[en] In today s world, knowledge management is a one of the key issues in searching, processing, and retrieving information according to users needs. It is especially important in on line educational systems, such as e-learning, where it is possible to access large quantity of information that is not always very relevant for users. As a consequence of semantic web, information management for e-learning systems is changing. No doubt, an important contribution from computer science to knowledge management and e-learning systems is the learning object (LO) concept. This element is characterized by an independent unit, which is able to be reused for other educational situations and platforms.In order to manage LOs without interoperability problems, specifications and standards are in development. However, the ability to interchange learning objects is not synonymous with high quality results. Research about quality LOs is a topic that has hadlimited focus and there are only a few published works dealing with their quality design. On this basis, our proposal is comprised of a system to manage quality LOs for e-learning systems in order to obtain educational and technical LOs that can receive continuous feedback to ensure their quality. Within knowledge management systems it is important to define what and how to manage. Therefore, we define the type of LOs we are managing and the evaluation processconsidering different kind of LO evaluation during the process (context, input, process and product). To achieve this we suggest different kinds of quality criteria, instruments and evaluation strategies, as well as the participants, in order to evaluate LOs. Our proposal is directed to educational and technical issues as well as LOs metadata. On this basis, we suggest how to add suitable information into some metadata categories. Inorder to promote consistent quality LOs, we take into account experts participationaccording to the OA subject, interface design and metadata. Finally, we suggest users participation for LO evaluation. As a result, the user will have the opportunity to evaluate the LO during and after the interaction process. To achieve this, students have to answer questions about their content quality and their satisfaction levels. This way it is possible to make adjustments in order to improve the LO quality. All information obtained from theevaluation may be given to experts and teachers to advance content design and to guarantee a continuous quality content re-feed.

[es] La gesti?n del conocimiento es hoy en d?a un aspecto clave para buscar, procesar y recuperar informaci?n adecuada seg?n las necesidades de los usuarios. Esto resulta especialmente importante en sistemas de formaci?n no presencial como e-learning donde es posibleacceder a una gran cantidad de informaci?n que no siempre resulta relevante. A consecuencia del desarrollo de la web sem?ntica, la informaci?n a gestionar en sistemas elearningest? cambiando. Sin duda, una importante contribuci?n desde las ciencias de la computaci?n es el concepto de objetos de aprendizaje (OAs), se caracteriza por ser unaunidad independiente, capaz de ser reutilizada en diversas plataformas y situaciones educativas.Para gestionar OAs sin problemas de compatibilidad entre las plataformas, diversas organizaciones se encuentran desarrollando est?ndares y especificaciones e-learning. Sin embargo, la posibilidad de que los OAs puedan ser intercambiados no significa que el contenido de ?stos sea de calidad. El objetivo de esta propuesta es promover una gesti?n de calidad t?cnica y pedag?gica de OAs para un entorno e-learning, en donde los OAs representen unidades educativas eficientes que puedan ser constantemente realimentadas para garantizar su calidad.En un sistema de gesti?n es importante definir el qu? gestionar, c?mo y qui?nesintervienen en la gesti?n. Sobre esta base, en esta propuesta se define el tipo de OAs a gestionar y un proceso para evaluar los OAs en diversos momentos del proceso de gesti?n (contexto, entrada, proceso y producto) a trav?s de diferentes criterios, instrumentos y estrategias de evaluaci?n, indicando adem?s qui?nes deben participar en esta tarea.La evaluaci?n propuesta de los OAs est? dirigida a valorar aspectos pedag?gicos yt?cnicos del recurso, como tambi?n sus metadatos. Sobre esta base, se sugieren indicaciones que ayuden a introducir informaci?n adecuada en ellos. Para promover de forma continua OAs de calidad, se propone inicialmente una valoraci?n por parte de expertos que tenga conocimiento en el tema que trata el OA, dise?o de interfaz y metadatos. Finalmente, se sugiere la valoraci?n de los estudiantes durante el proceso de interacci?n con el OA y al t?rmino de cada lecci?n, para lo cual deben responder preguntas sobre la valoraci?n del OAy su propia satisfacci?n. De esta manera, se pretende realizar los ajustes necesarios para mejorar a?n m?s su calidad.
