In the framework of the New National Curricula and of the new in-school Mentor Teacher and Subject Coordinator institutions, a model Literature lesson was delivered implementing the new, nationally introduced teaching methodologies in class B2 of our school. The teaching event took place on Wednesday 1/11/2023. The model lesson methodology implemented was that of co-teaching by the Advisor for Greek Language Teachers of Peiraias Dr C. Koumbarou and Ralleio teacher of Greek Language Dr M. Panagiotopoulou. The model lesson was observed by Ralleio teachers as well as by teachers form other junior and senior high schools of Peiraias and was later commented on by all participants. The fruitful discussion that followed also provided an excellent opportunity to analyze the rationale of the new National Curricula. In general, the event was very successful as B2 class students stated that they enjoyed the process and teachers expressed their interest in organizing more events of the kind.
