METHODOLOGY TO BUILD LEARNING OBJECTS USING SEMANTIC SIMILARITY MEASURES
Last years, teaching is in a process of transformation after the capture of new technologies. With the immersion of ICT in the teaching-learning process facilitates the use of information sources increasingly updated to provide both the student and teacher a better professional performance. Usually the contents of a textbook to work in the classroom are not enough for a student who needs to get to content with depth; therefore he/she requires additional teaching materials that can be consulted. In the majors at the Agronomy and Veterinary Medicine at the Agrarian University of Havana (UNAH) include subjects with high needs of laboratory practice and visual aids which not always can be carried out effectively or do not have the ideal samples to work with.
Due to the great use of images it was necessary an application to store and manage them efficiently with necessary descriptions to facilitate learning. That is why this paper proposes a methodology for creating learning objects in UNAH using domain ontologies and semantic similarity measures in the management of resources. A case study in which the proposal is validated and the relevance of this methodology is presented is determined. This methodology is part of the interests of the UNAH to support the computerization program of the university. The images are stored are learning objects that are described as the standard IMS-CP.
To validate the proposal two groups of students were selected. A sample of 15 students was selected to build their own knowledge, individually, with learning objects at their disposal. The other students do not have these objects were called control. To perform the study each of the periodic evaluations were performed by the students were analyzed. Both the quality and quantity of approved on assessments were taken into account In this sense the academic performance of each student is analyzed, and the group as a whole, these assessments included the final exam. The results of the study conducted were positive in the case of the sample, in which students developed new learning strategies, thus there was an increase in the quality of assessments and the academic score for each student, for the group and not for the control.
