A component of the Faculty's Pre-service EFL teacher-training programme, this is one more course that builds on the knowledge and skills that students developed by having successfully completed, in previous semesters, two relevant core courses (Applied Linguistics to Foreign Language Teaching and Learning; ELT Methods and Practices). Its purpose is threefold. Firstly, it aims at providing trainees with the opportunity to take the position of an informed observer in an EFL classroom in a Greek school and to systematically follow and reflect on the processes of teaching and learning therein. Secondly, it aims at familiarizing them with classroom conditions and the discursive practices of participants in the teaching/learning process from the position of a teaching assistant. Thirdly, it aims at providing them with an opportunity to carry out supervised teaching for a short period of time. The trainees are evaluated by the EFL class teacher that they assist, but also by the course instructor who assesses trainees? experience recorded by them in written form through a portfolio.
