The participants will be guided by one of the teacher trainers of our team, who will accompany them during the two weeks of classroom observation and practical teaching exercises. They can be present during class preparation, observe their tutor in class, deliver short teaching units and receive feedback after class. Each observation will be complemented by specific tasks that will be defined before class. These tasks will help participants in becoming aware of the different factors that influence the teaching of a class. We use video recordings to analyze the class, to evaluate if the objectives have been achieved, and to observe specific aspects (such as the students’ group, the attitude of the teacher), etc. In the same way, participants will also use a diary, in which they can note down their questions, doubts, impressions, proposals, ideas, etc. This diary can be used for the final feedback session of the course to extract the most important conclusions.
