RESUMO

The effort to maintain contents in ILE (Intelligent Learning Environments) was the inspiration behind the development of this work. It was observed that the contents to be taught are heavily reliant on these environments, which makes their sharing with other systems difficult. In addition, these materials are created with internal tools, which offer few resources for the instructional designer. In order to enable more content-rich resources to be exploited by this type of environment, this work presents the development of an infrastructure for managing, adapting and presenting content in the SCORM (Sharable Content Object Reference Model). This work presents an overview of standards and specifications in educational technologies, describes the SCORM model, comments on Component Based Software Engineering, and summarizes the JEE (Java Enterprise Edition) technology. The infrastructure is made available as a component, called CELINE, which can be coupled to the JEE web applications. It was divided into two sections: a framework for execution of SCORM packages, and another for generating these web environments. Customized tags are provided for the construction of JSP pages, enabling access to the resources of the component. In terms of management, it is possible to download and keep SCORM packages, register users, and view data on the content accessed by users. The component allows the execution of SCORM packages in 2004 3rd Edition, which was the latest version at the time this paper was written. In relation to adaptation, the environments can set up courses from parts of other courses, as well as change the structure of the course as the student interacts with it. Data persistence can be achieved through XML files, relational database or some other tool created by the developer. This work specifies the architecture and its implementation process. During the execution of this work, four learning environments were developed: BRUCE (Basic Reference for Use of the CELINE component) which serves as a reference and documentation for the use of the component; SAGAA, an ITS (Intelligent Tutor System) developed as CCW (Course Conclusion Work) in order to inspire and validate resources for adaptation of content; ALICE 2.0, a learning environment of UNIVALI used by students of Algorithms I, and ASTRO, a learning environment of FURB used by students in three classes of two disciplines in the Bachelor in Computing, Computer Science and Information Systems. The four environments are also described in this work. The component has also been submitted to compliance tests provided by ADL (Advanced Distributed Learning), which is responsible for maintaining SCORM. The test results are presented in this work, demonstrating that environments that use the component can receive the "LMS SCORM 2004 3rd Edition Conformant" seal. At the end of this work, the conclusions of the development and use of the environments tested by the students are described, and suggestions are given for future work
