This work is inscribed in the framework of the author’s doctoral hood under way, whose thematic is part of the research and investigation project: “Obra Abierta en Image Campus: Hacia la construcción e implementación de un modelo teórico y metodológico para investigar y aprender en ambientes presenciales-virtuales organizacionales de educación superior” (Dir. PhD. Patricia San Martín, CONICET-UNR) During the academic year 2006 a physical-virtual-interactive-communicational workshop was designed and destined to educational and university students, implemented in the Faculty of Psychology (UNR). The research progress showed that the platform Moodle possesses activity registrations with static characteristic, which can be viewed as an action list. However, it does not re-enter (no retro-feed) into the system as data. The relations of this modality of workshop (students/educational - tools) are based on norms, rules and restrictions strongly linked to the possibilities of interactiveness that the current information and communication technologies and the communication offers. It requires a tool that can be capable to be context adapted (in this case, by the student) and from there on, to moderate (in a flexible form) the real time user intervention (feedback), the contracts coordination theory is a feasible model to such end. Contracts Coordination is a modeling and primitive implementation that allows transparent interception of messages and as such replaces the services method by the code provided by the coordination contract, providing object-oriented interactions and run-time integration of services. To be more precise, a coordination contract is applicable to one or more objects (called the contract’s participants) and has one or more coordination rules, each of them indicating which method of which participant will be intercepted, under which conditions and context, and what actions have to be taken in such case. We defined a pedagogic rule to be given by a condition, an action, and a priority. The condition is a Boolean expression over relations (greater, equal, etc.) between parameters and concrete values. The available parameters are defined by the rule type. The MConditional is a special condition which is implemented with an innovator metric INCAMI (Information Need, Concept model, Attribute, Metric and Indicator). (Olsina et. al.) INCAMI is an organization, purpose-oriented measurement and evaluation framework which allow consistently savings, not only metrics metadata and indicators, but also values for concrete real-world measurement (e.g. e-learning interactivity, involved in a Mconditional). This type of value gives additional context information, enriching the semantic expression of the contact context-aware (in this case, utilized to implement the above conceptual lasso) Our concrete contribution is: the definition of the tree concept (according to INCAMI methodology) to measure student-interactivity and propose an object oriented design to integrate our model of contract context-aware with a model of metric of Olsina et. al. across of MConditional.
