In this paper a conceptual model for e-learning, which uses elements from learning Objects and Concepts Maps, is introduced. The learning material is divided into atomic units and organized in graphs called Knowledge Map, Learning Map and Student Map. Such a structure provides an easy-to-use navigation interface for existing learning material. Any course content created is stored in a repositor...
