Abstract

LODE is a logic-based web tool for Italian deaf children. It aims at stimulating global reasoning on e-stories written in a verbal language. Presently, we are focusing on temporal reasoning, that is, LODE stimulates children to reason with global temporal relations between events possibly distant in a story. This is done through apt exercises and with the support of a constraint programming system. Children can also reinvent the e-story by rearranging its events along a new temporal order; it is the task of the constraint system to determine the consistency of the temporally reorganised story and provide children with feedback. To the best of our knowledge, LODE is the first e-learning tool for Italian deaf children that aims at stimulating global reasoning on whole e-stories.
