An evaluation framework based on timed automata for Malleable Learning Scenario

Abstract

The evaluation of educational scenario is important to educators. It is one of the more challenging tasks that the pedagogical designer is faced with. In fact, the higher cost of the implementation of learning scenarios in distance learning and the complexity of their context and their functionalities emphasize the need to evaluate and to simulate them in order to detect potential inconsistencies and then to provide valuable feedback and recommendations to designers. For these reasons, we propose, in this paper, a framework based on Timed Automata Theory for Malleable Learning Scenarios. The evaluation framework is based on four elements: time, space, role and activity. These elements can be used in order to evaluate if or not our educational scenario reveals inconsistencies. The result of this formal evaluation could be greatly useful to designers in order to increase their understanding of the learner's behavior with the existing scenario by revealing ambiguities and incompleteness that might otherwise go undetected before starting the implementation. Thus, designers could return on the phase of design to add missing elements.
