Description
During lectures, projection equipment is employed to present both static and dynamic slides comprising textual content, diagrams, and visual representations of complex devices. The objective is to facilitate deeper conceptual understanding among students. Communication with students is conducted through the full spectrum of institutional tools, including electronic mail, teleconferencing platforms, and the online educational environment hosted at elearning.auth.gr. This e-learning platform is also utilized occasionaly for student and evaluation.
