Atividades investigativas: o impacto na capacidade de argumentação em alunos do ensino médio sobre eletroquímica

The education research guidelines have shown the important contribution of the investigations that focus on analysis of the discursive dimension of teaching and learning of Science in actual classroom. An interesting proposal to analyze the effectiveness of an educational activity is to assess the potential of investigative activities in the development of argumentation in science classes. Several studies have taken into account the use of argument in the classroom as a way to provide students with new ways to know the science. Argument refers to the process of associating components that play a central role in the construction of explanations, models and theories. In order to investigate the potential of these activities took place the application of investigative activities with third-year high school students, recorded in audio and video, focusing on the development of the argument. The search, conducted ranks as a qualitative research with characteristics of a case study. The arguments collected during the activities contained the students' conceptions about the concepts discussed and all were recorded in audio and video. With the encouragement of the argument by the investigative activity we evaluate the learning experienced by the speech of students. It may be noted that students have appropriated the concept of oxidation involving electron transfer, thus the activity reached the goal, so that was planned, making it effective for the introduction of electrochemical concepts

Os sentidos sobre o professor e sua formação em 15 anos de Zetetiké: 1993 - 2007

This research presents a study on mathematics teacher education, examining the bibliographic production in 15 years of the journal Zetetiké (1993-2007), totalizing 140 papers. From these, 49 were classified as ‘teacher formation’, thus constituting the corpus of the investigation. The research focused on three units of recording and analysis: (i) problems of research; (ii) the meanings of ‘being a teacher’ and their ‘duties’; and (iii) the meanings of ‘teacher’s education’. For the processes of categorization we use Textual Analysis, which allowed us to observe some trends. Regarding the problems of research we found that the research actions involve a range from: to report, disclose, describe, identify up to study, discuss, understand, evaluate. With reference to ‘being teacher’ and its ‘duties’ in the whole period of this study it were pointed problems related to the mathematical content and to the pedagogical project of the school unit, with 30 papers giving prescriptions for the teachers actions in its educational context. With regard to the meanings on teacher education, the most frequent references concern: the functions of teacher formation; what is expected of the teacher during and after the education processes; and the emphasis on the importance of initial formation for mathematics teacher’s education.

Uma descrição semiótica da metáfora no ensino de biologia: asserções sobre a célula animal

The main objective of this survey is describing signly the metaphor learning resource, with focus on biology education. Our teorical reference is the peircean semiotics, because it means solid heritage to code surveys implicated at science education, it led us to do an explanation about the main lines about that reference, addressed to researchers and lecturers interested in those reasonings. In the description yearned, another objectives appear: demonstrate diferences between metaphor/analogy and pragmatic analogy; to list metaphors, from cell representation analysis, and argue about principals diferences and probable cognitive consequences between the metaphor event in the visual representation and speech sentences. Therefore we analysed the animal cell of a high school first grade studying book – biology – cell biology – used by São Paulo and another state students. The findings demonstrate the undeniable importance of the metaphor as a learning tool in the biology education, and new findings about that, such as its limits in the concept elaboration, gnosiologic consequences for receptioning, the search needs for propositions– pictures between concept relations – in the science speech construction, and other results.

Mídia-educação no ensino médio: uma experiência com alunos e professores

This paper describes the development of educational materials on media education as a result of workshops held for students and teachers of high school in Midialab – Media Education Laboratory of Universidade Sagrado Coração. The objectives of this exploratory research were to investigate how teachers and students learn about media, looking for similarities and differences in the performance of the two groups in order to make it possible to conclude what methodology frameworks had a best result for promoting the media literacy of each group, taking on account the characteristics of public school and the paradigms of international media literacy. The methodology involved the application of activities focusing on six strategies: textual analysis, contextual analysis, content analysis, case study, translation, simulation and production. The results suggested that such activities are a productive way to develop critical reading skill and to reduce the differences between teachers and students’ repertoire. They also presented good results in the development of language usage by them and promoted collaborative learning, in a social approach.

Mulheres na politica e na mídia Brasileira: breve histórico e cenário atual

Brazil was one of the four countries of Latin America to be elected in this century, the first time a woman for president.

El intelectual, el desierto, el 'otro' : Un análisis de Viaje al País de los Araucanos de Estanislao Zeballos

En este trabajo me propongo abordar diversos tópicos presentes en la obra Viaje al país de los Araucanos de Estanislao Zeballos, en especial, los referidos a la figura del intelectual, la construcción discursiva y fáctica del Desierto, y la figura del otro, con sus diversas connotaciones devaluadoras. El enfoque teórico utilizado, a grandes rasgos será el la teoría del discurso social de Marc Angenot y el de la perspectiva de género. A partir de lo cual intentaré vislumbrar, en uno de los ejemplos por excelencia del discurso social que circuló en la época de consolidación y expansión del Estado Nacional argentino, ciertas categorías propias del pensamiento occidental. Entre ellas, tomaremos de manera general, las dicotomías excluyentes Cultura/Naturaleza, Razón/Emoción, Civilización/Barbarie, Modernidad /Prehistoria, Progreso/Atraso, Hombre/Mujer, Hombre/Animal. Estas categorías se hacen patentes, por ejemplo, en las descripciones de los indios como salvajes y por ello, violentos, impulsivos o pasionales, incapaces de adaptarse a la vida civilizada (a su racionalidad, institucionalidad, legalidad, moralidad, en fin, a una estructuración política, cultural, social y económica ajena); más aun, por estar más cerca de la naturaleza o lo silvestre (al obtener de allí casi todo lo necesario en una economía de subsistencia), son vistos como seres primitivos, y por ello devaluados, caracterizados de manera animal y/o femenina, para posteriormente ser instrumentalizados (desde la racionalidad del varón blanco) y tratados como objetos (como soldados o baqueanos obligados, cuando no, eliminados , o como mera pieza de museo)

Os discursos sobre a educomunicação na rádio escolar: um estudo etnográfico e m uma escola pública

This research analyzes the discursive construction of Educommunication, from a training course of educommunicators, with teachers and students of school Profº Francisco Ivo Cavalcanti, state public school, geographically located in the city of Natal / RN, studying the constitution of the meanings that educommunication practice in School Radio acquires for trainers and course participants (teachers and students). The socio-historical context in which this research is based corresponds to the new social reality, mediated by information and communication Technologies. These technologies drive the educational institution to train students in the use of different languages that permeate society. But to do so, you must have also enabled teachers to work Communication technology to meet the aspirations of young people and adults who are part of the educational community. The objectives are to identify the conditions of discursive production around the educommunication practice in Radio School, examine the discursive construction of instructors and course participants in Educommunication and its dialogical brands, and see how the course participants relate to their educommunicative practice in the educational contexts, attributing meaning to the place of teachers and students. Therefore, this research uses ethnography applied to the school context as a methodological option, Pecheuxtian Discourse Analysis, the principles of Educommunication, the reflections of Paulo Freire and the concepts of Dialogism in Bakhtin as theoretical contributions. We adopted three areas of knowledge: Language, Communication and Education, in order to produce an analysis committed to the aspects that involve the use of radio in the school environment to promote an educommunicative practice. With this research we have built a web of meanings about the school that we are forming or we want to form in the XXI century, because we used the discourses of teachers and students immersed in new knowledge and practices in order to propel them to be subjects of communication in educational environment for a qualitative transformation of being and doing in school.

Adiamento da aposentadoria e o significado do trabalho para servidores de uma universidade federal

This study investigated the intention of the older workers to continue working after state pension age/time. On this way, it explores the relation between this intention and factors related with the meanings of the work and retirement. Specifically, it was examined that factors related to work and non-work are predictors of the intention to continue working, and it was explored if meanings of retirement are linked to this decision. It is a crosssectional mixed methods study, using a survey conducted with 283 federal civil servants of a federal Northeastern University which were near retirement. It envolved an on-line questionnaire, with open-ended questions and the likert-type scale "Older Worker's Intention to Continue Working" (OWICW) of Shacklock and Brunneto (2011), which was validated to the Brazilian version. The quantitative data were analyzed using descriptive and multivariate statistics, specifically procedures for comparing means and coefficients of multiple logistic regression. The qualitative data were analyzed using the lexicographical technique Descending Hierarchical Classification. The findings indicate that most participants want to continue in paid work, and that perception of personal autonomy at work, interpersonal relationships at work, interests outside of work, and flexible working arrangements are significant predictors of intention to continue working. Furthermore, the perception of personal autonomy at work, flexible working arrangements, and the financial incentives are predictors of decision to postpone retirement and remain in the organization. The analysis revealed five patterns of meanings of retirement: "worker's right", "resting", "idle time at home", "new stage in the life course", and "enjoy the use of time”. The decision to postpone retirement is linked to idleness and lack of substitutionary activities work, and the decision to stop working linked to retirement as a life with more quality. The study provides information that can contribute with management policies before the process of retirement decision.

Operações linguístico-discursivas em relatos retextualizados por alunos do ensino fundamental

The following paper attempted to investigate and discuss the possible improvements in the writing of students from the public network in the 6th grade of elementary school. This research was run in the professional master degree In Portuguese Language. Also based upon Genetic Criticism, this study attempting to analyze in which way and in which proportions the alterations done in the texts reveal and perspective capacity in the students as they replace, broad, remove or just move terms in their assignments. We tried to develop our analysis in the pragmatic perspective in which Textual Linguistic is included, investigating the texts and appreciating them as a construction process of meaning. Our theoretical discussion will be based on and socio-interactional conception of language (MARCUSCHI, 2008), as well as in the postulates of Analyze of Discursion (ADAM, 2010, 2008). It has also been used the theoretical assumptions taken from Genetic Criticism which regard the relation between text and genesis, due to the fact that it considers the text and a the result of a construction of progressive elaboration and the writing as an activity of constant movement (DE BIASI, [2000] 2010; GRÉSILLON, 1989; [1990] 2008; [1992] 2002; SALLES, 2008a). To assemble the data in this research we took into consideration the social variables related to the students and the sociocultural context. Nonetheless, this investigation point towards a real classroom situation where we tried to analyze the language functioning in application conditions, thus, giving us authority to describe more precisely the reality we lived in, which provided us with a more attentive look to the observed particularities. This description of the reality appreciated built a path that point to a research of qualitative data approach to which meanings deriving from interpretation were attributed. To conduct this research we resourced to the Action-Research process. The data are comprised of ten personal reports that were created from rewriting assignments, which constitutes a range of twenty texts assessed starting from the linguistic operations acknowledged by Generative Grammar and continued by Lebrave and Grésillon (2009). As result of this analysis, we identified the operation of adding more often than the other ones. The replacement and removal operations display a very close offspring. Nevertheless, the moving operation was scarcely used. These results, besides demonstrating linguistic creativity of the students, revealed that for a text to be seen as “concluded”, the writing student articulates new elaborations through these linguistic operators and that these movements of coming and going, of erasures and amendments contribute significantly for the teacher to approach the relationship the student keeps with his textual and discursive expression, and then, with that, to hold information that eventually provides individual and collective directions in school productions.

O plano de texto e as marcas linguísticas da responsabilidade enunciativa no artigo de opinião do vestibular 2010 da UFRN

With this thesis, we investigate papers produced by candidates to the vestibular 2010 from UFRN related to the (non) taking on of different points of view in the textual zone of the argumentation and counter-argumentation. The candidates had to produce an opinion article about the polemic theme of the security cameras. The corpus of this research contents 100 papers produced by the candidates to the vestibular 2010 from different areas (humans I, humans II, technological I, technological II and biomedical). To this study, we are based on theoretical perspectives from authors of different theories and linguistic fields that dialog among them. In this direction, we follow Bakhtin (1995), Rabatel (2008 a, 2008 b), Guentchéva (1994, 1996, 2011) and Rodrigues, Passeggi e Silva Neto (2010), among others, that are concerned to dialogism, enunciative theories, discuss analyzes, and linguistic of the text. This group of linguistic approach is linked to the Textual Analyze of the Discuss (ADAM, 2011), that conducts analyze of the data of this research. Related to the methodology, we follow the qualitative analyze in an interpretative way. We investigate how the candidate, as a writer, takes on information inserted in his/her paper. With this in mind, this research tries to answer the following questions: (1) How the candidate organizes his/her discuss in respect to the enunciative responsibility? (2) Which linguistic marks conduct to identify the different voices in the texts? (3) How the textual plan is presented in the opinion article? (4) In which part of the textual plan is possible to identify the enunciative responsibility? In this sense, the aims of this study are identify, describe, analyze and interpret the different voices presented in the text and the way the candidate takes on (or not) the different points of view presented in the papers during argumentation and counterargumentation movement. In general, the results reveal that the presence of linguistic marks (connectors, people marks, among others) design the grade of enunciative responsibility of the writer, stimulating his/her involving and taking on enunciative responsibility.
