DIGITAL LIBRARIES AND LEARNING OBJECTS REPOSITORIES

Discusses the technological changes that affects learning organizations as well as the human, technical, legal and sustainable aspects regarding learning objects repositories creation, maintenance and use. It presents concepts of information objects and learning objects, the functional requirements needed to their storage at Learning Management Systems. The role of Metadata is reviewed concerning learning objects creation and retrieval, followed by considerations about learning object repositories models, community participation/collaborative strategies and potential derived metrics/indicators. As a result of this desktop research, it can be said that not only technical competencies are critical to any learning objects repository implementation, but it urges that an engaged community of interest be establish as a key to support a learning object repository project. On that matter, researchers are applying Activity Theory (Vygostky, Luria y Leontiev) in order to seek joint perceptions and actions involving learning objects repository users, curators and managers, perceived as critical assets to a successful proposal.

Dos diagramas aos parâmetros: transformações no design digital

The article is part of an ongoing theoretical research about the emergence of parametric architecture. It discusses some of the last developments in digital design from the transition of the discourse and operativity by “diagrams” to the theories and processes derived from “parameters”. Centered in Peter Eisenman’s and Patrik Schumacher’s propositions, it is in its horizon to comprehend what relations are established between “diagram” and “parameter” -­‐ similarities, complementarities and differences -­‐, contributing for the critical contextualization of theoretical movements and design processes in contemporary architecture.
