[en] FRAMEWORK FOR COORDINATION AND MEDIATION OF WEB SERVICES MODELED AS LEARNING OBJECTS FOR WEB-BASED LEARNING ENVIRONMENTS / [pt] FRAMEWORK PARA COORDENAÇÃO E MEDIAÇÃO DE WEB SERVICES MODELADOS COMO LEARNING OBJECTS PARA AMBIENTES DE APRENDIZADO NA WEB

REUBEM ALEXANDRE DALMEIDA GIRARDI 18 March 2005 (has links)
[pt] O crescente interesse em ambientes de aprendizado na Web incentiva pesquisas e torna evidente a importância do desenvolvimento de tecnologias e padrões que permitam ambientes, instrutores e participantes a criar, encontrar, consumir, reusar e compartilhar conteúdos instrucionais, conhecidos como objetos de aprendizagem ou learning objects. Padrões para metadados, objetos de aprendizagem e arquiteturas para prover suporte a estas tecnologias em sistema de ensino na web (learning management systems - LMS) são a chave para o sucesso do e-Learning. Neste sentido, o conceito de objetos de aprendizagem possui fundamental importância e concentra grande parte das pesquisas realizadas nesta área. Em paralelo, a observação de que o aprendizado na web ocorre através do auxílio de ferramentas e serviços que fazem parte dos LMS gera a reflexão sobre a atual modelagem e entendimento destes serviços. Com isso, este trabalho defende a modificação do conceito de learning objects, estendendo o atual, incorporando serviços à sua abrangência, sendo estes modelados com base na tecnologia de serviços web (web services). No final, é apresentado um framework para facilitar a adaptação de Learning Management Systems a este novo conceito de learning objects e o estudo de caso no Ambiente AulaNet. / [en] The increasing interest in web-based learning environments stimulates researches and evidences the importance of developing technologies and standards that allow environments, instructors and participants to create, find, consume, reuse, and to share instructional contents, known as learning objects. Metadata standards, learning objects and architectures to support these technologies in Learning Management Systems (LMS) are the key for the success of e-learning. In this context, the learning object concept has essential importance and concentrates the majority of the researches accomplished in this field. At the same time, observing that the learning in the web happens through the aid of tools and learning services which are part of LMS, leads to the reflection about the current modeling and understanding of these services. This work defends the modification of the learning objects concept, extending the current one by incorporating services to its extent, being these modeled as Web Services. Finally, a framework is presented in order to facilitate the adapting of the Learning Management Systems to the new concept of learning objects, as well as a case study in the AulaNet Environment.
