Educação profissional e tecnológica de turismo no Brasil: análise através da percepção de docentes da rede federal de educação

The increasing pace of technological change and innovation in the labor market are important landmarks that contribute to accelerate the improvement of vocational and technological education. The need to analyze the educational processes is correlated with this dynamic in order to respond to the pedagogical processes and inherent to the labor market needs in evidence. This research theme is centered on targeted education process for tourist activity that is premised on improving the quality of services, taking as analysis parameter technological higher education in the federal education network (IF), covering the design, similarity and the differences in the courses offered, the axis of Tourism, Hospitality and Leisure instituted by the National catalog Technological Colleges and the National Science and Technology Department in Brazil. The research also aims to investigate the design and implementation of these upper and search courses emphasize the importance of training for students. The research is exploratory qualitative from survey data on the websites of the Ministry of Education, was adopted as a research procedure the questionnaire sent to coordinators via institutional email courses, to collect data in order to obtain results about Technological Education Federal Education Network. The survey results show that most courses offered by technological higher education in the federal education network (IF) is the Tourism Management, we noted that this option is the result of the ease in assembling the structure of the courses in relation to others; teachers have this type of education a more practical option for students coming to the conclusion that the courses undergo a fragile process, stating that the formation lies only in the student's interest in obtaining the higher diploma course without concern for quality this academic background, demand for courses is by being fast graduation. Even as a result of the design and development of Political and Pedagogical projects it was found that they are built in the most collegial many of them without the participation of a pedagogue; about the permanence of the student identified a high dropout rate, occurring in some campuses to migration to the traditional higher education, a BA in tourism. Thus, this work aimed to contextualize the technological higher education in tourism, presenting the reality of the current situation, aiming to discuss the phenomenon from the description made by all subjects and the research object, knowledge of which is due to experience the federal education network that was able to bring the essence of the matter.

O jogo dos discos: o uso da experimentação como suporte para o ensino da probabilidade

In this paper we propose a class for introducing the probability teaching using the game discs which is based on the concept of geometric probability and which is supposed to determine the probability of a disc randomly thrown does not intercept the lines of a gridded surface. The problem was posed to a group of 3nd year of the Federal Institute of Education, Science and Technology of Rio Grande do Norte - Jo~ao C^amara. Therefore, the students were supposed to build a grid board in which the success percentage of the players had been previously de ned for them. Once the grid board was built, the students should check whether that theoretically predetermined percentage corresponded to reality obtained through experimentation. The results and attitude of the students in further classes suggested greater involvement of them with discipline, making the environment conducive for learning.

Recomendações para um sistema de sinalização tátil a partir de abordagens ergonômicas e da percepção do deficiente visual para o Campus Parnamirim do IFRN

This study reports recommendations for a tactile and graphic wayfinding system aiming to offer more orientability and mobility for visually impaired people (blindness and low vision) at Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN), Parnamirim Campus. It was necessary to focus on visual impaired people and approach concepts like orientation and accessibility at the built environment. In order to provide the comprehension of a complex social phenomenon and preserve the meaningful characteristics of the events, this research has developed a single case study in which elements of Post Occupation Evaluation have been used. Its purpose was to allow not only a technical analysis, but also the user perception about the space in use. The chosen tool to collect the user’s opinions and considerations was the Walk Together Method. The collected and analyzed information has demonstrated that, although Parnamirim Campus has implemented some interventions in relation to the spatial accessibility, they are still not enough to create an environment which arranges safety and autonomy for the visual impaired people and the other ones who attend there. This study suggests that it happened because the engineering interventions at the Campus have been based on Brazilian technical standards NBR 9050:2004, which is proper for the physical impaired people, but it does not offer enough information to respond to all the specific needs demanded by all the classifications of visual impairment.

Análise do uso do Portal de Periódicos da CAPES na perspectiva de mestres e doutores formados pelo Programa de Pós-graduação em Administração da UFRN

The Brazilian CAPES Journal Portal aims to provide Information in Science and Technology (IST) for academic users. Thus, it is considered a relevant instrument for post-graduation dynamics and the country´s Science and Technology (S&T) development. Despite its importance, there are still few studies that focus on the policy analysis and efficiency of these resources. This research aims to fill in this gap once it proposes an analysis of the use of the CAPES Journal Portal done on behalf of the master´s and doctoral alumni of the Post Graduate Program in Management (PPGA) at the Federal University of Rio Grande do Norte (UFRN). The operationalization of the research´s main objective was possible through the specific objectives: characterize graduate profile as CAPES Journal Portal users b) identify motivation for the use of CAPES Journal Portal c) detect graduate satisfaction degree in information seeking done at CAPES Journal Portal d) verify graduate satisfaction regarding the use of the CAPES Journal Portal e) verify the use of the information that is obtained by graduates in the development of their academic activities. The research is of descriptive nature employing a mixed methodological strategy in which quantitative approach predominates. Data collection was done through a web survey questionnaire. Quantitative data analysis was made possible through the use of a statistical method. As for qualitative analysis, there was use of the Brenda Dervin´s sense-making approach as well as content analysis in open ended questions. The research samples were composed by 90 graduate students who had defended their dissertation/thesis in the PPGA program at UFRN in the time span of 2010-2013. This represented by 88% of this population. As for user profile, the analysis has made evident that there are no quantitative differences related to gender. There is predominance of male graduates that were aged 26 to 30 years old. As for female graduates, the great majority were 31 o 35 years old. Most graduates had Master´s degree scholarship in order to support their study. It was also seen that the great majority claim to use the Portal during their post graduation studies. The main reasons responsible for non use was: preference for the use of other data bases and lack of knowledge regarding the Portal. It was observed that the most used information resources were theses and dissertations. Data also indicate preference for complete text. Those who have used the Portal also claimed to have used other electronic information fonts in order to fulfill their information needs. The information fonts that were researched outside in the Portal were monographs, dissertations and thesis. Scielo was the most used information font. Results reveal that access and use of the Portal has been done in a regular manner during post graduation studies. But on the other hand, graduates also make use of other electronic information fonts in order to meet their information needs. The study also confirmed the important mission performed by the Portal regarding Brazilian scientific communication production. This was seen even though users have reported the need for improvement in some aspects such as: periodic training in order to promote, encourage and teach more effective use of the portal; investment aiming the expansion of Social Sciences Collection in the Portal as well as the need to implement continuous evaluation process related to user satisfaction in regarding the services provided.

Junho de 2013: o mês que não começou

This work aimed to analyze the so called June Journeys which happened in Brazil in 2013, in an effort to establish a proper ontology for cyberspace that goes beyond old dichotomies that put men and techniques in polar opposites, making difficult to perform a constructive – and not merely pessimist – analysis of the crossroads between politics and technology. This analysis uses as basis and methodological guidance the Theory of Actor-Network (ANT or TAR) widely used in social studies of science and technology to overcome these dichotomies and allow the analysis of networks, so that is clear the political instability that arises in this context which profoundly changes the political game.

Desenvolvimento de uma técnica para análise de desgaste em peças metálicas com o uso do ciclotron CV-28 do IEN

As técnicas nucleares, com ênfase a técnica conhecida como TLA - Thin Layer Activation, tem sido utilizada com sucesso e contribuído significativamente para o estudo de sistemas tribológicos, na análise e medição de desgaste para profundidades na ordem de grandeza de 10 µm apesar potencialmente poder aplicadas a espessuras de dezenas de milímetros. Esta limitação é intrínseca da técnica utilizada na ativação da camada superficial da peça ou elemento a ser investigado, que consiste na aplicação direta de um feixe de partículas carregadas a uma determinada energia, equivalente a máxima seção de choque do material a fim de obter uma taxa ativação constante ao longo de uma determinada espessura ou utilizando uma energia menor que este valor para se obter uma taxa ativação linear também para uma determinada profundidade de ativação. O objetivo desse trabalho é apresentar uma nova técnica que consiste na utilização de um feixe de energia superior a energia correspondente à máxima seção de choque e aplicar um elemento degradador (Roda Degradadora) como objetivo de homogeneizar a ativação superficial ao longo da espessura da amostra, possibilitando uma melhoria na precisão da análise e possibilitando ainda um maior alcance dessa camada e aumentando a gama de aplicações possíveis dessa técnica, onde por exemplo, maiores taxas de desgaste possam ser analisadas. Após o experimento e análise dos dados constatou-se que a técnica proposta melhora a linearidade da curva que representa a taxa de ativação e aumentando significativamente a profundidade analisável podendo chegar a ordem 6 x 10 µm. Em adição este trabalho reinaugura a pesquisa em aplicações nucleares no IEN - Instituto de Engenharia Nuclear com utilização de aceleradores de partículas tipo ciclotron.

Projeto e desenvolvimento de um sistema de irradiação multipropósito com diagnóstico de feixes para o acelerador de partículas cíclotron CV 28

O projeto e desenvolvimento de uma nova linha de feixe dotada de um sistema que viabilize a irradiação no Cíclotron CV-28 do Instituto de Engenharia Nuclear de alvos extensos e de geometria variável tornaram-se necessário para a realização de estudos e desenvolvimento de aplicações de técnicas nucleares e análises de materiais por ativação em condições de irradiação até então não disponíveis. Este sistema que poderá ser utilizado em irradiações com feixes de prótons, alfas, deutério e hélions (He3) a energias variáveis, é composto por dispositivos de: proteção, interceptação, colimação e medição da intensidade do feixe, de forma a possibilitar a realização de irradiações em condições controláveis e reprodutíveis. Para tanto, peças em alumínio e PVC-foram usinadas de forma a construir os componentes do sistema, notadamente colimadores com 13mm e 9mm de diâmetro, um dispositivo de colimação de quatro setores, um "beam stop", duas flanges de isolamento elétrico e um porta alvo (com janela degradadora). Identificou-se também a necessidade de se dotar o sistema aqui desenvolvido de um circuito de refrigeração próprio à água deionizada que é responsável pela refrigeração de todos os seus componentes que possam ter contato com o feixe. O sistema conta ainda com conexões para vácuo, que possibilitam fazer um pré-vácuo em sua câmara de irradiação, de forma que a mesma possa interligada a linha de transporte de feixe de Cíclotron CV-28, sem causar danos ao vácuo do mesmo. A condição para se fazer esta interligação é a obtenção de um pré-vácuo no ordem de 10-4 torr. Os resultados experimentais obtidos com a realização de irradiações de alvos metálicos especialmente desenvolvidos para testar o sistema, que é tema da presente dissertação, atestam a confiabilidade e reprodutibilidade das condições de irradiação, o que viabilizam o desenvolvimento e emprego de novas unidades de irradiação a serem incorporadas ao mesmo. Esse sistema de irradiação já está sendo utilizado na linha 2 do CV-28

Redes de conversação como possibilidade de formação do professor tutor virtual na mediação pedagógica da educação profissional a distância

A educação a distância apoiada pelos meios de comunicação digital ampliou as possibilidades de interação, flexibilizando o processo de mediação pedagógica no tempo e no espaço. Nessa perspectiva, a educação profissional democratizou seu acesso, na qual os conhecimentos de nível técnico são customizados em um Ambiente Virtual de Aprendizagem (AVA) para serem mediados a distância. Esta tese, apresentada na forma de artigos, problematiza o processo de mediação pedagógica realizado pelo professor tutor virtual na Rede e-Tec Brasil do Instituto Federal de Educação, Ciência e Tecnologia Sul-rio-grandense (IFSul) Campus Visconde da Graça (CAVG). Nesse modelo de ensino, o professor tutor virtual é contratado para atuar, pelo período de dois anos, em todas as disciplinas curriculares de um curso técnico. Se, por um lado, isso permite-lhe conhecer a realidade de seus alunos; por outro, exige-lhe um esforço pedagógico de apropriação e mediação dos conteúdos específicos nas diversas disciplinas que integram os currículos de cada curso. A pesquisa buscou conhecer como o professor tutor virtual apropria-se dos conhecimentos específicos nos cursos técnicos para mediá-los pedagogicamente com os alunos. Apresentamos, como hipótese explicativa neste estudo, que é na convivência com o professor pesquisador que o professor tutor virtual encontra a possibilidade de se apropriar dos conhecimentos curriculares para poder mediá-los pedagogicamente com os alunos. Para sustentar teoricamente nossas proposições na experiência vivida, estabelecemos uma rede de conversação com os autores Humberto Maturana, Pierre Lévy, Lee Shulman e Maurice Tardif, por meio dos conceitos: cultura em redes de conversação; inteligência coletiva; conhecimento pedagógico do conteúdo; e formação profissional docente. Como procedimento metodológico, encontramos na técnica do Discurso do Sujeito Coletivo (DSC), de Lefèvre e Lefèvre, uma estratégia de abordagem qualitativa para analisar as recorrências encontradas nos discursos dos professores tutores virtuais. O estudo aponta que uma rede de conversação recursiva entre o professor pesquisador e o professor tutor virtual possibilita a apropriação de conhecimentos técnicos e específicos necessários ao processo de mediação pedagógica com os estudantes. Essa convivência, no caminho da constituição de um coletivo inteligente, favorece o trabalho colaborativo no ambiente da tutoria, contribuindo para profissionalizar o processo de mediação pedagógica na educação profissional a distância do IFSul CAVG. Supported by digital media, distance learning has increased the possibilities of interaction, easing the process of pedagogical mediation in time and space. From this perspective, the access to professional education has been democratized: technical knowledge is customized in a Learning Managing System and later delivered by means of mediated distance education courses. Structured in a sequence of articles, this dissertation addresses the problem of the pedagogical mediation process performed by on-line tutor teachers at Rede e-Tec Brasil of the Instituto Federal Sul- rio-grandense (IF-Sul), Campus Visconde da Graça (CAVG). This model of education establishes that on-line tutor teachers are hired to work with all the curriculum courses of a technical program for two years. If, on the hand, it allows these teachers to know the reality of their students well, on the other hand it demands them a pedagogical effort of appropriation and mediation of the specific contents guiding the various courses that comprise the curriculum of each program. This research aimed to find out how on-line tutor teachers appropriate expertise from technical programs to mediate it with their students in a pedagogical way. The explanatory hypothesis given is that by working together and sharing experience with the teacher/researcher, on-line tutor teachers will be able to appropriate of curricular knowledge and pedagogically mediate it with their students afterwards. To support our theoretical propositions, a network of conversation was established with authors like Humberto Maturana, Pierre Lévy, Lee Shulman, and Maurice Tardif through the concepts of culture in networks of conversation, collective intelligence, pedagogical content knowledge, and teacher training. As a methodological procedure, the technique of the Collective Subject Discourse (CSD), by Lefèvre and Lefèvre, was found to offer a strategy of qualitative approach to analyze the recurrences seen in the speech of on-line tutor teachers. The study shows that a recursive network of conversation between the teacher/researcher and the on-line tutor teacher enables the appropriation of specific and technical knowledge required for the process of pedagogical mediation with students. The experience of sharing a consensual professional relationship, in which one respects and accepts the other as a way of establishing a collective intelligence, encourages collaborative work in the tutoring environment, helping professionalize the process of pedagogical mediation in distance professional education at IFSul CAVG.

O ensino da estatística nos anos finais do ensino fundamental

Result of a professional master course of research work in Teaching Science and Technology of the Federal Technological University of Paraná (UTFPR), this work aims to provide the mathematics teacher of the final years of elementary school a teaching sequence (SE) which includes basic content of Statistics provided in the curriculum. In this book a text about the importance of the teaching of statistics is presented, as well as issues related to literacy skills, reasoning and statistical thinking. The development of the SE was designed considering the presuppositions of contextualization, being structured in six steps. We chose to develop a work with the basic contents of Statistics through real data collected with the participation of students, within a context for them significant. This option was due to be possible to develop with the students situations such as: raising hypotheses , communication situations experienced by different graphs and tables , results of discussion and understanding of the significance of the results obtained by means of statistical calculations. Thus, it is believed to be possible to contribute to the development of statistical skills by the students.

Telefone celular como recurso didático no ensino de física

Currently, there are several factors that suggest the need for the school to review their teaching practices: 1) the speed with which information and communication technologies - ICT are spread throughout society and in particular the increasing use of mobile phone by groups in school age;2) the scope and power of integrating ICT convergence of these technological resources, that can be used as teaching resources; 3) the fact that nowadays students grow up in a technological world and make their thought patterns operating in accordance with this reality, etc... In contrast, there are educators unrelated to the appropriation of ICT, presenting, in many cases, resistance to them. There is a incongruity between how individuals use mobile phones, for example, inside and outside the school. There are also educators, schools, public educational departments claiming to be against mobile phones usage; bills and laws regulating their use in educational space, etc... For these controversial aspects we have investigated whether cell phone use as a teaching resource practices mediator in Physics teaching. For this purpose, we developed an applied research with qualitative and exploratory approach about the objectives, adopting participant and the technical procedures. A documental and bibliographical research was taken. First of all, data were collected by e-mail, through a multiple choice questionnaire applied to private school teachers in southern Brazil, to identify the researched reality and develop teaching practices likely to be applied in the studied corpus. Then, such practices were applied in workshops located in Curitiba and Ponta Grossa cities, in Paraná state. During the application, data was collected by the researcher's field notes. Then, we recorded chats about the workshops from an instant message software (msn messenger), and we took photographic records. Data analysis was performed by triangulation. The results showed the need to enhance continuing education courses for teachers and the production of national academic literature, such as articles, dissertations, theses and books that explore the theme of the cell phone and its functionality in educational spaces as an educational resource mediator in the practices of teaching Physics. They are available in the dissertation defended in 2012, and now are also systematized in this book, organized as a final product of research conducted by the Graduate Program in Science Education and Technology UTFPR, Campus Ponta Grossa-PR.

Transparência das informações públicas nos portais das instituições federais de educação profissional da região sul do Brasil

Considering the need of communication between public management and society and its citizens, in a way which is more effective and transparent, the aim of this research was to analyze the transparency of public information presented by the managers of the portals of southern Brazil’s Federal Institutes. It is a qualitative and quantitative research, applied as its purpose, and exploratory as its aim. In order to explain the issue from the theoretical frameworks published, it will be used as a procedure the bibliographic research and the further study field research in the six southern Brazil’s Federal Institutes. Therefore, the theoretical framework approaches aspects about public transparency, concepts of information and communication in the public sector, and it presents measurement indexes of public transparency. The data collection with the Institutes sought to measure – in the portals – the level of transparency of the information presented by the managers, applying a search tool which provided the transparency index of eleven categories of the researched items, besides verifying the presence of the required items by Access to Information Law. In the sequence, it sought to verify the Institutes managers’ perception of the aspects which composes the proposed theme, for the purpose of observing how the process of communication between public agencies and the citizen is happening. The main results obtained emphasize, in a general way, a low level of public information propagation, with a lower average of propagation to the information about social, environmental and economic responsibility, and a greater average to the information related to the institution’s general data – from its management structure to its ordinance. It was also observed that no institution which was researched fully comply with the demands of the Access of Information Law. The results about the manager perceptio demonstrate a tendency in publishing the produced information, however, elements such disorganization of information in the portals, lack of standardization of the virtual structure and type of language to use, and lack of procedures of popular participation and interaction in the portals are determiners to bring problems in the access and in the communication with the public. Besides, the short time of institutions’ creation and the short time of the managers assuming their functions must be considered as a reflex of the found results. Therewith, the present study highlighted the importance of Public Transparency theme and it reached a positive result to a scientific and social contribution.

Glossário de ciência aberta

O conhecimento é um bem público, pertença de todos e que a todos deve beneficiar e ser concedido. A sociedade e as comunidades de investigação associadas à produção e à curadoria do conhecimento devem assumir um papel responsável e fundamental na sua promoção, valorização, divulgação e partilha. Nos casos em que a investigação é realizada com recurso a financiamento público, este papel é reforçado em consequência da obrigatoriedade da sua divulgação e disponibilização. Por outro lado, a ciência tem um caráter público, porque o conhecimento é de todos e para todos. O conceito de Ciência Aberta tem ganho destaque e assumido uma posição sólida na sociedade no seguimento das políticas desenvolvidas por agências públicas de financiamento de I&D de vários países, das recomendações da Comissão Europeia e das iniciativas levadas a cabo em Portugal, ao nível das instituições de ensino superior, da Fundação para a Ciência e Tecnologia e da tutela (Ministério da Ciência, Tecnologia e do Ensino Superior). A promoção do conceito «Conhecimento Para Todos» e, por arrastamento, os pressupostos da Ciência Aberta, tendem a reforçar o impacto social da investigação, reconhecendo-a e valorizando-a. A Ciência Aberta é, assim, um modelo de prática científica mais abrangente, uma vez que acontece em todas as etapas da investigação e possibilita o acesso aberto a publicações, dados de investigação e inclui a interoperabilidade da infraestrutura científica, as metodologias partilhadas e possibilita a utilização de ferramentas para data mining. A Ciência Aberta contribui para a melhoria da qualidade da ciência, permitindo o aumento das colaborações que envolvem a investigação e a sociedade em geral e um maior impacto socioeconómico da pesquisa pública. No âmbito da efetiva implementação da Ciência Aberta em Portugal, a Secretaria de Estado da Ciência e do Ensino Superior desenvolveu um conjunto de iniciativas, de entre as quais a divulgação e a formação assumem especial relevância. Nesse âmbito surgiu a proposta da construção de um glossário da Ciência Aberta. O convite foi endereçado a duas bibliotecárias de instituições do ensino superior universitário e politécnico. O presente estudo apresenta o projeto e o trabalho desenvolvido entre maio e setembro de 2016. Foram compiladas 166 designações com entradas pelo idioma português, preferencialmente, seguidas da respetiva expressão inglesa; privilegiou-se a entrada no idioma inglês sempre que a expressão portuguesa resultava em completo desconhecimento para o leitor/investigador. O Glossário de Ciência Aberta, disponível em http://www.ciencia-aberta.pt/glossario, segue os princípios da transparência, do acesso aberto, da reutilização da informação e do uso de ferramentas web. As definições apresentadas são da responsabilidade de inúmeras entidades oficiais e científicas, identificadas com um link direcionado à informação original. Na recolha de informação foram privilegiados os conteúdos em formato digital. São apresentadas relações de associação entre expressões e salvaguarda-se, sempre que possível, a expressão original. Este é um projeto work-in-progress, pelo que são bem-vindos mais e novos conteúdos através do email ciência-aberta@mctes.gov.pt.
