SABERES E PRÁTICAS DOCENTES EM CURSOS DE LATO SENSU

Segundo dados do INEP (2007) temos cerca de 8.866 cursos de lato sensu no Brasil e, consequentemente, o número de docentes que atuam no ensino superior se torna um crescente, se observarmos os dados do Censo da Educação Superior de 2010, onde foi registrado 345.335 vínculos de funções docentes em exercício nas instituições de educação superior. Baseados nestes dados surgem as seguintes questões: quais são os saberes e as práticas pedagógicas destes docentes diante do ensino no lato sensu? Como os professores que atuam neste segmento, se constituem docentes, tendo em vista que nem sempre a sua formação é pedagógica? A formação para a atuação nesta modalidade é prevista no Artigo 66 da Lei de Diretrizes e Bases da Educação Nacional, que afirma que a preparação para o exercício no magistério superior se fará em nível de pós-graduação, prioritariamente em Programas de Mestrado e/ou Doutorado e sabemos que não há, especificamente, uma indicação de formação pedagógica para a docência. Assim, a investigação sobre as questões acima anunciadas se realizou por meio de uma pesquisa sobre a trajetória formativa e profissional de docentes que atuam no lato sensu, para identificarmos se a falta de formação pedagógica influencia/influenciou seus saberes e práticas docentes, como construíram sua identidade de professor ao longo de sua carreira, e sobre qual a real motivação para tornar-se professor. Os sujeitos da pesquisa são quatro professores que atuam em uma Instituição particular em São Paulo/Capital. Foram realizadas entrevistas semi-estruturadas para a coleta de dados e organização de categorias de análises por meio da metodologia de análise de conteúdo. Esta pesquisa teve também uma contextualização histórica sobre a legislação do lato sensu e uma discussão teórica sobre saberes e práticas docentes direcionadas para o ensino superior. A análise dos dados confirmou a hipótese de que os professores que atuam no lato sensu resgatam seus saberes e práticas de experiências vivenciadas quando eram alunos, tomando como modelo referências que tiveram ao longo de sua trajetória formativa e profissional. Foi constatado que na maioria das vezes, o professor só procura a formação pedagógica após já estar inserido no contexto da atuação no lato sensu, dependendo quase que exclusivamente, de uma busca por iniciativa própria, uma vez que a legislação não pré-determina qual o perfil deste professor para atuação no lato sensu. Constituem-se docentes de maneira gradual e a formação pedagógica é mais uma possibilidade para a atuação, uma vez que em primeiro lugar vem a experiência da prática profissional de sua área de formação de origem.

APRENDIZAGENS NA MODALIDADE EAD: A ÓPTICA DE ALUNOS DO CURSO DE LETRAS DE UMA INSTITUIÇÃO DE ENSINO SUPERIOR DO GRANDE ABC

Com os avanços tecnológicos de comunicação e informação (TICs) e a utilização em larga escala da internet, tem-se uma inovação no processo educativo que pode se valer de instrumentos diferenciados e permitir acesso à informação e à educação para um maior número de pessoas. A partir dessa evolução, a implantação de programas nacionais de Educação a Distância (EAD) no país começou a ocorrer de forma significativa. Esta modalidade acompanha o avanço das tecnologias e a democratização do acesso à educação, expandindo-se de forma visível, conquistando novos espaços e permitindo que o processo da educação aconteça de maneira eficiente, buscando formar discentes críticos e participativos do seu processo de formação educacional. Com base nesta perspectiva, este trabalho teve como objetivo discutir a aprendizagem sob a óptica do aluno de um curso de Letras na modalidade EAD. Realizou-se, para tanto, a contextualização histórica da EAD no mundo, no Brasil e na instituição alvo desta pesquisa. A metodologia utilizada para este fim foi uma pesquisa qualitativa e o corpus de pesquisa são as respostas dos sujeitos participantes a um questionário de caráter exploratório. Foram elaboradas três categorias para análise do conteúdo das respostas Opção pelo curso em EAD: tecnologia versus disponibilidade temporal; Interação via AVA: desvelando o preparo dos atores atuantes na modalidade e Fatores que implicam no processo de aprendizagem na modalidade EAD: autonomia, organização e comprometimento. Alguns aspectos se evidenciaram nesta pesquisa e possibilitaram concluir que a EAD na instituição pesquisada tem buscado contemplar as necessidades existentes nesse cenário, por meio do oferecimento de ações educativas e de recursos tecnológicos que possam oferecer aos alunos uma educação de qualidade, com uma relação de interação contínua, na qual a distância não seja uma limitação. Para tanto, requer dos alunos uma postura de comprometimento, interesse, organização e disciplina, pois dessa forma, as aprendizagens nessa modalidade podem ser tão significativas e eficazes quanto na presencial. Nesse sentido, foi possível inferir também, que os alunos da EAD têm procurado responder a tais exigências adequando-se a elas de forma consciente ao demonstrar, sobretudo, autonomia e visão crítica de que só assim poderão se tornar sujeitos ativos e participativos do processo de construção do próprio conhecimento.

Public scientific communication on Twitter:visual analytic approach

Purpose - The purpose of this paper is to assess high-dimensional visualisation, combined with pattern matching, as an approach to observing dynamic changes in the ways people tweet about science topics. Design/methodology/approach - The high-dimensional visualisation approach was applied to three scientific topics to test its effectiveness for longitudinal analysis of message framing on Twitter over two disjoint periods in time. The paper uses coding frames to drive categorisation and visual analytics of tweets discussing the science topics. Findings - The findings point to the potential of this mixed methods approach, as it allows sufficiently high sensitivity to recognise and support the analysis of non-trending as well as trending topics on Twitter. Research limitations/implications - Three topics are studied and these illustrate a range of frames, but results may not be representative of all scientific topics. Social implications - Funding bodies increasingly encourage scientists to participate in public engagement. As social media provides an avenue actively utilised for public communication, understanding the nature of the dialog on this medium is important for the scientific community and the public at large. Originality/value - This study differs from standard approaches to the analysis of microblog data, which tend to focus on machine driven analysis large-scale datasets. It provides evidence that this approach enables practical and effective analysis of the content of midsize to large collections of microposts.

Contextual semantics for sentiment analysis of Twitter

Sentiment analysis on Twitter has attracted much attention recently due to its wide applications in both, commercial and public sectors. In this paper we present SentiCircles, a lexicon-based approach for sentiment analysis on Twitter. Different from typical lexicon-based approaches, which offer a fixed and static prior sentiment polarities of words regardless of their context, SentiCircles takes into account the co-occurrence patterns of words in different contexts in tweets to capture their semantics and update their pre-assigned strength and polarity in sentiment lexicons accordingly. Our approach allows for the detection of sentiment at both entity-level and tweet-level. We evaluate our proposed approach on three Twitter datasets using three different sentiment lexicons to derive word prior sentiments. Results show that our approach significantly outperforms the baselines in accuracy and F-measure for entity-level subjectivity (neutral vs. polar) and polarity (positive vs. negative) detections. For tweet-level sentiment detection, our approach performs better than the state-of-the-art SentiStrength by 4-5% in accuracy in two datasets, but falls marginally behind by 1% in F-measure in the third dataset.

Adapting sentiment lexicons using contextual semantics for sentiment analysis of Twitter

Sentiment lexicons for sentiment analysis offer a simple, yet effective way to obtain the prior sentiment information of opinionated words in texts. However, words' sentiment orientations and strengths often change throughout various contexts in which the words appear. In this paper, we propose a lexicon adaptation approach that uses the contextual semantics of words to capture their contexts in tweet messages and update their prior sentiment orientations and/or strengths accordingly. We evaluate our approach on one state-of-the-art sentiment lexicon using three different Twitter datasets. Results show that the sentiment lexicons adapted by our approach outperform the original lexicon in accuracy and F-measure in two datasets, but give similar accuracy and slightly lower F-measure in one dataset.

Designing an E-Mail Prototype to Enhance Effective Communication and Task Management: A Case Study

This paper deals with communicational breakdowns and misunderstandings in computer mediated communication (CMC) and ways to recover from them or to prevent them. The paper describes a case study of CMC conducted in a company named Artigiani. We observed communication and conducted content analysis of e-mail messages, focusing on message exchanges between customer service representatives (CSRs) and their contacts. In addition to task management difficulties, we identified communication breakdowns that result from differences between perspectives, and from the lack of contextual information, mainly technical background and professional jargon at the customers’ side. We examined possible ways to enhance CMC and accordingly designed a prototype for an e-mail user interface that emphasizes a communicational strategy called contextualization as a central component for obtaining effective communication and for supporting effective management and control of organizational activities, especially handling orders, price quoting, and monitoring the supply and installation of products.

Semantic patterns for sentiment analysis of Twitter

Most existing approaches to Twitter sentiment analysis assume that sentiment is explicitly expressed through affective words. Nevertheless, sentiment is often implicitly expressed via latent semantic relations, patterns and dependencies among words in tweets. In this paper, we propose a novel approach that automatically captures patterns of words of similar contextual semantics and sentiment in tweets. Unlike previous work on sentiment pattern extraction, our proposed approach does not rely on external and fixed sets of syntactical templates/patterns, nor requires deep analyses of the syntactic structure of sentences in tweets. We evaluate our approach with tweet- and entity-level sentiment analysis tasks by using the extracted semantic patterns as classification features in both tasks. We use 9 Twitter datasets in our evaluation and compare the performance of our patterns against 6 state-of-the-art baselines. Results show that our patterns consistently outperform all other baselines on all datasets by 2.19% at the tweet-level and 7.5% at the entity-level in average F-measure.

Elaboração de uma unidade de ensino potencialmente significativa em Química para abordar a temática água

The evidence of the water theme in news reports is configured as an important topic of interest to contextualize, problematize and/or generate meaning in the midst of discussion of a content from different levels of education and/or disciplines of basic education. The possibilities to use this theme in classroom is also highlighted in Brazilian official documents that guide the practice of teachers of all Brazilian curricular components of this educational level. So, the theme water can be used as subsidy to teach chemistry, since contextualises the teaching of this discipline aiding in the discussion of different chemical concepts. In this perspective, the meaningful learning theory, developed by David Ausubel, has constructivist nature and says that an individual learns significantly when he can relate new information with a specific knowledge structure that integrates the prior knowledge of its structure. In this sense, the use of water as a theme for the approach prior knowledge of chemical concepts has already been characterized as an important topic that can give meaning to the content of education in chemistry. In this dissertation, a teaching unit potentially significant (TUPS) is presented based on meaningful learning theory of David Ausubel approaching the theme water. approaching the theme water. The unit was used in a class of thirty-five students of the 2nd year of high school, a public school in the city of Extremoz-RN, metropolitan region of Natal / RN. Through it was possible to discuss an issue of interest to students of the school to address the chemical contents, such as solutions, physicochemical aspects and stages of water treatment. At first, an initial questionnaire was used to identify the students' previous ideas on the topic under study to the concept of chemical solutions. It was subsequently developed and implemented a series of activities based on students' ideas. To subsidize the sequence, it was prepared four booklets that worked the content of chemical solutions, contextualizing the theme water. The results of this work showed that the alternative conceptions that students have about concepts related to the chemical solutions are similar to the ideas of other students presented in the literature and that the development of the TUPS, allied to the contextualization strategy with the theme water, not only motivated the students for the teaching of chemical content, as yet provided the learning of chemical concepts not in isolation, but making a connection between their ideas and experiences with scientific knowledge. To this, beyond of dialogued lectures, were also used strategies as experimental activities, problem solving, group discussions and construction of concept maps. The final evaluation of the unit was conducted by a questionnaire based on the Likert scale, answered individually by students, who approved the unit as conducive to teaching and learning of chemistry process

Infoestrutura: um sistema em nuvem para prover contexto como serviço no cenário de internet das coisas integrado a ambientes veiculares

Through numerous technological advances in recent years along with the popularization of computer devices, the company is moving towards a paradigm “always connected”. Computer networks are everywhere and the advent of IPv6 paves the way for the explosion of the Internet of Things. This concept enables the sharing of data between computing machines and objects of day-to-day. One of the areas placed under Internet of Things are the Vehicular Networks. However, the information generated individually for a vehicle has no large amount and does not contribute to an improvement in transit, once information has been isolated. This proposal presents the Infostructure, a system that has to facilitate the efforts and reduce costs for development of applications context-aware to high-level semantic for the scenario of Internet of Things, which allows you to manage, store and combine the data in order to generate broader context. To this end we present a reference architecture, which aims to show the major components of the Infostructure. Soon after a prototype is presented which is used to validate our work reaches the level of contextualization desired high level semantic as well as a performance evaluation, which aims to evaluate the behavior of the subsystem responsible for managing contextual information on a large amount of data. After statistical analysis is performed with the results obtained in the evaluation. Finally, the conclusions of the work and some problems such as no assurance as to the integrity of the sensory data coming Infostructure, and future work that takes into account the implementation of other modules so that we can conduct tests in real environments are presented.

Criminalização do porte de drogas para consumo pessoal: uma perspectiva jurídico-constitucional

This dissertation has the main objective to assess the legal and constitutional legitimacy of the legislative state act that criminalizes the conduct of carrying drugs for own consumption - in the case of Brazil, art. 28 of the Federal Law n.º 11.343 of August 23rd, 2006. Therefore, it is done, initially, a contextualization, pointing the main regulatory frameworks, internal and external, of what is conventionally called prohibition in the matter of drugs, as well as the different species of liberalizing initiatives today on an upward trend in the international scenario. Then analyzes the state intervention in question in the light of references of human dignity, freedom and privacy, emphasizing, in the point, among other contributions, the various precedents of foreign constitutional jurisdiction over the theme. Immediately thereafter, confronts the policy in screen with what is perhaps, these days, the main control mechanism of the restrictive measures of fundamental rights, namely the proportionality test, here represented by classical elements of appropriateness, necessity and proportionality in the strict sense. After that, it examines the criminalization on the agenda before the parameter of equality and the general interests of health and public safety. Based on theory and empirical enrolled in the development, it is concluded, finally, the unconstitutionality of the option of the ordinary legislature to impose criminal penalties on users - problematic or not - of substances or products capable of causing physical or psychological dependence.

A conduta judicial ética teórica e aplicada contida em princípios e regras deontológicos abrangidos pelo sistema constitucional

Research on Legal Deontology dedicated to theoretical and applied ethics on judicial conduct grounded in legal principles and rules set out in the Constitution of the Federative Republic of Brazil and the Organic Law of the National Judiciary, also contemplating propositional instruments covered by the constitutional system, which conveys behavioural paradigms inserted in the Bangalore Principles of Judicial Conduct, in the Universal Statute of the Judge and in the Latin-American Code of Judicial Ethics, as well as highlight the influence of those instruments in the Brazilian Ethical Code of the Magistrates and in the official complementary training of judges in charge of Judiciary Schools. The study provides the theoretical influxes of moral norm, passing by behavioural social norm to consolidate the ideal standards of judicial conduct into legal standards and related instruments. The Legal Deontology directed to the ethical judicial conduct is confronted with the stereotype that society expressed in relation to the judge's person, who is the political agent that interprets the law for making decisions which directly influences the realization of access to justice, that is constitutionally guaranteed to all. Core values inserted in the constitutional system intended to discipline the judicial conduct are presented and analysed under a critical view, since they are enclosed in prescriptive language that conveys behavioural aspects open to interpretation and which compliance is revealed as a proposition focused on promoting a better solution of interest’s conflicts under the responsibility of those who constitute the distinctive corporation of the Judiciary. The theme’s contextualization also focuses on applied ethics, based on the approach of normative and propositional instruments of deontological content, still focusing on the study of real cases examined by the Brazilian National Council of Justice, as part of its correctional goals.

A educação a distância e a formação docente

This study was guided by the following question: Is it possible to prepare good teachers for Basic School in Distance Learning (DL) online? The over all objective of this study was to identify and systematize the essential knowledge and skills for the practice of teaching in basic education as well to investigate whe ther the Distance Learning courses which train and prepare future teachers include all the knowledge and skills necessary for teaching practice. This is a qualitative the oretical and bibliographic research that aims to analyze the current stageof the knowledge on this theme. We selected recent papers on this subject, in order to study what has been written by the authors as well to know which are their significant findings. Data were collected from dissertations, thesis and books published on the theme. Preliminarily, the theme of the presentation and contextualization has been made and the argument about the relevance of the study for education. In the second section, we present an overview of the Distance Education in Brazil: coargumentncepts, characteristics, emergence, evolution and regulation. The third section the working environmentin training teachers and students in on line education, targeting to be familiar to Learning Virtual Environments (LVE), analyzing how these new learning spaces are settled and how students and teachers be have in front of the new settings of teaching and learning using Information and Communication Technologies (ICT). In the fourth section aimed to identify which are the essential knowledges and skills that the teacher must master in order to work competently as well to discover which are the personal and professional characteristics of a good teacher in the XXI century. The fifth section studied and analyzed the current situation with in Distance Education is carried out in Brazil. We identified the most significant contributions of Distance Learning to Brazilian Education System in order to contribute to advances in the debate on the effectiveness of teacher training courses in distance education mode online.Finally in the sixth section were made final remarks and presented the study results.

Uma leitura de gênero nos contos "Prelúdio", "Na baía" e "A casa de bonecas", de Katherine Mansfield

This work aims to analyze the short stories “Prelude”, “At the Bay” and “The Doll’s House”, by Katherine Mansfield under the prism of the gender studies (mainly on the works of Joan Scott and Elisabeth Badinter). To reach such objective, and based on the feminist criticism works (especially those of Elaine Showalter and Toril Moi), we analyzed the three stories, which are from the writer’s so-called “family phase”. The present work contains a bibliographical contextualization of Mansfield’s modernist work under three main aspects: modernism, the short story and women’s writing/writings on women. From the analysis of the three short stories, we observed that questions of gender, representation and identity were depicted by means of the preponderance of female characters from all ages, marital statuses and classes. At the end it was possible to verify how Mansfield works contributed to a reflection about places and roles occupied by women in turn of the XIX and XX Centuries, whereas how this author was also in search for her own identity as a woman and as a writer, exactly in a context when women writers and women’s writings started to become more visible face to a predominantly masculine literary canon.
