Samcco : un Système d'Apprentissage Mobile Contextuel et Collaboratif dans des Situations Professionnelles

Abstract : With the rapid development of mobile computing technologies, mobile learning has become a new important learning style in our life. Situated, contextual, personal, collaborative, informal and lifelong are the main characteristics of mobile learning. We are interested in applying mobile learning in contextual professional situations, particularly in the learning of mastering domestic, public and professional appliances. In our work, a learning system named SAMCCO (French acronym of Collaborative Contextual Mobile Learning System) which concerned MOCOCO (Mobility, Contextualization, Collaboration) concepts was proposed for the above aimed situations. The research involved the domains of mobile technologies, mobile learning, learning context, contextualization, learning methods, CSCW (Computer Supported Cooperative Work), HCI (Human Computer Interaction) and AR (Augmented Reality). The problem of learning units was firstly studied. We considered learning units and their models as the learning resources for appliance mastering in our approach. We defined AMLOM (Appliance Mastering LOM) metadata to describe learning units. AMLOM metadata were extended from IEEE LOM (Learning Object Metadata) by redefining the existent elements and adding some new elements, which would support the contextualization of learning units in our proposed learning contexts. We also proposed a process for the production of learning units, which allows us to transform the original documentations, such as paper manuals or other electronic documents, into learning units in XML format, store and index them in database. The conception of SAMCCO is based on the IMERA (Computer Augmented Environment for Mobile Interaction) platform designed by our research team which concerns the following augmentations: augmented learners, augmented environment and augmented appliances. Learner's requirements and learning context in professional situations were identified and modeled in the conception of system. Learning methods such as just in time learning, learning by doing and collaborative learning were properly adapted into professional learning activities. The system architecture is based on models (generic services, databases, interaction patterns, etc) and explains how the learning system works. The objective of SAMCCO is to augment the learning efficiency and working performance associated in the activities of mastering domestic, public and professional appliances with MOCOCO characteristics. Based on the principles of our approach, we made several applications to validate the interest of SAMCCO in different concrete situations. MAPED test bench scenario allowed us to validate the process of the production of learning units in a precise industrial case. The scenario of computer maintenance is an application of contextual mobile learning in the activity of appliance maintenance. HSHB (Healthy Spirit in Healthy Body) project illustrates another type of contextual mobile learning for establishing a balanced meal in self-service restaurant, in which our system design was also used.
