RESUMO

The development of instructional content using new Information Technologies is an expensive, time-consuming and complex process that leads to the development of new methodologies. It was in this context that the concept of Learning Objects (LOs) was proposed as an approach that promotes content reuse. However, if content is expressed as small LOs, it is also necessary to sequence them in order to build more elaborated and complex content. In this thesis we adopt a strategy to represent smaller LOs, modeling not only content but also practice, called Component Objects (COs) herein. In order to structure content we adapted an existing proposal and defined a conceptual schema to structure learning practices (or activities). We also defined a conceptual schema for composing these COs. Then, based on these conceptual schemas it was possible to propose an algorithm for sequencing COs, which supports a teacher/professor to better control the implementation of a complex content such as a class or a course, thus reducing errors and eventual omissions in its implementation. The sequencing process must follow a methodology and must be specified in a nonambiguous way. It is in this context that we also present a specification language for sequences of LOs, with a syntax that is adequate to the description of the possible ways of sequencing LOs. Finally, we describe a case study that shows the conceptual schemas that were proposed and the use of the sequencing algorithm and the specification language.
