The e-COMODE eTEN project started in April 2005. e-COMODE offers schools an open digital learning environment, which assists young students in creating models. This computer-based environment supports students in expressing their ideas, building, designing and testing models of various situations with rich visualisation and simulation tools. Moreover, the e-COMODE eLearning Environment encourages and supports collaborative problem solving and online communication with peers and teachers, promoting the acquisition of these skills, which are also extremely important for the young students’ future.
