In this paper, we present the modeling, design, and a segment of the implementation of an Open Personalized Learning Environment (OPLE) for the Electrical Engineering course that is taught at Vocational Schools. We describe in detail how the chapters of the course are used in the online environment. As methodological principles of this construction we emphasize on the students’ learning behavior, and on the individualized promotion of knowledge, considering the simplicity and the dynamics of the open personalized environment.
