Abstract. Reuse of computer based learning material is a key requirement for any practical approach to support adaptive and dynamic teaching/learning inside and outside the classroom. Unlike hardware technology innovations, the software support for reuse inside the classroom is still not satisfactory. We present an approach to reuse material based in the Computer-integrated Classroom (CiC) environment and a special type of active documents used for containing learning material defined by the user to fit the particular needs of a lecture. This approach allows collaboration at two levels. The first one involves learning unit authors, who can jointly develop a course and teach it independently. The second level of collaboration refers to teacher and students exchanging and sharing documents. This framework does not impose a certain teaching/learning style. It rather supports the seamless transition from one teaching/learning mode to another one, using the same material.

Abstract. Learning Object Metadata (LOM) is an interoperable standard focused on enabling the reuse of learning material for authoring lessons. Nevertheless, few work was done on taking advantage of LOMsemantics to facilitate retrieval of learning material. This article suggests an original approach which uses the structure of a lesson in order to automatically generate LOM-semantic-based queries whereas the user continues to formulate easy-to-write queries without semantic specifications. This proposal consists of a four-component framework attempting to consider the main issues of semantic-based retrieval of documents.
