Digital materials used in teaching and learning are called learning objects (LO). Traditionally, LOs were developed for use as support materials for teacher. However, they can be used by students or whoever is interested in learning something. LOs can be found in repositories and also on the Web, in teachers and institutions sites. In spite of that, they are not easily found. Repositories address few knowledge fields and few languages. Search engines return a large amount of information that makes it difficult for users to identify relevant LOs to meet their goals. In this context, this paper proposes a new mechanism for LOs retrieval, based on Web 2.0 principles. Among the options for Web 2.0 applications, the model of social bookmarking called our attention because it provides facilities to store links to LOs, and also to share and classify these links. Moreover, unlike what happens with the repositories, in these tools, any user can post new links, without restrictions. The prototype of this tool was called VITAE. VITAE provides links to LOs, in a way that people can store, organize and share them with others.... view less

Objetos de aprendizagem (OA) são materiais digitais utilizados para apoiar o ensino e a aprendizagem. Tradicionalmente, OAs são desenvolvidos como material de apoio a professores. Entretanto, eles podem ser utilizados por alunos ou qualquer pessoa interessada em aprender um determinado assunto. OAs podem ser encontrados em repositórios ou na Web, em sites de docentes e de instituições de ensino. Apesar disso, nem sempre os OAs são facilmente encontrados. Em geral, os repositórios abordam poucos campos do conhecimento e poucas opções de línguas. As máquinas de busca retornam um grande volume de informação, o que dificulta, para o usuário, identificar os OAs que são relevantes para as suas necessidades. Nesse contexto, este artigo propõe um mecanismo para recuperação de OAs, baseado nos princípios da Web 2.0. Dentre as opções de aplicações Web 2.0, o modelo de bookmarking social se destaca por facilitar o armazenamento de links a OAs e por permitir o compartilhamento e a classificação desses links. Além disso, ao contrário do que ocorre com os repositórios, essas ferramentas permitem que qualquer usuário possa postar novos links, sem restrições. O protótipo dessa ferramenta foi denominado VITAE. VITAE oferece o serviço de bookmarking social, de forma que usuários possam armazenar, organizar, avaliar e compartilhar links com outras pessoas.... view less
