Todėl švietimo įstaigose skatinama išnaudoti visas IKT galimybes tobulinti mokymosi metodus ir mokymosi kokybę. Pirmajame skyriuje supažindinama, kas tai yra tradicinis mokymasis bei kaip keitėsi mokymosi metodika, kai buvo pradėtos naudoti informacinės komunikacinės technologijos. Antrasis skyrius skirtas projektinės dalies aprašymui. Sukurta lietuvių kalbos kurso dalis, skirta amerikiečių lietuvių kalbos žinioms tobulinti. Kurso kūrimui pasirinkta „Moodle“ virtuali mokymosi aplinka, nes ji yra paprasta, atviro kodo bei turi daug kitų privalumų. Trečioji dalis skirta kurso kokybės vertinimui. / This master thesis discusses the integration of the traditional and distance learning approaches into the virtual learning. The rapid development of information technologies made huge impact on the learning technologies, as well as changed the way of the students’ learning. Therefore, learning institutions are encouraged to employ all the possibilities provided by information and communication technologies in order to improve learning methods, as well as the quality of learning. The first chapter introduces traditional learning approach and presents how learning methods developed with the rise of information and communication technologies. The project part is described in the second chapter. The Lithuanian language course was designed to provide American students with the required material and improve their language skills. The course was created using “Moodle”, an Open Source Course Management System. The third chapter discusses the evaluation of the course quality.

Summary Distant Learning (DL) in Lithuania is rapidly developing, various Virtual Learning Environments (VLE) emerge. The most popular of them are WebCT, Moodle, Atutor. Therefore I have decided to analyse Moodle Virtual Learning Environment as it is widely used by many institutions of high and secondary education. Purpose of the paper To analyse the tools of virtual learning environments, in order to select those that could be added to Moodle environment and help achieve efficient usage of Moodle in creating and providing DL courses. Objectives: a) Analyse the concept and functions of VLE. b) Provide general analysis of VLE. c) Provide a comparative analysis of Moodle, File3, WebCT environments. d) Determine which functions should be added to VLE Moodle. e) Integrate the selected tools to Moodle environment. f) Prepare methodical material of Moodle environment for teachers and students. Methods of the study: a) Search and systemization of information. b) Analysis and generalization of scientific and informational material. c) Data processing. d) Comparative data analysis. In order to achieve the set objective I have compared Moodle and WebCT, which have proven to be the most popular VLE, as well as File3 – an average level VLE created in Finland. By comparing these VLE becomes apparent that Moodle VLE contains a number of various teaching and handling tools however the distributed versions of this program are short of some tools: they have no internal e-mail, which is...

The data mining is usable to easer analysis of these information. The object of work is to make a system for preprocessing and data mining of data, obtained from virtual learning environment Moodle. The historical learning data can be analysed after preprocessing to study learners learning intensity with data mining algorithms by StatSoft STATISTICA 7 software. k-means cluster analysis was applied as example of data mining of learning data. Recommendations to further application of data mining of learning activities are given, too.

Nowadays, in the new era of technology, everything needs to be updated, which represents a new challenge to education to adapt to the developments in technology. Moreover, due to the gap of theory separating practices in business schools, it is becoming obvious that the Universities can hardly help students to acquire experience. Due to this problem, business schools can limit the potential of students’ success. This study examines the efficiency of technology use in class as well as outside of the classroom. This was done by interviewing five teachers within different areas of teaching in Jönköping International Business School. The results show that there are many aspects that need to be considered such as policy, teacher development, the development of the virtual learning environment and other technological improvements, before applying technology in flipped classroom. / Den nya eran av teknik i dagens samhälle gör att allt måste uppdateras. Detta utgör en ny utmaning för utbildningen som bör anpassa sig till denna tekniska utveckling. Dessutom, som en följd av det teoretiska gapet som separeras från praxis i handelshögskolor är det tydligt att universiteten knappast kan hjälpa studenter att skaffa sig underförstådd kunskap. På grund av det här problemet kan handelshögskolor begränsa potentialen av studentens framgång. Däremot visar vår forskning att användningen av tekniken i det flippade klassrummet kan bidra till att förbättra situationen. Denna studie undersöker effektiviteten i teknikanvändning i klassrummet såväl som utanför klassrummet genom att intervjua fem lärare inom olika områden av undervisning på Jönköping Internationella Handels Högskola. Resultaten visar att det är många aspekter som bör beaktas, såsom policy, utvecklingsarbete av lärare, utveckling av VLE i tillägg till andra tekniska förbättringar, innan man applicerar tekniken i det flippade klassrummet.

The need for change within the Further Education sector in line with technological developments in our current society was apparent within my teaching practice. This led to a number of thoughts about virtual learning environments and its application within the teaching role. The role of the computer as a real socio-cultural learning environment was explored to examine if this environment could be nearer to the concrete experiential and situated learning environment that students came from at an early age. It was hoped that this would be a different learning environment that would start slowly and grow in an organic way. It involved the growth of a very different culture of learning, a learning environment that may include a different literature and with different ways of thinking about what is to be learned and how to learn it. It was also hoped that the virtual learning environment would provide a very powerful strategy to allow the operation of the principle of variation and selection which it needed within the college Learnwise Educational system. Education should shift from individual, technology-free cognition to a resourceful collaborative learning, and distributed intelligence. Learners should be empowered through thoughtful and innovative use of technologies, and benefit from social distributions of cognitions. Salomon et al.'s (1998) commented that education should pay more attention to the "effects of" technology rather than the "effects with" technology, so that autonomous performance may be achieved. The attempt of the first part of the research has been to investigate a student-centred strategy in a computer supported collaborative learning environment to see whether this kind of higher-order knowledge can be distributed among peers and environment. The starting point of the second part of my research focussed on the links between constructivist theory and knowledge management in relation to college teaching practice. Since this research formed part of a whole college restructuring of teaching and learning, a baseline for current practice was necessary. Literature concerning the use of technology was explored in order to benchmark where the college was at the start of the research. As a result of this initial investigation, a survey of current college practice resulted in a paper being accepted by the HE Academy at their 8th Annual Conference in 2007. Page 6 Results from this research indicated that, although the college displayed similar results to other FE establishments, it was imperative that a move to a new building with a digital environment philosophy required more than merely a physical move. As a result, research into emerging technologies was deemed to be important if the college was to take advantage of a new digital teaching concept. Investigation into collaborative tools and Web 2.0 techniques was seen as appropriate at this stage. The study of computer-supported collaboration included the study of this software and social phenomena associated with it. Through this element of research it was hoped to investigate these collaborative techniques in the light of constructivist theories in order to develop an appropriate and effective digital teaching model. Expanding the research to explore portal technologies, with a particular focus on the integration of teaching practice, would hopefully highlight a possible path connecting current practices to an educational portal and illuminate the benefits and challenges of such an endeavour. Acquiring and deploying Web-based collaborative functionality within an organisation has become a strategic move to improve relationships between employees, partners and customers. The ultimate aim of the research and hence the thesis being addressed, will be to show that it is possible to create a “Learning or College Gateway” as a solutions framework that helps improve education by integrating the tools staff and students already use and puts them to work connecting people with the information and processes they need to teach, learn and manage more effectively. This will create a powerful educational portal that enables the people throughout the college to share information and work together on activities from a single point of access. The gateway will therefore use innovative collaboration and communications technologies to help staff get more out of existing applications using familiar tools and extending the value of investment made in existing learning environment technologies. The aim of the research was partly answered by using project based scenarios which gave some staff a new insight into the use of ICT. However, those involved in projects were generally the more pro-active teachers. A slightly different approach is needed and College Management has been advised to explore the use of an interactive college intranet and a dedicated eLearning team as a possible way forward.

Esta inser??o deve ocorrer de forma que alunos e professores aproveitem ao m?ximo esses instrumentos, e passem a utiliz?-los com o intuito de agregar mais valor aos processos de ensino e aprendizagem. Para que isso ocorra, ? fundamental que os ambientes virtuais forne?am conte?do adequado, objetos de aprendizagem atraentes, al?m de serem din?micos e altamente adapt?veis ?s necessidades e interesses dos estudantes durante as sess?es de aprendizagem, visando a melhoria cont?nua do processo educacional para professores, tutores e estudantes. O presente trabalho tem como objetivo principal apresentar um modelo computacional probabil?stico, que pode ser incorporado ?s estruturas dos ambientes virtuais de aprendizagem, a fim de auxiliar no processo de detec??o autom?tica das tend?ncias e prefer?ncias dos estilos de aprendizagem do estudante, utilizando uma combina??o do modelo proposto por Felder e Silverman para estilos de aprendizagem, o FSLSM, com as t?cnicas de infer?ncia probabil?stica dos modelos ocultos de Markov (HMM). Para a valida??o do modelo, foram realizados experimentos em um simulador computacional capaz de reproduzir parcialmente o processo de intera??o do estudante com o ambiente virtual de aprendizagem, realizando um processo de infer?ncia com base no comportamento do estudante, ao qual foi utilizado o algoritmo de Viterbi para este prop?sito. Ao final, os resultados dos experimentos s?o apresentados e demonstraram um elevado grau de precis?o no processo de infer?ncia do estilo de aprendizagem probabil?stico. / Disserta??o (Mestrado Profissional) ? Programa de P?s-Gradua??o em Educa??o, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2016. / The great challenges of the present day in the development of computer technologies in educational process is to produce solutions that are able to respond properly to the teaching and learning methods, and define the most appropriate way to incorporate these mechanisms at school. This integration should take place so that students and teachers make the most of these instruments, and start to use them in order to add more value to teaching and learning processes. For this to happen, it is critical that virtual environments provide appropriate content, appealing learning objects, and are dynamic and highly adaptable to the needs and interests of students during the learning sessions, aimed at continuous improvement of the educational process for teachers, tutors and student. This study aims to present a probabilistic computational model, which can be incorporated into the structures of virtual learning environments, auxiliary order in the automatic detection process of the trends and preferences of student learning styles using a combination of the proposed model by Felder and Silverman to learning styles the FSLSM, with the probabilistic inference techniques of hidden Markov models (HMM). To validate the model, experiments were performed on a computer simulator able to partially reproduce the student interaction process with the virtual learning environment, making an inference process based on the student?s behavior, where we used the Viterbi algorithm to this purpose. At the end, the results of the experiments are presented and demonstrated a high degree precision in the process of inference of probabilistic learning style.

Esta pesquisa apresenta a especificação, desenvolvimento e aplicação de um sistema de mapeamento de indícios de mediação em ambientes virtuais de ensino-aprendizagem – AVEA. Este sistema visa o apoio ao processo de mediação pedagógica a professores que desenvolvem atividades vinculadas a Educação a Distância – EAD, objetivando reduzir a sobrecarga de trabalho desses na identificação e acompanhamento da evolução das mediações realizadas no ambiente. Para isso, utilizamos técnicas de mineração de textos com o emprego de mecanismos de inferência bayesiana para identificação de categorias de mediação a partir de interações realizadas entre os participantes de um curso na modalidade a distância. A validação do sistema e avaliação dos resultados foi realizada através de um estudo de caso, aplicado em uma disciplina de um curso de Pós-Graduação da UFRGS na área de Informática na Educação. Os dados utilizados nesta pesquisa foram obtidos a partir das interações armazenadas no ambiente virtual de ensino-aprendizagem Moodle do Centro Interdisciplinar de Novas Tecnologias na Educação. No decorrer da investigação foram selecionados estudantes da disciplina para mapeamento das interações realizadas. Com o mapeamento de tais interações e identificação das categorias de mediação para cada estudante, foram gerados gráficos e relatórios com informações sobre o processo de mediação. As categorias de mediação auxiliam na identificação dos níveis de mediação. Na análise dos resultados, as informações obtidas em tais gráficos e relatórios foram trianguladas com informações provenientes da entrevista com um dos tutores e a visão do pesquisador envolvido no estudo de caso. Os resultados apontam que a utilização de um sistema de mapeamento de indícios de mediação em ambientes virtuais de ensino-aprendizagem, com adoção da tecnologia de mineração de textos, torna possível a identificação de níveis de medição dos participantes de um curso na modalidade a distância. / This research presents the specification, development and employ of a system to mapping evidences of mediation on Virtual Learning Enviroments – VLE. This system aims to support the mediation process to teachers who develop educational activities related to distance education, aimed at reducing the workload of the teacher during the identification and attendance of the mediations evolution in the environment. For this, we use techniques of text mining with the employ of bayesian inference mechanisms to identify mediations categories from the users interactions in the online course. The system validation and evaluation of results were performed through a case study applied to a discipline of graduate course of the UFRGS about Computers in Education. The data used in this research were achieved from the interactions stored in the Moodle virtual learning environment of the Interdisciplinary Center of New Technologies in the Education. During the investigation were selected students from the discipline to interactions mapping. With the interactions mapping and identification of the mediations categories for each student were created graphics and reports with informations about mediation process. The mediation categories aid to identify levels of mediation. In analyzing the results, the information obtained from such graphs and reports were triangulated with information from an interview with the tutor and the vision of the researcher involved in the case study. The results shown that the use of a system to mapping evidences of mediation in virtual learning environments, with the choice of the text mining technology makes it possible to identify levels of mediation of the participants of a course in the distance modality.

Este trabalho de tese apresenta o Modelo Presença Plus (PPlus) para identificação de pistas textuais denotadoras de presença social em interações discursivas feitas por alunos em fóruns e chats educacionais. O grau de presença social (PS) é um indicativo de como os sujeitos interagem entre si e com o ambiente de aprendizagem; sendo considerado, na literatura, significativo para o desenvolvimento de relacionamentos e fortalecimento de sentimento de pertencimento no grupo. O trabalho se baseia na vertente Pragmática da Linguística, campo que enfatiza a importância de se considerar o contexto de produção dos eventos comunicativos e a dinâmica dialógica entre os interlocutores. Considerando que o mapeamento das interações dos discentes para detectar e avaliar seu grau de presença pode se constituir uma tarefa complexa e morosa para tutores de cursos a distância, desenvolveu-se um software para realizar o processamento automático das mensagens eletrônicas visando torná-lo uma funcionalidade a ser adicionada a ambientes virtuais de ensino e aprendizagem (AVEAs). Apesar de alguns impasses referentes, particularmente, aos aspectos sintáticos dos textos, os resultados obtidos no processamento, por lexicometria, das postagens foram satisfatoriamente semelhantes aos levantados na análise manual. O modelo PPlus e a escala de graus de PS foram também testados em um segundo ambiente disponibilizado na plataforma Moodle, tendo apresentado resultados equivalentes. A sondagem com professores e tutores de cursos a distância forneceu dados que corroboram a proposta de uma ferramenta a ser inserida em AVEAs de modo a facilitar o acompanhamento de estados afetivos, grau de envolvimento e interação entre os participantes no e com o ambiente. / This thesis presents Presence Plus (PPLus), a model for identifying indicators of social presence in text-based interactions made by students in educational forums and chats. The degree of social presence (SP) can be an indicator of how individuals interact among themselves and with the learning environment, and is considered by the literature to be relevant for the development of relationships and the strengthening of the sense of belonging in the group. This study is based on Pragmatics, an area of Linguistics that emphasizes the importance of the context in communicative events and the dialogic dynamics among speakers. Considering that mapping students’ interactions, as well as detecting and evaluating their degree of SP, may be a complex and time-consuming task in distance learning tutoring, a software was developed to do the automatic processing of posts, aiming at making it a possible functionality in virtual learning environments (VLEs). Despite the few conflicting results, mostly related to textual syntactic relations, data from processing tests using lexicometrics were satisfactorily similar to those obtained by manual analysis. The PPlus model and the SP scale were also tested in a different course in the Moodle platform. Results from this experiment presented equally positive data. Feedback from the questionnaire answered by teachers and tutors working in distance learning courses support the proposal of a tool that may facilitate their assessment of affective states, involvement and text-based interaction dents within the environment.

Essa tese busca compreender as maneiras pelas quais estudantes do PROEJA se utilizam das Tecnologias da Informação e Comunicação no seu saber-fazer subsequente, uma vez que os egressos dessa modalidade educacional devem tornar-se cidadãos e profissionais produtivos numa sociedade cada vez mais complexa e tecnológica. Por meio do acompanhamento de grupos virtuais de aprendizagem interturmas do Instituto Federal Fluminense de Educação, Ciência e Tecnologia, campus Macaé, procura-se determinar até que ponto os estudantes assim formados conseguem utilizar, no cotidiano/vida profissional, o que foi experenciado como metodologia do ensino formal de Biologia. Como referencial foram utilizadas a pedagogia dialógica de Paulo Freire aplicada ao conceito de letramento no contexto de uma cibercultura e a proposta de Edgar Morin sobre os saberes indispensáveis para a compreensão e inserção no mundo. A metodologia usada é a de estudo de caso, proporcionado um acompanhamento rigoroso e aprofundado dos grupos escolhidos. Ao longo da pesquisa, observou-se que os estudantes em pauta, embora sejam imigrantes digitais e apresentem resistências ao uso de computadores, desenvolvem estratégias de apreensão da ferramenta, indicando a possibilidade de sua posterior utilização competente. Como possibilidades futuras a serem desenvolvidas a partir do estudo realizado, e apontando na direção a novas pesquisas a serem implementadas, pode-se pensar na disciplina escolar Informática como base para realização da integração da matriz curricular, assegurando dessa forma maior contato estudante-ferramenta, no sentido de assegurar seu letramento digital e, dessa forma, traçar caminhos para sua efetiva inserção digital. / This thesis dissertations aims at understanding the ways by which students enrolled in the PROEJA program use Information and Communication Technologies in their posterior “knowing and doing”, since former students of this educational level should be productive professionals and citizens in an increasingly complex and technological society. By following virtual learning groups of learners at the Instituto Federal Fluminense de Educação, Ciência e Tecnologia, Macaé campus, this study tried to determine how much those learners can use, in their everyday/professional life, what was experienced in the methodological approach used in the formal teaching of Biology. As theoretical references, this thesis is supported by the dialogical pedagogy of Paulo Freire, applied to literacy within cyberculture, and Edgar Morin’s proposal on the essential set of knowledge for understanding and insertion in the world. The methodology used in the research consisted of a case study, which provided a rigorous and close tracking of the groups selected for the investigation. The research found out that the aforementioned students, though digital immigrants presenting resistance to computer use, developed strategies to incorporate the tool, a fact that indicates the possibility of its future competent use. Results of the study suggest likely future developments, including formal teaching of Computer Basics as an integrative subject in the curriculum. This may assure greater student-tool contact, thus guaranteeing his/her digital literacy, and determine ways for an effective digital inclusion.

The implementation of this proposal was based on reflections about the literacies submitted by Shetzer and Warschauer (2000), Soares (2002), Xavier (2005), Araújo (2007), Fischer (2007) and Ribeiro (2008). Located in the qualitative paradigm, with predominantly descriptive marks, our analysis suggested the categorization of online activities present in the courses Língua Inglesa II – A: Compreensão e Produção Oral e Leitura e Produção de Textos Acadêmicos updated at VLE Solar, from Universidade Federal do Ceará, and the description of literacy practices in virtual environments mediated, potentially, by the guidelines of the online activities proposed. The parameters considered for the analysis came from the summarization of Shetzer and Warschauer’s theoretical elaboration (2000), which lead us to the following dimensions of digital literacy: communication, construction and research. The data prompted the formation of an online activity typology, based on the literacy types demanded by them, namely: online activities strange to the potential of the web; online activities mediating the familiarization of the potential of the web; online activities mediating literacies for communication; and online activities mediating literacies for construction and research. The results of this analysis allowed the description of the literacy practices that are currently being privileged in this context, linking the type of online activity to the literacy practices that are potentially mediated by them and to the dimensions of digital literacy, according to Shetzer and Warschauer (2000). It follows that there is a need for technological formation for the language professional, because this way there will be the offering of online activities that addresses to the most diverse, or even countless, literacy practices in virtual environments. / Esta dissertação objetiva analisar as relações entre letramentos e atividades on-line presentes em Ambientes Virtuais de Aprendizagem (AVA). A execução desta proposta baseou-se nas reflexões acerca dos letramentos apresentadas por Shetzer e Warschauer (2000), Soares (2002), Xavier (2005), Araújo (2007), Fischer (2007) e Ribeiro (2008). Situada no paradigma das pesquisas qualitativas, de cunho predominantemente descritivo e exploratório, nossa análise propôs a categorização das atividades on-line presentes nas disciplinas Língua Inglesa II – A: Compreensão e Produção Oral e Leitura e Produção de Textos Acadêmicos, atualizadas no AVA Solar, da Universidade Federal do Ceará, e a descrição das práticas de letramentos em ambientes virtuais mediadas, em potencial, pelas orientações das atividades on-line propostas. Os parâmetros considerados para a análise foram oriundos da sumarização da elaboração teórica dos autores Shetzer e Warschauer (2000), o que nos levou às seguintes dimensões do letramento digital: comunicação, construção e pesquisa. O tratamento dos dados suscitou a formação de uma tipologia das atividades on-line, baseadas nos tipos de letramentos demandados por elas, a saber: atividades on-line alheias às potencialidades da web; atividades on-line mediadoras da familiarização com as potencialidades da web; atividades on-line mediadoras de letramentos para a comunicação; e atividades on-line mediadoras de letramentos para a construção e pesquisa. Os resultados dessa análise possibilitaram a descrição das práticas de letramentos que atualmente estão sendo privilegiadas neste contexto, vinculando o tipo de atividade on-line encontrada às práticas de letramentos que são potencialmente mediadas por essas e às dimensões do letramento digital, segundo Shetzer e Warschauer (2000). Como conclusão, verificou-se a necessidade de formação tecnológica para o profissional da linguagem, pois só assim poderá haver o oferecimento de atividades on-line que contemplem as mais diversas, senão inúmeras, práticas de letramentos em ambientes virtuais.
