A task-based production environment for intelligent learning/teaching systems: the ´NGE´ kernel

After many studies, experiments, and assessments on the design and development of intelligent learning/teaching systems, we are now offering a production environment for these systems and shells. This environment is based on high abstraction level primitives: the ´NGE´ kernel. Elaborated in a cognitive approach, these primitives have been defined on the notion of task (generic, cognitive, operating), not only to define the different levels of abstraction but also to improve the interactions between the universe of teachers, pedagogues and the universe of computer science.
