An obstacle in this direction is the difficulty of\r\nvalidating any automatic tool created to help on the evaluation of adaptive\r\nsystems. In this work a simulation-based technique is proposed as an\r\neconomic way for testing evaluation tools based on log analysis. Simulog,\r\na tool that implements this simulation technique, is also presented.","note":"","tags":"simulation, e-Learning, adaptive environments"}

En este sentido, la utilizacion de herramientas\r\nautomaticas de evaluacion puede ser de gran ayuda. Por este motivo, en\r\neste art\u0131culo se propone una arquitectura para incorporar herramientas\r\nde evaluacion automatica en el contexto de un Sistema Hipermedia Adaptativo\r\norientado a la Educacion.

Such material can be accessed at any\r\ntime from anywhere using different devices, and can be personalized according\r\nto the individual student\u2019s needs, goals and knowledge. However, authoring and\r\nevaluation of this material remains a complex a task. While many researchers\r\nfocus on the authoring support, not much has been done to facilitate the\r\nevaluation of e-Learning applications, which requires processing of the vast\r\nquantity of data generated by students. We address this problem by proposing an\r\napproach for detecting potential symptoms of low performance in e-Learning\r\ncourses. It supports two main steps: generating the production rules of C4.5\r\nalgorithm and filtering the most representative rules, which could indicate low\r\nperformance of students. In addition, the approach has been evaluated on the log\r\nfiles of student activity with two versions of a Web-based quiz system.","note":"","tags":""}

One of the main concerns with AEHS is to test and decide whether adaptation strategies are beneficial for all the students or, on the contrary, some of them would benefit from different decisions of the adaptation engine. Data mining (DM) techniques can provide support to deal with this issue; specifically this chapter proposes the use of DM techniques for detecting potential problems of adaptation in AEHS.","note":"","tags":"data mining, education, adaptive","weight":"13"}
