Graphical model: The means for simulation-based learning

Simulation-based e-learning is recently budding demand for the next generation of e-learning. Learning about dynamic phenomena is essential in many domains. That approach allows the student to imitate real processes using models and to obtain knowledge and experience during the process of learning. The proposed graphical modelling method is based on systematic point of view, experiential learning and expert-based modelling requirements. The contextual graph of action specification is used as a basis to set the requirements for service software specification and attributes of learning objects (LO). The paper presents the enhanced architecture of the student self-evaluation and on-line assessment system TestTool (TT). The system is explored as an assessment engine capable of supporting and improving the individualized self-instructional and simulation-based mode of learning, grounded on the GRID distributed service architecture. This architecture, services and method are being examined in study modules for Kaunas University of Technology (KTU) students and some organizations.
