Concept maps and learning objects

Concept maps constitute one of the tools frequently used in learning management as they offer the possibility to personalize learning, share knowledge and reinforce learning to learn skills. At the same time, many initiatives or standards are being developed rapidly to make the contents in different learning management systems and learning environments compatible. This paper states the need to combine the technique of Concept Maps with initiatives that package contents developed by IMS to produce more portable and powerful content. A model to create tools for learning management is proposed.

A Proposal for Disassembling Learning Objects with High Level of Aggregation. An Implementation for OpenCourseWare Educational Resources

Learning objects with high level of aggregation are very useful as a showcase of the possibilities of the different elements that composes them. The reusability of the whole high level learning object lays on the standard packaging technology is being used. But frequently, the teacher is only interested in a selection of the components or wishes to replace some elements by other ones.In this article, we present a proposal to deconstruct learning objects with high level of aggregation precedent from OpenCourseWare web sites and reuse selected components in different ways. Also, we present an implementation of this proposal as an example for the case of the OpenCourseWare educational resources.

CREATION OF A LIBRARY OF LEARNING OBJECTS (LO) FROM PRE EXISTING CONTENTS

Interoperability is essential in elearning systems. Many XML based standards have appeared which make easier the methods for describing, identifying and searching the LO created in different formats and Learning Management Systems (LMS), thus guaranteeing its reusability. In this context, SCORM standard, developed by Advanced Distributed Learning (ADL) is dominating. It is based on proposals of different organizations like IEEE Learning Technology Standards Committee (LTSC), Learning Object Metadata Working Group and IMS Global Learning Consortium. The most modern elearning LMS use the standards mentioned above to achieve interoperability among the different systems; nevertheless, there is much useful content which is available in different environments that is not structured according to the standards and provokes difficulties for its reusability. That is why it is necessary to look for alternatives to pack such contents to be imported and used in the existing LMS. An automated procedure to create Digital Libraries composed of Learning Objects from content structures previously created is proposed. Tools to make this process easier have been developed. It has been applied to contents created in a LMS for teaching Spanish and it has resulted in a Multimedia Digital Library of Learning Objects. Generacion de una biblioteca de Objetos de aprendizaje (LO) a partir de contenidos preexistentes Leonel Iriarte Navarro , Manuel Marco Such , Daniel Moron Martin, Carlos Perez-Sancho, Pedro Pernias Peco Departmento de Informatica, Universidad Agraria de la Habana, Cuba lin@infomed.sld.cu 2 Departmento de Lenguajes y Sistemas Informaticos, Universidad de Alicante, Espana mmarco@renr.es, Dani.Moron@ua.es, cperez@dlsi.ua.es, p.pernias@universia.net Resumen. La interoperabilidad se considera fundamental en los sistemas eLearning. Han surgido estandares basados en XML que facilitan metodos comunes de descripcion, identificacion y busqueda de objetos de aprendizaje (LO) desarrollados bajo diversos formatos y plataformas , que garantizan su reusabilidad. En este ambito se esta imponiendo el Estandar SCORM desarrollado por Advanced Distributed Learning (ADL) basado en propuestas de organizaciones como IEEE Learning Technology Standards Committee (LTSC), Learning Object Metadata Working Group y IMS Global Learning Consortium. Las plataformas eLearning mas modernas utilizan los estandares antes mencionados para lograr la interoperabilidad entre los distintos sistemas, sin embargo existe mucho contenido util, disponible bajo diversos entornos, que no esta estructurado segun los estandares, lo cual provoca serias dificultades para que puedan ser reutilizados. Por tal motivo se hace imprescindible la busqueda de alternativas que permitan empaquetar dichos contenidos de modo que puedan ser importados y utilizados en las diversas plataformas existentes. Se propone un procedimiento automatizado que permite construir Bibliotecas Digitales compuestas por Objetos de aprendizaje a partir de estructuras de contenidos desarrolladas previamente. Se han desarrollado herramientas que facilitan este proceso. Se ha aplicado a contenidos desarrollados sobre una plataforma para la ensenanza del espanol, obteniendose como resultado una Biblioteca Digital Multimedia de LO.
