This reality, expanded to the virtual world, which allows communication without borders through the Internet between people anywhere in the world. Thus, this dissertation aims to analyze quantitatively the relationships among Twitter users, through the use of Social Media monitoring tools combined with the techniques of Social Network Analysis, aiming to define the profile relationship of individuals within the scenario of which the same is inserted either in education or credit. Studies show that by applying the metrics degree of centrality, brokerage and centrality centrality proximity is possible to define the profile of collaborative people in a particular group, and any flaws in the dissemination of information on the same. It should be noted also, that this research presents a way to define participation and affinity of people in a given context. The results show that it is possible to correlate the data of users on Twitter, with their indices regarding the application of the metrics data with social network analysis and credit companies in order to quantitatively analyze the relationship of these users on various aspects rated the credit crunch. / Sob o aspecto de seres sociais, os seres humanos procuram incessantemente interagir uns com os outros, nas mais variadas ocasiões. Realidade esta, expandida ao mundo virtual, ao qual permite uma comunicação sem fronteiras através da Internet entre as pessoas de qualquer parte do mundo. Desta maneira, a presente dissertação visa analisar quantitativamente os relacionamentos entre usuários do Twitter, através da utilização de ferramentas de monitoramento de Redes Sociais aliados à técnicas de Análise de Rede Sociais, objetivando definir o perfil de relacionamento dos indivíduos dentro do cenário ao qual o mesmo encontra-se inserido quer na área de educação ou crédito. Os estudos realizados revelam que através da aplicação das métricas grau de centralidade, centralidade de intermediação e centralidade de proximidade é possível definir o perfil colaborativo das pessoas dentro de um determinado grupo e eventuais falhas na disseminação de informações no mesmo. Salienta-se também, que a referida pesquisa apresenta uma forma de definir a participação e a afinidade de pessoas em um determinado contexto. Os resultados obtidos mostram que é possível correlacionar os dados dos usuários no Twitter, com seus índices referente a aplicação das métricas de análise de redes sociais e com dados de empresas de crédito, a fim de analisar quantitativamente o relacionamento destes usuários em diversos aspectos votados à restrição de crédito.

O presente estudo desenvolveu-se na perspectiva de entrelaçar as pesquisas em Interação Humano- Computador – IHC com a Epistemologia Genética de Jean Piaget, visando delinear possíveis intersecções entre esses dois domínios no contexto de uma investigação prática. O Para tanto, esta dissertação, elegeu o desenvolvimento de um chat com uma interface 3D isométrica, destinado à crianças em processo de alfabetização, denominado Cooperativa do Conhecimento, como um problema interessante em IHC e, que podería ser investigado sob a perspectiva da teoria piagetiana. O estudo baseou-se na investigação dos processos cognitivos dos sujeitos em interação tanto com a Cooperativa do Conhecimento, quanto com o chat de interface tradicional. Foram realizados um total de 18 experimentos, cada um consistindo de uma sessão de chat, envolvendo, no total, 32 crianças do ensino fundamental. A análise dos dados foi desenvolvida considerando a evolução do processo de construção dos necessários, pelas crianças, em relação a interface dos softwares. Como resultado, foram elaboradas duas microgêneses da conceituação das atividades e dos mecanismos funcionais da Cooperativa do Conhecimento e do chat tradicional. Os resultados indicam que a proposta de interface para a Cooperativa do Conhecimento, elaborada neste estudo, favorece o desenvolvimento do processo de conceituação, tanto das atividades quanto dos mecanismos funcionais, ocasionando, que, os sujeitos consigam, muito mais cedo, estabelecerem a conversão como um possível dentro do ambiente, bem como, compreender as relações necessárias para tal ação. / The present study was developed with the goal of braiding the research in Human Computer Interaction – HCI with the Genetic Epistemology of Jean Piaget, in order to outline possible intersections between these theories in the context of a practical investigation. T For this purpose, this thesis, elected the development of a chat tool, with an isometric 3D interface, for children in the acquisition process of written language, named Cooperativa do Conhecimento, as an interesting problem in the field of HCI, that could be investigated with the piagetian theory. The study was based in the investigation of the child's cognitives process while in interaction with Cooperativa do Conhecimento and with a traditional chat. It was made a total of 18 experiments, each one consisting of a chat session, in a total of 32 primary school children. The results indicate that the interface proposal for Cooperativa do Conhecimento, developed in this study, fostered the development of the conceituation process, making, that the children stabilished the conversation as a possibility inside this environment earlier than in the traditional chat and understanded the necessary relations for this action.

Some of the questions which directed this study development are: how does the public teachers formation for the use of the TICs developed by NTE-Goiânia multipliers teachers happen? The courses offered by NTE Goiânia are based in which conceptions? Do the courses offer anything besides technical training? To answer these and other questions which appeared during the research, the Study of case was used in a historical dialectical perspective. In order to have a theoretical base we searched the contribution of Barreto (2001; 2004 and 2006), Belloni (2001; 2005), Castells (1996), Cysneiros (1999; 2000 and 2001), Dupas (2003 and 2000), Frigotto (1996, 2001), Kenski (2001; 2003), Pretto (2001; 2002 and 2006), Santos (2003), Silveira (2001), Souza (2004; 2006) and Toschi (2001). Thus, looking forward to reach the aims of the research and following the methodology chosen, I did the observation and analysis of the routine of the NTE and its professionals; collected and analysed documents related to the NTE and PROINFO; interviewed the multipliers teachers; followed up, reported and analysed a course offered by the NTE and coordinated by a multiplier teacher, in the semi- attended modality, among other activities related to the research and to the Study of Case. The research conclusion points to a short and in service formation, in the patterns proposed by the international organizations to finance the Brazilian Education; a contrast between a poor praxis and a modernization speech adopted by the state government concerning education; the adoption of semi-attended and in service courses to cheaper the formation and at last, the difficulties that the NTE Goiânia have had to insert the TICS in a critical and creative way in the public schools of Goiânia. / Este estudo, dentro da linha de pesquisa de formação e profissionalização docente, do Programa de Pós-Graduação da Faculdade de Educação da Universidade Federal de Goiás, teve como objetivos investigar a qualidade do processo formativo dos professores multiplicadores do Núcleo de Tecnologia Educacional de Goiânia, no que diz respeito ao referencial crítico-reflexivo para o uso das Tecnologias da Informação e Comunicação e analisar as condições reais em que se dá esta formação. Para o desenvolvimento deste estudo, algumas questões serviram como norte, entre elas destacam-se: como se dá a formação dos professores da rede pública de ensino para o uso das tecnologias da informação e comunicação desenvolvida pelos professores multiplicadores, que atuam no Núcleo de Tecnologia Educacional de Goiânia? Quais são as concepções de formação de professores que dão embasamento aos cursos promovidos pelo NTE? Estes cursos vão além do treinamento técnico? Utilizando o Estudo de Caso , dentro de uma perspectiva histórico-dialética, procuramos responder a estas questões e a outras que foram surgindo no decorrer da pesquisa. Para subsidiar teoricamente nosso trabalho, buscamos a contribuição de Barreto (2001; 2004 e 2006), Belloni (2001; 2005), Castells (1996), Cysneiros (1999; 2000 e 2001), Dupas (2003 e 2000), Frigotto (1996; 2001), Kenski (2001; 2003), Pretto (2001; 2002 e 2006), Santos (2003), Silveira (2001), Souza (2004; 2006) e Toschi (2001). Para contemplar os objetivos da pesquisa, dentro da opção metodológica escolhida, fiz a observação e análise do cotidiano do NTE e de seus profissionais; recolhi e analisei documentos referentes ao PROINFO e ao NTE; entrevistei professores multiplicadores; acompanhei, relatei e analisei um curso oferecido pelo Núcleo e coordenado por uma professora multiplicadora, na modalidade semipresencial, entre outras atividades referentes à pesquisa e ao Estudo de Caso. A conclusão da pesquisa aponta para uma formação aligeirada e em serviço, nos moldes propostos pelos organismos internacionais de financiamento da educação no Brasil; uma prática precária em contraste com um discurso de modernização adotado pelo Governo do Estado no que se refere à educação; a adoção de cursos semipresenciais e em serviço no sentido de baratear a formação e, por fim, as dificuldades enfrentadas pelo NTE de Goiânia para inserir de forma crítica e criativa as Tecnologias da Informação e da Comunicação nas escolas públicas de Goiânia.

The problem addressed in this thesis was identified in a real life context in which an attempt was made to re-constitute a BSc Computer Science degree programme. The curriculum was modelled on the ACM/IEEE Computing Curriculum of 2001. It was further required to comply with accreditation requirements as defined by ABET’s Computing Accreditation Commission. Relying on a spreadsheet, the curriculum was iteratively and manually evaluated against the ACM/IEEE curriculum specification. A need was identified to automate or at least semi-automate this process. In this thesis a generalisation of the problem is presented. Curricula are modelled as directed graphs (digraphs) in which graph vertices represent curriculum elements such as topics, knowledge areas, knowledge units year- levels or modules. Edges in the graph represent dependencies between these vertices such as belonging to grouping or pre-requisites. The task of curriculum comparison then abstracts to a task of digraph comparison. A framework, the Graph Comparison Framework, is proposed. The frame- work comprises of components which are used to guide the digraph comparison process. The so-called Graph Trans-morphism algorithm component is the only component in the framework which is mandatory. The algorithm converts the information from one of the digraphs being compared into the structure of the other. This conversion enables the graphs to be compared as graph isomorphisms. All digraphs are modelled as sets of triples, making it possible to subtract one digraph from another using the set minus operator. The resultant difference sets are used by components defined in the framework to quantify and visualise the differences. By modelling curricula as digraphs and applying the framework to the di-graphs, it is possible to compare curricula. This application of the framework to a real-world problem forms the applications research part of the thesis. In this part, domain knowledge of curriculum design is necessary to apply to the curriculum being developed in order to improve it. / Thesis (PhD)--University of Pretoria, 2014. / Computer Science / unrestricted

Computers are excellent tools and assistants in foundation-phase classrooms. Computer-assisted instruction (CAI) influences the way teachers teach, as well as the way learners learn with regard to the curriculum. The responsibility for providing foundation phase-learners with educationally appropriate computer experiences in literacy, numeracy and life skills rests with the educators because the learners' progress in learning depends on the skills, attitudes and ingenuity of the educators, and the software they select for the learners. Educators should have the vision, the knowledge and the experience to introduce and apply CAI to benefit every learner in the didactic situation. Educators' general lack of knowledge and skills in this area has necessitated the compilation of didactic guidelines. The guidelines emerged from the literature that was consulted for this study. These guidelines should assist educators in providing successful CAI for learners. / Educational Studies / M.Ed.

Several technologies and languages exist for the development and implementation of distributed systems. Furthermore, several models for teaching computer programming and teaching programming in a distance-based educational environment exist. Limited literature, however, is available on models for teaching distributed computing in a distance-based educational environment. The focus of this study is to examine how distributed computing should be taught in a distance-based educational environment so as to ensure effective and quality learning for students. The required effectiveness and quality should be comparable to those for students exposed to laboratories, as commonly found in residential universities. This leads to an investigation of the factors that contribute to the success of teaching distributed computing and how these factors can be integrated into a distance-based teaching model. The study consisted of a literature study, followed by a comparative study of available tools to aid in the learning and teaching of distributed computing in a distance-based educational environment. A model to accomplish this teaching and learning is then proposed and implemented. The findings of the study highlight the requirements and challenges that a student of distributed computing in a distance-based educational environment faces and emphasises how the proposed model can address these challenges. This study employed qualitative research, as opposed to quantitative research, as qualitative research methods are designed to help researchers to understand people and the social and cultural contexts within which they live. The research methods employed are design research, since an artefact is created, and a case study, since “how” and “why” questions need to be answered. Data collection was done through a survey. Each method was evaluated via its own well-established evaluation methods, since evaluation is a crucial component of the research process. / Computing / M. Sc. (Computer Science)

The study started with those theories that explain inclusion and exclusion. Digital exclusion (or digital divide), a set of interdictions that block the access of individuals to modern resources of digital communication, was found inside the social exclusion, and was studied so. The research on the subject regarding Brazil was performed preliminarily with some of the few works that were found on the theme, and then with the help of data surveys of IBGE on the possession of microcomputers, telephone lines and the availability of internet access, regarding not only individuals but households as well. Among our conclusions, we should remark these: 1) Brazil is needing more studies on this subject, since we found a good number of research on digital bridging in other languages and based on other countries but just a few in portuguese and regarding Brazil; 2) The main digital bridging actions have been done without any further assessment, what means that its results remain unknown; thus, it is impossible to tell if the knowledge acquired during these actions changes culture and behavior of an individual, turning him into an included in the digital communication world / Este estudo procurou investigar, dentro da literatura contemporânea disponível, a inclusão digital em geral, e especificamente as possibilidades de acesso dos brasileiros às novas tecnologias de comunicação a existência da possibilidade de acesso classifica o indivíduo como um incluído digital. O trabalho foi iniciado tomando por base as teorias que explicam inclusão e exclusão, percorrendo depois teorias e pesquisas relacionadas à exclusão social. A exclusão digital, um conjunto de interdições que impedem o acesso de indivíduos aos modernos recursos de comunicação digital, foi localizada dentro da exclusão social e assim estudada. A pesquisa sobre o assunto em relação ao Brasil foi feita preliminarmente a partir das poucas obras que tratam desse tema, e depois com o auxílio de dados de levantamentos do IBGE relativos à posse de microcomputadores, telefones e disponibilidade de acesso à Internet, referentes não só a indivíduos como também a domicílios. Entre as conclusões, devemos ressaltar as de que: 1) o Brasil está necessitando de estudos mais aprofundados sobre o assunto, já que localizamos boa quantidade de pesquisas sobre a Inclusão Digital em outras línguas e sobre outros países mas poucas em português e sobre essa questão no Brasil; 2) as grandes ações de inclusão digital estão sendo feitas sem acompanhamento posterior, ou seja, os resultados não são conhecidos, não sendo possível, portanto, concluir se o conhecimento adquirido nessas ações transforma a cultura e o comportamento do indivíduo, a ponto de torná-lo de fato um incluído no mundo da comunicação digital

Com o intuito de disponibilizar objetos educacionais (OE) para o professor, o Ministério da Educação (MEC) tem desenvolvido uma série de iniciativas para disseminação de OE, como a Rede Interativa Virtual de Aprendizagem (RIVED), o Portal do Professor e o Banco Internacional de Objetos Educacionais (BIOE). Além disso, o MEC possui outras iniciativas no sentido de divulgar e tornar acessíveis essas tecnologias na escola, como o E-PROINFO e o Programa Um Computador por Aluno (UCA). Por intermédio de um estudo de caso, de uma escola pública, foi investigado como os professores selecionam objetos educacionais digitais em contextos educacionais no âmbito do projeto UCA. Escolhemos como abordagem metodológica a pesquisa ação e, como estratégia de pesquisa, o estudo de caso, no qual nos utilizamos de técnicas como: entrevista semiestruturada, observação participante e questionário via e-mail. A pesquisa foi realizada com professores participantes de uma escola de Fortaleza contemplada com laptops do Projeto UCA. A partir desse trabalho, esclarecemos como os professores selecionaram os objetos educacionais e quais os critérios utilizados por eles para a escolha dos recursos. Respondemos também, quais as dificuldades encontradas por esses professores na ocasião da seleção dos objetos educacionais. Sobre os critérios de busca dos objetos, percebemos que a maioria dos professores prefere o que é mais atrativo (100%). Quanto à localização, a maioria das professoras tem uma metodologia de pesquisa orientada por temas, interesses pedagógicos e utilizava os motores de busca, e não os portais sugeridos pelo curso de formação. Além disso, nenhuma professora sabia da existência do BIOE, ferramenta apresentada na intervenção, o que demonstra que existe uma má disseminação das ferramentas desenvolvidas pelo Ministério da Educação.
