Identification of the design variables of eLearning tools

The widespread availability of digital learning resources in a variety of media formats has promoted the proliferation of eLearning systems as an integral part of teaching across all sectors of education. However, these systems are rarely planned in advance taking into account its final usefulness. At most, they are validated through learner experience using the final implemented system. In this paper, a scientific technique called concept mapping is proposed to identify the external variables that should be kept in mind while designing an eLearning tool. As a result, improvements can be programmed to increase its utility in the teaching activities prior to its use. The method has been tested in the development of a eLearning system used for advanced microprocessor teaching. Results are shown through two-dimensional maps, in which variables can be seen as clusters or groups of ideas. These variables can be used as a guide for developing an eLearning tool. The reliability of the results is also analyzed to check the correct application of the proposed technique.
