DESENVOLVIMENTO E APLICAÇÃO DE UM MÉTODO PARA DETECÇÃO DE INDÍCIOS DE PLÁGIOPertile, Solange de Lurdes 11 March 2011 (has links)
The distribution and access to information by a much larger number of people on the Internet has grown in a exponential, way has been hard the which control of the originality of the information and facilitating the work of plagiarists users who make use of such information inappropriately. It is in this context that stands the importance of evalute the texts produced in the post-graduate and graduate courses in the classroom and distance modalities, that this paper proposes a new method to detect signs of plagiarism in academic work, which performs to searche similar fragments with web documents. The method developed analyzes the mosaic plagiarism, where the author shares copies of a work by changing only a few words without giving credit to the original work, and the bilingual plagiarism, where the contents of a document in English is translated for Portuguese without reference the original work. In addition, the method was implemented in an integrated tool and to the sending task module of the Moodle platform for access by desktop and by the mobile device aiming to empower the teachers the benefits of its utilization in the posting of work in a AVA, and implemented as a desktop computer system to allow users the access also outside theAVA Moodle. The results showed that the developed method reached satisfactory results in relation to other techniques found in literature, getting over a collection of 14 documents indexs of similarities ranging from 30.07% to 40% and with a precision in the returned results between 71.42 % and 96.15%. The experimental results of a translated document from English to Portuguese had a 100% accuracy in the returned results. / A distribuição e o acesso a informações por um número muito maior de pessoas na internet tem crescido de forma exponencial, o que vem dificultando o controle da originalidade de tais informações e facilitando o trabalho dos usuários plagiadores que fazem uso de tais informações de forma inadequada. Neste contexto que se destaca a importância de avaliar os textos produzidos nos cursos de pós-graduação e graduação, nas modalidades à distância e presenciais, que esta dissertação propõe um novo método para detecção de índicios de plágio em trabalhos acadêmicos, o qual realiza buscas por fragmentos similares com documentos da web. O método desenvolvido analisa o plágio mosaico, onde o autor copia partes de uma obra trocando somente algumas palavras sem dar crédito ao autor da obra original; e o plágio bilíngue, onde o conteúdo de um documento no idioma inglês é traduzido para o idioma português sem fazer referência à obra original. Além disso, o método foi implementado em uma ferramenta e integrada ao módulo de envio de tarefas da plataforma Moodle para acesso via desktop e pelo dispositivo móvel, visando potencializar aos professores os benefícios de sua utilização, já na postagem dos trabalhos no AVA; e implementada como um sistema computacional desktop para permitir aos usuários seu acesso também fora do AVA Moodle. Os resultados obtidos mostram que o método desenvolvido alcançou resultados satisfatórios em relação a outras técnicas encontrados na literatura, obtendo sobre uma coleção de 14 documentos índices de similaridades variando de 30,07% a 40% e com uma precisão nos resultados retornados entre 71,42% e 96,15%. Os resultados do experimento de um documento traduzido do inglês para o português teve uma precisão de 100% nos resultados retornados.

Previous issue date: 2017-03-16 / Sem bolsa / Este estudo objetiva verificar a construção de sentido que emerge a partir das interações frente à proposta de produção de texto mediada por recursos semióticos com o uso das tecnologias digitais móveis. A investigação se deu em uma disciplina de Língua e Literatura III, com 02 hora/aula semanais, nos cursos Técnicos em Informática e Mecatrônica integrados ao Ensino Médio de um Instituto Federal de Educação. Para alcançar o objetivo principal foi desenvolvido um currículo com o intuito de integrar de ações colaborativas por meio de tecnologias digitais móveis com recursos semióticos e para averiguar como os estudantes demostravam a compreensão da escrita literária clássica por meio de recurso semiótico, bem como, relacionar a expressão semiótica apresentada com a leitura que fizeram da obra clássica lida. A fundamentação teórica para a construção desta pesquisa e do currículo proposto foi pautada na revisão teórica sobre as práticas de M-Learning (TRAXLER, 2009; SACCOL, 2010), sobre a colaboração como característica inerente ao ser humano (TOMASELLO, 2003, 2010; PINKER, 2007), no arcabouço ecológico (VAN LIER 2000, 2002, 2004a, 2004b, 2007, 2014; BAKTHIN, 1981) para a construção do currículo intitulado CELL (Currículo Ecológico de Língua e Literatura) pautado no desenvolvimento de consciência, autonomia e autenticidade. A metodologia de pesquisa consistiu na aplicação da proposta do currículo e coleta dos dados obtidos em grupos fechados do Facebook onde os participantes deveriam interagir semanalmente sobre as obras. Os dados foram analisados qualitativamente de acordo com as características do Currículo e da linguagem sobre uma perspectiva ecológica. Os resultados obtidos indicam que é possível integrar as práticas de aprendizagem colaborativa com o uso de tecnologias móveis por meio do currículo desenvolvido. Também identificamos a construção de significado sobre as leituras realizadas nos recursos semióticos trazidos nas postagens dos estudantes. Ainda analisamos em suas interações que a significação dos clássicos lidos se deu pela associação do que leram com as suas vivências e experiências. A facilidade de acesso aos dispositivos móveis e a necessidade de investir nas práticas de letramentos midiáticos representaram fatores importante para a implementação do currículo proposto. Identificamos, porém, que o CELL precisa ser qualificado por meio de investigações que experienciem novas práticas em outros contextos e, apesar de as práticas de avaliação serem evidenciadas nos dados, pensamos que novas propostas possam apresenta-las claramente em uma das etapas. / This study aims to verify the construction of meaning that emerges from the interactions with the proposal of text production mediated by semiotic resources with the use of mobile digital technologies. The investigation took place in Language and Literature III subject, with 02 hour/class per week, in Computer Science and Mechatronics certificate programs integrated to High School in a Federal Institute of Education. To achieve the main objective, a curriculum was developed in order to integrate collaborative actions using mobile digital technologies with semiotic resources as well as to investigate how students demonstrated classical literary writing comprehension through a semiotic resource, and also to relate the semiotic expression presented with the reading that they made of the classic work already read. The theoretical framework of this research and the proposed curriculum is based on theoretical review of M-Learning practices (TRAXLER, 2009; SACCOL, 2010), on collaboration as an inherent characteristic to the human being (TOMASELLO, 1999, 2010; PINKER,2007), in the ecological perspective (VAN LIER 2000, 2002a, 2004b, 2007, 2014; BAKTHIN, 1981; PEIRCE, 1977) for the construction of the curriculum entitled ECLL (Ecological Curriculum of Language and Literature) focused on autonomy, authenticity and awareness. The research methodology consisted in applying the curriculum proposal and collecting data obtained in private groups on Facebook where the participants should interact weekly on the works of art. Data were qualitatively analyzed according to curriculum characteristics and language on an ecological perspective. The results indicate that it is possible to integrate the collaborative learning practices with the use of mobile technologies through the developed curriculum. We also identify meaning construction of the performed readings on the semiotic resources brought in the students' posts. Besides, in their interactions we analyzed that the meaning of the classic readings was based on the association of what they read with their background and experiences. Ease of access to mobile devices and the need to invest in media literacy practices were important factors for implementation of the proposed curriculum. However, we identify that the ECLL needs to be qualified through investigations that experience new practices in other contexts and, although the evaluation practices are evidenced in data, we think that new proposals might clearly present them in one of the stages.

Effect of Internet Environment and Information Literacy on Teaching Will with Wireless Network: An Example of Humanities and Art Education of Junior-High Schools in Kaohsiung CityChen, Mei-yeh 01 February 2009 (has links)
The time for WIMAX (Worldwide Interoperability for Microwave Access) is coming. Wireless network, a major trend of urban development nowadays, has become a part of modern life. In addition, all the countries have put emphasis on the application of information technology in the field of education. Thus, Ministry of Education in Taiwan actively promotes how to integrate information technology into teaching. In order to combine policies with the development of technology industry, building a wireless teaching environment in junior high schools is now a benchmark of becoming a clever mobile city for Kaohsiung City.
As the prosperity of wireless network technology, mobile learning is now the main stream of the ubiquitous society; that is, utilizing modern technology into teaching has become a trend. This research takes the teachers major in humanities and art and the executive directors in the junior high schools in Kaohsiung City as an object of study, probing into the completion of building wireless teaching environments in these schools, the application of wireless network for teaching in the field of humanities and art, and the information literacy in connection with the will to utilize such technology of these teachers.
This research bases on Davis¡¦s Technology Acceptance Model, probing into the usefulness, the ease of use and the will to use of teaching with the wireless network with the construction of the wireless environment in the campus and the information literacy of the teachers by the questionnaires. It adopts SPSS15.0 for Windows as well as Amos 7.0 systems to analyze the data and Structural Equation Modeling to proceed to the causal path analysis of the research structure, testing the causal relationship of each variable in this research. At the same time, it uses the data from the questionnaires and the interviews to mutually confirm the conclusion.
According to this research, there are five conclusions:
1¡BGender, the seniority of teaching, the function of office and the scale of the school will affect the usefulness, the ease of use, the will to use and the information literacy of teaching with the wireless network.
2¡BSo far the construction of wireless environment of the junior high schools in Kaohsiung city is still not perfect; specifically, only few schools can expand wireless access points by themselves while other schools still maintain 5 access points offered by the Education Bureau. Thus, the access points are installed only in the conference rooms or the special-function classrooms; they are insufficient for the normal classrooms.
3¡BThe teachers in the field of humanities and art generally use internet resources to teach, but many of them can not directly teach on the internet owing to the insufficiency of wireless environment.
4¡BThe information literacy of the teachers has a notably positive effect on the usefulness, the ease of use and the will to use of teaching with the wireless network.
5¡BThe effectiveness of how WIMAX influence the completion of building wireless teaching environment in junior high schools is not so obvious.

AUGMENTED REALITY FOR LOCATION-BASED ADAPTIVE MOBILE LEARNINGChang, William 21 January 2013 (has links)
Augmented Reality (AR) has become a popular interactive technique in the last few years. One of the critical challenges is to identify the real-life objects. Further, how to fully exert the advantages of the AR technique under the limited resources available on the mobile devices is another critical challenge. To resolve the above issue, firstly this thesis reviewed the real-life object tagging and identification techniques. Secondly this thesis studied the Human Computer Interaction (HCI) Interface and the environmental sensors on the mobile phones. Lastly this thesis implemented a Multiple Real-life Object Identification Algorithm along with the development of the Multi Object Identification Augmented Reality (MOIAR) application. Subsequently, the MOIAR application has been implemented in the location-based mobile learning environment, where the Legislative Assembly of Alberta is included as an example real-life learning object. This MOIAR implementation has applied the tagging and identification technique review as well as the HCI and sensors study, to prove the usability and practicability of the MOIAR application. / 2012-01

greater number of citizens anytime and anywhere. The potential increase of the
supply for mobile devices integrated to mobile learning environments allows that the
information comes out of the physical environment, creating opportunities for
students and teachers to create geographically distributed learning scenarios.
However, many applications developed for these environments remain isolated from
each other and do not become integrated sufficiently into the virtual learning
environments (AVA). This dissertation presents an interoperability model between
mobile devices and distinct AVA based on webservices. For the conception of this
model, requirements engineering and software architecture techniques were used.
With the goal of showing the model viability, a mobile application focused on

Manipulação de objetos 3D em ambientes colaborativos com o uso do dispositivo KinectSilveira Junior, Wedson Gomes da 22 February 2013 (has links)
The research on natural interaction has been growing significantly since, with the
spread of personal computers, there is an increasing demand for interfaces that
maximize productivity. Among these we can highlight the interfaces Virtual Reality
and Augmented Reality (KIRNER, TORI e SISCOUTO, 2006), where users can
perform simple tasks such as choosing a 3D object translation, rotation and scaling in
3D object.
These tasks are usually performed through devices such as the keyboard and
mouse, and can, thus, a loss of immersion happen by the user in the virtual
environment. Thus, investigating methodologies for natural interaction in these
environments, can help increase user immersion in the virtual environment.
Another issue that have been the focus of many researches are Collaborative Virtual
Environments (KIRNER e TORI, 2004), where it is possible for users to communicate
and share information. These users can be physically close or not. The main focus of
this work is precisely the communication among remotely dispersed users.
Thus, it is intended with this work, proposing a system where it is possible to
manipulate 3D objects using natural gestures and share data remotely dispersed
users. / As pesquisas na área de interação natural vêm crescendo significativamente, pois,
com a disseminação de computadores pessoais, existe uma demanda crescente por
interfaces que maximizem a produtividade. Dentre essas interfaces podemos
destacar a Realidade Virtual e a Realidade Aumentada (KIRNER, TORI e
SISCOUTO, 2006), de forma que os usuários possam realizar tarefas simples como:
escolha de um objeto 3D, translação, rotação e mudança de escala neste objeto 3D.
Essas tarefas normalmente são realizadas através de dispositivos como o teclado e
o mouse, podendo, dessa maneira, acontecer uma perda de imersão por parte do
usuário no ambiente virtual. Sendo assim, investigar metodologias para interação
natural nesses ambientes, pode ajudar a aumentar a imersão do usuário, no
ambiente virtual.
Outra questão que vem sendo o foco de muitas pesquisas são os Ambientes Virtuais
Colaborativos (KIRNER e TORI, 2004), que permitem aos usuários se comunicarem
e compartilhar informações. Esses usuários podem estar próximos fisicamente ou
não. O foco principal desse trabalho é justamente a comunicação entre usuários
dispersos remotamente.
Dessa maneira, pretende-se, com esse trabalho, propor um sistema que possibilite a
manipulação objetos 3D através de gestos naturais e compartilhar dados com
usuários dispersos remotamente. / Mestre em Ciências

A relaÃÃo de jovens com o saber: o uso de dispositivos mÃveis para aprender em uma escola profissionalizante do interior do CearÃEryck Dieb Souza 00 October 2018 (has links)
nÃo hà / O objetivo deste trabalho foi compreender a relaÃÃo de jovens, de uma escola profissionalizante do
interior do CearÃ, com o saber, por meio dos usos de dispositivos mÃveis para aprender na escola
e fora dela. Dessa forma, analisamos os mÃbeis e o(s) sentido(s) ligados Ãs aÃÃes comunicativas
desses jovens. O arcabouÃo teÃrico desta pesquisa abarcou os conceitos da relaÃÃo com o saber,
mobilizaÃÃo, atividade e sentidos de Charlot (2000; 2001; 2013) para se compreender quais
motivaÃÃes, sentidos e relaÃÃes os jovens construÃram com o saber por meio dos dispositivos
mÃveis, alÃm do conceito de aprendizagem mÃvel (M-learning) a partir das formulaÃÃes de
Sharples et al. (2005; 2009), Traxler (2009) e Saccol, Schlemmer e Barbosa (2011). A pesquisa,
de natureza qualitativa, abrangeu aÃÃes de 35 jovens, que participaram da coleta de dados, realizada
atravÃs da aplicaÃÃo do protocolo do balanÃo de saberes (CHARLOT, 2000; 2001; 2013) e
entrevistas semiestruturadas. O trabalho de coleta incluiu, ainda, um perÃodo de observaÃÃo
participante, durante seis meses, de um grupo no aplicativo WhatsApp intitulado âEnfermagem â
3Â anoâ, com procedimentos de coleta de telas, textos e imagens compartilhadas no meio digital. A
anÃlise dos dados foi direcionada pelos tipos ideais de Weber (1979), em que buscamos mapear a
relaÃÃo dos jovens com o saber por meio do uso dos dispositivos mÃveis. Os resultados da anÃlise
revelaram trÃs tipos ideais da relaÃÃo dos jovens com o saber por meio dos dispositivos mÃveis: 1)
apropriaÃÃo de conteÃdos curriculares ou das aprendizagens essenciais que permitem o
desenvolvimento de competÃncias e habilidades ao longo do processo formal de EducaÃÃo,
colaborando diretamente com a aprendizagem curricular e, tambÃm, com o fortalecimento
tÃcnico/profissional; 2) comunicaÃÃo livre com troca de informaÃÃes, por meio de conversas com
os colegas, nÃo necessariamente sobre os conteÃdos da escola, mas de vÃrias naturezas e 3) zapping
profÃcuo, relacionado ao aprender transitando na Internet, acessando sites com informaÃÃes mais
amplas e diversas, mas que chamam a atenÃÃo e para as quais conferem alguma importÃncia ou
valor. Esses resultados indicaram que por mais que tenhamos apresentado separadamente os tipos
ideais encontrados nesta pesquisa, no contexto dos participantes, ocorreram de forma
complementar, pois à medida em que zapeiam na Web, eles vÃo se apropriando de conteÃdos
essenciais para o currÃculo escolar e tÃcnico, com compartilhamentos e trocas, como tambÃm
construindo uma relaÃÃo com o aprender por meio do uso dos dispositivos mÃveis. O estudo
concluiu que os jovens, por meio dos dispositivos mÃveis e suas alternativas de espaÃo/tempo,
portabilidade, mobilidade e agilidade das informaÃÃes, conseguem atingir mais rÃpido e de forma
eficiente os saberes necessÃrios. AlÃm disso, acreditam que constroem seus saberes crÃticos quando
se apropriam dos dispositivos mÃveis para fins pedagÃgicos, concluindo que deixam de ser meras
tecnologias para se tornarem um elemento essencial da cultura juvenil e para a aprendizagem.

CAMLearn* : une architecture de système de recommandation sémantique sensible au contexte : application au domaine du m-learning / CAMLearn : a semantic context-aware recommender system architecture : application on m-learning domainSoualah Alila, Fayrouz 18 March 2015 (has links)
Au vu de l'émergence rapide des nouvelles technologies mobiles et la croissance des offres et besoins d'une société en mouvement en formation, les travaux se multiplient pour identifier de nouvelles plateformes d'apprentissage pertinentes afin d'améliorer et faciliter le processus d'apprentissage à distance. La prochaine étape de l'apprentissage à distance est naturellement le port de l'apprentissage électronique vers les nouveaux systèmes mobiles. On parle alors de m-learning (apprentissage mobile). Jusqu'à présent l'environnement d'apprentissage était soit défini par un cadre pédagogique soit imposé par le contenu d'apprentissage. Maintenant, nous cherchons, à l'inverse, à adapter le cadre pédagogique et le contenu d'apprentissage au contexte de l'apprenant.Nos travaux de recherche portent sur le développement d'une nouvelle architecture pour le m-learning. Nous proposons une approche pour un système m-learning contextuel et adaptatif intégrant des stratégies de recommandation de scénarios de formations sans risque de rupture. / Given the rapid emergence of new mobile technologies and the growth of needs of a moving society in training, works are increasing to identify new relevant educational platforms to improve distant learning. The next step in distance learning is porting e-learning to mobile systems. This is called m-learning. So far, learning environment was either defined by an educational setting, or imposed by the educational content. In our approach, in m-learning, we change the paradigm where the system recommends content and adapts learning follow to learner's context.

The Use of Mobile Assisted Language Learning for Vocabulary Acquisition in the English Classroom / Användningen av MALL för att utvidga ordförrådet i det Engelska KlassrummenHolmberg Svensson, Line, Sinclaire, Emma January 2022 (has links)
The increased need for digital education in upper secondary schools of Sweden during the COVID-19 outbreak showcased that there is a lack of professional knowledge in regards to what tools to use in order to vary the experience for the students in a virtual teaching environment. In this paper, we investigate whether Mobile-Assisted Language Learning (MALL) could assist English vocabulary acquisition of Swedish upper secondary students and what their attitudes are towards it. By finding and synthesizing studies that have been published on MALL in regards to vocabulary acquisition, we hoped to gauge the possible outcomes of applying it in Swedish classrooms as well. The majority of the analyzed studies showed positive results on both vocabulary acquisition and the students' attitudes. However, the methods of the experiments and the attitude questionnaires, along with the innate cultural differences, made us question whether we would see the same results in Swedish schools, but when considering the curriculum, the empirical evidence and learning theories, we still found enough relevancy and validity in the method to claim that MALL could work to assist vocabulary acquisition in the English classroom of Swedish upper secondary school.
