Knowledge management for e-learning based on learning objects: a qualitative focus

In today´s world, WWW as a platform to deliver instruction enables e-learning systems to manage a large quantity of different digital content. Teachers contribute their expert knowledge and students contribute their investigation works, tasks, etc. As a consequence of this, the content repository grows with a lot of information. Then, an urgent need exists to retrieve the specific information they really need through e-learning systems. reusable learning object (LOs) concepts and standards for their application represent an advantage for knowledge management systems for e-learning systems. Users are able to manage and reuse content according to their needs without interoperability problems. However, the quality of the LOs content is not guaranteed. This paper attempts to analyze what must be considered to knowledge management for e-learning systems together with LOs and standars implication. A definition of LOs is proposed and quality criteria are suggested to evaluate LOs according to their characteristics and specific contexts.
