Σκοπός της παρούσας εργασίας είναι να μελετηθεί η αποδοτικότητα δύο οργανωμένων μαθησιακών δραστηριοτήτων με τη χρήση τεχνολογίας wiki. Προκειμένου να μελετηθεί η επίδραση των δραστηριοτήτων υιοθετήθηκε σχεδιασμός pretest-posttest. Τα αποτελέσματα υποδεικνύουν σημαντική βελτίωση στα μαθησιακά αποτελέσματα, ειδικά για τους φοιτητές με χαμηλή αρχική επίδοση. Επιπρόσθετα, οι φοιτητές εκφράζουν θετικές απόψεις από τη χρήση wiki στις δραστηριότητες. / The aim of this study is to investigated the effectiveness of two framed wiki-based learning activities. A one-group pretest–posttest design was adopted to examine the impact of the activity. The results showed significant improvement in learning outcomes, in particular for students with low initial performance. In addition, a positive attitude towards using wikis in their project was expressed by the students.

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.

Les travaux présentés dans cette thèse proposent différentes méthodes, réflexions et réalisations associant Web 2.0 et Web Sémantique. Après avoir introduit ces deux notions, nous présentons les limites actuelles de certains outils, comme les blogs ou les wikis, et des pratiques de tagging dans un contexte d’Entreprise 2.0. Nous proposons ensuite la méthode SemSLATES et la vision globale d’une architecture de médiation reposant sur les standards du Web Sémantique (langages, modèles, outils et protocoles) pour pallier à ces limites. Nous détaillons par la suite différentes ontologies (au sens informatique) développées pour mener à bien cette vision : d’une part, en contribuant activement au projet SIOC - Semantically-Interlinked Online Communities -, des modèles destinés aux méta-données socio-structurelles, d’autre part des modèles, étendant des ontologies publiques, destinés aux données métier. De plus, la définition de l’ontologie MOAT - Meaning Of A Tag - nous permet de coupler la souplesse du tagging et la puissance de l'indexation à base d’ontologies. Nous revenons ensuite sur différentes implémentations logicielles que nous avons mises en place à EDF R&D pour permettre de manière intuitive la production et l'utilisation d'annotations sémantiques afin d’enrichir les outils initiaux : wikis sémantiques, interfaces avancées de visualisation (navigation à facettes, mash-up sémantique, etc.) et moteur de recherche sémantique. Plusieurs contributions ont été publiées sous forme d'ontologies publiques ou de logiciels libres, contribuant de manière plus large à cette convergence entre Web 2.0 et Web Sémantique non seulement en entreprise mais sur le Web dans son ensemble. / The work described in this thesis provides different methods, thoughts and implementations combining Web 2.0 and the Semantic Web. After introducing those terms, we present the current shortcomings of tools such as blogs and wikis as well as tagging practices in an Enterprise 2.0 context. We define the SemSLATES methodology and the global vision of a middleware architecture based on Semantic Web technologies (languages, models, tools and protocols) to solve these issues. Then, we detail the various ontologies (as in computer science) that we build to achieve this goal: on the one hand models dedicated to socio-structural meta-data, by actively contributing to SIOC - Semantically-Interlinked Online Communities -, and on the other hands models extending public ontologies for domain data. Moreover, the MOAT ontology - Meaning Of A Tag – allows us to combine the flexibility of tagging and the power of ontology-based indexing. We then describe several software implementations, at EDF R&D, dedicated to easily produce and use semantic annotations to enrich original tools: semantic wikis, advanced visualization interfaces (faceted browsing, semantic mash-ups, etc.) and a semantic search engine. Several contributions have been published as public ontologies or open-source software, contributing more generally to this convergence between Web 2.0 and the Semantic Web, not only in enterprise but on the Web as a whole.

This thesis examines organizational use of social media. It focuses on developing an understanding of the ways by which social media are used within formal organizational settings. From the vantage point of this thesis such an understanding can be achieved by looking at tensions and incompatibilities that might potentially exist between social media and organization because of their distinct characteristics. It is argued that the distinct characteristics of social media (e.g. openness, transparency, flexibility, etc.) and organization (e.g., hierarchy, formal relationships, standard procedures, etc.) may engender tensions and incompatibilities that affect the ways of using social media and their potential in organizations. The main premise here is that the possibilities, behaviors and practices afforded by social media are recognizably different in nature from common and established organizational practices, behaviors, norms and routines. Through a structurational understanding of organizational use of social media, influenced by Giddens’ theory of structuration and Orlikowski’s practice lens for studying technology use, this thesis offers the perspective of immiscibility to capture tensions and incompatibilities driven by the distinctive characteristics of social media and organization. It basically offers a way of seeing social media use in organizations as a dynamic, in-practice interplay between social media and organization characteristics. One key argument in this thesis is that the immiscible interplay of social media and organization, produces, at least in transition, ‘a bureaucracy of social media’. Social media, it is argued, are used in ways that are essentially bureaucratic, reflecting and also reinforcing established characteristics of formal organizations through the production and reproduction of structures which are driven by the immiscible interplay. The development of such an understanding was achieved through multiple research studies focusing on the use of the wiki technology for knowledge collaboration and sharing practices in two large multinational organizations: CCC and IBM. A number of qualitative methods were used in these studies to collect empirical evidence from the two organizations including interviews, field visits, observations and document analysis. The overarching contribution of this thesis centers on offering a unique way of understanding organizational use of social media by putting forward tensions and incompatibilities between social media and organization and also by providing an understanding of how such tensions and incompatibilities affect the potential for change by social media.

Wikis sind dabei, sich als ein Werkzeug im unternehmensinternen Wissensmanagement zu etablieren. Ein Grund hierfür ist vor allem die Hoffnung, die Externalisierung von Wissen schnell, direkt und informell unterstützen zu können. Die einfache Handhabung eines Wikis und die vergleichsweise geringen Lizenzierungs-, Installations- und Betriebskosten eines Wiki-Systems bestärken diese Hoffnung noch. Doch bevor Wiki-Kollaboration in einem Unternehmen gelebt wird, müssen Barrieren auf unterschiedlichen Ebenen erkannt, analysiert und beseitigt werden. Ziel des vorliegenden Beitrages ist es, die Auswahl aus einer Vielfalt von Medien als Barriere für den erfolgreichen Einsatz von Wikis im Unternehmen zu erläutern. Diese hat sich - neben anderen Barrieren, die während der Wiki-Einführung bei der Robert Bosch GmbH in den vergangenen 18 Monaten identifiziert wurden - als erfolgskritisch herausgestellt.

No. of bitstreams: 1 Maurício Tessi de Souza.pdf: 1434399 bytes, checksum: 33e4b3f5814a662b1128ffd020800265 (MD5) Previous issue date: 2016-04-27 / Social software, eg Wikis, Blogs and Microblogs, have gained attention in recent years in the daily life of organizations, these can be incorporated into the project management and collaborative tools. Regarding organizations, these tools can facilitate the sharing of lessons learned and knowledge among employees of an organization and the external public. These facilities can be seen through the real-time communication, access to information by multiple people at the same time and control of information exercised by management or organization. Moreover, the lessons learned are one of the central points of this research, which contributed directly to the organization, management and the security project teams. This study aims to evaluate to what extent the use of an artifact produced by a lessons learned management model can contribute to the management of security projects. As research question of this study narrowed to the following, "To what extent the lessons learned Target 2.0 management model can contribute to the management of security projects?" To this end, this study uses the Design Science Research as a research paradigm and the Technical Action Research as a method, which will reduce the gap between research and practice. This work is characterized as qualitative, using interviews and direct observations techniques. We used a Wiki as a central tool of this artifact, noting the facilities of inputs, consultations and control of the lessons learned from the management and design teams. The device was applied to the organization through a Web 2.0 tool, ie a Wiki, which served as support and support to project teams in the collection of lessons learned. The study found that even the use of the artifact has contributed significantly to the practice of security projects, as there was an improvement in communication between staff and management. Another point seen in the study was the ease of use of the tool users in the process. One of the limitations is the availability of Internet, which is still a problem, because without Internet, the virtual tools or social media are compromised, being a hindrance to the team's work in the field. As a contribution to the theory the artifact created can improve Lessons Learned storage and communication between property security project teams and their managers in the researched organization. / Os softwares sociais, e.g. Wikis, Blogues e Microblogues, têm ganho atenção nos últimos anos no cotidiano das organizações, podendo estes serem incorporados à gestão de projetos como ferramentas colaborativas. No que tange às organizações, essas ferramentas podem facilitar o compartilhamento das lições aprendidas e o conhecimento entre colaboradores de uma organização e o público externo. Estas facilidades podem ser vistas através da comunicação em tempo real, do acesso às informações por várias pessoas ao mesmo tempo e do controle das informações exercido pela gestão ou pela organização. Além disso, as lições aprendidas são um dos pontos centrais desta pesquisa, a qual contribuiu diretamente na organização, na gestão e nas equipes de projetos de segurança. Este estudo tem como objetivo avaliar em que medida o uso de um artefato produzido por meio de um modelo de gestão de lições aprendidas pode contribuir para o gerenciamento de projetos de segurança. Como questão de pesquisa deste estudo delimitou-se a seguinte, "Em que medida o modelo de gestão de lições aprendidas Target 2.0 pode contribuir com a gestão de projetos de segurança?" Para tal, este estudo utiliza o Design Science Research como paradigma de pesquisa e o Technical Action Research como método, que permitem reduzir a lacuna existente entre a pesquisa e a prática. Este trabalho se caracteriza como qualitativo, utilizando as técnicas de entrevista e observação direta. Utilizou-se uma Wiki como ferramenta central deste artefato, observando as facilidades dos inputs, as consultas e controle das lições aprendidas entre a gestão e as equipes de projeto. O artefato foi aplicado na organização por meio de uma ferramenta da Web 2.0, ou seja, uma Wiki, a qual serviu como suporte e apoio às equipes de projeto na coleta das lições aprendidas. O estudo apontou ainda que o uso do artefato contribuiu significativamente para a prática de projetos de segurança, pois houve uma melhora na comunicação entre a equipe e com a gestão. Outro ponto percebido no estudo foi à facilidade de uso da ferramenta pelos usuários nos processos apresentados pelo modelo Target 2.0. Como limitações percebeu-se que a Internet ainda é um problema, pois sem ela as ferramentas virtuais ou as mídias sociais são comprometidas, sendo um empecilho para o trabalho da equipe em campo. Como contribuição para a teoria o artefato criado pode melhorar o armazenamento de Lições Aprendidas e a comunicação entre as equipes de projeto de segurança patrimonial e seus gestores na organização pesquisada.

Wiki Message Linking (WML) is a group communication tool that will be used between group members and the group leader. By using WML, group web pages are created and modified easily. From the WML, new pages are created and owned by their creators. The group leader and the page owner can modify the page, and the owner may give permission for other people to modify the web page; member can edit their works online and the leader can review the works and correct the works directly from the WML.
