This diploma thesis deals with the topic of multimedia learning objects and authoring systems for its design. In the form of a qualitative survey the paper discovers the most frequent practice teachers' requirements for these objects and systems. Subsequently, the paper carries out theoretical analysis of commonly available authoring systems for multimedia learning object creation and performs their evaluation from the point of view of the identified requirements. After that, the thesis notes that there is no authoring system available on the market that would adequately meet the requirements identified. Therefore, the paper works on the design and realization of such a system. Finally, the designed and implemented system is deployed in a real educational environment and its contribution to the teacher's work is validated by accomplished action research.

O Governo Brasileiro, juntamente com outros órgãos públicos e representantes do terceiro setor, criou um grande número de projetos que tentam disseminar o uso das tecnologias e promover a inclusão digital. Esses projetos são consequência da importância dada à inclusão digital e à capacitação do cidadão como ser autônomo e crítico no uso das tecnologias e na construção do seu conhecimento. Entretanto, a escola, que deveria ser considerada a principal responsável pelo futuro cidadão, ainda não consegue acompanhar o avanço das tecnologias e da sociedade fora dos seus muros, vivendo um momento de grandes questionamentos. As tecnologias já fazem parte do cotidiano da escola, mas não provocaram mudanças significativas nos processos de ensino e aprendizado como as que se observam fora dos muros da escola. Nossos alunos vivem hoje uma realidade fora da escola muito diferente da que a escola lhes oferece, o que prejudica a relação da escola com o aluno e com a sociedade. As mídias, poderosos recursos para a produção de conteúdos educacionais, estão presentes no cotidiano desses usuários, ávidos em consumirem desenhos animados, filmes e jogos eletrônicos. Entretanto, os usuários ainda são tratados como meros espectadores, que não passam de passivos consumidores que recebem todas as informações prontas, continuando reféns de uma parcela da sociedade que possui o poder de produzir e manipular estas informações. Este trabalho apresenta um estudo sobre interfaces naturais em sistemas de autoria para filmes de animação, bem como a concepção, desenvolvimento e resultados de testes de dois protótipos de sistemas. Apresenta também considerações e subsídios para o desenvolvimento de sistemas de autoria que estimulem a produção de filmes de animação de maneira fácil e intuitiva a partir de interfaces naturais com foco no processo de produção do usuário. Em vivência, os protótipos desenvolvidos se mostraram de fácil e rápida apropriação por crianças de diferentes faixas etárias, que se mostraram interessadas em explorar e construir suas animações. Os resultados obtidos mostram a viabilidade da proposta do trabalho e fornecem subsídios para o desenvolvimento de novos sistemas. / The Brazilian Government, along with other public agencies and representatives of the third sector, has created a large number of projects that try to spread the use of technologies and promote digital inclusion. These projects are the result of the importance given to digital inclusion and empowerment of the citizen as an autonomous being and critical user of technology as well as autonomous in his knowledge construction. However, the school, which should be considered the main responsible for the citizens\' future, still can not keep pace with advancing technology and society outside its walls, living a moment of great questions, since the technologies are already part of its daily but caused no significant changes in the teaching and learning as occurring outside the school walls. Today, student\'s reality outside school is very different from what school offers them, which undermines the school\'s relationship with the student and society. The digital media, with powerful resources for content production, are present in daily lives of the users, eager to consume cartoons, movies and computer games. However, users are still treated as simple spectators who are merely passive consumers and receive all the information ready, still hostage to a portion of the society that has the power to manipulate and produce this information. This work presents a study on natural interfaces to authoring systems for animation films, as well as presents the design, development and results of tests of two prototypes. It also presents considerations and subsidies for the development of authoring systems that encourage production of animated films in an easy and intuitive way, using natural interfaces and focusing on the production process and user evolution. In preliminary experiments, the prototypes proved to be easy and quickly learned, which matches the goals of this project to attract users in different age groups who had shown interest in exploring and building their own animations. The results and contributions obtained show the feasibility of the proposed work and can also provide subsidies for the development of new systems.

No. of bitstreams: 1 Agnaldo Martins Rodrigues.pdf: 3935190 bytes, checksum: 46b1f019444554c37a2d064289176869 (MD5) Previous issue date: 2014-01-31 / Nenhuma / Com o uso crescentedas tecnologias de informação e comunicação na área educacional, torna-se cada vez mais necessária a criação de ferramentas de apoio ao professor, capazes de auxiliá-lo no planejamento e execução das aulas, bem como no acompanhamento do processo de ensino-aprendizagem. Em alguns casos, o acesso a essas tecnologias, aliado ao conhecimento técnico limitado por parte dos docentes, pode comprometera maneira com que os conteúdos são desenvolvidos e utilizados pelos alunos. Essa é a principal área de pesquisa da presente dissertação, que se propõe a ajudar a tornar mais proficiente esse processo, pelo menos no contexto do ensino de dedução natural na disciplina de Lógica, através da criação de uma ferramenta inteligente de autoria e acompanhamento de uso de materiais educacionais, na forma de objetos de aprendizagem. A ferramenta, denominada SAAPIEnS,torna possível que o professor elabore objetos de aprendizagem customizáveis no domínio específico de dedução natural na lógica proposicional. Com base em um conjunto de ações, regradas por estratégias de ensino, almeja-se também instrumentalizar o docente no acompanhamento das atividades realizadas pelos alunos no ambiente computacional, apoiando o processo de avaliação do nível dedesempenho alcançado pelos alunos. Isso é feito por meio de um subsistema que oferece serviços de visualização e análise de dos conjuntos de interações dos alunos com os objetos de aprendizagem. A ferramenta é disponibilizada tanto via Web quanto via local (desktop), visando a uma maior flexibilidade para professor e alunos. Os possíveis impactos dessa ferramenta foram avaliados através de cenários hipotéticos de uso, que ilustram as principais contribuições possíveis para esse tipo de ferramenta. / With the increasing use of information and communication technologies in education, it becomes necessary to create supporting tools which can assist teachers in planning and implementing lessons as well as monitoring the process of teaching and learning. In some cases, access to these technologies, coupled with limited technical knowledge on the part of teachers, can compromise the way the contents are developed and used by students. This is the main research area of this dissertation, which aims to make this process more proficient, at least in the context of teaching natural deduction in the discipline of logic, through the creation of an intelligent authoring tool of learning objects, which also allows the teacher to follows the use of these educational materials by students. The tool, called SAAPIEnS, makes it possible for the teacher to prepare customizable learning objects in the specific domain of natural deduction in propositional logic. Based on a set of actions, regulated by a set of teaching strategies, the goal is to help teachers to monitor the activities performed by students in the computing environment, supporting the process of assessing the level of performance achieved by the students. This is done by means of a subsystem, which offers visualization and analysis service of the sets of interactions of students with learning objects. The tool supports Web and local (desktop) interfaces, giving greater flexibility for teachers and students. The possible impacts of this tool were evaluated through hypothetical usage scenarios that illustrate the main possible contributions to this type of tool.

L’objectif de cette thèse est de fournir un modèle, une méthode et un outil d’aide à la réalisation de scénarios interactifs. Cette solution répond au problème de l’opposition entre la maîtrise du déroulement d’un jeu vidéo et son niveau d’interactivité. En d’autres termes, notre but est d’aider à réaliser des jeux vidéo dont l’évolution satisfait les intentions des auteurs tout en autorisant un déroulement influencé par les choix du joueur (exprimés aux travers de ses actions). Pour cela, notre proposition permet à l’utilisateur de produire un modèle de scénario de jeu de bonne qualité qui est : (a) riche – le scénario fournit suffisamment d’options pertinentes aux personnages joueur/non-joueur de sorte que le joueur puisse déterminer le déroulement du jeu et sente toujours que le discours créé est intéressant, (b) valide – tous les discours possibles dans le scénario sont cohérents et répondent aux effets désirés par les auteurs, (c) opérationnel – la représentation du scénario est exécutable. Ce scénario est ensuite employé comme l’entrée d’un système de pilotage de narration interactive assurant le contrôle de la gestion du déroulement du jeu. Par conséquent, l’évolution des jeux, qui sont dirigés par un tel système de pilotage, garantit que l’exécution du jeu respecte les souhaits des auteurs, et en même temps, autorise la liberté des actions du joueur. Pour répondre au problème exposé ci-dessus, nous appuyons notre solution sur un modèle mathématique calculable (la logique linéaire) qui offre des mécanismes de déductions rigoureux et automatiques.Nous avons fait un tour d'horizon des approches existantes concernant le pilotage de narration interactive et la validation de scénario. Ceci nous permet d'identifier les principes nécessaires à notre solution, tels que les éléments d'architecture d'un système de pilotage ; la construction,la représentation, l'exécution de scénarios narratifs ; les propriétés de narration importantes ; l'évolution de référence des paramètres dramatiques ; la structuration de discours ; la stratégie pour la validation d'un scénario ; les informations qualitatives et statistiques nécessaires… Nos contributions portent (1) sur la définition d'un ensemble de propriétés de narration spécifiant la qualité des scénarios de jeu ; (2) sur la proposition de modèles, algorithmes et outils pour écrire des modèles de scénario respectant ces propriétés. Nous validons nos résultats par la réalisation de deux exemples. Le premier est un extrait d'un jeu éducatif expliquant comment appliquer notre outil en vue de produire un modèle de scénario de jeu valide, qui est exprimé par un séquent de logique linéaire dont la représentation est conforme à un métamodèle du calcul des séquents. Pour le second exemple, nous décrivons le processus de production complet d'un jeu vidéo réel basé sur l'histoire « Le Petit Chaperon rouge », mettant en oeuvre un prototype de système de pilotage que nous avons proposé, ce qui permet de dérouler le jeu selon le scénario valide produit, donc son évolution satisfait les intentions des auteurs, et en même temps, dépend des actions du joueur. / The objective of this PhD thesis is to provide a model, a method and a tool for producing interactive scenarios. Our solution solves the opposition between the controlle devolution of a video game and its interactivity level. In other words, our goal is to assist (authors) in producing video games whose unfolding satisfies authors’ intentions while it is simultaneously influenced by player’s choices (expressed via her/his actions).To this purpose, our proposal is to allow users to produce a good quality game scenario model, which is: (a) rich – the scenario provides enough pertinent options for player/non-player characters so that the player can determine the evolution of the game and always feels that the created discourse is interesting, (b) valid – all the possible discourses in the scenario are consistent and meet authors required effects, (c) operational – the representation of the scenario is executable. This scenario is then used as the input of an interactive storytelling control system to assist it in managing the unfolding of the game. As a consequence, the evolution of the video games, which are directed by such a control system, guarantees authors requirements, while at the same time, it depends on player’s actions. In order to execute the foregoing proposal, we base our solution on a calculable mathematical model (linear logic) which provides rigorous and automatic deduction mechanisms. We have made an overview of existing approaches concerning interactive storytelling controland scenario validation problems. This allows us to identify necessary principles for our solution, such as: architecture elements of a control system; construction, representation, implementation of narrative scenarios; important narrative properties; reference evolution of the drama parameters; discourse structuralization; scenario validation strategy; necessary statistical and qualitative information; etc. Our contributions consist (1) in the definition of a set of narrative properties specifying the quality of game scenarios; (2) in the proposal of models, algorithms and tools in order to produce scenario models respecting these properties. We validate our results by realizing two examples. The first is an extract of an education algame explaining how to apply our tools to produce a valid game scenario model, which is expressed by a linear logic sequent whose representation conforms to a metamodel of the sequent calculus. For the second example, we describe the complete production process of areal video game based on the story "Little Red Cap", implementing a prototype of control system we have proposed, which allows unfolding the game according to the produced valid scenario, so its evolution satisfies authors intentions and simultaneously depends on player's actions.
