| Abstract [eng] |
Qualitative learning material (or Learning Objects – LOs) is one of the main factors of learning quality. Therefore, evaluation of LOs quality is one of the most relevant education problems. The problem is relevant for all participants of the educational sector – for educational institutions (e.g. schools) that have to select qualitative learning material for their needs, for education policy makers who need clear quality criteria while implementing LOs tenders, for authors of learning material (e.g. publishers) who need to know quality requirements to create LOs etc. The research work is aimed to propose and pilot LOs reusability and quality evaluation methodology, i.e., quality model, and simple and effective expert evaluation methods, thus improving solution of educational tasks using informatics engineering methods. To reach this aim, we have to analyse the notions of LOs reusability and expert evaluation of quality, principles of creating LOs reusability and quality model, and possible simple and effective methods for the expert evaluation of LOs quality and reusability. Both LO quality and reusability model and evaluation method are presented in the work. LO quality model created consists of 9 quality criteria divided into 3 groups i.e. technological, pedagogical, and IPR criteria. This model is comprehensive and matches scientific principles of creating a model. The following methods are selected and consecutively applied in the research while evaluating LOs quality and reusability level: scalarisation, fuzzy numbers theory principles, the experts’ evaluation compatibility and the experts’ utility function. In the work, experimental application of the model and method is performed (i.e., different examples of evaluating LOs alternatives are provided), and internet tool for evaluating LOs reusability and quality evaluation is created. LOs expert evaluation method created based on fuzzy numbers and scalarisation method is simply and effective while evaluating LOs alternatives in the market or creating qualitative LOs. The method created is suitable and practically applicable in education institutions for evaluating LOs quality and reusability. |
