways of dealing with the reality of high school designed the popular classes. The idea that investment is reinforced in collective work, reflective practice, joint participation and involvement, combined with follow-up strategies of teaching can be recognized as strategies for the professional development of teachers and improvements in student outcomes in high school. It is concluded that the extension of the conceptions of what constitutes a good teacher high school can contribute both in the establishment of policies to foster the development of the teaching career, as own initial training and continuing of specialist teachers.

The Framework for K-12 Science Education, the foundation for the Next Generation Science Standards, identifies scientific explanation as one of the eight practices "essential for learning science." In order to design professional development to help teachers implement these new standards, we need to assess students' current skill level in explanation construction, characterize current teacher practice surrounding it, and identify best practices for supporting students in explanation construction. This multiple-case study investigated teacher practice in eight high school science inquiry units in the Portland metro area and the scientific explanations the students produced in their work samples. Teacher Instructional Portfolios (TIPs) were analyzed with a TIP rubric based on best practices in teaching science inquiry and a qualitative coding scheme. Written scientific explanations were analyzed with an explanation rubric and qualitative codes. Relationships between instructional practices and explanation quality were examined. The study found that students struggle to produce high quality explanations. They have the most difficulty including adequate reasoning with science content. Also, teachers need to be familiar with the components of explanation and use a variety of pedagogical techniques to support students' explanation construction. Finally, the topic of the science inquiry activity should be strongly connected to the content in the unit, and students need a firm grasp of the scientific theory or model on which their research questions are based to adequately explain their inquiry results.
