In the area of e-learning, there are new challenges to be overcome. One of them is to allow students self-regulation of their learning. Within this self-regulation process, students and teachers use technological tools to carry out their tasks. In general, these tools do not consider pedagogical aspects. Emerging approaches propose the use of electronic portfolios and semantic technologies to provide pedagogical characteristics that make tools more user-friendly for both teachers and students. This paper presents a conceptual model of an intelligent system to support self-regulated learning. This model is based on semantic technologies and uses the concepts of learning paths and student e-portfolios. For learning path generation, the system considers the different learning levels that a student should achieve and metrics that measure student progress. In this way, it proposes a learning path with the intention that the student achieves as highest learning level as possible.
In learning environment, portfolio is used as a tool to keep track of learner's progress. Particularly, when it comes to e-learning, continuous assessment allows greater customization and efficiency in learning process
Resumen -Los sistemas de administración de aprendizajes (LMS) han sido desarrollados usando diferentes plataformas y tecnologías. Consecuentemente uno de los principales desafíos es brindar la posibilidad de compartir recursos y componentes de estos sistemas. Con la posibilidad de usar tecnologías semánticas, más específicamente ontologías, se hace más fácil contar con LMS que permitan a los educadores compartir recursos.Principalmente este trabajo aborda el problema de compartir un recurso educativo especial que es la evaluación. En este sentido, se presenta el desarrollo y la implementación de una ontología que permite describir adecuadamente las evaluaciones en contextos de e-learning con el objetivo de facilitar y mejorar el reuso de tales recursos por parte de los profesores, dando soporte a la interoperabilidad de e-evaluaciones y al trabajo colaborativo. Esta ontología está basada en estándares de metadatos para describir objetos de aprendizajes ampliamente usados en la comunidad y en los sistemas de LMS.

Consequently, sharing learning resources and components has become a major challenge. E-assessment as a primary activity of any learning process is facing the same challenges and problems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
