The e-learning applications developed in the research project cover all the aspects of the educational process (teaching, learning, assessment). During the project, several e-learning technologies were integrated, both traditional (e.g. distant virtual classes based on online real time videoconferences using Skype) and modern (desktop and mobile Virtual and Mixed Reality applications, which were used to display 3D reconstructions and virtual immersive tours, or social media for distribution of the lesson and collection of learning feedback), complementarily with classroom workshops, organized with children and teaching assistants from the NUA.
