This paper describes the course of an alternative teaching and learning proposal, which works from the perspective of cross curricular teaching through the use of ICT in education, and aims at interdisciplinary action among philologists and teachers of various specialties for the teaching of the Modern Greek Language course. Through collaborative, experiential and "playful" creations, a digital interactive crossword and an auxiliary theatrical play, this view is akin to the principles of Modern Pedagogy and Constructivism highlighting the student culture, without neglecting the presence of the teacher. It therefore looks forward to the constructive and sound interdependence of the basic elements of the school action, pupils-teachers and peer-to-peer, in the environment of a school, in order to ensure their cognitive and pedagogical formation and integration. The activity is complemented and reinforced by the on-site observation, where the views of ... energon participants are explored about the application of the two cross-thematic creations in their educational reality.
