Teacher-Centered Production of Hypervideo for Distance Learning

摘要

This paper introduces the main features of LEZI, a software tool oriented to the production of indexed videos (hypervideos), enriched with hypertextual and multimedia elements. In certain types of educational applications, the quality of educational content may compensate easily for a user interface limited to the essentials or a reduced set of multimedia features. Production of this kind of multimedia application can be high quality, even with short production cycles, at a very low cost. This work concentrates on this particular field with LEZI, a conventional conference/lesson that can be transformed effectively into a powerful multimedia product based on a very simple and regular structure. The authors hope that the LEZI environment, which does not require specific expertise in information technology, will allow the author of an educational multimedia product to work at a higher level than conventional authoring tools in a short time and at a low cost.
