Formação de professores, saberes, reflexividade e apropriação da cultura digital no Projeto Um Computador por Aluno (UCA)

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

Um sistema inteligente de classificação de sinais de EEG para Interface Cérebro-Computador

The Brain-Computer Interfaces (BCI) have as main purpose to establish a communication path with the central nervous system (CNS) independently from the standard pathway (nervous, muscles), aiming to control a device. The main objective of the current research is to develop an off-line BCI that separates the different EEG patterns resulting from strictly mental tasks performed by an experimental subject, comparing the effectiveness of different signal-preprocessing approaches. We also tested different classification approaches: all versus all, one versus one and a hierarchic classification approach. No preprocessing techniques were found able to improve the system performance. Furthermore, the hierarchic approach proved to be capable to produce results above the expected by literature

Relacionamentos humanos mediados pelo computador: as experiências de intermautas cadastros no site de comunidades UOL K

Os sites de comunidades têm atraído grande número de pessoas. Elas passam a se relacionar à distância, utilizando para isso recursos como envio de recados e mensagens e trocam informações sobre si através da auto-descrição (perfil) e do uso de imagens, ambos abertos ao público. A experiência de possuir uma página pessoal neste tipo de ambiente e se relacionar com pessoas através dela se constitui o objeto desta pesquisa a qual foi realizada com base na metodologia qualitativa. Foram entrevistados 16 usuários da rede de relacionamentos UOL K, pertencente ao UOL (Universo OnLine), considerado o principal portal de conteúdo e provedor pago de acesso à Internet do Brasil. A análise dos resultados destacou os seguintes aspectos: o site possibilita tanto fazer novos contatos quanto manter contatos feitos anteriormente, há uma tendência a fazer novos contatos, a língua escrita é utilizada tanto para se comunicar como para refletir acerca de si mesmo, o anonimato é favorecido pela comunicação à distância e causa receio de se decepcionar com o outro, as experiências são vistas como reais mesmo ocorrendo num ambiente virtual, “estar online” pode ser prazeroso e não significa desprender-se do mundo offline, a afiliação às comunidades é freqüente e tem como base objetivos comuns, o uso da foto é, graças aos recursos do site, um elo entre a comunicação sincrônica (bate-papo) e a comunicação assincrônica (UOL K), há uma ênfase na sexualidade e, por fim, os usuários se vêem na necessidade constante de rever e relativizar conceitos como próximo e distante, público e privado, estar ou não online. Conclui-se que, mesmo não tendo o hábito de marcar encontros face a face, os usuários são capazes de se relacionar virtualmente de forma genuína, trocar afetos, formar vínculos e manter uma vida online na qual o comunicar-se encontra seu sentido em si mesmo, podendo não haver outro objetivo a não ser o de estar em contato.

Tecnologias de Informação e Comunicação no cotidiano dos adolescentes: enfoque no comportamento e na competências informacionais da geração Google

Introduction: Individuals born from the 1990’s to accompany technological change course and learn how to use the technological resources that have access before they even learn to read or write. In this sense, the literature considers the digital natives or even 'Google generation'. However, it has been questioned their skills to identify information needs and seeking and use of information in the most varied environments digital information available on the Web. Objectives: To characterize the behavior of information seeking in everyday life of a group of teenage students from a private school in Marilia, Sao Paulo. Methodology: A qualitative study with 30 adolescent students of a private school in Marilia, Sao Paulo. Data collection was accomplished at first by means of a questionnaire, based on the research of Hughes-Hussell and August (2007), containing questions about age, gender, hobbies and everyday tasks, and issues the use of computers and the internet, which allowed determination of the social, economic and cultural rights of respondents. Results: have focused on the use of Information and Communication Technologies (ICT) to search access and use information. It was suggested that the "Brotherhood of Informatics', an incentive for students to (re) learn the tools of digital communication and make appropriate use of the resources, products and services on the web to search and effective use of information compatible with their needs and that is tied to the ethical and responsible use of technology environments. Conclusions: The results arising from this study will continue through the continuation of the Confraternity of Computing, which became a "thermometer" on the use of digital information environments and the attitude of the students in front of Information and Communication Technologies in the College “Cristo Rei”.

Avaliação da presença de tecnologias de informação e comunicação no ensino de histologia das universidades de odontologia do estado de São Paulo

In recent decades the rise of the tools of information and communication technology (ICT) has been notorious. Currently ICTs are an important educational tool and is associated with the development of teaching methods courses in basic and higher education. Given the influence that these tools are currently engaged in several sectors, this project aimed to assess the frequency and manifestations of ICT that have been employed in the teaching of histology in the Schools of Dentistry of São Paulo. The virtual page of 43 Higher Education Institutions (HEI) was analyzed to search for links to sites of histology. With this assessment only 4 virtual domains were found which was present a narrow range of virtual tools such as hypertext, graphics, quizzes and lessons in electronic formats. Later, by sending a questionnaire to 46 teachers of histology of the Universities of São Paulo, were analyzed for the presence or absence of a site of discipline, mode and frequency of use of ICTs in education, and the value that teacher attaches to these tools. From the responses obtained were concluded that teachers who have websites in general have no interactivite tools and many seem to ignore the real representation of interactivity in teaching and the possibilities of applications of ICTs. However most teachers recognize the importance of education mediated by virtual tools

Utilização da instrumentação virtual em Labview para criação da interface gráfica do amplificador lock-in utilizado em estudos fisiológicos a partir da comunicação via porta serial

This work presents the development of a graphical interface to the Lock-in Amplifier, which is used in physiological studies on the motility of the gastrointestinal tract in rats and signal processing. With a simple and low cost instrumentation, the resources offered by the virtual interface of LabVIEW software allows the creation of commands similar to the actual instrument that, through communication via standard serial port, transmits data between a PC and peripheral device performing specific and particular needs in the amplifier. Created for the lock-in amplifier model SR830 Stanford Research Systems, the remote manipulation gives the user greater accessibility in the process of configuration and calibration. And, since the software is installed, there is the advantage of eliminating the need of purchase new devices to upgrade the system. The commands created were made to perform six basic modifications that are used in routine of the Biomagnetism Laboratory. The instrumentation developed has the following controls: Amplitude, Frequency, Time Constant, slope low pass filter, sensitivity and offset
