摘要
Working memory capacity (WMC) plays an important role in the learning process, because learners need to hold and process some information in the short-term memory while they are engaged in learning activities. Measuring learners' WMC can be helpful to support and enhance their learning. For example, teachers can use this information to adapt their teaching strategies according to learners' level of WMC. In addition, information about learner's WMC can be exploited by adaptive e-learning systems for providing recommendations to support learners with low and high WMC. Furthermore, early detection of the level of individual learner's WMC is a very important step to be able to provide appropriate intervention for the learners. In this context, a number of tools are available in the literature to explicitly measure learner's WMC. However, most of them require considerable experience in the administration and interpretation of results. This study proposes an approach based on fuzzy logic for measuring learner's WMC in an unobtrusive manner, from learner's interactions with an educational game. Results of experiments proved the effectiveness of this method in measuring WMC. The educational game, used in this work, could help parents and teachers to know the WMC of their kids and learners. In addition, the proposed approach could be adapted by researchers working in this field to measure learners' WMC using other educational games.
