A Model for Semi-Automatic Composition of Educational Content from Open Repositories of Learning Objects

Learning objects (LOs) repositories are important in building educational content and should allow search, retrieval and composition processes to be successfully developed to reach educational goals. However, such processes require so much time-consuming and not always provide the desired results. T...

Repositorios de objetos de aprendizaje Recursos educativos abiertos Tecnología educativa Material educativo Teoría educativa. Learning objects (LOs) repositories are important in building educational content and should allow search, retrieval and composition processes to be successfully developed to reach educational goals. However, such processes require so much time-consuming and not always provide the desired results. Thus, the aim of this paper is to propose a model for the semiautomatic composition of LOs, which are automatically recovered from open repositories. For the development of model, various text similarity measures are discussed, while for calibration and validation some comparison experiments were performed using the results obtained by teachers. Experimental results show that when using a value of k (number of LOs selected) of at least 3, the percentage of similarities between the model and such made by experts exceeds 75%. To conclude, it can be established that the model proposed allows teachers to save time and effort for LOs selection by performing a pre-filter process. Los repositorios de Objetos de Aprendizaje (OA) son importantes para la construcción de contenidos educativos y deben facilitar los procesos de búsqueda, recuperación y organización de OA con el fin de atender objetivos educativos. Sin embargo, estos procesos demandan tiempo y no proveen los resultados esperados; por ello, el objetivo de este artículo es proponer un modelo para la organización semiautomática de contenidos recuperados automáticamente de repositorios abiertos. Para el desarrollo del modelo se analizaron medidas de similitud, mientras que para su calibración y validación se realizaron experimentos de comparación con los resultados obtenidos por docentes. Los resultados experimentales demuestran que al usar un valor de k (selección de OA) de 3, el porcentaje de coincidencias entre el modelo y los expertos supera el 75%. Se concluye entonces que el modelo propuesto permite ahorrar tiempo y esfuerzo al docente para seleccionar OA al realizar un proceso de prefiltrado.
