This paper introduces a set of resources that provide web learning environments with student modeling services. SAMUEL is a user modeling server for registering, updating and maintaining student knowledge data from different sources that use their own ontologies.

Se han desarrollado muchas aplicaciones educativas para la web y su efectividad ha sido probada en situaciones reales. Sin embargo, el coste de desarrollo de estos sistemas es muy elevado por lo que numerosos investigadores est?n concentrando sus esfuerzos en la reutilizaci?n de software de calidad, construido sobre s?lidos fundamentos te?ricos y estrategias de ense?anza efectivas. En este resumen se presenta MEDEA: MEtodolog?as y herramientas para el Desarrollo de entornos inteligentes de Ense?anza y Aprendizaje, que comprende una metodolog?a de desarrollo para sistemas educativos inteligentes para la web basada en la reutilizaci?n de software existente como recursos de instrucci?n y un marco de trabajo, basado en la misma, que ha sido utilizado con ?xito para la construcci?n de sistemas para distintos dominios integrando herramientas desarrolladas independientemente.

This paper presents some experiences in training working memory and attentional control supported by an educational software system called APRENDO. The aims were to assess the suitability of the APRENDO system as a computer-based learning system in terms of improvements in these two executive functions, and to establish whether the tasks help children - especially children with the poorest performance - in a school task requiring the use of both processes. The participants were 52 four-year-old children, divided into a control group and an experimental group. The experimental group trained with two types of APRENDO visuospatial exercises: “Find the different objects” and “Find the intruder”. Before and after the training phase, all the children performed a school task with similar psychological demands selected from their ordinary school materials. The results of both APRENDO exercises showed positive correlations between the same variables over the training sessions, demonstrating the suitability of the exercises. On the other hand, in the experimental group, there were significant differences between some of the variables analyzed, e.g., the time needed to complete the exercises (“Answering time”) or the number of clicks on the correct images (“Answer accuracy”) in both exercises during the sessions. The results indicate that the children who obtained lower scores in the pre-test phase were those who benefitted the most from training. The analysis of the errors made by the children in both tasks suggests that these errors are due to the incorrect application of the same cognitive abilities. The implications for educational practice are discussed.

The research goals include the definition of new components for automatic assessment, open learner modelling, and adaptive recommendation of learning tasks. The development goals are substantiated in the construction of web based applications and services that can be integrated in a mush up architecture to build an intelligent and domain independent ...

In this paper we describe an on-going research work (MEDEA project) whose final goal is to develop a general framework to build open ITS. We understand “open system” as a set of autonomous educational modules that communicate between themselves following high-level pre-established protocols. Each of those modules can be an intelligent component with its own instruction strategies or a support tool that leaves all the adaptive capabilities to the ITS instructor core. The architecture opens up the possibility to include ...
