I-Questions of the lesson indexed in a WIS oriented to the e-learning

In the present work, a tool called Indexed Questions (IQ), integrated in the system of the “indexed lesson” object of a previous work is described, and allows the learner to ask queries on-line with the possibility to attach them to an index that directly goes to the interested video-lesson part. These queries once stored in the database, appropriately organised from the teaching team , will enrich the system knowledge base, guaranteeing at the same time high levels of interactivity, all following a didactic paradigm of the WIS-learning object of our research group . The tool object of the present work, wants to underline the development of a system that overcomes the “classical” tools today present in the e-learning environment, that is able to enrich the information share between the learners and able to increase the interactions with the teacher, favouring the reaching of the main aims at the basis of the constructivist model.According to the IQ system, the learner has moreover at his/her disposal various access modalities to the IQ catalog, according to the following dimensions: time dimension, semantics dimension, IQ pushing dimension. flat-access dimension. Finally, in the application, the teacher’s possibility of communication in direct chat from the video-lesson web page has been anticipated, that happens automaticaly following the activation from the part of the teacher.
