Evaluación de un modelo de calidad para objetos de aprendizaje basado en un modelo

Abstract

This work describes the process to create a quality model that allows the evaluation of Learning Objects (LO), considering technological and didactic aspects. To achieve this goal, existing quality models considering both aspects were identified and reviewed together with the concepts of LO and software quality. The i* notation was used to build a strategic dependence diagram (SD) describing the typical context of a Learning Object (context actors and their intentionality in relation to the LO) and the IQMC method to build the final quality model. Trazability among the strategic dependencies identified in relation to the external actors present in the context model and the characteristics and subcharascteristics included in the quality model described in the ISO/IEC 25010, is established. The objective is to make evident the relation existing among them and to identify in a systematic way, the quality properties that structure the first decomposition levels of the quality model under construction. These first levels are decomposed into more basic quality properties, using attributes included in the models identified in the literature review in addition to other models that have emerged in this study. Required measures have been associated to each quality property included in the quality model, in order to evaluate LO in an objective manner. To validate this work, the resulting quality model has been used to evaluate an existing LO.
