Relatório no âmbito da unidade curricular prática de ensino supervisionada, realizada na Escola Secundária/3 Rainha Santa Isabel de Estremoz

O presente relatório foi produzido no âmbito da unidade curricular Prática de Ensino Supervisionada, que faz parte do Mestrado em Ensino do Português no 3º Ciclo do Ensino Básico e Ensino Secundário e de Espanhol nos Ensinos Básico e Secundário, sob a orientação da Professora Doutora Ângela Maria Franco Martins Coelho de Paiva Balça. Identifica-se, na sua essência basilar, como um trabalho reflexivo-descritivo sobre a prática aplicada e efetuada no ano letivo 2015/2016, no lecionamento das disciplinas de Português em duas turmas de 10º ano, e de Espanhol – Língua Estrangeira I numa de 7º ano, na Escola Secundária/3 Rainha Santa Isabel, de Estremoz. Além do mais, também constitui o expoente de todo o processo levado a cabo durante os dois anos do Mestrado, o qual permitiu e conduziu à revisão, modificação, inovação e progressão em matéria de conceitos, ideias, noções, ações e teorias, quer fossem mais antigas ou recentes. Este é o produto final e contributo para o desenvolvimento e melhoria a nível pessoal e profissional. Através do conhecimento da literatura teórica e da sua aplicação na ação, a reflexão compromete-nos a cumprir uma prática fundamentada e apoiada em toda a documentação mundial, europeia e portuguesa normativa e de referência para o exercício da profissão docente o mais completo e eficaz possível. Mais do que um relatório, é uma avaliação orientativa da dimensão transformadora no desempenho docente que, na sua parte mais cogitativa, expõe estruturalmente: a observação e o seu registo; a observação em contexto; a planificação; a orientação; a componente letiva – aulas lecionadas (análise, aprendizagem e melhorias) e a pesquisa reflexiva na abordagem dos inquéritos passados nas turmas de Português e de Espanhol; e, por fim, a abordagem reflexiva sobre a avaliação formativa das aprendizagens realizada às turmas de 10º ano, na disciplina de Português; ABSTRACT: This report was produced in the scope of Supervised Teaching Practice’s curricular unit, which is part of the Master’s Degree in Teaching Portuguese for the 3rd stage of Primary Education and Secondary Education, and Spanish Foreign Language Teaching for Primary and Secondary Education, under the supervision of Dr. Ângela Maria Franco Martins Coelho de Paiva Balça. In its basic essence, this is a reflective and descriptive paper about practices applied and performed for the 2015-2016 school year to teach Portuguese, in two tenth grade classes, and Spanish as a Foreign Language, in one seventh grade class at Rainha Santa Isabel School of Estremoz. Furthermore, it outlines the entire process carried out during the two years of the Master’s Degree, which provided and led to review, change, breakthrough, and advancement regarding concepts, ideas, assumptions, and theories, whether they were pre-existing or more recent. This is the final product and the contribution towards development and improvement in personal and professional terms. Through knowledge of theoretical literature and applying it to practice, the reflection leads us to compile substantiated and supported practice in all worldwide, European, and Portuguese standards and reference documentation for the most effective pursuit of the profession. More than a report, this is an evaluation of transformation in teaching performance that structurally examines the following: observation and its registration; observation in the field; lesson design; guidance and monitoring; a teaching component (analysis, apprenticeships, and improvements) with a reflective element based on the results of the Portuguese and Spanish class surveys; and, finally, a reflexive approach about formative assessment of student learning that took place within the Portuguese course.

A avaliação da aprendizagem na escola Waldecy Corrêa: um estudo na terceira e quarta série do ensino fundamental I

O presente estudo, sobre avaliação de aprendizagens, apesar de ser abordado por outros autores de variadas formas, esboça-se aqui com o tema A Avaliação da Aprendizagem na Escola Waldecy Corrêa: um estudo na terceira e quarta série do ensino fundamental I que tem como finalidade uma análise teórica e prática acerca da avaliação no processo de ensino e aprendizagem na escola supracitada. Essa abordagem constitui-se de extrema relevância para o entendimento da temática, haja vista, que a avaliação da aprendizagem ser um assunto bastante discutido entre os teóricos que postularam um significado com o propósito de nortear a base conceituai sobre o tema em estudo. Para embasar teoricamente foram imprescindíveis as ideias produzidas por alguns autores como Luckesi, Hoffmann, Perrenoud, Sant’Anna, Saul, além das políticas públicas como a LDB\ PCN's2, a Sistemática de Avaliação do Estado do Amapá entre outros, que focalizam a importância desta temática. Embora a estimativa produzida na presente pesquisas se traduza em efeitos de mudança na forma de aplicar a avaliação da aprendizagem com a realidade analisada. Os procedimentos metodológicos envolveram tanto a técnica qualitativa - articulada com o estudo de caso envolvendo como instrumentos na coleta de dados as observações e entrevistas, bem como a quantitativa como tratamento das informações recolhidas pela aplicação dos questionários para obtenção de resultados em consonância com nossos objetivos. As informações obtidas por meio dos resultados revelaram tendencialmente que os investigados estão perpassando de uma concepção de avaliação seletiva para uma avaliação de processo, embora tenha se observado alguns contrapontos. Nesse sentido, a proposta é que o professor busque ampliar o seu entendimento acerca da avaliação para que possa promover uma nova cultura do verdadeiro sentido do que, como, quando e para que avaliar. Dessa forma, a avaliação da aprendizagem se manifestará objetivando uma ação reflexiva e emancipatória dos sujeitos envolvidos em sua processualização. ABSTRACT: ln spite of being approached in several ways by other authors, the present study here outlines itself with the theme "The Evaluation of the Learning at Waldecy Corrêa School: a study in the third and fourth year of the primary education" and its purpose is a theoretical and practical analysis about the evaluation in the process of teaching and learning at the aforesaid school. This approach is constituted of extreme relevance for the understanding of the thematic in as much as the evaluation is a subject discussed a lot among the theorists who postulate a meaning with the purpose of guiding conceptual basis on the theme studied. The ideas produced by some authors, such as Luckesi, Hoffmann, Perrenoud, Sant'Anna, Saul, besides the public politics like the LDB\ PCN's2, the systematic of evaluation of the State of Amapá, among others that focus on the importance of this thematic were indispensable to give it basis theoretically. Although the estimate produced in the present research is translated into effect of change in the way of applying the evaluation in the learning together with the reality analyzed. The methodological procedures have involved the qualitative technique - articulated with the study of cases having as the tools in the data collection the observations and interviews - as well as the quantitative technique as treatment of the information collected by applying the questionnaires for obtaining the outcomes in harmony with our goals. The information obtained by the results has revealed the tendency that the investigated students are changing from a conception of selective evaluation to an evaluation of process. Although we have observed some counterpoints. ln this sense, the proposal is that the teacher looks for enlarging his understanding about the evaluation so that he can promote a new culture of the true sense of "what", "how", "when" and ''what for" to evaluate. This way, the evaluation of learning will be made known by aiming at a reflexive and emancipating action of the subjects involved in their processing.

i-Cobb - An innovative technique in spinal radiographic measurement

The measurement of Cobb angles from radiographs is routine practice in spinal clinics. The technique relies on the use and availability of specialist equipment such as a goniometer, cobbometer or protractor. The aim of this study was to validate the use of i-Phone (Apple Inc) combined with Tilt Meter Pro software as compared to a protractor in the measurement of Cobb angles. Between November 2008 and December 2008 20 patients were selected at random from the Paediatric Spine Research Groups Database. A power calculation was performed which indicated if n=240 measurements the study had a 96% chance of detecting a 5 degree difference between groups. All patients had idiopathic scoliosis with a range of curve types and severities. The study found the i-Phone combined with Tilt Meter Pro software offers a faster alternative to the traditional method of Cobb angle measurement. The use of i-Phone offers a more convenient way of measuring Cobb angles in the outpatient setting. The intra-observer repeatability of the iPhone is equivalent to the protractor in the measurement of Cobb angles.

Low-complexity estimation of CFO and frequency independent I/Q mismatch for OFDM systems

CFO and I/Q mismatch could cause significant performance degradation to OFDM systems. Their estimation and compensation are generally difficult as they are entangled in the received signal. In this paper, we propose some low-complexity estimation and compensation schemes in the receiver, which are robust to various CFO and I/Q mismatch values although the performance is slightly degraded for very small CFO. These schemes consist of three steps: forming a cosine estimator free of I/Q mismatch interference, estimating I/Q mismatch using the estimated cosine value, and forming a sine estimator using samples after I/Q mismatch compensation. These estimators are based on the perception that an estimate of cosine serves much better as the basis for I/Q mismatch estimation than the estimate of CFO derived from the cosine function. Simulation results show that the proposed schemes can improve system performance significantly, and they are robust to CFO and I/Q mismatch.

"Well, now I'm upset": Moral and social orders in the playground

There is much still to learn about how young children’s membership with peers shapes their constructions of moral and social obligations within everyday activities in the school playground. This paper investigates how a small group of girls, aged four to six years, account for their everyday social interactions in the playground. They were video-recorded as they participated in a pretend game of school. Several days later, a video-recorded excerpt of the interaction was shown to them and invited to comment on what was happening in the video. This conversation was audio-recorded. Drawing on a conversation analysis approach, this chapter shows that, despite their discontent and complaining about playing the game of school, the girls’ actions showed their continued orientation to the particular codes of the game, of ‘no going away’ and ‘no telling’. By making relevant these codes, jointly constructed by the girls during the interview, they managed each other’s continued participation within two arenas of action: the pretend, as a player in a pretend game of school; and the real, as a classroom member of a peer group. Through inferences to explicit and implicit codes of conduct, moral obligations were invoked as the girls attempted to socially exclude or build alliances with others, and enforce their own social position. As well, a shared history that the girls re-constructed has moral implications for present and future relationships. The girls oriented to the history as an interactional resource for accounting for their actions in the pretend game. This paper uncovers how children both participate in, and shape, their everyday social worlds through talk and interaction and the consequences a taken-for-granted activity such as playing school has for their moral and social positions in the peer group.

Concurrent multi-scale modeling of civil infrastructures for analyses on structural deterioration—Part I : Modeling methodology and strategy

This paper aims to develop the methodology and strategy for concurrent finite element modeling of civil infrastructures at the different scale levels for the purposes of analyses of structural deteriorating. The modeling strategy and method were investigated to develop the concurrent multi-scale model of structural behavior (CMSM-of-SB) in which the global structural behavior and nonlinear damage features of local details in a large complicated structure could be concurrently analyzed in order to meet the needs of structural-state evaluation as well as structural deteriorating. In the proposed method, the “large-scale” modeling is adopted for the global structure with linear responses between stress and strain and the “small-scale” modeling is available for nonlinear damage analyses of the local welded details. A longitudinal truss in steel bridge decks was selected as a case to study how a CMSM-of-SB was developed. The reduced-scale specimen of the longitudinal truss was studied in the laboratory to measure its dynamic and static behavior in global truss and local welded details, while the multi-scale models using constraint equations and substructuring were developed for numerical simulation. The comparison of dynamic and static response between the calculated results by different models indicated that the proposed multi-scale model was found to be the most efficient and accurate. The verification of the model with results from the tested truss under the specific loading showed that, responses at the material scale in the vicinity of local details as well as structural global behaviors could be obtained and fit well with the measured results. The proposed concurrent multi-scale modeling strategy and implementation procedures were applied to Runyang cable-stayed bridge (RYCB) and the CMSM-of-SB of the bridge deck system was accordingly constructed as a practical application.

“I am a secondary teacher and I teach history and SOSE” : negotiating pre-service teacher identities in times of curriculum change

Secondary social education in Australia is set to change with the new national history curriculum but integrated social education will continue in the middle years of schooling. Competing discourses of disciplinary and integrated social education approaches create new challenges for pre-service teachers as identification with a teaching area is an important aspect of developing a broader teacher identity. Feedback on a compulsory, final year curriculum studies unit revealed the majority of secondary pre-service teachers identified with at least one social science discipline. However, only a small number listed the integrated social education curriculum of Studies of Society and Environment (SOSE), even though SOSE was an essential part of their brief. More complex identities were revealed in post-teaching practice interviews. In times of curriculum change, attention to pre-service teachers’ disciplinary knowledge is critical in developing a stable subject identity.
