In this context it is acknowledged that universities have an important role innovating in the educational use of digital media to promote an inclusive digital literacy. The educational potential of digital technologies and resources has been recognized by both researchers and practitioners. Multiple pedagogical models and research approaches have already contributed to put in evidence the importance of adapting instructional and learning practices and processes to concrete contexts and educational goals. Still, academic and scientific communities believe further investments in ICT research is needed in higher education. This study focuses on educational models that may contribute to support digital technology uses, where these can have cognitive and educational relevance when compared to analogical technologies. A teaching and learning model, centered in the active role of the students in the exploration, production, presentation and discussion of interactive multimedia materials, was developed and applied using the internet and exploring emergent semantic hypermedia formats. The research approach focused on the definition of design principles for developing class activities that were applied in three different iterations in undergraduate courses from two institutions, namely the University of Texas at Austin, USA and the University of Lisbon, Portugal. The analysis of this study made possible to evaluate the potential and efficacy of the model proposed and the authoring tool chosen in the support of metacognitive skills and attitudes related to information structuring and management, storytelling and communication, using computers and the internet. Keywords: semantic hypermedia, higher education, design-based research, digital storytelling, internet Resumo A crescente utilização das tecnologias da informação e comunicação (TIC) nos mais diversos contextos profissionais e pessoais requer um conjunto de novos conhecimentos, capacidades, competências e atitudes para uma cidadania ativa e participativa. Neste enquadramento defende-se que as instituições do ensino superior têm um papel importante no sentido de promover uma literacia digital inclusiva, inovando na utilização educativa dos media digitais. O potencial educativo das tecnologias e conteúdos digitais tem sido reconhecido por muitos investigadores e professores, havendo no entanto a consciência junto da comunidade académica e científica, da necessidade de mais investimentos no estudo da utilização de TIC no ensino superior. A multiplicidade de modelos pedagógicos e de abordagens de investigação têm contribuído para evidenciar a importância de adaptar as práticas e processos de ensino e aprendizagem aos contextos e objetivos educativos concretos. Este estudo centra-se em modelos educativos que permitam potenciar a utilização das tecnologias digitais em aspetos em que os contributos destas, do ponto de vista cognitivo ou educacional, se fazem diferenciar com mais evidência de outras tecnologias analógicas. Recorrendo à exploração de formatos de hipermédia semântico emergentes e ao uso da internet, desenvolveu-se e aplicou-se um modelo de ensino-aprendizagem centrado no papel ativo do aluno na exploração, produção, apresentação e discussão de conteúdos multimédia interativos. A abordagem de investigação focou a definição de princípios de design de atividades integradas na prática letiva tendo sido realizadas três implementações em disciplinas da oferta curricular de duas instituições do ensino superior, designadamente na Universidade do Texas em Austin, USA e na Universidade de Lisboa, Portugal. Foi possível verificar o potencial e a eficácia do modelo proposto e da aplicação autora escolhida para suporte e motivação dos alunos no desenvolvimento de competências e atitudes metacognitivas associadas à gestão e estruturação de informação, à narrativa e comunicação com recurso aos computadores e à internet.

    REFRAMING INTERACTIVE DIGITAL NARRATIVE: TOWARD AN INCLUSIVE OPEN-ENDED ITERATIVE PROCESS FOR RESEARCH AND PRACTICE A Dissertation Presented to The Academic Faculty By Hartmut Koenitz In Partial Fulfillment Of the Requirements for the Degree Doctor of Philosophy in Digital Media Georgia Institute of Technology August, 2010 Copyright © Hartmut Andreas Koenitz 2010 Reframing Interactive Digital Narrative: Toward An Inclusive Open-Ended Iterative Process For Research And Practice Approved by: Dr. Janet Murray, Advisor Dr. Kenneth Knoespel School of Literature, Communication Ivan Allen College and Culture Georgia Institute of Technology Georgia Institute of Technology Dr. Mads Haahr Dr. Jay Bolter Department of Computer Science School of Literature, Communication Trinity College Dublin and Culture Georgia Institute of Technology Date Approved: June 30, 2010 Dr. Celia Pearce School of Literature, Communication and Culture Georgia Institute of Technology It is a waste of energy and resources to make applications that merely imitate media that exist in other forms, such as print, television, and film. Pamela Jennings, 1996 To my Parents ACKNOWLEDGEMENTS First and foremost I want to acknowledge the help, dedication and commitment of my advisor Janet Murray. Her relentless criticism and simultaneous encouragement sharpened both my wit and the focus of my arguments. Jay Bolter gave me the courage to start this project and provided not only lucid intellectual advice, but also a shoulder to lean on and a voice of sanity in the darkest hours of this thesis. Celia Pearce gave me a new appreciation of games and encouraged me to include installation pieces I would have otherwise overlooked. Kenneth Knoespel always took my mind to exciting and unforeseen places and made me think outside the box.

  • The Living Documentary: from Representing Reality to Co-Creating
    The Living Documentary: from representing reality to co-creating reality in digital interactive documentary by Sandra Gaudenzi A thesis submitted for the degree of Doctor of Philosophy. Goldsmiths (Centre for Cultural Studies), University of London. London, January 2013. I hereby declare that this thesis is entirely my work Sandra Gaudenzi Date: 2 Abstract This thesis concentrates on the emerging field of interactive documentaries. Digital interactive and networked media offer so many new possibilities to document reality that it is necessary to define what an interactive documentary is and whether there is any continuity with the linear documentary form. This research therefore proposes a definition of interactive documentaries and a taxonomy of the genre based on the idea of modes of interaction – where types of interactions are seen as the fundamental differentiator between interactive documentaries. Interactivity gives an agency to the user – the power to physically “do something”, whether that be clicking on a link, sending a video or re-mixing content - and therefore creates a series of relations that form an ecosystem in which all parts are interdependent and dynamically linked. It is argued that this human-computer system has many of the characteristics associated with living entities. It is also argued that by looking at interactive documentaries as living entities (Living Documentaries) we can see the relations that they forge and better understand the transformations they afford – on themselves and on the reality they portray. How does an interactive documentary change while it is being explored/used/co-created? To what extent do such dynamic relationships also change the user, the author, the code and all the elements that are linked through the interactive documentary? Those questions are discussed through the use of case studies chosen to illustrate the main interactive modes currently used in interactive documentaries.
