This study investigates teacher training and cognitive practice of teachers in a Basic Education school that adopted the Project One Computer per Student (OCS) in their school routine. Its relevance consists in provide directions for the continuation of training activities on the Project and guide the teachers with their pedagogical practices using the laptop model one to one. The thesis defended is that the educator formation for social using of digital media (specially the laptops from the Project UCA) gives space to establish new sociotechnical relationships, of new social and professionals practices, new identitary components and a process of reflexivity and knowledge reconstruction to teach. We reaffirm the importance of reflexivity and appropriation of digital culture for the better development of teaching practice using the Information and Communication Technologies (ICTs), giving focus to the aspects of social and professional use of the technology. The study is part of the qualitative aspect and is a procedural tracking based on principles of ethnographic research. As procedures and methodological tools, were used: intensive observation of school environments, documental analysis, focal group, semi-structured questionnaires and semi-structured individual interviews. The research was held in a public school in the city of Parnamirim - RN. The subject sample relates to 17 teachers, coming from the elementary school I and II, Youth and Adult Education and High School, who went through the process of training UCA and having entered the laptops in their teaching. The research corpus is structured based on the messages built into the process of data collection and is analyzed based on principles of Content Analysis, specified by Laurence Bardin (2011). Was taken as theoretical reference studies by Tardif (2000; 2011), Pimenta (2009), Gorz (2004, 2005), Giddens (1991), Dewey, J. (1916), Boudieu (1994; 1999), Freire (1996; 2005), among others. The analysis indicates a process of reconstruction / revision of knowledge to teach and work in digital culture, being these knowledges guided by the experience of the subjects investigated. The reconstructed knowledges will be revealed from a categorization process. The following groups of knowledges: "technical knowledges", "didactic-methodological knowledges and knowledges of professionalization" were built on the assumption of ownership of digital culture in the educational context. The analysis confirms the appearance of new ways of sociability when acquiring other forms of acting and thinking ICTs, despite the environment adverse to the reflexivity shared among the teachers. Also reveals, based on the ownership concept present on the data analysis, the construction of meanings of belonging and transformation of individuals into social routes from the interweaving of the teaching practice with the digital culture. Emphasizes, finally, the importance of a training for use of ICTs that exceeds the instrumentation, in other words, what we call "technical knowledges", but taking on its structural basis the shared reflection, the opening for the ressignificance (new meaning) and reconstruction of new knowledges and practices and that really allows, to the teacher, the living of an experience capable of providing socio-technical transformations of their relationships

The spread of the Web boosted the dissemination of Information Systems (IS) based on the Web. In order to support the implementation of these systems, several technologies came up or evolved with this purpose, namely the programming languages. The Technology Acceptance Model TAM (Davis, 1986) was conceived aiming to evaluate the acceptance/use of information technologies by their users. A lot of studies and many applications have used the TAM, however, in the literature it was not found a mention of the use of such model related to the use of programming languages. This study aims to investigate which factors influence the use of programming languages on the development of Web systems by their developers, applying an extension of the TAM, proposed in this work. To do so, a research was done with Web developers in two Yahoo groups: java-br and python-brasil, where 26 Java questionnaires and 39 Python questionnaires were fully answered. The questionnaire had general questions and questions which measured intrinsic and extrinsic factors of the programming languages, the perceived usefulness, the perceived ease of use, the attitude toward the using and the programming language use. Most of the respondents were men, graduate, between 20 and 30 years old, working in the southeast and south regions. The research was descriptive in the sense of its objectives. Statistical tools, descriptive statistics, main components and linear regression analysis were used for the data analysis. The foremost research results were: Java and Python have machine independence, extensibility, generality and reliability; Java and Python are more used by corporations and international organizations than supported by the government or educational institutions; there are more Java programmers than Python programmers; the perceived usefulness is influenced by the perceived ease of use; the generality and the extensibility are intrinsic factors of programming languages which influence the perceived ease of use; the perceived ease of use influences the attitude toward the using of the programming language

Deaf people have serious difficulties to access information. The support for sign languages is rarely addressed in Information and Communication Technologies (ICT). Furthermore, in scientific literature, there is a lack of works related to machine translation for sign languages in real-time and open-domain scenarios, such as TV. To minimize these problems, in this work, we propose a solution for automatic generation of Brazilian Sign Language (LIBRAS) video tracks into captioned digital multimedia contents. These tracks are generated from a real-time machine translation strategy, which performs the translation from a Brazilian Portuguese subtitle stream (e.g., a movie subtitle or a closed caption stream). Furthermore, the proposed solution is open-domain and has a set of mechanisms that exploit human computation to generate and maintain their linguistic constructions. Some implementations of the proposed solution were developed for digital TV, Web and Digital Cinema platforms, and a set of experiments with deaf users was developed to evaluate the main aspects of the solution. The results showed that the proposed solution is efficient and able to generate and embed LIBRAS tracks in real-time scenarios and is a practical and feasible alternative to reduce barriers of deaf to access information, especially when human interpreters are not available

Este estudo se propõe a analisar os mandatos das subsidiárias de empresas transnacionais (ETNs) no estrangeiro por intermédio dos mecanismos de alocação das atividades de pesquisa e desenvolvimento (P&D) entre os centros descentralizados de pesquisa. Iniciamos o trabalho com a apresentação de uma síntese das diferentes perspectivas encontradas na literatura econômica sobre a subordinação (ou condicionamentos) da autonomia administrativa e tecnológica das filiais. Tal síntese permite estabelecer uma hierarquia entre as subsidiárias e uma tipologia para evolução (retrocesso) de mandatos construída, principalmente, para as ETNs estruturadas em forma de rede corporativa. A seguir, a partir de pesquisas realizadas sobre as atividades dos laboratórios de P&D da indústria de equipamentos de telecomunicações no Brasil, procuramos mostrar que: a) a descentralização das atividades tecnológicas é um fato que não está restrito apenas aos países centrais; b) as tecnologias de informação permitiram que as subsidiárias no país se integrassem aos laboratórios centrais das ETNs, dando-lhes condições de desenvolver e participar de outras atividades tecnológicas, além das tradicionais funções de adaptação de processo e de produtos.

Estudiosos dos campos da Educação, da Linguística Aplicada e da Formação de Professores de Línguas insistem hoje na grande importância da inclusão de Tecnologias de Informação e Comunicação (TICs) na formação inicial, bem como na necessidade de promover o desenvolvimento do pensamento crítico-reflexivo dos futuros professores. Tomando como pressupostos teóricos estudos acerca das características da sociedade de informação, dos ambientes virtuais e da formação de professores, este trabalho tem como objetivo discutir possibilidades oferecidas pela plataforma Moodle de aprendizagem na formação inicial de professores de alemão. Para tanto, apresentaremos diferentes formas de uso de ambientes virtuais e de ferramentas neles disponíveis, que demonstraram ser de grande valor no processo de formação de licenciandos, tanto em língua alemã, quanto durante suas práticas iniciais. As experiências apontam para um valor inestimável de ambientes virtuais no acompanhamento de licenciandos no processo de aprendizagem da língua e nas primeiras experiências com a docência.

The interdisciplinary nature of Astronomy makes it a field of great potential to explore various scientific concepts. However, studies show a great lack of understanding of fundamental subjects, including models that explain phenomena that mark everyday life, like the phases of the moon. Particularly in the context of distance education, learning of such models can be favored by the use of technologies of information and communication. Among other possibilities, we highlight the importance of digital materials that motivate and expand the forms of representation available about phenomena and models. It is also important, however, that these materials promote the explicitation of student's conceptions, as well as interaction with the most central aspects of the astronomical model for the phenomenon. In this dissertation we present a hypermedia module aimed at learning about the phases of the moon, drawn from an investigation on the difficulties with the subject during an Astronomy course for teaching training at undergraduate level at UFRN. The tests of three semesters of course were analyzed, taking into account also the alternative conceptions reported in the literature in astronomy education. The product makes use of small texts, questions, images and interactive animations. Emphasizes questions about the illumination of the Moon and other bodies, and their relationship to the sun, the perception from different angles of objects illuminated by a single source, the cause of the alternation between day and night, the identification of Moon's orbit around the Earth and the occurrence of the phases as a result of the position of observing it, and the perception of time involved in the phenomenon. The module incorporated considerations obtained from interviews with students in two poles where its given presential support for students of the course, and subjects from different pedagogical contexts. The final form of the material was used in a real situation of learning, as supplementary material for the final test of the discipline. The material was analyzed by 7 students and 4 tutors, among 56 users, in the period in question. Most students considered that the so called "Lunar Module" made a difference in their learning, the animations were considered the most prominent aspect, the images were indicated as stimulating and enlightening, and the text informative and enjoyable. The analysis of learning of these students, observing their responses to issues raised at the last evaluation, suggested gains in key aspects relating to the understanding of the phases, but also indicates more persistent difficulties. The work leads us to conclude that it is important to seek contributions for the training of science teachers making use of new technologies, with attention to the treatment of computer as a complementary resource. The interviews that preceded the use of the module, and the way student has sought the module if with questions and/or previous conflicts - established great difference in the effective contribution of the material, indicating that it should be used with the mediation of teacher or tutor, or via strategies that cause interactions between students. It is desirable that these interactions are associated with the recovery of memories of the subjects about previous observations and models, as well as the stimulus to new observations of phenomena

This study focuses on the teaching and learning of English based on a new theoretical perspective concerning the Zone of Proximal Development (ZPD), which points to the apprehension of metacognitive processes as the way to reach learning autonomy. The theoretical set underline this study is those of a new pedagogy based on the symbiosis of Bruner‟s (2002) and Freire‟s (2009) concepts and in the metacognitive theory. In a social context dominated by the Communication and Information Technologies (CIT), the integration between teacher and learners with the support of the internet has been used as the way to operationalize this new emergent proposal of the theoretical perspectives. The analyses have been conducted through Systemic and Integral Action Research. The results at the end of this study corroborate our hypothesis that the enlargement of spontaneous knowledge of the learners can facilitate the understanding of scientific concepts, stimulating their metacognition and thus promoting their autonomy.

Over the last decades, the digital inclusion public policies have significantly invested in the purchase of hardwares and softwares in order to offer technology to the Brazilian public teaching institutions, specifically computers and broadband Internet. However, the teachers education to handle these artefacts is put away, even though there is some demand from the information society. With that, this dissertation chooses as an object of study the digital literacy practices performed by 38 (thirty-eight) teachers in initial and continuous education by means of the extension course Literacies and technologies: portuguese language teaching and cyberculture demands. In this direction, we aim at investigating the digital literacy practices of developing teachers in three specific moments: before, while and after this extension action with the intent to (i) delineate the digital literacy practices performed by the collaborators before the formative action; (ii) to narrate the literacy events made possible by the extension course; (iii) to investigate the contributions of the education course to the collaborators teaching practice. We sought theoretical contributions in the literacy studies (BAYNHAM, 1995; KLEIMAN, 1995; HAMILTON; BARTON; IVANIC, 2000), specifically when it comes to digital literacy (COPE, KALANTZIS, 2000; BUZATO, 2001, 2007, 2009; SNYDER, 2002, 2008; LANKSHEAR & KNOBEL, 2002, 2008) and teacher education (PERRENOUD, 2000; SILVA, 2001). Methodologically, this virtual ethnography study (KOZINETS, 1997; HINE, 2000) is inserted into the field of Applied Linguistics and adopts a quali-quantitative research approach (NUNAN, 1992; DÖRNYEI, 2006). The data analysis permitted to evidentiate that (i) before the course, the digital literacy practices focused on the personal and academic dimensions of their realities at the expense of the professional dimension; (ii) during the extension action, the teachers collaboratively took part in the hybrid study sessions, which had a pedagogical focus on the use of ICTs, accomplishing the use of digital literacy practices - unknown before that; (iii) after the course, the attitude of the collaborator teachers concerning the use of ICTs on their regular professional basis had changed, once those teachers started to effectively make use of them, promoting social visibility to what was produced in the school. We also observed that teachers in initial education acted as more experienced peers in collaborative learning process, offering support scaffolding (VYGOTSKY, 1978; BRUNER, 1985) to teachers in continuous education. This occurred because of the undergraduates actualize digital literacy practices were more sophisticated, besides the fact being integrate generation Y (PRENSKY, 2001)

This thesis has as its object the Markers Organization Standard Narrative Discourse (MON), from its occurrence in oral and written corpora of different realizations of narrative discourse, considering its locus of occurrence in the narrative and discursive functioning. The research is guided by the Functional Linguistic Usage-Based, approach to which the organization of language is directly linked to the user experience, so that grammar is shaped by discourse. We examined only the narrative portions of Experience Reports, Tales and Legends in the oral and written, as follows: 3 inquiries Corpus Reports Remaining Quilombo (RN); 11 Corpus Legends legends of the Amazon, 14 Tales of Corpus Tales Brazilians and 21 Reports of experiences of Corpus and Discourse Grammar, with about 10,000 words in each corpus. A total of 22 markers were identified, which were: (1) classified according to the locus of occurrence in the narrative structure, as Labov (1972), (2) associated, according to the type of pattern that occur in narrative discourse, (3) described from the discursive function they perform. The research has relevance to the extent it is based speech analysis and offers proposals for productive teaching of mother tongue in which students and teachers can, grounded in language studies, consider living language, as an object of study, based on the National Curriculum Guidelines (OCN) and making use of New Technologies of Information and Communication (NTIC)

Considering the following conditions: (1) the fluency demands of students in an undergraduate program in Languages and Literatures/English in the Amazon region; (2) the listening and speaking needs of pre-service teachers of English as a Foreign Language (EFL); (3) my continuing education as a professor of EFL and my academic literacy as a teacher-researcher and pre-service-teacher trainer, this study, which is based on Narrative Inquiry, reports on a teacher experience of working didactically with oral genres through podcasting an activity that emerged with the advent of Information and Communication Technology (ICT). Through this process, I engage with some theorists who promote teaching as a process that is driven by a concept of language as social practice. Subsequently, I make use of the notions of context of culture and context of situation, derived from Systemic Functional Linguistics, as well as the concept of genre and register derived from the perspective of this theory. Based on these principles and beliefs, the Amazon region constitutes the register (situation) of the genres used in this study. These principles also provide, opportunities for building learning strategies appropriate to this local context, and also to teach listening and speaking skills from a task-based approach. During the experience, based on the reflective teacher-education model, the participants produced narratives about the process, which I then analyzed according to Ely, Vinz, Downing and Anzul (2001), who propose possibilities of composing meanings in Narrative Inquiry. Based on this perspective, I discuss the following topics, which were highly emphasized in the participants narratives: the lack of didactic activities using oral genres; the relevance of context within teacher education; and collaborative work as a strategy to overcome gaps in digital literacy, language fluency and teaching skills. The meanings I thereby compose point to a paradigm shift in English language teaching within this context. I also argue for a pedagogical practice that is engaged with historical and socio-cultural issues, and with the development of language skills, also one that promotes the implementation of ICTs at the very start of teacher training programs, adopting teaching and learning strategies that correspond to the demands of fluency in this particular context, and deficiencies imposed by geographical isolation

This research aimed to analyze the dynamics established between the activity of the teacher in Distance Education (DE) and professional gender of teaching, in terms of impact of DE in teacher s usual professional activity. Previous studies showed that one of the central discussions concerning DE refers to the role that the teacher is called to perform. The present research, based on theoretical and methodological assumptions issued from Clinic of Activity, analyzed the impact referred above. This central aim was operationally executed along three main stages: 1) survey study for description of socio-professional profile of teachers working in DE in two universities from Natal (RN-Brazil), 2) clinical analysis of professional activity of teachers working in DE, taking into account four simultaneous levels of psychological constitution and development of human activity: personal, interpersonal, transpersonal and impersonal; 3) analytical focus on transpersonal context in order to understand the influence of pedagogical practice in DE on professional gender of teaching. Documental research, audio recorded voice data and a multiple choice Likert scale questionnaire concerning socio-professional information were used as procedural tools. The qualitative-clinical procedural tool of instruction to the double , firstly proposed by Clinic of Activity research group, was used in order to obtain oral productions concerning professional activity. Data issued from stage 1 (n=70, 28 men and 41 women) was submitted to descriptive and inferential statistical analyzes. 65.7% of the sample worked in a public institution, 30% in a private institution, and 4.3% in public and private institutions. 31.4% of the sample of participants was formed by teachers having a master degree, 28.6% were doctors and 26.3% had degrees of specialists. 54.3% of participants acted as remote tutor, and 44.3% were regents teachers. After descriptive multidimensional cluster analysis, two groups emerged (remote tutors and regents teachers), the most important variables in terms of contributions to this distinction being: professional function, level of graduate formation, level of income, activities and forms of entry in DE. Clinical analysis of data produced by two participant-teachers of each group, issued from instruction to the double technique, was performed. This analysis indicated the existence of different models of distance education. A general concern referring to the need of both taking into account information technology and pedagogical attitudes was detected. On the other hand, participant-teachers considered that participation in DE activities could bring relevant contributions to general professional gender of teaching. . Finally, teachers warned against certain formats of organization of teachers professional activity, as found in the domain of DE, since these activities could promote the intensification and individualization of teachers` work activity, and even the worsening of relations, rather than exchanges and shares through collective bargaining. This process could compromise the renew of the professional gender, by losing its historical roots and diminishing activity possibilities of teachers in their labor context

O presente estudo tem como objetivo compreender os sentidos da experiência de jovens e adultos com a interação social virtual, partindo de suas narrativas. Inspiradas nas ideias de Martin Heidegger, especialmente em seu seminário A Questão da Técnica , refletiremos sobre os modos de ser-com, em tempos de tecnologia, internet, consumo e hipermodernidade, contexto deste estudo, onde as coisas são vivenciadas em seu extremo (hiperconsumo, hipercorpo, hipermercado, hipercartões). Neste cenário, a Internet e as Tecnologias de Informação e Comunicação estão mediando, cada vez mais o contato do homem com o mundo, reconfigurando a vida em sociedade. Diante disso, apresentamos A Era do Click , em que são possibilitados novos meios de estar com os outros. Este é um estudo qualitativo, baseado na fenomenologia de Heidegger, por ser favorecedora da compreensão dos sentidos da experiência em relação à questão problematizada. Como estratégias de pesquisa foram utilizadas sondagem de campo e entrevistas individuais, inspiradas nas narrativas de Walter Benjamin. Cinco colaboradores relataram suas experiências de ser-com no mundo virtual. A partir de seus relatos foi possível compreender que o espaço virtual se revela como mais um lócus, dentre tantos, no cotidiano do ser do homem, em que emergem diferentes modos de ser-com. Dependendo de sua abertura, a proximidade ou o distanciamento tornam-se relativos, do mesmo modo que o pessoal e o impessoal, o próprio e o impróprio. Além disso, tornou-se claro que, a virtualidade pode ajudar a lidar com a solidão e a angústia temporariamente, da mesma forma que pode tornar-se uma barreira para um contato mais aprofundado e autêntico com os outros. Os colaboradores demonstraram uma atitude de serenidade, um poder dizer sim e não simultaneamente à técnica moderna, além de uma postura de meditar sobre os modos como se conectam. Questionamos as implicações em longo prazo da virtualização do contato, estimulando novos estudos, sob a luz da fenomenologia heideggeriana

In today`s society the use of so-called information technology and communication (ICT), is promoting a revolution in the forms of teaching and learning through the methods of distance learning courses, especially in higher education. Studies show that students in this way have great difficulties in the learning process, especially when dealing with experimental subjects that require high power of abstraction as chemistry. The goal of this work is to promote improvement in the teaching and learning in the discipline Chemistry of Life offered for the Bachelor`s Degree in Chemistry in distance UFRN. For this we analyzed evidence of the semester 2011.2, in order to identify what are the main difficulties of the students on the assessments. That`s why video lessons related to matters that create the majority of difficulties for students were developed, the final product this work. Being obtained the improvements by video classes in the learning process of the students, from a questionnaire answered by the students in the virtual learning environment, and from their success rate at the end of the course

Desde o final do século XX, as novas formas de produção documental e as novas tecnologias de informação apresentadas à Arquivística têm levado os profissionais da informação a repensar os conceitos e princípios arquivísticos postulados nos antigos manuais da área. Nesse contexto, destaca-se a produção arquivística canadense, que transformou o país em solo fértil para as discussões que circundam a disciplina na contemporaneidade, representando muito bem as necessidades colocadas pelos novos meios de produção documental aos arquivistas na sociedade da informação, redescobrindo princípios e (re) definindo conceitos, métodos e critérios para a criação, manutenção e uso de documentos em meio tradicional e eletrônico. Foi notadamente na década de 1980, que um novo paradigma se enunciou na área e, a partir dele, três correntes emergiram: a Arquivística Integrada - enunciada pela Escola de Québec - que propõe a reintegração da disciplina por meio do ciclo vital dos documentos e uma possível aproximação com a Ciência da Informação, graças à incorporação do termo informação orgânica registrada, como substituição ao termo documento de arquivo; a Arquivística Funcional ou Pós-Moderna, enunciada por Terry Cook - que propõe uma renovação e reformulação dos princípios e conceitos originais da disciplina, adotando a corrente Pós-moderna como pano de fundo; e a Diplomática Arquivística, enunciada primeiramente na Itália por Paola Carucci, mas desenvolvida e reformulada na América do Norte por Luciana Duranti, que busca, por meio do estudo da Diplomática, estabelecer critérios para a crítica textual dos documentos contemporâneos, garantindo ao método diplomático um posto fundamental na Arquivística contemporânea. A vista de tais aspectos, analisa-se, comparativamente, o universo epistemológico dessas três abordagens arquivísticas canadenses, enquanto perspectivas emergentes para a construção de uma disciplina contemporânea, capaz de dar conta dos novos processos de produção, organização e uso da informação orgânica registrada.

Considerando a potencialidade apresentada pelas tecnologias de informação e comunicação na atualidade este estudo aponta as formas pelas quais grupos sociais mobilizados em torno de uma vinculação étnica podem se servir do aparato da Internet, em especial do World Wide Web, para divulgar aspectos de sua cultura e modo de vida. Trata-se de grupos dedicados ao ensino, transmissão, preservação e disseminação da tradição gaúcha vinculados aos Centros de Tradições Gaúchas (CTG). Especificamente, este artigo apresenta como os tradicionalistas gaúchos estabelecem suas redes sociais na Internet, constituindo comunidades virtuais em torno do tema cultura e tradição gaúcha, fazendo uso dos serviços da Web 2.0. Abordam-se neste estudo experiências que indicam que o terreno virtual é fértil e possível de transformar e revolucionar o campo das tradições, sua preservação, disseminação e (re)invenção. No contexto de modernidade tardia esse recurso não pode ser descartado. Independente da análise se situar no campo econômico, político ou cultural, entre tantos outros, o fato é que a Internet se constitui num meio eficaz e abrangente de transmitir, ensinar e preservar conteúdos de todos os tipos.
